View 1 RepliesApplication_Start Versus OnInit Versus Constructor?
Jul 23, 2010I've gone rounds with this ever since I started programming classic ASP 12 (or so) years ago and I've never found a great solution because the architecture of ASP and ASP.NET has always been a swamp of bad practices, magic shared singletons, etc. My biggest issue is with the HttpApplication object with its non-event events (Application_Start, Application_End, etc.).
If you want to do stuff once for the entire lifespan of an HTTP application, Application_Start is the obvious place to do it. Right? Not exactly. Firstly, this is not an event per se, it's a magic naming convention that, when followed, causes the method to be called once per AppDomain created by IIS.
Besides magic naming conventions being a horrible practice, I've started to think it might be a reason there exist no such thing as a Start event on the HttpApplication object. So I've experimented with events that do exist, such as Init. Well, this isn't really an event either, it's an overridable method, which is the next best thing.
It seems that the Init() method is called for every instantiation of an HttpApplication object, which happens a lot more than once per AppDomain. This means that I might as just put my startup logic inside the HttpApplication object's constructor.
Now my question is, why shouldn't I put my startup logic in the constructor? Why does even Init() exist and do I need to care about Application_Start? If I do, can anyone explain why there is no proper event or overridable method for this pseudo-event in the HttpApplication object?
And can anyone explain to me why in a typical ASP.NET application, 8 instances of my HttpApplication are created (which causes the constructor and Init to run just as many times, of course; this can be mitigated with locking and a shared static boolean called initialized) when my application only has a single AppDomain?

C# - Trigger On Database Using A Web And Winform Application
May 25, 2010Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how.
View 1 RepliesC# - Can Create A PDF Quotation File From Winform
Aug 6, 2010Assuming i have a winform that has a button called "Create a Quote". Once user clicks it, a PDF File gets created on desktop. The PDF File has a fixed design/structure e.g. the logo is at the top left corner, the headers are fixed, etc. However, the data it self is pulled from a database.
As you see above, Quotation #, Description, Qty, U.P (USD), T.P (USD) records should be fetched from the db and dumped in the pdf template then create the pdf for user.
C# - Is There Equivalent Of WPF OriginalSource Event Property In Winform?
Jan 23, 2011From:
[URL]
The OriginalSource property of the object identifies the original object that received/initiated the event. Consider a custom control (called CustomControl1 in this example) that is composed of a TextBlock. When a MouseDown event is raised on the TextBlock, the OriginalSource property will be the TextBlock, but in CustomControl1's handler, the Source will be changed to the CustomControl1 object so that other elements along the event's route will know that CustomControl1 received a MouseDown.
Is there equivalent of WPF OriginalSource event property in Winform and ASP.NET ? If not how to emulate this ?
