My application work fine if I open my delimited file first in WordPad and then copy paste to my application but not if I open the file in NotePad. I would like to understand what is the difference 'structure wise' between opening a delimited file in WordPad vice NotePad. Thanks, Fred ...Show All

• Silverlight (formerly WPF/E) What controls?

  Does WPF/E contain any controls, like button, text box, combo I didn't see any in the SDK documentation. I also didn't see anything that looked like a Table, or FlowPanel. If not then it seems this technology can't really be used to design an application that runs inside of a web browser. You could probably build a button via rectangle objects and click events but I don't know how you'd build a text input control. You could create a hodgepodge application with some HTML controls and some WPF/E graphics but I doubt this would be a compelling user experience; you'd suffer from the inconsistent rendering of CSS/HTML across browsers. It looks to me like the vision for WPF/E has been scaled back - no minimal C# and no controls. ...Show All
