Is there a colour picker in C# to choose from the Color enumeration by color or name ? If not, I thought I might write one, but I'd hate to do it and find out there's one as standard....

Just the good old Color Dialog is truly documented.
I did notice a number of color pickers in the C#/Controls section here on Code Project.

 What?
Did you try the indexer?
i.e.
MyObject o = (MyObject) myArray[i];
.

In C++, I would declare my data values as private members with public get/set methods. I can do the same thing in C#, but I can also use properties. Any guideance on when to use one vs the other? Is there any performance/size difference? Thanks

Properties basically accomplish the same thing. Each propert should have an accompanying private field for the actual value. The only advantage is that you can do this :-
abc.val = whatever;

You should use properties when you are dealing with storing the data in a private variable.
You should use Get/Set methods when that data is NOT being stored cannot be accessed as quickly as a "return myPrivateData;". Some applications of this type would be retreive the customer name from the database; return all the prcoesses running on the system, etc...
The line is a fine one and its quite elastic so just go with what feels right

Stick with Properties when appropriate.
The Property Grid likes them, the debugger likes them, and Serialization likes them.
Go with the flow, it will make your life easier...

Hi All,
Quick question here, I need to check to see if a cookie exists when someone enters 1 of my pages.
This is an intranet so I know that everyone accepts cookies but is there way to see if a certain cookie exists? 
Thanks,
Gavin

Check the cookie for null

Tried that,
for some reason the page falls over if I try the following
if (HttpContext.Current.Request.Cookies["NewOutbreak"]["Test"] == "")
{
//Do Something amazing
}
else
{
Go home
}
I get an error saying something like cannot check for null as it doesn't exist.??

I wonder if you are getting the error from the "NewOutbreak" cookie not existing and then trying to access it.
Give this a shot...
<br />
Request r = HttpContext.Current.Request;<br />
if(r.Cookies["NewOutbreak"] == null)<br />
{<br />
}<br />
else if( r.Cookies["NewOutbreak"]["Test"] == null)<br />
{<br />
}<br />
else<br />
{<br />
}
I'm still working out your issue at the top

I see the logic, you have to check to see if the Cookie exists before checking to see if the cookies key exists or has any data...
Seems to be 100% Thanks

Hi,
How do you make a text box on a windows form accept numbers only?
These is really easy in VC++ 6.0, can't be hard in C#
Cheers

there's already a thread about that problem in this forum (currently on the next page)

I know two way for it.
One:
http://www.codeproject.com/cs/miscctrl/maskedcsedit.asp
Two:
Handle KeyPress event of text box yourself:
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(e.KeyChar < 48 || e.KeyChar > 57 )
e.Handled = true;
}

You must write an article and quote your site.
i thinks programers believe it's commercial if u didn't (boring after all you efforts)

I created a custom control derived from a panel in which I added flat buttons but how can I add action on the buttons dynamicly ???
I can't because the class is derived from a panel.
Anybody can help me ?
|
|
|
|
|
You could expose your buttons via a property as a collection (of buttons). But then you are exposing everything about the buttons.
|
|
|
|
|
Doh! Then again, there is nothing stopping you from accessing the built-in Controls collection of the Panel and attaching an event handler dynamically.
|
|
|
|
|
You can expose event properties on your control; like so...
public EventHandler ButtonA_Click
{
add
{
buttona.Click += new EventHandler(value);
}
remove
{
buttona.Click -= new EventHandler(value);
}
}You wind up with having to name the events something different, but you can control what events are available.
HTH,
James

The problem is that I create only one instance of a button and Each I wrote tb.AddItem("Test",Color.Black,Color.White,0); (that's an example)
the control add a button itself to the parent control which is a panel.
so how can I handle all the buttons actions when I have only one Button Instance ??
can I make a function like ItemClick(int index,EventHandler action) ??
if yes can u plz give me some code because I try to use this with a switch statement and I got an error :
"a value constant is expected"
Thanks
