Well - your code is OK - I've just tried it and it works even if you don't startup GDI+ properly. You do have to remember to blit the bitmap to the window DC to see anything, mind.
So - your code's (superficially) OK - maybe there's something about your setup that's not quite right?
What are the co-ordinates of your rectangle? What happens if you paint to dc rather than dcMem?

I have tried to test the parameters which were sent to FillRectangle function, I found that when they are big numbers(i.e, 200,000), the calling to FillRectangle will freeze.
But from my code, the value of CRect is got from API GetClientRect, does this function have some possibility to fail?

|

Can I suggest you set a breakpoint on FillRectangle and see what the client rect value is?

No，I didn't set breakpoint, I just create a CRect object with large paramaters:
CRect rect(0, 0, 200000, 200000);
//Disable this line
//GetClientRect(&rect);
|
|
|
|
|
No - get rid of those test parameters and try to find what the rectangle co-ordinates are when the call freezes when the rectangle is derived from the client rect.

I see, thanks for your mention

Hi there. The reason is clear. It's because that I called the GDI+ APIs in another thread, and GDI+ doesn't support multi-thread calling

大家好!我在处理从虚拟打印出来的EMF文件时，如果是打印的word。（打印其他文件没问题）在我旋转EMF文件时，图片会消失，图片上如果有表格的话，表格不会消失，文字绝对消失!!!!我旋转是用Matrix来实现的
这到底时什么原因啊！高手来说说，谢谢
================================================================
sorry ! my english is poor! 
virtual Printer print the EMF file ,if this file print from the word ,when i rotating the emf file ,the pictrue will disappear!
my code 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);
........
Why is it part of the disappearance when i rotating it, I do not know

Does it your qeustion?
Hello everyone! Treatment at my print out from the virtual EMF file, if it is to print the word. (No problem printing other documents) in my rotating EMF file, the picture will disappear, pictures on the table if there is, then, the form will not disappear, the disappearance of language is absolutely!!!! My rotation Matrix are used to achieve the
This is why when in the end ah! Master for that thank you

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>].

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
