Thanks for the link. Some useful fundamental stuff in there.
But a tutorial on using shared C++ libs in eclipse, from start to end and cover things like: which header files to put where? - which project reference to select, which directory structure to use, etc would be good. (Just a simple example would be amazing)
This one here comes close: http://janmagnet.wordpress.com/2007/09/30/eclipse-cdt-and-shared-libraries/[^]
I followed that tutorial exactly and still I simply get a "make: *** [WLFeeder] Error 1, Type: C/C++ Problem " problem ...
Double-clicking it doesn't do anything, no more info, thats it.
If someone who knows how to use CDT in eclipse can make one project reference another (containing a class that needs to be used)
it would be really really awesome. I'm left stumped.

ok found the problem: was using shared instead of static library!
thanks guys for your help!!

Hello,
I need to make a message loop that (also) ends when an event is signaled. I could probably do it myself, but I know messing with message  loops is a tricky thing. If you could point me to a resource, where someone has already done this and ironed out all the potential bugs, I'll be grateful.

My application freezes after my while loop is in effect. The thing is everything in the while loop executes while the gui remains frozen and windows saying the application is not responding. Cpu usage is at 3% and its still executing properly, its just that the gui is frozen! I cant click my button which resets activeR to false thus ending the loop!
I first tried a simple Sleep(5000) at the end of the while loop, but that ended up with 100% cpu usage.
So i looked up on t_time and worked this out... like i said, it works... but the gui freezes. It still executes the keypress every 5 seconds though.
void roger()
{
int count = 5;
time_t seconds;
time_t curseconds;
bool seq = false;
curseconds = time (NULL) + count;
while(activeR){
if(activeR && seq){
curseconds = time (NULL) + count;
numRogers = numRogers + 1;
keybd_event(VK_PRIOR, 0xc9, 0, 0);
keybd_event(VK_PRIOR, 0xc9, KEYEVENTF_KEYUP, 0);
seq = false;
}else{
seconds = time (NULL);
if(seconds >= curseconds)
{
seq = true;
}
}
Sleep(1);
}
}

you need to implement this on a different thread.
your loop utilizes the main thread and thus the UI freezes.
You need to google first, if you have "It's urgent please" mentioned in your question.

As suggested above, you should call this function on a separate thread. If MFC, look up AfxBeginThread.

That was a fabulous way of doing things not only the wrong way, but to also complicate it beyond recognition.
If I haven't misunderstood it seems like what you want to do is synthesize a PgUp keystroke every fifth second.
Use CWnd::SetTimer(), or similar, to set up a timer that is fired every fifth second and call ::keybd_event() from the WM_TIMER message handler.
You do not need a secondary thread for this.

lol it looks like you've answered his call "roger()"  . I didn't actually look at the intention of the code. It looked like it's a strong while loop. So didn't opt for timers. Yep timers can do if that's his requirement.

I didn't think of it that way, but now that you mention it, it is actually a rather funny coincidence.
Good one!

The UI would appear to be frozen because your application is busy processing roger() function. One way (from the book: "Ugliest things to do") is to do the dirty stuff manually, but I said it is dirty.
Put this within your while loop:
MSG Msg;
while(::PeekMessage(&Msg, NULL, 0, 0, PM_NOREMOVE))
{
AfxPumpMessage();
}
I've assumed you're using MFC, if you're not, you can still call up on TranslateMessage and DispatchMessage (which would make it dirtier)
This would manually pump message during every iteration of the loop and your application's UI won't appear frozen. *BUT*, you must do such things on a separate thread, like everyone else said.

Ummm, no, I did not.
In fact I said the opposite based on what it seems like he's trying to do.
His whole while-loop is an attempt to create timer-functionality and "count seconds".
He'd better correct the root cause and use a timer instead of still doing the wrong thing, but disguising it in a thread.

lol I just did the same.. looking at the loop he had put, I just replied him to go ahead with a worker thread.

Hi,
I have created SDI application from CView base class, Now I want to type charactors on the client area. But it was derived from CView so i couldn't get control. So I have created one CRichEditView class object. But i dont know to create the RichEditView for the currently active window. Pls help me
|

Ummm - why not just change your custom view to derive from CRichEditView? You'll also have to replace CView with CRichEditView in various places in your view's .cpp file, for example, in an IMPLEMENT_DYNCREATE statement, a BEGIN_MESSAGE_MAP statement and where CView methods are called (e.g. your view's PreCreateWindow method will call CView::PreCreateWindow - that should be changed to CRichEditView::PreCreateWindow).

Hi,
i'm new to c preprocessor and i would like to do some string replacement in a text file using c preprocessor.
the code is something like this
---
#define __TOREPLACE__ replaced
path/subpath/__TOREPLACE__
path\__TOREPLACE__image.png
---
the output is:
...
path/subpath/replaced
path\__TOREPLACE__image.png
...
as seen, there is a replacement in the first path, but not in the second one.
why isn't the second one replaced ?
is this a good approach at all ?
thanks in advance

Just a guess... But try it with a double \\. In C files, a single \ means the next character has something special about it. Well, it quoted strings it does!
And as your paths aren't valid commands or variable names, I'm guessing you left out the rest of the line and the quotation marks?
