You could type "animated image" into the search box on the home page of CodeProject and find this article.

So I can't create animation and store it in Image class?
Thx anyway

He didn't say that.
He said "You could type 'animated image' into the search box on the home page of CodeProject..." ! Then you can click on and read the appropriate articles returned by the search function.

There are NO articles about 'animated image'
The most appropriate was "NGif" article about creating .gif using separate class.
But I need to store animation in Image class in some way.
And .gif has only 256 colors - I need 24bit color.

How to cancel a tabcontrol selectedindex event?
I can't find a proper event to do this.
in 2.0 framework, some events were added:
Deselected : Occurs when a tab is deselected.
Deselecting : Occurs before a tab is deselected, enabling a handler to cancel the tab change.
but how is it possible in .net < 2.0 
thanks in advance,
Niko

You could hack the change by creating your own derived class from TabControl and just monitor the SelectedIndexChanged event. The following code will prevent a user from selecting the third tab in the MyTabControl class.
using System;
using System.Windows.Forms;
namespace WindowsApplication1
{
public class MyTabControl : TabControl
{
private int lastSelectedIndex = 0;
public MyTabControl() : base()
{
lastSelectedIndex = this.SelectedIndex;
this.SelectedIndexChanged +=
new EventHandler( SelectedIndexChanged );
}
private void SelectedIndexChanged( object sender, EventArgs e )
{
if( this.SelectedIndex == 2 )
{
this.SelectedIndex = lastSelectedIndex;
}
else
{
lastSelectedIndex = this.SelectedIndex;
}
}
}
}

Hi All,
I want to add a contextual menu item when the user drag and drop any
folder or file using right mouse button from local folder to a shared
web folder or vice a versa.how can i achieve this and which interface
i have to implement and where in registry i have to register it.using
icontextmenu and ishellextinit interface and registering them for
HKCR\Folder\shellex\dragdrophandlers and
HKCR\Directory\shellex\dragdrophandlers works for local folders and
network share folder but it does not work for shared web folder which
generally comes under my network places .i also tried registering it
under HKCR\Network\shellex , although there is no dragdrophandlers key
is beneath it so i created one and under it i registered my shell
extension and also tried by registering my shell extension under
HKCR\Network\shellex directly.can anybody tell me how to do
this.Thanks in Advance.

Hi all,
I always wondered, when using the lock statement, people lock other variables that the one which we want to serialize access to. Eg, if we want to serialize the call to a static int(varname++;), why do we chose to lock on another variable? Do we assume that whenever we will want to access this variable again, we're going to check if this variable has been locked previously?
Thanks

They do it as a matter of convenience; the variables on which they lock will always exist.
In C#, for example, let's say we want to access an instance variable within the class from more than one thread running within the class. So, we'd lock on the instance of the class since we know the class exists since we're running those methods!
lock( this )
If we want to access a static variable within a class from more than one thread, we use the runtime information to lock on that class, since we know the class exists, since we're attempting to change the value of a static variable contained within it.
lock( typeof( MyClass ) ).
I hope that makes sense.

I have a problem!
i have an Array of buttons, and all of the buttons are connected to one event, let us say OnClick Event, now when i get in to the Event function i Cust the sender to a temp button in the function but the problem is that i want or better say need the buttons indexes becaue i need to check the buttons around the selected one.
How can i solve this problem?
Thanks you all!

Store the button index in the button's Tag property
|
|
|
|
|
What do you mean?
please give e.g.
Thanks
|
|
|
|

What the last free name means is the following:
Button[] buttons = new Button[ numberOfButtons ];
for( int i = 0; i < numberOfButtons; i++ )
{
buttons[ i ] = new Button();
buttons[ i ].Tag = i;
buttons[ i ].Text = String.Format( "Button {0}", i );
}And, in your button click event handler
Button b = ( Button ) sender;
int buttonIndex = ( int ) b.Tag;

what about a Matrix? [,]?
|
|
|
|

Okay, I don't know the specific class Matrix to which you have referred. However, let's assume that you have a Matrix class that acts like an n x m array of objects. Then, you could have the following code:
Matrix m = new Matrix( n, m );
for( int i = 0; i < n; i++ )
{
for( int j = 0; j < m; j++ )
{
m[ i, j ] = new Button();
m[ i, j ].Tag = new int[] { i, j };
}
}
And you could then acess the button in your event handler like so:
Button b = ( Button ) sender;
int[] index = ( int[] ) b.Tag;
That would then contain your index where the row index is in the first entry of index and the column entry in the second.

i have a point.
how to compare this condition
PointF point=new PointF();
point = x.Intersect(y);
first time i am getting (429.5,215) as point
next time i am getting (+infinity,NaN) as point
So I like to have point which is having values in the point(numerice values).but not infinity or NaN
for this only I need to write (If condition).
if(point is not infinite)
{
}
if point is infinite then it not should enter in the if condition.
sometimes i get infinite values in the point.
what is the syntax for the above one.
Please help me out.
Thanks in Advance

PointF holds onto 2 float values... float, like any other datatype, has finite values - what do you mean by the following line

|
|

|

Something like this:
PointF point;
if (!float.IsInfinity(point.X) && !float.IsNaN(point.X) &&
!float.IsInfinity(point.Y) && !float.IsNaN(point.Y))
{
}

After years of development I get to my first multilanguage application, and I have a problem.
The windows forms part is almost ok: create the form with localize true, design it for default, after that load the form for every language, edit every text of every component - quite annoying.... but it works.
The problem is with strings (messages to the user). My first idea was to store them as resource strings, but resource does not have a language so a winforms-like approach not works. Now I store strings in external text files but this way is plain ugly.
Please, please shed some light - what would be the good way...
(using Visual Studio 2005)

Have you tried creating a resx file for each language using the appropriate name (see the name of the resx files created by Visual Studio for the dialogs to determine the name)?
Sorry I can't say anything for sure, I have only been doing enterprise level localization which involved a home build localization tool compiling the resx files. If you are going to do a reasonable size project, or more than one or two languages, consider buying a localization tool - they work MUCH better than VS (even though the tools you an buy are actually pretty bad they do have basic functionality missing in VS).
