Consider the following scenario:
When you are developing the custom application by using VSA, you may experience the following problem. When the custom application calls the Microsoft.VisualBasic.Vsa.VsaEngine.Compile method, an exception is thrown by the VSA Visual Basic Runtime to the host. The host may trap the exception, and the user may receive the following error message:
Alternatively, the host may ignore the exception, and one of the following symptoms may occur:
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
When you try to run macros in the custom application, you may experience one or more of the following symptoms:
This problem occurs because of a recent design change in the CLR workstation runtime (Mscorwks.dll) for builds of the .NET Framework 2.0 that are later than 2.0.50727.300. This change introduced a compatibility problem for the Visual Basic Runtime engine (Vsavb7rt.dll) that is used by VSA. The problem prevents assemblies from beng generated correctly during the macro compile operation.
This problem may cause the exception error message that is mentioned in the "Symptoms" section to be returned to the host application. The host application may report this error to the user in some manner. Alternatively, the host application may throw an exception and exit unexpectedly.
Note Custom applications that use the full-feature Microsoft Visual Studio for Applications Software Development Kit (SDK) and the .NET Framework 1.1 do not experience this problem. This problem occurs only in host applications that use the VSA runtime that is included with the .NET Framework 2.0.
