Windows Mobile Application Help

Im using Visual Studio 2008
Heres what im trying to do.
I have a form that has a start button, 2 small text box, 1 multiline textbox, and a finish button
Start button just enables all the other textboxes and button to be active.

2 small text box are named txtProduct, and txtRow, multiline textbox is called txtScan

Finish button to take whatever is in the txtScan button and save it as a text file.

Heres what im having issues with.
I want the txtscan textbox to take whats in txtproduct, txt row, and then whatever i scan in the barcode and put that in a string in the txtScan box, and basically repeat that whenever i scan a new bardcode. so it would look like this

07603(txtProduct),02(txtRow),093024,(whatever the barcode reads)
07603,02,093025,
and so on
Any help would be great. Thanks.

Hey,

I think this question is pretty much related to your other thread.

Please don't start multiple threads for essentially the same question.
