Setting text on tooltip from variable

Ok, I'm still missing something here.

I can very easily set the text property of the notify icon within design view but I don't believe this
will work for me.  How can I set variable information within the text string as well.  I tried to put the following
in to the "Text" location 

"State " + currentState

But when doing this I just end up with a ToolTip of "State " + currentState (in plain text form).  It is not reading
my variable information of currentState.

Thanks,
Bob

Ok,

I tried to add this code to the constructor of my main for and received multiple errors.

I have 2 variables I am working with.

string "status"
string "reason"

I have created a new variable called combinedStatus of type string

My goal is to do the following.

when the mouse pointer hovers over the notify icon (in the systray) for my main form application I would like the tooltip
to display the information (text) contained in the variable called combinedStatus

--where---

combinedStatus = "You are currently in " + status + " with a reason of " + reason;

Errors I am getting:

C:\Documents and Settings\rboursaw\My Documents\Visual Studio Projects\2004\ECSAgentDesktop\ECSAgentDesktop\AgentForm.cs(61): An object reference is required for the nonstatic field, method, or property 'ECSAgentDesktop.AgentForm.state

C:\Documents and Settings\rboursaw\My Documents\Visual Studio Projects\2004\ECSAgentDesktop\ECSAgentDesktop\AgentForm.cs(213): The best overloaded method match for 'System.Windows.Forms.ToolTip.SetToolTip(System.Windows.Forms.Control, string)' has some invalid arguments

Any thoughts?

Try

ToolTip t = new ToolTip();
t.SetToolTip(TheControl,"TextUWantToSet");
