time_t is defined as __int64 by default!!
How safe it is to declear var with __int32 instead of time_t so that i can get a 32 bit time.

Hi,
I need to pass an array from a DLL to a static lib function in order to be filled (the DLL links against the static lib). Neither lib supports MFC.
Something like:
int* intArray=new int(3);
CallStaticAPI(intArray);//the API will just put 3 ints in the array
//do some processing with the array
delete intArray;
When I try to delete the array, the program crashes. I looked in dbgheap.c and the message I get is :"If this ASSERT fails, a bad pointer has been passed in. It may be totally bogus, or it may have been allocated from another heap. The pointer MUST come from the 'local' heap".
The pointer is definitelly good because I can read from it.
Any suggestions?
thanx

Here you are assigning intArray to be a pointer to a single int that has a value of three, What you want is
int *intArray = new int[3]; You are getting the assertion because when you put 3 ints into the array (which has the size of one) you are generating a buffer overrun.
You may be right
I may be crazy

if there is enough space then also will it get wrapped?
In the DrawText funtion give the DT_WORDBREAK|DT_EDITCONTROL and dont give the DT_SINGLELINE style.

When a single click comes, set a timer with the time greater than the mouse double click speed time. When a mouse double click comes, Kill the timer u set earlier and show the dialog u want.
in the timer handler, First kill the timer and then draw the ellipse.
Hope u understand...?

Hi,
I have created a control type variable for an edit box.My requirement is if I enter anything other than a number , it should display a message.Is there any function available to check whether the entered data is a number or not?(As per my requirement the variable should be only control type but not an integer or double type)
Thanks in advance

derive a class from the CEdit and overide the WM_CHAR message. In that function u can chek the entered character is number or not.

Set the ES_NUMBER style for the edit control.

You have created a menu. The id of the menu would be IDR_MENU1 or something similar to this unless you have changed it. Right click on the dialog. Go to properties and in the menu option mention the id of the menu IDR_MENU1 in this case. Compile and Execute. You will see the menu.
