    Read the MSDN page on it for information on nMaxPos:

    http://msdn.microsoft.com/en-us/libr...99(VS.85).aspx

    The default range for a standard scroll bar is 0 through 100. The default range for a scroll bar control is empty (both the nMinPos and nMaxPos parameter values are zero). The difference between the values specified by the nMinPos and nMaxPos parameters must not be greater than the value of MAXLONG.
    However, please note this:

    Note The SetScrollRange function is provided for backward compatibility. New applications should use the SetScrollInfo function.
    So, you should be using this: http://msdn.microsoft.com/en-us/libr...95(VS.85).aspx

    Noticed the 100 in most examples, but wasn't sure if it's standard... Thanks
