displaying a text box

Ger Cannoll — Thu, 22 Apr 2010 11:35:27 GMT

I know this should be simple enough ...I am looping through a table and want to show the count as I am looping through. So I have txtBox.text= myCount; txtBox.refresh(); This shows the counter initially ok but if I click off the form and back on it for any reason, the number in the text box stops refreshing, even though the loop continues ok. Is there something I need to do to keep the textbox refreshing ?

Hi Gerard,

Yes, you can use a BackgroundWorker to update the textbox. Basically the problem is that you are using the form's thread to update the textbox from the loop and if you move out of the form, that thread will not continue to refresh the textbox, you need to use a separate thread to do that.

The BackgroundWorker is pretty easy to use and there are lot of samples in Google on how to use it.

Hi,

Don't know if this will make any difference but try refreshing the form rather than the control.

Cheers, Peter
