Hi,
I am using VC++ 6.0 . I need to print some text from a simple C program.
How do I do it?
I tried to use fprintf(); but couldn't get a suitable FILE * object to put
as the first parameter.
Please help. Is there any other way to do it?
With best regards,
Sayan

By the word 'printing', I meant printing to a printer.

Oh I see... Well, if you can get by with a simple hack, redirect your standard output to the printer at the command line with myprogram >LPT1: or whatever your printer port is named (go to Control Panel->Printers->Properties->Details.)

You could try this:
FILE* pPrinter = fopen ("LPT1:", "w");
if (pPrinter != NULL) {
printf (pPrinter, "A line of text\n");
fclose (pPrinter);
}

If when you say "print" you mean console, you can use puts(...) or the "stdout" file handle with fprintf(...), fputs(...), etc.
If you mean "printer", you may be able to use the stdprn file handle.

how draw Region border with pen style?
|
|
|
|

I do not think that you will be able to do the border of a region with a pen. The reason is that windows does not actually calculate the border of your region for the FrameRgn function, it simply creates another region and fills that area. This gives the effect of a border.
Of you wanted to you could calculate the border yourself from all of the rectnagles that create the region, but this may be time consuming depending on how complicated your region is. You would have to calculate the convex hull of all of the rectangles, even then, if you have holes in your region, they would be difficult to detect as well.
How are you getting your region?
What are you trying to accomplish with the pen.
Because there are other tools you can use like paths, they are pretty powerful.
If you post a few more details of what you would like, I will try to help you find a solution.

I get region by:
CombineRgn
or
CreateRectRgn ...
or
Create a standard region, then rotate it
Thanks

sorry for replying so late
and thanks for ur suggestion
the problem here is not with rgns i could actually get the desired output on the screen with FrameRgn( , ,1,1);
but when i take a print out i get an image with more width to what i see on the screen
i am not able to under stand the problem
as u suggested paths r powerful but they do not support arcs and ellipses in win 98 platform so i could not use paths for creating aregion o fill the path
thanks for ur help

hello, i have created a CListBox object at runtime on my CEditView. Now i want an event to happen when i click on one of its items. The problem is that at runtime there is no event/command handlers by default (i think). Can someone help me to make an event handler out of my runtime created object?
Thanks in advancee

With the help of the MFC wizard, create a class derived from CListbox doing all the message handling you need. Let's call that CMyListBox. Now, when creating the objetc at run-time, make it a CMyListBox instead and call CMyListBox::Create just as you called CListBox::Create before. If I understood your problem right, this should do.

You need to handle WM_COMMAND and check manually for commands coming from your listbox.

Hello programmers,
i'm blocked on a issue, i've called a CFontDialog dialog and i got the font by assigning dlg.GetFaceName() to a CString variable and now the dlg.GetSize(), used to get font size, returns an integer which i stored in variable size. But now i have to display the font size in a CEditView.... that's where the problem arise.... i cannot convert the int size variable to a CString variable that can be displayed on the CEditView. Can somebody help me convert the int to CString...
i used GetEditCtrl.ReplaceSel() to input the font size on the CEditView but the GetEditCtrl.ReplaceSel() only accepts strings... The code is used is listed below
[ccode]
if(dlg.DoModal() == IDOK)
{
CString text;
text=dlg.GetFaceName();
GetEditCtrl().ReplaceSel(text);
int size;
size = dlg.GetSize();
GetEditCtrl().ReplaceSel(size);
// This is where i get the error message saying cannot convert
// int to CString.
}
[/ccode]

It is simple.
CString s;
int i = 10;
s.Format("%d", i);
// s now == "10"
CString::Format takes the same flags as sprintf, because internally it uses a variant of it. I prefer to use ostringstreams, but as you have a CString, CString::Format is the easiest and most obvious way to do it.
So it's:
CString szSize;
szSize.Format("%d", dlg.GetSize());
GetEditCtrl().ReplaceSel(szSize);

David,
It's right next to the definition of "see sharp".

Actually the real name is ++C. The value of C++ is the same as C, so for this new object-orientated language thingy to be a real improvement, it has to be ++C.
