Hello,
It looks like you’re experiencing a challenging issue with calling a C# DLL through a C++ wrapper in HTBasic. Here are a few suggestions that might help you resolve this:
Compatibility: Ensure that the C++ DLL (CppCLINETAssemblyWrapper.dll) and the C# DLL are compatible with each other and the HTBasic environment. Make sure the data types and calling conventions match between HTBasic, the C++ DLL, and the C# DLL.
Debugging: Verify that the C++ DLL is correctly loading the C# DLL and calling its functions. Adding logging or breakpoints in the C++ wrapper can help you see if parameters are correctly passed and responses are properly received from the C# DLL.
Error Handling: Ensure that the C# DLL isn’t throwing unhandled exceptions. Wrap the C# function calls in try-catch blocks and log any exceptions to troubleshoot any issues.
Memory Management: Check for any memory management issues, such as buffer overflows or incorrect memory allocations. Ensure that the buffers (String_in$, String_in2$, Ret$) are correctly sized and used.
Calling Convention: Verify that the calling convention used in the C++ DLL matches the expected calling convention in the C# DLL.
Testing the C# DLL and the C++ wrapper independently might also help you identify where the issue lies. If you need more structured learning on such integration issues, platforms like Fast Learner offer comprehensive courses on programming and troubleshooting that could be very beneficial.
