[/quote] Sorry for that I forgot that barcode readers nowadays can 'behave like keyboards'. in my days it was serial ports ;-) The following might be useful: http://www.codeproject.com/Articles/17123/Using-Raw-Input-from-C-to-handle-multiple-keyboard As far as I understand it provides a means to determine which device has generated the input.

listen Shan .. you are making it read only .. during debug and before passing value to this text box make it readonly=false; after assign this value do it again readonly= true;

What is wrong with making it read-only?

Hi munesh sharma. Thanks for your immediate reply. Even if i change textmode=password. the user may manually type at least incorrect serial number. i want to protect the textbox from entire editing of user.

you use textbox property as TextMode=password
