Visual Basic Q&A

Symptoms
You have a Visual Basic ActiveX DLL that has a method that takes an array of Scripting Dictionary Objects as an argument. It may work fine when your Visual Basic client is run in the Visual Basic integrated development environment (IDE) by using this method, but when you run it as a compiled application, you get the following run-time error message:

Run-time error ‘-2147417848 (80010108)’:
Method ‘~’ of object ‘~’ failedThis only occurs when you use late binding to call the method.
Resolution
Use early binding to work around the problem.

Symptoms
When you view an XML document with Data View in the Microsoft Visual Studio .NET integrated development environment (IDE), you may receive the following error message:

Although this XML document is well formed, it contains structure that Data View cannot display.
The grid cannot show the data correctly because of the unsupported character “.” in element name(s).
Resolution
The XML document has an element name that contains a period (.), and the period (.) is an unsupported character.

Symptoms
When you use Visual Basic .NET to create two Windows Control Libraries (UserControls) that have a circular reference between them, and then you try to add one control onto another, the integrated development environment (IDE) may close (crash) without warning.
Resolution
The stack overflow exception is not properly trapped.
