That's quite far fetched, the bug applies to VB 5. But on the other hand, you'll never know...

Solution 6

Try this:

C#

Form2.ShowDialog(Me);

Solution 2

Sounds like you have drawn controls on the MDI parent. If that is true, you should never do that. Controls are always placed on MDI children excluding status bar, menu bar etc.

How about if i want to do that??!! Isn't any way?

Wendelius 28-Dec-11 15:55pm

If I recall correctly, no. Basically you could hide the controls when a child form is shown but still you would have some trouble. What if part of the control drawn on MDIParent should be visible and so on.

If these controls on the MDIParent's area which is reserved for child forms is the problem, I think you should consider redesigning the UI.

Look, listen to a good friendly advice: stop torturing yourself and chasing out your users with that MDI nonsense. Nearly everyone discourages it, and Microsoft worked hard to phase this thing out. Finally, MDI was not included in WPF even though it remains in System.Windows.Forms, presumably for compatibility with legacy code, but highly discouraged even by Microsoft where this concept was created.

There are many robust conceptions; the simplest one is the tabbed UI based on TabControl.

Please see:

Good luck,

MDI is perfectly viable. Just because Microsoft isn't behind it anymore doesn't mean squat. Look at all the other stuff they've abandoned - Silverlight - WinForms - C++ - unmanaged development...

Sergey Alexandrovich Kryukov 30-Dec-11 10:30am

I agree with other stuff and partially agree with MDI -- it is viable and applicable. Formally. But in practice, I cannot see any single reason to use it, ever. Harder to develop (if one needs minimal flexibility), awkward to use.

I never mind using "old" technologies -- they can be better then "new" and "trendy", and I almost hate the idea of using anything "cool", but there are considerations other than that. MDI was bad at the moment of its creation.

Also, I don't see that Slverlight, Forms, unmanaged C++ were abandoned...

Never mind, this is an old question that got resurrected by some idiot.

Sergey Alexandrovich Kryukov 17-Apr-15 19:45pm

No problem, but I don't think "resurrection" of old post is always idiotic. Truth does not have expiration date on it. And MDI is not completely in the trash bins. If someones find some mistakes in one's own post, it's better to fix it than not to. (I don't mean this particular post). I don't know why there is so much buzz about "old".
Thank you.

I know that, but Solution 6 is what did it. Take a peek at that and....yeah.

Sergey Alexandrovich Kryukov 17-Apr-15 20:06pm

Sure. But may be this particular solution, #6, was a good idea. :-)

On which planet? :)

Sergey Alexandrovich Kryukov 17-Apr-15 22:55pm

The same planet where it recently gone. :-)
Jokes aside, we don't know what the inquirer really wanted, so the idea to just show modal form could be it.

I know what he was doing and why it didn't work. The MdiClient control, by default, is always Docked Full and sits last in the control Z-Order. You have to jump through some hoops to grab the MdiClient control, undock it, move it around, or put it into another container, or a TableLayoutPanel, or whatever.

It's a bit of a pin, but... I really never had a use for the stupid MDI thing. It's not like I wanted to ever write a multi-document Notepad! :)

Sergey Alexandrovich Kryukov 17-Apr-15 23:10pm

I used MDI in the past, and even did tricky things such as the background images on the MDI client (which is not children; it is an internal client part of MDI parent, the background for children). And this is the exact reason why I recommend never ever get into it: I just know how much this stupid thing rotten. And of course, it does irritates the users.
