Progress bar function in Common Control Extender

[stevengraff]

Jim,

I tried a few permutations, then gave up, as nothing was appearing on the screen.

Does it work? what's the trick? Have you got an example you can show?

Thanks,
SG

Here is a simple sample that should help:

Code: Winbatch

#DefineFunction MyDialogCallbackProc(MyDialog_Handle,MyDialog_Message,MyDialog_Name,MyDialog_EventInfo,MyDialog_ChangeInfo)
   ;Return code constants
   RET_DO_CANCEL=0           ; Cancels dialog
   RET_DO_DEFAULT= -1        ; Continue with default processing for control
   RET_DO_NOT_EXIT= -2       ; Do not exit the dialog
        ;DialogprocOptions Constants
   MSG_INIT=0                    ; The one-time initialization
   MSG_TIMER=1                   ; Timer event
   MSG_BUTTONPUSHED=2            ; Pushbutton or Picturebutton
 
   ON_EQUAL = @TRUE                                         ; Initialize variable ON_EQUAL
   switch MyDialog_Message                                  ; Switch based on Dialog Message type
      case MSG_INIT                                         ; Standard Initialization message
         DialogProcOptions(MyDialog_Handle,MSG_BUTTONPUSHED,@TRUE)
         return(RET_DO_DEFAULT)

     case MSG_BUTTONPUSHED
        if MyDialog_Name == "PushButton_OK"                ; OK

              ; Dialog Disable
              ; Grey the dialog's title bar and redraw dialog as necessary. Optionally, display the system's "wait cursor".
              ; Note: If you have code that may take a long time to execute in a callback, you may need to temporarily disable
              ; the dialog. Don't forget to enable after the process is complete.
              DialogProcOptions( MyDialog_Handle, 1000, 2 )

              pgControlHandle = pgCreateProgressBar(MyDialog_Handle,500,225,250,30,0)
              itext           = pgSetColor(pgControlHandle,"225|250|30",0)
              itext           = pgSetColor(pgControlHandle,"25|250|30",1)

                TimeDelay(.1)
              Next
             
              ccShow(pgControlHandle,0)

              DialogProcOptions( MyDialog_Handle, 1000, 0 );re-enable
              return(RET_DO_NOT_EXIT)

        elseif MyDialog_Name == "PushButton_Cancel"        ; Cancel
              return(RET_DO_DEFAULT)

        endif                                              ; MyDialog_Name
        return(RET_DO_DEFAULT)

   endswitch                                                ; MyDialog_Message
