I had an vb.net desktop application which uses MDIForm.In that application all the child formes are in maximized state.When i am open any form and minimized,then that child form gets minimized and no problem for for the first time.Then i have to maximize and minimize the same form then there is an automatic vertical scroll appears on MDI Form.And also the location of child form goes downwards.Similar Problem happends for other forms also.

I am planning to have a vb.net windows form applocation that has a main mdi ( contains menu strip + panels all over the mdi )
the problems is when a child form is shown , and when minimizing the child form it disappears behind the main mdi.
any ideas how to solve this without changing the size of the child form
MDI Issue
I am trying to make a transparent control with child controls that are visible and opaque.
I have added a panel control to the main form via code in the form load event. In this I am adding five buttons as child controls like: panel.controls.add(). To all of these, I have set backcolor=color.transparent.
When I run this program, the button background shows the background of the next button in the panel. If I open a child form, then I can see labels on the child form as the background of the panel.
I want to make container panel control completely transparent, so I can see the main form through it. How can this be achieved?
When the form loads, you can see neighbor buttons behind the actual buttons
"Perform Check" is a label on a child form which I opened right before taking this picture.
: "Check Cases and Combinations" is a button on a child form which I opened right before I took this picture.
How can I make it truly transparent? Why doesn't the background of the panel control refresh with the main form background? The panel sort of "keeps" whatever happens on the main form and shows it as a background.
I found out there some issues with setting controls that are transparent and on top of other controls in the main form. They take the background of the container form, whether or not there is any control in between. I used WPF form instead of the panel and it worked perfectly.
anybody use .NET MDI containers much?
I've got an MDI Parent form that creates a bunch of smaller MDI child forms within it after a user clicks a toolbar. The child forms are all set to have the maximize button, and when clicked, they fill the parent container. But here's my problem:
Once you maximize one child, all of the subsequent child forms you open are maximized as well. Likewise, if you have several child forms open and maximized, clicking the shrink window button shrinks all of them.
Anyway to get around this?
Thanks,

Sounds like this could break alot of things you would not want to break

you might want to try a different approach
One would imagine that clicking anywhere within the MDI Child form (or on any control) will focus that form. But in my application I can only focus a MDI child by clicking on its titlebar, which is an abnormal behavior on the part of the user. My forms are filled with either controls or panels so I don't have the luxury of just "clicking on the form." But clicking anywhere within it should focus it.
I haven't been able to find a solution to this problem although it seems others are having it as well.
I figured it out. If you are setting the child form mdiParent property after you are calling Form.Show then it messes up the focus of all the child forms.
When I set mdiParent property of the form first and then call .Show(), everything works perfectly as expected.
I have a MDI parent that opens another form like this:
Dim frm As New Form1
frm.ShowDialog(Me)
That form has a button that, when clicked, does this:
CreateObject("Shell.Application").ToggleDesktop()
The button operates as expected (showing the desktop) most of the time but occasionally does not minimize the MDI parent. All the other windows, including the form above get minimized every time.
Why is this happening, and how do I fix it?
Instead of trying to allow a form shown with ShowDialog I changed the angle from which I'm approaching. I'll show the form with Show and assign the MdiParent and just fake the modality of the form instead. The fake modal will disable all other parts of the MDI parent except the system buttons in the title bar. If the user attempts to close the MDI parent, the "modal" window will beep once and blink the title bar a bit.
