Getting Device Phone Number

[Matt]

Hi

I'm trying to get the Phone Number that the device uses to make outgoing
calls.

I've found two methods but neither seem conclusive and can return blank on
some devices:

OpenNETCF.Phone.Sim.Sim sim = new OpenNETCF.Phone.Sim.Sim();
if (sim.OwnNumbers.Count > 0)
{
string sMyNumber = sim.OwnNumbers[0].Address;
labelPhoneNo.Text = sMyNumber;
}
else
{
labelPhoneNo.Text =
SystemState.OwnerPhoneNumber.ToString();

Is there a better solution?

Many Thanks!

The Own Numbers feature of the SIM card is up to the operator and usage
varies greatly. The SystemState.OwnerPhoneNumber relies on the user having
entered their user information when they setup the device.
To retrieve the actual device number you can either use TAPI, or in most
cases the SmsGetPhoneNumber method.

[DllImport("sms.dll")]
private static extern int SmsGetPhoneNumber(byte[] buffer);


usage:-


string phoneNumber = string.Empty;

byte[] buffer = new byte[516];
int hresult = SmsGetPhoneNumber(buffer);

if(hresult == 0)
{
phoneNumber = System.Text.Encoding.Unicode.GetString(buffer, 4,
buffer.Length - 4);
int nullIndex = phoneNumber.IndexOf("\0");
if(nullIndex > -1)
{
phoneNumber = phoneNumber.Substring(0, nullIndex);
}

Thanks Peter - I'll try that!

Hi Peter,

I tried that but "SmsGetPhoneNumber" returns a large negative number
(-2147467259) so the routine fails

Could you point me in the direction of the TAPI solution?

Thanks
