C++Builder: Getting page width and height

Hi,

My boss forced me to do everything the VCL way now, and I had to rewrite a complete printing routine that I wrote using Win32 code. My Win32 code used MM_LOMETRIC as mapping mode, so I could easily specify where I wanted things, and so it would print the same, regardless of the DPI of the printer. With my VCL version I pulled the same trick, but not using VCL functions, since TCanvas doesn't seem to provide a way of setting mapping modes. So I did it this way:

SetMapMode(pCanvas->Handle, MM_LOMETRIC);

TPrinter gives the page width and height nicely, and the help says that VCL automatically starts a new page if you draw text beyond the bounds of the page... but all this doesn't work right anymore (I fear it's cause of my manual setting of the mapping mode). If I draw a line that should be the width of the page, minus a margin on the left and right sides, then I get a line that starts nicely at the margin, but goes on and on as if the page is 2 - 3 times wider than it actually is. And also, if I draw text lower than the page height (umm.. that is... draw below where the page ends), then it just gets chopped off, no new page is started. This leaves me without some important information, the width and height of the page. If I can somehow calculate those, then I'm happy, and I don't need VCL to start a new page for me, I can do it myself. So my question(s) would be (I guess):

- Is there a way to set the mapping mode with VCL functions? (I passed TCanvas to my print function instead of TPrinter, cause I need to use the same function for previewing)
- If there isn't, is there a way I can still get the proper page width and height? (Maybe perform some calculations on the width/height values TPrinter gives me?)

Thanks in advance,



Paul
