can't view web controls in my browser

[daves1]

Hi,

 

I am taking a Visual Basic.Net class and we have to build a webform. I can build the form in Visual Studio and I can see the web controls, but as soon as I try to view it in a browser, I can't see the web controls. I can only see the text, but no buttons or text boxes. The file has an aspx extension. Any ideas??

 

I am running Windows 2000 Professional as my OS. I installed IIS first and then installed Visual Studio. I have an inetpub folder and a wwwroot folder that is shared.

 

Thanks for your help!!!

Are you doing any coding, or chaning any of the control parameters?

I say that because if a control, such as a datagrid, is not correctly populated, it can just come up as blank, without an error (because syntactically there is no error) and stop the rest of the page from loading.

 

I started a new .net project c# web application on my local mahcine, then on the default web page dragged a button, calendar view and text box onto the page. Ran it and it worked... If you do these steps does it work for you?

The idea here is rather than the application being at fault, perhaps there's something dodgy in your configuration.

here is the code, it is right out of the book, and i still cannot view it with my web browser.

 

 

I get this error.

 

Server Error in '/' Application.

did you just load the code off a CD and onto the hard drive through explorer? If so, you'll need to make sure it's added as a virtual directory to IIS.

 

Perhaps the best way to do this is to create a new Visual Basic Web Application with the name, Ch09WebHello.

 

From here, goto the project menu, and select "Add existing item".

 

find your files from the project you want to add, and select them all, and select add.

 

final step, to make sure your default file is the project default, right click on the file you want to be your "index" file, i.e. initial file to load when the directory is pointed at, and select "Set as Start File".

 

Now goto Debug -> Start and see if it correctly compiles and loads up your program in the web browser.

 

Good luck!

i copy the entire folder to the inetpub/wwwroot

 

and then i execute the WebForm1.aspx file

 

when i do that, i just can see the hello world text, but not the button

[dunesand]

you can't do that because it's not setup in IIS properly... follow the steps i suggested and try again.

[daves1]

wow you are a genius. you are the only person who could figure this out. i have asked about 10 people about this, even the professor. it works great now. thank you so much.

[dunesand]

genius is pushing it... ;)

 

professor hey, he's probably as new to .Net as you by the sounds of it. I'm sure he'd whoop me in complexity theory. ;)
