Hello everyone, I have a function CallerFunc( ) in a C# exe calling another function MyFunc( ) from C++ dll. MyFunc( ) deserializes an XML request and initializes Mapi using MapiInitialize. The first time call to MyFunc( ) is successful and I can do all MAPI stuff successfully. However, at the second call to MyFunc( ) from CallerFunc( ), I get an exception while deserializing XML in MyFunc( ). Weird thing is that if I don't call MyFunc( ) from a C# code but from a C++ test exe utility, there's never an exception. Also, if I comment out MAPI portion of the code from MyFunc( ), there's never an exception if called from C#. It appears that the exception is caused by MapiInitialize in an interop environment. Any ideas? Caller function in C# CallerFunc( ) { MyFunc( ) ................ //some code here ................ MyFunc( ) ////Exception occurs if MyFunc is called second time } Called function in C++ void MyFunc( ) { //XML deserialization ////Exception occurs here MapiInitialize(NULL); .......... //some code here ......... MapiUnInitialize( ); return; }
