Try storing the return value of resources.GetObject(...) to see what is being returned. It might help determining what's going on.

Problems with ActiveX - DOM documentElement change

scarabxx — Thu, 18 Aug 2005 09:44:51 GMT

Hello

I have an ActiveX (Basically an UserControl from Window.Forms
namespace)written C# (.NET 1.1) which is used in MS InfoPath for displaying
images.

The problem is that "sometimes" when constructor of my User control is called
I got an Exception (Specified cast is not valid).

The "sometimes" - I mean: the refresh in MS InfoPath caused by changing of
DOM where my ActiveX is binded. In normal cases like opening document the
ActiveX works perfect - no exception (see 2.).

My UserControl had set "Localizable" property to true so settings of
controls in my UserControl comes from embedded resources (See 1 and 2.):

1) //(from InitializeComponet method)
System.Resources.ResourceManager resources = new
System.Resources.ResourceManager(typeof(MyUserControl));

2) this.uiPictureBox.Location =
((System.Drawing.Point)(resources.GetObject("uiPictureBox.Location")));
//This is where Exception is thrown

The problem can NOT be in resource file because ActiveX live under normal
condition OK, but I strongly suspect ResourceManager, that under some (for me
unknown) conditions behaves that it has resources loaded, but attemt to cast
retrieved resources throws an Exception.

Thank You for Your reply
