Google'n help for my game - resize form this looks just like what I need.
So I signed up in hope of help.
I got vb6 and loaded this module and added code to form_load()

I get a err.num 438
"Run-time error '438' Object doesn't support this property or method"
It don't like tab.index

I tried a few changes but nothing helped.

Any clues to why I am getting this error?

The Zip file seems to be corrupt. Does anyone have the original?

Finally a solution. Thanks a lot PsychoCoder!!!

EDIT:
I noticed something however. Suppose you resize your form (manually by click and drag), the SetFontSize() function runs. Now when the screen size reaches a particular lower limit, the font size returned will not be a valid value. So an error is generated. Basically this happens when Font Size becomes zero.

Why use the .zip file? This is a tutorial, so you should learn it, rather a simple copy paste and compile.

I have tried, but could not get the code to work. If I saw it in a project file, I could replicate it. Do you have it working?

I got it working

However I get an error when running when the program tries to resize the form menu. Any ideas how to put this into an If statement?

Thanks in Advance. LS

Why is anyone trying to even use this code with .NET?

.NET has good form resizing code, anchors etc since the outset... look at the form and object properties, it is VERY simple and can even anchor to edge of other objects... which is much better than this code.

I've done a little work on this code for myself, I will post it up later/tomorrow.

ok i tired this tutorial and run into a few probs i made a user form and put a label and a listbox and a menu

first when resizing i get Run-time error '438' Object doesn't support this property or method then highlights -

Public Sub GetLocation(frm As Form)
Dim i As Integer
'   Load the current positions of each object into a user defined type array.
'   This information will be used to rescale them in the Resize function.
 
'Loop through each control
For Each curr_obj In frm
'Resize the Array by 1, and preserve
'the original objects in the array
        ReDim Preserve List(i)
        With List(i)
                .Name = curr_obj
                .[b]Index = curr_obj.TabIndex[/b]
                .Left = curr_obj.Left
                .Top = curr_obj.Top
                .width = curr_obj.width
                .height = curr_obj.height
        End With
        i = i + 1
 
Next curr_obj
 
'   This is what the object sizes will be compared to on rescaling.
        iHeight = frm.ScaleHeight
        iWidth = frm.ScaleWidth
End Sub

as this only happens when the menubar is present/visible i assume that the tabindex cannot be assigned to this control

how do we bypass this i tried using error handle but cannot seem to grasp error handling as of yet

can we have a solution if possible where the resize works with a menubar.

secondly this is for information only the error regarding the setfontsize() i managed to work this out by adding this statment in both form_load() & form_resize()

 If lblinstructions.FontSize < 8 Then
            lblinstructions.FontSize = SetFontSize
        End If

thanks for any help with the menubar resize.

        End If

thanks for any help with the menubar resize.

ok been working with this and got a solution to the probelm with resizing with a menubar added to the userform

here is what i added to the module code

If curr_obj = FileMenuBar Then
        On Error GoTo ErrorH

ErrorH:
    If Err.Number = 438 Then
' do nothing
    Err.Clear
    End If

and it sits in the module like this

Public Sub ResizeControls(frm As Form)
Dim i As Integer
'   Get ratio of initial form size to current form size
x_size = frm.ScaleHeight / iHeight
y_size = frm.ScaleWidth / iWidth
 
'Loop though all the objects on the form
'Based on the upper bound of the # of controls
For i = 0 To UBound(List)
        'Grad each control individually
        For Each curr_obj In frm
        If curr_obj = FileMenuBar Then
            On Error GoTo ErrorH
                            'Check to make sure its the right control
                If curr_obj.TabIndex = List(i).Index Then
                        'Then resize the control
                         With curr_obj
                                .Left = List(i).Left * y_size
                                .width = List(i).width * y_size
                                .height = List(i).height * x_size
                                .Top = List(i).Top * x_size
                         End With
                End If
                End If
ErrorH:
    If Err.Number = 438 Then
    Err.Clear
    End If
        'Get the next control
        Next curr_obj
Next i
End Sub

Public Sub GetLocation(frm As Form)
Dim i As Integer
'   Load the current positions of each object into a user defined type array.
'   This information will be used to rescale them in the Resize function.
 
'Loop through each control

'Resize the Array by 1, and preserve

        With List(i)
                .Name = curr_obj
                .Index = curr_obj.TabIndex
                .Left = curr_obj.Left
                .Top = curr_obj.Top
                .width = curr_obj.width
                .height = curr_obj.height
        End With
        i = i + 1
ErrorH:
    If Err.Number = 438 Then
' do nothing
    Err.Clear
    End If
    End If
Next curr_obj
 
'   This is what the object sizes will be compared to on rescaling.
        iHeight = frm.ScaleHeight
        iWidth = frm.ScaleWidth
End Sub

@DocType this code was for Visual Basic 6, not VB.NET (Notice the VB6 in the title). That's probably why it doesn't work
