CDatetimepicker ctl formatting

Ashman15-Apr-04 1:14

Hi, I have written a reminders program which allows the user to input something they need reminding about with a date time picker so they can select the date and the time in which the popup should come up....

I need to input into a string the current system time with the same formatting as the control so that the time and dates will match with the times and dates selected by the user. How do I get the System Time in the same format as the CDateTimePicker control?

Code examples would be appreciated or reference to an article.

Thankyou,
Ashley

Hi!
I'm building a application in VC++ .NET.
But when i run it it says to me that it's Out-Of-Memory.
The memory on the computer is not full...

How do you get rid of this problem?
Can you give the program more memory?

Regards, Koo

Are you allocating a large amount of memory?

Is all the memory allocation on the Stack? Or are you allocating on the heap?

Ant.

I don't know. It's windows that allocate the memory so i don't have a clue...

If you have Windows 2000 or XP, look at the Performance tab of Task Manager to see the machine's memory usage. What does it look like before and during the program's execution?

Which makes no sense. Look at the Task Manager before your program runs, write down the memory-related numbers. Look at the Task Manager while your program runs, write down the memory-related numbers. Compare those numbers. What do they tell you?

Ok, can you post the exact verbiage of the out-of-memory message?

It comes in a messagebox:

Sounds like you need to compile in debug mode, and use F5 to start the program.

What I meant was are you allocation memory to data statically or dynamically.

i.e.

char data[1000000];      // Or some large numbers

or

char* pdata;

pdata = new char[1000000];
delete [] pdata;

If you are running through the debugger you should be able to see what it is that is failing to allocate. If you look at the call stack, what is being called?

Ant.

It's a malloc call. Trying to allocate 22 bytes..

If this is a C++ program use new/delete instead.

When you look at the call stack is it calling the same function over and over again?

I.e. trying to allocate 22bytes over and over again?

You may have corrupted the heap.

Usually this is because you've written to an uninitialized pointer, or written before/beyong the end of an array or object that you've previously allocated on the heap.

perhaps the is a better way, but i would subclass all objects
and overwrite the wm_ctlcolor method of each object

for example:

HBRUSH CCtlcoloDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
CBrush *brush = new CBrush(HS_BDIAGONAL,RGB(200,0,0));
return (HBRUSH)(brush->GetSafeHandle());
}

i would declare and construct the brush outside the OnCtlColor Method
