Hey. I'm pretty new to ASP.NET and coding it in VB. I'm working on some tutorials on how to view and edit data from a SQL Data Source. I'm using the GridView feature, but I'm getting some errors. The major one, is that it requires me to declare a scalar variable, while the code in the book has none, and after trying to fix it, I'm getting to new errors while compiling, so the web page wont even load. I've been searching for a fix, but I don't understand what I've been finding. I'm including the code I have, and the two compiling errors I'm getting. Thanks for the help.

Here's the compiling errors:
Error 1 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. F:\WebMatrix\03B_fanbiopretty\web.config 86

The errors are both related to IIS configuration you need configure the application virtual directories as applications:


If you are using shared hosting you will need to ask the hosting company to configure it for you, or some hosting companies allow you to do it yourself via their control panel.


Your Subject is Misleading.

How did you deploy your Application. Please Explain step by Step , because if you have missed one simple step it will give you errors.

I dont use Wizards to do my database work, i can see that you have used a sqldatasource Control and really you dont have control over what is generated by the control. if you get an error that says you must declare scalar variable , you must know that one of the Variables in the Sql like @fName, am not sure how it works because i dont use it.

Hope i helped
