Why does Internet Explorer ask to download a file when I try to view my aspx page?

This is because IIS does not recognize aspx pages yet. To fix this:
Right click on My Computer and select Manage.
Right click on Default Web Site and select properties.
Services and Applications -> Internet Information Services -> Default Web Site
Click on the Home Directory Tab
Click the Configuration button.
Click on Add.
Browse and find the file called xspisapi.dll. It should be at C:\WINNT\Microsoft .NET\Framework\v1.0.2204\xspisapi.dll . Make sure you are looking for dll files and not exe files or you won't find it.
Type aspx in the extension field and click Ok
Ok everything and you should be all set! Happy coding.

How do I create index.html in my root folder using Visual Studio?

If you followed the instructions above, you project will be in a folder under the root directory but won't the root directory itself. So in short you can't really do it in Visual Studio. However, you can easily make an index.html in notepad or any other text editor and create a link to a index page in your project directory.

Why aren't my files in my project? Did I lose them?

If you created a file outside of Visual Studio, you will need to add the file to your project in VS so that it can be built and used (applies only to aspx & C# files).

Where is my error log?

You can find your log file here: c:\winnt\system\logfiles\w3svc\date.txt

How do I get the current date and time?

.NET has a DateTime object. To see how it is used, check out the .NET reference documentation that can be found from your start menu.

How do I pass form data between pages?

There are quite a number of ways to do this and depending on the task at hand, you would probably want to use a different method. If you are thinking of passing form data to another page for Ex 3 it's actually not necessary, you can place it all in one page.
QueryString - Put it in the URL

In the button onclick event, you can Response.Redirect to another page placing the variables in the URL.

e.g.
String strURL = String.Concat("results.aspx?name=", txtName.Text, "&age=", txtAge.Text);
Response.Redirect(strURL);

Then on your results.aspx page you can call Request.Params["name"] to get the name and Request.Params["age"] to get the parameters.

Session - Save it a for awhile

In the button onclick event, you can save all your variables into the Session and then call Response.Redirect to another page that extracts the values from the Session again.

e.g.
Session["name"] = txtName.Text;
Session["age"] = txtAge.Text;
Response.Redirect("results.aspx");

Then on your results.aspx page you can create variables to retreive the value of the Session variables like:
String strName = Session["name"].ToString();
String strAge = Session["age"].ToString();

Server.Execute - Fake a page change

You can see an example of this at testform.aspx.
The second page testresult.aspx then calls Request.Params["txtName"] to recover the value.

How do I screen scrape?

For Ex 4 you will need to rip stuff off some other pages.

HttpWebRequest hwr = (HttpWebRequest) WebRequestFactory.Create(strUrl);
StreamReader strm = new StreamReader(hwr.GetResponse().GetResponseStream());

You can then parse the stream using a Regular Expression.
