Hi, I have a dialog with a couple of textboxes on it, and I want to change
the font size on one of the terxtboxes. I can't seem to find out how. Any
input would be great. Thanks

Have you tried SetFont?
void CMyDialogClass::SetTheFonts()
{
m_fntBigFont.CreatePointFont(24, _T("Arial"));
m_fntLittleFont.CreatePointFont(6, _T("Arial"));
m_edtBigEditControl.SetFont(&m_fntBigFont);
m_edtLittleEditControl.SetFont(&m_fntLittleFont);
}

I have created a mfc project and within this I have created a dialoguebar and multiple document view windows. When I click on a button on my dialoguebar how can I get the current document object as it has a Carray object which I would like to obtain.
Thank you in advance.

That depends on where you are handling the button click. If the dialog bar is part of the main frame class, you can try:
CMainFrame::OnPressMyButton()
{
CMDIChildWnd *vpChildFrame = MDIGetActive();
if (vpChildFrame != NULL)
{
CDocument *vpActiveDocument = vpChildFrame->GetActiveDocument();
if (vpActiveDocument != NULL)
{
DoSomeStuffWith(vpActiveDocument);
}
}
}

Hi. I am writing a dll that attaches to a program with no debug info. When I set an breakpoint in my code it does not stop at the breakpoint, it just ignores it and continues on it's merry way. If I put in __asm int 3 to force a breakpoint, it works and puts me in my code at the int 3 line. This is my second DLL where this problem has crept up.
Does anyone know why the visual c++ breakpoints are broken? (pun intended)
Thanks,
Clint
PS. If you were going to ask. Yes, I am in debug mode with my code.

I always thought breakpoints were disabled in release mode.

How have you got the debugging session configured?
I assume you have the DLL as the loaded project in VC and are using the exe as the "Executable for debug session".
This should work providing you have the dll compiled with the debug info.

Well I gave up trying to figure out why my application wouldn't break, so just made a new project and copied all my exisiting code into it. Everything seems to work fine. One thing that I did change is the DLL name. I had wanted a specific name so I renamed the dll. The new project is named the same as the dll and this works fine. I am curious if this is a known issue because with another dll, it is being renamed as well and I can't set bp's in it either....
Cheers

which one is "better"?
i know bool is more standardized but BOOL is more efficient, but which one is more commonly used, furthermore, which one should i use?

You answered your question. I think that is better to use the more efficient...
Do you prefer to use while(true) or for(;;)?

while(true) and for(...) take the same amount of time. I have yet to see a compiler not optimize while (true) away.

I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Is bool less efficient? I don't think so...
I usually use bool for pure C++ logic, and BOOL for UI/Win API related stuff.
I have seen a lot of people mixing them and IMHO is not a good idea in terms of readability.

BOOL edges out bool in performance just by a very tiny amount.
Here are the rules I use.
If I am doing WIN32 code, I use BOOL. Otherwise, for the other 90% of my code, I use bool.

Hi!
Try this:
bool test_a = 3;
BOOL test_b = 3;
or that one:
bool test_a = true;
switch(test_b)
{
case 4:
break;
case 5:
break;
}
and the same for BOOL.
You will see the difference
Moreover: sizeof(BOOL) != sizeof(bool) ===> 4 != 1
I use always bool's, but when I deal with Win32 - I use BOOL's.

thanks, so for libraries i make, ill use bool if they're not windows-specific ;D

frst of all, thanks to Bill Wilson for answering my naming conventions post
i realized that many of my classes have Get/Set members for very simple variables like integers or such. it's very annoying to manage these functions as the member variables change data type and name a lot throughout my coding process.
is it good practice to make the member variables just public (and not have "m_" precede them) or is there some easy way to manaage Get/Set functions?
also, if public member variables is the way to go, i'd like to have a pointer class to manage dynamic memory and stuff like that.. sort of like a smart pointer... is there an already existing class that would allow for that or do iu have to make one?
p.s. i tried auto_ptr but it seems that that class only sets the pointer in its constructor

well is there a tool to manage the get/set functions then? im using VC++ 6

Yes, there is a big window where you will find your class definition. Add Get/Set methods there as appropriate.
