The following error may occur when the if expression uses Byte data type:
"Run-time error '6'. Overflow."
Visual Basic does not evaluate Byte data type correctly in the if expression when compiled to Native code with optimizations.
Install Visual Studio 97 Service Pack 2 (SP2). The problem can also be addressed by compiling to P-code, compiling to Native Code with no optimizations, or using a data type other than the byte data type in the if expression.
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been fixed in Visual Studio 97 Service Pack 2.
For more information on the Visual Studio 97 Service Pack 2, please see the following article in the Microsoft Knowledge Base:
