TWAIN trouble

Hi,

Does any of you have any experience with EZTWAIN. I'm encountering the following problem.

The function 'LoadLibrary( "c:\\windows\\twain.dll" ) return 0 (zero) and the library is not loaded. Other (16 bit) programs (like IPhoto Plus) have no problem 'aquiring' the TWAIN library (in this case with SNAPPY).

I'm using EZTWAIN from ftp.twain.org but when I debug the source. The LoadLibrary causes the problems. All the files are in the right directories, but something seems to go wrong. Any suggestions.

(I'm still developing 16 bit programs because the majority of our customers are still using windows 3.11).

System:
      Pentium       150 Mhz
      Memory      32 Mb
      
Operating System:
      Windows 95

Compiler:
      Borland C++ v4.5 and v5.01

Paul Sinnema :-)

Commented:
Run the debug kernel.  When I worked at MS on Win 3.1 KRNL386, I added lots of debug_outs to let you know why a load fails.

Error 0 means "something bad happened", typically out of memory, but it could also be a corrupt file, or can't find a DLL dependency, etc.

Dump out the dependency list of your copy of TWAIN.DLL, it may depend on other helper DLLs in other directories.  (I think Borland has a nice dump utility.)

Try loading another DLL in the same directory, just to make sure you don't have problems in general loading DLLs.
