Problem with name of file #85

Closed HezinTUKE closed 2 months ago

HezinTUKE commented 8 months ago

Hello, after scanning the source ( DTWAIN_AcquireFile ) it adds DTWAIN_SysDestroy to the file name and at the end I get the file name FILE.tifDTWAIN_SysDestroy

More than likely it is a bug in your program (maybe you are using a non-null-terminated string when a null-terminated string is expected?). Please post the program.

DTWAIN_AcquireFile requires a null-terminated string as the file name. Given the issue you are having, I am getting the suspicion that the name you are giving DTWAIN_AcquireFile is not null-terminated. Whatever stray characters that appear after the "good" string is being picked up, all due to the null that's missing.

If you were to produce a full TWAIN log and inspected the DTWAIN_AcquireFile call in the call stack, it will show that the string you are passing is faulty, thus not an error in DTWAIN.

Closing, as this issue is in all likelihood due to passing a string that is not null-terminated string to DTWAIN_AcquireFile.
