SYMPTOMS
In Microsoft Visual Studio .NET 2003, the CDatabase::Connect method passes an incorrect buffer size to the SQLDriverConnect function in a Microsoft Visual C++ .NET solution. Additionally, the application that makes this function call may close unexpectedly.



CAUSE
This problem occurs because of a bug in the CDatabase::Connect method in the Dbcore.cpp file. The incorrect buffer size is passed to the SQLDriverConnect method. Therefore, the application closes.
