Re: __declspec(dllexport) to return char but errors in VB6

Thank you for your reply!

I was switching code around and placed the FreeHGlobal in the wrong place
for my post.

changing it to this

WDINFO_LINKAGE char* getWdInfo(char* Param){

IntPtr ptr = Marshal::StringToHGlobalAnsi(S"Testing return");
char __nogc* pStr = static_cast<char*>(ptr.ToPointer());

return pStr;

Marshal::FreeHGlobal(ptr);
}

doesn't give me the error but doesn't return anything back.

Thanks in advance.
