How to change font of Cdialog programmatically ?

I use Create(IDD, CWnd*) function.

thanks.

Add a CFont member variable to the dialog's declaration. In the dialog's OnInitDialog() method, use:

LOGFONT lf = {0};
lstrcpy(lf.lfFaceName, "Arial");
m_font.CreateFontIndirect(&lf);
SetFont(&m_font);

Your method is not work,

also
virtual OnSetFont(Font*) - for settinf font,
not works.

Works:

Problem now- how to acces private members of CDialog,
if I want to create reuseable class for CDialogs
for font change ???

My apologies. The code snippet I provided was from a project in my archives. Those are from many years ago and apparently do not work with newer versions of MFC.

This is a file only accessible by you. From what I could find CodeGuru has no such article.

The dialog itself can access all members, regardless of their privilege.

Code from above article do not work for ActiveX,

do you know how to correct it for that purpose?

CFont *font = new CFont;
font->CreateFont(14,0,0,0,1200,0,0,0,
ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,
DEFAULT_PITCH|FF_DONTCARE,"Arial");

m_example.SetFont(font);

the first number is the size. play around with the numbers for your liking.
I have a class called label.cpp label.h if you need it. It makes 3d fonts and all. Send me an email to junkmail4tony@comcast.net with a subject line of would like label class files. I will happily send it to you.

It sounds like the .ocx file has not been properly registered. You can register it with the regsvr32.exe program.

Hello,

i have a little problem with the interpretation of CreateNamedPipe(...)
what exactly is the difference between the dwOpenMode flag FILE_FLAG_OVERLAPPED and the dwPipeMode flag PIPE_WAIT, and which of those is used if both are specified?

Thanks in advance!!

One relates to the calling thread, while the other relates to the pipe itself.

Out of virtual memory

Hi all!

I have a question regarding the computer's virtual memory.
I am writing a program to simulate all kind's of combinations of a poker hand. To do this I wrote 5 while statements. This will give a complexity of about O(50 exp 5) = O(312 500 000) in the last while statement I will do some calculations. The problem is that when I run the program a run out of virtual memory ( I have increased the limit to 4GB ). I am confused why I run out of memory, I did't think the while statements would consume any memory (almost) Confused | :confused:

. Could it be that I have a memory leak in the calculations that I make.
So I guess my question is; will these while statements use all the computer's virtual memory depending on the complexity?

Thanx!

Not possible, even if you were using Windows 2000 AS or DS with the /3GB switch.

No, while statements do not use memory in the quantity you are asking.

It sounds like you need to open the Performance Monitor when your program starts and watch its memory consumption.

Are you allocating any memory in these while loops ???
You need to check ur system performance.
Is there any considerable amount of harddisk space left ?

Thanx for your answer.

I do call a procedure in the last while statement wich is using pointers. So I'm afraid I do not delete these pointers properly.
While I check the system performance I can see that I use more and more virtual memory. It stops at about 2.1GB (all used) and then fills the RAM. Thereafter the program crashes.
I do have about 100GB frre space on the hard drive.
I talked to a friend and he proposed that I should use case statements instead. What would be the differense?

Properly or not, are you deleting them at all? Remember that every new must have a matching delete.

Instead of what? The switch/case statement is synonymous with the if/else statement.

Sorry, I meant do/until.
I do delete all pointers as far as I can see.
Is there an easy way to debug the program and see if there is a memory leak?

if you use MFC you can just run your app for a short
time with the Debuger attached, then exit it
and in the debug-output-window you should see
your mem leaks
