how to send data to website without open the browser - C# Discussion Boards

Depends on how many objects of your class you'll have/load at a time.
If you have many each of them keeping a few mb of data, not so OK.

A different approach(that I mostly use) is to create separate methods in the "DataLayer" one that loads
only id and name(null or zero sized/empty byte[]). And another one thatn loads the byte[] too, or maybe just the byte[]
for a given ID.

That way a much lower impact on memory and speed too(given that the byte[] can be easily retrieved by using the ID
in the DB if any). In other words load the few mb only when required/needed.

My post/answer utterly assumes that there is a DB somewhere. If not, please ignore it.

All the best,

Dan

Sure, but maybe it needs a ToString method?

yes i know there *are* pointers in c# but they are not the *preferred* way of writing c# afaik

if i wanted to write my code as i see best i wouldn't use .net for anything but i am trying to do things right

Use the existing class.

You can always use pointers in C#. Its called unsafe code.

(Proper) Last chance exception handling [modified]

Deian22-Jul-11 4:35

Hello,

I've read tons of materials all over codeproject and google about last chance exception handling. Most of the suggested solutions include subscribing to Application.ThreadException and AppDomain.CurrentDomain.UnhandledException to handle both exceptions in current and different thread context. Under debug configuration the exceptions are caught as expected, but under release the CLR unhandled exception dialog is shown and the handler is not invoked.

What is the proper way of handling ALL exceptions (as to provide logging before exit) in WinForms application?

I've attached a handler to AppDomain.CurrentDomain.UnhandledException with good results. You need to do it before you call Application.Run, though.

Re: (Proper) Last chance exception handling

Deian25-Jul-11 4:49

It is attached at the beginning of Main() (much before Application.Run) as follows:

[STAThread]
static void Main()
{
 Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
 Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
 AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
 ...
}

Did you catch the exceptions under Release configuration?

Yes. I didn't even do the first call. It is only for exceptions in the UI thread, though ... I don't have a ThreadException handler (all threaded code is self-protected).

Hello coders
I want to know what will be the main features we have to use to increase application performance. Specially for data updations. There are many available but I want to know the best one.

Any help.
