How to access a scanner via TWAIN.

[byron.hopp]

Anybody have any recommendations for accessing a scanner via TWAIN with FiveWin?

I'm using eztw32.dll.

DLL STATIC FUNCTION TWAIN_ACQUIRETOFILENAME( hWnd AS LONG, cFile AS LPSTR ) AS LONG;

Byron, did you try my sample?

Yes I made a quick attempt, but I could not get it to link.

Where do I find SaveImg(), is this Harbour, Fivewin, or from the DLL.
If it is from the DLL do I need to create a declare statement for it as well.

My xHarbour is kind of old: (like me)
xHarbour Compiler build 0.99.61 (SimpLex)

My FiveWin:
7.01

Please try without SaveImg(). If you are really interested I will post the function here.

Works without SaveImg().
Is there more functionality of the EzTw32.dll.
Like x and y resolution and so one.
do you possibility have a prg with all of the "DLL Static Function" declare statements?
It seems there should be a way to hide the UI of the twain provider, and set the resolution.

No matter what, it works, thanks...

You might try this example application.
You might need to create your own import .lib
