Ramesh,

oWnd:SaveToBmp( "mibmp.bmp" )

Hello Mr. Wmormar

This is not that much simple. At least in FWH 2.8 xHarbour (0.99.71 Simplex) !.

Which version of FWH and xHarbour you are using and you got it working?

I have used several methods to achive this well with in FWH. But I did
not suceeed. I had to adopt a long work around to achive this.

Thanks for your response.

Ramesh,

Code: Select all  Expand view

METHOD SaveToBmp( cBmpFile ) CLASS TWindow

   local hBmp := WndBitmap( ::hWnd )
   local hDib := DibFromBitmap( hBmp )

   DibWrite( cBmpFile, hDib )
   GloBalFree( hDib )
   DeleteObject( hBmp )

return ( File( cBmpFile ) )

Antonio,

Is that saving a bitmap snapshot of the window to a BMP file?

I think Ramesh wants to save a bitmap that is in the clipboard to a file. Is that right Ramesh?

Mr.Antonio

Thanks for your attention.

The following code is a "savedbmp.bmp" with only 14 bytes !.

Code: Select all  Expand view

#include "Fivewin.ch"

FUNCTION Main()

   LOCAL oWnd

   DEFINE WINDOW oWnd TITLE "SaveToBmp"

   @ 9, 2 BUTTON "Save To Bmp" ;
          SIZE 210, 30 ;
          ACTION  ( oWnd:SaveToBmp("SavedBmp.Bmp"), MsgInfo("Saved") )
     
   ACTIVATE WINDOW oWnd
   
RETURN nil     


As Mr.James said, I need to save the contents of clipboard to a BMP file.

I am using FWH 2.8 (Sep. build) + xHarbour 0.99.71 (Simplex)

This was working very well in our earlier versioins. But it is not working.

And I have come across several postings on our forum with the same
complaint that they are getting a saved BMP file only with 14 bytes.

Currently I have adopted a very long work around using some 3 party utilitys to achive this result.

Plase do help.

Mr.Antonio

As I have already pointed, the same functionality was working OK prior to
FWH 2.8 and it stopped working in 2.8 I don't know why.

Can you please check with FWH 2.8 (Sep. build) + xHarbour 0.99.71 (Simplex) and suggest me any way out ?

For your information, we have spoken several times in the forum earlier on
the same issue. And you said the same thing. I hope atleast this time so
will suggest me a way out. Because the working around way I am following presently is not giving the expected result some times and I am
facing problems.

My previous posting on the same subject for your reference:

Ramesh,

> Can you please check with FWH 2.8 (Sep. build)

We can't provide tech support for 2.8 september year 2006. There have been lots of changes both in Harbour/xHarbour and FWH. Please understand it.

We can only suggest you to upgrade to FWH 7.10

[James Bott]

Ramesh,

Try this:

Code: Select all  Expand view

oClipBoard := TClipBoard():New( CF_BITMAP )
oClipBoard:Open()
hBmp := oClipBoard:GetData()  // Get handle  bitmap
oClipBoard:Close()
hDib := DibFromBitmap( hBmp )      // Write from handle
If Empty( hDib )
   MsgInfo("Can't make a bitmap","Error")
   RETURN
EndIf
DibWrite( "BmpFile.bmp", hDib )
GlobalFree( hDib )
DeleteObject( hBmp )

Mr.James

Thank you very much for your support.

Actually the DibWrite(...) function it self not functioning properly.
It is generating a BMP file with only 14 bytes !. I have tried several
ways including yours.

Still the same problem.

Thank you once again.

Ramesh,

Please copy here the source code of your FWH DibWrite(), thanks

[RAMESHBABU]

Mr.Antonio

Thank you very much for not leaving me in vain.

Code: Select all  Expand view

BOOL DibWrite( LPSTR szFileName, HGLOBAL hDIB )
{
   LPBITMAPINFO Info = ( LPBITMAPINFO ) GlobalLock( hDIB );
   void huge * Bits  = ( void huge * ) ( ( FARP ) Info + Info->bmiHeader.biSize +
                       wDIBColors( ( LPBITMAPINFOHEADER ) Info ) * sizeof( RGBQUAD ) );
   long lSize = GlobalSize( ( HGLOBAL ) Info );
   BITMAPFILEHEADER bmf;
   int hBmp;

   bmf.bfType      = 'BM';
   bmf.bfSize      = sizeof( bmf ) + lSize;
   bmf.bfReserved1 = 0;
   bmf.bfReserved2 = 0;
   bmf.bfOffBits   = sizeof( bmf ) + ( FARP ) Bits - ( FARP ) Info;

   #ifndef UNICODE
   if( ( hBmp = _lcreat( szFileName, 0 ) ) != HFILE_ERROR )
   {
      _hwrite( hBmp, ( const char * ) &bmf, sizeof( bmf ) );
      _hwrite( hBmp, ( const char * ) Info, lSize );
      _lclose( hBmp );
      GlobalUnlock( hDIB );
      return TRUE;
   }
   #else
   if( ( hBmp = hb_fsCreate( ( unsigned char * ) szFileName, 0 ) ) != ( int ) INVALID_HANDLE_VALUE )
   {
      hb_fsWriteLarge( hBmp, ( unsigned char * ) &bmf, sizeof( bmf ) );
      hb_fsWriteLarge( hBmp, ( unsigned char * ) Info, lSize );
      hb_fsClose( hBmp );
      GlobalUnlock( hDIB );
      return TRUE;
   }
   #endif
   else
   {
      GlobalUnlock( hDIB );
      return FALSE;
   }
}

//---------------------------------------------------------------------------//

CLIPPER DIBWRITE( PARAMS )  // ( cFileName, hDib ) --> lSuccess
{
   _retl( DibWrite( _parc( 1 ), ( HGLOBAL ) _parnl( 2 ) ) );
}


Please look into it and suggest me, if any thing is to be modified.

Thank you once again,

FWH 2.8 (Sep Build) + xHarbour 0.99.71 (Simplex)

It seems identical to the one in the current FWH release.
