Hi:
Somehow I found an example code (a Wrapper, now I understand) and Im able with this code to Open, Close, even write to a particular Excel Cell [Im using Visual C++ 2010 EXPRESS EDITION]; however so far I cannot READ from an Excel Cell.
If you are familiar with this AutoWrap (or formerly, OLEMethod) function, I would appreciate it if you could suggest a procedure to READ from a particular cell in EXCEL (all the hurdles to Open, Activate certain sheet in a file, and even WRITE to a Cell have been succesfully overcame).
Here is part of the code...
Thank you in advance. Please, just comments from people well aware of this code. Thanks again!
PS. AutoWrap function not shown (however you can notice function calls to AutoWrap...the lines below are just an example). Suppose also I have activated the worksheet needed...everything ready to READ from an Excel File...HOW COULD I INSTRUCT THE AUTOWRAP FUNCTION TO READ A CELL (Is it a
DISPATCH_PROPERTYPUT/ or GET or just a DISPATCH_METHOD the one required while calling the AutoWrap function)?
