I have a lot of TextBoxes in my form and need to change Text of them using For i = 0... etc.
I started from(found somewhere)

VB

Dim arrText As New ArrayList
arrText.Add(_Text1_0)
arrText.Add(_Text1_1)
arrText.Add(_Text1_2)
arrText.Add(_Text1_3)

But it's wrong direction, because I can't access to TextBoxes.

Hello,

Both Windows Form Class and ASP.Net Page class have Controls collection. You can enumerate this to find your text boxes. More help can be found in following MSDN documents

Hello,

You can find an example for ASp.NET here (http://dotnetguts.blogspot.in/2008/11/finding-all-controls-on-page-in-aspnet.html). Similar concepts can be applied to Windows Forms.

No that is in a good direction. Probably you are bad implementing the suggestion. Please check (or post here) your actual code.

Solution 1, also, is good. Moreover documentation do provide useful examples, you have just to be a more careful reader.

There is no clear practical application of "how to make array of EXISTENT texboxes and access to their properties"

CPallini 5-Jun-13 8:30am

I the code YOU posted, the ArrayLIst is built using EXISTING text boxes. You may access tetxboxes properties just using the corrensponding array item, e.g. arrText(2).Text= "Foo". Do you need fries with it?

Already solved. And in vbasic need to use '( )' instead '[ ]'

You are right, fixed now.

Solution 3

VB

Dim Ctr() As Control = {_Text1_0, _Text1_1, _Text1_2, _Text1_3, _Text1_4, _Text1_5}

For i = 0 To Ctr.Length - 1
    Ctr(i).Text = "Text from FOR"
Next

Was hard to find it.

No, you are not creating array of text boxes, you are using available ones, and this is no good.
You really need to create and insert them. What would you need to find? How to call a constructor?
(Insertion is done via myControl.Parent = ...).

It's a shame that you self-accepted this "answer". This is just fake...
