c# - Form.ShowDialog() or Form.ShowDialog(this)?

Question

I heard that if I call form.ShowDialog() without specifying the owner, then there can be a case when I will not see the dialog form on screen (it will be hidden with other windows). Is it true? I used ShowDialog() without specifying the owner hundreds of times and I never had any problems with that.

Can you please explain in which situation I could get the described problem?

UPDATE:

Well, I did many experiments and I couldn't get any real unexpected problems with using ShowDialog() (without specifying the owner).

So I think it's just rumors that ShowDialog() can lead to problems. If you don't agree - give me a code sample please that leads to a problem.

Answer 1

One annoyance I found with ShowDialog() vs ShowDialog(this).

Run the TestApp, show the newform.ShowDialog(), click "show Desktop" on your taskbar or Quick launch toolbar, click on the TestApp on the taskbar. It shows the Mainform. You have to do an Alt-Tab to get to your newform.

Run the TestApp, show the newform.ShowDialog(this), click "show Desktop" on your taskbar or Quick launch toolbar, click on the TestApp on the taskbar. It shows the newform on top.
