Version 5.5.5

  • Create versions of DTWAIN DLL that contains full logging and minimal logging. The minimal
    logging versions of DTWAIN results in smaller sizes for the DLL files.

  • Update CAP_PRINTERSTRING to use (by default) TWON_ONEVALUE container on setting capability.

  • Fix issue with determining whether a TWAIN source supports a file system (CAP_FILESYSTEM).

  • Allow internal TWAIN message loop to loop indefinitely until the Source UI is closed. A new
    DTWAIN32.INI and DTWAIN64.INI section ("TwainLoopPeek") will list the TWAIN Product
    Names that will use the new looping mechanism using the Windows API function PeekMessage().
    By default, the looping method used will be the same as previous versions of DTWAIN
    (using the Windows API function GetMessage()).

  • Related to the update of the TWAIN message loop, functions DTWAIN_EnablePeekMessageLoop() and
    DTWAIN_IsPeekMessageLoopEnabled() allows programmatic control of which type of TWAIN message
    loop will be executed with a given TWAIN Source. By default, the message loop uses the
    Windows API function GetMessage() instead of PeekMessage().

  • Ensure setting string capabilities uses ANSI strings.

  • Change parameters to certain API functions from LONG to DWORD to delineate signed versus unsigned values.
    The size in bits of LONG and DWORD are the same, the only difference is that DWORD is an unsigned 32-bit integer
    while LONG is a signed 32-bit integer.

  • Add Japanese, Traditional Chinese, and Greek text resources.

  • All lines in the logs generated with DTWAIN_SetTwainLog() have timestamps (with the
    by-product of this change being that all the log lines are properly indented).

  • DTWDEMO32 and DTWDEMO64 programs now do not require VCRUNTIME140.DLL to be present.

  • On return of DTWAIN functions that handle pointers as input, the values that the pointers
    will point to are now logged (only available with full logging versions of DTWAIN DLL).

  • Added missing constants to twaininfo.txt

  • DTWAIN_SelectDefaultSource() will now only make a call to the TWAIN DSM if the DSM is version 2
    or greater (TWAINDSM.DLL).

  • DTWAIN_GetSourceDetails() now correctly reports custom capabilities that are also extended capabilities.
