embed a office workstations map when everytime they log in. It will show the id name of that workstations or agent id...I'm trying to create an ActiveX Control connect to SQL server...

Since Windows doesn't track who logs in to what workstation and each Windows user can login, or I should say connect, to many Windows machines at the same time, this will be an inaccurate map.
But, for the most part, people only login to the workstation and attach to a few servers. You would have to have a component (Windows Service) running on every workstation to record login and logout events and what the user ID is. This service would have to report to a center server component that maintains a database of currently logged in users and what machine they're on. This is the easy part.
The hard part is showing the map and maintaining the datastore behind it. You'll need to write a small control that represents a workstation and displays its status, name and user ID that's logged in. There will also have to be a manager application that shows your map, creates and places controls for each workstation, and communicates with the central server to get each workstations status. The server could also log each change in status to another table in its database.
It would probably be a good idea to impliment a subscription service on the server that this manager application uses to get notifications of status changes from the server instead of the manager polling the server every some-odd seconds to get every workstation status. This is because logins/logouts don't occur often and constantly polling a server for things that don't change much is just a waste of resources and bandwidth.

I'm designing in VB 6.0 a program specifically intended to be placed on PDA's in the future. I think I need to use AppForge to make this easy but I haven't even installed AppForge on my PC yet, so maybe you AppForge users will know another approach to this... Anyway, I need some ideas on ways to implement an activation key or some sort of registration that will prohibit the end user of the software from being able to simply make a copy or 'beam' it to another PDA. I've got a EULA at the beginning which makes a registry entry if the user doesn't want to see it again (after he agrees to it first). Is there a simple solution there that I'm not thinking of?
Suggestions?
Thanks

Nope. Welcome to the world of copy protection. There is no easy solution to this at all. No matter what you, there will be a way around it.
You just have to make the copy protection so elaborate as to not make it obvious where the key is stored, either in the registry or diguised in a file somewhere.
The problem is, there are utilities out there that make it easy to trace what's going on in the File System and Registry.

The registry in not transferred over, but there's nothing stopping the user from just searching the Registry and exporting your key to a file, copying that over to the new PDA and importing it into the Registry.

Hello
I have a problem with the imagelist control, when the number of images it contains, becomes too much. I have a ListView control bound to it. The number of the items in the ListView (and thus, the ImageList) control, may become thounsands. But exactly when I have more than 1000 items in the ImageList, my program crashes: "This program has performed an illegal operation"
Is the problem exactly related to ImageList and putting too many images in that?
I really need your help.
Thanks

It doesn't look like there's a know problem like that. How are you loading up the ImageList?

It's in vb6.
It is in a function that gets FilePath and adds it's icon to the ImageList.
<br />
hIcon = ExtractAssociatedIcon(0, LCase(FilePath), 1)<br />
If IsNull(hIcon) Then<br />
'Error <br />
Else<br />
Set Pic.Picture = Nothing<br />
DrawIcon Pic.hdc, 0, 0, hIcon<br />
Pic.Picture = Pic.Image<br />
End If<br />
ImageList1.ListImages.Add , , Pic.Picture<br />
GetImageLisIconIndex = ImageList1.ListImages.Count<br />

I am trying to animate a .gif over a transparent background and have it working but the animation flickers. Can anyone help me? Here is my code if it helps:
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
InitializeComponent()
End Sub

If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
Private components As System.ComponentModel.IContainer
<system.diagnostics.debuggerstepthrough()> Private Sub InitializeComponent()
Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13)
Me.BackColor = System.Drawing.Color.LightGray
Me.ClientSize = New System.Drawing.Size(200, 184)
Me.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None

End Sub
#End Region
Private animatedImage As New Bitmap(Application.StartupPath() & "\..\dog.gif")
Private currentlyAnimating As Boolean = False
Public Sub AnimateImage()
If Not currentlyAnimating Then
ImageAnimator.Animate(animatedImage, New EventHandler _

currentlyAnimating = True
End If
End Sub
Private Sub OnFrameChanged(ByVal o As Object, ByVal e As EventArgs)
Me.Invalidate()

e.Graphics.DrawImage(animatedImage, New Point(0, 0))
End Sub
Public Shared Sub Main()
Application.Run(New Form1)
End Sub
End Class
Thanks for any help!

Try:
SetStyle(ControlStyles.DoubleBuffer | ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);
In your control's constructor.

In VB6 to centre a form I did the following....
Left = (Screen.Width - Width) / 2 ' Center form horizontally.
Top = (Screen.Height - Height) / 2 ' Center form vertically.
In VB.Net it does not like screen.height.
How can this be done in VB.Net

You can set the startup position in the properties window for the form as well.

Hi, I want to know how to check the current mouse position! Can someone help me with this?? Thanks! I am using vb.net! And when i click the left button i want to pop up a message box telling me where the mouse location is?
|
|
|
|
|
on mouse down/mouse up event of the form you will get the position in
e.X and e.Y
you have to Add the control.Left + if control inside any container then control.parent.left to ideally place the popup menu

What do I have to do so that I just need to do
Right(Text1.Text, 10)
rather than type
Microsoft.VisualBasic.Right(Text1.Text, 10)
|
|
|
|
|
strings.Right(Text1.Text, 10)
|
|
|
|
|
In a default VB.Net application you shouldn't have to do anything.
Microsoft.VisualBasic
is one of the default imports in the project template and
Right(str,len)
works, as is.
If it is not working you can
1) Include an Imports Microsoft.VisualBasic statement at the top of the file
2) Add Microsoft.VisualBasic as one of the imports in the project settings.
Project Properties/Common Properties/Imports
One caveat though, as mentioned, Microsoft.VisualBasic is included by default whenever you create project. If it is no longer there then someone must have explictly removed it and may have a good reason for this.
hth,
Alan.

I am trying to create a program that copy's one file to another at a certain time each day. Is there ant chance of some help or links to help?
Cheers

' append into the other file
Dim txt As IO.File
Dim fl As IO.StreamWriter
If txt.Exists("C:\abc.txt") = True Then
fl = txt.AppendText("C:\abc.txt")
fl.Write("testing")
' or open another file and read into it
fl.Close()
End If
' now if you want to copy the file from place to another then use
txt.copy(check parameters)
' for certain time put the timer control on the form to handle the time issue

I would suggest the following if I understand you correctly.
Function copyFile(ByVal sourceFileName As String)
Dim destFileName As String
If IO.File.Exists(sourcefilename) Then
IO.File.Copy(sourceFileName, destFileName)
End If
End Function
Pass the file name to copy into the function.
Use the OS event scheduler to handle when the program runs. This saves processor resources.
