Here is the most simple way to read and write an xml file with attributes and values.

For the sake of this example let's say we have an application that on form load creates toolstrip butons that when cliked load a web page on a web browser

First of all let's see the format of the Xml file

How do you programatically open a file in c# to append?

I tried searching online for an example and so far I have not found anything.

There is System.IO.StreamWriter and there is System.IO.StreamReader but there is no StreamAppend. Is there some way to use StreamWriter without overwritting the content of the existing file? Is there some way to use System.IO.Stream with some sort of appending criteria?

Hi was wondering if you have any source code on displaying a users profile in the twittervb2 api followed your tut and have developed it.

Good evening all,

I need some help. I'm trying to query my MySQL database to see if the currently logged on user to my application has certain rights/role. If the queried value does exist, then I want to enable a certain menu item.

Your help would be greatly appreciated.

Here's my code - what am I not doing right?:

[code2=vbnet]Public Sub checkAccessLevel()
Dim dbConn As New MySqlConnection(String.Format("Server={0};Port={1};Uid={2};Password={3};Database=parts", FormLogin.ComboBoxServerIP.SelectedItem, My.Settings.DB_Port, My.Settings.DB_UserID, My.Settings.DB_Password))
Dim dbQuery As String = "SELECT Level = 'Admin' FROM users WHERE username = '" & FormLogin.TextBoxUsername.Text & "'"
Dim dbAdapter As New MySqlDataAdapter(dbQuery, dbConn)
Dim dbData As MySqlDataReader

Try
dbConn.Open()
dbData = dbAdapter.SelectCommand.ExecuteReader
If dbData.HasRows() = True Then
TSMenuItemOptions.Enabled = True
Me.Refresh()
Else
TSMenuItemOptions.Enabled = False
End If
dbData.Close()

Catch ex As Exception
MessageBox.Show("A DATABASE ERROR HAS OCCURED" & vbCrLf & vbCrLf & ex.Message & vbCrLf & _
vbCrLf + "Please report this to the IT/Systems Helpdesk at Ext 131.")
End Try
dbAdapter.Dispose()
dbConn.Close()
End Sub[/code2]

I was wondering if anyone had any videos on how to change the settings on Windows 7 to boot from a USB drive and how to change It back to boot to my regular Windows 7 in case I decide I don't like Ubuntu? I'm fairly new to Linux so any other tutorials on it would be appreciated, too

I am not a master at the VB language. I am fairly new to actually trying to learn the language. I am writing a program, that requires that needs to do the following things:

* Read the XML document
* Create a ToolStripButton for each childnode in the XMLDocument with the text <name>
* Add handlers tI each button created that, when clicked, will navigate a web browser to the text in one of the other childnodes <URL>
* Change other properties according to diffrent buttons to diffrent child nodes.

I might have child nodes wrong, I'm not a master at XML documents.

But if you need to see the code I previously tried, I'll have to get on my computer when I get home.

I know how to do it in c#, but how would I do it in vb?

I might not have posted this in the right place...

But I have a program (I might share it later) and want to post it on Codeplex. I have a page for it, have my first release uploaded, everything BUT uploaded source code.

I'm not too thrilled to HAVE to do this, but when I go to, I can't find an upload source button

How do I do this or how do I get around uploading it period?

Can some one help me with the script like this. I want the script of referring and unlock the link and redirect to next page or something like that.
