I was afraid of that...
The easier method is to not create the monitor process from the service. This is because the service will run without a user being logged in, and hence, there's no desktop to start the process on anyway.
You can use .NET Remoting to get status information from your service. Start the manager application out of the Run key in the Registry. This will start the monitor whenever a user logs in. This monitor can then contact the service over Remoting and get status information and updates through events over Remoting. Then the monitor can put up the icon in the Tray without any desktop problems.

HI Gurus. I am trying to generate a Table with dynamic controls in different
cells. I am at the same time generating Validation controls and assigning
"control to validate" property to the ID of the generated controls. The
generation works as expected, however when I press the submit button,
validation controls do not react. I posted the code below for the entire
table. In the last line I add the table to a session and regenerate the table
in the Page_Init between postbacks. Can anyone suggest why the validation
does not fire? BTW the "Causesvalidation" property of the submit button is
"ON". In advance, many thanks.
For counter = 0 To CInt(qty - 1)
tRow = New HtmlTableRow
tRow.ID = "fltRow" & counter
'mile cells
tCell = New HtmlTableCell
tCell.ID = "cellMile" & counter
tCell.Width = "20px"
txbMile = New TextBox
txbMile.ID = "txbMile" & counter
validator = New RangeValidator
validator.ControlToValidate = "txbMile" & counter
validator.Type = ValidationDataType.Integer
validator.MinimumValue = txbStartMile.Text
validator.MaximumValue = txbEndMile.Text
validator.Text = "*"
validator.ErrorMessage = "The value must be between " &
txbStartMile.Text & " and " & txbEndMile.Text
txbMile.Width = New System.Web.UI.WebControls.Unit(30)
tCell.Controls.Add(txbMile)
tCell.Controls.Add(validator)
tRow.Cells.Add(tCell)

Basically, you can't. Notepad doesn't expose any such API.
In theory, you could probably calculate it, but you would have to get the text from the textbox in Notepad, get the font that it's using, get the window dimensions, and get the status of the Word Wrap option. Not at all easy from your application, since Notepad doesn't support plug-in's.
Then you'll have to calculate the length of a line, using the Word Wrap status, window dimensions, font size, ..., yada, yada, yada, ...
It would be easier if you just wrote your own Notepad! Start with a TextBox on a form...

If your looking in TaskManager, then your looking in the wrong place to see how much memory your app is actually using. What your seeing in the memory RESERVED for the .NET runtime, or virtual machine, that your app is running inside of. This, by no means, is an indicator of your app keeping a stranglehold on that memory. The .NET Memory Manager will release any memory back to the system that Windows needs for other things.
And, no, changing the process priority will have no effect at all on that processes memory consumption.
Basically, there's nothing to do to get the memory footprint down. Just let the Memory Manager do it's job.
Now, that, of course, assumes that your code is written properly. If your allocating huge numbers of objects or keeping large numbers of records in datasets, unnecessarily, then you need to rewrite parts of your app to reduce it's memory consumption. But only you will know if that's even possible.

Hi Guys
I hope some body can help me, to tell me how to format decimal value wittout round up ?
Many thank for you
ICE

If you want to simply format have a look at the documentation of the formatstrings (i.e. tostring method documentation or format function).

Mr.Briga
Thank you for youra reply, actually I have ever tried to use Format string but I still got the decimal in rounding up state. The format string which was I used is "###.00"
I have a example:
I have three Textbox ( textbox1,textbox2,and textbox3) result from textbox1 divide to textbox2 will store in textbox3,
on textbox1 I enter 12000 and on textbox2 I enter 10039, actually the result must be 1.19 store in textbox3, but when I run this program on textbox3 I see 1.20 not 1.19 as I need.
Could you please to tell me how should Itype the right format on Textbox3 in order to get the right decimal format like I need.
Thank you
ICE

It seems from this article: VB Format string Rounding[^] that what you are seeing is by design.
I found this by googling "vb format string rounding".

Than it's more about rounding/truncating rather than formatting.
If you want to truncate to a certain digit you can use several approaches, two are here:
1)
Function TruncateToDecX(v as double,d as double) as double
v=v/d
v=int(v)
v=v*d
return (v)
end function
You use it passing v=1.1999 and d=0.01 (where you want to truncate) you get 1.19
2) Quick and dirty
dim s as string=v.tostring
s.substring(0,s.indexof(".")+2)

Hi all,
Someone say that, C# is stronger than VB.Net.
What do you think?
Can you help me to list the strength of C# that VB.Net hasn't.
Nice day.
Thanks.

This topic has been discussed at length on The Code Porject many times. Have a scan of the older articles and board topics and I'm sure you'll find something.
in summry - there are some differences between the languages and what they can provide function-wise, however it's really a matter of taste which language you use especially since they (mostly) compile to the same CLR for the .NET platform.
There are strong arguments for and against borh. I use both - most of my code these days is in VB because that seemed to be the 'lowest common denominator' (i.e. everyone understood it) but my background is largely in C/C++ so I sometimes feel more at home with C#.

Do you mean that you cannot scroll the text editor (source code) window using the scroll wheel on your mouse? If so, I don't believe that that window supports scrolling by that method.

I have VB6 code windows, and explorer and properties windows scrolling using Logitech Mouseware 9.79 software with an optical Logitech mouse on Windows 2000

The VB6 IDE does not support the mouse scroll wheel.

Yep. Upgrade to VB.NET.

Hi everyone,
Problem: Not able to initialize or set the selected index of a combobox after adding a datasource.
Situation: a combobox set on a usercontrol. The user control is set onto a form. The initialization or resetting of the selected index occurs within the load function of the usercontrol. I can reset the selected index on load if the code is within the form load function, but once I move the code to the usercontrol load function I cannot reset the index until another event is fired.
Tried: I have tried to set the selected index to -1 twice, I have read that the .net comobox has that quirk in it.
Code:
Private Sub UserControl1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call loadData()
Call Me.combobox1.selectedIndex = -1
Call Me.combobox1.selectedIndex = -1
End Sub
Does anyone out there know why this occurs and how I can solve this problem? or maybe a url/link to a solution to this problem? Thank you for looking at the post and all your help everyone.

Can some one help me? I just migrated an App in 2003 to 2005 but I used Hash method to encrypt and decrypt a value but in VS 2005 I didn't give the same result as in VS 2003 is written in C#
It's suppose to send a string and give me numeric value back but I run it and it's not the same value in the app made in 2003 that in 2005

You used what to encrypt your string? 
That wasn't a good idea. You just found out why.
What's wrong with using the encryption classes built into the .NET Framework? They follow standards-based encryption algorithms and work the same from .NET version to .NET version.

I've created a Crystal report which connects to an Access database to get its data. I have a Crystal report viewer control on my VB form to view the report. When I run the app on another computer and try to view the report a database login screen comes up. The screen has the wrong file path to the database it is trying to connect to. Typing in the right path makes it work but how can I have it automatically know what the correct file path is?
Thanks
