    Displaying an array value as text in windows

    Hi all,
    I'm having a bit of trouble checking that my program is working properly. I have defined a list of objects in an object array called "LineArray". One of the data members of these objects is an array to hold sets of random numbers called "m_XYCoOrds". What I want to do is to check that each object has different numbers in their own arrays.

    In the view.cpp file the OnDraw function looks like this:

    void CLinesView::OnDraw(CDC* pDC)
    {
    CLinesDoc* pDoc = GetDocument();
    ASSERT_VALID(pDoc);
    // TODO: add draw code for native data here


    pDC->TextOut(60,60,pDoc->LineArray[1].m_XYCoOrds[0][1]);
    pDC->TextOut(60,80,pDoc->LineArray[1].m_XYCoOrds[0][2]);


    }

    All that it ever gives me is the value I(1?) I do know that the co-ordinates are different because it can draw a line quite nicely. I think that i'm probably just using the wrong function to display the text. Any help would be greatly appreciated.
    Cheers
    Dylan

    You are using TextOut() incorrectly (unless m_XYCoOrds is a matrix of char*'s or CString's).

    You need ot convert m_XYCoOrds[0][1] and [2] into a C-string or CString to pass into TextOut().
