I am trying to make a Form Non-Movable. How can I do this??? I have already made it non-resizable, now I just need to make it non-movable.
Thanks in advance!

Weird enough, this is ridiculously simple to achieve:

Add the following code to the the form constructor:

C#

public NonMovableForm() {
   InitializeComponent();
   //add this:
   this.ShowInTaskbar = false;
   this.ControlBox = false;
   this.Text = null;
} //NonMovableForm

If you really need it, create a fake control imitating a title bar with Close button on it (or not) and dock it to the top of the form.
Do not implement form dragging. :-)
Get ready to receive multiple complaints from the users.
PROFIT? I'm not sure — see the item above.

Anyway, the problem is solved. Decide for yourself if you really want it.

Hello SA again! :) Hmm.. I just tried that but it did not work..

You said that you already manged to make it non resizeable... and the above code do all the remainding step to prevent the form to be moved. If you have find a way to still move the form, tell us how.

Without caption, task-bar button and system menu I cannot see how you could move it anyway.

Andrew, please tell me what do you see. Do you see that the title bar disappeared? It solves the problem of non-movable because there is no a way to move.

Add also this.FormBorderStyle = FormBorderStyle.FixedDialog; (or any other non-moveable border style). This will prevent the form from being "moved" by resizing it... Otherwise, if all properties indicated in step 1 are set as indicated, it is not possible to move the form.

Sure, I ignored it only because OP said non-resizeable is already done.

Here it is. Just convert C# to VB.NET.

Did you check it? It will certainly prevent moving via SYS_COMMAND, but how about dragging by a mouse? At lease you should remove a system icon box.

I've tested my solution, please see.

I always test the code proposed.
This is VB.NET variant and the window is "non-movable" (for whatever reason it is needed):

Protected Overrides Sub WndProc(ByRef m As Message)
Const WM_SYSCOMMAND As Integer = &H112
Const SC_MOVE As Integer = &Hf010

Select Case m.Msg
Case WM_SYSCOMMAND
Dim command As Integer = m.WParam.ToInt32() And &Hfff0
If command = SC_MOVE Then
Return
End If
Exit Select
End Select
MyBase.WndProc(m)
End Sub

Solution 5

I am using java caz i have once implemented it in inventory system application;

you have to add Componentlistener to the frame and code specific location you want to set.

example

frame.addComponentListener(new ComponentListener(){
@Override
public void componentMoved(ComponentEvent e) {

frame.setSize(200,300);
frame.setAlwaysOnTop(true);
}

});
frame.setLocation(setSize(200,300));
//frame.set

The question was asked and answered over 2 years ago.
VB.NET does not have a Componentlistener so even if the question were not ancient, your solution would be irrelevant.

Don't do it...

Move the windows where you want it to appears. If you really want it, then perhaps you could ensure that if the user move the windows it stay visible on one monitor.

It can be frustrating to your user not to be able to move a windows. For example, the user might change his monitor resolution, have multiple monitor (he might then prefer to show that windows on another monitor). The user might use one of its screen for a full screen application and then prefer to have your application on another monitor.

By the way, it you prevent your windows from being moved, it might be moved anyway by the system when changing the resoution (depending on how you do it).

A user can install some third party product or write an utility to move the windows anyway.

You will have to correctly handle thing like changes of the resolutions, monitors, desktop area (for example if the user drag the taskbar on another side that the default).

Another application might have decided to do the same as you and thus overlap your windows without the user being able to do anything about it.

Windows was designed that way with a purpoose. Those that do applications that violate the rules might be hated by some.

Doing that might force you to have unsafe code in your application. If the application could underwise be compiled as a safe application, this would be a very bad thing...
