hi

i have a question about help file button and f1 keydown property in c#.

can we have in a form help button and keydown property about help(with press F1 key) ?

i use the following commands for the key :
-------------------------------------------
if (e.KeyCode == Keys.F1)
{

Help.ShowHelp(this, "Help.chm");
}

and for the help button:
-----------------------------
Help.ShowHelp(this, "Help.chm");

But only one of the two methods are working the other one activated when start other one method.
for example if when i press F1 key is activated the help file then if i press the help button will work too but if i close the running program and i will start again and press help button without press f1 key before then the button does not working.

C# desktop type ahead

I am writing a new C# 2010 desktop application. This application will allow users to select a file from a specific directory location. I am wondering is there anything in a windows application called 'type ahead' feature? Basically
the user will stat typing a few letters and all the files in a selected directory path will appear. (I am asking this question since this feature is available in web applications.)

If there is this type of a feature, can you tell me what this feature is? In addition can you tell me and/or point me to a reference that will tell me how use the 'type ahead' feature?

Its called AutoComplete.

Here's a reference:

You will have to create a custom provider or fill the provider using System.IO methods to enumerate the sub-directories in the current parent directory.

public void Foo(Bar bar)
{
    if (bar== null)
    {
        bar = new Bar();
    }
    //Do something with bar;
}

--- or ---

public void Foo(Bar bar)
{
    bar = bar ? new Bar();
    //Do something with bar;
}

Which do you think is better?

[Edit]
Thanks all for your help. I opted for 1 (it was the original code so I know it'll make it through the code review) and easier for newer devs to understand. I might drop the {}.
