And I want money Big Grin | :-D

Anyway here's one way to do it:

1)Check if number is between 4000 and 8000

2) If so then check if it contains a "2". Something like this:

string nr = yourNumbert.ToString();

if(nr.Contains("2")){//do stuff

else{//complain about it

Good Morning,

When my application opens, it checks a version number from an online database to determine if it is using the most current version available. If not, I need it to be able to download the most current version from an online server and then install the application update automatically. I know we see examples of this every day, such as security updates in Windows or online checks for anti-virus programs. The check and automatically close if not installed are already working fine and return a Boolean. How do I force and install the download?

Thank You, Pat

Thank for your answer. I have marked it as correct for this issue. I was able to use it to get the string of code that I needed to resolve the download problem. Now, I need to be able to find a way to automatically install the download. Best Regards, Pat

User Controls and Class References

Hi all,
I have a NOOB question, when developing a custom user control how can you reference other classes or use a partial class? For some reason when I try to reference another class it can not find it. I tried using the same namespace in the separate class file and tried putting it in the bin directory without any luck. Thanks for the Help!

If the class is in another assembly you must remember to add a reference before it will be available.

Perhaps if you showed a bit of the code we could evaluate it. And don't forget to format the code using the pre tags.

I know the language. I've read a book. - _Madmatt

Thanks Mark, I was hoping it was something simple, sometimes the easiest things give you the most problems, here is a layout of my code....

myControls.ascx.cs:

namespace myControls
{
   public partial class MyUserControl : System.Web.UI.UserControl
   {
      public MyEnum myEnum; //******* Can not find enum *********

      protected void Page_Load(object sender, EventArgs e)
      {
        (.......)
      } 
   }
}

myControls.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="myControls.ascx.cs" Inherits="myControls.MyUserControl" %>
<div>

</div>

myControls.Support.cs

namespace myControls
{
   public enum MyEnum
   {
      Day,
      Week,
      Month,      
   }
}

Thanks again,
Andy

You need to include the namespace of that class in your project (if it is under a different namespace).

For e.g.

using System;<br />
using System.input;<br />
using myNamespace;

OR

alternately you could just try

new myNamespace.myClass().

Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

Abhinav,
I tried referencing the namespace but the main problem is the User Control can not find the separate class file. Everything works right when I include the Enum in the same file but when I try to use it it gives me errors that it can not find the assembly or reference.

Thanks
Andy

I saw your code (pasted above).
See a note here[^].

"The partial modifier is not available on delegate or enumeration declarations."

I don't fully understand your query - but are you just missing a project reference? As in solution exporer, project, references -> add reference?

Regards,
Rob Philpott.

Andy Braham10-Feb-10 3:07

Rob,
All of these files are in the same Project I have a UserControl and a class in a separate file but the UserControl can not find the class. I tried putting all of these in the same namespace and tried to use the namespace (using myNamespace.UserControl) without any luck. I'm sure it is a simple fix but I am new to C#. It's not as easy as including a C/C++ header file.

So (for my clarity) - you have a single project file which consists of various source files. Your custom control comprises just another set of source files in this project? What do you mean 'in a seperate file'?

I'm afraid I'm completely lost, but if it is just a namespace issue, get Visual Studio to resolve the namespace by doing a context menu on the type where the error arises and doing 'resolve namespace' (or something like that).

Regards,
Rob Philpott.

Rob,
Sorry for not being very clear....

In my project I have:

myUserControl.ascx
|->myUserControl.ascx.cs

myUserControlSupport.cs

myUserControlSupport.cs Contians Enum that I want to use in myUserControl but myUserControl does not see it and I am lost on how to reference it. I have the same namespace and a partial class defined but it still does not see it.

Thanks for the Help!
