Yes. But the path would be like this "WinNT://DomainName/GroupName". I tried the following codes and I can see the GroupName there but I cannot see the members contain inside the group.
Dim DEntry As New DirectoryServices.DirectoryEntry("WinNT://DomainName")
Dim UserGrp As DirectoryServices.DirectoryEntry
For Each UserGrp In DEntry.Children
If UserGrp.Path = "WinNT://DomainName/GroupName" Then
MessageBox.Show(UserGrp.Path)
End If
Next
There, you can try it out. Again, many thanks, Ray.

I have created a windows service but how do you run the code in the IDE so you can step through and debug it?
|
|
|
|
|
You have to install it, start it then attach to it in the debugger. This will cause you to miss being able to really debug any code in the starting events.

What a pain! Do you know if you can have a System Tray Icon with a menu Associated with your service. I tried setting up a NotifyIcon, it runs through the code to set it up fine but it never appears in the system tray.

One trick I've been using is to put most of the initialization code in a one-shot timer (.AutoReset=False) and set the interval on that timer for something like 30-45 seconds. That gives you the time to connect the debugger to your service before that code starts.
Since my service is based around another timer, I just leave my main timer disabled until the initialization timer fires. Put your first breakpoint in the initialization timer and you can then debug that code.
Once you are happy with your initialization code, you can speed things up by changing the initialization timer's interval to something much shorter. Don't change the structure for production, just shorten the interval. If you need to re-debug something in the init code, you only have to change your interval again.

Two more questions.
1. How can I make my service handle the Pause and Continue events? I have the code for these events in my service (OnPause and OnContinue) but these selections are not available to me in the Service Manager. Also I wrote a custom app to control services, when I call the pause method against my service I get an exception because the service does not handle these events. (System.InvalidOperationException: Cannot pause Esanti_Core service on computer '.'. ---> System.ComponentModel.Win32Exception: The requested control is not valid for this service)
2. How can I write a service install function from a custom app?
|

|
|
Well I found the answer to my first question. You have to set the CanPauseAndContinue property in the InitializeComponet sub. i.e. Me.CanPauseAndContinue = true
|
|
|
|
|
The easier way of all (in my opinion) is to set up ASSERT and TRACE in your code.
Use the Debugview from www.sysinternal.com to trace your code but make sure your service is in debug mode.
Or use some debugging tool like softice and etc.

Hi.
I need some help. I'm trying to add user controls dynamically to a tabpage's controls collection. The problem is, once they've been added, i don't know how to listen for events raised within the user controls. Is there some control-object event handler?
HELLLP.
Thanks in advance.

Take a look in the help for addhandler. This should do the trick for you.

Events are handled in a good new way in .NET. When you want to listen to an event, you do this:
button.Click += new System.EventHandler(buttonClick)
where button.Click is the event, and buttonClick is a method with the correct arguments. When handling multiple controls' events, use the "Sender As Object" argument of the method you assigned to the event to find out which object fired the event.

How to check if file existe in VB?
Thanks for any reply.
|
|
|
|
|
Hi,
Just use "Dir" command in VB to check it's existance.
Say,
if Dir("filename") then
'' Task to do if file exists
end if
It will retrun True if exists or False if file is not there on the mentioned path. You can use other parameters like vbDirectory, vbSystemFile etc. to check file or folder property.

How about using the .NET framework WebRequest and Stream to read the data from the URL, then use a FileStream to write it out to a file?
There's and example of the read step on GotDotNet, http://samples.gotdotnet.com/quickstart/howto/doc/WebRequests/clientGET.aspx
And as for writing it to a file, the .NET library sample:

Hello all,
What are the date functions in VBA? I have a string in my Access 2000 code, and I'd like it to hold today's date. What do I call to get the date?
Dim theDate as string
theDate = date()
I know that is wrong, but what do I do?
Thanks
Nick

In VBA/MS Access Macro code, something like this should place today's date into a string:
Dim myDate As Date
Dim myDateString As String
myDate = Date
myDateString = CStr(myDate)
MsgBox myDateString
Hope that helps.

I have a Problem. I want get picture from a WebCam in a picturebox in VB.Net from a local computer. If anyone knows please write me at taj_saini@hotmail.com. Thanks

How does the WebCam stream data, via HTTP (or ...)? If so, suggest checking out the System.Net and System.IO classes & interfaces in the .NET framework.

Hello all,
I have what I hope is a quick question. In my Access 2000 database I have a Table called Candidates. In this table there is a Field called LName. How can I get the data in this field without opening the table?
This what I am trying to do. In the Main Form of my database, you can eneter a Last Name and hit the Command button and it will open the Candidate Table to the first occurence of the person with that last name. I'd like to write an autofill ability in the Main Form. This way when I type A into the space where you type in the last name, it will automatically fill the text to Aardvark for instance. And then if I hit another letter, like b and the string in there is "ab" it would return the first last name with Ab, for instance Aba.
Now, I know the logic behind how to do what I want, but I need the syntax.
How can I make a string equal the text in the last name field?
Would it be:
Dim lastName as String
lastName = [Candidate].[LName] ??
Any help you can offer me would be great.
And one more quick question.
Is there a way to access the characters in a string?
Can I type lastName[1] and get the first letter of the string?
Again thank you very much.
Nick

Aaaaaa you can't. You have to at least open it to run a querry on it and get the data out.
