Hello
I have a .NET CF project. In the project directory I put a simple xml file (users.xml) which has to be read by the device. When I debug the application on device emulator and try to load the file from code, the Exception is thrown (FileNotFoundException "Could not find file '\users.xml'.").
Is there a mechanism to automatically deploy also configuration files to a device emulator?

Inherited properties and MetadataType does not seem to work with client side validation in ASP.NET MVC 2.
The validation of our MetadataTypes work as expected on the server but for some reason it does not generate the appropriate client scripts for it. Client side validation kicks in as expected for properties with the DataAnnotations attributes set on the PersonView so I know that client side validation is active and that it works. Does anyone know if or how it can be fixed?
Here's what we have:
public abstract class PersonView
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
[Required] public string PhoneNumber { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string AddressZipCode { get; set; }
public string AddressCity { get; set; }
public string AddressCountry { get; set; }
}
[MetadataType(typeof(CustomerViewMetaData))]
public class CustomerView : PersonView {}
[MetadataType(typeof(GuestViewMetaData))]
public class GuestView : PersonView {}
public class GuestViewMetaData
{
[Required(ErrorMessage = "The guests firstname is required")] public string FirstName { get; set; }
[Required(ErrorMessage = "The guests lastname is required")] public string LastName { get; set; }
}
public class CustomerViewMetaData
{
[Required(ErrorMessage = "The customers firstname is required")] public string FirstName { get; set; }
[Required(ErrorMessage = "The customers lastname is required")] public string LastName { get; set; }
[Required(ErrorMessage = "The customers emails is required")] public string Email { get; set; }
}
As you can see, it's nothing fancy or strange in there... Can it be fixed? Is it a bug in ASP.NET MVC 2?

Hi,
I want to detect if a window form is open and if it is then I would like to bring it in front rather than opening it again.
I know I need a form collection for this but I want to know if there is a built in form collection that holds all the forms in VB.NET or I need to implement my own.
Thank you.
I'm implementing paging on an ASP.NET MVC view, and I want to call a method in the controller from the view.
Code in the view:
<a href="<%= Url.Action("Search",
new { page = NextPage(Request["exactPage"])).ToString()}) %>">
Controller method:
public string NextPage(string currentPage)
{
return (int.Parse(currentPage) + 1).ToString();
}
How can I call the NextPage method from the view?
thanks!
We are running an ASP.NET app on a web server with 4GB+ of memory in IIS 6. After reading many articles, it states that we need to set the "maximum memory used" for the Application Pool to 800mb to eliminate the "out of memory exceptions" that are happening for us. However, what should the "maximum virtual memory" in the Application Pool be set to? I can't find information as to what that should be set to.
We are developing a very complex eCommerce portal using asp.net c# and the client asked us to make the documentation very similar (look & feel) with ebay api documentation http://developer.ebay.com/DevZone/shopping/docs/CallRef/GetSingleItem.html
Do you have any idea what kind of tool they are using and if not do you know anything that can be configured to produce a similar result ?
Thank you in advance !

Is it possible to host 2 asp.net projects off one ip address? I don't have a domain name just an ip number. I'm running IIS7.
The first project runs and displays fine over the web by simply typing in the ip address into the browser but I'm having trouble accessing the second.
Currently both projects have virtual directories in IIS7.
Help is greatly appreciated.
Thx

I'm having a lot of problems with FormsAuthentication (http://stackoverflow.com/questions/2964342/problem-with-asp-net-authentication) and as as potential work around I'm thinking about storing the login in the Session?
Login:
Session["Auth.ClientId"] = clientId;
IsAuthenticated:
Session["Auth.ClientId"] != null;
Logout;
Session["Auth.ClientId"] == null;
I'm not really using most of the bells and whistles of FormsAuthentication anyway. Is this a bad idea?
I recently moved to Visual Studio 2010 and upgraded my website to work with .NET Framework 4. (From VS 2008 - Framework 3.5)
What are things I need to know to improve site speed, readability or memory use?
For example, I found out that when I use AJAX ScriptManager, one of it's new properties is EnableCDN which enables me to load AJAX .js files from Microsoft CDN.
