This is a simple problem, most likely, for most; but not me...
I am trying to enable "What's This" help in a context menu (right click
interface).
I have so far been able to properly code the OnHelpRequested function that
calls when the user clicks the little question mark and then a control on
the
form so that a tooltip pops up and displays useful information regarding the
object under question.
However it does not seem to be so easy to do this from a right click menu.
If it isn't System.EventArgs giving me a hard time its
System.Windows.Forms.HelpEventArgs telling me its incompatible.
EventArgs has no Draw or MousePos definitions. I have stressed every
possibility that comes to mind. It could be a simple line of code that I am
missing; or something along the lines of creating a few header files.
I've been plunking away at this for weeks, can anyone lend a hand?
I'll provide a few snipits of code so you can get an idea of what I'm doing.
Thanks =)

------------------------------------
private void InitializeComponent()
{
[.....]
//
// Form1

[.....]
//Here I handle the overflow for the helpbutton click with a
delegate
this.HelpRequested += new System.Windows.Forms.HelpEventHandler(
this.OnHelpRequested);
----------------------
/*
The code on the form is as follows
*/
// Handle the Help requested event when the questionmark button is clicked.
private void OnHelpRequested(object sender,
System.Windows.Forms.HelpEventArgs hlpevent)
{
if (Control.MouseButtons != 0)
// This will show the tooltip help for the "what's this?"
request
{
// Gets the control of the mouse position where the user
clicked
Control ctl = this.GetChildAtPoint(this.PointToClient(
hlpevent.MousePos));
// Reads the tooltip associated with the control
string toolTip = this.toolTip1.GetToolTip(ctl);
// Displays the tooltip, and ensures it doesn't try to
display a blank one
if (toolTip != "")
Help.ShowPopup(ctl, toolTip, hlpevent.MousePos);
return;
}
else
// If its blank it will bring up the F1 Help, which I
haven't incorporated yet
//ShowHelpTopicId((int)HelpTopicIds.IDH_DEFAULT);
// Set flag to show that the Help event as been handled, incase
I get errors
hlpevent.Handled = true;
}
/*
I'm trying to make this function do the same
*/
private void whatsThisToolStripMenuItem_Click(object sender, EventArgs e)
{
}
/*
Its initialized delegate looks like this
*/
this.whatsThisToolStripMenuItem.Click += new System.EventHandler(
this.whatsThisToolStripMenuItem_Click);
