Transparent background

[Scott Turchin]

Function SplashProc() As Long
  Dialog New 0, "",,, 325,146, %WS_POPUP Or %WS_DLGFRAME  To sDlg
  Control Add Image, sDlg, -1,"#1031",0,0,325,146
  Control Add Frame, sDlg, -2,"Licensed to",20, 55, 150, 35, %WS_EX_LEFT
  Control Add Label, sDlg, -3, wRegUser,    25, 65, 140, 10, %WS_EX_LEFT
  Control Add Label, sDlg, -4, wRegCompany, 25, 75, 140, 10, %WS_EX_LEFT
  Dialog Show Modal sDlg Call SplashScreen

End Function

I would like to make the label's background clear, transparent, etc, it's being put over top of a bitmap (image) and it looks kinda silly this way...

Is there a window style for this or do I have to do the paint by numbers routine??

Thanks,

Scott

In your dialog callback, draw the text during a %WM_PAINT event (Dont forget to set the background mode to %TRANSPARENT).

I'm having problems getting this to work. I've got a Label on a window. I change the color of a portion of the window to white by changing the pen and brush and then using PaintRgn to color in the area. That works fine. But my label is still using the default gray background. Any ideas? I've tried using %TRANSPARENT style for both the window and the control as well as using %WS_EX_TRANSPARENT Nothing seem to do the trick.

Here's what my WM_PAINT event looks like for the dialog.

     CASE %WM_PAINT
            hDC = BeginPaint(g_hWizzard, ps)
            SelectObject hdc, hPen
            SelectObject hdc, hBrush
            PaintRgn hDC, hRegion

            setbkmode hDC, %TRANSPARENT
            ' output our text
            CONTROL SET TEXT g_hWizzard, %ctlLabel1, "Test"
            ' the above line changes the text, but the backround isnt transparent.

            ' the following line works though with transparency.
            textout hDC, 220, 20, "Testing", 7    

            ' select the original values into the DC
            SelectObject hDC, hPenSave
            SelectObject hDC, hBrushSave

            EndPaint g_hWizzard, ps

This my old training code + I added especially TextOut in %WM_PAINT

   #Compile Exe
   #Dim All
   #Register None
   #Include "Win32Api.Inc"

   %ID_Label1 =  101
   %ID_Text1 = 201
   %ID_Button = 301

   CallBack Function DlgProc
      Dim hBrushDlg As Static Long, hBrush1 As Static Long
      Select Case CbMsg
         Case %WM_INITDIALOG
            hBrushDlg = CreateSolidBrush(%Yellow)
            hBrush1 =  CreateSolidBrush(%White)
         Case %WM_DESTROY
         DeleteObject hBrushDlg: DeleteObject hBrush1
      Case %WM_CTLCOLORDLG
         Function = hBrushDlg
      Case %WM_PAINT
         Dim ps As Paintstruct, rc As Rect, x As Long, y As Long
         BeginPaint CbHndl, ps
         Setbkmode ps.hDC, %TRANSPARENT
         Dialog Units CbHndl, 10, 20 To Pixels x, y
