Declare a constructor for the frmToolBox that takes an instance of the main form
public FormToolBox(FormMain formMain) and then create an instance of the tool box form as follows
frmToolbox = new frmToolbox(this);

Thanks for replying however this isn't the problem, I've thought that myself. The problem is:
Stefan Troschtz wrote: frmToolbox = new frmToolbox(this);
This does NOT work as I experienced yesterday. I can't pass the MainForm around in the MainForm code using 'this' 
Problem not solved

I do not get your problem. What exactly do you mean by "does not work"? Where exactly are you creating the frmToolBox instance?

Hello,
Am I wrong, or are you trying to use "this" in the "static void Main"?
This will not work, you have to do it in the Mainforms cunstructor.
All the best,

You are right, I didn't initialize that object in the constructor
Now that I did, indeed it takes 'this' as a reference, however all of my other methods are souped up since now toolbox doesn't exist enymore as a class parameter.
--> The name 'toolbox' does not exist in the current context.
Stuck again. I'm just stupid I guess..
Sigh

Ok, good so far!

The "trick" is that you declare the variable outside the constructor and initialze inside.
private SomeClass mySomeClass;
public MainClass()
{
InitializeComponets();
mySomeClass = new SomeClass(this);
}
Hope it helps!
All the best,
Martin

I've added another constructor to my Toolbox which takes no parameter so now I have
Toolbox(Mainform mainform){ ... }
and
Toolbox(){}
however, this results in an infinite loop...

I've said too much. Appearantly it does work (I made an error)
thank you guys

Hello,
Glad it works now!
But why do you need this second constructor?
All the best,
Martin

I think, you need to show us some more code, cause otherwise otherwise there is too much guessing in helping you. What are you doing inside the constructors? Where exactly are creating the mainform and toolbox instances?
Finally, nevertheless a guess. Probably you're creating a new instance of the main form inside the tool box constructor. That is not necessary. Simply assign the instance passed in to the declared field.
class ToolBox
{
private MainForm mainForm;
public ToolBox(MainForm mainForm)
{
this.mainForm = mainForm;
..
}
}

Perhaps you need to do better at asking questions. If you're inside your mainform, and not inside a static function, this will work. There Application object also has a collection of open forms, which you can also iterate through and look for your mainform. But, when someone tells you how to do something,
motojojo wrote: This does NOT work
is useless. Tell us WHY it won't work, what the error is, and then we can perhaps tell you what's going on, without having to guess. Odds are high it's in a static function, and if you bothered to read the error message, you'd understand why it's not working.

You are asking about the cursor, but your concern is about scrolling behavior.
To add a background color to a cursor, you build the cursor. To use the cursor, it has to be installed on the target system and you have to set the cursor in some event and reset to the default cursor in some other event. Needless to say, because of the installation issue, your intended usage of the cursor is impractical.
As for the scrolling behavior, that's a design issue you handle through your control. Usually, you would select or focus the line so that it will be re-drawn in a focused state.

hi,
Thank you for u r reply.
If I scroll the cursor through using keyboard Up/Down key as the cursor moves Up/Down the current line of the cursor background should channge.
Thank You

Then you are not meaning the (usual) screen cursor, you are meaning the cursor which indicates focus of the current line. See the documentation for the control to find how to select/focus the current line.

hi,
May i know how to focus it.
Help me
Thank U

I don't even know what control you are using, so I can't help you more than I have. But you need to help yourself at this point, because this is a usual chore of programming. Look up your control in documentation, find its "members," and browse them. You should find a property or a method which will focus your line. If not, what you want to do is not supported.
(Surely it is.)

Hi guys ! I'm writing a win app that has two languages and i want to switch between languages. normally i press Alt + Shift to change the language, is there any way that i can do this automatically for example in an OnEnter event of a Text box !!! i tried somethin like sendkeys but didn't work for me !
Thanx
Mr.K

If you have a method that already does what you want (as you write), then simply call the method from your OnEnter handler.

Does anybody have a pattern handy for mapping design time help requests to name anchors in *real* online XHTML help? In other words, I assume I'd want to use an existing or custom attribute on properties, and somehow detect when help was requested for each property, then invoking a url to online help such as ourdomain/help/helpfile.html#PropertyName.
