That is the WIN32 API routine. The MFC routine when used inside of a class method just takes the rect as the single argument.

Got it! So MFC sort of knows which is being used - the API one or thh CWND one.

use
GetClientRect(&rect);
You must to be ussing the MFC class version.
If you want to use the WINDOW version mas to use
::GetClientRect(this,&rect);

Finally, you use an & in the argument, and MSDN says just the rect, no &......it compiles either way. Which is right?

read(anything MSDN, book, C++ standard) about c++ scope resolution operator.

Depends.
If you use a variable type RECT you must to use & becuase you must to use a long pointer to RECT LPRECT
for example
RECT rc;
::GetWindowRect(hwnd, &rc);
or
LPRECT rc;
::GetWindowRect(hwnd, rc)

I have a modeless dialog that can be stretched. If I want to know its height and length how do I get this? If I have a button on this dialog and want its dimensions hwo do I ?
I'm reading about GetCLientRect and GetWindowRect but am not sure how the functions know whose dimensions they are getting since both take the rect structure as arhgument but arent told which object they are getting the measurements for....
CWnd::GetWindowRect
void GetWindowRect( LPRECT lpRect ) const;
Appreciate your help,
ns

You can do the following:
CRect rc;
GetWindowRect(rc);
int Width = rc.Width();
int Height = rc.Height();
Also You can use GetWindowPlacement();
If you want to resize the Dialog, you mas to use The MoveWindow Function then of put the correct values into the CRect class...
Best Regards

I'm not exactly sure I understand you correcly ...
GetWindowRect : Gets the window ( your dialog ) size in window coordinate, from the parents point of vue, top left relative to the parent.
GetClientRect : Gets the client window ( your dialog ) size in local coordinate, usually the inside of the dialog; the top left is (? ) 0,0.
They get the size of the current object's scope.
void MyDialog::DoSomething()
{
CRect Rect;
GetClientRect( Rect );
this->GetClientRect( Rect );
GetWindowRect( Rect );
this->GetWindowRect (Rect );
}
or from the dialog caller :
...
myDialog.GetWindowRect( Rect );
myDialog.GetClientRect( Rect );
GetClientRect and GetWindowRect work for any CWnd classes.
Max.

Ah! MAny thanks. SO I guess I shouldnt be trying to use the GetCliuentREct in mSDN that has two parameteers.....
Thanks

GetWindowRect returns the location of the whole window on the screen. GetClientRect just returns the client area inside of the window. For most windows, the client area rect will look like (0,0)-(w,h) where w and h is the width and height. To be 100% correct, to get the width and height of a rectangle from a rect in the form of (l,t)-(r,b) would be width = r-l and height = b-t.
But since dialog boxes usually contain border, the size of the rect returned by GetWindowRect will be larger than GetClientRect.

I'm slowly building an interpreter using flex and bison, but it's starting to look like the only input method bison supports is through C-style FILEs (either opened explicitly or stdin).
Does anyone know if it's possible or reasonable to have bison parse input from an arbitrary string in memory? If so, can you point me at a resource that might describe the technique?
PS I have yet to read the manual thoroughly since I'm not to the point where I need to reroute input yet... If it's plainly in the manual, just call me an idiot and I'll figure it out myself.

As usual, I figured it out myself. Turns out there's a whole section on it in the book I have.

What's more important is that we do need to teach people (even if by LARTing) to read the documentation before going public with their ignorance.

Your blunt replies have finally fallen on accepting ears.
I notice you have striven, throughout most of your recent posts, to point out other peoples' ignorance. Not suprisingly, they haven't been very appreciative.
I, on the other hand, pointed out my ignorance before you. I even warned you of it in my initial post. Thank you for reinforcing my claims. I know now that I am truly on the right path.
Now that that's out of the way, might I suggest you reconsider your trolling attempts? Going out of your way to be more condescending than helpful is only going to piss people off, and likely contribute to angst and stress-related illnesses for you.
It's amazing the new world that opens up to you when you stop thinking of others as mere pedestrians, and instead look at them as fellow humans.
I wish you luck in your journey.

At least I try to help the ones asking to help themselves instead of serving the answers on silver plates, which teach them nothing but "if I ever have a question, I won't bother to even look it up in the documentation since I can always bug it out of someone else".

Then you have seen something that's never been my intention. My intention has been, however blunt (depending on the level of percieved stupidity, obviousness, or even time of day) to make those people first search for answers that are (as I have sometimes pointed out) available in either MSDN or on Google.
It is expected (by me, and many others) that someone asking a question that has an answer (i.e. not to spur a discussion) on a message board, in a newsgroup or any other publicly available "board", has first done its own research.
I'm sorry this matter has affected you in such a negative way, but I stand firm in my opinion that people should first search publicly available sources of information.
I wish you luck in your journey.

Nah, just blunt.
Upon re-reading my reply, I'm forced to admit I was in an odd place that day.
I have worked with people from both ends of the spectrum. Some who simply cannot think for themselves (take the guy in the next cubicle - please - "How do I print from Visual Studio?"), and others who just refuse to take advantage of someone else's experience. And while I resent (and I resent the resentment...) helping the doofuses (doofae?) out, I'm not sure that flat-out beligerance is the solution. At least it isn't for me.
I guess it comes down to giving the querent the benefit of the doubt. In the situation with the printing question, given that this wanker insists he's been programming for 10 years, it's clear he's a bit of an idiot and deserves no sympathy. I quietly explained, "Same as every other Windows app." and let it go. But in other situations, it's not always cut and dry.
Take my question, for instance. I had been tweaking my yacc grammar for a few days, periodically going to my reference manual and the online tutorials. All such reference material (save the one small section I later found) assumes input comes from files. And since the tool is really for building compilers and makes it easy to build command line applications, I was curious as to the number of hoops I would have to jump through to route something other than a file through the parser. I had looked through a fair amount of reference material, and just hadn't come across an answer.
Sure, I didn't explain this in my question, and sure I didn't read ALL reference material, and so I can see how ignorance might be assumed. But I like to think I know what I'm doing. I've written a few articles here. I've helped out from time to time in the forums. I'm quite willing to toot my own horn...
Now that I think about it, I guess I made an incorrect assumption as well. I assumed that the person replying would recognize my name and assume I wasn't being a complete slack-bag.
I guess I just got a little incensed that you assumed ignorance. No worries. As I might have mentioned, I tend to do the same. Trying to break myself of the habit though...

To (again) quote a movie: "Assumption is the mother of all fsck-ups".
Also, the fact that you posted your question, and then just five minutes later posted that you found the answer, displayed to me what the same thing probably would have displayed to you. Only this time, the error of assumption was mine.
Well, no harm done. Except, we both know we still need a better parser generator!
I've been looking at both PCCTS and ANTLR, and even that ANTLR actually looks pretty good, it seems it still only support Java as host language. Too bad, since all other of its ideas seems to be quite good.

Actually, I'm starting to lean towards reusing an existing language. I've scaled my project back to the point where I'm just doing some minor scripting and automation for a tiny little utility. I get the feeling that if I follow through with my own language, my parser and interpreter VM will be 80% of my code...
Ever seen Lua[^]? I'm in love...

I've actually, and this surprises even me since I've at least tested many other scripters, including cint (the C/C++ intepreter), never even tried it. The last project needing a scripter ended up using csl (not my decision, even that I put no value in the decision) which allowed C-like code calling back into native both C and C++ code.
I did however read about LUA in an old CUJ (I think) a bunch of years ago. Maby now is the time to actually test it...

I am beginning to use visual c++.net standard and was wondering how to make a menu button open a different program. Plus does anyone know of a good beginner's resource for visual c++? I'm trying to learn but don't know where to start. Thanks.

Under the code that handles the event (i believe it does it if you double click or choose CLICK from the drop-down menu (i have VC++6, little experence with vs.net  ):
(32>= (int)ShellExecute(NULL,"open", "Program To Open.exe",NULL, NULL, SW_SHOWNORMAL));

I'm working on an MDI application with multiple toolbars and I want to load and save the toolbar states to the registry. However, when I check the registry, I can see that it does store some toolbar state info to the registry, not all of it is being written correctly. Each toolbar's position and docking and so on are saved but most of the entries all use the same value for BarID#. While I can find the position and docking data for each toolbar in the registry, the unexplained use of the same BarID# means that only my first toolbar is affected by LoadBarState().
How do I get SaveBarState() to use different values for each BarID#?

I know this forum is for *Visual* C++, but I don't see a forum here for C++ questions with regards to other platforms. So I apologize for offending anyone.
Anyway, one of my company's customers wants us to port some software to Linux. The only real problem I see is that the software requires inter-process mutexes or semaphores. Linux does not natively support named mutexes or semaphores.
I am looking for suggestions about how to solve this problem. Is there a way to create inter-processor mutexes or semaphores (preferably named) with Linux without having to modify the kernel?
Thanks!
- Kevin

Yep, it does, Linux supports the standard SysV IPC functions which allow inter-process semaphores, shared memory, etc (IPC = Inter-Process Communications). Likewise, pthreads allow you to define system-wide semaphores and mutexes. Either of these should do the trick. Take a look here for IPC info, and here for pthreads info.
