Simple class for easily minimizing to tray and adding context menu with ONE line of code

Download source files - 5.95 Kb

Introduction

I usually like to implement the minimizing to the system tray feature in my applications... In addition, I also like to add a context menu to the icon which allows the user to restore the app from the tray or exit. After adding the same several lines of code to each application, I realized that it would be beneficial to streamline the process.

The Class

This class allows you to add this functionality in one line of code. The constructor takes the main form (Me) of your application, the text to add to the icon [optional], and the icon you want to display in the tray [optional - defaults to application icon].

Example:

Dim minToTray As New ClsMinToTray(Me, "MyApp is running...", myIcon)

Options: You can also choose the window state on restore and add to the context menu (the default tray icon menu has two items - Restore and Close).

Example (choose window state):

minToTray.restoreWindowState = FormWindowState.Maximized

Example (add to default context menu):

Private Sub Form1_Load(ByVal sender As Object, _
             ByVal e As System.EventArgs) Handles MyBase.Load
  minToTray.trayMenu.MenuItems.Add("New Menu Item", _
                          AddressOf NewMenuItem_click)
End Sub

Public Sub NewMenuItem_click(ByVal sender As Object, ByVal e As EventArgs)
  'Code Here
End Sub

Notes

This class seems to work well for me. I have used it in both VS2003 and VS2005b applications. The only issue I have ran into is in VS2005b. The ShowInTaskbar property of the main form (on multi-container) application seems to cause some anchoring problems (forms layout is affected on restore). I'm assuming this is a VS2005b bug...or maybe I'm missing something.

Hey,

Thanks for this code, it is really useful! Just to be picky, in the clsMinToTray class, you might want to turn the public fields "trayMenu" and "restoreWindowState" into properties. It's not essential, but it looks a bit more professional to those who call it from code :P

Apart from that small nitpick, once again thank you for this awesome code! I'll start using it straight away.

TrayText Property

Fluid Dynamics Software

Hi,

First, thanks for the class, I always like when things are made easy....

I wanted to be able to update the text that appears in the tray (percentage complete) so I added the following property to the class:

Public Property TrayText() As String
   Get
      Return trayIcon.Text
   End Get
   Set(ByVal Value As String)
      trayIcon.Text = Value
   End Set
End Property

Works for me, maybe someone els ecan use the modification.

Can't get it to work...

I love the idea, the simplicity - and I think you've done a great job laying out the functionality for this task... but I cannot seem to get it to run. I'm not sure of the problems, but I've been try for a couple of days off and on to see if I can debug the issues, but to no avail. I have even downloaded the sample programs you posted to an earlier user's questions and remarks, but it fails to run on my setup or a corresponding setup I have nearby. Both use Microsoft Windows XP with Visual Studio .Net 2003. If I resolve the conflict, I'll be happy to post my findings. Otherwise, great job! (And I say that because it is obvious from the postings that it works for some people just fine.)(I'm a BIG advocate for wrapping functionality as tight as you have done so here!) Smile | :)

Restore and AxMediaPlayer

JLCarbwood

Hi Chris,

I just found this class and its very nice, easy to apply to my application.

The one question I have is,

1 of my application use axmediaplayer.dll and when it's minimize to the
tray, and restore again the application restore fine, but the player size
change to the maximize size. I look thru the class and try somethings here
and there, but no luck.

I'm very new in programming, so maybe it's something very simple but I can't
picture it.

Thank you,

Jorge

Hi Jorge,

Although I am not familiar with the axmediaplayer dll, I would assume that the problem is likely with anchoring. Is the media player within your main window? If so, make sure you set the anchoring property correctly. The class changes the size of the main form (Me)...so if objects on that form are not anchored properly, there can be some problems when restored.

If you continue to have problems, let me know and I will try to help. If you like, you can send me your app and I can take a look at it.

Most people think that programming is an exact science...HA! Confused | :confused:

Later,
Chris

Urgent Help Needed :context menu does not appear

Hi, I am writing a c# code that opens a file and searches for some condition and according to the condition that occuring tray icon changes.This should be done every 10 minutes.

I have coded this part well but I can not exit my application from a context menu item(exit) which never appears.

If I erase the line where my while loop appear, context menu appears and every thing goes well.

Do you have any suggestion where I might have made a mistake? I am a c# newbie and I cannot find the solution...

thanks for your help very much..

Hi,

I'm not a C# programmer...
But, are you not disposing the notifiyIcon on every trip through the loop (see below) - I think this will dump your context menu?
You are then assigning an icon to the notifyIcon on the next trip...but no context menu.
By looking at the code, I'm not sure why you are disposing the notifyIcon on every loop (Although, I'm sure you have a reason). Could you not attach the context menu each time you assign an icon in the loop?

Hi, To be honest with you, I don't know. I have done very little in PPC development. You might give it a try and see if you can get it to work. If you can, let me know. I would be interested in what tweaking needed to be done (As I doubt it would work without it). Wish I could of been more helpful, Chris

20:27 10 Jul '05

Hi,

its nice to see your solution infact i was looking for one like that , but i cma unable to use your class .
Actually i want to add item to the context menu which will be shown in the SYStray and also with the text i want to display icon in the context menu.

Can you send me an example of how to use your class.

Early response will be appreciated.
my mail id is bhanu.prakash@airtightnetworks.net

Hi, Glad this is proving useful for you. I made a very simple sample application with three different contructor setups (just uncomment the one you want and comment out the others). The example can be downloaded here. [I will also email you a copy] If you have any more questions, let me know. Thanks, Chris
