There is no equivelent object in Windows Forms. There is also no such thing as a login to a Windows Forms app unless you code in your own security system.

in vb sorting 2d array based on second column (urgent one plz)

peter rankel11-Jun-06 0:44

11-Jun-06 0:44

Hi, I've got a 2D array which I would like to sort into descending order according to the first column but keep the information in the 2nd column in the same row as the information in the first column no matter where the sort moves it to in the array. To explain more clearly:
Supposing I had this 2D array:

|5 1|
|6 2|
|3 3|
|8 4|
|2 5|

I want my bubble sort to be able to sort it into:

|8 4|
|6 2|
|5 1|
|3 3|
|2 5|

All the info I've found on bubble sorts has only been about 1D arrays. Any help or a nudge in the right direction would be really appreciated!
Thanks,

your

peter

Updating the WebBrowser document

grantg10-Jun-06 4:47

10-Jun-06 4:47

I want to make changes to the HTMLdocument that resides in a WebBrowser.Document

I can navigate to a web page,

WebBrowser1.Navigate(address)<br />

and the image looks good in WebBrowser1. After the document completes, I capture the event when a page element is clicked on:

Dim ClickedElement As HtmlElement<br />
   Private Sub Document_Click(ByVal sender As Object, ByVal e As HtmlElementEventArgs)<br />
       If (WebBrowser1.Document IsNot Nothing) Then<br />
           Dim pt As Point = System.Windows.Forms.Cursor.Position<br />
           pt = PointToClient(pt)<br />
           pt.Offset(-WebBrowser1.Left, -WebBrowser1.Top)<br />
           ClickedElement = WebBrowser1.Document.GetElementFromPoint(pt) 'WebBrowser1.Document.Window.Position)<br />
           ClickedElement.ScrollIntoView(True)<br />
           tblElements.Rows.Clear()<br />
           AddElementToTable(ClickedElement, 0, Direction.Ascending)<br />
           DataGridView1.DataSource = tblElements<br />
       End If<br />
   End Sub

Now I can do either of these:

'Change the ID of an element<br />
If clickedElementID = "" then ClickedElement.ID = "t_19"<br />

<br />
           'Add a new element after the one that was clicked<br />
           Dim newID As String = ClickedElement.Id & "_t1"<br />
           Dim newElement As HtmlElement = WebBrowser1.Document.CreateElement(newID)<br />
           newElement.Id = newID<br />
           ClickedElement.InsertAdjacentElement(HtmlElementInsertionOrientation.AfterEnd, newElement)

Both of these changes show up if I check the element:

For Each el As HtmlElement In ClickedElement.Parent.Children<br />
               Console.WriteLine("Sibling id: " & el.Id)<br />
           Next

Sibling id: t_19
Sibling id: t_19_t1

But I can't figure out how to have the display reflect the change or how to save the UPDATED version of the html. The WebBrowser1.documenttext doesn't reflect any changes.

Thanks!

Check with your system administrator whether you have an appropriate permission to write (save) to your file.

TCP/IP server

Does anyone have a good example of a TCP/IP server using the TCPListener and TCPClient classes in VB.Net 2005?

I need to write an application that listens for TCP/IP client connections. Once a client is connected the server must maintain these connections in order to process any incoming commands and to send out status information to the clients.

Any help would be appreciated.

Re: run application from the network drive

First you copy/install the application files onto the network drive.

Next, you must install all of your app's dependencies on to each client system that will run your app. This includes the .NET framework, MDAC (if you're using ADO.NET), any ActiveX or COM objects used, etc. If there are a lot of dependencies, then you might want to write a "Client Installer" for your app to simplify the process for your users.

What you need to use is called ADO.NET. It's a collection of .NET classes under the System.Data namespace which allow you to work with various databases. This is a big subject and I highly recommend that you read up on this on MSDN. See the below link.
You should also search this website and the Internet on this subject too. There's plenty of examples out there.

http://msdn.microsoft.com/library/en-us/cpguide/html/cpconoverviewofadonet.asp[^]

That said, you need to use the data provider classes under the System.Data.ODBC namespace. Read the above link to understand how to use them.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
