Load .obj file in WPF - Load by Code - Dynamically!

3-Mar-09 0:25

You will have to databind the IsEnabled Property of ListBox item to a CLR property in the databound object. The Visual tree is not accessible easily once you use Data binding. Once you databind the IsEnabled property to a CLR property then setting the CLR property will automatically enable\disable the ListBox item.

Hope I made sense Smile | :)

You cannot directly use a WPF control in WinForms. You will need to use an ElementHost[^]

e.g.

ElementHost elhost = new ElementHost();<br />
      elhost.Size = new Size(110, 60);<br />
      elhost.Location = new Point(45,35);<br />
<br />
      MyWPFControl wpfctl = new MyWPFControl();<br />
      elhost.Child = wpfctl;<br />
<br />
      myForm.Controls.Add(elhost);

See here[^]

because you are sending it upwards only.

I don't think the logic you are using will work for Pan. I might be wrong.See This[^] and this[^].

WPF is supported from Win XP onwards. . From the site,
"When the classes are used on Windows XP, they will automatically fall back to the old style dialog; this is also true for the VistaFolderBrowserDialog on WPF; that class provides a complete implementation of a folder browser dialog for WPF, old as well as new style."

Silverlight MediaElement to play video

4-Mar-09 9:52

Busted!

Yeah, WPF and Silverlight. I scrapped and converted ALL my MFC UI stuff
to C#/WPF starting about a year ago.

I still use C++ but only for device I/O and occasionally performance-critical
native code.

I spend most of my newsgroup time in the MS Silverlight forums these days.

A simple google search would have turned up this[^] article. If you want to be a professional developer, you have to have the ability to do your own research first - that way you don't waste time waiting for somebody to answer your question.

I agree. But sometimes for a person who isn't English , "what he should search (key words)" it's an issue

I searched for zoom image wpf. The keywords were all in his question, so this shouldn't have been a problem.

AVI files aren't currently supported for MediaElement AFAIK.

Try converting the AVI to WMV Smile | :)

Also, if you're going to use a relative URI like that, make sure the
media file is in the same folder as the contents of the Silverlight app's
XAP.
