writeXML(fullFilePath) DOESN'T Write

[Guest]

I'm trying to write a DataSet back out to the same location it reads in from with readXML(fullFilePath), just to a different filename. The program breezes right on through with no exceptions, but the file just isn't there!

There's data in the DataSet and I have write rights to the fullFilePath specified.

What could be happening and how do I get around it?

Art,

I could not think if anything, you're the first one with this problem.
Many developers are confused with relative paths which are not supported on
CE, so file in a wrong location is pretty common.
But no file at all and no exception... That's something new.

Could you try this for me? You can check for file "foo.xml" in root folder
with file explorer as soon as you run this app and click on a button...
Please let me know if file was saved.

using System;
using System.Drawing;
using System.Collections;
using System.Windows.Forms;
using System.Data;

namespace WriteXML
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.MainMenu mainMenu1;

public Form1()
{
//

//
InitializeComponent();

//
// TODO: Add any constructor code after InitializeComponent call
//
}
/// <summary>
/// Clean up any resources being used.

protected override void Dispose( bool disposing )
{

}
#region Windows Form Designer generated code

private void InitializeComponent()
{
this.mainMenu1 = new System.Windows.Forms.MainMenu();
this.button1 = new System.Windows.Forms.Button();
//

//
this.button1.Location = new System.Drawing.Point(88, 72);
this.button1.Text = "Write!";
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// Form1
//
this.Controls.Add(this.button1);
this.Menu = this.mainMenu1;
this.Text = "Form1";

}
#endregion

/// <summary>
/// The main entry point for the application.
/// </summary>

static void Main()
{
Application.Run(new Form1());
}

private void button1_Click(object sender, System.EventArgs e)
{
DataSet ds = new DataSet();
ds.WriteXml("\\Foo.xml");
}
}
}

Will give it a try on my development machine at work tomorrow. I'm writing in VB, but I think I can do the conversion from C.

Thanks.

I'm trying to write a DataSet back out to the same location it reads in

from with readXML(fullFilePath), just to a different filename. The program

[Ilya Tumanov [MS]]

The next step I would take is hard resetting the device and reinstalling CF.



But before you do that, could you please try that modification to your test:

Dim ds As DataSet = New DataSet

ds.WriteXml("\Foo.xml")
MsgBox("Just executed the WriteXML command")

Dim anotherDs = New DataSet

anotherDs.ReadXml ("\Foo.xml")

MsgBox("Just executed the ReadXML command")




I wonder if you'll get FileNotFound exception and/or if you'll see messages.

Will give it a try on my development machine at work tomorrow. I'm
writing in VB, but I think I can do the conversion from C.

Thanks.

Art,

I could not think if anything, you're the first one with this problem.
Many developers are confused with relative paths which are not
supported on
CE, so file in a wrong location is pretty common.
But no file at all and no exception... That's something new.

Could you try this for me? You can check for file "foo.xml" in root
folder
with file explorer as soon as you run this app and click on a button...
Please let me know if file was saved.

using System;
using System.Drawing;
using System.Collections;
using System.Windows.Forms;
using System.Data;

namespace WriteXML
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1;
private System.Windows.Forms.MainMenu mainMenu1;

public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();

//
// TODO: Add any constructor code after InitializeComponent call
//
}
/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
base.Dispose( disposing );
}
#region Windows Form Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.mainMenu1 = new System.Windows.Forms.MainMenu();
this.button1 = new System.Windows.Forms.Button();
//
// button1
//
this.button1.Location = new System.Drawing.Point(88, 72);
this.button1.Text = "Write!";
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// Form1
//
this.Controls.Add(this.button1);
this.Menu = this.mainMenu1;
this.Text = "Form1";

}
#endregion

/// <summary>
/// The main entry point for the application.
/// </summary>

static void Main()
{
Application.Run(new Form1());
}

private void button1_Click(object sender, System.EventArgs e)
{
DataSet ds = new DataSet();
ds.WriteXml("\\Foo.xml");
}
}
}

I'm trying to write a DataSet back out to the same location it reads
in
from with readXML(fullFilePath), just to a different filename. The
program
breezes right on through with no exceptions, but the file just isn't
there!

There's data in the DataSet and I have write rights to the
fullFilePath
specified.

What could be happening and how do I get around it?

 

[Guest]

Won't be able to try it till Tuesday, but it's a good idea. My bet is that I'll get a FileNotFound exception.

So far, this app is running on an emulator, so everytime I start it cold (with the emulator closed), it's loading everything fresh. There's just something I'm missing...

Wait a minute... Are you doing this on a Windows CE device or on the
desktop? If on the device, what Write Rights are you talking about? Windows
CE does not have filesystem permissions. Or perhaps you expect to find the
dataset xml written by the code on the device in your PC filesystem?

Right now it's running on a Windows CE emulator and reading its input XML into the dataset from the path noted in the code I've provided (using variable sPath). I'm simply trying to write the XML back out to the same path using the ds.writeXML(fullPath) command.

The only reason rights are being mentioned at all is because we're trying to figure out why the XML is not getting written back out. If I use one of the sample code pieces from the VB .NET Resource Kit ("How To Write An Offline Application") that runs under the full .NET Framework, it works great, but when I move down into the Compact Framework, it won't write.

To reiterate, it throws no exceptions, but the file just isn't there --- anywhere --- when I look.

I thought I might have the answer when I saw this in the emulator's Help file:

The following hardware and drivers are not supported in the Emulator:

Universal serial bus (USB) devices

PC Card devices

Storage devices, which include compact flash (CF) cards and hard disks

File system drivers, which include file allocation table (FAT), compact disc (CD), and digital video disc (DVD) drivers

IEEE 1394 devices

But when I had a couple of programmers at our corporate headquarters try on both a Windows CE and Pocket PC emulator, it worked for them.

What am I missing?

Sorry, I meant to tell you...

When I tried your suggestion of immediately creating another dataset and trying to read the file just "created", as in:

Dim ds As DataSet = New DataSet

ds.WriteXml("\Foo.xml")
MsgBox("Just executed the WriteXML command")
Dim anotherDs = New DataSet

anotherDs.ReadXml ("\Foo.xml")

MsgBox("Just executed the ReadXML command")

it executes with no exceptions --- and no file. I've looked for the file at all levels of the directory from which the app is running, both manually and via Search. I already know where the app is READING the XML file from and, since the path I give the writeXML function is exactly the same, it seems the file should be there. If it is, though, it's invisible.

As posted earlier, a programmer at our corporate office tried to write XML within both Windows CE and Pocket PC emulators and it worked. This is a very frustrating mystery...

I'd say that's a concrete proof the file is saved.
Should file not be saved, you would get FileNotFound exception which you
had before on attempt to load file without proper path.
If you have doubts, you can add some data into the DataSet, save it, load
it again and see if data was actually loaded.

As to missing file, by any chance, are you trying to locate this file on
desktop's hard drive using desktop's search and explorer?
If so, you won't be able to find it as emulator's file system is emulated
as well and is not mapped to desktop's file system.

If you're using file explorer on the emulator, could you please describe
how exactly you're navigating to the emulator's root folder?

[Ilya Tumanov [MS]]

You can not read files into the dataset from local hard drive. Emulator has
no access to local hard drive at all and is unaware of its existence.
It's not mapping files on your hard drive to \Program Files\Project or to
any other folder for that matter.
Emulator's file system is independent from desktop's file system and
physically located in the desktop RAM (might be persisted onto hard drive
as an image).

Project files (including XML you're loading) are not mapped from your hard

Not really. Emulator is very "real" in that sense, it's a separate entity.

Are you saying that even though I can READ the file into the dataset from

the local hard drive's directory (which the emulator is mapping as \Program
Files\Project\), I can't WRITE the file back to the same location?

So far, I haven't tried to find it inside the emulator and wasn't even

aware that it was that functional. Guess it's worth a try, though.

I'd say that's a concrete proof the file is saved.
Should file not be saved, you would get FileNotFound exception which you
had before on attempt to load file without proper path.
If you have doubts, you can add some data into the DataSet, save it, load
it again and see if data was actually loaded.

As to missing file, by any chance, are you trying to locate this file on
desktop's hard drive using desktop's search and explorer?
If so, you won't be able to find it as emulator's file system is emulated
as well and is not mapped to desktop's file system.

If you're using file explorer on the emulator, could you please describe
how exactly you're navigating to the emulator's root folder?

Sorry, I meant to tell you...

When I tried your suggestion of immediately creating another dataset

and
trying to read the file just "created", as in:

Dim ds As DataSet = New DataSet

ds.WriteXml("\Foo.xml")
MsgBox("Just executed the WriteXML command")
Dim anotherDs = New DataSet

anotherDs.ReadXml ("\Foo.xml")

MsgBox("Just executed the ReadXML command")

it executes with no exceptions --- and no file. I've looked for the

file
at all levels of the directory from which the app is running, both manually
and via Search. I already know where the app is READING the XML file from
and, since the path I give the writeXML function is exactly the same, it
seems the file should be there. If it is, though, it's invisible.

As posted earlier, a programmer at our corporate office tried to

write
XML within both Windows CE and Pocket PC emulators and it worked. This is a
very frustrating mystery...

I thought I might have the answer when I saw this in the

emulator's
Help

file:

The following hardware and drivers are not supported in the Emulator:

Universal serial bus (USB) devices

PC Card devices

Storage devices, which include compact flash (CF) cards and hard disks

File system drivers, which include file allocation table (FAT), compact
disc (CD), and digital video disc (DVD) drivers

IEEE 1394 devices

But when I had a couple of programmers at our corporate

headquarters
try

on both a Windows CE and Pocket PC emulator, it worked for them.

What am I missing?

Right now it's running on a Windows CE emulator and reading its input
XML into the dataset from the path noted in the code I've provided (using
variable sPath). I'm simply trying to write the XML back out to the same
path using the ds.writeXML(fullPath) command.

The only reason rights are being mentioned at all is because we're
trying to figure out why the XML is not getting written back out.

If I
use

one of the sample code pieces from the VB .NET Resource Kit ("How

To
Write

An Offline Application") that runs under the full .NET Framework,

it
works

great, but when I move down into the Compact Framework, it won't write.

To reiterate, it throws no exceptions, but the file just isn't there
--- anywhere --- when I look.

Wait a minute... Are you doing this on a Windows CE device or

Windows
CE does not have filesystem permissions. Or perhaps you expect to
find the
dataset xml written by the code on the device in your PC filesystem?

I'm trying to write a DataSet back out to the same location it
reads in
from with readXML(fullFilePath), just to a different

filename.
The

breezes right on through with no exceptions, but the file

there!

There's data in the DataSet and I have write rights to the

What could be happening and how do I get around it?

 

[Guest]

Please clarify one thing...
Are you saying that because I put the XML file into my project directory as content, it's being copied to the emulator (from my local directory, of course) and then being read from there? It makes perfect sense, if that's what you're saying.

Thank you so much for helping me understand.

You can not read files into the dataset from local hard drive. Emulator has
no access to local hard drive at all and is unaware of its existence.
It's not mapping files on your hard drive to \Program Files\Project or to
any other folder for that matter.
Emulator's file system is independent from desktop's file system and
physically located in the desktop RAM (might be persisted onto hard drive
as an image).

Project files (including XML you're loading) are not mapped from your hard
drive onto emulator file system; they are copied into it on deployment.
If you delete or change file in project folder, its copy in the emulator
will remain unchanged (until redeployed).
If you save or change file inside emulator, it will stay inside emulator
and won't be accessible on desktop.

Consider real device isolated from desktop (i.e. disconnected).
Can you save files on this device? Sure. Can you use your desktop to see
them?
Not really. Emulator is very "real" in that sense, it's a separate entity.

You have to use emulator's file explorer to check emulator's file system,

and via Search. I already know where the app is READING the XML

file
from

and, since the path I give the writeXML function is exactly the

same,
it

seems the file should be there. If it is, though, it's invisible.

As posted earlier, a programmer at our corporate office tried to write
XML within both Windows CE and Pocket PC emulators and it worked.

This
is a

very frustrating mystery...

Could you please describe how exactly you're looking for a file?
I also wonder if you get an exception on attempt to load saved file...

Best regards,

Ilya

I thought I might have the answer when I saw this in the emulator's
Help
file:

The following hardware and drivers are not supported in the Emulator:

Universal serial bus (USB) devices

PC Card devices

Storage devices, which include compact flash (CF) cards and hard
disks

File system drivers, which include file allocation table (FAT),
compact
disc (CD), and digital video disc (DVD) drivers

IEEE 1394 devices

But when I had a couple of programmers at our corporate headquarters
try
on both a Windows CE and Pocket PC emulator, it worked for them.

What am I missing?

Right now it's running on a Windows CE emulator and reading its
input
XML into the dataset from the path noted in the code I've provided
(using
variable sPath). I'm simply trying to write the XML back out to the
same
path using the ds.writeXML(fullPath) command.

The only reason rights are being mentioned at all is

because
we're

trying to figure out why the XML is not getting written back

out.
If I

use
one of the sample code pieces from the VB .NET Resource Kit

("How
To

Write
An Offline Application") that runs under the full .NET

Framework,
it

works
great, but when I move down into the Compact Framework, it

won't
write.

To reiterate, it throws no exceptions, but the file just isn't
there
--- anywhere --- when I look.

Wait a minute... Are you doing this on a Windows CE

device or
on

the
desktop? If on the device, what Write Rights are you talking
about?
Windows
CE does not have filesystem permissions. Or perhaps you expect to
find the
dataset xml written by the code on the device in your PC
filesystem?

location
it

reads in
from with readXML(fullFilePath), just to a different filename.
The
program
breezes right on through with no exceptions, but the file just
isn't
there!

There's data in the DataSet and I have write rights to the
fullFilePath
specified.

What could be happening and how do I get around it?
