There is a utility called 'TaskManager Extension' in CodeProject. I think that should be able to address your requirement. Since the code is also there, you should be able to follow this requirement soon. Check out

[WPF] ICommand woes....

I tried to create a SetColor command and a ColorPicker which uses it.

There is one effect I cannot reproduce, it is tracking the CommandSource and wether it's valid.

By that I mean if I create a MenuItem like that:

<MenuItem 
     Header="Blue" 
     Command="{x:Static local:MyCommands.SetColor}" 
     CommandParameter="{x:Static Colors.Blue}" />

It enables/disables depending on wether the currently focused element respond to the SetColor command.

But my ColorPicker never get any CanExecute or whatever event call, therefore I cannot update it appropriately (i.e. enable/disable) when the focused element change.

I implemented ICommandSource, used a RoutedEvent, I never get any relevant info....

Any idea what I could have missed?!?

found it!

it's quite tricky, I remember read about it in a blog 6 month ago but it's nowhere in the documentation!!!
(Thanks Reflector)

RoutedCommand.CanExecuteChanged strore the event handlers as WeakReference.
Therefore you have to hold a reference to the handlers your self if you want your event handler to be called....

I'd be more inclined to think the textbox is for the name of a server, than that every control he runs on the server side is named serverTB or serverLbl or serverDDL

It's certainly worth asking, before making oblique references to CSS

Hi,

u can use this code to set the text color but u cannot set the font size as it is read only and u have to set it at the design time itself:

<br />
textBox1.ForeColor = Color.Red;<br />
textBox1.Text = "Welcome";<br />

even if u try assigning size to the Font.Size property, the code wont complile.

How to load and run non .net exe in memory?

Hi!
I'm trying to load and run a non .net application in memory by loading it as an embedded resource using Assembly.Load() and then invoking it. It works for .net applications but not non .net ones. I've tried.
Could anyone please guide me in this area?
Thanks!

Process.Start is the way to do that. The assembly stuff works for .NET stuff only.

How can I access the App's tab in the task Manager

Hello, How can I access the Application tab in the task
manager, I’m not talking about the process' name because an App Can have associated a
process with different name, I need to know that because sometimes happens that when you
exit an app. The process still remains in the process tab, so if it happens I
can ask for the name of the App and kill the process.
thank you in advance!!!

You can't. Your best bet is to fix your app so that it closes properly. Your app can close it's own process, if it does this, it's not running, so how can it close itself again, and why would it use an external method to look up it's own process ?

Thank you for your answer, here I’m going to explain you what my problem is about:
My Application runs several installers (the installers are for example mysql, odbcConnector) and each one waits for the previous installer to finish to go on to the next one, they all request the windows installer(msiexec.exe) and that’s my condition for waiting(process.WaitForExit()). In a normal situation (context) when I finish the installation or cancel an installer, it closes the process msiexec.exe however very often happens that it doesn´t close the process msieexec.exe that´s why my Application doesn´t continue to the next installer. Perhaps you´re wondering why I don’t use the waitforexit directly for the Installer and that´s because it doesn´t wait.
Thank you very much for your help.

Jose Guzmán.

Hello it´s me again, I just realized that when a Installer is runing there is two windows installer instances, the first one is Current user instance and the second System´s, so I´m gonna ask for the current´s.
Thank you

I have an application it is tabbed based and holds a texteditor in each tab (The ICSharpCode TextEditorControl). I can open as many tabs as I want but when I switch bewteen 2 or three tabs I get this error.

I'm am getting "Object reference not set to an instance of an object" result back. Problay somthing small I am missing somewhere, but I can't see where.

Below is the code for when a tab switches.

void TabControl1SelectedIndexChanged(object sender, EventArgs e)<br />
		{<br />
			if(tabControl1.TabPages.Count > 0 && !tabControl1.SelectedTab.Disposing) {<br />
				openFile = tabControl1.SelectedTab.ToolTipText;<br />
				<br />
				if(lengthSet == false) {<br />
					if(oldLength != tabControl1.SelectedTab.Controls["textEditorControl1"].Text.Length)<br />
						oldLength = tabControl1.SelectedTab.Controls["textEditorControl1"].Text.Length;<br />
						<br />
					if((bool)tabControl1.SelectedTab.Tag == true) {<br />
						saveToolStripMenuItem.Enabled = false;<br />
						toolStripButton3.Enabled = false;<br />
					}<br />
					else {<br />
						saveToolStripMenuItem.Enabled = true;<br />
						toolStripButton3.Enabled = true;<br />
					}<br />
				}<br />
			}<br />
			lengthSet = false;<br />
		}

The Line
if((bool)tabControl.SelectedTab.Tag == true)
returns the error

If I add

<br />
TextEditorControl editor = (TextEditorControl)tabControl1.SelectedTab.Controls["textEditorControl1"];<br />

and replace the line with the error with
if(editor.IsReadOnly)
It still returns the same thing.
