Ok I know nothing about .Net dev but shouldn't it be something like:

label.location = system.drawing.point(W,L);

There are fundamental issues with this approach, to start with. If you move a label about, you don't really get a marquee, and you end up with a bunch of code you need to write every time you want to move text.

Hello Nikesh,

I is giving the following error:

cannot modify the return value of 'System.windows.forms.control.location' because it is not a variable

This code is an utter disaster

1 - it plain won't work
2 - no-one has a resolution that big, if it did work, the text would soon disappear
3 - it tries to move it in both the x and the y, a marquee moves only in the x

I'm afraid that your being unable to work out at least some of these things, and to work out how to modify the code so it at least compiles, is a firm indication that you're probably not quite ready to try and do this. I assume this is your first class assignment, I recommend just doing the parts that were assigned to you, and not worrying about anything fancy until you've learned some basics.

Yes, the new code you posted will probably work, although it's definately not how I would have done it, I'd do it the way it's probably done in the article that's been linked to, creating a control where the text scrolls across the area of the control, rather than having to write code for each string, to move a label control the right amount. Doing it in a control also allows for text to disappear to the left, and appear to the right. However, yes, I did see the code you posted, and so long as he works out to add a timer as well, it looks like it should scroll the text just fine.

You're new in C#, and you're writing a stock application ? I assume this is for a class.

The advice you've been given is vaguely on the right track. You should create a label control which draws itself in the marquee fashion. It can draw it's text using an offset, or just shuffle the string it shows ( move a letter at a time ). You set the positions within a timer, so you have a chance to see each one, and you need to call Invalidate() each time, if you draw it yourself.

The code you were given isn't going to do anything useful, but it has got a rough idea right, that you need to change the location of text so it will move

This will works it is tested
Try this.

<br />
private void timer1_Tick(object sender, EventArgs e)<br />
        {           <br />
            label1.Left = label1.Left + 20;<br />
            if (label1.Left >= 500)<br />
            {<br />
                label1.Left = label1.Left;<br />
            }<br />
        }<br />

timer must be enabled true

<br />
private void Form1_Load(object sender, EventArgs e)<br />
        {<br />
            timer1.Enabled = true;<br />
        }<br />

try this

Seriously, if you don't know how to do it, don't try to tell someone else how to do it. Changing the number won't make it repeat itself, you need all sorts of code that belongs IN the control to do that. Not a whole lot, but enough to make it messy if he has to do it manually.

I recommend you both look at the article that has been linked to, if you want to know how this is done.

Look, either read my advice and try to write something ( although I doubt you can at this stage ), forget it and focus on your homework, or download the control you've been given a link to. The advice you're choosing to pursue, while ignoring everyone else who is trying to help you, is really quite bad. If you're trying to add something cool to your homework, this is not the way to do it.

Again, the issue you have here is twofold

1 - you're getting help that *kind of* works, and ignoring my replies on the basis that I'm trying to get you to write some actual code for your assignment, instead of just getting it off the web. You don't learn anything this way.

2 - the fact that in using this code, you can't work out what it's doing, is a sure sign that you should not be using it, but instead focusing on your class, and on learning C# for yourself, instead of relying on others to provide you with code

There is nothing wrong with asking people for help, and nothing wrong with people giving you code. But, before you use it, you should use google to help you to understand it, so you could reproduce it yourself in future. That's what learning is.

In any case, someone else has given a link to a control you can use. I didn't look because, well, if you're doing homework, you should focus on learning, not on using other peoples code. And, in any case, you only had to type marquee into the search box on the site to find it for yourself.

API & DLL

what is the difference between API & DLL

MS Office API and MS Office Dll both are same ot not?

Re: API & DLL

Quoting Wikipedias definition for each term:

API[^]:
"An application programming interface (API) is a source code interface that a computer application, operating system or library provides to support requests for services to be made of it by a computer program."

DLL[^]:
"Dynamic-link library (also written without the hyphen), or DLL, is Microsoft's implementation of the shared library concept in the Microsoft Windows and OS/2 operating systems."

Hence, a DLL is one way to expose an API or parts of an API to the programmer. Another way to expose an API is through a Web Service[^].

So, to recap, the MS Office API is the specification of what functionality you as a programmer can use to interact with MS Office, while the MS Office DLL (DLLs actually, there are lots) is the binary code executed by the computer through you program if you use the API.
