I have 2 textboxes. When I click submit, i want to add whatevers in the text
box1 as username and whatevers in textbox2 as userid into an xml file. How do
I do that in ASP.NET using vb.net?
My xml file look like this:
<?xml version="1.0" encoding="utf-8" ?>
<!-- format is <user>userid</user> -->
<userdata>
<user name="Username1 ">
<userid>abc1</userid>
</user>
</userdata> 9 1745
Just construct a string as follows:
Dim myXml As String = "<?xml version="1.0" encoding="utf-8" ?>" &
ControlChars.Cr Lf _
& "<!-- format is <user>userid</user> -->" & ControlChars.Cr Lf _
& "<userdata> " & ControlChars.Cr Lf _
& ControlChars.Ta b & "<user name=" & ControlChars.Qu ote & textBox1.Text
& ControlChart.Qu ote & ">" & ControlChars.Cr Lf _
& ControlChars.Ta b & ControlChars.Ta b & "<userid>" & textBox2.Text &
"</userid>" & ControlChars.Cr Lf _
& ControlChars.Ta b & "</user>" & ControlChars.Cr Lf _
& "</userdata>"
Or you could omit the tabs and carriage returns as they are ingnored by xml
parser anyhow.
Alternatively, you could create an XML document and use .Net XML library to
add nodes into it and then save the result into a file (string or stream)...

Not sure what are your rules to pick a file, but if you need to update an
existing xml file you could use something similar to the following:
Dim xmlDoc As XmlDocument = New XmlDocument()
xmlDoc.Load(fil eName)
Dim xPath As String = ""//user[@name='" & textBox1.Text & "']"
Dim root As XmlNode = xmlDoc.Document Element
Dim node As XmlNode = root.SelectSing leNode(xPath)
If node Is Nothing Then
node = xmlDoc.CreateEl ement("user")
node.Attributes .Add(node.Creat eAttribute("nam e", textBox1.Text))
' add userid node to user here
...
' now add created node to the document
root.ChildNodes .Add(node)
Else
' update the existing node
node.SelectSing leNode("./userid").Value = textBox2.Text
End If
xmlDoc.Save(fil eName)
I am not sure about the syntax, as I do not have VS in front of me - but you
can check the help if something does not compile...
And do not forget to wrap the whole thing into Try..Catch block

The following code should compile just fine (provided that you have textBox1
and textBox2 TextBoxes on your form):
Try

I tried this code, it compiles without any errors. I run it without any
errors, but it doesn't create a file called myfile.xml.

Rocky,
If you put a breakpoint to the line inside Catch block i wold say that you
should see an error similar to "File not found", and this error must be
generated by
xmlDoc.Load(fil eName) line.
The code I used assumed that you already have a valid xml file, rather than
create one from within the application.

hi all
am updating the same file in ftp, through multiple clients, but am
scared that two clients may open the same file at a time, and try

can i lock it, if one client opens it for updating, so that till it
gets relased it cannot be updated by other clients.
Could u please suggest me the simple solutions...

The application we are developing uses MS Access 2003 database (with
help of ADO).
We have noticed that during massive records updating the size of the
mdb file increases dramatically (from 3-4 to 200-300 Mb).
After compacting the file shrinks back to 3-4 Mb.
I have performed the following experiment. I created a test database
containing only one table with two columns (Key number, Value
text(50)).
The table contains 10 thousands...

My application is calculation intensive and the servers are agonizingly slow.
Administrators of my application only update the backends once a month (twice
a month max). So, my launching program allows the back-end file to be
downloaded to the user's PC. This will provide maximum speed for these
calculations/manipulations of data. Without this, just logging into the main
app connected to the server back-end file can take five minutes...

I'm guessing this is a laughably obvious answer to many here, but it's
not to me (and I don't have a server or any knowledge of PHP to be able
to try it). It's not strictly a PHP question, but something that PHP
guys would know the answer to. I can't think of a more appropriate forum
to try. I've heard the ASP and JSP guys aren't as friendly ;-)
Let's say we have a HTML page from domain example.com, and that HTML
page makes a request to...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
