For several days now I've been messing around with Ajax calls using different combinations of javascript, ASP controls, and regular controls. I've gotten a bit of understanding about what's going on, but using ASP controls still hides too much of the machinery, and I want to have a deeper understanding. With that aim, can anyone tell me why the following setup doesn't quite work?I have a file "Testy.aspx" with the following:[code].....
So, I hoped to make my .aspx file do double-duty both as the regular-page request handler as well as the Ajax request handler. However, when I click the button ("baroo") to generate the Ajax request, the result that ends up written back to the "testytext" div is the raw html for the entire page, as if under normal request conditions. Clearly, my attempt to override the page request by making the code-behind implement IHttpHandler and supplying an "Overrides Sub ProcessRequest" method is not working. The server is still treating the Ajax request as a normal request, and in fact my own "ProcessRequest" method is never even called.Is it possible to build a page/handler like this? How can I intercept the incoming request from the client and respond accordingly?This is how Ajax works, right? So it must be possible.Again, I'm deliberately doing this as an excercise to avoid the use of "magic" ASP controls like UpdatePanels,
I have created a WebBrowser and I want to catch the page that says "This program cannot display the webpage " instead of loading that page I want to display my own html code for that error. And also to catch error when loading an html page from a disk which is not present at all. (file not found)

My current problem, as stated in the title, is that I am trying to create a series of buttons from a custom class within app_code and place them on a master page. The whole reason for this is I do not want to have to copy and paste event handlers on the content pages.
However, upon the click of these buttons I need for a method on the content page to be called and update html within a div of the content page.Is there any way to accomplish updating the div of the content page from an event handler in the custom class? Remember, the method that updates the div exists on the content page.
I am trying to learn Visual Basic and am working through a text book that my son used for a class. Each time I create an event handler by double clicking on the design page, the code that automatically populates is almost identical to the code in the book, except the byval portion is omitted from the code.[code]
View 2 RepliesI have a windows application that has a tab control with 5 different tabs. Each of these tabs has a datagrid view that is populated with data on form load with data from SQL Server. I have an event handler for the datagrids for CellValueChanged that appends an asterisk, "*" to the tab, when a change is made, this is meant to mimic the same behavior in VS or SSMS. The issue that I have just realized is that on page load as the datagrids are populated this event handler is raised thousand of times. I have included an If Then statement to exit the sub if it occurs during page load, but am concerned about the performance implications, if any. Is there a better way to handle such functionality? Possibly a way to ignore the event handler on form load? If not is there a negative impact leaving this functionality in?

We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.
Consider:
Public MustInherit Class Column
Public ReadOnly Property ReturnSomethingUseful() As Object
Get
'return something useful
[code]....
But this gives the following error:
Public Overrides Function ParseValue(sValue As String) As Boolean'
cannot override 'Public Overridable Function ParseValue(sValue As String) As Object'
because they differ by their return types.
I accept that you can't do this, but I'd like to be able to preserve the semantics of what I'm. trying to do, which is to have an untyped version that deals with Object, but a typed version in derived classes that knows about the specific type T.

I am trying to construct a generic interface class with generic functions. My goal was to use this to implement multiple worker classes for database interaction that have the same basic functionality. Each class will deal with different object for example, category, product or supplier but unless the the functions in the interface are generic that this won't work.This is the interface code that I have but I don't know if I have done it correctly.

This is the generic type definition:

The compiler does not allow a "T" in the method's parameter because it's not defined, but I'm not sure how or where to define it. I thought it was okay to have a generic method definition.
