In the first case the compiler type checks that Bar.OnSomeEvent has the same delegate type as SomeEvent and inserts the Delegate.Combine call with the inferred delegate type.
In the second, you're doing part of the compilers work yourself by explicitly telling it the delegate type.
The msil code for both will be identical.

OK, thanks. So why are most of the samples I see written the second way? The first way is leaner. Is this some sort of leftover from older coding practices or something? Maybe .NET 1.x?

Thanks again.

It's a left over from 1.0 or 1.1, can't remember when they changed it.

It is only C# 2.0 (hence .NET versions >= 2.0) that support the shorthand notation.

How do applications get permission to create keys hkey_classes_root?

How do applications get permission to create keys hkey_classes_root?

Using Registry.ClassesRoot.CreateSubKey(...) I am able to add registry keys, however I wasn't able to until I messed around with the permissions in the registry. But I've installed other applications from the very same account before without changing permissions and those applications were able to add their owns keys to classes_root.

So the question is how do they do that? What code do I need to add to be able to let my program write to classes_root without the user who installs the program having full access?

Creating Tools > Options window

I am strugling with creating an Options Window (like how you go to Tools > Options and a window pops up with options in it).

Does any one know of a way to create this type of windows? Any Ideas, link to an article / white paper etc will be highly appreciated.

Thanks.

Just create a new form with the options, and from your main form button/menu item click/whatever, call it up. Nothing much really to it.

The window's not hard, you do that like any other window. What you need to decide is what all you will show, how you will store choices, and how the rest of you app reads and responds to those choices. I assume that's what you're talking about.

I don't know of an article specificly dealing with that, though many may have something like that built into articles about other topics.

Personally, I'd use XML serialization: decide what options to offer, build an XML structure to house them, make your options form address those options, read your config, and write to it. Then I'd probably have the host form show it as a dialog [optwin.ShowDialog()], and make it expose your XML serializable config object as a property so that the host can get the options directly from the options form. And make your host form look for the config on load to initially respond to saved options. But there are a number of things to consider and work out with this. Clear as mud?

Yes I am.

pretty much!!

I have the settings for my applications stored in the MyApp.settings file. Would that be a bad idea?

Also, when the settings are changed i.e. user has changed some stuff in the options window, the parent form doesn't autmatically apply the changes. For it to apply changes does it have to be "refreshed" or "reloaded"?

There's nothing wrong with using app.settings.

For the app to take advantage of setting changes, you can have the host form get the settings from the options form before it is disposed, or read them from your app.settings file after the options form is closed.

private void ChangeSettings() {
    MyOptionsForm mof = new MyOptionsForm();
    // show your settings form as a dialog
    // this line will show the form, and get the result when it closes
    // but you still have the mof reference to it, and can access it's
    // public properties.
    if (mof.ShowDialog() == DialogResult.OK) {
        // Make Setting Changes Here
        // Expose setting properties from MyOptionsForm
        // or re-read your settings file here.
    }
}

That help?

Hi Mona.

The things you ask for are so specific that you'd be guarantieed to get hits if you search for your topics on google.

Try searching for words like 'tutorial' or 'guide' combined with 'speech recognition', 'artificial intelligence', 'neural networks' etc.

Though 'artificial intelligence' spells ph.d to me Wink | ;)

Best of luck and happy hunting!

I'm trying to add robocopy to my yml file to help create artifacts. I'm struggling with the syntax, I think there are perhaps special characters or parsing rules for ps: or cmd: that I don't understand.

My goal is to invoke robocopy like this:

cmd: (robocopy XXX YYY) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0

per this article on straightening out robocopy's non-standard return codes:

http://superuser.com/questions/280425/getting-robocopy-to-return-a-proper-exit-code

My specific yml lines are:

before_build: 
  - cmd: (robocopy /mir . source /xd source external .git packages /NFL /NDL /NJH /nc /ns /np) ^& IF %ERRORLEVEL% LEQ 4 exit /B 0

what I get back in my build logs is:

'3' is not recognized as an internal or external command, 
operable program or batch file. 
Command exited with code 1
