How do you know if a combination of a path and filename is valid ? I don't want to know if it is an actual existing file but only if it's valid (does not contain any invalid caracters). Also, I do not want to create a file on the disk to know if I'll receive an invalid filename error. So, how can I know if a path + filename combination has a valid syntax ? (example: "C:\folder name\file name.ext" is valid, "C:\folder name\file&?n!.ext" is invalid) I'm using C++ only (no MFC, etc). Thanks a lot ! =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= J.-C.

Is there a way to enable/disable a button whitout using MFC ? I am not really familliar with this type of operation. I've done it successfully for edit control : // Enable ::SendDlgItemMessage(hwndDlg, IDC_KEYPAIRNEWFILENAME, WM_ENABLE, TRUE, 0); // Disable ::SendDlgItemMessage(hwndDlg, IDC_KEYPAIRNEWFILENAME, WM_ENABLE, FALSE, 0); and was expectiong something similar for buttons but everything I tried was unsuccessfull. Thanks. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= J.-C. Gauthier - http://www.grandmenhir.com/

I have a problem converting a CComBSTR to LPCTSTR with CW2CT. Eveything works fine until my CComBSTR gets around 64 caracters... then the result of the convertion is a long "corrupted" string: "îþîþîþîþîþîþîþîþîþîþîþîþîþîþîþ...." Please help me ! :(( ----- See comments between /* */ for more info -----
