checkbox array - repost
Fra : brinckmartin


Dato : 11-11-02 11:23

Hi everybody!

I would like to create a control array of eight checkboxes, and then
retrieve
all eight bits/checks in a single loop structure.
I'm a skilled VB6 programmer, but in VB .NET the Index property is no longer
accesible, so I'm having a really hard time doing this...

I would like to write like the following, but the syntax doesn't allow the
property "Checked", (what do I do now?):


Dim ctrl As Control
Dim m As String
Dim b(7) As Boolean
Dim n As Integer

For Each ctrl In Controls
b(n) = ctrl.Checked
n=n+1
Next


If anybody has got a clue, I'd like to hear.

Sincerely
Martin Axelsen

Cast your Control to the appropriate type thus:

Dim ctl As Control
Dim chk As CheckBox
Dim b(7) As Boolean
Dim n As Integer

For Each ctl in Controls
If TypeOf ctl Is CheckBox Then ' Avoid InvalidCastExceptions
chk = ctl ' Gets you the Typecast
b(n) = ctl.Checked
n += 1
End If
Next ctl

Wow, I think this might be the solution,
I'll write back tomorrow (after additional coding)

Thank you for writing

Martin

Oops. Typo:

> b(n) = ctl.Checked

Should be:

b(n) = chk.checked
