if you just want to know how it was done, there're VNC clients on sourceforge you could look at the code for. Keyboard/mouse data can be captured/injected via global system hooks (there's at least one article on CP about doing this).

Hello all!
I have next task: If application is closed forcedly (with Task Manager, for example), I will need executing some logic.
What event or what mechanism I must use for implementing this task.
Thank you, very much.
Привет всем!
Есть задача: Необходимо выполнять некоторую логику, если приложение было принудительно закрыто (например, через диспетчер задач).
Подскажите, пожалуйста, в какой момент при каком событии я могу поместить эту логику, чтобы она корректно отрабатывала.
Большое спасибо.

I don't know if there are any, but if there are you won't find them documented on msdn.com so don't bother looking for the documentation.

There's two ways the task manager can close something, by using 'end now' you will get your OnClosing and OnClosed events (i think)
But if it just kills the process, you get nothing. Thats the point of killing a process, it stops dead, it lives no more, it has expired, it ceases to perform any tasks.

To prevent the process from being killed, be sure that nothing runs for extended periods on the main gui thread. This is because windows, upon receiving a user request to end task, will try to send a close message (firing the OnClosing and Closed events as stated in the previous post). However, you will not receive these messages if your application is running code in the gui thread, as the message pump is in that thread. So if your application doesn't close gracefully after some amount of time, windows will kill your process. I don't know if this is applicable to what you are doing, but something to think about anyway.

Hi All,
I have two forms in my app. I need to have functionality that when i click on nextButton on formA, formB should show and fromA should either hide it self or unload. Please help.
thanks,
Asif.

Set the forms' .Visible property.

Yup. Visible property would be good.
Try something like this:
this.Visible = false;<br />
FormB newForm = new FormB();<br />
newForm.ShowDialog();<br />
this.Visible = true;

That would imply the way you're trying to connect may not be right. Recheck the address and port number your app is using.

I did, more then onces, everything seems to be good

Are you using a proxy server to connect from your app? Your previous posts seem to indicate this. If so, set probably need to set your connection's .Proxy property.

I have a USB device I need to read from, the current software that runs the device has a lot of problems (needs administrator, crashed after 10 minutes, etc). The catch is that it is not a "human input device".
From what I have pulled from WMI, it uses the ClassGuid for a USB Hub ("{36fc9e60-c465-11cf-8056-444553540000}"). However, some USB snooping shows that the device has a bulk transfer end point, but only send information across the USB bus after the software is running.
Previous versions of the device were Serial/COM devices, so I am wondering if the "USB hub" has a hidden COM device on the other end.
Any advice on how to connect to the device would be greatly appreciated.

...How cool are they??!!
For ages I've wanted a regex facility on the String class, now I don't need to bother waiting for Microsoft never to add it as I can just write it myself in 4 lines of code!

Not that cool. Wait until you see how they get abused

Damnit! There I was being all optomistic and happy, and you had to come along and burst my bubble!

We'll see. I think extension methods are limited enough that there won't be abuse. I liken it to C#'s typedefing, e.g.
using Foo = blabhalbhabhalbahb;
..
Foo f = new Foo(); That feature was also open to abuse, as seen by all kinds of nasty C++ typedef'ing. C# limited its scope, and now we don't see abuse.
Likewise, I *think* extension methods won't be abused, or at least any abuse will be limited in scope, given that they have to be part of a static class and that consumers don't see them unless you specifically import that namespace. I think this limitation is a good one that will discourage abuse.

So for example you don't think this guy[^] is capable of abusing extension methods. I don't by it.

I don't buy it, either, because that's not what I'm saying. Most anything is abusable. Extension methods can be abused. But I think extension methods are limited in scope such that abuse is discouraged, and even when abuse occurs, it is limited (e.g. if I don't want to see your 420 extension methods on the string class, I don't have to).

Hmmm... now that concerns me, and I'll reread the spec, I don't want to be required to use the using directive just to use extension methods.
Can I please my wife by using extension methods?
