Dear Tore,
I changed my reader and now all thing is ok.
I have another question.
I have a textbox on my form, in this textbox user can enter goods code and take some information about it. when i use from Barcode Reader, because it send a CHR(13) code, i lost the focus from my textbox. if i delete chr(13) as you say, how i can enter the goods code in usual mode( without reader ) ?
thanks for your help
