Centering A Form On The Screen
- Set the StartUpPosition property for the form to 2 - CenterScreen.
This code will cause entering msgbox and inputbox statements into any of the form's events to display the dialog box in the center of the screen.
Centering a Control Horizontally
On A Form
- In the active or load event for the form with the control enter the following code
x.Move (Me.Width - x.Width) / 2
replacing x with the name of the control.
Should you want to center it vertically too (would probably produce undesired results) add
(Me.height - x.Height) / 2
after the above code replacing x with the name of the control.
Note if the form is to be loaded maximized you will need to replace the word Me with Screen to avoid having the buttons become centered within the design time dimensions of the form.
Horizontally Centering Two Side By Side Controls On A Form
- In the general section of the form with the controls enter the following code:
Sub CenterControls(LeftControl As Control, RightControl As Control)
Dim NewLeft1 As Double
Dim Width1 As Double
`center both controls individually on the form
`if sub routine ended here 2nd control would be on top of 1st
LeftControl.Move (Me.Width - LeftControl.Width) /
RightControl.Move (Me.Width - RightControl.Width) / 2
Width1 = LeftControl.Width
NewLeft1 = LeftControl.Left
NewLeft2 = RightControl.Left
`loop until the stored left value for the
left control + its stored
`width equals the stored left value for the right control
Do Until NewLeft1 + Width1 = NewLeft2 - 1
`decrement the stored left value for the left control by
NewLeft1 = NewLeft1 - 1
`increase the stored left value for the right control by 1
NewLeft2 = NewLeft2 + 1
`change the controls left values to the new stored left values
Note: Do not change the subroutine to have
the actual left values updated in the loop in place of the variables as this will result in the controls movement being visible on screen along with flickering unless the controls are made invisible during the
- In the active or load event for the form with the control enter the following code:
call CenterControls(l, r)
replacing l with the name of the control on the left in the pair and r with
the control on the right in the pair.)
