vb.net - Windows CE Generate Log on Barcode Scan -


at moment, faced small project update current bar-code system store log file on scan. however, i'm not provided source code current system. thinking maybe can develop small .exe run , it's job store id scanned current timestamp text file named log.txt.

here's i'm provided with:

  1. a small touchscreen device running on windows ce built-in bar-code scanner (imager) , few other ports including usb port.
  2. a memory stick containing object codes (exe, dll, pdb, bat , xml) , other multimedia files.
  3. sdk cd containing sdk platform installer (.msi) requiring vs2005 sp1 installed.

now i'm confused on how job done. i've been spending past 3 days researching this. 1 of google findings suggest bar-code scanner works keyboard input? hence, made simple vb6 application textbox store contents of , reset textbox @ same time when 10-digit id inputted. application not executable in device though (i found out vb6 exe not executable in wince, sadly).

furthermore, tried open ms wordpad in device , attempted scan bar-code. nothing copied wordpad though. thought bar-code scanner works identically keyboard input? mistake? clarification highly appreciated.

i'm new bar-code , wince development , if helps, i'm familiar following languages (in-order): c#, vb6, vb.net, c, java. suggestion on quickest way job done? believe it's not hectic job, i'm stuck on begin.

just tell me in case further clarification needed. in advance!

edit#1:

here's tried far (assuming barcode scan works keyboard input): (using vb.net windows ce 5.0 device under vs2005)

private sub barcodetb_textchanged(byval sender system.object, byval e system.eventargs) handles barcodetb.textchanged     if (len(barcodetb.text) = 10)     'if 10 digits id have been scanned..         using writer io.streamwriter = new io.streamwriter("log.txt", true)             writer.writeline(barcodetb.text & " " & datetime.now)         end using         barcodetb.text = ""    'reset textbox     end if end sub

it works fine when input code manually. nil when tried scan bar-code.

edit#2: there several pdfs provided in website: http://www.scantech-id.com/en/support/download.php?pin=42676d021abeff1e479180ffeb4240e5

i'm sure scanner installed in com3 port if helps! still trying figure out.

edit#3: last attempt: read directly via datareceived com3 port.

i set timer sends data transmitted every 1 second if there's any. works nicely textbox updated when scan bar-code. however, output not in desirable format. doing wrong? see below: screenshot

and here's code:

private sub serialport1_datareceived(byval sender system.object, _     byval e system.io.ports.serialdatareceivedeventargs) _     handles serialport1.datareceived     q.enqueue(serialport1.readexisting()) end sub  private sub timer1_tick(byval sender system.object, byval e system.eventargs) handles timer1.tick     synclock q         while q.count > 0             receivedtb.text &= chr(13) & chr(10) & q.dequeue         end while     end synclock end sub
