Hi,
I would like to develop a screen for configuring the scanner properties. Is there any controls that i can use it for configuring scanners instead of creating my own control.

Regards,
Sara

Sara,
I'm not sure that I understand what you mean exactly but you can show the device driver dialog without scanning by calling the TwainSession.ShowTemplateDialog Method (if you are using .NET objects). If you are using other programming interface, please specify.

If you mean something else, please provide with more details.

Sara,
We have functions that allow you to control scanning devices that have a standard Twain driver or WIA driver.
Are you using such a device?

If your scanner's driver supports the capabilities you mentioned, you should be able to use our toolkit to control them.
Which programming language(s) are you considering using?

Sara,
I modified the WPF demo to add TWAIN functionality to it, and it worked.

Just modify the TwainSession.Startup() method in the example in the help topic "Acquire Method" in our .NET help file. It should be like this:
acq_session.Startup(null, "LEAD Technologies, Inc.", "LEAD Twain .NET", "Version 16.5", "LEADTools Twain test sample", TwainStartupFlags.InitializeMultithreaded);

I'm attaching the modified project. You can try the scanning feature when you run the demo from menu Help->About..

The better way to startup the Twain session in a WPF application is to use WPFs libraries to get an IWin32Window
object for the WPF window.  Here's an example from CodeProject that shows how to do this:

http://www.codeproject.com/KB/WPF/MessageBox.aspx

I've also attached a small sample project in C# 2008 that implements it.
