Re: displaying a baloon message from task bar - C# Discussion Boards

23-Mar-07 7:12

Hi everyone

Can anyone plz tell me how to display a message from the task bar in the form of a balloon. You know like when it pops up from the task bar when u are informed to get the windows updated or when u close the messenger window and it says that it’s still running. I’m working in Windows Server 2000 SP 4 right now.
I'm workin in a C# windows application
Thanks in advance.

To display an icon in the system tray use the NotifyIcon component. If you're using Fraemwork > 1.1 you can use its BalloonTipText and BalloonTipTitle properties to display a balloon tip.

well I'm using .Net 2.0 and I've already tried using NotifyIcon but it's not working. Probably I'm missing a trick here.
I've just made a new form for testing its functionality and I've coded like this

form1_Load()<br />
{<br />
NotifyIcon n = new NotifyIcon();<br />
n.BaloonTipText="This is the text";<br />
n.BaloonTipTitle="This is the title";<br />
n.ShowBaloonTip(5000);<br />
}

so now pz tell me what to do.
what I wanna do is to use this baloon tip to show an alert in my application and when the user clicks the baloon, it should open a new form.

The notify icon is not shown by default, so you have to explicitely set its Visible property to true. Furthermore, you have to specify the icon that should be shown in the tray (assign it to the Icon property). I guess the component will throw an exception or simply does not show if you try to show it without having assigned an icon first. Finally, register to the BalloonTipClicked to open the new form.

yes it worked when I assigned an icon to it but the strange thing is that the balloonTipClicked Event isnt working. its not responding at all. while the click and mouse click events are responding. is it bcz I'm using windows 2000 Server?? well it should be but... I can't see any other reason for it.

Maybe. Never used the balloon tip of the NotifyIcon myself, so I can't tell for sure. Try to run your code on some other machine and see if it works there.

yes thats a good idea. I just wantd to ask one more thing... can u give me a URL where I can find some useful icons? Coz I've seen ppl using v good looking icons but I still havent been able to find any of them on the internet.

In .net 2005 I have created Application

I want to create a log file, which maintains all the internal process so at the run time I want to create a file at the source

Code:

Private string LogFileName = "ADM_Log.txt";

LogFileName = Application.ExecutablePath + "\\" + LogFileName;

This return path like this

"F:\\Joe Don't Delete\\DotNet_Samples\\ADM\\ADM\\ADM\\bin\\Debug\\ADM.EXE\\ADM_Log.txt"

1. Why the path is return with \\?
2. If I use this path in

Code:
File.Create(LogFileName);

The error message is shown like this:"Could not find a part of the path 'F:\\Joe Don't Delete\\DotNet_Samples\\ADM\\ADM\\ADM\\bin\\Debug\\ADM.EXE\\ADM_Log.txt'."

If i give manually path with single \

It creates the File.

Then

I use this function to write information in the file
At first the file is created in single \ then it goes to this function
At first line of this function it throws message "the file is exclusively opened by another user"

Private void WriteLog(string sMessage)
{

StreamWriter sw1 = File.AppendText(LogFileName);
sMessage = ("::" + sMessage);
sw1.WriteLine(sMessage);
sw1.Close();
}

Please help me these all my problems

Thank u

Use Path.Combine to do this.

Are you looking in the debugger ? The debugger will render it like this

joerozarioia wrote:

This function tries to open the file. You have not closed the file when you created it, so you still have another lock on it.

Why do you need to provide four objects ? I never do. I think I set the Url directly tho.

Get the path in question ( the value of URL1 ) and try it in IE, to make sure it is valid.

Hi,
Here is the architecture.

There is a business layer set up as a peoject with a class i.e. class1

Class1 has two functions. One to populate a hashtable with 10 data and the other to count the data in the hashtable.

There is a windows service i.e. WindowsService1 that calls the populate function in the business layer.
The count on the hashtable is 10

There is another windows service i.e. windowsService2 which call the same businesslayer to count the hashtable. The couont on the hashtable is 0
Do you know why this is the case and is there a solution to this please?
Thanks

He's saying that each webservice will have an instance of hte class in their own process space. If you start Solitaire twice on your PC, the cards in one game won't change what the cards are in another. That's what you're trying to do, to make two programs share data.
