how to use variable to refer to a control?I have several textbox controls in a form,.
I name them txt1, txt2, ... txt10. How dow I refer to them in a loop to get the value in text proerty of each control? For x = 1 to 10 value = txt(x).text next x Thanks Bill Since I try to give my controls business-meaning names, I don't iterate
based on an integer index. I have had some success organizing similar-ruled controls within containers such as panels or tabcontrol tabpages and using the container controls collection. Dim textitem as textbox For each textitem in form1.controls 'do stuff next textitem For each textitem in panel1.controls 'do stuff next textitem For each textitem in tabcontrol1.tabpages(1).controls 'do stuff next textitem If I have to apply a differential rule based on the exact name, an if or select case on textitem.name will work.

This is great. However, I still need to be able to refer to an actual control name. Is there a way to do that?

Not so good.> How dow I refer to them in a loop to get the value in text proerty of each (I love this answer; it /so/ annoys the .Net purists)> control? You use a Control Array. :-) No, seriously. You create an array of Controls, in this case TextBoxes, and loop through that. Dim textboxes As TextBox() = { txt1, txt2, ... txt10 } For Each tb As TextBox in textboxes value = tb.Text Next Regards, Phill W. I'm a .Net purist, and I think your answer is brilliant.
It's simple and concise, and gets the job done. Does that mean I'm really *not* a .Net purist? :-( Robin S.

I suspect the previously vehement VB bashers are all off trying to work out what their programs are doing now that they've dived into these Generics things ... ;-) Regards, Phill W. Well, there's no doubt that Generics are very cool.
But that doesn't mean there's no place in the world for an array or arraylist. After all, even though there are plasma tv's out there, some people still rely on their Sony Wegas to do the job.
