Running DLL Twice

[kpassaur]

I have a dll that I load and it runs. I end it with libfree naturally and when I go to run it again I get an error unless I exit from the script.

Below are the lines I use:

Let>twainsave_key=5B7EAE51-5A1E-C4E5-6016-NOTREALKEY21C3
Let>twainsave_key_start={
Let>twainsave_key_end=}
Let>twainsave_fullkey=twainsave_key_start
concat>twainsave_fullkey,twainsave_key
concat>twainsave_fullkey,twainsave_key_end

Let>command=-details "%scannersettingsdir%\details.txt"
LibLoad>%SYS_DIR%\twainsave.dll,hDll
LibFunc>hDll,TS_X,ret1,twainsave_fullkey
LibFunc>hDll,TS_Command,ret2,%command%
LibFree>hDll

Any ideas? Does it have to do with the buffer and if so how would I go about settting it?

Thanks

What happens if you LibLoad> at the beginning of the script and LibFree> at the end of the script rather than loading and freeing multiple times?

I just did as you mentioned and it seems to work. Much better than my work around which was to disable the button once it was run.
