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 />
or
<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.

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.

How do I setup project written in vb.net 2003, so application could be ran 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.

actuualy i have worked on oledb but not on ODBC. i have read a example in it they use ADODB but when i use it in my code it gives me error. there is no namespace of this name how i can use it plz tell me

That's the old ADO library used by VB6 and older versions.
To use ADO.NET, you need to add a reference to the System.Data.dll in your project. In Visual Studio 2003, you can do this by right clicking on your project's References folder, select Add References, select System.Data.dll in the listbox, click Select, and then click OK. This will give you access to the System.Data namespace and all of its classes. You'll need to use the System.Data.Odbc.OdbcConnection class to connect to the database. The below link to MSDN will show you a quick example on how to use this class.
http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemDataOdbcOdbcConnectionClassTopic.asp[^]
I hope this helps!

Is there any particular reason why you are using an ODBC provider and not the SQL Server provider in ADO.NET?
Anyway, this code:
OdbcCmd.CommandText = "Call AddMember(?, ?, ?, ?)"
OdbcCmd.CommandType = CommandType.StoredProcedure Appears to be causing the problem. If you use the CommandType.StoredProcedure then the CommandText should contain the name of the stored procedure and nothing more.

Thanks for the reply. I'm new to VB so I haven't seen anything that says to use one or the other and why. I tried your suggestion and I'm still getting an error. Here are the results when I just provice the procedure name:
MSSQLJOB 964-9a4 EXIT SQLExecDirectW with return code -1 (SQL_ERROR)
HSTMT 03A31BC0
WCHAR * 0x010C08E8 [ -3] "AddMember\ 0"
SDWORD -3

You didn't answer my previous question: Is there any particular reason why you are using an ODBC provider and not the SQL Server provider in ADO.NET?
If there is a specific provider for your database in .NET (and for SQL Server there is) then use the classes of that provider rather than use ODBC. Use SqlCommand, SqlConnection and so on rather than OdbcCommand, OdbcConnection and so on unless you have a very compelling reason to use the ODBC provider.

I have my base form which has background image , tool bar etc,All other
forms inherit it. The background image size is 34kb and it is in Jpeg
format.All the other forms also has many images since we have unique look and
feel. The issue I am facing is performance .
Application works fast when I don't have background image on my base form (
in turn we don't have any background image for any of the form), But when I
apply background image for the base form or individual form , screen loads
slowly ie.. the controls on the screen loads slowly .
is there any way to overcome this problem

Is there a way of getting the length of a string in pixels based on the current font so you can change the size of a label to fit the text in exactly like the MessageBox.
I'm trying to create my own dialog box that pops up with a user entered message at a specific time. I dont want to limit the user to a certain character length.
Many thanks

I use this method to adjust the font size so my strings fit in the available width.
Dim ThisFont As Font = AdjustFontSize("Steve", 40, New Font(Me.Font.Name, Me.Font.SizeInPoints, Me.Font.Style))<br />
<br />
<br />
Public Function AdjustFontSize(ByVal s As String, ByVal w As Integer, ByVal LocalFont As Font) As Font<br />
Dim Gr As Graphics = Me.CreateGraphics<br />
Dim ThisFontSize As Single = 15.0!<br />
<br />
Do<br />
ThisFontSize -= 0.5!<br />
LocalFont = New System.Drawing.Font(LocalFont.Name, ThisFontSize, LocalFont.Style)<br />
Loop While (Gr.MeasureString(s, LocalFont).ToSize.Width > w) AndAlso (ThisFontSize > 7.5!)<br />
<br />
Gr.Dispose()<br />
Return LocalFont<br />
<br />
End Function<br />

Thanks for that. Looks like I can use the MeasureString method to get the results I want.
