Error message when you upgrade a Visual Basic 6.0 project to Visual Basic .NET 2003: "UserControlName.ToolboxBitmap was not upgraded" (820650)


The information in this article applies to:

  • Microsoft Visual Basic .NET (2003)

SYMPTOMS

In Microsoft Visual Basic 6.0, if you upgrade an ActiveX Control project or a project that contains a user control file by using the Visual Basic Upgrade Wizard, and the ToolboxBitmap property is set for the user control file, then the Visual Basic Upgrade Wizard reports the following error:
UserControl property UserControlName.ToolboxBitmap was not upgraded.
Therefore, when you build your project in Microsoft Visual Basic .NET, you receive the default bitmap of the user control file that is in the toolbox instead of the ToolboxBitmap that you selected in the Visual Basic 6.0 project.

WORKAROUND

To work around this problem, add the ToolboxBitmapAttribute to the user control after you upgrade your Visual Basic 6.0 project. To do this, follow these steps:
  1. In Solution Explorer, right-click Project Name, point to Add, and then click Add Existing Item.
  2. Locate the .bmp file that is associated with the user control file, and then click Open.
  3. Rename the .bmp file to the user control name.

    For example, if the user control name is UserControl1, rename the .bmp file UserControl1.bmp.
  4. In Solution Explorer, right-click the .bmp file, and then click Properties.
  5. In the Properties window, set the Build Action property to Embedded Resource.
  6. In Solution Explorer, right-click UserControl1.vb, and then click View Code.
  7. Add the following ToolboxBitmap attribute to the UserControl1 class:
    <ToolboxBitmap(GetType(UserControl1), "UserControl1.BMP")> _
 Public Class UserControl1
	...
End Class

STATUS

This behavior is by design.
