idea of a very special 'Menuitem'

Class is an instrument of object oriented programming.
Module is only file. wich can contain classes.
Module can contain several classes.

You'll learn more, after reading book about C# or object oriented programming.

Hello
I've got an idea of a ContextMenu containing special MenuItem's. I've spent the last hours with codeproject, google and a lot of coffee, but I can't find an answer. Perhaps it is very very simple and I'm just too stupid for a clear solution or otherwise it's not possible without writing a complete own implementation of a ContextMenu-class !?

ok, here you are :
I want to develop a 'customMenuItem'-class that can hold 3 or more icons/buttons (play, stop, continue) and a text entry, everything else should act as usual. I want to set a handler to each of the icons/buttons not to the text. I got no prob's with displaying my Items, but I don't found a way to set this kind of hanld or to decide on which button or Icon I've clicked (tryed with some x-positions-attributes).

ok, thanks for reading, but please do not answer with articles like 'how to build menu's with icons', they do not have different handlers for one item or don't analyse any kind of x-position inside.

thx's a lot for reading - sorry for my poor english

Play, pause, continue....

You can dynamicaly uptate one item, because when one of them enabled - other items disabled, why do you want to display them all ?

mh,
you are right - my example with 'play, pause, continue' is not the best. just imagine some more states or actions, that do not exclude each other.

thanks for reading my question and your fast answer

I think that MenuItem designed for single action.
Try using standart controls such as toolbar.
Or design "floating toolbar".

Hehe... Sounds like a very interesting problem...

I've done some stuff that's kinda similar, but means overriding the OnPaint method... You could always dynamically position your control according to the MouseClick event...

On_MouseClick(object sender, MouseEventArgs e){
if(e.MouseButton == MouseKeys.Right){
HoverControl control = new HoverControl();
control.Location = new Point(e.Point);
control.Show();
}
}

(Just typed that by hand... It's close, but capitalization and names might be off...)

Handle the closing of the control in the control. If you're working with a grid, you could use the object you've got in the selected row of the grid, and if no item selected, don't show the control.

Hope this helps...

Add link to exe file into Windows menu "Programs\StartUp" or
add key MyProgram = "c:\MyProgram\MyProgramm.exe" into registry path "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run"
(if you need to run program once add to path "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce")

The best way would be to get a book. And get a C# 2.0 book!

Updating ListView with Thread (+ extra thread questions)

Hello,

i am trying to keep updating a coloum for each ListViewItem in a ListView.

I though i could just do this by a thread that kept updating every 10 secound but i can see that it is only possible to update / change / work with the ListView from the Thread that originally created it.

Soo how can i achieve what i want ?

Should the thread which updates the ListView instead maybe call a method like Invoke(TheMethod) every 10 seconds, or how should it be done ?

Other Questions about Threads:

I seem to get into 2 usuall problems.

1. I only want 1 thread to be able to be created and working on a method. I usually solve this by declaring the Thread thread globally within the class, soo before i create the Thread i check if thread == null ( create thread ), and in the code which the thread is running i then set thread == null when it exit.

Is this okay ? or are there some smarter way to do it ? maybe some build in type / object or something ?

2. I only want 1 thread a time to run some code. Usually i solve this by declaring an Object threadLock globally within the class, soo i can just do lock(threadLock) { THE CODE HERE }.

Any better way of doing that ?

Best regards

That's one way to do it. If all the thread does is refresh the listview, you could use the System.Windows.Forms.Timer[^] class instead.

You could use the IsAlive[^] property.

That looks fine.

One reason could be that it's blocking the calling thread while it's working without any progress update.
