Hi, i found how to get my application in system tray. The problem is when i want it to go in normal state. My app only want to go in maximize state. Here's my code
Private Sub Main_SizeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.SizeChanged
If Me.WindowState = FormWindowState.Minimized Then
TrayIcon.Visible = True
Me.ShowInTaskbar = False
End If
End Sub
Private Sub TrayIcon_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TrayIcon.Click
'Ouvre l'application main window si on click sur l'icon dans le tray
Me.ShowInTaskbar = True
Me.WindowState = FormWindowState.Normal
TrayIcon.Visible = False
Me.Show()
End Sub
Thx in advance!

That's ok i found the solution
When the window is minimize i don't have to put Me.ShowInTaskbar = False. The app in task bar automaticaly disapear
so here's the code
Private Sub Main_SizeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.SizeChanged
'Si minimize, on met l'application en Systemtray
If Me.WindowState = FormWindowState.Minimized Then
TrayIcon.Visible = True
Me.Visible = False
End If
End Sub
Private Sub TrayIcon_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TrayIcon.Click
'Ouvre l'application main window si on click sur l'icon dans le tray
Me.Visible = True
Me.WindowState = FormWindowState.Normal
TrayIcon.Visible = False
End Sub
Enjoy

I'm trying to create a Windows Form that has a folder browser control on it, exactly like the VB.NET FolderBrowserDialog, but I also need to add some of my own custom controls onto the same form. So for this reason I can't just pop-up the FolderBrowserDialog - I need it present within my form.
But I can't find a way of adding the FolderBrowserDialog, or its individual components on to my form. Is this possible?
All I can find are controls like the DirListBox and DriveListBox, but I want to recreate the kind of browse dialog you'd see as standard in Windows, with buttons allowing the user to toggle View, Create New Folder, navigate back etc.
Thanks very much for any help,
Mark

No, it's not. But, you could create your own version of the dialog by inheriting from CommonDialog and adding the controls you want. To find out how the FolderBrowserDialog works, you can use .NET Reflector[^] to disassemble the code in the FolderBrowserDialog class and examine how that implementation works.
Now, with the standard FolderBrowserDialog, the user just has to right-click in the folder list to get the context menu and create a New/Folder, or you could just set the NewFolderButton property to True to tell the Dialog to display one itself. Navigate back is easy enough with the folder path dropdown list at the top of the dialog.
But, I don't know what you mean by "toggle view"? What view?

Is there any way to do it? if Yes?
please send me the 'logic' or 'steps'or 'code'
Thanks

You'll have to write your own installer or use a different package to build your installer, like Wise Installation System. The Package and Depoyment Wizard has no support for doing what you want.

I sure don't want to walk him through that! 
I've been through it once and didn't feel like doing it again. We had Wise for Windows Installer laying around, so I switched to that and got all the control I could ever want over the install.

When I close my application it disappears but when I look in TaskManager it is still there and I have to kill it manually. Why would that happen?

That can happen for any number of reasons. You have to be sure that you dispose all objects that hold open unmanaged resources. Make sure that if you're using any COM automation object, like Excel or Word, that it's closed and disposed of before you quit. Make sure all your threads are disposed of if they were not tagged as background threads when you created them. Make sure that you actually closed you main form instead of just hiding it... the list goes on and on.
Without knowing anything about your application or your code, it's impossible to tell you what went wrong.

Is a OleDbConnection an unmanaged resource? Not that it matters, I get an exception if I try to close one.

Yes, the OleDB classes wrap the underlying API for OleDB. If your code doesn't release these resources, then you will most likely have problems.
I saw you post in the C# Forum. We'll have to take a look at what you doing because you shouldn't be having problems closing that connection. Are you keeping a connection to the DB for the entire life of your app? The connection could be timing out and closing for you, leaving your resource pointers hanging and pointing to now invalid handles.

I have spent the last few days rewriting and rewriting parts of my code and still it happens. Is there any way to check what is causing this or it just finger in the stuff?

Without ever seeing any of your code, I can't tell you what's going on.
You might want to use a Profiler on your app for more information, like what objects are being allocated and released, or not released. Something like http://www.scitech.se/memprofiler/[^] would probably do the trick.

Thanks, I already tried that. Of course when run under that tool there isn't a problem and the application doesn't hang around in memory, the same as if I run it from the VS.NET IDE. I have tried everything I can think of and it won't go away. It only happens when I use the Xceed chart - Xceed say it is the first time they seen the problem and they can't replicate it. I really wanted to use their chart as it looks the best and has great features but it seems the gods are against me so I will have to use a different chart product.

How to check whether the internet connection is connected or not? I want to send email from my application, but it will raise problem if it's not connected.
Learning .NET

Checking for the connection to the internet is difficult because there is no way to know what is on the other side of your gateway address. You could have a live connection, but it might no be the internet.
The simplest way to do it is to try and resolve the DNS name of the mail server before you try to send a message.
Imports System.Net
.
.
.
Try
' Try and resolve the address of the mail server.
Dim hostEntry As IPHostEntry = Dns.GetHostByName(myMailServer.myISP.com)
' If we get here, then the DNS Resolve worked and
'we must be connected to the 'Net.
Try
' Code to send your email message...
Catch ex As Exception
' Send message failed for some reason...
End Try
Catch ex As Exception
' DNS Resolve failed. We can't send the message...
End Try

In my app I allow users to search text, and I'm trying to add a wildcard option. The users would supply both the string to be searched and the "search for" string, which can include wildcards * (0 or many characters), ? (single character), [] (character list), and [~] (character not in list). I've tried using the "like" operator, but it doesn't seem to work in all cases when I use more than two asterisks.
Seems to me this is a pretty standard feature that has probably already been written, but I seem to be looking in the wrong places. Can anyone point me to some code that does something similar to this? Maybe there's a regular expression someone has already written to convert a string with wildcards into a regex search?
Thanks

I'm using the VB.Net Data Form Wizard to create a data form to
show the information in my Access database. Trouble is, the Wizard
has a mind of it's own when it comes to the order in which it
shows the records in the database. I would like, for example, to
show the records in alphabetical order of people's names. Or, in
numerical order of something called a case number. But I see no way
to change the order that the Wizard created. In fact, I am unable to
tell what system the Wizard used to display the records. Maybe it is
in the same order that the records were added to the Access database.

We'd need to see the code the Wizard generated so we can see what your dealing with and how to modify it.

In case anyone is interested, I answered my own question after a couple
of additional days investigation. The answer is to change the SELECT
statement created by the Data Form Wizard in the Data Adapter. I added a
ORDER BY clause to the SELECT to put the records returned from the
database in alphabetical order by name. The SELECT statement now reads:
SELECT * from CASES ORDER BY compname.

I have hyperlink inside of my body, however whenever I launch outlook in the following way I don't have hyperlink but just simple text. I don't know if it is the function i am using for encoding or just shellexecute doesn't support.
strmail = "mailto:" & URLEncode(strEmailAddress) & "?Subject=" URLEncode(strsubject) & "&Body=" & URLEncode(strBody)
ShellExecute 0, "open", strmail , vbNull, vbNull, SW_SHOWNORMAL
Public Function URLEncode(URL As String) As String
Dim i As Long
For i = 1 To Len(URL)
Select Case Asc(UCase(Mid(URL, i, 1)))
Case Asc("A") To Asc("Z")
URLEncode = URLEncode & Mid(URL, i, 1)
Case Else
URLEncode = URLEncode & "%" & _
Right("00" & Hex(Asc(Mid(URL, i, 1))), 2)
End Select
Next
End Function
After the launching and see the source code I have <> converted to < and >. I think this is problem but i don't know how to fix this.

I have succesfully serialized and array of objects into an xml-file. But I haven't successed in doing the reverse, deserializing - reading the xml-file and put it back into an array.
---
Here is the class, simplified without properties:
<serializable()> Public Class Job
' main settings
Private strName As String
Private strDescription As String
Private strCmdLine As String
End Class Job
---
Here is my array declared along with a hashtable I use:
Public Jobs As New Hashtable
Public JobArray() As Job
---
Here is my serialize-function:
'Call BinarySerialize()
Dim myArray() As Job
ReDim myArray(Jobs.Count - 1)
Dim objStreamWriter As New StreamWriter("job.xml")
Dim x As New XmlSerializer(myArray.GetType)
Dim i As Integer
' looping through a datagrid and loading the array
For i = 0 To lVirtualTable.Rows.Count - 1
Dim j As Job = DirectCast(Jobs(lVirtualTable.Rows(i).Item(0)), Job)
myArray(i) = j
Next
Try
x.Serialize(objStreamWriter, myArray)
Catch e As Exception
MsgBox(e.Message.ToString)
End Try
objStreamWriter.Close()
---
The above function works and saves the xml-file correctly. I just need help with a function that fílls the array from the xml-file. Any ideas?
Thanks / Henrik

I have no idea what your doing wrong, because I can't test the code and play with it here at work.
But, you could try this article on MSDN first: Troubleshooting Common Problems with the XmlSerializer
