MDIform

[veryjonny]

How do I stop the user from double-clicking the title bar of the MDIform and changing it to restore mode.

I have Used some API's (Copied it from somewhere - my knowledge of API's = NILL) to disable the restore/max button of the MDI form.

I open the MDI form in VbMaximised mode and want it that it shd remain either MAXimised or minismised but NOT in the "restored"
position.

I am not sure but can you check the windowstate property in resize event of the form and set it accordingly

[veryjonny]

But that causes a jeck in the form - which doesnt look very appealing

for that you can lock the screen first, perform the resizing and then unlock again.

this code is from www.vbworld.com

Usage
 
LockWindow(Form1.hWnd)
 
'Do updating here
 
UnloadWindow
Code
 
Declare Function LockWindowUpdate Lib "user32" _
    (ByVal hWnd As Long) As Long
 
Public Sub LockWindow(hWnd As Long)
    LockWindowUpdate hWnd
End Sub
 
Public Sub UnlockWindow()
    LockWindowUpdate 0
End Sub

I put your functions :

in the mdiform1 resize event but still it becomes smaller and becomes max again - which actually would happen without the API.

Perphaps I am not using it correctly ,Pls tell me how to use it

Thanks

i just checked the function.
resize event occurs after the resizing form. that is why it is getting minimized.
screen should be locked before getting minimized.
i think you should lock the screen as soon as it is displayed. and then detect any mouseevents to do rest of work i.e unlock it after performing some updation...If this is okay with application of your form.
