.Net 2.0 - WebBrowser control embedded in IE causes problems


L. Chernov


I am trying to work with .Net 2005 WebBrowser object,
and put it on a "Windows control library" (embedded in a user control class)
and then I
am executing it from an ASP.Net webform(with IE6) with the following object
<OBJECT id="ModPkiObj" height="550" width="800"
name="ModPkiObj" VIEWASTEXT>

And I get the following error:

System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'WebBrowser'.
at System.Windows.Forms.WebBrowser.get_AxIWebBrowser2()
at System.Windows.Forms.WebBrowser.PerformNavigate2(Object& URL, Object&
flags, Object& targetFrameName, Object& postData, Object& headers)
at System.Windows.Forms.WebBrowser.PerformNavigateHelper(String
urlString, Boolean newWindow, String targetFrameName, Byte[] postData,
String headers)

EventArgs e)

button, Int32 clicks)

at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg,
IntPtr wparam, IntPtr lparam)

Remark: When using this control library class from a winform container I
dont get this bug.

Thank You
