Resize Bitmap with API code?

[BRENT GARDNER]

Hi,

This is the code I now have to use in place of ADD GRAPHIC CONTROL. This allows a button to be placed over label bitmap and execute with a hot key. Problem is it does not resize bitmap like GRAPHIC RENDER does. Is there API code to resize bitmaps?

      '-----------------------------------------
      CONTROL ADD LABEL, hDlg43, %IDG_BMPLABEL, "", 0, 0, 660, 700,  %SS_BITMAP
      PicTMap = LoadImage(%Null,"PICT\BaloonBorder2.bmp"  , %IMAGE_BITMAP,0,0, %LR_LOADFROMFILE)
      CONTROL SEND hDlg43, %IDG_BMPLABEL, %STM_SETIMAGE, %IMAGE_BITMAP, PicTMap
      CONTROL ADD TEXTBOX, hDlg43, %IDS_TEXT, "",      45,45,570,622, _
        %WS_CHILD OR %WS_VISIBLE OR %ES_MULTILINE OR %ES_AUTOVSCROLL _
         OR %ES_READONLY OR %ES_WANTRETURN, %WS_EX_CLIENTEDGE ' These styles allow mousewheel
      CONTROL ADD BUTTON, hDlg43, %IDS_BUT, "&Stop", 300,675,80,20
      '--------------------------------------------------------------------------------
    CALLBACK FUNCTION BirthAnnivCALLBACK()
    '------------------------------------------------------------------
    LOCAL fBmp AS LONG
      SELECT CASE CBMSG
      CASE %WM_INITDIALOG                         ' <- sent right before the dialog is displayed.
        ' set up subclass proc & record old proc add in %IDS_TEXT userdata. (TT Colin Schmidt)
        ' Hides vertical scrollbar, but still allows mousewheel to move cursor up or down
        Setwindowlong Getdlgitem(CBHNDL, %IDS_Text), %GWL_USERDATA, _
        SetWindowLong(GetDlgItem(CBHNDL, %IDS_Text), %GWL_WNDPROC, CODEPTR(TextBoxProc))
        fBmp = LoadImage(%Null, "PICT\BaloonBorder2.bmp", %IMAGE_BITMAP,0,0, %LR_LOADFROMFILE)
        CONTROL SEND CBHNDL, %IDS_BUT, %STM_SETIMAGE, %IMAGE_BITMAP, fBmp

        CONTROL SET FOCUS CBHNDL, %IDOK '%IDS_BUT ' Added 10-10-2007 or button didn't work?
          CASE %WM_COMMAND                        ' <- a control is calling
            SELECT CASE CBCTL                     ' <- look at control's id
               CASE %IDCANCEL
                  IF CBCTLMSG = %BN_CLICKED THEN  ' end prog on Esc
                   DIALOG END CBHNDL, 0           ' Means go back to SUB BirthAnniv
                  END IF
               CASE %IDS_BUT  '%IDOK '%IDS_BUT    ' end prog on Stop [Stop]
                  IF CBCTLMSG = %BN_CLICKED THEN
                   SLEEP 500
                   DIALOG END CBHNDL, 1           ' Means go back to SUB BirthAnniv
                  END IF
            END SELECT
      END SELECT
    END FUNCTION

Was using:

      CONTROL ADD GRAPHIC, hDlg43, %ID_FRAM, "",        0, 0, 660, 700, %SS_NOTIFY  '660,670
      GRAPHIC ATTACH hDlg43, %ID_FRAM
      GRAPHIC RENDER "PICT\BaloonBorder2.bmp", (0, 0)-(660,700) '700)'670

Need to resize bitmap according to dialog size with API code?

[Michael Mattias]

Start with StretchBlt Win API function:

The StretchBlt function copies a bitmap from a source rectangle into a destination rectangle, stretching or compressing the bitmap to fit the dimensions of the destination rectangle, if necessary. The system stretches or compresses the bitmap according to the stretching mode currently set in the destination device context.

See "Problems with New Developement, Maybe?". Figured out how to
use "CONTROL ADD GRAPHIC" , so no need for API stretch at this time.
