Hi All,
I am trying to write a piece of code which will support TWAIN scanning. TWAIN only talks about 2 DLL’s. TWAIN.DLL and TWAIN_32.DLL. How should i make use of these DLL’s in my VB6.0 code? Also, how exactly TWAIN32d.DLL comes into the picture? Is this DLL provided by TWAIN itself?
Thanks.
Hi Pushkar – You only need to worry about twain_32.dll. twain.dll is the old 16-bit TWAIN manager, and I have never heard of twain32d.dll – unless it’s the new 64-bit TWAIN manager? If you want to roll your own TWAIN code, download the TWAIN spec and study it – it describes everything needed to write TWAIN applications (except for being verbose, self-contradictory, vague, and incomplete)(and written for C programmers.) You can make it easier on yourself by googling for a VB interface to TWAIN, there are a number of them floating around the web. Try CodeProject for one place. You could also use my old EZTwain Classic, for which there are VB bindings on the ‘net. I think the newest version actually includes VB6 declarations in the .zip.
