vb.net; controlsIn vb6 a group of controls ie command buttons could be refered to by
an index number ie cmdWord(4). This was accomplished by using the index property of the control. Vb.net does not seem to have the index property for buttons. Is there a way in vb.net to refer to a group of controls in a way that includes a unique index number for the specific control to be used? Thanks, Howard Haisten jax1***@yahoo.com wrote:

If you need to know this, you have to do it by hand, ie: Dim x(1) as button x(0)=button1 x(2)=button2 then you can use x in the same way as the controlarray in vb6 Chris wrote: Show quoteHide quote > jax1***@yahoo.com wrote: >> In vb6 a group of controls ie command buttons could be refered to by >> an index number ie cmdWord(4).

Dim x() as button = {button1, button2} Just a little addition the solution is correct in my opinion, Cor Show quoteHide quote "Theo Verweij" <tverw***@xs4all.nl> schreef in bericht news:uWn7NPe%23GHA.4376@TK2MSFTNGP03.phx.gbl... > This way, you do not know which button has what index in the array. > If you need to know this, you have to do it by hand, ie: > > Dim x(1) as button > > x(0)=button1 > x(2)=button2 > > then you can use x in the same way as the controlarray in vb6 > > Chris wrote: >> jax1***@yahoo.com wrote: >>> In vb6 a group of controls ie command buttons could be refered to by >>> an index number ie cmdWord(4).

the upgrade wizard, it will add code that simulates control arrays using some VB6-backward-compatibility classes. Look at that code to see how Microsoft does it. You can also just include the index number in the control name, and then access controls as Me.Controls("lblInformation" & indexNumber). ----- Tim Patrick Start-to-Finish Visual Basic 2005 Show quoteHide quote > In vb6 a group of controls ie command buttons could be refered to by > an index number ie cmdWord(4).

Personally, I have stopped using control array-type code in
my VB.NET applications, choosing to give unique names to each control. I can bulk up your code a bit, although it is easy to use a common event handler for all of the related controls. For those situations where it might make sense to have a lot of controls with related logic, I try to find other means. For instance, I implemented a simple numeric keypad. My processing needs were met by using a common Click event, and using the Text (or Tag) property of the control to complete my processing. In other cases, I have migrated the independent controls to an owner-draw list box or grid control, which turned out better anyway. ----- Tim Patrick Start-to-Finish Visual Basic 2005 Show quoteHide quote > Using Me.Controls("lblInformation" & IndexNumer) can cause a problem > when using obfuscating techniques. > > Tim Patrick wrote: > >> If you convert a VB6 project that contains control arrays to VB.NET >> using the upgrade wizard, it will add code that simulates control >> arrays using some VB6-backward-compatibility classes.
