Hello, Erdogan Uguz!

You can use COMObject to create an instance of WIA COM object or TWAIN add-in. Then you save a file to the temporary directory, read and save it in the ValueStorage attribute in the infobase.
Here are examples for you to start:

Code
ScanDialog = New COMObject("WIA.CommonDialog");
ScanDialog.ShowAcquireImage();

Code
TwainAddIn = New("AddIn.twain.AddInNativeExtension");
TwainAddIn.BeginScan(...);


Details on methods and properties of COM objects you can find in documentation of their vendors.

You might find useful the list of methods of the TWAIN component that is built into 1C:Small Business. See the TwainComponent common template usage.

Hope, this helps.

I clicked on the link you wrote. I looked. Frankly, I do not understand anything.It seemed a bit confused. We are developing software using C # and Java. We use Twain and WIA. But here I do not understand how to use. I could not find in the Help guide. Is there a more detailed example?
- To list the scanner.
- Select the scanner.
- Get the picture from the scanner and to transfer the image box.
