What do you mean by "wrong?" What does the code look like?

in the MSDN samples just search for floder named "cmnctrl1"
open the project and in the file "datetime.cpp" replace the function as below
<br />
<br />
<br />
void CDateTimePage::OnDTNotify(NMHDR *pHdr, LRESULT * pRes)<br />
{<br />
CTime ct;<br />
CString st;<br />
<br />
switch( pHdr->code)<br />
{<br />
<br />
case DTN_CLOSEUP:<br />
m_lbNotifyList.AddString(_T("DTN_CLOSEUP"));<br />
<br />
break;<br />
case DTN_DATETIMECHANGE:<br />
<br />
m_lbNotifyList.AddString(_T("DTN_DATETIMECHANGE"));<br />
(m_DateTime.GetMonthCalCtrl())->GetCurSel(ct);<br />
ct.GetMonth ();<br />
m_DateTime.UpdateData (TRUE);<br />
st.Format(_T(" --- %02d/%02d/%2d ---%2d"),ct.GetMonth(),ct.GetDay(),ct.GetYear(),((ct.GetDay())-12 ));<br />
m_lbNotifyList.AddString(st);<br />
break;<br />
<br />
case MCN_SELECT:<br />
m_lbNotifyList.AddString(_T("asdf"));<br />
break;<br />
<br />
case DTN_DROPDOWN:<br />
m_lbNotifyList.AddString(_T("DTN_DROPDOWN")); <br />
break;<br />
case DTN_FORMAT:<br />
m_lbNotifyList.AddString(_T("DTN_FORMAT"));<br />
break;<br />
case DTN_FORMATQUERY:<br />
m_lbNotifyList.AddString(_T("DTN_FORMATQUERY"));<br />
break;<br />
case DTN_USERSTRING:<br />
m_lbNotifyList.AddString(_T("DTN_USERSTRING"));<br />
break;<br />
case DTN_WMKEYDOWN:<br />
m_lbNotifyList.AddString(_T("DTN_WMKEYDOWN"));<br />
break;<br />
}<br />
<br />
}<br />
The code in between the //->---- ... ... . //->-----
is added by me actully according to the theory it should display
the data in the datetime control but it displays a wrong date that
is 12 days before .
I found a solution to directly get the text from the date time control
with GetWindowText ();
but i have to parse it by my self & cannot use the direct function like GetMonth(),GetDay(),GetYear(),etc.

Do you suppose it has to do with the 12 that is being subtracted from GetDay()?

 hi,can you tell me how to use Class matrix in VC++,and will implement so kind of operation like mulitply,contradictorily and so on
|
|
|
|
|
You can use CMatrix[^] class also , it supports all methods and operations you may need while working with matrices.

can you give me some examples about how to use this Class CMatrix,Thank you very much.if you can provide some program about this Class ,you will make me very happy
|
|
|
|
|
Ok I'll try to make you very happy 
#1. Include the "matrix.h" file in you project
#2. Now for example if you want to add two matrices do following :
int main()<br />
{<br />
CMatrix a(3,3);<br />
CMatrix b(3,3);<br />
CMatrix c(3,3);<br />
<br />
for(int i=0;i<3;i++)<br />
for(int j=0;j<3;j++){<br />
a.SetElement(i,j,i+j);
b.SetElement(i,j,i-j);
}<br />
<br />
c = a+b;<br />
<br />
for(int i=0;i<3;i++){<br />
for(int j=0;j<3;j++)<br />
printf("%.f ",c.GetElement(i,j));<br />
printf("\n");<br />
}<br />
return 0;<br />
}
All other operations you can implement similar to this , just take a good look to the link I posted .

Thank you dear Giorgi,it's very kind of you,you are so wonderful.as I go over
the arithmetic of CMatrix,I found some of the functions are so abstract to understand.especially,the invert arithmetic is hard to understand,can you describe its idea for me.

With all respect to the previous replies, you certainly do not need to use assembler, and you definitely do not need to use DirectX!
Assuming you are using some Microsoft C variant, you can use the getpixel() and setpixel() functions - look them up in the help files.
To use getpixel and setpixel functions you need an hDC (handle to device context to the window or monitor), etc. Look for examples on the Microsoft MSDN site.

OK, some more information!
I suggest you download and have a look at the Colour Finder application, which is at http://www.codeproject.com/miscctrl/ColorFindercp1.asp[^]
To quote from the article, first a handle to the desktop device context is obtained using the API GetDCEx . This handle is then converted to a CDC class pointer using CDC::FromHandle. Then color is retrieved using the CDC method GetPixel.
I have not looked at the Colour Finder in detail, but it could be a good basis for what you want to do, and it's always easier to start with a working application, even if you throw away large bits (like tracking mouse movement, etc.) and add some bits (like changing the colour at a particular location.)

I want to know what are the differences of Windows NT from Windows XP when in comes to affecting your application. One example is the Windows Directory of Windows NT is WINNT while WINDOWS for Windows XP.
ProcessEntry32's szExeFile works well in Windows ME and below, you'll be able to get the complete path of the file. While if you're using Windows NT and XP, you have to use ModuleEntry32 instead of ProcessEntry32 in order for you to acquire complete path of the process running on your task manager. But of course Its off the topic which covers the difference of NT over XP.
Anything else? Thanx

How will I be able to get the IP address of the computer connecting to me? For example, I'm the server and there are quite a few computers that send files or interact to me. I need to get their IP address for me to use as their ID. I'm using MFC Sockets. Thanx in advance

The second argument of CAsyncSocket::Accept lpSockAddr is the address of a SOCKADDR structure in which you'll get the address of the connecting entity.
