You first need to check that the string is a valid integer, so you should use TryParse[^].

Are you looking to delete both the data and the structure on the SQL server?
If so, I believe you want the "DROP TABLE" SQL command.

I'm learning MVC.
So far I have customized the default sample app.
One thing that leave me baffled is...
In the samples app there 2 web config!!
~/web.config
~/Views/web.config
WTF?
Why 2? Which one does what? What's the point?

First thing, you can have multiple config files at different levels. One in root folder and one in other branch folder is perfectly Ok. At times, it is needed for folder configuration.
Out here, Views config is to configure views. It is there to block direct access to the view aspx pages that are supposed to be served only through controllers.

So I have a program that was written in visual studio and goes through vb c# then to fortran to calculate values. I am trying to get this to run online and running into problems.
I first tried asp.net in vb where I created a new project and referenced the DLL's that were created by the original code, which only worked on the computer the original code was written on and would fail on my computer during the fortran transistion.
Stepping through the code did not solve anything either as when it cycled through the fortran code it would get to a certain part and fail. It gave me a chance to look at the disassembly because there was no actual error message and it had a file path in the problem area of the disassembly.
I have attached images of the problems I was getting during trying to solve this.
This error message appeared after running the asp.net program the first time before the browser popped up

This error message appears after I have entered all the values in the input form and they get submitted to the code.
http://i.imgur.com/yaau5At.jpg[^]
I am wondering if it is an pathing error based from the second picture as the actual asp.net program was in my C:\users folder but the source file is saying C:\Data(which was the file structure for the computer the original code was written on) when it shouldn't need to go to C:\Data if all of the code is complied into dlls that are added as references.
I am now trying to implement it into python but am not getting as far, so if someone could help me out with the asp.net problem or have another way that this can be put online that would be greatly appreciated and I can also supply more information if it is needed.

Some comments on the ASP.NET error:
- Don't use
Catch ex As Exception; only catch the exceptions you're able to handle. - Don't use
Throw New Exception(...); always use a more specific exception type.
For example: Throw New InvalidOperationException(...). - If you're catching an exception and throwing a new exception, always pass the original exception to the
innerException parameter of the new exception. This will preserve the information about the original exception, which will make it much easier to debug.
Throw New InvalidOperationException(..., ex)
At the moment, all we know is that something within or called by your setPressureTemperature method has thrown an exception; we have no way of knowing what that exception was. - Once you've updated the code to pass the inner exception through, run your code again and look in the application event log. The full details of the exception should be logged there.

I am building a website in which I need to show the price of items in different currencies depending on the country chosen by the user.The price has to be dynamically updated daily based on the exchange rate. How do I go about doing this in ASP.NET?

This suggests you to have a dropdown where user can select country and thus currency.
Based on the dropdown selection, get the latest data, convert anything that needs to be based on currency multiplier and then use the modified data as input for the page display.
Try out.

Hi,
Actually,I'm not using a dropdown list.The website is an international one in which there are different home pages for different countries.So,I want to show the images and prices of different watches on the website and the price should be updated dynamically depending on the exchange rate.So,how do I get the exchange rate values to do such a dynamic update?

Even then, there must be something that is driving the localization. Dropdown is just a way to know what country/currency. Whichever way you are chaning your homepage, based on the same paramter your data should be changed/driven.

I think you are looking to get the most recent exchange rate.
Check out: http://www.webservicex.net/ws/WSDetails.aspx?CATID=2&WSID=10[^]
You could write a small program that would invoke this webservice for the currencies you desire and store those rates in a lookup table which your drop-down list would be bound.
Good luck.

Not advisable as you will be blocking sever memory and can be very bad when multiple people connect.

Session timeout is set in Web.Config file. Default is 20 min. Change it to as per need there and will be used by IIS. You can also have FormsAuthentication timeout if you are using FormsAuthentication.
Following is sample change in Web.Config file:
<system.web>
<authentication mode="Forms">
<forms timeout="55"/>
</authentication>
<sessionState timeout="60" />
</system.web>

I have a variable that is declared in a user control. It is the value of a drop down list in the user control. When I try to use it in an If statement on an aspx page it says that the variable is not declared. Is there a way to declare the variable on the aspx page or make it recognize that it is declared on the user control page?
I'm calling the code at the top of the aspx page
<%@ Register src="pType.ascx" tagname="pType" tagprefix="uc2" %>
I'm using the if statement
<%If pt.SelectedValue = "1" Then%>
\\do things
<%End If%>
In the control pt is defined by
<asp:dropdownlist id="pt" runat="server">
Thank you!

Hi,
have you tried like this.
say you have used the user control like below in aspx page.
<uc2:pType ID="pType1" runat="server" />
so, in your code behind of the aspx page,
dim pt as DropDownList = CType(pType1.FindControl("pt"), DropDownList)
If Not pt IsNothing Then
If pt.SelectedValue = "1" Then
End If
End If
hope it helps

What do you want to do? You can always tie up the dropdown onchange (client side) or selectedchange (server) events to check the value and do some work.

I have a list of session ID
Session_Start
<pre lang="c#"> public static void Management_SessionUserDelete(string UserID)
{
System.Data.DataTable dt = (System.Data.DataTable)System.Web.HttpContext.Current.Cache["SesionList"];
for (int i = 0; i < dt.Rows.Count; i++)
{
if (UserID == dt.Rows[i]["UserID"].ToString())
{
System.Web.HttpContext.Current.Session.Remove(dt.Rows[i]["SessionID"].ToString());
dt.Rows[i].Delete();
break;
}
}
dt.AcceptChanges();
System.Web.HttpContext.Current.Cache["SesionList"] = dt;
}</pre>
Can be removed from the authentication code؟
