Maybe like this:
const char * const s = "2006-06-12" ;
int year, month, day;
sscanf(s, "%i-%i-%i", &year, &month, &day);
CTime const t(year, month, day, 0, 0, 0);
m_cMyDateTimePicker.SetTime(&t);

It was just a sample.
In your application you probably get date from database with a SELECT statement, let us say "SELECT id, name, date, count FROM myTable" (this is just a sample). Then you use mysql_query and finally something like res = mysql_store_result(myDB). Now you can access the date value, which is the third field of the statement:
char * s = row[2];
Put a breakpoint here and see if the date value is valid. Then use the previous sample to display it.

First try hard-coding your SQL statement. i.e select * from empinfo where empid = 111 and see if it works. Mostly the bug sits in the way we assemble the string. And if the hard-coding works fine, try to make your sql string and before excuting it, Display it in a message box or in a CEdit so that you could verify that you are passing a well formed query string. Or you can also set check points to see the string.

ok...
I think the problem is occuring due to this reason.

if there is any chance of occuring exception????
Please help me...

I think this causes problems if your project’s configuration does not allow multi-threading. You should open the project’s properties dialog and be sure that the C/C++ --> Code Generation --> Runtime Library option contains a right value related to multi-threading. Then rebuild the application.

Thank you...
I don't know it will work or not.
Let me check.

May one thread still be accessing the memory you just deleted?
Maybe using smart-pointers (like those from boost.org)[^]can help you?
Or at least an object which can delete itself via a member function?

That's a very clear description of the problem 
The solution is: you did something wrong.

What is the exact error ?
Maybe your pointer points to an invalid address. You probably left it uninitialized and then try to delete it.

Possible causes:
- un-initialized pointer, like
int * p; delete p; - pointer does not point to an object created with
new: int x; int * p = &x; delete p; - multiple execution of
delete: int * p = new int; delete p; delete p; - pointed zone was altered by other code:
int * p = new int; memset(p-100, 0, 1000); delete p; Note that null value of pointer does not generate exception. This is OK: int * p = NULL; delete p;

In my case the above mentioned 4 cases will not be satisfied.
Actual reason is any other.:->
And also as per ur comments
int * p = NULL; delete p;
how the datas will be deleted from the location which is pointed by p initialy.
since u r saying to delete the pointer after asigning the pointer to null.

he doesn't say it is the things to do...
the cases enumerated are possible causes for a crash when deleting a pointer

That's probably your problem. When you do this:
int* pTest;
if (pTest)
delete pTest;
You will have an excpetion because you try to delete memory that is unitianalized (you can only delete memory that has been allocated with new). So, to be sure not to delete this 'unexistant' memory, assign NULL to the pointer. This is safe.

According to documentation (http://msdn2.microsoft.com/en-us/library/h6227113.aspx[^]), “You can [...] use delete on a pointer with the value 0”.
Therefore instead of
if( p != NULL )
{
delete p;
p = NULL;
}
you can use
delete p;
p = NULL;
However, this does not belong to original topic. I think you should put a breakpoint at the line where your block of memory is allocated and the pointer is assigned. Then investigate the pointer’s value and the content of the memory block. Then stop on the line where the pointer is deleted. Check if the pointer contains right address value. Try to use step-be-step execution during deletion. Perhaps the pointer points to an object having destructor, and the problem is within this function.
