How do I prevent a form from being resized by the

问题:

I have a form that needs to be maximized in VB.net. I don't want the user to be able to change its size or move it around. How can I do this?

回答1:

Set the highlighted properties. Set MaximimSize and MinimizeSize properties the same size

回答2:

//Set fixed border
yourForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Fixed3D

//Set the state of your form to maximized       
yourForm.WindowState = FormWindowState.Maximized

//Disable the minimize box and the maximize box
yourForm.MinimizeBox = False
yourForm.MaximizeBox = False

回答3:

Set the window start style as maximized. Then, hide the minimize and maximize buttons.

回答4:

To prevent users from resizing, set the FormBoderStyle to Fixed3D or FixedDialog from properties window or from code

frmYour.BorderStyle = System.WinForms.FormBorderStyle.Fixed3D

And set the WindowState property to Maximized, set the MaximizeBox and MinimizeBox properties to false.

To prevent the user from moving around, override WndProc

Protected Overrides Sub WndProc(ByRef m As Message)
        Const WM_NCLBUTTONDOWN As Integer = 161
        Const WM_SYSCOMMAND As Integer = 274
        Const HTCAPTION As Integer = 2
        Const SC_MOVE As Integer = 61456

        If (m.Msg = WM_SYSCOMMAND) And (m.WParam.ToInt32() = SC_MOVE) Then
            Return
        End If

        If (m.Msg = WM_NCLBUTTONDOWN) And (m.WParam.ToInt32() = HTCAPTION) Then
            Return
        End If

        MyBase.WndProc(m)
    End Sub

Add some code to the Form Load event:

me.maximumsize = new size(Width, Height)
me.minimumsize = me.maximumsize
me.maximizebox = false
me.minimizebox = false

Example: For a Form height and width of 50 pixels each:

me.maximumsize = new size(50, 50)
me.minimumsize = me.maximumsize
me.maximizebox = false
me.minimizebox = false

Note that setting maximumsize and minimumsize to the same size as shown here prevents resizing the Form.

回答6:

Set FormBorderStyle to 'FixedDialog'

回答7:

You can remove the UI to control this with:

frmYour.MinimizeBox = False
frmYour.MaximizeBox = False

回答8:

Set the min and max size of form to same numbers. Do not show min and max buttons.

回答9:

Just change these settings in the Solution Explorer.

MaximizeBox = False
MinimizeBox = False 

The other things such as ControlBox, Locked, and FormBorderStyle are extra.

回答10:

There is an option in vb.net that lets you do all this.

The user wont be able to re-size the form or move it around, although there are other ways, this I think is the best.
