  13.     I'm trying to create a metafile from my simple application
  14.     but i have a quite serious problem. When i use the following 
  15.     code :
  16.  
  17.     brush=CreateSolidBrush(....);
  18.     pen=CreateSolidPen(....);
  19.     hcdMeta=CreateMetaFile("metafile.wmf");
  20.         SetMapMode(hdcMeta,MM_ANISOTROPIC);      // 1
  21.         SetWindowOrg(hdcMeta,...);        // 2
  22.         SetWindowExt(hdcMeta,...);        // 3
  23.         SelectObject(hdcMeta,brush);        // 4
  24.         SelectObject(hdcMeta,pen);        // 5
  25.         Rectangle(hcdMeta,...);            // 6
  26.             .
  27.             .
  28.         // GDI-calls supported by metafiles
  29.             .
  30.             .
  31.     DeleteMetaFile(CloseMetaFile(hdcMeta));
  32.     DeleteObject(brush);
  33.     DeleteObject(pen);
  34.         .
  35.         .
  36.  
  37.     ...nothing happens in my application when i try to draw it
  38.     nor in the sample 'wmfdcode' that follows Microsoft's SDK 3.1.    
  39.     It seems however that if i remove 1 ( // 1 ), everything works ok,
  40.     though my intension of it all is also removed. I want to scale
  41.     the darn thing, without having to set the mapping mode in
  42.     my application.
  43.     
  44.     Well i looked in microsoft's guidelines to create a metafile
  45.     and it says that you should set a mapping mode in any metafile
  46.     so that they are device independent....
  47.     Howcome my code doesn't work.
  48.     Can anybody help me please!!!
  49.  
  50. thanx in advance
