How To Make A Class Recognize That An Interface Found In A Separate File Exists
Mar 8, 2010
I've made an interface called ApprovalEvent in a separate file with the namespace myproject... I've also made a class called PurchaseOrder... it's also in the same namespace, just in a separate file. Whenever I try to make PurchaseOrder implement ApprovalEvent it always says that ApprovalEvent is undefined...
How can I make the class recognize that the interface exists but is in a different file?
Here's some code:

Since App_Code doenst exist as an ASP.NET Folder, I manually added App_Code as a regular folder, then within that I placed technologydescriptor.cs. Although it now has the appearance of an ASP.NET Folder.But for some reason my code doesnt recognize this class if its w/in the App_Code folder. This is picked up if it is not within that folder- why?Error: "The type or namespace name could not be found, are you missing a using directive or assembly reference"

Here is the scenario. I have several objects that use the same underlying interfaces IActivity and IOwned.
IActivity implements IOwned (another interface)

I am using some code I found that generates a random password. I am in the habit of putting code in a seperate file. The code was written in the same file and I'm trying to move it to a seperate file and get the following message. Also, below, I posted
the original code (code on same page as aspx) and what I did (code in seperate file).what adjustment needs to be made to make the seperate code file work?
Compiler Error Message: BC31143: Method 'Public Function GeneratePassword(length As Integer, numberOfNonAlphanumericCharacters As Integer) As String' does not have a ignature compatible with delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.

We have a WebForms Control which requires that the ID of another Control implementing ITextControl is provided.What exception should we throw if there is no control with that ID or a control is found but it's not implementing the interface?
[code]...
Should we split it into two cases and throw one exception if there is no control with that ID, and another one if said control does not implement ITextControl?If so,which exceptions should we use then?

I have a block of SQL statements that I like to use as a sort of function.
I was thinking that I could make a class and inherit all of the master function, then add the parts that I need for other sections of the program in a sub class.
The problem is, up to this point I've been programming ASP .Net through visual studio, and it's kind of just programming behind controls. I'm not sure where to put the class/function/method/interface, or whatever we call it.
Of course you probably know that visual studio creates a bunch of partial classes when you do an ASP. Net application... so.. to get access to a function like object, across classes.. use an Interface?

There is a SearchPage which has a properties ErrorMessage, SuccessMessage etc. This is basically a MVP pattern so for each page(view) there is IView that contains definitions for all the properties
I am using decoratoe pattern to set these peoperties dependingon the message type. There is another Interface IBaseMessage which has a method DisplayMessage() and a class BaseMessage which implements the interface. This class has a definition of the view
Interface IbaseMessage
{
DisplayMessage()
}
baseMessage:IbaseMessage
{
public Iview _view{get; set;}
DisplayMessage()
{
_view.Warning ="<message>"
_view.error="<message>"
}
Here, I am not able to set the message to the view properties. I am getting the error as "Object reference not set to an instance of the object"

I have created a user control which is inside a folder called Controls and the class is a partial class which inherits from Web.UI.UserControl. Now from my page which is one level up I just try to access the method inside the usercontrol and so trying to cast it as the type of user control. But I get build errors. It just cannot recognize that class. I get Type not defined error. But at times it has recognized the class. Dont know why it does that.

I am not sure how the user defined class objects are garbage collected. Do I need to implement IDisposable interface on every class and call the dispose() method on it to free the memory?

I have a hierarchy in my website project as below:
[CustomControl1 - folder]
- CustomControl1.ascx
- CustomControl1.css
- CustomControl1.js
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?

I'm wondering how I can go about accessing page controls from a separate class I've made. I've tried a few things I found using google, but no luck :(
What I'm trying to do is keep a function that is used often, in a global class.
The function then accesses a page literal and calls ScriptManager.RegisterStartupScript. I was hoping this is possible, so then this function wouldn't have to be copied to all of the pages.

I have a 2D array of doubles in my Default class on my Default.aspx.cs page, like so:
protected Double[,] time;
By the time the page loads, I have populated this array from a database. Now, I want to reference this array in another file (Diff.aspx.cs) to avoid visiting the database again. Also, the data is used in a read-only fashion.
