Use global or class variables to determine if message is already on screen.

I guess I solve your problem? Unsure | :~

How to get time difference in seconds.

CTime t1;
t1.GetCurrentTime();

after some time say after 3 seconds
CTime t2;
t2.GetCurrentTime();

Now I want difference between t2 and t1 in seconds that is 3 seconds;

Instead of all the above use

DWORD dwStartTime = GetTickCount();<br />
<br />
//Some Code<br />
<br />
DWORD dwStopTime = GetTickCount();<br />
<br />
Now the Difference ( dwStopTime - dwStartTime )

gives u the required difference in Seconds

NiceNaiduNow the Difference ( dwStopTime - dwStartTime )

gives u the required difference in Seconds

I think this will return the difference in milli seconds..

Yes .u r right.
U will get the time difference in milli seconds.
Divide the difference with 1000 to get Seconds.

Thanks for the correction Naveen.

In MFC, use subtract operator and CTimeSpan class:

CTime time1 = CTime::GetCurrentTime();
::Sleep(3000);
CTime time2 = CTime::GetCurrentTime();
CTimeSpan diff = time2 - time1;
LONG seconds = diff.GetTotalSeconds();

Note the usage of CTime::GetCurrentTime static function.

Wrong. Use this instead:

t1 = CTime::GetCurrentTime();

If u want numbers between MIN to MAX,

Use

rand() % (MAX- MIN+ 1) + MIN ;

rand is limited to RAND_MAX value which is 32767, so with your technique, it won't work.

What I did when I wanted to have bigger number, was just adding the results of two rand. So, if it is up to 65000 this technique can work also.

But this does not ensure unique rand number.

If in one case : rand1 = 12345 , rnad2 = 3; randResult = 12348
If in the other case : rand2 = 12344 , rand2 = 4;randResult = 12348;

there is no guarantee of getting unique numbers.

There should be some other mean for getting rand numbers.

Hope I am not boring u Cerdic.

thank u,
by using this we get the points with respect to window not with respect to mai window.
i used this code

GetCursorPos(&cp2);
	 CProfileWindow MyWindow;
 HWND Hparent=GetParent(MyWindow);
 ::	ScreenToClient(Hparent,&cp2);

in this we are getting HWND null so that it is not considering main dialog it is giving with respect to window,
please urgent,

See the Syntax of GetParent(),It takes HWND as paramter,

So , Do this

<br />
CProfileWindow *pMyWindow;<br />
HWND Hparent=GetParent(pMyWindow->m_hWnd);<br />

Which means you should call GetCursorPos() before calling DoModal() to bring up the second dialog. Pass the coordinates to the second dialog in the class' constructor or some "setter" method.
