Barcode scanner input

Question

Hi .
I have an application that needs to receive bar code scanner input (the DS6707 from motorola). This application also discusses with 3 or 4 boards that run in parallel (using serial port com). So I have at least 5 threads that are running in parallel: one for each port com, one supervisor, and the main for the user interface.
I created a control to get the data coming from the barcode scanner, but sometimes I lose some number on my barcode, or sometimes I receive ‘?’ instead of a number.
If I create a thread that read the standard input, it works, I always receive all my numbers, but the problem is that I have the standard input that is visible and I don’t want.
I tried to used keyboard methods from the windows library , but I don’t know how to proceed.
Thanks for your help.

Answer 1

I have a question about a keyboard wedge scanner input.
I have a single panel with several text boxes placed in a grid.
I post the output from 8 flash programmers in the boxes.
I have a single wide text box below these to display general program status.
My problem is when I scan the barcodes from the panel array, all data goes
through the Upper Left text box. i want the data to go through the big box on the bottom.
The reason I am using the text box in the upper left, is because that is where the data went
when I scanned the bar codes. I was desperate to get the project moving forward.
And the StdIO window caused too many problems.
Question,  How do I move the cursor to the other text box ? I have tried many Set / Get
Attribute parameters.  If there exists any "how-To" example code I would be grateful.
void ReadSerialNumber1 (char* BigBuffer9)
 statspanelHandle  = TESTER_DialogGetSubPanelCVIHandle(&StatsHandle);
 statspanelHandle  = GetCtrlVal (StatsHandle, STATSPANEL_TEXTBOX_2, BigBuffer9);
 DisplayPanel(StatsHandle);
 fprintf(Stream1,"Serial Number..~%s~\n",BigBuffer9);
code in main section
  sprintf(LittleBuffer1,"\n  -- SCAN Serial Number Nest 1-- ");
  WriteTextBox1(LittleBuffer1);
  PN_Size = strlen(LittleBuffer1);
  for(x=0;x<128;x++){ LittleBuffer1[x] = '\0';}
  PN_Size = strlen(LittleBuffer1);
  while(PN_Size != 10){
     int Stat_Val;
     Delay(0.5);  
  ReadSerialNumber1(LittleBuffer1);
     PN_Size = strlen(LittleBuffer1);
  if(TEST_CHECK_BREAK) break;
  if(PN_Size == 10)  Ready_Go = 1;
  strcpy(sSerialNum1,LittleBuffer1);
  strcpy(Scan_Buffer[0],LittleBuffer1);
  if(!strcmp(ModuleType2,"DSM")) strcpy(Scan_Buffer[1],LittleBuffer1);
  ResetTextBox2();
  if(TEST_CHECK_BREAK) break;
  sprintf(LittleBuffer1,"____%s____",Scan_Buffer[0]);  
  WriteTextBox1(LittleBuffer1); 
  Ready_Go = 0;
