Brainstorming: Displaying and printing barcodes - what is the best way?

Recommended Posts

corgano

I have seen many different threads about generating barcodes, displaying them, and printing them. However at this point I am completely torn with which method to use. I am making a software that lets the user scan items, enter in information and save it in a SQLite database. For my purposes, I want to be able to display the barcode with number underneath in a similar way to most other controls eg GuiCtrlCreateBarcode( barcodenumber, x, y, width, height ). I also want to be able to print the barcode and have it be readable by the same scanner - The most successful encoding I've found is code128. Here is what I have found so far:

  • This thread has nice code that saves the output as images
    • Printing is easy and scans properly
    • Displaying the image on a pic control makes it easy to set it's x/y/width/height
      But..
    • The code does not let you directly specify the width / height, so displayed image on GUI is ALWAYS skewed.
    • Getting output images the right size with that code is very difficult
    • I cannot find any examples of drawing barcodes to an image that let you specify width / height
    • This example 
  • Several threads use Static controls
    • Look very nice on GUI, easy to get explicit position and size
      But...
    • I know of no way to turn a bunch of static controls into something printable
    • I didn't find any examples that had numbers at the bottom of the barcode
  • The third solution I found was using a barcode font
    • Can look nice, depending on font
    • Shouldn't be hard to print
      But..
    • Depends on additional font being installed
    • Some fonts don't scan correctly
    • How do you specify a width / height of an area you want the barcode to fill when using a font?

I'm really at a loss as to how to move forward. Maybe there's an example I missed that is better suited to what I could find? PErhaps someone has experience writing barcode scanning / generating / printing software and can share the experiences. Can someone bounce a few ideas back and forth with me on the best way to proceed?

      Hi guys,
      I'm learning about GUI's, I'm trying the below code, the idea being if I press the letter "e" while I have the GUI open I want the label color to change to green (I'm using a UDF for label colors). But every time I press "e" on my keyboard I just get a "ding" sound from my speakers and nothing changes with the label.
      I've looked at using something like "While GUIGetMsg() <> $GUI_EVENT_CLOSE" as I've seen it in other code instead of "While 1", but I don't think it's relevant.
      #include <GUIConstantsEx.au3>; for GUI... #include <GUIRichLabel.au3>; UDF for rich text label fonts #include <Misc.au3>; for _IsPressed $myLetter = "e" $hGUI = GUICreate("test", 700, 60) $lbl2 = _GUICtrlRichLabel_Create($hGUI, '<font color="purple">' & $myLetter & '</font>', 10, 10); , 260, 25 GUISetState(@SW_SHOW) Local $hDLL = DllOpen("user32.dll") While 1 if _IsPressed(Hex($myLetter), $hDLL) Then While _IsPressed(Hex($myLetter), $hDLL) Sleep(250) WEnd _GUICtrlRichLabel_SetData($lbl2, '<font color="green">' & $myLetter & '</font>') Sleep(2000) DllClose($hDLL) Exit EndIf Sleep(50) WEnd DllClose($hDLL) I am using an array of letters that I'm wanting to do this for, but as I can't get it to work I've stripped it down to the simplest code I can think of to try and get this working first. Appreciate any help.
      Thanks!

      hi dears, i have an question please if you can help me.
      i maked an program to do some functions
      and this program works with the global hot keys
      i added an option to the users to change the hot keys
      when i searched about how to do that i found this UDF
      GUIHotkey.au3
      http://www.autoitscript.com/forum/index.php?showtopic=107965
      but the problem here that this UDF cant be detect the win key.
      can you help me to add it, or if there are any others UDFSS wich do that work please give me some.
      i hope that my question is clear for you.
      thanks in advance

      Hello everyone,
      I have a radio button ($Radio1), which I want to disable as soon as another one get's checked (Radio5). (The system fails if the radio button i'm troubling with also gets checked).
      I know how to disable him:
      If GUICtrlRead($Radio1)=1 And Not BitAND(GUICtrlGetState($Radio5), $GUI_DISABLE) Then GUICtrlSetState($Radio5, 128) But if i try to enable $Radio5 again, after $Radio1 isn't checked anymore, it fails:
      If GUICtrlRead($Radio1)=Not 1 And Not BitAND(GUICtrlGetState($Radio5), $GUI_ENABLE) Then GUICtrlSetState($Radio5, 64)  
      Anyone knows why?

      Good evening everyone
      First, I want to apologize with you for the title not very clear, but I thought a little bit on which title to set at the thread, and this is the one that came in mind.
      Now, let me explain what I'm trying to understand.

      I am making an application ( with n clients ), with an SQLite Database, which has a Main form, and n sub-forms... 
      Since these sub-forms are called several times, because they are used to add or update records to the Database, I put the code that generates the GUI of these sub-forms in Functions.
      There are two sub-forms which are "treated" as two main forms, since even them have n sub-forms, which perform various tasks.
      Where am I stucked?

      For the Main form I created a Status Bar, in order to display messages ( add/delete/update/search results ), and it works perfectly with all the forms which don't have other sub-forms.
      For the two forms, which indeed have n sub-forms, I created two separated Status Bars, which are (re)created everytime I call the function that then displays the form.
      Practically, I can't set icons to these two Status Bars, and I don't know why.
      I'm really sorry that I don't feel clear enough, so, here you are an example of what I am saying.
      I recreated exactly what my script does:
      #include <GuiButton.au3> #include <GUIConstantsEx.au3> #include <GuiStatusBar.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) Global $frmSubForm, _ $txtSubFormField, _ $sbSubFormStatusBar, _ $objSB_IconError = _WinAPI_LoadShell32Icon(109), _ $objSB_IconInformation = _WinAPI_LoadShell32Icon(277) #Region ### START Koda GUI section ### Form= $frmMainForm = GUICreate("Main Form", 300, 300, -1, -1) GUISetOnEvent($GUI_EVENT_CLOSE, "ExitApplication") $sbMainStatusBar = _GUICtrlStatusBar_Create($frmMainForm) $btnCreateSubForm = GUICtrlCreateButton("Create Sub Form", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "GenerateSubForm") GUICtrlSetFont(-1, 10, 400, 0, "Arial") _GUICtrlStatusBar_SetSimple($sbMainStatusBar) _GUICtrlStatusBar_SetText($sbMainStatusBar, "") GUISetState(@SW_SHOW, $frmMainForm) #EndRegion ### END Koda GUI section ### While 1 Sleep(100) WEnd Func ExitApplication() Exit EndFunc Func GenerateSubForm() #Region ### START Koda GUI section ### Form= $frmSubForm = GUICreate("Sub-Form", 300, 300, -1, -1, -1, -1, $frmMainForm) GUISetOnEvent($GUI_EVENT_CLOSE, "DeleteSubForm") $txtSubFormField = GUICtrlCreateInput("", 0, 0, 100, 20) $btnCheckSubFormField = GUICtrlCreateButton("Check Field", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "CheckSubFormField") GUICtrlSetFont(-1, 10, 400, 0, "Arial") $sbSubFormStatusBar = _GUICtrlStatusBar_Create($frmSubForm) _GUICtrlStatusBar_SetSimple($sbSubFormStatusBar) _GUICtrlStatusBar_SetText($sbSubFormStatusBar, "") GUISetState(@SW_SHOW, $frmSubForm) GUISetState(@SW_DISABLE, $frmMainForm) #EndRegion ### END Koda GUI section ### EndFunc Func DeleteSubForm() ; Declared Globally => $frmSubForm GUIDelete($frmSubForm) GUISetState(@SW_ENABLE, $frmMainForm) EndFunc Func WriteToStatusBar($sbStatusBar, $objSB_Icon, $strText) _GUICtrlStatusBar_SetIcon($sbStatusBar, 0, $objSB_Icon) _GUICtrlStatusBar_SetText($sbStatusBar, $strText) ConsoleWrite("Icon Handle: " & $objSB_Icon & @CRLF) EndFunc Func CheckSubFormField() ; Declared Globally => $txtSubFormField If GUICtrlRead($txtSubFormField) = "" Then ; Declared Globally => $sbStatusBar WriteToStatusBar($sbSubFormStatusBar, $objSB_IconError, "Field NOK.") Else WriteToStatusBar($sbSubFormStatusBar, $objSB_IconInformation, "Field OK.") EndIf EndFunc The text is set, but icon is not.
      Could someone please tell me why?
      Thanks everyone in advance  

      Best Regards.
