Making the Form immovable

Please help me to make a form immovable without using the movable property.

Thanks

Why without using the MoveAble property?

You could intercept the WM_MOVE commands going to the form using a subclassing tool (see http://www.merrioncomputing.com/Download/index.htm for one called EventVB.dll) but this would be no different than that property.

I believe ithat if you delete the title bar from the form, then you cannot move the form without applying certian tricks. Try it.

Another option:

private Declare Function GetSystemMenu Lib "User" (byval hWnd%, byval bRevert%) as Integer
private Declare Function DeleteMenu Lib "user" (byval hMenu%, byval iditem%, byval wflags%) as Integer

private Const SC_SIZE = &HF000
private Const SC_MOVE = &HF010
private Const MF_BYCOMMAND = &H0

Sub Form_Load()
Dim hWnd%, hMenu%, Success%
hWnd% = me.hWnd
hMenu% = GetSystemMenu(hWnd%, 0)
Success% = deletemenu(hMenu%, SC_SIZE, MF_BYCOMMAND)
Success% = deletemenu(hMenu%, SC_MOVE, MF_BYCOMMAND)
End Sub



Deleting the corresponding item from the system menu prevents the action. This code prevents resizing too.

Hi shree,
It is an exellent solution. But I believe you have to use "user32" instead of "user"

Oh yes, this is an example from the MSDN, and I forgot to "upgrade"

Excellent but its not working in Windows CE

Iam not finding the getSystemMenu api on windows API
Please help me

Hello Shree,

How will I know what values are to be passed for the second parameter of DeleteMenu.

You have been giving &HF000 and &HF010. How will we know what value should be specified?

Thanks

The common System menu items are Move, Size and Close, SC_CLOSE is defined as &hF060. If you want to access other items, then you can use MF_BYPOSITION and specify the position number, 0 for the first menu item. Here is the code that will remove Restore and Move from the system menu:

Code:

---

private Declare Function GetSystemMenu Lib "user32" (byval hWnd%, byval bRevert%) as Integer
private Declare Function DeleteMenu Lib "user32" (byval hMenu%, byval iditem%, byval wflags%) as Integer

private Const SC_SIZE = &HF000
private Const SC_MOVE = &HF010
private Const MF_BYCOMMAND = &H0
private Const MF_BYPOSITION = &H400&

Sub Form_Load()
    Dim hWnd%, hMenu%, Success%
    hWnd% = me.hWnd
    hMenu% = GetSystemMenu(hWnd%, 0)
    'Success% = DeleteMenu(hMenu%, SC_SIZE, MF_BYCOMMAND)
    'Success% = DeleteMenu(hMenu%, SC_MOVE, MF_BYCOMMAND)
    Success% = DeleteMenu(hMenu%, 0, MF_BYPOSITION)
    Success% = DeleteMenu(hMenu%, 0, MF_BYPOSITION)
End Sub

---

Note that I use 0 to remove the Move item too, because after Restore is removed, it is the first item in the menu.
