::SetPixelV help please

Hi
Why when i use this code is my bitmap the right size but im trying to set just one pixel a certain color
but with this code the whole line gets turned into that colour
always my y co ordinate ??

Any ideas ?

say the RGB values are 128,128,128 instead of just getting a color dot at position x,y
i get a colored line at position x but all the way down line y ??

Code:

        CPen Pen1;
        LOGPEN lp;
        lp.lopnStyle = PS_SOLID;
        lp.lopnWidth.x = 0;
        lp.lopnColor = RGB(0,0,0);
        Pen1.CreatePenIndirect(&lp);

        // Create a brush
        CBrush brush1;
        brush1.CreateSolidBrush(RGB(0,0,0));

        CBrush* pOldBrush = m_pDCNew->SelectObject(&brush1);
        CPen* pOldPen = m_pDCNew->SelectObject(&Pen1);

        // declare a AFPDibSection
        AFPDibSection dib(nWidthInPixels, nHeightInPixels);

        // call the Rectangle function and draw a rectangle for the size of the bitmap in the AFPDibSection
        ::Rectangle(dib.getDC(), 0, 0, nWidthInPixels, nHeightInPixels);

        int x = 0, y = 0;

        // The amount of bits allowed in the line is as long as the width of the bitmap
        int bits_per_line = nWidthInPixels;


//******************** End *************************************************//

                for (int n = 0; n < strRawData.GetLength(); n += bits_per_line)        // loop through all the data
                {
                        for (int j = 0; j <= bits_per_line; j++) // loop through and get values from array
                        {
                                CString strRDRed, strRDGreen, strRDBlue;
                                int nrdRed, nrdGreen, nrdBlue;

                                // break up rawdata string into 2 chars
                                CString strTwoChars = strRawData.Mid(nStartingPosition,nTwoChars);
                                int nValue = HexToDec(strTwoChars);
                                CString strRGBColor = colorTable.GetAt(nValue);

                                // pull out colors
                                strRDRed  = strRGBColor.Mid(0,3);
                                strRDGreen = strRGBColor.Mid(3,3);
                                strRDBlue  = strRGBColor.Mid(6,3);

                                nrdRed  = _ttoi(strRDRed);
                                nrdGreen = _ttoi(strRDGreen);
                                nrdBlue  = _ttoi(strRDBlue);

                                COLORREF clr = RGB(nrdRed, nrdGreen, nrdBlue);

                                // need to set pixel color
                                ::SetPixelV(dib.getDC(), x, y , clr);

                                nStartingPosition += nTwoChars;

                                x++;
                        }
                        nStartingPosition = 0;
                        x = 0;
                        y++;
                }

Use the debugger to step through your code and check the values of strTwoChars and strRGBColor in the debugger.
