Why would you want to do this? It would all but totally disable the OS.

Here is the reason:
Say I am testing the speed (I/O reading writting).
I want the Max performance , the code would be like:
tStart = getCurrentTime();
do{
reading();
writting();
}
span = getCurrentTime()- tSpan;
How can I ensure those steps are not interupted?

The first thing to note is that GetCurrentTime() has been deprecated by GetTickCount(). Second, calling SetThreadPriority() with a priority greater than 11 may cause disk caches to not flush, hang the mouse, and so on.

By using a critical section (e.g., InitializeCriticalSection()). I'm not sure you actually want to do this, however.
If you are simply wanting to time a section of code, GetTickCount() is the way to do this. Since Windows is not a RTOS, you'll not ever get 100% accuracy. For example, let's say that, per your watch, the code took 5 seconds to execute. However, span had a value of 6000, or 6 seconds. That means that the code was preempted for a total of 1000 ms. This is not necessarily a bad thing. It's much like weighing yourself at home on a scale that is not 100% accurate. Whether it shows you to be too heavy or too light, it doesn't matter as long as it's consistent. By comparing one weigh with another from the same scale, you can judge for yourself whether you are gaining or losing weight. Make sense?

i need help with input plz
how do i get input for hour and minute if the time is entered as this format hour:min

There is insufficient information to provide you with a useful answer (e.g., how was the time acquired). In a very general sense:
char *pTime = "12:59";
char *pSep = strchr(pTime, ':');
int nHour = atoi(pTime);
int nMin = atoi(pSep + 1);

Hello,
I wonder how to disable the automaic menu enable/disable for CFrameWnd mechanism in eVC 4.0, I thought it could be done by setting the m_bAutoMenuEnable to FALSE?
Am I wrong with that? How can I accomplish it to stop that automatism?
Thnaks a lot...

Thank you, found out myself! It´s always the same: Searching two hours for a solution, then decide to ask the forum, then try again and find solution self within 2 minutes!
Here is the solution: Subclass a CMyMenu from CMenu and overwrite
"void OnUpdateCmdUI(CFrameWnd* pTarget, BOOL bDisableIfNoHndler)"
in this new class.
In this function do nothing, so the automatism doesn´t work.

Hello,
I have a Single Document Interface application generated by AppWizzard. The title bar of the application displays "Untitled - MyApp". I want to get rid of the "Untitled -" so the title bar just reads, "MyApp".
Any suggestions?
Thanks!

go to the resource editor, then check the SDI frame properties and search the caption...
you could also do it at run time with a little SetWindowText() on you main frame...

Right you are! And here I was thinking I'd have to override one of the CDocTemplate methods... I guess I over-thunk this one... lol...
Thanks!

Isn´t it just AfxGetMainWnd()->SetWindowText("MyApp")? Didn´t try, but it´s a suggestion...

Most folks use:
BOOL CMainFrame::PreCreateWindow( CREATESTRUCT &cs )
{
cs.style &= ~FWS_ADDTOTITLE;
return CFrameWnd::PreCreateWindow(cs);
}

CDocument *doc;

Hope this will do.

I'm at a loss for how to correct for a level 4 warning.
header file
void some_func(some_type *ptr, int flag);
source file
void some_func(some_type *ptr, int flag)
{
...
...
}and when I compile, I get
warning C4100: 'flag' : unreferenced formal parameter and yes 'flag' is an unreferenced parameter, so I make the following change
source file
void some_func(some_type *ptr, int )
{
...
...
}and when I compile, I get
error C2055: expected formal parameter list, not a type list
I'm not sure how I have to change the source file, such that I don't get either the warning or the error. Thanks.

You could always do:
void some_func(some_type *ptr, int flag)
{
......
UNREFERENCED_PARAMETER(flag);
}

 I don't use that often enough. Thanks for the quick response, too.

#pragma warning( push )
#pragma warning(disable:4100)
void some_func(some_type *ptr, int /* flag */ ){......}
#pragma warning(pop)
or...
Refactor your code so that the unused parameter is not passed to function in first place

Assumption: 'ptr' or even (the real name for) 'some_type' is declared in a header file (from you or from Windows) and confuses the compiler.

#include "ODBCVER.H"
what is alternation for "ODBCVER.H"of vc6.0 in vc7.0?
can any one please let me know this?
Previously I was using vc6.0;
Now I uninstalled the vc6.0 completely and Installed the vc7.0;
Now I could not run my project. I am getting error as could not open the file "ODBCVER.H".
Please help me.
Nice talking to you.

I think this file was included in VC6 by accident. It appears to contain data used when building the ODBC library (version information to be included in the file version resource data); I can't imagine what you're using this file for but it should not be necessary.

Hi Mike,
Many thanks for giving the reply. Thanks for your suggestion. Now in my project I simply ignored this include statement. Now my project is working as usual. 
Nice talking to you.

Better hook winsockX.dll to see actual command coming and going !
