HitTest returns System.NullReferenceException ? - SyntaxEditor for Windows Forms Forum

Hi,

I'm having a problem using the HitTest method.
I call it in the mouseMove method and everything works fine except if the mouse cursor is under the last line of code


protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs x_e)
{
    SyntaxEditorHitTestResult l_htr = HitTest(x_e.Location);
    if (l_htr.DisplayLineIndex >= 0)
    {
        ...

In that case :
* l_htr IS NOT null
* l_htr.DisplayLineIndex = System.NullReferenceException
(like other methods...)

I don't understand what's happening and I don't know how to test it !!!
(to avoid a try..catch)

Any idea ?

Thanks for your help

Stéphane

Hi,

Please make a simple project that shows it happening and email it over. We're not seeing it occur here. Thanks!
