...then why did you ask it in the C# forum?
There is a Visual Studio forum on this site. It would be more appropriate to ask your question there.

i need to set one image to tree view nodes and another image to inner sub-nodes

Define the images that your TreeView control uses by setting its ImageList property.
Set which image in the ImageList each node uses by setting the ImageIndex or ImageKey properties on each TreeNode object.
Read the documentation[^] for more information.

Hai everyone,
I am using the following code in my application which is giving an error.please help me .
objMenu.objForm = this;
this.Menu = objMenu.LoadDynamicMenu();
Error 1 Cannot implicitly convert type 'object' to 'System.Windows.Forms.MainMenu'. An explicit conversion exists (are you missing a cast?)
santosh.

seems that LoadDynamicMenu method returns am object.
so you need to cast it like:
this.Menu = (System.Windows.Forms.MainMenu)objMenu.LoadDynamicMenu();

Hello.
I have some trouble with List<>. I'll give you a short example, and you'll understand, what I need.
We have a console app.
Let's do some class:
class Class4List
{
public int var;
}
Now let's do a class, that uses a List<> of already created class:
class Class4Method
{
public void changeVar(List<class4list> c4l)
{
c4l[0].var = 1;
}
}
Main:
static void Main(string[] args)
{
List<class4list> test = new List<class4list>(); //create List of our classes
Class4List qwer = new Class4List(); //create a variable with our class type
qwer.var = 25; //give some value to a class member
test.Add(qwer); //add a variable to List
Class4Method tst = new Class4Method();
tst.changeVar(new List<class4list>(test)); //calling method of a class, that uses List<class4list>
}
But after calling a method, value of test[0].var and qwer.var will be "1"! But I don't need it. I want to change value of a variable only inside of method changeVar, and outside of this method it should still be "25".
How to do this?

Hi!
You're adding a reference to qwer to the List, so if you access this instance in the method you can modify its properties.
If you want a copy of qwer in the list, you should take a look at IClonable.

mav

I have your project ready to go. Contact me off the board for ways to pay the $10,000 consulting fee for writing this for you.
Or, you can do your own project ( is it your job, homework or a rentacoder job gone bad ? ), and then we'd be happy to help when you're stuck.

I am using a keyboard hook to stop most if not all the keys on the keyboard but i am getting this message:
CallbackOnCollectedDelegate was detected
Message: A callback was made on a garbage collected delegate of type 'Client!KeyboardHook+HookHandlerDelegate::Invoke'. This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called.
any ideas how to solve it?

Error messages are so informative these days, that it almost gets too easy.
You have the solution handed to you in the error message already:
"When passing delegates to unmanaged code, they must be kept alive by the managed application until it is guaranteed that they will never be called."
You have thrown away your reference to the delegate. Don't do that.
Experience is the sum of all the mistakes you have done.
