See here.

Had you used <pre> tags, and proper indentation, you could have quickly seen the error:

using namespace std;
 
int oo(int m);
 
int sum=0;
 
void main()
{
    int m;
    cin>>m;
 
    oo(m);
 
    cout<<sum;
};
 
int OO( int m)
{
    for(int j=2;j<=m;j++)
    { 
        if (m%j==0)
        { 
            sum=sum+j;
        };
        
        if (m==1)
        {
            return -1 ;
        };
 
    return OO(m/j);
};

Once you address the C1004 error, you'll still be presented with a LNK2001 error, however. And to top it all off, a stack overflow is imminent.

The "error" is that you did not use the debugger.

CString::Find ("html::") ?

CString::Find ("href=") ?

I don't know of any *nice* tools for it, but there may be!

Or you could write a nice class for it, and make an article?

I am writing a mouse hook program to trace the mouse movement and something confused me. I use WH_MOUSE to hook the mouse event in global wide, but some message like WM_MOUSEMOVE can not hooked when the mouse leave the window with a left/right button down, so I have add the SetCapture() function to my code when the GetCapture() return NULL, but it does not worked well, in some window like "MS word" or "Winamp" it go wrong.

I have also tried the WH_MOUSE_LL, it realy worked well. but it slowness the animation In window XP when turn on the visual effect "animation the window when Maxminze or Minmize", you will find the mouse move slowness when you click the mini/max box in the titlebar in any window with the mouse move quickly.

It totally confused me, some one can help me.

Thanks.

First question, why do you want to hook the mouse?

Second question - What makes you think you can capture the mouse and no other app
is going to capture the mouse itself?

That's a naughty thing for a mouse hook to do Smile | :)

Slowing the system down with your
hook is generally considered BAD as well.
