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.

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! Sigh | :sigh:

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" ?

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
