resolution problem 100 Points

Hi all, I have a form with a graphic image in the middle. The form's properties is set to "maximized". On my monitor the gragphic is centered very nice at 640 X 480. When I view the image on a friends computer with a higher resolution the image shrinks instead of staying in the middle of the screen.

Is there code to force the image on the form to stay centered at different resolutions on other computers ? It is important to have the image on the form remain centered and the form itself to stay maximized.

Any working code would be appreciated for VB 5.0

Thanks

Put this in your form_load.

Picture1.Move (Me.ScaleWidth - Picture1.ScaleWidth) / 2, (Me.ScaleHeight - Picture1.ScaleHeight) / 2

Us the form_resize event (executes even when you don't actually resize it) to move the picture:

Private Sub Form_Resize()

    Picture1.Move (Form1.Width - Picture1.Width) / 2, (Form1.Height - Picture1.Height) / 2

End Sub

You can use this code:
Private Sub Form_Resize()
    If Me.WindowState = vbMinimized Then Exit Sub
   
    With Image1
        .Top = (Me.ScaleHeight / 2) - (.Height / 2)
        .Left = (Me.ScaleWidth / 2) - (.Width / 2)
    End With
End Sub

hi stnic,
try this code.it should use whatever resolution the monitor has.

leo


Private Sub Form_Load()
WindowState = 2
End Sub

Private Sub Form_Click()
scw = Form1.ScaleWidth
sch = Form1.ScaleHeight
pw = Picture1.Width
ph = Picture1.Height
Picture1.Left = (scw - pw) / 2
Picture1.Top = (sch - ph) / 2
End Sub

Set the StartUpPosition of the Form in design mode to vbStartUpScreen.

To clarify:
vbStartUpScreen=2 and it centers the form on the whole screen.

anthony_glenwright's is a very neat solution.

anthony's got the right of it, but with one small change:

Picture1.Move (Me.ScaleWidth - Picture1.Width) / 2, (Me.ScaleHeight - Picture1.Height) / 2

suggest you use Image control show picture, and set property Stretch = True, now the picture will fill all the Image area, just need code:
Private Sub Form_Resize()
   If Me.WindowState = vbMinimized Then Exit Sub
   
   Image1.Move 0, 0, ScaleHeight, ScaleWidth
End Sub

Hi All, what if you have more than one image in a group and they all have to stay centered with the form maximized on monitors with a higher resolution than 640 X 480 ?

Thanks

What do you mean by more than one image in a group?

Hi anthony_glenwright, what i mean is six images (like the first six letters of the alphabet). Each image is placed about an inch from the other in two rows (three per row) forming the center of the screen.

If i had six images how would I change your code to make sure all of the images were centered ? Or does the Picture1 in your code take care of all of this ?

I'm asking because I have no way of testing this until later today at my friends house. I am stuck with this video card that stays on 640 X 480.

Thanks

In that case, cheat:

Put the six image controls into a picture box with all the correct spacing (and centered in said picbox!). Turn the picbox's border off. Now use the centering code for Picture1.
