copied exe-file is not a valid application

Hi,
I have written a litte application (eMbedded Visual C++) for Pocket PC 2002
to copy an exe-file from the root-directory to the startmenu-directory.
It seems to work fine, but when I start the copied application (the exe-file) I get the message
"... is not a valid Pocket PC application"
What is wrong with this applcation?
Or does anyone know how to call Copy from an Pocket PC application directly?
Here is the code:
// Setup.cpp : Defines the entry point for the application.
//
#include "stdafx.h"
#define SOURCEFILE_NAME "\\banking.exe"
#define DESTINATIONFILE_NAME "\\Windows\\Start Menu\\banking.exe"
#define DESTINATIONFILE_NAME_GERMAN "\\Windows\\Startmenü\\banking.exe"
int WINAPI WinMain( HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
BOOL german = FALSE;
FILE *file = 0;
FILE *rfile = 0;
rfile = fopen (SOURCEFILE_NAME, "rb");
if (!rfile)
{
MessageBox (0, TEXT("Error"), TEXT("Setup"), MB_TOPMOST);
return 1;
}
file = fopen (DESTINATIONFILE_NAME_GERMAN, "wb");
if (!file)
file = fopen (DESTINATIONFILE_NAME, "wb");
else
german = TRUE;
if (file)
{
char buffer [1000];
size_t num_read = 0;
size_t num_written = 0;
size_t num_read_tot = 0;
size_t num_written_tot = 0;
do
{
num_read = fread (buffer, sizeof (char), 1000, rfile);
if (feof(rfile))
break;
num_read_tot += num_read;
if (num_read > 0)
{
num_written= fwrite (buffer, sizeof (char), num_read, file);
num_written_tot += num_written;
}
else
break;
} while (1);
fclose (file);
}
fclose (rfile);
DWORD attr = 0;
BOOL rc = 0;
attr = GetFileAttributes (TEXT(SOURCEFILE_NAME));
if (german)
rc = SetFileAttributes (TEXT(DESTINATIONFILE_NAME_GERMAN), attr);
else
rc = SetFileAttributes (TEXT(DESTINATIONFILE_NAME), attr);
MessageBox (0, TEXT("Ready"), TEXT("Setup"), MB_TOPMOST);
return 0;
}
// END

Hello,
You are trying to reinvent the wheel by copying yourself the info from the file. Use the CopyFile function.
But your error
"... is not a valid Pocket PC application"
Click to expand...
Click to collapse
has probably appeared for another reason...

You should also look at SHFileOperation

It's not a good idea to copy *.exe files to start menu...
Create a shortcut with CECreateShortcut(...) instead.
If this is part of a application setup (in a cab file) just create the shortcut with the build in features:
...
[DefaultInstall]
...
CEShortcuts = Shortcuts
...
[Shortcuts]
BankingMenuText,0,banking.exe
...
John

John,
thank you for your comment.
Perhaps you ore someone else can tell me how to create a shortcut (for the banking.exe) from a Pocket PC - application ?
(The background is as follows:
I want to deliver my banking-application on SD-Card;
a little setup-application on the SD-Card copies the banking.exe from SD-Card into the program-directory of the Pocket PC.
And last but not least this setup-application shoult insert a shortcut for the copied banking.exe in the Start Menu.

OK,
cabwiz.exe does exactly the job.
One open question:
How can I achieve, that after executing the cab-file is N O T deleted?

Create Shortcut with SHCreateShortcut.
Not deleting cab file : mark it as read-only on the desktop (before copying) 8)

Device Power Management in WM

Dear сolleagues and development guru!
I have some stopper in Power Management. I hope somebody will help me to understand.
Technologies: C#, .NET 3.5
The main point of application:
Make beep periodically.
Main problem is:
When PocketPC in active mode application running correct, but when PocketPC went to sleep mode it does not make a beep. As I understood speaker is turned off in sleep mode (like all other devices in PocketPC).
Question:
How can I turn on speaker in sleep mode?
Simply what I need is turn on speaker, make beep and back speaker to previous mode without wake up all device.
I tried code like this:
Code:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Media;
using System.Threading;
using System.Runtime.InteropServices;
namespace TestProject
{
static class Program
{
public const int POWER_NAME = 0x00000001;
public enum DevicePowerState : int
{
Unspecified = -1,
D0 = 0,
D1,
D2,
D3,
D4,
}
[DllImport("coredll.dll", SetLastError = true)]
public static extern int SetDevicePower(
string pvDevice,
int dwDeviceFlags,
DevicePowerState DeviceState
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr SetPowerRequirement(
string device,
DevicePowerState state,
uint deviceFlags,
IntPtr systemState,
ulong stateFlags
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern int ReleasePowerRequirement(IntPtr handle);
[MTAThread]
static void Main()
{
MessageBox.Show("Application is running...", "Confirmation", MessageBoxButtons.OK, MessageBoxIcon.Asterisk,MessageBoxDefaultButton.Button1);
string deviceName = "WAV1:"; // speaker
for (; ; )
{
// set D0 power value
IntPtr handle = SetPowerRequirement(deviceName, DevicePowerState.D0, 1, IntPtr.Zero, 0);
// make a beep
SystemSounds.Beep.Play();
// set default power value
ReleasePowerRequirement(handle);
Thread.Sleep(10000);
}
}
}
}
And like this:
Code:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Media;
using System.Threading;
using System.Runtime.InteropServices;
namespace TestProject
{
static class Program
{
public const int POWER_NAME = 0x00000001;
public enum DevicePowerState : int
{
Unspecified = -1,
D0 = 0,
D1,
D2,
D3,
D4,
}
[DllImport("coredll.dll", SetLastError = true)]
public static extern int SetDevicePower(
string pvDevice,
int dwDeviceFlags,
DevicePowerState DeviceState
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern IntPtr SetPowerRequirement(
string device,
DevicePowerState state,
uint deviceFlags,
IntPtr systemState,
ulong stateFlags
);
[DllImport("coredll.dll", SetLastError = true)]
public static extern int ReleasePowerRequirement(IntPtr handle);
[MTAThread]
static void Main()
{
MessageBox.Show("Application is running...", "Confirmation", MessageBoxButtons.OK, MessageBoxIcon.Asterisk,MessageBoxDefaultButton.Button1);
string deviceName = "WAV1:"; // speaker
int resDevicePowerOn = SetDevicePower(deviceName, POWER_NAME, DevicePowerState.D0);
for (; ; )
{
// make a beep
SystemSounds.Beep.Play();
Thread.Sleep(10000);
}
}
}
}
But any of these codes does not work - there are no beep in sleep mode.

Hi, I just happened to find an article from codeproject.
You may want to take a look at it.
http://www.codeproject.com/KB/mobile/WiMoPower1.aspx
I think what you need is cerunappattime.

It seems you are enabling the audio device to run in low-power mode, but you are not actually telling the CPU to keep running ("unattended mode").
Lookup PowerPolicyNotify, specifically PPN_UNATTENDEDMODE.
You may also need to periodically call SHIdleTimerResetEx and/or SystemIdleTimerReset to keep the device active in unattended mode or it will still truely suspend.

Prevent the system enter sleep mode
The system will stop all activitis when the system enter sleep mode.So you must prevent the system enter sleep mode.
The system sleep mode：
on -> unattended -> suspend
You can run：
on -> unattended -> resuming
my code：time up is system on

Deploy XAP without Visual Studio

Is it possible to deploy my XAP file without using Visual Studio in either hacked or original emulator image?

With XNA tool WP.exe you can install .xap to Emulator or Device WITHOUT VisualStudio.
On my machine, XNAGSv4=C:\Program Files\Microsoft XNA\XNA Game Studio\v4.0\Tools
Command:
wp install [options] <xap> <app id> <icon> <xapcache>
Example:
%XNAGSv4%\Tools\wp.exe install HellpWP7.xap 71f6d153-0759-4d6e-9bcd-de9a49d8f232 ApplicationIcon.png XapCacheFile.xml
* app id: The GUID found in Propeties\AssemblyInfo.cs
* ApplicationIcon.png: Found in the output directory.
* XapCacheFile.xml: Found in the intermediate (obj) directory.

I have read that the approach using wp.exe from XNA only works for XNA apps. Here is another approach which makes use of CoreCon API: h**p://justinangel.net/WindowsPhone7EmulatorAutomation

Nice, and only your second post.. Where did you get this?

That's reflected from XapDeploy

You will have to use XapDeploy tool. It requires Zune running on the same environment. You can also use WPConnect, a console tool, if you have Zune installed, see msdn.microsoft.com/en-us/library/gg180729(VS.92).aspx

[Q] Writing in an XML File Problem

Hey Guys!
I'm sitting in front of an XML-Problem for five days now and really don't know what's to do. Expect of asking you.
I want to write a small shopping list application that manages the data in an XML-File looking like that:
Code:
<?xml version="1.0" encoding="utf-8" ?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
(...)
I have a ListBox called ItemShowcase that I fill with instances of my ShowCaseEntry-Class
Reading Data from the FIle works perfectly with this code:
Code:
private void updateItemList()
{
// load XML-File
var items = XElement.Load("MissingItems.xml");
foreach (var a in items.Elements())
{
ShowCaseEntry sce = new ShowCaseEntry(a.Element("Name").Value, "Store: " + a.Element("Store").Value, false);
ItemShowcase.Items.Add(sce);
}
}
No Problem until here.
But now I want to add a new Iem to my XML-File.
I have 2 Textfields in what I ask for the Item-Name and Store-Name. Repeat is always true.
I tried that:
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
// XML-Datei Laden
var items = XDocument.Load("MissingItems.xml");
// neues Item erstellen
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat) );
// Hinzufügen und spreichern
items.Root.Add(newItem);
FileStream F = new FileStream("MissingItems.xml", FileMode.Open);
items.Save(F);
}
The last line give me the following Error:
Attempt to access the method failed: System.IO.FileStream..ctor(System.String, System.IO.FileMode)
Is anyone here who would help me?
You would save my weekend!
Thank you so much!
Best wishes and greets
Robby

Try something like this:
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
xml.Save(isoStream);
isoStream.Close();

First of all thanks for your answer.
Unfortunately I don't really know how to add the XML-Items.
Like this?
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
var items = XDocument.Load("MissingItems.xml");
XElement newItem = new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat));
items.Root.Add(newItem);
items.Save(isoStream);
isoStream.Close();
}
Another answer would be very nice
Best regards
Robby

I don't have time to test it but hopefully this works for you.
Code:
public void addXMLItem(String name, String store, Boolean repeat)
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
//Add your xml items here.
XDocument items = XDocument.Load(isoStream);
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat)));
items.Save(isoStream);
isoStream.Close();
}

Thank you really much for your engangement, but there is still one problem.
In this line the program throws an XML-Error called "root element is missing":
XDocument items = XDocument.Load(isoStream);
How to explain the Load-Method that "Items" is my root Element?
Greets
Robby

Sorry my code had errors. This is tested and working.
Code:
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument items = XDocument.Load(isoStream);
isoStream.Close();
items.Element("Items").Add(
new XElement("Item",
new XElement("Name", name),
new XElement("Store", store),
new XElement("Repeat", repeat.ToString())));
isoStream = new IsolatedStorageFileStream("MissingItems.xml", FileMode.Create, FileAccess.Write, isoStore);
items.Save(isoStream);
isoStream.Close();
That code results in this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<Items>
<Item>
<Name>Bananas</Name>
<Store>supermarket</Store>
<Repeat>true</Repeat>
</Item>
<Item>
<Name>LG E900 Optimus 7</Name>
<Store>superhandy</Store>
<Repeat>false</Repeat>
</Item>
<Item>
<Name>Test Name</Name>
<Store>Test Store</Store>
<Repeat>False</Repeat>
</Item>
</Items>

I really, really thank you for your anxiety. Thank you for your time, but I just have one more error.
This line throwes an Isolated Storage Exception called "Operation not permitted on IsolatedStorageFileStream.":
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
You would save my week with a short answer!
Thank you so much till yet
Robby

It sounds like the file stream is already open somewhere else. If you are doing any other reads or writes to the file prior to your addxmlitem method you need to close the stream before calling addxmlitem.

Not really

Thanks a lot for your engagement!

I'n not really sure why that's happening. The only thing I can think of is XElement.Load() is causing the problem so here's how to use XDocument.Load() instead. I really hope this works for you because I'm out of ideas.
Code:
private void updateItemList()
{
IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication();
IsolatedStorageFileStream isoStream;
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
XDocument xml = XDocument.Load(isoStream);
var items = from c in xml.Elements("Items").Elements("Item")
select new {
name = c.Element("Name").Value,
store = c.Element("Store").Value,
repeat = c.Element("Repeat").Value
};
foreach (var item in items)
{
ShowCaseEntry sce = new ShowCaseEntry(item.name, "Store: " + item.store, false);
ItemShowcase.Items.Add(sce);
}
isoStream.Close();
}

Same Error on this line:
isoStream = new IsolatedStorageFileStream("MissingItems.xml", System.IO.FileMode.Open, System.IO.FileAccess.Read, isoStore);
Operation not permitted on IsolatedStorageFileStream.
I'm at the end of my motivation
I really tried everything, you really tried everything and I cannot find anything helpful to this error message..
Does anyone has an idea?
Does this line works for you?
Big Thanks to Ren13B till yet!

Attached is my working test project. Maybe it will help you.

If you are accessing the Isolated Storage from within a referenced assembly, you will need to access the IsolatedStorageFile for that assembly

Thanks for your reply but how to do that?

MAPIdotnet and binary message body

Best all,
A while ago I tried to make a simple application which can export all my smses and mmses to my local database server. It runs quite smoothly but I can't manage to get the correct mms body data. It seems that about 5% of the exported body data(for example a sent picture in jpeg format) is different from the original jpeg picture/body data: the exported picture data can't be viewed, it is corrupt.
I suspect the method of exporting the data must be changed from string to binary, but I don't know exactly how to proceed.
I'm using C# 2008 in combination with the MAPIdotnet library, and my target device is a HTC HD Mini with Windows Mobile 6.5 professional.
The part of my code where it's going wrong:
Code:
ASCIIEncoding asen = new ASCIIEncoding();
byte[] ba = asen.GetBytes(s);
bw.Write(ba);
bw.Close();
fs.Close();
if (messages[msgID].Body != null)
{
FileStream fs2 = File.Create("\\Opslagkaart\\Debug\\body_" + Convert.ToString(msgID) + ".dat");
BinaryWriter bw2 = new BinaryWriter(fs2);
System.Text.UnicodeEncoding enc = new System.Text.UnicodeEncoding();
byte[] file = enc.GetBytes(messages[msgID].Body);
//bw2.Write(messages[msgID].Body);
bw2.Write(file);
bw2.Close();
fs2.Close();
}
In combination with MAPIdotnet's code:
Code:
public string Body
{
get
{
IStreamChar s = (IStreamChar)this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0);
if (s == null)
return "";
IntPtr p = Marshal.AllocHGlobal(4);
char[] b = new char[3];
StringBuilder str = new StringBuilder();
int c, len = b.Length * 2;
do
{
s.Read(b, len, p);
c = Marshal.ReadInt32(p);
str.Append(new string(b, 0, c / 2));
}
while (c >= len);
Marshal.FreeHGlobal(p);
return str.ToString();
}
}
Can somebody give a hint of how to proceed?
Thanks,

I suddenly got some more inspiration and, with help from google, I've managed to correctly retrieve the binary jpeg attachments of two of my mmses.
The code part of my program:
Code:
//if (messages[msgID].BodyBinary.Length>0)
//{
FileStream fs2 = File.Create("\\Opslagkaart\\Debug\\body_" + Convert.ToString(msgID) + ".dat");
BinaryWriter bw2 = new BinaryWriter(fs2);
bw2.Write(messages[msgID].BodyBinary);
bw2.Close();
fs2.Close();
//}
The code part of the customized MAPIdotnet:
Code:
private static IntPtr ReadBuffer;
static int Read(OpenNETCF.Runtime.InteropServices.ComTypes.IStream strm, byte[] buffer)
{
if (ReadBuffer == IntPtr.Zero) ReadBuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(typeof(int)));
try
{
strm.Read(buffer, buffer.Length, ReadBuffer);
}
catch (NullReferenceException e)
{
//do nothing
}
return Marshal.ReadInt32(ReadBuffer);
}
public byte[] BodyBinary
{
get
{
int buffsize = 1024*1024*2; /* If mms body is bigger than 2MB we have a problem here */
byte[] buffer = new byte[buffsize];
Read(this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0), buffer);
byte[] data = buffer;//ms.ToArray();
Marshal.FreeCoTaskMem(ReadBuffer);
return data;
}
}
But now ALL bodies are saved as 2MB files.. including the empty ones from for example a sms. And not all mms bodies are of the max size of 2mb. My carrier/phone supports up to 1MB. Perhaps I need to get some 'dynamic size' buffer instead of the fixed one. Does anyone have an idea on how to determine the size of the
this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0)
Click to expand...
Click to collapse
stream ?

I've solved all my problems by means of the following code (for mapidotnet):
Code:
private static IntPtr ReadBuffer;
static int Read(OpenNETCF.Runtime.InteropServices.ComTypes.IStream strm, byte[] buffer)
{
int returnvalue = 0;
if (ReadBuffer == IntPtr.Zero) ReadBuffer = Marshal.AllocCoTaskMem(Marshal.SizeOf(typeof(int)));
try
{
strm.Read(buffer, buffer.Length, ReadBuffer);
returnvalue = Marshal.ReadInt32(ReadBuffer);
}
catch (NullReferenceException e)
{
returnvalue = 0;
}
return returnvalue;
}
public byte[] BodyBinary
{
get
{
int newdatasize = 0;
int buffsize = 1024*1024*3; /* If mms body is bigger than 3MB we have a problem here */
byte[] buffer = new byte[buffsize];
newdatasize = Read(this.msg.OpenProperty(cemapi.PropTags.PR_BODY, 0), buffer);
if (newdatasize < 0) { newdatasize = 0; }
byte[] data = new byte[newdatasize];
Buffer.BlockCopy(buffer, 0, data, 0, newdatasize);
Marshal.FreeCoTaskMem(ReadBuffer);
return data;
}
}
Now all is working fine and the exported files are of their own real size. I'm sure the above code can be optimized but it's working good now.
