CImage's save

I save image using CImage class and fail if I mention the path selected from a CFileDialog object
That means I can straightly save the stream with a CImage variable as
m_img.Save(_T("image.png"));

but it seems unable to work with this path
m_img.Save(_T("C:\\Documents\\image.png"));


I have 2 buttons on my dialog, one to save the stream as specified in my first example, and another is to save as in the second. I press the first button to see a file created and press the second one to see nothing.
If I try to get comerror I will see 80004xxx (I forget what xxx is)


Any help please ?????????

Before executing the button press events I have codes to check the m_img's NULLable, I find it's not NULL before saving. I also see the path in debug view. :(
Help me please, or I am not finishing this exercise. I'd like to solve as many exercises as possible to make up for my mistakes. It's too late now I almost can't sit and wait for you anymore..

Hi,
Well it works when I use an absolute path.

Are you sure the "Documents" folder exists?

Of course, I choose to save it as an image file from a browse button invoking an instance of CFileDialog
