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"

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,
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)

Please help with getting the MAC address in C++ for WM6.1 Pro

Hi
I'm trying to get the MAC address of my windows mobile 6.1 device, but i am just not succeeding. Can anybody help ?
This is what i have tried....really basic, but it doesnt work.
void CMAC_testDlg::OnBnClickedButton1()
{
CString mem_MAC;
IP_ADAPTER_INFO AdapterInfo[2];
DWORD dwBufSize = sizeof(AdapterInfo);
DWORD dwStatus = GetAdaptersInfo(AdapterInfo, &dwBufSize);
PIP_ADAPTER_INFO pAdapterInfo = AdapterInfo;
do
{
mem_MAC = pAdapterInfo->Address;
pAdapterInfo = pAdapterInfo->Next;
}
while(pAdapterInfo);
CEdit *pIP = (CEdit*)GetDlgItem(IDC_EDIT1);
pIP->SetWindowText(mem_MAC);
}
Thank you

Turn off GPRS

I'm looking for a way to turn off the data (GRPS)
Search didn't brought me anything usefull, I'm sure there is somwhere the data but can't find it.
I'm especially need it for WM 6.5 (HD2)

Search around for Modaco's NoData program. It's late and I'm too tired to search it up for you right now.

Thanks for the replay but it’s not what I meant, sorry for not be clarify.
I know the NoData app and actually i just finish writing something similar but more user friendly, hope to release it asap (Now I have problem with the icon )
What I’m looking is a way to turn off programmatically the data connection of the device, what the CommManager in the HTC sense do.
I tried to use the RAS api but it didn't work

look for jmlcomm.exe here at xda and use it in your app.simple command line call.and free to use.

Thanks for the idea, I'll try it.
But I prefer to do it directly from my app. without calling external tool.

I found a solution!
Its from few posts in the net, don't remember where exactly with some modification of me.
here is the code I use, if someone else will need it:

Webclient Help

how do i replicate this under windows mobile. The first function works flawlessly however the second version (Which is required to run on windows mobile 6.1-6.5) doesn't.. If anyone has any idea how to fix it i'm willing to try it out.
Thanks
Code:
private static byte[] WebPost(string url, byte[] data)
{
var webClient = new WebClient();
return webClient.UploadData(url, data);
}
This dont.
Code:
private static byte[] WebPost(string url, byte[] data)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.Timeout = 10000; // 10 secs
request.Method = "POST";
byte[] requestPostBuffer = System.Text.Encoding.GetEncoding(1252).GetBytes(ByteArrayToStr(data));
request.ContentLength = requestPostBuffer.Length;
Stream requestPostData = request.GetRequestStream();
requestPostData.Write(requestPostBuffer, 0, requestPostBuffer.Length);
requestPostData.Close();
// initialize the httpweresponse object
HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse();
// set our encoding
Encoding enc = System.Text.Encoding.GetEncoding(1252);
//initialis the webresponse stream with our encoding
StreamReader webResponseStream = new StreamReader(webResponse.GetResponseStream(),enc);
// create a string to copy it all into.
string streamedData = webResponseStream.ReadToEnd();
webResponse.Close();
webResponseStream.Close();
byte[] convertedResponse = StrToByteArray(streamedData);
convertedResponse = Encoding.Convert(System.Text.Encoding.Default, Encoding.GetEncoding(1252),convertedResponse);
return convertedResponse;
}

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)

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.
