Null Style problem with Windows Vista

[dutch]

Dear All,

The login screen is work perfect in Windows XP (without anything in each corner) but it shows incorrect in Windows Vista as picture (not show round corner).
- LOGIN1.BMP

- LOGIN2.BMP

- Login XP

- Login Vista

Code: Select all  Expand view

    DEFINE BITMAP oBmp1 FILE 'BMP\LOGIN1.BMP' OF oDlg
    DEFINE BITMAP oBmp2 FILE 'BMP\LOGIN2.BMP' OF oDlg
   
    DEFINE BRUSH oBrush STYLE NULL  // FILENAME 'HOME.BMP'

    DEFINE DIALOG oDlg;
           BRUSH oBrush ;
           STYLE WS_POPUP ; // nOr( DS_MODALFRAME, WS_POPUP, WS_DLGFRAME, WS_SYSMENU, 4 ) ;
           FONT oFnt0 ;
           PIXEL FROM 0, 0 TO 415, 470 ;
           TITLE "EASYFO"

....             

    ACTIVATE DIALOG oDlg CENTER ;  // ON INIT SETTRANSP( oDlg ) ;
              ON PAINT ( PalBmpDraw( oDlg:hDC, 0, 0, oBmp2:hBitmap, 0, 0, 0, SRCPAINT ),;
                         PalBmpDraw( oDlg:hDC, 0, 0, oBmp1:hBitmap, 0, 0, 0, SRCAND ))


Thanks in advance,
Dutch

Dutch,

BRUSH null does not behave the same in Vista as in XP.

You have to do it in a different way

[dutch]

Dear Antonio,

Null Style is my big problem for Vista. Because it shows incorrect in many screens as following sample. How can I fix it?

Code: Select all  Expand view

   DEFINE BRUSH oBrush STYLE NULL
   
   DEFINE DIALOG oDlg RESOURCE 'RMASSIGN' ;
          BRUSH oBrush ;
          FONT MEMVAR->oFont

   REDEFINE BTNGET oGet VAR cRmsNo ID 101 ;
            UPDATE ;
            VALID  (VacantRm(oGet,cRmsNo,TBL->TBL_RMTY,TBL->TBL_ARR,TBL->TBL_DEP,,TBL->TBL_SHRNO)) ;
            ACTION (VacantRm(oGet,cRmsNo,TBL->TBL_RMTY,TBL->TBL_ARR,TBL->TBL_DEP,,TBL->TBL_SHRNO,,.T.),oDlg:End())

   bInit := {|| oDlg:Move( aDim[ 1 ]+MEMVAR->TopWin+nTop, aDim[ 2 ]+MEMVAR->LeftWin+4, aDim[3], aDim[4] ) }

   ACTIVATE DIALOG oDlg ON INIT Eval( bInit )  RESIZE16


Thanks&regards,

Dutch,

This is a modified version of fwh\samples\newhelp.prg. Please test it and see that the transparency works fine in Vista. (It is based on an Enrico's posted code with some modifications):

Please note the use of CLR_BLUE. Please use a color that it is not used in your bitmap!

Dear Antonio,

It works almost perfectly but it has a problem. The SAY with ::lTransparent is through the bitmap to background under bitmap as following. Can it transparent only SAY BACKGROUND (do not pass BITMAP)?

Code: Select all  Expand view

     @ 80,45 SAY oSay[1] PROMPT "Login Name" COLOR CLR_WHITE SIZE 50,12 PIXEL
             oSay[1]:lTransparent := .T.

     @ 93,45 GET oGet[1] VAR cLogin PICTURE '@!' COLOR CLR_BLUE, CLR_WHITE SIZE 140, 14 PIXEL ;
             VALID ((!empty(cLogin).and.if(lChk := ChkUser(@cLogin,@cLang), ( oCbx:Refresh(), .T. ), (oGet[1]:Refresh(),.F.) )).or.oBtn:lMouseOver)

     @ 108,45 SAY oSay[2] PROMPT "Password" COLOR CLR_WHITE SIZE 50,12 PIXEL
              oSay[2]:lTransparent := .T.

     @ 121,45 GET oGet[2] VAR cPass PICTURE '@!' COLOR CLR_BLUE, CLR_WHITE SIZE 140, 14 PASSWORD PIXEL ;
              FONT oFnt2 ;
              VALID (oBtn:lMouseOver.or.(!empty(cPass).and.iif(lChk := ChkPass(@cPass),(oBtn:SetFocus(),.T.),(oGet[2]:Refresh(),.F.))))     


Thanks&regards,

[Antonio Linares]

What color are you using as the transparent one ?

In this call:
SETLAYEREDWINDOWATTRIBUTES( oDlg:hWnd, CLR_BLUE,, LWA_COLORKEY )

[dutch]

Dear Antonio,

I use CLR_GREEN. If I remark :lTransparent and put BACKGROUND text as CLR_GREEN. The SAY BACKGROUND will be invisible (Transparent through background of BITAMP.

Regards,
Dutch

[Antonio Linares]

Dutch,

Could you please provide a small and self contained example to test it here ? thanks,

[Antonio Linares]

Dutch,

You don't have to keep using the BRUSH NULL.

Thats why I ask you for an example. I don't know for sure how you are doing it.

Dear Antonio,

I try to change color and many parameter but the resault is the same.

[Antonio Linares]

Dutch,

Why don't you paint those SAYs as part of the bitmap ?

[Antonio Linares]

[dutch]

Dear Antonio,

I did but need to know how to do ::lTransparent of this case if any?

Dutch
