Connection to GPRS with P/Invoke

TheMSsForum.com: The Microsoft Software Forum

hello
i m using VS 2003 with C# in CF 1.0.
i have made application of chatting client. my requirement is when
user bind to any socket it first made connection of GPRS. so can some
one give me code of how to connect to GPRS in CF 1.0/
i have following code. but it is not working.

public class GPRSConnection
{
const int S_OK = 0;
const uint CONNMGR_PARAM_GUIDDESTNET = 0x1;
const uint CONNMGR_FLAG_PROXY_HTTP = 0x1;
const uint CONNMGR_PRIORITY_USERINTERACTIVE = 0x08000;
const uint INFINITE = 0xffffffff;
const uint CONNMGR_STATUS_CONNECTED = 0x10;
static Hashtable ht = new Hashtable();

static GPRSConnection()
{
ManualResetEvent mre = new ManualResetEvent(false);
mre.Handle = ConnMgrApiReadyEvent();
mre.WaitOne();
CloseHandle(mre.Handle);
}

~GPRSConnection()
{
ReleaseAll();
}

public static bool Setup(Uri url)
{
return Setup(url.ToString());
}

public static bool Setup(string urlStr)
{
ConnectionInfo ci = new ConnectionInfo();
IntPtr phConnection = IntPtr.Zero;
uint status = 0;

if (ht[urlStr] != null)
return true;

if (ConnMgrMapURL(urlStr, ref ci.guidDestNet, IntPtr.Zero) != S_OK)
return false;

ci.cbSize = (uint) Marshal.SizeOf(ci);
ci.dwParams = CONNMGR_PARAM_GUIDDESTNET;
ci.dwFlags = CONNMGR_FLAG_PROXY_HTTP;
ci.dwPriority = CONNMGR_PRIORITY_USERINTERACTIVE;
ci.bExclusive = 0;
ci.bDisabled = 0;
ci.hWnd = IntPtr.Zero;
ci.uMsg = 0;
ci.lParam = 0;

if (ConnMgrEstablishConnectionSync(ref ci, ref phConnection,
INFINITE, ref status) != S_OK &&
status != CONNMGR_STATUS_CONNECTED)
return false;

ht[urlStr] = phConnection;
return true;
}

public static bool Release(Uri url)
{
return Release(url.ToString());
}

public static bool Release(string urlStr)
{
return Release(urlStr, true);
}

private static bool Release(string urlStr, bool removeNode)
{
bool res = true;
IntPtr ph = IntPtr.Zero;
if (ht[urlStr] == null)
return true;
ph = (IntPtr)ht[urlStr];
if (ConnMgrReleaseConnection(ph, 1) != S_OK)
res = false;
CloseHandle(ph);
if (removeNode)
ht.Remove(urlStr);
return res;
}

public static void ReleaseAll()
{
foreach(DictionaryEntry de in ht)
{
Release((string)de.Key, false);
}
ht.Clear();
}

[StructLayout(LayoutKind.Sequential)]
public struct ConnectionInfo
{
public uint cbSize;
public uint dwParams;
public uint dwFlags;
public uint dwPriority;
public int bExclusive;
public int bDisabled;
public Guid guidDestNet;
public IntPtr hWnd;
public uint uMsg;
public uint lParam;
public uint ulMaxCost;
public uint ulMinRcvBw;
public uint ulMaxConnLatency;
}

[DllImport("cellcore.dll")]
private static extern int ConnMgrMapURL(string pwszURL, ref Guid
pguid, IntPtr pdwIndex);

[DllImport("cellcore.dll")]
private static extern int ConnMgrEstablishConnectionSync(ref
ConnectionInfo ci, ref IntPtr phConnection, uint dwTimeout, ref uint
pdwStatus);

[DllImport("cellcore.dll")]

[DllImport("cellcore.dll")]
private static extern int ConnMgrReleaseConnection(IntPtr

so please help me

Can you elaborate on "it is not working", are you getting errors at compile
time, or during execution? exactly where in the code and what return values,
exceptions etc

sorry for not sending u full code. this is the code to call the
GPRSConnectin class which i write it in earlier post.

string url =3D "www.msn.com";
bool res =3D GPRSConnection.Setup("http://" + url + "/");
if (res)
{
TcpClient tc =3D new TcpClient(url, 80);
NetworkStream ns =3D tc.GetStream();
byte[] buf =3D new byte[100];
ns.Write(buf, 0, 100); ns.Close();
tc.Close();
MessageBox.Show("Wrote 100 bytes");
}
else
{
MessageBox.Show("Connection establishment failed");
}


if (ConnMgrEstablishConnectionSync(ref ci, ref phConnection,
INFINITE, ref status) !=3D S_OK &&
status !=3D CONNMGR_STATUS_CONNECTED)
return false;

sorry for not sending u full code. this is the code to call the
GPRSConnectin class which i write it in earlier post.

string url =3D "www.msn.com";
bool res =3D
GPRSConnection.Setup("http://" + url + "/");
if (res)
{
TcpClient tc =3D new
TcpClient(url, 80);
NetworkStream ns =3D
tc.GetStream();
byte[] buf =3D new byte[100];
ns.Write(buf, 0,
100); ns.Close();
tc.Close();
MessageBox.Show("Wrote 100
bytes");
}
else
{
MessageBox.Show("Connection
establishment failed");
}
this function return false in the main class. bcoz of that a
messagebox appear "Connection Established Failed". can u tell me y it
always retuen false.
///////////////////////////////////////////////
if (ConnMgrEstablishConnectionSync(ref ci, ref phConnection,
INFINITE, ref status) !=3D S_OK &&
status !=3D CONNMGR_STATUS_CONNECTED)
return false;

Step through the code in the debugger. First check if ConnMgrMapURL is
succeeding and returning a valid Guid for the connection. If this is good
and the connection attempt is still failing look at the status returned and
call Marshal.GetLastWin32Error() after CommMgrEstablishConnectionSync has
returned false for a more detailed error response.

sorry for not sending u full code. this is the code to call the
GPRSConnectin class which i write it in earlier post.

string url = "www.msn.com";
bool res =
GPRSConnection.Setup("http://" + url + "/");
if (res)
{
TcpClient tc = new
TcpClient(url, 80);
NetworkStream ns =
tc.GetStream();
byte[] buf = new byte[100];
ns.Write(buf, 0,
100); ns.Close();
tc.Close();
MessageBox.Show("Wrote 100
bytes");
}
else
{
MessageBox.Show("Connection
establishment failed");
}
this function return false in the main class. bcoz of that a
messagebox appear "Connection Established Failed". can u tell me y it
always retuen false.
///////////////////////////////////////////////
if (ConnMgrEstablishConnectionSync(ref ci, ref phConnection,
INFINITE, ref status) != S_OK &&
status != CONNMGR_STATUS_CONNECTED)
return false;

I have the same class in my code. Opening gprs and readind from an address is
not a problem to me. Do you know how to close (hang up) the GPRS connection
with all these functionalities? I tryed all, even RasHangUp but stil no
result. I just wana now how to obtain tha same efect with closing manualy the
GPRS connection (phone line hanged up). Thanks very
