How to send a file from a pocket pc to another pocket pc using C#.Net?

I am using windows mobile 5.0 in dot net. I need to send a file from one pocket pc to another pocket pc via Bluetooth using c#.

Is there any sample for sending file using C#.Net?

Hi,
i hope that u know the discovering the bluetooth enabled devices and connect with that selected devices... u dont know the method of file sendings..
This following code will explain the file sending concept.. For file sending we shall use third party tool called InTheHand... U can download the InTheHand Software and install it...
After that u can add that dll in ur reference..... Lets go through the following code after connecting the devices with ur device.. For example the file, u have to send is "sample.txt" which is in "C:\samplefolder\sample.txt"....



string fName = Path.GetFileName(@"C://samplefolder//sample.txt");
string fType = "";
StreamReader sr = File.OpenText(fileName);
string fFileContent = sr.ReadToEnd();
sr.Close();

//send client request, start put
int result = OBEXRequest("PUT",fName,fType, fFileContent);

switch (result)
{
case 160: // 0xa0
MessageBox.Show("File Send");
break;

case 197: // 0xc5
MessageBox.Show("Method not allowed");
break;

case 192: // 0xc0
MessageBox.Show("Bad Request");
break;

default:
MessageBox.Show("Other Error");
break;
}
}

else
{
MessageBox.Show("Failed to connect to OBEX Server");
}
}

private int OBEXRequest(string tReqType,string tName,string tType, string tFileContent)
{
int i;
int offset;
int packetsize;
byte reqtype = 0x82;

int tTypeLen = 0x03;
int typeheadsize;
int typesizeHi = 0x00;
int typesizeLo = 0x03;

if (tReqType == "GET")
{
reqtype = 0x83; // 131 GET-Final
}

if (tReqType == "PUT")
{
reqtype = 0x82; // 130 PUT-Final
}

packetsize = 3;

//Name Header
int tNameLength = tName.Length;
int nameheadsize = (3 + (tNameLength * 2) + 2);
int namesizeHi = (nameheadsize & 0xff00) / 0xff;
int namesizeLo = nameheadsize & 0x00ff;
packetsize = packetsize + nameheadsize;

if (tType != "")
{
//Type Header
tTypeLen = tType.Length;
typeheadsize = 3 + tTypeLen + 1;
typesizeHi = (typeheadsize & 0xff00) / 0xff;
typesizeLo = typeheadsize & 0x00ff;
packetsize = packetsize + typeheadsize;
}

//Body
int fileLen = tFileContent.Length;
int fileheadsize = 3 + fileLen;
int filesizeHi = (fileheadsize & 0xff00) / 0xff; ;
int filesizeLo = fileheadsize & 0x00ff; ;

byte[] tSendByte = new byte[packetsize];

//PUT-final Header
tSendByte[0] = reqtype; // Request type e.g. PUT-final 130
tSendByte[1] = Convert.ToByte(packetsizeHi); // Packetlength Hi
tSendByte[2] = Convert.ToByte(packetsizeLo); // Packetlength Lo

offset = 2;

//Name Header
tSendByte[offset + 1] = 0x01; // HI for Name header
tSendByte[offset + 2] = Convert.ToByte(namesizeHi); // Length of Name header (2 bytes per char)
tSendByte[offset + 3] = Convert.ToByte(namesizeLo); // Length of Name header (2 bytes per char)

// Name+\n\n in unicode
byte[] tNameU = System.Text.Encoding.BigEndianUnicode.GetBytes(tNa me);
tNameU.CopyTo(tSendByte, offset + 4);

offset = offset + 3 + (tNameLength * 2);
tSendByte[offset + 1] = 0x00; // null term
tSendByte[offset + 2] = 0x00; // null term

//Body
tSendByte[offset + 1] = 0x49; //HI End of Body 73
tSendByte[offset + 2] = Convert.ToByte(filesizeHi); //
tSendByte[offset + 3] = Convert.ToByte(filesizeLo); //1k payload + 3 for HI header

for (i = 0; i <= (fileLen - 1); i++)
{
tSendByte[offset + 4 + i] = Convert.ToByte(Convert.ToChar(tFileContent.Substri ng(i, 1)));
}
//tSendByte[offset+4+fileLen] = 0x00; // null terminator

offset = offset + 3 + fileLen;

stream.Write(tSendByte, 0, tSendByte.Length);

//listen for server response

//TODO: can hang here forever waiting response...

Hi aman,
I have another doubt.. Like Bluetooth facilities, we have WI-FI Facilities in mobile... I need to enable Wi-Fi services programmatically in windowsmobile using C#...Is it possible to enable this functionality....If u came to know, just share it here......
