getting the titleBar height

[MrPolite]

can someone just double-check my code? cuz it seems to be working almost fine except its one pixel off for some reason

Public ReadOnly Property TitleBarHeight(ByVal bStyle As FormBorderStyle) As Integer
        Get
           Select Case bStyle
                Case FormBorderStyle.Fixed3D
                    Return SystemInformation.CaptionHeight + _
                                  2 * SystemInformation.Border3DSize.Height
 
 
                Case FormBorderStyle.Sizable, FormBorderStyle.FixedSingle, FormBorderStyle.FixedDialog
                    Return SystemInformation.CaptionHeight + _
                             2 * SystemInformation.Border3DSize.Height
 
 
 
                Case FormBorderStyle.FixedToolWindow, FormBorderStyle.SizableToolWindow
                    Return SystemInformation.ToolWindowCaptionHeight + _
                             2 * SystemInformation.Border3DSize.Height
 
                Case FormBorderStyle.None
                    Return 0
            End Select
        End Get
    End Property

The first case switch returns a value 1 pixel less than the actual value, and the second case statement returns 1 pixel more than the actual value. I think I'm using the right stuff, why isn't it working correctly?

hmm this seems to be working fine, except I dont know where the +1 at end comes from
I noticed that sizable forms are 1 pixel bigger

Public ReadOnly Property TitleBarHeight(ByVal bStyle As FormBorderStyle) As Integer
        Get
            Dim border, height As Integer
 
            If bStyle = FormBorderStyle.SizableToolWindow OrElse _
              bStyle = FormBorderStyle.Sizable Then
                border = 1
            End If
 
 
            Select Case bStyle
                Case FormBorderStyle.Fixed3D
                    height = SystemInformation.CaptionHeight
                    border += 2 * SystemInformation.Border3DSize.Height
 
                Case FormBorderStyle.Sizable, _
                     FormBorderStyle.FixedSingle, _
                     FormBorderStyle.FixedDialog
 
                    height = SystemInformation.CaptionHeight
                    border += 2 * SystemInformation.BorderSize.Height
 
 
                Case FormBorderStyle.FixedToolWindow, _
                     FormBorderStyle.SizableToolWindow
 
                    height = SystemInformation.ToolWindowCaptionHeight
                    border += 2 * SystemInformation.BorderSize.Height
 
                Case FormBorderStyle.None
                    Return 0
            End Select
 
            Return height + border + 1
        End Get
    End Property

Hi.

I haven't tried this. I just thought this might do the trick, regardsless of FormBorderStyle.

TitleHeight = Me.Height - Me.ClientSize-Height

As far as I know, the Height is the actual height of the entire form/control, where ClientSize.Height is the height available to the user. Hence I think that the difference between the two must be the titlebar height. If the form has no border the height would return 0.

I hope this is of any help...

that's what I've always been using, but apprently it doesnt give you the correct height (I get a screenshot of the form and measure the titlebar in pixels using msPaint and it appears to be a different value when I use that code. But so far my code is working correctly )

edit: plus I think there was another problem with that. I think when I had a main menu then clientSize would become smaller and therefore I would get a value that was way off for the titlebar

Strange...perhaps it has something to do with visual styles...

Right, didn't think of that...

hmm, perhaps the GetTitleBarInfo API could do the trick.

heheh ok

umm API? well you can do it with .NET and apparently that code works fine, so why the heck not
