Afterwards, you should call
GetLastError()to obtain more info. Did you check what is the exported function name (you may use, for instance, theDependstool)? :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Did you check the exported function name? Do you read the suggestions (mine and of the other folks?)? :)

Check whether scdthndl.dll is loaded, means hLib is having value or it is also 0?

Why didn't you call, as suggested,
GetLastError?If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Then surely StringToCSV is not an exported function from that DLL check the depedency of the DLL, check if StringToCSV is shown in Exported functions.

As I told you before, verify the function is exported.
