[mohdis]

i send message in this way

Code: Select all

Dim resp As IList(Of SubmitSmResp)

resp = _client.Submit(SMS.ForSubmit().From(srcAdr, srcTon, srcNpi).To(dstAdr, dstTon, dstNpi).Coding(coding).Text(msg.Message).ExpireIn(TimeSpan.FromDays(1)).DeliveryReceipt())

  For Each msg_Status As SubmitSmResp In resp


                            Dim m As New UserDataHeader
                            m = msg_Status.Request.UserDataPdu.Headers(0)
Next

Hello mohdis,

Sorry for late response.

UserDataHeaderCollection has implicit conversion operator to byte array. So you can just assign UserDataPdu.Headers to byte array variable and then convert this array to hex string.

var req = SMS.ForSubmit().From(srcAdr, srcTon, srcNpi).To(dstAdr, dstTon, dstNpi).Coding(coding).Text(msg.Message).ExpireIn(TimeSpan.FromDays(1)).DeliveryReceipt().Create(_client);

foreach (var submitSm in req)
{
byte[] header = submitSm.UserDataPdu.Headers;

Console.WriteLine(ByteArray.ToHexString(header));
}

thank you .

another last Question :

is this correct way to send long message by syncmode to check if any part failed and try to send again ?


Dim pduBuilder As Inetlab.SMPP.Builders.ISubmitSmBuilder

pduBuilder = SMS.ForSubmit() _
.From(srcAdr, srcTon, srcNpi) _
.To(dstAdr, dstTon, dstNpi) _
.Coding(coding) _
.Text(msg.Message) _
.ExpireIn(TimeSpan.FromDays(1)) _
.DeliveryReceipt()



For Each xpdu In pduBuilder.Create(_client)
x += 1

Dim m_resp As SubmitSmResp = _client.Submit(xpdu)

If m_resp.Status = CommandStatus.ESME_ROK Then

FinalMessageStatus = True
' m_MsgId = xpdu.
m_MsgStatus = Int(m_resp.Status)
Thread.Sleep(10)
Else
Thread.Sleep(50)
m_resp = _client.Submit(xpdu) 'another try to failed part

End If

It depends on the response status.
For ESME_RTHROTTLED it will likely work, but could be possible that you need longer delay.

Also you need to take next xpdu.Sequence before repeat.
