    DDT Modeless as progress bar

    I saw one question in "Programming" forum about colors for progress bar.
    Because I prefer "own-drawn" progress bar, I decided to post simple sample.
    Code:
       #Compile Exe
   #Register None
   #Dim All
   #Include "WIN32API.INC"

   CallBack Function PicProc
      Static hBrush() As Long, hDC() As Long, hBmp() As Long, Clr() As Long
      Static i As Long, Done As Long, LpPaint As PaintStruct, tRect As Rect
      Static zText As Asciiz * 255
      Select Case CbMsg
         Case %WM_INITDIALOG
            ReDim hDC(0 To 2): ReDim hBrush(1 To 2): ReDim hBmp(1 To 2): ReDim Clr(1 To 2)
            hBrush(1) = CreateSolidBrush(Rgb(  0,   0, 255)): Clr(1) = %White
            hBrush(2) = CreateSolidBrush(Rgb(255, 255, 255)): Clr(2) = %Black
         Case %WM_DESTROY
            For i = 1 To 2: DeleteObject hBrush(i): Next
            InvalidateRect GetParent(CbHndl), ByVal 0, %True
            UpdateWindow GetParent(CbHndl)
         Case %WM_ERASEBKGND: Function = 1: Exit Function
         Case %WM_USER + 1
            Done = CbWparam
            InValidateRect CbHndl, ByVal 0, %True: UpdateWindow CbHndl
         Case %WM_PAINT
            GetClientRect CbHndl, tRect
            hDC(0) = BeginPaint(CbHndl, LpPaint)
            For i = 1 To 2
               hDC(i)  = CreateCompatibleDC(hDC(0))
               hBmp(i) = CreateCompatibleBitMap (hDC(0), tRect.nRight, tRect.nBottom)
               SelectObject hDc(i), hBmp(i)
               FillRect hDC(i), tRect, hBrush(i)
               SetBkMode hDC(i), %TRANSPARENT
               SetTextColor hDC(i), Clr(i)
               Select Case Done
                  Case  6 To 12: zText = "A lot of time to sleep"
                  Case 86 To 92: zText = "Wake up, almost done"
                  Case Else: zText = Str$(Done)+"%"
               End Select
               DrawText hDC(i), zText, -1, tRect, _
                  %DT_SINGLELINE Or %DT_CENTER Or %DT_VCENTER
            Next
            BitBlt hDC(2), 0, 0, tRect.nRight * Done * 0.01, tRect.nBottom, hDC(1), 0, 0, %SRCCOPY
            BitBlt hDC(0), 0, 0, tRect.nRight, tRect.nBottom, hDC(2), 0, 0, %SRCCOPY
            EndPaint CbHndl, LpPaint
            For i = 1 To 2: DeleteDC hDC(i): DeleteObject hBmp(i): Next
            Function = 0: Exit Function
      End Select
   End Function

   CallBack Function DlgProc
      Static Done As Long, hDlg As Long
      Select Case CbMsg
         Case %WM_COMMAND
            If CbCtl = 101 Then
               Done = 0
               SetTimer CbHndl, 1, 500, ByVal %Null
               Dialog New CbHndl, "", 10, 10, 176, 12, %WS_CHILD Or %WS_VISIBLE Or %WS_BORDER To hDlg
               Dialog Show Modeless hDlg Call PicProc
               Dialog Send hDlg, %WM_USER + 1, Done, 0
            End If
         Case %WM_TIMER
            Done = Done + 2
            If Done > 100 Then Dialog End hDlg: KillTimer CbHndl, 1 Else _
            Dialog Send hDlg, %WM_USER + 1, Done, 0
      End Select
   End Function

   Function PbMain
      Local hDlg As Long, hDlg1 As Long
      Dialog New 0, "Progress Bar",,, 200, 80, %WS_SYSMENU To hDlg
      Control Add Button, Hdlg, 101, "Show", 50, 40,100, 14, %BS_DEFAULT
      Dialog Show Modal hDlg Call DlgProc
   End Function
    Regions were excluded, because of problems under Win95.

    Here's another one, not the white/blue, just the standard MS broken one (er, broken image, not Progress bar)...Jim H. Helped me out on this and I actually use it in my encryption routine for doing files..
    What it does is open a new thread and process it in a new thread in case it takes a heavy toll on the system as the encryption can do...

    Timing is everything, this is not perfect, butit does work and gives the sample on how to do the standard ms progress bar...not as pretty as the one above though
