In the example below we will display the latest daily stock chart for a given company . A form will be displayed to the user allowing them to enter a valid stock symbol for a company . Typical symbols are MSFT for Microsoft and SUN for Sun.
The first part checks to see if there has been an entry on the form , if not the form is displayed again .
<%
If Request.Form("ticker") = "" Then
%>
<html><body>
<form action = <%= Request.ServerVariables("SCRIPT_NAME") %> method = post>
Enter your ticker symbol :<input type = text name = ticker size = 6><br>
<input type = submit value = "show chart">
</form>
</body></html>
<%
If a user does enter a ticker symbol then the appropriate chart is displayed using the code in the second section.
else
%>
<html>
<head>
</head>
<img border="0" src="http://ichart.yahoo.com/t?s=<%= Request.Form("ticker")%>">
</body>
</html>
<%
End If
