This article was previously published under Q316189
SYMPTOMS
When you attempt to upgrade a Microsoft Visual Basic 6 project to Visual Basic .NET, and the project contains a UserControl, the Upgrade Wizard may stop responding (hang) or throw an exception.
Specifically, when you perform the upgrade on a Microsoft Windows XP-based computer, the Upgrade Wizard may stop responding. When you upgrade on a Microsoft Windows 2000-based computer, you may receive the following error message:
NOTE: The Visual Basic .NET Upgrade Wizard is included in Visual Studio .NET Professional.
CAUSE
This behavior can occur if an instance of the UserControl cited on a form has the same name as the project.
RESOLUTION
To resolve this issue, change either the name of the project or the name of the UserControl before you run the Visual Basic Upgrade Wizard.
STATUS
This bug was corrected in Microsoft Visual Basic .NET (2003).
MORE INFORMATION
Although UserControl projects are not supported by the Visual Basic Upgrade Wizard, the wizard should not stop responding or return exceptions when you upgrade a supported project type that contains a UserControl. Rather, the wizard should ignore the control and not make any modifications to the control file.
Steps to Reproduce the Problem
- Create a new standard EXE project in Visual Basic 6.
- On the Project menu, click Add User Control to add a UserControl to the project.
- Make a note of the project name. You can obtain this information by clicking the Project Properties link on the Project menu.
- Cite the UserControl on the form.
- Set the name of the UserControl equal to the project name noted in step 3. You can do this through the Properties window (press F4 to display this window).
- Save the project.
- Open the Visual Basic 6 project file in Visual Studio .NET.
The project file should have a .vbp file extension.
- Step 7 should start the Visual Basic Upgrade Wizard. Accept all of the defaults.
Note that the wizard stops responding during the upgrade process.
NOTE: You can also start the Visual Basic Upgrade Wizard from the command-line. The wizard is installed to the following directory, by default:
Visual Studio .NET Install Directory\Vb7\VBUpgrade
