Packages Fail to Load or Installation Fails Due to Data Execution Prevention Setting

Systems with the Data Execution Prevention (DEP) setting configured as /NoExecute=Always On and the CPU's Execute Disable bit enabled might prevent DevPartner Studio from loading into Visual Studio.

See article number 875352 in the Microsoft Knowledge Base for a detailed description of the Data Execution Prevention feature.

System-wide DEP is set in the BOOT.INI file using the /NOEXECUTE option on the system boot partition. By default this is set to OptIn, which specifies that DEP is only enabled for essential Windows programs and services.

Setting this to AlwaysOn causes the DevPartner Studio installation to fail, and if the setting is changed to AlwaysOn after installation it will cause the DevPartner Visual Studio package to fail to load into Visual Studio.

If you set DEP to OptOut, be sure to include the Visual Studio executables (DEVENV.EXE for Visual Studio 2003 and 2005, MSDEV.EXE for Visual Studio 6) in the list of programs and services that are not to run with DEP.

Mach 5 Driver Not Starting on Vista

Applies to Performance Analysis and Performance Expert

On Vista systems with UAC enabled, if you run Visual Studio 2005 without Administrative privileges, the Mach5 driver required for performance profiling is not started. Performance Expert will be non-functional, and performance analysis will provide inaccurate data. To correct this condition, run Visual Studio 2005 as an administrator, as suggested by Microsoft, or manually start the Mach5 driver with the net start mach5 command.

No Data for Certain Lines in Partial Classes in Visual Studio 2005

Applies to Coverage Analysis, Memory Analysis, Performance Analysis, and Performance Expert

There is a known issue with displaying data collected for static initialization of member fields of partial classes in which a constructor is implemented in a different source file than the statically initialized fields. In these cases the source view will show no data for the static member field initialization. This is because the data is attributed to the constructor of the partial class and not the assignment statement for the static initialization of the field. If a source file only contains statically initialized member fields for a class, the source file will not be shown in the list of source files for the module in the results.

Administrative Privileges Required to Build BugBench on Vista

Applies to Error Detection

When you build the BugBench sample on Vista, you must have Administrative privileges. Building the sample generates a COM DLL that must be registered. Vista will not allow the DLL to be registered if you lack sufficient privileges.

Back to Known Issues

Target Names and Paths Must Exactly Match Those Provided to Error Detection

Applies to Error Detection

To ensure successful monitoring of your application when using Wait for Process under the standalone version of Error Detection, the target names and paths must exactly match what you specified to Error Detection. If you use an intermediary step that somehow changes the target names or paths, Error Detection may not recognize that your application has launched. For example, if you select an executable (C:\MyApplications\foo.exe) as your target, select Wait for Process, and then launch an intermediary application that changes the fully qualified names to short names and launches C:\MyAppl~1\foo.exe, Error Detection will not recognize that your application has been launched.

Team Foundation Server Source Control Not Compatible with Code Review

Applies to Code Review

When a Visual Basic 6.0 component is loaded into a Visual Studio 2005 Integrated Development Environment process and the user adds a solution to Team Foundation Server Source Control, the Integrated Development Environment will essentially lock up. Since code review uses some Visual Basic 6.0 components, this problem may occur on systems on which DevPartner Studio is loaded.

Microsoft has developed a hotfix for this problem. Visit http://support.microsoft.com/?kbid=922989 for information about this hotfix.

Opening Legacy Solution Files in Visual Studio 2005

Applies to Coverage Analysis, Error Detection, Memory Analysis, Performance Analysis, and Performance Expert

If you attempt to open a legacy solution file, Visual Studio 2005 may display the following error message: The selected file is a solution file, but appears to be corrupted and cannot be opened. The problem is due to an obsolete entry in the solution file written by an earlier version of DevPartner Studio. You can safely remove this entry using Notepad. To remove the entry:

  1. Exit Visual Studio 2005.
  2. Open the solution file in Notepad and remove the following lines from the Global section of the solution:

    GlobalSection(DevPartner Solution Properties) = postSolution
    EndGlobalSection

  3. Save the file.
  4. Start a new Visual Studio 2005 session, and open your solution.

Profiling System Services through Terminal Services

Applies to Coverage Analysis, Memory Analysis, Performance Analysis, and Performance Expert

In some cases, when you profile custom Windows services while logged in through Terminal Services, you may not get session files. If this occurs on your system, you may be able to save the session data by specifying the full path and filename for the session file. For example: 

DPAnalysis.exe /cov /output c:\temp\MyService.dpcov /s MyService

Note: This may not work in all cases.

Error Detection Displays Inaccurate Reporting if Module Compiled with Visual C 6

Applies to Error Detection

The linker option /pdbtype:sept is no longer supported by the Microsoft debug file access routines. By default, projects created by the Visual C 6 Integrated Development Environment set this option. You can remove this switch with no other impact on your project, and then continue with compilation and re-linking. If the module is being instrumented for Error Detection, the instrumentation process temporarily removes this linker option and resolves potential issues. However, if you are not instrumenting the module, Error Detection cannot detect whether this linker option was used to create the module, and you may encounter problems.

Examples of Inaccurate Reporting
Work Around Solution

If you are building outside of the Integrated Development Environment, you will only see this issue if you explicitly added /pdbtype:sept to your makefile(s). If a makefile includes the /pdbtype:sept text, you should edit the makefile and remove it.

Error Detection Collects No Data for DCOM or COM-based Applications/Components

Applies to Error Detection

There are two situations in which DCOM or COM-based applications or components try to run under the restrictions of the aspnet account.  By default, when a DCOM or COM application or component is launched from within an ASP.NET enabled Web page, it will run in the context of the aspnet account. For security reasons, the aspnet account is a restricted account (it is a member of the Users group and has equivalent privileges). In this situation your COM component will not have the security privileges required for Error Detection to function properly. To work around this issue, you must configure your DCOM or COM application or component to execute within the context of the interactive user (via dcomcnfg.exe).

To configure your DCOM or COM application or component to run under the context of the interactive user:

  1. Open a command prompt and run dcomcnfg.exe.
  2. Expand Component Services > Computers > My Computer > DCom Config.
  3. Right-click on your COM component, and select Properties.
  4. Select the Identity tab.
  5. Ensure that you have selected The interactive user.
  6. Click OK.

Error Detection will collect data properly the next time the DCOM or COM application or component is launched.

Unidentified GC Roots for Applications Run Under the Debugger

Applies to Memory Analysis

If you attempt to collect Memory Leaks or RAM Footprint data for a memory analysis session started under the Visual Studio .NET debugger, garbage collection roots will appear as "unidentified GC roots" in the session data. To enable DevPartner Studio to properly identify most garbage collection roots in Memory Leaks or RAM Footprint sessions, start memory analysis for your application without debugging.

Back to Known Issues

Spurious Data from Temporary Source Code When Profiling Web Applications

Applies to Memory Analysis and Performance Expert

Running Memory Analysis or Performance Expert on Web applications (such as those created with a wizard in Visual Studio 2005) generates a small amount of spurious data. Regardless of the number of lines in the source file, the spurious data appears on lines with numbers greater than 912,304, and may be safely ignored.

Back to Known Issues

Root References to String Objects in J# Application Data

Applies to Memory Analysis

In Memory Analysis session files for J# applications, the Object Reference graph may show two root references for some String objects, due to the way the .NET Framework handles internal system String objects. In such cases, the graph shows one root reference from an object array and an independent reference from a String array. In contrast, the Object Reference graph for a C# application typically shows a single root reference to the String objects.

Back to Known Issues

CPU Time Charged to Wrong Line in For Loop

Applies to Performance Analysis and Performance Expert

In some cases, CPU time attributable to the expression part of a For loop can be incorrectly attributed to the body of the For loop. This can occur in loops formatted so that the initializers, expression, and iterators appear on a single line, as in the example below.

			using System;
			public class ForLoopTest 
			{
			   public static void Main() 
			   {
			      for (int i=1; i<=5; i++) 
			          Console.WriteLine(i);
			   }
			}

If the body of the For loop appears to be consuming excessive CPU time, reformat your code so the initializers, expression, and iterators appear on separate lines, as shown below.

			{
			   for (int i=1;
			        i<=5; 
			        i++)
			        Console.WriteLine(i);
			}

Visual Studio Unresponsive When Running Different Analysis Type After Performance

Applies to Performance Analysis

If you attempt to run a coverage analysis, memory analysis, or Performance Expert session immediately after running a performance analysis session on an ASP .NET Application running under IIS 6.0, Visual Studio may stop responding.

To recover from this situation:

  1. Restart IIS to put Visual Studio back into a responsive state. From the Start menu, select Run and type iisreset in the Open field.
  2. Restart your session.

There are two ways to avoid this situation:

Performance Analysis too Slow on Low-end System

Applies to Performance Analysis

If Performance Analysis runs too slowly on a supported low-end PC (for example, a 733 MHz Pentium III), you can speed up performance analysis sessions by changing the processor scheduling to provide equal processing priority for background services.

  1. Open System Properties: Click Start > Run and type sysdm.cpl and click OK.
  2. On the Advanced tab, under Performance, click Settings.
  3. On the Advanced tab of Performance Options, under Processor scheduling, select Background services and click OK.
  4. Click OK to exit System Properties.

Merging Coverage Files for ASP.NET 2.0 Applications

Applies to Coverage Analysis

You may be unable to merge coverage session files for ASP.NET 2.0 applications. 

DevPartner Studio can only merge coverage session files from the same build of your ASP.NET 2.0 application. With ASP.NET 2.0, the executable name changes every time you rebuild the solution.

To avoid this problem, run all coverage sessions that you intend to merge without rebuilding your application between sessions.

Back to Known Issues

Using Fault Simulator with Coverage Enabled

Applies to Coverage Analysis

If code coverage is enabled and you use Fault Simulator to add a source-based .NET fault where the code construction includes compound or nested source statements on a single line, Fault Simulator might be unable to properly evaluate the designated method call. As a result, Fault Simulator might not fire the corresponding fault as expected during the fault simulation.

As a workaround, break out the source statement into multiple lines of code. Consider the following examples:

Example 1:

Change from this construction:

DateTime[] dates = new DateTime[]{
new DateTime(2000, 1, 1),
new DateTime(2001, 1, 1, 0, 0, 0)};

To this construction:

DateTime dt1 = new DateTime(2000, 1, 1);
DateTime dt2 = new DateTime(2001, 1, 1, 0, 0, 0);
DateTime[] dates = new DateTime[]{dt1, dt2);


Example 2:

Change from this construction:

Label1.Text = Environment.GetEnvironmentVariable(“TEMP”);

To this construction:

String text = Environment.GetEnvironmentVariable(“TEMP”);
Label2.Text = text;

Internet Information Server Error During Coverage or Performance Analysis

Applies to Coverage Analysis and Performance Analysis

When running coverage or performance analysis, Visual Studio may become unresponsive and then display the following error: 

Could not restart Internet Information Server (code %d). 

(In the message above, %d represents an internal error code. In the context of this issue, you can ignore this code.)

If this occurs several times, make sure that Internet Information Server is running. If it is not running, exclude system DLLs and try again.

If the problem persists, use DPAnalysis.exe from the command line to analyze the application. Run DPAnalysis.exe through a configuration file that excludes inetinfo.

For more information, see the topic Using DPAnalysis.exe in the DevPartner Studio online help or Appendix C in the Understanding DevPartner manual.

Session Control Toolbar Unavailable When Running Fault Simulator and Coverage Analysis Sessions Simultaneously

Applies to Coverage Analysis

On systems with both DevPartner Fault Simulator 1.5 and DevPartner Studio installed, you can run Fault Simulator and Coverage Analysis sessions simultaneously. (To do this, choose Fault Simulator > Start with Fault Simulator and Coverage Analysis or Fault Simulator > Start Without Debugging with Fault Simulator and Coverage Analysis.)

In some cases, when running Fault Simulator and Coverage Analysis sessions together on a managed standalone Windows application, the DevPartner Session Control toolbar may be unavailable. This will prevent you from using the Stop Recording, Take snapshot, and Clear all recorded data functions during the session.

If your Coverage analysis requires use of the Session Control toolbar functions, try one of the following workarounds:

Wrong Source Code Data Appearing in Description Pane

Applies to Code Review

In some instances, DevPartner Studio intermittently displays the wrong source code line in the Description pane (on the Problems pane) following a code review. This problem is related to underlying Microsoft code. While it is intermittent and random, it does not impact the accuracy of code review results or the ability for DevPartner Studio to successfully perform a Go to Source operation for the rule in question. As a workaround, use the Go to Source function to access the correct location of the source code related to the rule firing.

Code Review Only Prints Reports to Default Printer

Applies to Code Review

Code review will only print reports to the default printer. When the Print button or menu option is selected in the code review problems pane, a dialog box appears. This dialog box controls the settings for printing, and allows you to select a specific printer other than the one currently set as default. However, the report will only print to the default printer, regardless of which printer is selected. The work-around is to change the default printer before attempting to print reports from code review.

'No Problems' Reported Following a Code Review When Rational XDE Plus Also Installed

Applies to Code Review

If DevPartner Studio and Rational XDE Plus are both installed on the same machine, it is possible that incomplete results might be generated during a code review. In this case, No Problems will appear on the Problems pane following a code review on a solution, rather than a complete list of rule violations that you expect to see. The workaround is to uninstall both DevPartner Studio and Rational XDE Plus. Then, reinstall DevPartner Studio before you reinstall Rational XDE Plus. If you install Rational XDE Plus first, you will continue to see these symptoms in DevPartner Studio.

Batch Code Reviews Tied to Source Control

Applies to Code Review

DevPartner Studio will be unable to perform a code review in batch mode if the solution in question is integrated in a source control system. This is not a DevPartner Studio bug, but a Microsoft constraint. DevPartner Studio has no control over the source control integration behavior in the Visual Studio Integrated Development Environment. Source control error messages will be generated even if the Integrated Development Environment is run in Automation mode, such as how the command line interface runs.

The workaround steps follow:

  1. From Windows Explorer, delete the .suo file.
  2. Open the solution in the Visual Studio Integrated Development Environment.
  3. Click OK to navigate past the various dialog boxes that are generated.
  4. Perform an interactive code review in DevPartner Studio.
    Refer to the DevPartner Studio code review online help for instructions.
  5. Exit completely from the Visual Studio Integrated Development Environment.
  6. Run a code review batch session from the command line.
    Refer to the DevPartner Studio code review online help for more information.
    Notice that a few dialog boxes will appear sequentially.
  7. Click Cancel on the SourceSafe logon dialog box.
  8. Click Work Disconnected on the Change Source Control dialog box.
    The batch review will proceed. Subsequent batch reviews will also proceed uninterrupted.
  9. To reproduce, delete the .suo file and then attempt to run a batch review.

Use of Pipe Character (|) in 4NT When Running Migration Utility Programs

Applies to Code Review

When you use 4NT to run the crupdaterules.exe or crupdateprefs.exe migration utility programs, you will encounter a problem if you enter a pipe character (|) as part of the old database path. For example:

crupdateprefs | <path>

Normally, a message would appear in a non-4NT DOS window indicating that you specified an invalid path to the DevPartner Studio database. However, when you include the | character in the command using 4NT, no error message will appear. 4NT prevents the error message from being written to the console despite the presence of the invalid use of this character. The following is an example of a valid command for the rules migration:

crupdaterules C:\MyOldRulesDb\CRRules.dpmdb
Note: Refer to Migrating DevPartner Code Review Custom Rules and User Preferences in the DevPartner Studio Installation Guide for more information.

Running English Version of DevPartner Studio Code Review Feature under Japanese Operating System

Applies to Code Review

If you are running an English version of the DevPartner Studio code review feature under a Japanese operating system, some controls in the code review feature and in Rule Manager will not display Japanese text properly. For example, in DevPartner Studio code review, the Solution Tree nodes appear with indecipherable characters. In Rule Manager, indecipherable characters appear in the user interface, i.e., in the New Rule or Edit Rule dialog boxes.

The workaround in the DevPartner Studio code review feature is to focus on the contents of the Problems pane, which are not distorted. The columns labeled File, Project, Method, and Class appear with valid Japanese text. You can customize the results view by rearranging the left-right orientation of those columns for more visibility in the pane. Refer to the DevPartner Studio code review online help (Customizing the Results View) for more information. With Rule Manager, for consistency sake, it is recommended that you enter or edit rule data in English only.

Visual Basic .NET Code Containing Declare Statement with Alias Clause

Applies to Code Review

Any Visual Basic .NET code that contains a Declare statement with an Alias clause will be bypassed in a code review when the DevPartner Studio API rules are used to scrutinize the code. This limitation is due to an accuracy issue regarding declared APIs that are also aliased. This limitation only pertains to Visual Basic .NET Declare statements with an Alias clause. Any DLLImport attributes placed on Visual Basic .NET or Visual C# API methods declared as external will still be reviewed successfully.

Zero Impact Projects (ZIP) in Visual Studio 2005

Applies to Code Review, Coverage Analysis, Error Detection, Memory Analysis, Performance Analysis, and Performance Expert

In Visual Studio 2005, you can create a zero impact project (ZIP) by disabling the Save new projects when created option in the Tools > Options > Projects and Solutions > General options page. However, disabling this option prevents DevPartner Studio from creating a virtual folder for the session file in Solution Explorer or storing the session results in that folder. For best results in collecting data from your project:

If you launch a session without saving the project, click Save when Visual Studio presents the message "The current project must be saved before adding a project". Visual Studio will rename the project and store it in Solution Explorer. Although the session file is created in this scenario, it will contain references to the temporary locations of the project source code and executable modules, as well as the temporary project name. We do not recommend running the DevPartner Studio on Visual Studio 2005 "ZIP" projects.
