Hi there evrybody,
I am new to programming... I'm busy doing C# programming, well I'm still on the beginning but I'm getting there.
But anyway I need a solution to one problem that I have. Here is it:
Create a form with two list boxes. Add a number of items to one list box at design time using the Properties window. Create a button that, when clicked, removes the selected item in the first list and adds it to the second list.
You would probly say, that is peanuts... But for me, I'm new I don't know much yet. It's mind boggling.
Can anybody pleas help me with a solution to this.
Thank you,
Johan

A problem phrased like that just doesnt happen in the real world, which means this is homework. While nobody here has any problem with helping people out with their homework, you are unlikely to find somebody who will just give you the code.
So, give it a try yourself, and hit us back with any specific programming problems you encounter, remembering to include the code.

As the other poster said, we won't give you a solution, but we're glad to help you out. What part of the assignment do you not understand? Are you having problems creating the form in the .NET interface? Are you having problems with the initial population? Or are you having problems with the transfer from one list box to the other?
Again, ask a specific question and there will be a lot of people who will be glad to point you in the direction of an answer, or provide a small answer themselves, but we won't do your work for you.

hi
I am having strange problem in my class file.I am adding collection to support vector struct but it gives me these two warnings
C:\Visual Studio Projects\Cons12\EntryPoint.cs(24): 'Cons12.VectorClass.Vector' defines operator == or operator != but does not override Object.Equals(object o))
C:\Visual Studio Projects\Cons12\EntryPoint.cs(24): 'Cons12.VectorClass.Vector' defines operator == or operator != but does not override Object.GetHashCode()
I am unable to understand what it is and how it can be resolved
Can anyone explain me how and why it happens the above error
thanks in advance

Did you used the overwrite word in the definition of the new operator?

These warnings are telling you that because you have overriden the == and != operator there are 2 further methods inherited from Object that you should override.
Equals - returns true if the object passed into the obj parameter should be considered equal the current object
GetHashCode - returns an int used in hashing algorithms. Objects that return true from Equals should return the same HashCode from this method.
You can override these methods in your object by using the override keyword.

Are you sure that they are errors, not warnings?
The compiler says that you have created a class that will behave erratically. The Equals method should give the same result as the equality operator, so if you override one of them, you should override the other. If you compare the object to something, it will first look for a specific equality operator for the data type, and if none exists, it uses the Equals method. If you have overridden only the equality operator but not the Equals method, the comparison will work differently depending on what you compare it to.
The GetHashCode method is used among other things when you put an object in certain collections. If the GetHashCode methods isn't based on the same data as the equality operator, the object won't work correctly in the collection.

It must be a warning !
simply ignore it
or add Equals, GetHash function

I´ve made a desktop application in C# (.NET 1.1) and now I would like it to run in a local intranet. I know that I can change the .NET configuration on each client and give the application FULL_TRUST permission on the machine ... but isn´t there an easier way ??
Each assembly in the application is strong named, and I seem to remember that this should make it possible to have .NET prompt each user for FULL_TRUST permission when the application is initially launch. This would remove the need for changing the .NET configuration on each machine and make my life much easier 
Is this possible or is my memory playing me for a fool

hi.. in fom1 i have some controls ( for example datagrid1,textbox1,2,3 ...,button1,... )
and i want set properties of datagrid.forecolor (for example) from form2 ( form2 = setting window for example )
how to do that ?
|

The controls are not public so you can't set the properties from another form. You can either set the controls to public (not good) or code own properties or functions to control the properties of the controls (better).
Greetings,
Ingo

hi thanks for your reply but i tested this solution and don't gave result
i believe this is may but how ?
|
|
|
|

Is an error thrown? Perhaps you can quote this part of your code. It's hard to guess the mistake, when you don't know what was done?!

You don't have to ask the same question more than one time within an hour. Other wait some hours, a whole day or more before the question is answered. And they don't start you new thread every thirty minutes.

Well I started a test and tried:
System.Diagnostics.Process.Start("http://www.google.de/");
This should start your Browser with the Google Homepage.
