DTWAIN Error Constants

 Top  Previous  Next

The DTWAIN_GetLastError function returns the last DTWAIN error that occurred.  The following values are the various DTWAIN specific error codes.

 

The actual numerical values of these return codes can be found in the DTWAINDEFS.H header file.  Note that the numerical values may change from one version of DTWAIN to another, so it is best to rely on the names below, and not the actual error number.  To retrieve the error as a string, call DTWAIN_GetErrorString (note that you need the correct DTW*.L32 language DLL installed to see any of the error messages when calling DTWAIN_GetErrorString)
