how would a real programmer handle a group of text boxes 1

[seminewbee2005]

I have a group of textboxes that I dealt with using a control array. txtMach(0),txtMach(1) ans so on. I am new to vb.net and have read in my research vb.net does not support control arrays. SO how to do it?
thanks!!!

for example how to do something as simple as clearing a group of 5 text boxes in code?

I meant to say i dealt with them as a control array in vb6, how to deal with them in vb.net

My choices in how to do this would be, in order of decreasing performance:

1. Have 5 separate lines of code to clear them. Put this in it's own method for clarity's sake. Simplicity is a virtue.

2. Declare an array of 5 Textboxes, and assign the five to the array when the form loads. When you need to clear them, do a For Each..Next against the array

3. Do a For Each..Next against the Controls collection, and when the control equals one of your textboxes, clear it.

waz wonderinf what that for each would look loike against the collection

say to clear all labels on a form?

for each ? I know how to do it in vb6 but not .net

 

[chiph]

from the VB.NET language spec:

ForEachStatement ::=
For Each LoopControlVariable In Expression StatementTerminator
[ Block ]
Next [Expression ] StatementTerminator

What this means is that you can do a For Each against any object that implements the System.Collections.IEnumerable interface, which most if not all collections and arrays do.

Dim c As ArrayList = New ArrayList()
Dim w as widget

' Add some widgets to c here

For Each w in c
   Console.WriteLine(w.ToString())
Next

thanks so much!!!!!!!!!!!!!!.
what does the console mean?

Console spits the output to the console window if you are running a console app. You'll probrably want to use Debug.WriteLine instead.
