Short answer: test it

I took a little look with the Reflector and I'm willing to hazard a guess: the first one. Because: the first one just calls Number.Format(something) which is an extern function, the second one calls int.ToString(some stuff) so basically it just adds a method call (which could be inlined by the JIT engine) and the last one also does some string appending, to which JIT magic may also happen, it might have an "if (first.Length == 0) return Second" and then the optimizer in the JIT compiler might decide that since the string is a constant, its Length is also constant, and then it might optimize that test away and skip the string appending completely.
That is very optimistic.

So, still test it..

Who knows, maybe it's even possible to write a faster IntToString method? I would look into it. Especially if a lot is known about the input (probability distribution etc). I wouldn't count on it, but you don't know until you try..

Re: which one will be faster?

I don't know exactly. Test it!

However if you use a lot of int to string and then something like "string total = a+b+c+.... "
where a,b,c are strings obtained from ints than StringBuilder is the fastest and less
memory hungry.

Google for "Windows 7 Taskbar .NET Integration" and you'll find an SDK you can use that might supply what you need.

In the user interface designer you can change the banner bitmap property to your own image.

If you have knowledge, let others light their candles at it.

Not in the Visual Studio designer, though I believe you can control that if you use WIX[^] or some other installer designer to create your installer package.

How to convert a Control into a ToolStripButton

ArjenGroeneveld11-Jan-10 22:07

Hello, I have a routine that loops through all the controls on my form.
The purpose is to set the Edit Mode or Read Only mode.
To find textboxes and buttons inside a TabPage or GroupBox the routine runs recursive.

To convert a Windows.Forms.Control in to a Texbox I validate and use ..

if (c is TextBox)
{
ToggleTextBox((c as TextBox), flgEditMode);
}

So Far So Good.

If I do the same for a ToolStripButton I get the message:

Cannot convert type 'System.Windows.Forms.Control' to 'System.Windows.Forms.ToolStripButton'

Please can you help me with a work around?

Kind regards Arjen

Hello,

The ToolStripButton class doesn't Inherit from Control.

Inheritance Hierarchy:
System.Object
System.MarshalByRefObject
System.ComponentModel.Component
System.Windows.Forms.ToolStripItem
System.Windows.Forms.ToolStripButton

So you have to look for the ToolStrip class (which inherits from Control) an than iterate over the Items property.
Like this:

foreach (Control c in this.Controls)
{
   if (c is ToolStrip)
   {
       ToolStrip ts = c as ToolStrip;
       foreach (ToolStripItem tsi in ts.Items)
       {
           ToolStripButton tsb = tsi as ToolStripButton;
            if(tsb != null)
            {
                ...
            }
       }
   }
}

Hope it helps!

All the best,

Martin

It's done the exact same way you wire up any other event in C#. Lesson 1[^]
