Community,

I am very new to using C# and to programming, period.

I am using visual studio's windows application. I am trying to have the application open up displaying two links. When each link is clicked, I would like for them to open up their own respective windows, whether they be window apps like the forms, or IE windows. I was trying to use the LinkLabels to do this. any help is appreciated.

Thanks,

Noob

Ok, your going to want to add this statement near the top (with the other using statments)

using System.Diagnost ics;

now in your link Labels on click event you want to add something like this

Process pIE = new Process();

pIE.StartInfo.F ileName = "http://TheLink.html";
pIE.StartInfo.U seShellExecute = true;

pIE.Start();

And that should do it

Heh, I just realized my variable name was pie, delicious pie :p

Have fun,

Thank you very much. The code worked great, but that works for external sites. Now the problem that i'm encoutering is that i've composed two HTML pages that use a combination of both HTML and Javascript. These pages are saved as .html files on my computer, and I moved them into the folder with the .cs file that I made in Visual Studio hoping that it'd find these .html files and open them. How do I get the code provided to open up these files that i've made?

NEVERMIND!!!

That is no longer my problem. I remembered that all I have to do is simulate a certain scenario, so that is not an issue anymore. I'm sure i'll have another issue very shortly. :-D

OK. The problem that I am having now is that when I click on both links, they are refreshing in the SAME window. I need the links to open up their own individual windows. I renamed the second process to pIE2 along with the two .startinfo statements and the one .start statement, but that's not making it open into a new window. any suggestions??

Hmm, doesn't happen in Internet explorer 7, it will open in a new tab.

Can I see the exact code your using?

But it could be that IE recognizes that it is already open and just changes sites instead, in which case, you might have to actually automate IE

yeah, that should have done it.

I don't have the old version of IE anymore so I can't reproduce it.

Looks like you're stuck with automation.

Or, if you know for sure where IE is, you can do something like this

pIE.FileName = @"""C:\Progr am Files\Internet Explorer\iexplo re.exe""";
pIE.Arguments = "-new www.google.com" ;
pIE.Start();

but if you are running it on more then one computer, and IE is in a different place (unlikely I'll grant) then it will break.
