	I'm trying to create a metafile from my simple application
	but i have a quite serious problem. When i use the following 
	code :

	brush=CreateSolidBrush(....);
	pen=CreateSolidPen(....);
	hcdMeta=CreateMetaFile("metafile.wmf");
		SetMapMode(hdcMeta,MM_ANISOTROPIC);  	// 1
		SetWindowOrg(hdcMeta,...);		// 2
		SetWindowExt(hdcMeta,...);		// 3
		SelectObject(hdcMeta,brush);		// 4
		SelectObject(hdcMeta,pen);		// 5
		Rectangle(hcdMeta,...);			// 6
			.
			.
		// GDI-calls supported by metafiles
			.
			.
	DeleteMetaFile(CloseMetaFile(hdcMeta));
	DeleteObject(brush);
	DeleteObject(pen);
		.
		.

	...nothing happens in my application when i try to draw it
	nor in the sample 'wmfdcode' that follows Microsoft's SDK 3.1.	
	It seems however that if i remove 1 ( // 1 ), everything works ok,
	though my intension of it all is also removed. I want to scale
	the darn thing, without having to set the mapping mode in
	my application.
	
	Well i looked in microsoft's guidelines to create a metafile
	and it says that you should set a mapping mode in any metafile
	so that they are device independent....
	Howcome my code doesn't work.
	Can anybody help me please!!!

thanx in advance
