Poltergeists?

[Alex]

Am I going crazy?

In my Word COM add-in (in C#), I present a Windows Form. There, I have a radio buttons on a tab page that somehow gets a click sent to it when I switch tabs, even though I didn't click it.

This messes up the application.

Please help!


The call stack shows:

Hi Alex,

Based on my test I can not reproduce the problem.
Here is my reproduce code.
[1 Show a Form]
public void OnConnection(object application,
Extensibility.ext_ConnectMode connectMode, object addInInst, ref
System.Array custom)
{
applicationObject = application;
addInInstance = addInInst;
Form_Tab ft = new Form_Tab();
ft.Show();
}

[2 on the form I have two tab page, each have a radiobutton, and handle
then as below.
private void radioButton1_CheckedChanged(object sender, System.EventArgs
e)
{
System.Diagnostics.Debug.WriteLine("radioButton1_CheckedChanged");
}

private void radioButton2_CheckedChanged(object sender, System.EventArgs
e)
{
System.Diagnostics.Debug.WriteLine("radioButton2_CheckedChanged");
}

[3 run the winword and the form will invoke, but the two checkedchanged
will not fire when I switch the tabpage.
It will fire only when I click on the radiobutton to change the check state.

You may have a try.
Also can you provide a reproduce sample together with the reproduce steps
to me.
You may reach me via removing the "online" from my email address.

Thanks for your understanding!
