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.

please urgent,

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,
sree.

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.

Put this code in OnInitDialog function of your Dlg Class if you are working on a MFC dialog based application
HICON m_hIcon = (HICON)::LoadImage(AfxGetResourceHandle(),
MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON,16, 16, 0);
SetIcon (m_hIcon,false);
ModifyStyleEx(0, WS_EX_APPWINDOW);
Somethings seem HARD to do, until we know how to do them.

You also need to destroy the icon by calling the DestroyIcon(HICON ) to prevent resource leak .

Yeap buddy,
Sometimes the code given is not optimized.
This was one of those.

When I delete an array of objects I got 'Invalid Address specified to RtlValidateHeap' when compiling with debug info.
When delete[] is run in debug mode it calls _CrtIsValidHeapPointer(...) and it fails.
So I dug into my code and after a while I found that if I delete an array of objects it fails ONLY if the objects have a destructor ?
Why don't it work? Im doing something wrong ?
Example.
class CData
{
public:
~CData() { }
DWORD nValue;
};This works of cause.
CData* pData = NULL;
pData = new CData;
_CrtIsValidHeapPointer( pData );
delete pData; This Does NOT Work
pData = new CData;
pData = new CLineInfo[ 2 ];
_CrtIsValidHeapPointer( pData );
delete[] pData;
BUT if I remove the Destructor from the CData class. It WORKS !
Strange...

How does it work if instead of
pData = new CData;
pData = new CLineInfo[ 2 ];
you have
pData = new CData[ 2 ];?
|
|
|
|
|
heh That was a typo when writing the message. it should of cause be
pData = new CData[ 2 ];

This error occurs when you alllocate memory in one heap and delete it in another heap.
Check whether both Debug and Release mode use run time library settings are the same or not .

I suspected that too. But if I do new and delete right after each other as in the example.
they are run from the same place.
I tryed changing runtime library too. I Have tested with both /MTd and /MDd but with no success.
and If that was the error. Why does it works if I remove the destructor.
It is that part that is messing with my head..
