oGraph- how to save into bmp in silent mode

[Otto]

To all,
I use xBrowse as a preview for a report.
Now I would like to print this report.
On each single line I would like to print the corresponding graph.

Does someone know how to convert oGraphs in silent mode to bmp.

Best regards,
Otto

I assume you are using the TGraph() class. If so, it has a Save2Bmp() method, have you tried that? I haven't tried it but I don't see anything that make it to be not silent.

METHOD Save2Bmp( cFile ) CLASS TGraph

LOCAL hBmp, hDib
DEFAULT cFile := "TGraph.Bmp"

hBmp := WndBitmap( Self:hWnd )
hDib := DibFromBitmap( hBmp )
DibWrite( cFile, hDib )
GloBalFree( hDib )
DeleteObject( hBmp )

RETURN ( FILE( cFile ) )

Hello Robb,
thank you for your help.
The method is working.
After a long time I am using again ER.
I have to re-learn the handling and find a workflow for me.
I have also to look into the paint method of oGraph to reduce the margin.
The margin around the graphs consume to much space.
Thanks again and best regards,
Otto

This is the source code for calling the Report:

Code: Select all  Expand view

function printMonatsvgl()
   local oVRD
   local cBmp := ""
   local I := 0
   *----------------------------------------------------------

   EASYREPORT oVRD NAME ".\xVRD\EasyReportExample1.vrd" //;
   //   PREVIEW lPreview TO cPrinter   PRINTDIALOG IIF( lPreview, .F., .F. )

   IF oVRD:lDialogCancel = .T.
      RETURN( .F. )
   ENDIF

   select jahresvgl
   go top
   do while .not. eof()
      I:= I + 1
      PRINTAREA 2 OF oVRD
      cbmp := "BMP" + ALLTRIM(STR(I))+".bmp"

      if I > 12

         IF oVRD:nNextRow > oVRD:nPageBreak
            PAGEBREAK oVRD
            //        PRINTAREA 2 OF oVRD
         ENDIF

         PRINTAREA 4 OF oVRD;
            ITEMIDS    { 100,110,120,130,140,150,160,170 } ;
            ITEMVALUES {  jahresvgl->MONAT    ,;
            transform(jahresvgl->JAHR      , "@E 9999,999" ),;
            transform(jahresvgl->DIFF_J_1   , "@E 9999,999" ),;
            transform(jahresvgl->JAHRMINUS1 , "@E 9999,999" ),;
            transform(jahresvgl->JAHRMINUS2 , "@E 9999,999" ),;
            transform(jahresvgl->JAHRMINUS3 , "@E 9999,999" ),;
            transform(jahresvgl->JAHRMINUS4 , "@E 9999,999" ), cbmp }

      else
         PRINTAREA 3 OF oVRD;
            ITEMIDS    { 100,110,120,130,140,150,160,170 } ;
            ITEMVALUES {  jahresvgl->MONAT    ,;
            transform(jahresvgl->JAHR      , "@E 9999,999" ),;

            transform(jahresvgl->JAHRMINUS4 , "@E 9999,999" ), cbmp }

      endif

      skip
   enddo

   oVRD:End()

   select jahresvgl
   go top
return nil
//----------------------------------------------------------------------------//

Hello,
please see how nice xBrowse and EasyReport are working.
Frist you see a report-live-preview. The user can add and delete subtotals wherever you need in your report.
Then you can print the report including the graphs.

Best regards,
Otto

In the spanish section of Easyreport forum they're making great progress and building an awesome product.

Otto Good afternoon, thing is, I need to create graphics in silent mode and then print a report on EasyReport , by chance you have an example of how. I'm using the tgraph .

At this point I think a dialogue to show the image, but it only works when the dialog is closed.
This is the function .

Cheers

Otto,

I am not sure exactly what you are trying to do, but if you need to draw the graph, then save it to a bitmap, then you probably can draw it on an invisible window or dialog, then save it and end the window or dialog.
