events and functions - C# Discussion Boards

I am using visual studio 2003. My application is a window application and i am using C#. I want to put double click event for each row in the datagrid.

Can anyone help me please.

If there isn't one, you can catch a single click, store the time it occured and on the next click see if they were close enough together to make a double click.

Hehe, so you get blamed for the lack of functionality. I sometimes wonder what goes through the minds of some characters.

I guess then page need to post back two times, right ? How about hooking JS double click event and raising postback manually ? I haven't tried it, but a wild guess.

BTW, don't know why you got down voted.

Aren't there data grids in winforms ? If this is an ASP.NET question, it's in the wrong forum.

Oops, I am sorry. I forgot which forum I am in. Sorry.

*grin* It did occur to me that the question is ASP.NET, but I act dumb until it's clear, and assume the question is in the right forum.

what is the basic difference between evemts and function.
i know events execute a handler and function are user defined.
but unable to understad the difference

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

correct

It's what you said. An event is something you can subscribe to, to be informed when something happens. The event will call functions, but most functions are not attached to events.

Hi.

I wanted to remove Vista security notification balloon that pops up when you deactivate UAC (User access control).

I need to do this in an application written in C#, I can easily do this in a cmd, but it does not seem to work in C#.

I write this in the CMD:

REG DELETE "HKCR\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}" /f

So I created this C# code:

CreateProcess("reg.exe", @"DELETE \"HKCR\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}\" /f");

Create process creates a new process with reg.exe as an application and the delete as argument.

That does not work. Any ideas?

Yeah, try writing some code that accesses the registry directly instead of trying to duplicate your command line code.

That was fast.

I already tried that. Se my other reply.

By the way, I did also try another way:

RegistryKey key = Registry.ClassesRoot.OpenSubKey("CLSID", true);
key.DeleteSubKeyTree("{FD6905CE-952F-41F1-9A6F-135D9C6622CC}");

but it tells me that the subkey does not exist.

I tried to print out all the subkeys:

foreach (string str in key.GetSubKeyNames())
{
Console.WriteLine(str);
}

Every key comes out.. so i'm in the right place, but the key I need does not show.

If the key does not exist, then you've done it, right ?

I have no idea if what you're trying to do work. But, the code is right.

I think it's because Vista can do magic.

At least it seems so.

----

C:\Users\Mads\Desktop>Rege.exe
Disable security notifications

C:\Users\Mads\Desktop>Rege.exe
Disable security notifications

Unhandled Exception: System.ArgumentException: Cannot delete a subkey tree because the subkey does not exist.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at Microsoft.Win32.RegistryKey.DeleteSubKeyTree(String subkey)
at Rege.Program.DisableSecurityNotifications()
at Rege.Program.Main(String[] args)

----

So it does get deleted. But then i fire up regedit and see for my self. And there it is.
I can even edit it's values and create new subkeys in it.

I tried restarting, and the subkey is still there in regedit.

I found someting.

When i delete the key:
HKEY_CLASSES_ROOT\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}

it deletes the key:
HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{FD6905CE-952F-41F1-9A6F-135D9C6622CC}

I'm running 64bit Vista. I guess they made it that way, so that Vista 64bit would be more backwards compatable.

Oh - I think if you try to access the registry without permission, it creates a copy you can play with. I reckon that's happening to you. Vista is a pile of crap

Agreed!!!

-= Reelix =-

How insightful.

Please go tell someone else about your feelings for Vista.

No, It is in fact a part of the registry that enables 32bit backwards compatebility.

I compilled my application for 64bit instead of 32bit, and it deletes the correct subkey now.
