Firstly, if you're using GetProcAddress the function should be exported from the DLL. Check with something like depends[^].
#import is for type libraries. Using this implies that the method is exported using COM, in which case GetProcAddress will not work.

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

Why different names?

Afterwards, you should call GetLastError() to obtain more info.
Did you check what is the exported function name (you may use, for instance, the Depends tool)?

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

Why didn't you call, as suggested, GetLastError ?

the other comments are fully right to call the dll.
But for string parameter you should use BSTR type. An article with basic explanations:

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

hi
hlib have value...GetProcAddress() only Null coming
please give me any suggestions....
|
|
|
|

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.

Hi,
How to remove menu of a running application through another application?
|
|
|
|

I am trying to establish TCP/IP communication between DSP board(that runs Code Composer Studio, an IDE to compile and run C code) and host PC(that runs VC++ application)
While sending the data from CCS to VC, sometimes "Retransmission Timeout" error occurs, and at other instance "Persist Timeout" occurs, after this timeout the transmission stops.
How to address these errors in VC++ MFC code. (CAsyncSocket class and the member functions are used for reception of data at VC++ end)
