VB/VBA: Set TextBox and Label text to Vertically Align Center
Hi all, working in Access 2003, I was annoyed that I couldn't get my labels to align vertically unless I manually played with the .TopMargin property of each control. I whipped up this function that aligns the text vertically so I wouldn't need to do it manually anymore. Hopefully it can be of use to some of you
Code:
'Sets the vertical alignment of a label or textbox to "Center"
'NOTE:
'MinimumMargin: the value of the smallest margin Access allows in twips. If you set the .TopMargin
'to "0", Access will actually place a gap equal to 1 point (or 20 twips) rather than actually
'placing the text at the very top border of the control. FURTHER NOTE: Access sucks.
'
'BorderWidth: half the value of .BorderWidth in twips. As you increase the border (Hairline, 1pt, 2pt, etc..)
'Access expands the border equally from the center. We're only concerned with the "inner" section of the border.
'
'TwipsPerPoint: global constant set to 20
Public Sub VerticalAlignCenter(ByRef ctl As Control)
On Error GoTo ErrorCode
Dim MinimumMargin As Integer
Dim BorderWidth As Integer
If Not ((TypeOf ctl Is TextBox) Or (TypeOf ctl Is Label)) Then Exit Sub
MinimumMargin = 1 * TwipsPerPoint
BorderWidth = (ctl.BorderWidth * TwipsPerPoint) / 2
ctl.TopMargin = ((ctl.Height - (ctl.FontSize * TwipsPerPoint)) / 2) - MinimumMargin - BorderWidth
ErrorCode:
Exit Sub
End Sub
Chop it up, modify it, use it however you want. If you improve it in any way, please post your changes so that I can learn..
Update: My code doesn't work for controls with multiple lines of text.. It sets the TopMargin as if the top line of text is the only line present in the control. Does anyone have any creative workarounds for this glitch?

Thread Moved
Thanks for the submission
You might want to note that it will require a MSForms Textbox or Label control if being used outside of VBA.

Re: VB/VBA: Set TextBox and Label text to Vertically Align Center
That was such a useful piece of code, the easiest to find on google. I tweaked it to allow multiple lines of code... cheesy, probably, but it worked for me. Thanks for the super code, and I hope someone finds my tweak useful/functional.
vb Code:
Public Sub VerticalAlignCenter(ByRef ctl As Control)
On Error GoTo ErrorCode
Dim MinimumMargin As Integer
Dim BorderWidth As Integer
Dim TwipsPerPoint
TwipsPerPoint = 20
If Not ((TypeOf ctl Is TextBox) Or (TypeOf ctl Is Label)) Then Exit Sub
'Figure out how many lines it is
Dim LenOfText, WidOfBox, NumberOfLines, HtOfText
If TypeOf ctl Is TextBox Then
LenOfText = ctl.Text
Else:
LenOfText = ctl.Caption
End If
'how wide is this puppy?
WidOfBox = ctl.Width
LenOfText = (Len(LenOfText) * TwipsPerPoint * ctl.FontSize) / 2
NumberOfLines = Int(LenOfText / WidOfBox) + 1
HtOfText = NumberOfLines * TwipsPerPoint * ctl.FontSize
MinimumMargin = 1 * TwipsPerPoint
BorderWidth = (ctl.BorderWidth * TwipsPerPoint) / 2
ctl.TopMargin = ((ctl.Height - HtOfText) / 2) - MinimumMargin - BorderWidth
ErrorCode:
Exit Sub
End Sub

Thanks for the fine-working code, Glendale. It works for me perfect. Not on the first try however..

Re: VB/VBA: Set TextBox and Label text to Vertically Align Center
I need a little more help (I tried for over two hours to make this work, still new to all this). What I don't know is how / were are you calling the VerticalAlignCenter function?

Re: VB/VBA: Set TextBox and Label text to Vertically Align Center
OK I figured it out, sort of.
I'm trying to use it on a report. The labels work perfect. The textbox in the details do not.
Tracing it through it errors at "LenOfText = ctl.Text". Ruturns a length of zero.
How do I make it work with the details section of a report?
