SDI Text

I am trying to put text on a sdi program. here is an example of what I am doing:

CClientDC cdc(this);
CString mess;
mess.format("a message here");
cdc.textout(10,10,mess);

Now here is my problem, it prints it out to the screen, but if another window covers it, the text vanishes, and also if I want to put something else there I have to print out to that spot twice once with a really long empty string and then again with what I want there. Is there a way to keep the text there when another window covers it? And is it possible to have like a Clear Document command of some sort?

Thanks for the help in advance.

You should print the text during the OnPaint event of your window. If you don't have it, use ClassWizard to add it.

I think you can use something like InvalidateRect to clear it all, however that might flicker a bit.

Since I think this is your main view, you would use OnDraw instead of OnPaint, there you already have a device context.
Also you don't have to use CString.format for simply assigning text, you can use the = operator instead (speed!!!). Format is for numbers you want to include in the string.
Example: to get "You have a score of 156" You would use:
string.format("You have a score of %i", iScore)
or something like this.
