DTWAIN Files to Include with your Application

 Top  Previous  Next

The following table summarizes the files you must include on your distribution diskettes to support the DTWAIN DLL functions. Most files in the table are optional.   These files are referred to as 'Redistributables' in the License Agreement.

 

As with all other Windows Dynamic Link Libraries, the files below must be located either in your application's program directory, or in a directory that is accessible by your system's PATH environment variable.  If not, either DTWAIN will fail to load, or one or more of the other support DLL's will fail to load.

 

Note: You may not distribute the DTWAIN header files with your application, and you may not provide software development capabilities in your application that mimic the functions that DTWAIN includes.  Doing so violates the Software License Agreement.

 

For 32-bit applications, the following files must be included for basic DTWAIN functionality.  Basic functionality does not include OCR processing.

 

DTWAIN32.DLL

        or

DTWAIN32U.DLL        

DTWAIN support functions for WIN 32-bit applications.

DTWENG.L32

WIN 32 English resource library.  This contains the error messages necessary for DTWAIN_GetErrorString and other error reporting functions to work correctly.

 

For 64-bit applications, the following files must be included for basic DTWAIN functionality.  Basic functionality does not include OCR processing processing.

 

DTWAIN64.DLL

       or

DTWAIN64U.DLL        

DTWAIN support functions for WIN 64-bit applications.

DTWENG.L64

WIN 64 English resource library.  This contains the error messages necessary for DTWAIN_GetErrorString and other error reporting functions to work correctly.

TWAINDSM.DLL

64-bit TWAIN Data Source Manager.

 

 

Currently DTWAIN's error messages are contained in the resource files DTWENG.L32 and DTWENG.L64.  All strings are contained in the resource file and must be present for many DTWAIN functions to operate successfully.  If English messages are not desired, other languages are available.
