In addition to Alok's suggestion, you might also look into SetCapture().

I got a sample visual c++ program from disk.I set some breakpoint in the application ,but when i debug this application,I found that the breakpoint is invalid and the breakpoint is removed in the debugging process.Why and How to fix this problem?
Thank you for your answer!

ONLY TWO THINGS ARE RESPONSIBLE
CASE 1
You have placed a break point in loop in which control is not going;
CASE 2
You have placed a breakpoint inside dll;

If option is not set on debug the dll obviously break point becomes invalid. Try doing it

 Is that option is set by default?!

This is because the debugger cannot find the symbols of the DLL they are trying to set the breakpoint in.
They need to goto the Project settins, debug tab and select Additional DLLs in the combo box, you can then specify additional DLLs which will have symbols loaded for them at debug startup. this allows breakpoints to be set in loaded DLLs of a project.
Note: This was written with VC6 in mind
If you vote me down, my score will only get lower

Exactly. With VC++ 7+ you don't have to worry about it.

What often happens is that the source code is not the same version as the code in the application. (is the source compiled into a static link library?)
Find out where you should put the SLL and relink your app.

Did not find a forum for an IDE question... so...
(If there is a better place to post -- let me know.)
Problem:
I make NO CHANGE to any project in the solution, ask for a build and
all projects checked in the solution configuration are compiled. Further,
If I build (all recompile and link) then run a debug test, I always
get the message that the project is out of date and needs to be recompiled.
Please:
What option, where, to get a proper build only recompiles if necessary?
(I have hunted and read docs and find no answer.)
Comment:
I had to reformat and reload recently. My IDE use to work correctly!

I believe that the date-time on your project files is wrong. You may have saved the 'always recompiling files' at a later date than the current system date-time.
To solve the problem, I think you can open each and every source and header file (not icons or images etc) in notepad (one at a time) and press Ctrl+S (Save) on each of them. That way they will be saved with the current date-time, and hence will require no more 'needs to be recompiled'.
this is this.

That seems to have done it! Thank you.

One more case,
If your system date has changed to a date prior to the files date....

In addition to the date/time issue already mentioned, I can think of another way the IDE can become confused: When you alter the place where the build-results of a sub-project are put, the IDE sometimes does not find them and tries to rebuild.
I have switched to make all my LIBs, EXEs and DLLs in the standard 'debug' and 'release'-direcories and use pre-build and post-build steps to copy them where they are needed.

I reloaded to the original location. And I use the default
location (debug). So your suggestion did not apply. But,
thanks for the thought. The first suggestion of load/save
with notepad to correct the system timestamps seems to have
worked.

hi
i am creating a win32DLL(on VS6).
could anyone please tell me what are the files to be included to call the functions in the dll and where?
1)i have created a Win32 Dll file and compiled it "successfully".It created .Lib ,.exp and .dll file(so no probs there)
2)since i have used __declspec(dllexport) i did not create DEF file.
3)i have created a simple win32 console application.the code is as follows:
#include "conio.h"
#include "Flipdll.h"
void main()
{
NumberList(); //these are functions in Flipcode.dll
LetterList();
getch();
}
1)if i compile normally it throws up "cannot open Flipdll.h file", so i copied Flipdll.h into current directory.
2)but now it throws up the error
FlipDllWin.obj : error LNK2001: unresolved external symbol _LetterList
FlipDllWin.obj : error LNK2001: unresolved external symbol _NumberList
Debug/FlipCodeWin.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
I have even copied the Lib file but no use
Plz guide me on this.I saw number of tutorials but all of them concentrate on Creating DLL(most of them MFC but not the basic settings like inclusion of files which are essential for a beginner.
even code project doesn't seem to have good beginner tutorials
Any kind of help will be highly appreciated

hey i copied the lib file and dll into the current working directory, and also included path of lib file in project->settings and it worked
but the problem is that whenever i update the Dll file i need to copy the lib and dll files again.isn't it a tedious process??
is there any other way without copying these 3 files(.h,.lib and .dll)??

I cant remeber exactly because I dont have vs6 on my pc.
In the project properties dialog you can enter folders to search for header and lib files. Put the relative path from your client project to the folders containing the .h and .lib files.

The simplest way is to write a Prebuild Event step that copies the .lib and .dll files.

How to write a Pre-Build event step??Any Links?

1. Open the project settings dialog and go to the pre-build tab, there you can write a command like "xcopy ${target} ..\DestinationDir" (consult the xcopy help for the exact syntax)
2. About the link problem: you may add the *.lib of your dll to the libraries your project depends on, this will cause it to be statically linked (loaded when your program loads), you can find more info on MSDN (like dynamic linking with LoadLibrary)

Cut that out, that'd be too complex. Just include the .lib in the Libraries path in Project Settings.
