I think that you are having a problem in the way you are thinking and asking.
Soln:
m_datetime is the datetime control.
Now when the user modifies the date in the control you can use the following code to get the date that the user had selected in the control

    m_datetime .UpdateData();
char *str=new char[100];
m_datetime.GetWindowText (str,10);
    AfxMessageBox(str);

// str has the date.
//Extract the date from str and now continue.
Now are you able to get the soluction or some other problem

Somethings seem HARD to do, until we know how to do them.

GetDlgItemText(IDC_DATE,jdate)
where IDC_DATE is id of date time picker and jdate store this value

i try this code what as i tel u i use jdate instead of m_datetime then it give errors
m_datetime .UpdateData();
char *str=new char[100];
m_datetime.GetWindowText (str,10);
AfxMessageBox(str);

Please quote the errors. Try to get the values using GetWindowText. I have already tested the code above that i provided you in this thread earlier.

First of all jDate should not be a string . It should be a control variable for the date time control. Create it using the class wizard and don't take it as a value take it as a control

Have a look at my previous post carefully. You will find that the variable m_datetime should be a control variable and not a string type variable and then use the code provided in the previous post

How to copy from CBitmap to CBitmap

Your original question was about formatting a date to store in a database table. I showed you how to format the date. I assumed you already knew how to store data in the table. What about "displaying" are you wanting to know?

I have two objects: CBitmap bmp1, CBitmap bmp2. There is a sample picture in the bmp1 and the same picture in the bmp2.
Now, I get a copy of the part bmp1 and put it to the CBitmap bmp3. But I don't want to create another CBitmap object. I want release bmp2 interior and put there the new part of the picture wchich is in the bmp3. How can I do it. I can't do bmp2 = bmp3, there is no function like: bmp2.Assign(bmp3).
What can I do?

if you want to copy bmp3 to bmp2 you can use :
bmp2->Canvas->Draw(0,0,bmp3);

I believe Poster is refering to MFC:: CBitmap (Though MFC is not a namespace)

Please, give me a suggest:
How can I get a HBITMAP, when I have only CBitmap bmp3?
I found an example:
HBITMAP hBitmap = (HBITMAP) ::LoadImage (NULL, lpszPathName,
IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);
But, my bmp3 is not from a file.

if you have CBitmap you can use bmp3.m_hObject

I wrote a class in MFC (MyClass : public CWnd), in this class I have a field
CBitmap mBitmap; // not a pointer
I set the bitmap using method:
SetBitmap(UINT nIDResource)
{
return m_Bitmap.LoadBitmap(nIDResource);
}
But now I want to set the bitmap using:
SetBitmap(CBitmap *pBitmap);

I don't know how to assign (change?) CBitmap *pBitmap to CBitmap mBitmap.
This is only a practice, but I want to understand it.

Regards
