I’m trying to build an app based on Twain.dll and i’m getting this error “Unhandled exception at 0x077F0C90 (HPScanUI.dll) in Twack_32.exe: 0xC0000005: Access violation reading location 0x00000004”.
To emulate my error you could download the twacker-32 from.
Select a source that is not connected to your PC. Click File>Select Source… “Choose one that is not connected to your PC”
Open the Source Manager. Click Special>1 Load/Open SM.
Try to open the source. Click Special>2 Open Source.
After a while it gives the error saying the source is not connected. Expected.
Close the source manager. Click Special>Close/Unload SM.
Now let’s try to open another source(has to be a different one), one that is connected to the PC.
Select the diferent source. Click File>Select Source… “Choose one that is connected to the PC”.
Open the Source Manager. Click Special>1 Load/Open SM.
Try to open the source. Click Special>2 Open Source.
This is where i get my error.
In the case of the twacker-32 the app breaks, you can debug it in the Visual Studio.
And Here it is my error, You can se a print scren of it here.
