hpp files
A header file written in the C++ programming language. It should be in simple ASCII and (depending upon how portably it was written) should be usable on any machine with a C++ compiler. Typically it would be used in conjunction with a C file. Note that the h extension is also sometimes used for C++ header files.
h
A header file written in either the C, C++, Objective-C, Objective-C++, or Inform programming language. It should be in simple ASCII and (depending upon how portably it was written) should be usable on any machine with a C (or C++, ObjC, or ObjC++ as appropriate) compiler. Typically it would be used in conjunction with a c or C file.

HPP files are typically used with CPP files.

Huh? What is the difference between a c file and a C file?

None really. It is just a matter of style. They both can contain the same code.

I made a program with VC++/MFC. The program is for communication with a opc-server (PLS) an is running all the time.
Now I found out in the taskmanager, that the number of page errors is very high. I know, that the page errors are not a really error. This are only the memory-pages which are saved in the virtuell RAM and not in the RAM.
But writting the memory-pages to the virtuell RAM needs much mor time as handling with the RAM.
So how can I find out which part of my program causes the page errors. How can I prevent the page-errors?

I am using Sleep(n) in my application which is giving me a lot of inaccuracy..almost 50millisec..My Threads call Sleep and so the synchronisation is lost...
this is causing many of my actions to go out of turn and calculations are getting too inaccurate...could anyone please give easy code to replace the Sleep and add it to my code...
Thanks in advance

Which accuracy do you need to have ? If you look for an accuracy under 15 msec (approximately), then you can forget about it. Windows is not a real-time operating system and thus, you cannot have precision under 10 or 15 msec (depends of which version of windows you are using). If you don't need a so much precision but still want to have something better than Sleep, you can have a look at GetTickCount[^]. You'll be able to do something with it.

Use Synchronisation techniques instead of Sleep..
several synchronisation techniques are available here
CriticalSecction,
mutex,
semaphors, etc.
Use appropriate for efficiency and performance.

Create the pointer of the Secoend dialog box into first one and access the elements/Objects through that pointer.
Hope i understood your problem.

Try to make the Variable as extern , initialise it properly before invoking the enablewindow api.

as i make variable of edit control of the type CEdit how could i make it extern
d.DoModal();
pop->GetDlgItem(m_nemp)->EnableWindow(FALSE);
i take m_nemp as CEdit type and call it but it will give error that undefind in class one

I mean make extern variable of the second dialog box.
access it after initialisation.

Hi gurus,
what is the difference between following statements
int *p[10];
int (*p)[10];
what is the memory structure for both?
How to access the elements?
Thanks in advance..

int *p[10];
it is a two dimensional array and its elements can be accessed as
p[0][0],p[0][1].....
