Referencing Controls - TextBox1, TextBox2, And TextBox3 - Reference Without Adding Extra Arrays

Oct 10, 2009

Lets say that I had three TextBox's and they are named TextBox1, TextBox2, and TextBox3, is there a way to do like TextBox And Rand(1,3).Text = Nothing? Something similar to this where you click a button and it will choose at randomly a textbox to clear?I know I could do like Dim Number = Rand(1,3)if Number = 1 Then TextBox1.Text = Nothingend ifif Number = 2 Then TextBox1.Text = Nothingend ifor use else if and such, but I have 12 different textbox's, not three, so, I want to shorten the code, if you could do something like TextBox And Rand(1,12).Text = Nothing that would defenitely be way shorter, can you do anything like that to put together "TextBox" and the number to reference the control? I am not looking to use the full controls list to search for the right control nor to make an array that contains the controls, I just want to reference them without adding extra arrays or searhing for them.

I'm stuck with how to copy all lines from textbox1 to textbox2, in 1 Hz. This sounds maybe odd, but my thinking was to do it in a timer set to trigger every 1000ms. textbox1 Line1 should be appended to textbox2 line1.....until theres no more lines. Of course a loop will do this, but right now I'm stuck. This will of course add all lines every time the timer ticks:

To read any form's text (except RichTextBox) line by line I've always used this splitting

Dim Lines() as String = Split(TextBox1.Text, vbNewLine)MsgBox(Lines(0))This code just works perfectly.But whenever I try this code on a RichTextBox like this:Dim Lines() as String = Split(RichTextBox1.Text, vbNewLine)MsgBox(Lines(0))The message box appears with the whole lines.I think maybe the RichTextBox1.Text() returns another new line character (means not vbNewLine).
