I am using Leadtools Document Suite 14.  I am try to set up a twain session in .NET 2005 Beta2(C#), but keep getting an error when I call the method SelectSource().

I get the following error:

Twain Failure due to unknown cause.

Is there a compatibility issue with 2005 Beta 2?  Seems to work fine with 2003.

Hello,

 

You will need to make sure that you specify to use v1.1 of the .NET framework to use LEADTOOLS components.

Microsoft has changed the syntax of C++ in v2 of the framework, meaning that we will have to rewrite LEADTOOLS to port it to v2.

I am using VS2005, and I am having trouble using twain. How do you specify to use v1.1 of the .NET framework?

Hello,

You can specify to use v1.1 of the .Net framework as shown below:
- Open you project on VS2005.
- Select the "Project">"Properties" Menu (Your project Property pages dialog appears to you).
- Within the dialog, select "Build" property under the "Common Properties" node from the list.
- Now, Press the "Change" button and set the .Net Framework Version to "Microsoft .Net Framework v1.1"

Thanks,
