mdi-list problem

[git]

Hello all,

 

i"ve written an application in visual Studio .Net (visual basic) but encounterd some sort of bug...

 

Please look into the following:

 

Situation

------------------------------------------------

.net framework 1.1

studio.net -> visualbasic

Main-form contains:

Mdi-container property = true

menu-items

one menu-item contains this code under the click event and launches a mdi-child named Offerte_form:

 

Dim NewMDIChild As New Offerte_form()

Set the Parent Form of the Child window.

NewMDIChild.MdiParent = Me

Display the new form.

NewMDIChild.Show()

[/Code]

 

Offerte_form contains:

menu-items

textbox (just as reference)

one menu item contains:

name: &Windows

MDI-list property = true

 

Problem

----------------------------------------------

Now the following problem arises:

when clicking the &windows when the MDI-Childform is in normal mode (e.g. not fully maximized) the MDI-list is generated properly.

But when i maximize the MDI-Childform and click on &windows agian the fist time it will not show the list. Clicking the second time on the &window will result in the list.

 

Did i forget something to set or is this a bug in studio.net?

Can you post your project? I cannot duplicate this in either .NET 1.0 or .NET 1.1.

MDI-List example

 

here by the example.

 

if:

the mdi-childform is normal: no problem... mdilist=ok

the mdi-childform is maximized: problem!!... mdilist=not ok needs 2 clicks to display...

Weird... I actually get a NullReferenceException from somewhere in the framework when I maximize them after I've already looked at the Windows menu. I'm guessing this is a bug you should submit to Microsoft.

[Nerseus]

I didn't get the NullReference, but I do get the Windows menu problem you're talking about. It's as if the Windows menu "eats" the first click - just doesn't respond.

 

By the way, it only appears to happen if your child forms have menus. My original sample project didn't have any menus on the child forms. If you take off the main menus from your child forms you'll notice the Windows menu working as expected.

 

Oddly enough, the select and popup events fire on the window marked as the MdiList, it just doesn't show the list. You might be able to do that manually to get around the bug for now.

I've also noticed that the mdi-list creates a memmory-leak. with or without the menu's in the 2 other forms..

 

i think i will submit this problem to microsoft.. after i did a complete reinstall of XP & .Net & Studio just to be sure it's not my config...

[update]

i've also found out by change that the first click on this menu item will result in a click on the menu-item on the right.

 

problem send to microsoft....
