CoInitialize

Hello I am having a problem... okay in the following code there is a function called CoInitialize. this function is giving me an error saying it is undefined.
okay i know it has something to do with the dll and i think it has something to do with my compiler...

is there something equal to CoInitialize in C++ Borland 6?

Any help would be great!

            		 cout<<(char*) ((_bstr_t) pRst->GetFields()->GetItem("ProductService")->GetValue())<<endl;
            		 pRst->MoveNext();
            	 }
            	 pRst->Close(); 
            	 
        }
        catch (_com_error &e)

        ::CoUninitialize();
    }

CoInitialize is declared in objbase.h but is superceded by CoInitializeEx. At a minimum you should #define _WIN32_DCOM prior to #including <objbase.h>; you may also have to #include <windows.h> first. If CoInitializeEx doesn't work for you, the older CoInitialize should still work ok.

Hope that helps.

I think Ken is right. Some compilers (namely older mingw's) are retarded about linking COM stuff. Since you are using Borland 6 I doubt this is the cause. But if Ken's doesn't work check the docs on Borland 6.

#import "c:\Program Files\Common Files\System\ADO\msado15.dll" \

Since I haven't tinkered with SQL, I don't know if the same thing holds true there or not, but if this is a C or C++ string, you'll need double backslashes to make that a valid path. \ is an escape sequence when in strings (or single characters) in C++.

You can get away with this in MSVC++ as its just a command to the compiler and is snatched away by the preprocessor

As Ken says, include windows.h .....you might also neede to include ole32.lib for it to link
