FIX: The Visual Studio .NET 2002 IDE crashes when a double array property of a user control is set to a very small value or to a very large value

View products that this article applies to.

SYMPTOMS

The Microsoft Visual Studio .NET 2002 IDE stops responding when you build a solution or when you try to open a form that hosts a Microsoft .NET Framework 1.0 user control in Designer view. This problem occurs when a double array property of a user control is set to a very small value or to a very large value. You do not receive an error message when this problem occurs. If you try to reopen the solution, the Visual Studio .NET 2002 IDE stops responding again. You still do not receive an error message. A value such as 1E210 could cause this problem to occur.
