Maximize Form BUT maintain original width...

[Mindcrime]

Hi Guys and gals

Been a long time. Right I need to maximize a form but only by height and not width.

For example, if the form is sitting in the middle of the screen and it's width and height are 33% of the screens width and height, then when the user clicks the maximize button the form resizes so that its width is still 33% of the screen width, but the forms height is now 100% of the screens height.

The percentages aren't important. The important thing is that the width is maintained.

Also the Maximized button (top right of the form) needs to indicate its been maxmized and once clikced it resizes back to the original size (33% width and height in the example).

There something nice and easy for a saturday afternoon.

I'd use subclassing to define a maximum width of the form. I think this will take care of the maximize button behaving like you want it to also, but will have to test it first.

Lots of code on here and elsewhere on the internet for "subclassing max form width" etc. One example:

simplest way

Me.Height = Screen.Height - 500
    
    Me.Top = 0

here the 500 is the height of the task bar given manually. This is for my screen res. There should be a way to capture the task bar widow handle and get its height. Thats bit hard but possible.

Cheers ZeeZee, that would work fine for the first line of my post

Thanks, but for your second part , you would need to use what DigiRev has given.

In that, you can keep the form width same and when maximizing, get (screen height - Taskbar Height) as form height.

This code does it

Option Explicit
Private Const ABM_GETTASKBARPOS = &H5

Private Type RECT
    Left As Long
    Top As Long
    Right As Long
    Bottom As Long
End Type

Private Type APPBARDATA
    cbSize As Long
    hwnd As Long
    uCallbackMessage As Long
    uEdge As Long
    rc As RECT
    lParam As Long
End Type

Private Declare Function SHAppBarMessage Lib "shell32.dll" (ByVal dwMessage As Long, pData As APPBARDATA) As Long


Function GetTaskBarSize()
    Dim ABD As APPBARDATA

    SHAppBarMessage ABM_GETTASKBARPOS, ABD

    MsgBox "Width:" & ABD.rc.Right - ABD.rc.Left
    MsgBox " Height:" & ABD.rc.Bottom - ABD.rc.Top
End Function

Function GetTaskBarHeight() As Double
    Dim ABD As APPBARDATA

    SHAppBarMessage ABM_GETTASKBARPOS, ABD

    GetTaskBarHeight = (ABD.rc.Bottom - ABD.rc.Top) * Screen.TwipsPerPixelY
    'MsgBox "Width:" & ABD.rc.Right - ABD.rc.Left
    'MsgBox " Height:" & ABD.rc.Bottom - ABD.rc.Top
End Function



Private Sub Command1_Click()
    Me.Height = Screen.Height - GetTaskBarHeight
    
    Me.Top = 0
    Me.Left = 0
End Sub
