[Q] WP7 - Removing an XElement from an XML file

Hi there,
I'm having a big issue, when trying to remove an XElement from an XML file created in IsolatedStorage.
--------------------------------------------------------------------------------------------
Code to CREATE the XML file
Dim File_to_Create As String = "Tracks.xml"
Dim file As XDocument = <?xml version="1.0" encoding="UTF-8"?>
<dataroot xmlnsd="urn:schemas-microsoft-comfficedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Cartridges.xsd" generated="2010-11-23T14:26:55">
<Carts>
<CART_NAME>First</CART_NAME>
<CART_COLOR>White</CART_COLOR>
</Carts>
<Carts>
<CART_NAME>Second</CART_NAME>
<CART_COLOR>Black</CART_COLOR>
</Carts>
</dataroot>
Dim isoStore As IsolatedStorageFile = IsolatedStorageFile.GetUserStoreForApplication()
Try
If isoStore.FileExists(File_to_Create) Then
MessageBox.Show(File_to_Create + " TRUE")
Else
MessageBox.Show(File_to_Create + " FALSE")
Dim oStream As New IsolatedStorageFileStream(File_to_Create, FileMode.Create, isoStore)
Dim writer As New StreamWriter(oStream)
writer.WriteLine(file)
writer.Close()
MessageBox.Show("OK")
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
'open selected file
Dim isoStream As IsolatedStorageFileStream
isoStream = New IsolatedStorageFileStream(File_to_Create, System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore)
Dim XML_File As XDocument = XDocument.Load(isoStream)
Dim Cart_Query As System.Collections.IEnumerable = From query In XML_File.Descendants("Carts") Order By _
CStr(query.Element("CART_NAME")) Descending, CStr(query.Element("CART_NAME"))
Select New Class_Cartridge_Data With {.Cart_Name = CStr(query.Element("CART_NAME")), _
.Cart_Color = CStr(query.Element("CART_COLOR"))}
Me.ListBox_Cartridges.ItemsSource = Cart_Query
isoStore.Dispose()
isoStream.Close()
End Try
--------------------------------------------------------------------------------------------
Code to ADD / EDIT XElement
Dim File_to_Create As String = "Tracks.xml"
Dim XML_IsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication()
' Check that the file exists if not create it
If Not (XML_IsolatedStorage.FileExists(File_to_Create)) Then
Return
End If
Dim XML_StreamReader As New StreamReader(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Read))
Dim XML_Document As XDocument = XDocument.Parse(XML_StreamReader.ReadToEnd())
XML_StreamReader.Close()
' Update the element if it exist or create it if it doesn't
Dim XML_XElement As XElement = XML_Document.Descendants("Carts").Where(Function(c) c.Element("CART_NAME").Value.Equals("First")).FirstOrDefault()
If XML_XElement IsNot Nothing Then
XML_XElement.SetElementValue("CART_NAME", "Third")
Else
' Add new
Dim newProgress As New XElement("Cartridges", New XElement("CART_NAME", "Fourth"), New XElement("CART_COLOR", "Blue"))
Dim rootNode As XElement = XML_Document.Root
rootNode.Add(newProgress)
End If
Using XML_StreamWriter As New StreamWriter(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Write))
XML_StreamWriter.Write(XML_Document.ToString())
XML_StreamWriter.Close()
End Using
--------------------------------------------------------------------------------------------
Now my issue and request for some help!
If I use
XML_XElement.Remove
then the following exception is raised whenever I try to "refresh" the bounded ListBox
System.Xml.XmlException was unhandled
LineNumber=37
LinePosition=12

In short, I can add or edit, but cannot DELETE an XElement...
Any ideas?
Thanks in advance!

Can you post the code you are using for XElement.Remove and use code tags so the formatting is right. Its the # button on the post toolbar.

Well, I did nothing special, just the XML_Element.remove, instead of adding a new xelement.
Then the error raises whenever I try to reopen the XML file.
My point is, how can I delete an specific xelement?
As far as I know, the following code should work
Code:
Dim XML_XElement As XElement = XML_Document.Descendants("Carts").Where(Function(c ) c.Element("CART_NAME").Value.Equals("First")).Firs tOrDefault()
If XML_XElement IsNot Nothing Then
XML_XElement.SetElementValue("CART_NAME", "Third")
Else
' remove the selected record
XML_XElement.Remove
End If
Honestly I don't know if the foregoing code is correct or if the issue is related to how WP7 handles the removal thus corrupting the original file.
Please let me know if you need anything else.
Any help is very appreciated!
PS: Thanks for the other replies, helped a lot!

Here's how I did it in c#. My xml file is very different than yours so the query will be different but the important parts are where you load and close the file streams and then write.
Code:
//Get users private store info
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
//open selected file
isoStream = new IsolatedStorageFileStream(list, System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument xml = XDocument.Load(isoStream);
isoStream.Close();
//Find section
XElement sectionElement = xml.Descendants("section").Where(c => c.Attribute("name").Value.Equals(groupn)).FirstOrDefault();
//Find item and remove it
sectionElement.Elements("setting").Where(c => c.Attribute("name").Value.Equals(litem)).FirstOrDefault().Remove();
isoStream.Close(); //Seems unnecessary but it's needed.
//Write xml file
isoStream = new IsolatedStorageFileStream(list, FileMode.Create, FileAccess.Write, isoStore);
xml.Save(isoStream);
isoStream.Close();

Thanks again for your help, greatly appreciated.
However I'm still getting the same error.
Sorry for asking, but are you getting any errors when deleting in WP7 ?
My knowledge on XML is extremely new and I'm sure that I'm making some mistakes somewhere...
But so far, I cannot get past the same exception.
Seems that the XML gots "corrupted" after the delete operation.
On the other hand, if is not too much to ask for, using my current code, how will handle the delete of the selected record?
Thanks!

I have no problem at all removing elements in c#. I don't have vb support even installed right now. If you think it's a bug you should post on the forums at http://forums.create.msdn.com/forums/98.aspx

Problem is my country is not listed so I cannot register...
Here is the C# version of my current code for adding/editing
Code:
public static void ADD_XML_Record()
{
string File_to_Create = "Tracks.xml";
var XML_IsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
// Check that the file exists if not create it
if (! (XML_IsolatedStorage.FileExists(File_to_Create)))
{
return;
}
StreamReader XML_StreamReader = new StreamReader(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Read));
XDocument XML_Document = XDocument.Parse(XML_StreamReader.ReadToEnd());
XML_StreamReader.Close();
// Update the element if it exist or create it if it doesn't
XElement XML_XElement = XML_Document.Descendants("Carts").Where((c) => c.Element["CART_NAME"].Value.Equals("dd")).FirstOrDefault();
if (XML_XElement != null)
{
XML_XElement.SetElementValue("CART_NAME", "bbbbb");
}
else
{
// Add new
XElement newProgress = new XElement("Carts", new XElement("CART_NAME", "dd"), new XElement("CART_COLOR", "ff"));
XElement rootNode = XML_Document.Root;
rootNode.Add(newProgress);
}
using (StreamWriter XML_StreamWriter = new StreamWriter(XML_IsolatedStorage.OpenFile(File_to_Create, FileMode.Open, FileAccess.Write)))
{
XML_StreamWriter.Write(XML_Document.ToString());
XML_StreamWriter.Close();
}
}
I tried your code but I'm having a bad time making it to work.
If not a big deal, please could you tell me how to modify it ?
I mean, if a record is found, instead of editing, to remove it?
Honestly I'm stuck and any help is more than apprecisted!

So you haven't seen anything lol
Go to the right corner at the bottom, then go to settings and the power bottom will be right there. Most apps has settings and everytime you go there, different settings will be shown for the specific app :fingers-crossed:

Can you guide how to save as .vbf file. I don't know how to apply your script. Please guide me as I'm a noob.
Thanks in advance, bro.
PS: I'm using window 8 with notebook.

[Tutorial] How to simply get TRACE output from native dll to managed VS2010 debugger

Hi friends.
There is simple tutorial. We use WP7 DllIprort Project, or another native Dlls, to enable our managed (mostly Silverlight) applications to do any system calling. But, debuging of hybrid applications is difficult. May be, somebody is able to make publicly usable source to use standard Visual Studio way to test and debug native Dlls, but Ultrashot and others have no time, they have important things to do.
Then, I prepared simple library, which export native TRACE macro and managed wrapper too.
Using:
1. Copy all content from attachment NativeDebugTraceVS2008 directory to your VS2008 native dll project directory.
2. Add NativeDebug2008.dll and NativeDebugTrace.h to your native dll project.
3. Add line:
#include "NativeDebugTrace.h"
on top of your native c++ source code.
4. Use TRACE macro in your code. Syntax is usual, example:
...
int nVal = 1+1;
TRACE(L"%s = %d", L"nVal", nVal);
...
Output is showed in "normal" VS2008 Output window too, when you debug under VS2008.
If you have used another TRACE macro in your code, you can rename TRACE macro to ANY_OTHER_TRACE_NAME in NativeDebugTrace.h and call this another macro.
5. Copy all content from attachment NativeDebugTraceVS2010 directory to your VS2010 managed application or dll project directory.
6. Add both NativeDebug2010.dll and NativeDebug2008.dll to your project, set Copy if newer its option.
7. Add reference to NativeDebug2010.dll to your project.
8. Add Initialisation to your App constructor:
Code:
...
public App()
{
...
// Show graphics profiling information while debugging.
if (System.Diagnostics.Debugger.IsAttached)
{
...
NativeDebug.Init();
}
else
{
NativeDebug.RegisterOnly();
}
}
...
I am not sure why, but RegisterOnly() calling is necessary to work without debugging, your native dll will not load properly instead.
9. Add garbage release to your App closing:
Code:
...
private void Application_Closing(object sender, ClosingEventArgs e)
{
NativeDebug.Destroy();
...
}
...
10. Change your VS2010 view to Expert (Menu/Tools/Settings/Expert Settings).
11. Open your Output window on top (Menu/View/Output, click to Window Position/Float).
Now you can see all managed System.Diagnostics.Debug.WriteLine and native TRACE ouput in one Output window. Attention - option "Menu/Tools/Options/Debugging/Redirect all Output text to Immediate window" does not work for me.
You can also write output to TRACE file by standard way (see System.Diagnostics.Debug.WriteLine help).
Attention: Debug Trace Library is fully synchronised, but I did not test it to debug more then one application alternately. May be any deadlock can occure, but I beleive will not. When your managed code use another unicode string prefix then L"...", try to change calling, and write your experience here.
See example picture, follow red text:

Picture is from old version, included to W.I.N.C.O native library. But, yestarday I have got total hard disc crash crying::crying::crying, all my programs from long time are lost. I must programm this feature again today, I believe it is better then last weak.
Note:
Attachment is functional, but will be changed in future. Little COM mishmash and WP7 WatchDog problems occured.
Next code probably solve it, but I am not sure. Do not forget to set HKLM\Software\Microsoft\TaskHost\DehydrateOnPause to 0 first, when you want to debug application calling ShellExecuteEx() etc.
Code:
private void Application_Activated(object sender, ActivatedEventArgs e)
{
NativeDebug.Start();
}
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
NativeDebug.Stop();
}

TRACE Output example. MFC integrated to ATL for WP7, registry export to file.
This is output from registry exporting wiht MFC using. Without tracing it woud be very difficult to tune to a flawless running:

What does php mean?
php is a self-referentially acronym for PHP: Hypertext Preprocessor. Original it supposedly meant personal home page. It is an open source, server-side, HTML embedded scripting language used to create dynamic Web pages. In an HTML document, PHP script (similar syntax to that of Perl or C ) is enclosed within special PHP tags. Because PHP is embedded within tags, the author can jump between HTML and PHP (similar to ASP and Cold Fusion) instead of having to rely on heavy amounts of code to output HTML. And, because PHP is executed on the server, the client cannot view the PHP code. PHP can perform any task that any CGI program can do, but its strength lies in its compatibility with many types of databases. Also, PHP can talk across networks using IMAP, SNMP, NNTP, POP3, or HTTP. PHP was created sometime in 1994 by Rasmus Lerdorf. During mid 1997, PHP development entered the hands of other contributors. Two of them, Zeev Suraski and Andi Gutmans, rewrote the parser from scratch to create PHP version 3 (PHP3).
In simple words >>>
PHP is a scripting language which is highly powerful open source that's widely used for web development activities to create efficient and dynamic web pages. PHP programming is specialty of Arth InfoSoft, we have developed various industry based websites like realtors, financial, engineering, social networking, hotel and hospitality, B2B, Shopping and many more.
No let's learn [ PHP Login script ] : :cyclops:​
Learn to create a simple login system with php + mysql script, this tutorial is easy to follow, teach you step by step.
Overview​
In this tutorial, we create 3 php files for testing our code.
1. main_login.php
2. checklogin.php
3. login_success.php
Steps
1. Create table "members" in database "test".
2. Create file main_login.php.
3. Create file checklogin.php.
4. Create file login_success.php.
5. Create file logout.php

Click to collapse
STEP1: Create table "members"
For testing this code, we need to create database "test" and create table "members".
CREATE TABLE `members` (
`id` int(4) NOT NULL auto_increment,
`username` varchar(65) NOT NULL default '',
`password` varchar(65) NOT NULL default '',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=2 ;
--
-- Dumping data for table `members`
--
INSERT INTO `members` VALUES (1, 'john', '1234');
Click to expand...
Click to collapse
STEP2: Create file main_login.php
The first file we need to create is "main_login.php" which is a login form
############### Code
<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form name="form1" method="post" action="checklogin.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Member Login </strong></td>
</tr>
<tr>
<td width="78">Username</td>
<td width="6">:</td>
<td width="294"><input name="myusername" type="text" id="myusername"></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name="mypassword" type="text" id="mypassword"></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td><input type="submit" name="Submit" value="Login"></td>
</tr>
</table>
</td>
</form>
</tr>
</table>
Click to expand...
Click to collapse
STEP3: Create file checklogin.php
We have a login form in step 2, when a user submit their username and password, PHP code in checklogin.php will check that this user exist in our database or not.
If user has the right username and password, then the code will register username and password in the session and redirect to "login_success.php". If username or password is wrong the system will show "Wrong Username or Password".
############### Code
<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="members"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>
Click to expand...
Click to collapse
STEP4: Create file login_success.php
User can't view this page if the session is not registered.
############### Code
// Check if session is not registered, redirect back to main page.
// Put this code in first line of web page.
<?php
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>
<html>
<body>
Login Successful
</body>
</html>
Click to expand...
Click to collapse
STEP5: Create file Logout.php
If you want to logout, create this file. The code in this file will destroy the
// Put this code in first line of web page.
<?php
session_start();
session_destroy();
?>

Good tuto.
I just have one question : Why not use PDO ? Since the goal is security, won't it be more efficient ?

near the end it mentions encrypting the password but doesn't say how you are doing it.
(guessing its javascript - maybe using a library to do AES encryption or possibly just sending a hash of the password instead?)
.
maybe the encryption stuff was truncated by a length limit on posts?
