Hello,

[VS 2005]

I have created a user control that has a tab control, text boxes, combo boxes. I have a typed dataset with some datatables and tableAdapters for doing the inserts and the delete, and updates.

I build the control and when I want to use this control in another project.
1) open a new windows form project
2) Create a new tab on the tool box
3) Choose items
4) Browse to the dll in the release folder.

My question when I add the dll it also adds the typed dataset, table adapters. I have done something wrong as I think it should be the control itself and not the table adapters and the dataset. As when I click ok with the above selected it add them to my toolbox.

Can anyone explain about this, and if I have done done something wrong.

Many thanks for your help,

Steve

How to get all objects or controls in a form?

Every form has a Controls collection. This is where you'll find all the controls on the form. There's a little bit of a "gotcha" though. Controls can have Control collections of their own, so you can end up having controls inside other controls, like RadioButtons in a GroupBox or Panel.

You can enumerate the controls like this:

For Each c As Control In Me.Controls
    If TypeOf c Is Panel Then
        Dim tb As Panel = DirectCast(c, Panel)
        ' do whatever you want with the Panel you found
    End If
Next

Is there anyway or component (especially free) which creates password protected zip files.

Thanks.

Try with this Code.

Dim ZipFile As ChilkatZip2<br />
<br />
Private Sub Command1_Click()<br />
    <br />
    ' Get the zip file name<br />
    CommonDialog1.ShowOpen<br />
    CommonDialog1.CancelError = True<br />
    SourceFile.Text = CommonDialog1.FileName<br />
     <br />
End Sub<br />
<br />
Private Sub Command2_Click()<br />
    <br />
    ' Create a ChilkatZip object<br />
    Set ZipFile = New ChilkatZip2<br />
    ZipFile.UnlockComponent UnlockCode.Text<br />
    ZipFile.NewZip OutputZip.Text<br />
    <br />
    ' To create a WinZip-compatible password-protected Zip, simply<br />
    ' set the PasswordProtect property to 1, and set a password.<br />
    ' To unzip, WinZip will prompt for this password.<br />
    ZipFile.PasswordProtect = 1<br />
    ZipFile.SetPassword "secret"<br />
    <br />
    ' Add the disk file to the Zip object<br />
    ZipFile.AppendFiles SourceFile.Text, 0<br />
    <br />
    ' See if anything was added.<br />
    If (ZipFile.NumEntries = 0) Then<br />
        ZipStatus.Caption = "Error, no files added to the Zip archive."<br />
        Set ZipFile = Nothing<br />
        Exit Sub<br />
    End If<br />
    <br />
    ' Compress and write to disk.<br />
    success = ZipFile.WriteZip()<br />
    If (success = 0) Then<br />
        MsgBox ZipFile.LastErrorText<br />
        Exit Sub<br />
    End If<br />
<br />
    ' How much compression occured?<br />
    Dim e As ChilkatZipEntry2<br />
    Set e = ZipFile.GetEntryByIndex(0)<br />
    If (Not (e Is Nothing)) Then<br />
        origSize = e.UncompressedLength<br />
        compressedSize = e.CompressedLength<br />
        ZipStatus.Caption = "Success." + vbCrLf + Str(origSize) + " bytes compressed to " + Str(compressedSize) + " bytes"<br />
        Set e = Nothing<br />
    End If<br />
    <br />
    ZipFile.CloseZip<br />
    <br />
    Set ZipFile = Nothing<br />
    <br />
End Sub<br />
<br />
Private Sub Form_Load()<br />
    OutputZip.Text = CurDir$ + "\outputFile.zip"<br />
    <br />
End Sub<br />

The code is nice and all, but where's he going to get the ChilkatZip2 class library from?

You can use the #ZipLib to do this. Find it here[^].

You'll have to create a custom label control for this, easily done by inheriting from the existing Label class. You'll need to add a Timer to your control, and a couple of properties and methods so you can set the blink rate and start and stop the blinking. Then it's just a matter of making the foreground color match the background color and changing it back to what it's supposed to be on every timer tick.

Use a timer to set the Visible property of the label to either true or false.

operating system accounts(to login) in vb.net

I am using the following code to list the accounts of my operating system.
Currently i have just two accounts namely
1.Administator
2.Guest
But it shows 6 accounts.
can i filter the query to make it to show the actual accounts.

Dim oQuery As New Management.ObjectQuery("select * from <br />
 Win32_Account WHERE SIDType = 1")<br />
         Dim osearch As New ManagementObjectSearcher(oQuery)<br />
         Dim ocollection As ManagementObjectCollection = osearch.Get<br />
         Dim oresult As ManagementObject<br />
         For Each oresult In ocollection<br />
             TextBox1.Text = oresult("Name").ToString & " "<br />
         Next

Thank You
Pankaj

I think it is showing the real accounts, with the `hidden` accounts, such as the help and support account, if you have VMWare installed, __vmware_user__ and other things.
You could try:

For Each oresult In ocollection
Dim oname As String = oresult("Name").ToString
If Not oname.StartsWith("SUPPORT") Then
   If oname <> "__vmware_user__" Then
      If oname <> "ASPNET" Then
          If oname <> "HelpAssistant" Then
              textBox1.Text = oname & " "
          End If
       End If
   End If
End If

I don't know if this'll work very well.

No idea. I've never used FoxPro and, most likely, never will. I would assume that it would take a re-write of the entire database.

Sure. You'd use the OleDb database objects, just like you would with an Access database. YOu can find the correct connection strings here[^] at ConnectionStrings.com.

No, you should write your app to behave this way, not try to make it work this way, after it is written.

Did you try google ?

You could tell the installer to execute your program after the installation has finished.

HI there,
so what's the logic to tell the Installer.... , to do a particular thing, before the complition of the installation.
I mean can i put my poject exe into the System Configuation Utility/StartUp
programatically , before the complition of the installation.
Thanks You.
