That would be my guess too since I had to change some MSDTC settings on XP and Vista to get it to work.
Could the fact that the W2k PC in question is not on the same domain have something to do with it ?

More than likely. You'll have to read the links I posted.

Hi,
I am trying to build a VB.Net Application to logon to a web page, using Web Browser Comtrol.
Yes, I managed to get the web page loaded into the Web Browser Control. But I do not know how to
a. Find the first text box (which can accept data)
b. Pass on data - from a textbox in the form to that text box in web page
c. navigate to next control and so on.
There are combo's, check boxes, etc in the web page.
Can somebody please let me know how this can be achieved, and if there are any similar demos, that would be appreciated. Or is VB.Net itself a bad selection? I am new to all this.
Regards
Rajiv.

It's not the language that's the selection problem.
The WebBrowser control exposes the loaded document in its Document property as an HtmlDocument[^] object. You can use its methods and properties to find and manipulate the controls through that.

hi,
I'm using vb.net and I just want to ask about the do...loop until command.
I understand that this is used whenever we want to do a condition all over again until it is true.. But what if it comes out till the end as false? How will I put it into code..
in such way as:
Do <statement><br />
loop until <condition>
hope anyone can help me solve this out..
thanks..

I want to put another statement if the result of the looping is still false (after its process)
|
|
|
|

The do loop checks at the end of the run whether the condition is true. If it is true it terminates. If the condition is still false, it starts again at the "do". Maybe you want to add another condition like
do
...
loop until (condition1=true or condition2=true)
?
|
|
|
|
|
The Do While loop will run continuously until the condition is true. There is no alternate "end" of the loop. If that's a possibility, maybe you should be considering a different loop type, such as For/Next.

Thanks Dave..
I was thinking of that too as an alternative. But I just don't know what's that for and how to use it. i just saw it in the MSDN Support.

If you don't know what a For/Next loop is, you REALLY need to pick up a beginners book on VB.NET. A For/Next loop is one of those very basic concepts they teach on the second day of class in any course involving VB.

Im having issues using PrincipalPermission to authenticate a Windows Domain account. I need to be able to see if a user belongs to a domain group even if they are not the account currently logged into the workstation. Here is the scenario:
A set of users will belong to a group. It is called "group1" . I am attempting to run this code to check if they belong to this group. If so - let them continue. If not, then catch the error. Here is the problem. When I (myaccount) is logged into the machine it authenticates fine for me. It won't authenticate for someone who is a member of Group1 while I am logged into the machine. Even if the other user is a member of group1 and has Administrator rights such as "Otheraccount" does below. The workstation this is running on has the following in the Administrators group:
DOMAIN\myaccount
DOMAIN\otheraccount
DOMAIN\Group1 (myaccount and otheraccount are members of this group)
I am running this code:
'***********************************************************
Dim SecurityCheck As New PrincipalPermission("DOMAIN\"& strUserName, "DOMAIN\Group1")
Dim strError As String
Try
SecurityCheck.Demand()
Catch errormessage As System.Exception
strError = errormessage.Message
If strError = "Request for principal permission failed." Then
MsgBox("You are not a local administrator. You do not have rights to access this software. If you need access, please contact your manager.")
Me.Close
Exit sub
Else
msgbox(strError)
End If
'***********************************************************
Any suggestions? I have tried this as well with the same results:
Dim SecurityCheck As New PrincipalPermission("DOMAIN\"& strUserName, "Administrators")

Hi, I have an application that reads data from a text file into a datatable in the format required for a table in an SQL SErver 2005 database.
My question is, having filled the table 'manually' in memory, how do I connect that table to the database and insert the information? Obviously I can do inserts for each row in the datatable, but there are around 30,000 rows so I am looking for a faster method as this can take some time.
I understand that the dataadapter requires the insert command etc but 1) how do I get the table into the adapter and 2) does it know that these are new records?
Any help would be very geatly appreciated.

I wouldn't use a DataAdapter or DataTable. I'd just read the file and create the INSERT statements directly and push it through a SqlCommand object. You can put multiple commands into a SqlCommand object - It is just a string of SQL after all.

You may also want to checkout the SqlBulkCopy[^]class if you're using the .NET Framework 2.0 or above. Check to see if it'll fit your requirements first.

if (DateTime.Now > _dateToStopWorking) then Close()
Something like that will work fine.

thanks for the reply,
i already had the same idea, but we have to think about installation , if application is already installed at any time , it should not allow to install it again, (ie, uninstall current & then reinstall again)
how can block this..

One way is to hard code a date in your application and every time the application get's focus check on the date.
I used it once for a similar situation, but i did it with an encoded end date in the form of serial number. So my application decoded the serial number, that i saved in the Application's Properties and validated the date. If the date was passed, a msg box was shown and the application quited.
Hope that it gets you inspired, if someone else have nice ways, leave a reply.

I Known that there is an application called "IEActivityMonitor" can do this well and the source code is in "http://www.codeproject.com/useritems/IE_Activity_Monitor.asp"
However the source code is an old C# version. When I use Visual studio 2005, the source code is converted and do not work.
I hope someone can help me to write an VB version with the same functions.

In fact, if you put an IE control in your app, and handle it's events, the events will get fired for any instance of IE running on the PC. So, that's all you need to do.

Wow - is IE a static class then?
You always pass failure on the way to success.
