Like this 
.........
Matrix mtx;
mtx.RotateAt(m_nRotateAnle,PointF((minX+maxX)/2,(minY+maxY)/2),MatrixOrderAppend);
graphics->SetTransform(&mtx);
.....
graphics->DrawImage(m_pImage,rect,0,0,(float)m_pImage->GetWidth(),(float)m_pImage->GetHeight(),UnitPixel);
........

For your project you can use of GDI+ and use of Image::RotateFlip
using of it is easy:
Image m_image(L"c:\\123.jpg");
Graphics m_gdi(need to a hdc);
m_gdi.DrawImage(&image, 0, 0, m_image.GetWidth(),m_image.GetHeight());
m_image.RotateFlip(Rotate90FlipY);
m_gdi.DrawImage(&image, 120, 10, m_image.GetWidth(),m_image.GetHeight());
but did you see MSDN for "Matrix Representation of Transformations" ?

Except english I like two languages Chinese and Italian and I think they are like this: Chinese != Italian
(Chinese is very difficult and Italian is easy (of course for me)).you can see <a href="http://www.google.com/url?q=http://en.wikipedia.org/wiki/Mandarin_Chinese&ei=UvusSfzqM4u4-Qa2hNjYBg&sa=X&oi=spellmeleon_result&resnum=2&ct=result&cd=1&usg=AFQjCNF2qXPRlDhmCxBvWTinPXDu6FSnVA">Mandarin</a>[<a href="http://www.google.com/url?q=http://en.wikipedia.org/wiki/Mandarin_Chinese&ei=UvusSfzqM4u4-Qa2hNjYBg&sa=X&oi=spellmeleon_result&resnum=2&ct=result&cd=1&usg=AFQjCNF2qXPRlDhmCxBvWTinPXDu6FSnVA" target="_blank" title="New Window">^</a>].

I have Created the ATL COM DLL Project and intergrated office
addin with MFc support .
It will create 1 Toolbar button in office . On clicking the button
displaying the messagebox. Working fine. no issues.
After That I just created 1 Dialog and added a MFC class for that. No
Additional code.
Just
AfxSetResourceHandle()
CMyDialog Dlg;
Dlg.DModal();
//reset the resource handle.
Crashing the on the above domodal . after debugging i got the assertion on below line of standard mfc file
if (!AfxGetThread()->PumpMessage())

Return value of this function is NULL or currently executing thread it looks you got NULL as return value so you see this line.

I have created MFC dialog in MFC extention DLL. That Dialog is created and
displaed successfully using domodal in win32 console application with mfc
support and also successfully executed with mfc appwizard executable.
Now I have created Office Add-in using the sample of Comaddin. There I am
calling the same MFC Extension based dialog in that but is crashing after
calling domodal.
I tried to setting the resource handle and instance handle before calling domodal.
Dialog is showing within few seconds it is crashing. After debugging i got the assertion in the following line.
if (!AfxGetThread()->PumpMessage())
The above line from CWnd::RunModalLoop function. This is from default MFC

Hi All,
How to conver CString to char[] in MFC.
In my code:
CString str = "Sample";
I need to convert to char sam[6];
Please help me...........
Thanks and Regards,
Anitha

Did you see here.[^]
First start searching yourself and then ask specific questions.
You need to google first, if you have "It's urgent please" mentioned in your question.

"Very-Urgent" = "Please ignore my message". That's the meaning in forums.
Anyway, a crude way:
char ch[128];
CString cs = "YourName";
strcpy(ch, (LPSTR)(LPCTSTR)cs);
You can also use GetBuffer, ReleaseBuffer.

I'm gonna disagree with you here VuNic. The CString has an LPCTSTR operator, which means that casting to a TCHAR* is automatic. If you want to convert it explicitely to a char*, then it probably means you did something wrong with the code and you don't know how to use anycode properly.
Anyway, calling GetBuffer/ReleaseBuffer is NOT something I would suggest, because as I said the CString already has an LPCTSTR operator, so the GetBuffer call returns exactly the same.

Yes, try to understand what you are doing . For instance by reading this excellent article[^] (but I think Hamid already provided a link to the article).

lol that's why I called it a crude way. But it's not going to make any terrible impact there as he's coping the buffer. But a bad practice I agree.

Yes it is: if UNICODE is enabled, then you just copy a unicode string into a non-unicode string. That's why it is much better to understand what's going, otherwise you will end up with unexpected results.

When he said CString to char[] it looked apparent it's non-unicode. Otherwise he'd have used TCHARs. But as I said it's still a bad way.

No, because when you never heard about UNICODE (like me when I started) and if you are using the latest visual studio versions where UNICODE is enabled by default, then you are in trouble.
When I didn't understand anything about all that stuff, I was still using char* everywhere (instead of TCHAR*) and was forcing casts between everything. I can tell you that my code was a big mess 
VuNic wrote: Otherwise he'd have used TCHARs
TCHAR is the generic type, it is not specifically UNICODE. You should use TCHAR as often as possible...
Anyway, my whole point was: do not use GetBuffer/ReleaseBuffer and explicit casts, unless you exactly know what you are doing .

|

Yep that would be really a mess in particular if you had used char* specific library functions.

Agreed. . I feel lazy at times & use these crude ways but only when I'm sure nobody else handles the code.

Noone should suggest GetBuffer/ReleaseBuffer (unless Mark is nearby...) just because of LPCTSTR operator return value isn't the same.
