Hi all
I'am using these member functions of CDC class to calculate the
monitor size. none of these functions return the correct value.
I need to calculate the exact size of the monitor.
you can also use this function in your PC and try.
double CMonSizeView::CalcSize()
{
CClientDC dc(this);
int width_mm = dc.GetDeviceCaps(HORZSIZE);//width in mm
int vert_mm = dc.GetDeviceCaps(VERTSIZE);//height in mm
//calculate the diagonal length in mm
double d = sqrt(width_mm*width_mm + vert_mm *vert_mm);
d = d*0.0393700787;//convert it in to inches
return d;
}
please give your feeback and suggestions.
thanks and regards
pradish

Why? What difference does it make if you have a 15" CRT or a 21" flat panel? Both of them are capable of displaying various resolutions. What you should be concernced about, if at all, is the resolution of the monitor.

Do the int width_mm and & vert_mm right for
the monitor u are using .
I mean have u tried to calculate the real heght
and width of your screen and compare it with
what u get it in the variables.

You already mentioned this. I asked what the error is that you are receiving. Have you stepped into the Open() method to see what the problem might be?

When I click a tab page I want to be able to set a flag to indicate to the system that this page has been visited.
Something like OnGetFocus(). Does such a funciton or something similar exist?
Basically when a page gets focus it needs to ensure that any activity on its sister page has been saved before it can proceed, so the sister page will need to have set something

Hi
I have done something like that before... the information on the previous tab needs to be save when another tab is selected.. this is what i have done...
1. Create a variable to store the selected tab...
2. Use OnClickTab to find out which is the newly selected tab...
3. Check if different from last selected tab - if true... prompt save and save previous tab...
4. Refresh the information on the new tab...
5. Save new tab selection to variable
I hope this helps...
