Is there a max value for treeNode.StateImageIndex?

I have a stateImageList with 21 images. Any image above the 15th e.g. treeNode.StateImageIndex = 15, generates an ArgumentOutOfRangeException with message:

InvalidArgument=Value of '15' is not valid for 'StateImageIndex'

A max value isn't documented as far as I see. What am I missing?

Thanks

I see this behavior is documented for 3.0 but not in 2.0.

http://msdn2.microsoft.com/en-us/library/system.windows.forms.treenode.stateimageindex.aspx[^]

ArgumentOutOfRangeException - The specified index is less than -1 or greater than 14.

Fair enough.

I have an application that I want to start as soon as the user enters Windows. How can I configure this from the installation? Could anyone give me a link or some advice? Smile | :)

Make it a service. Get it put into the special Startup folder. Take your pick.

There are a lot of ways.

1) Windows Service (works even if no one is logged on)
2) Startup Folder of Users/All Users

Detecting Key Presses

Using the KeyDown event, i can see if a key has been pressed while the form is in focus, but how do i check what key was pressed?

Thanks in advance Smile | :)

In general, events provide the information you need. That is what makes them useful.

Have you noticed the two arguments your KeyDown handler is getting ?
There even is some documentation explaining KeyEventArgs if you would care to read it.

Smile | :)

In the end i figured out i could do this...

if (e.KeyCode == Keys.K)<br />
            { MessageBox.Show("Key was k"); }

Is that a poor way of doing it?

Also, perhaps you could explain the mystery e, ive used it in GDI+ too, but dont know what it is Smile | :)

You're welcome.

You may want to right-click on something and select "Go to definition", chances are
Visual Studio helps you in understanding what it is then (it does not work all the time).

Posting the same question multiple times in a couple of days isn't likely to make anybody want to answer your questions any faster; in fact it is likely to do the opposite.

You have to realise that the boards are populated by volunteers who give their time and experience freely. As a result, they will answer questions as and when they can. It is considered rude to pester the boards like this.

BUT If the time is important for you , you shouldn't waste your time by answering like this! Mad | :mad:

You answered like this because it seems you have no idea about the subject. so...

For developers:
Yes i know this question need a bit more time to answer , but i really need it!
and i tried many ways but i don't get any desired results.

Thanks just for any help.

Way Too Harsh. I would recommend that you first read the forum guidelines in being polite to people helping you.

Not the best way to get help, and certainly not when it was aimed at the person you you aimed it at. Check his profile / his message count / his help in this and other forums.

Good luck in the future 611. I for one won't even read your posts from now on. You might need to change that to Developer911 as you're gonna need all the help you can get - but not from me.
