Dears,

Sometimes I'm getting following exception in my logs:

ERROR: 50: (SmppServer) Client connection failed, Exception: System.ObjectDisposedException: Safe handle has been closed
at System.Runtime.InteropServices.SafeHandle.DangerousAddRef(Boolean& success)
at Microsoft.Win32.Win32Native ...

Dears,

Now when I'm receiving huge count of requests( for example 100 TpS), I'm returning Zero Window to the client, which means (DON'T send again)

Sample response:

[TCP ZeroWindow] SMPP Submit_sm - resp: "Ok"

Please help to solve the problem.

Please send me the latest version. I've sent to you my license by email

Dear Alt,

In current time I can receive and reply request.
But I can't send Network initiated request to the mobile.

If I get in first part of user request 90, this means, than this is sample USSD reqiest, if I get 72: this is a answer for USSD menu.

I have only this rules.

What you think about ...

Dears,

I want to send network initiated USSD to the subscriber.

But I'm getting in mobile normal SMS.

My code:

SubmitSm req = new SubmitSm(tbServiceType.Text,
byte.Parse(tbSrcAdrTON.Text),
byte.Parse(tbSrcAdrNPI.Text),
tbSrcAdr.Text,
byte.Parse(tbDestAdrTON.Text),
byte.Parse(tbDestAdrNPI ...

Dear Alt,

Please reply.

Dear Mubarak,

Please try to use:

List<SubmitSmResp> submitSM = cSmpp[0].Submit(SMS.ForSubmit()
.From(srcAdr, srcTon, srcNpi)
.To(dstAdr, dstTon, dstNpi)
.Coding(coding)
.Text(tbSend));

Dear Alt,

I'm trying to use SubmitSm:

SubmitSm req = new SubmitSm(null,
srcAdrTON,
tbSrcAdrNPI,
srcAddr,
tbDestAdrTON,
tbDestAdrNPI,
dstAddr);
req.DataCoding = coding;
req.ShortMessage = messageText;
......

I get exception "Object reference is null ..." and I found the problem:

Dear Alt ...

Dear Alt,

Thank you very much.

Dear Alt,

I'm trying with DataCoding.Latin1, but results are the same.

Dear Alt,

Thank you for your reply.

I'm using Default data coding:

<add key="SMPP_DATA_CODING" value="Default"/>

Dear Alt,

I need to send messages with length more than 120 chars, and I'm can't use UCS2.

I was try to send in ASCII and UTF8, but the result is same.

client.MapEncoding(DataCodings.Default, Encoding.ASCII);

or

client.MapEncoding(DataCodings.Default, Encoding.UTF8);

Please reply.
