SYMPTOMS
When you work with a Microsoft Visual Basic solution that contains many projects in Microsoft Visual Studio 2005, you may experience the following performance issues in the Visual Studio 2005 IDE:
- You experience a slow response time when you use single-step debugging. For example, the response time is slow when you press F10 to step into a line of code.
- You experience a slow response time when the Error List or the Task List is updated by Visual Studio 2005.
- You experience a slow response time when you use the IntelliSense feature.
RESOLUTION
Hotfix information
A supported hotfix is now available from Microsoft. But the hotfix is intended only to correct the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Visual Studio 2005 service pack that contains this hotfix. To resolve this problem immediately, visit the following Microsoft Web site:
Prerequisites
You must have Visual Studio 2005 installed to apply this hotfix.
Restart requirement
You do not have to restart the computer after you apply this hotfix.
Registry information
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To obtain improved performance from this hotfix, add and then enable the OptimizePDB registry value. To do this, follow these steps:
- Click Start, click Run, type regedit, and then click OK.
- Locate and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\VB EditorNote If you are using Visual Basic Express, the registry key should be the following:
HKEY_CURRENT_USER\Software\Microsoft\VBExpress\8.0\VB Editor - Click Edit, click New, and then click DWORD Value.
- Type OptimizePDB, and then press ENTER.
- Right-click OptimizePDB, and then click Modify.
- Type 1, and then click OK.
- Exit Registry Editor.
After you add theOptimizePDBregistry value, open the Visual Basic solution in Visual Studio 2005. Then, click Clean Solution on the Build menu.
The OptimizePDB registry value makes the Visual Basic compiler optimize the .pdb file to improve performance. However, the new .pdb file format is not fully compatible with the old .pdb file format. Therefore, a version of Visual Studio 2005 that does not have this hotfix applied may be unable to read the new .pdb file format. To resolve this issue, apply this hotfix on all development computers, or click Clean Solution or Rebuild Solution on the Build menu before you start debugging the solution.
