Question

ASP - Web Matrix Server - Port 80 error: Appplication not found when clicking on "Open in Web Browser".

Asked by: Ainodecam

Hello all,

I'm new to ASP.Net and am using Web Matrix (as I only have Win XP Home Edition) and I get the error below when I right click on the Web Matrix icon to "Open in Web Browser".

I also noted that URL links don't work when I click on them from Outlook Express - nothing happens. This seems like a new phenomenon and maybe linked to my use of Mozilla and that browser having an exception error when I installed some other software like VS.Net 2003 or something like that.

I believe if I can get the IEXP to work from Outlook Express and remove Mozilla, my problem may be solved. IOW I need to make IEXP the default browser.

Any help here would greatly appreciated.

Thanks,
Chris.

Hello,
First of all, I need to check if you are clicking the .aspx file created via WebMatrix, or the WebMatrix icon itself. Also, whether you're clicking it in WebMatrix or in Windows.

If you're doing what I think your trying, you're clicking on the ASP.NET page (.aspx) you created via WebMatrix, in Windows, and trying to open it directly in Internet Explorer (or your equivalent web browser). This cannot be done without the page running in WebMatrix, because ASP.NET pages need to be 'hosted' on a web server to be run. WebMatrix comes with a built-in instance of a web server (hence the default Port 80), this is what runs when you click 'Start' when debugging.
To test if this is the case, open your page in WebMatrix and click Start. This will open up the page, using the built in web server. Now close the web browser that opens up, but don't stop the server (it usually sits in the System Tray, looking like a world with a ring around it). Open a new instance of your web browser and type in http://localhost:8080/MyPage.aspx replacing 'MyPage' with the name of the page you created. It should run with full functionality and no errors - unless you have bugs :D

For testing, WebMatrix is a great little application. Eventually, if you are creating sites you want to have visible via the outside world, you'll either need to use your computer as a web server (hence leaving WebMatrix running) or get your site 'hosted' by an ASP.NET hosting company who will do it for you.

As for your Outlook and link problems, i've not come across them but it sounds to me as if you are trying to do what I have detailed above - open the web pages directly without having them running on a server-instance.

Hope this helps, let me know if you need anything else.
mcg

Hi, thanks for the input, the problem was actually solved when I made IEXP my default browser. I just wanted to see if there was something else I needed to do.

Chris.

Not a problem - hope I gave you some insight into ASP.NET and web matrix! Good to hear your problem is solved
