Who knows where did you screw up? Make a code sample (as small as you can) manifesting your problem and post it using "Improve question".

another source of the problem might be an other version of internet explorer the setting for active-x ....

i have got the solution

A Windows Forms based text editor with HTML output[^]

Need to add code in the editor.cs and you can find code in the comments in the above link.

private void theBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
// Existing Code here....

HTMLDocument HTMLDocument =

((HTMLDocumentEvents2_Event)HTMLDocument).onkeypress += new


private bool On_KeyPressEvent(mshtml.IHTMLEventObj e)
if (e.ctrlKey &&
(e.keyCode == 86 || e.keyCode == 118))
return true;

'Try this coding to be added
'This is due to some control conflict between the internet explorer and Windows OS

Private Sub webBrowser1_DocumentCompleted1(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles webBrowser1.DocumentCompleted
If webBrowser1.Version.Major >= 9 Then
doc.designMode = "On"
End If
End Sub

'for C#.NET
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
if (webBrowser1.Version.Major >= 9)
doc.designMode = "On";
