Wap push error

[smitha.p]

I am trying to wap push from .net using GSMOUT in active experts library. using MO 200 GPRS modem. The sending sms is working.
But it is throwing the following error from wap push module.
'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.' while doing objWap.ConnectionType =objConstants.asWAPPUSH_SERVICE_INDICATION.
Can some one please help. I am attaching the code below.


string[] status = new string[2];
ASmsCtrl.WapPush objWap = new ASmsCtrl.WapPush();
ASmsCtrl.ConstantsClass objConstants = new ASmsCtrl.ConstantsClass();
objWap.ConnectionType = objConstants.asWAPPUSH_SERVICE_INDICATION;
//objWap.ConnectionType = 0;
objWap.URL = url;
objWap.Description = message;
objWap.SignalReference = "6532";
objWap.SignalAction = objConstants.asWAPPUSHSIGNAL_MEDIUM;
int nMessageParts = objWap.Encode();

GsmOut objGsmOut = new GsmOut();
objGsmOut.Device = ConfigurationSettings.AppSettings["gsmDevice"].
ToString();
objGsmOut.MessageType = objConstants.asMESSAGETYPE_DATA_UDH;
//asMESSAGETYPE_DATA_UDH;
objGsmOut.MessageRecipient = mPhoneNo;

for (int i = 0; i < nMessageParts; i++)
{
objGsmOut.MessageData = objWap.GetMessagePart(i);
objGsmOut.Send();

}

if (objGsmOut.LastError == 0)
{
status[0] = "1";
status[1] = objGsmOut.MessageReference.ToString();
}
else
{
status[0] = "0";
status[1] = objGsmOut.GetErrorDescription(objGsmOut.LastError);
}
objGsmOut.Clear();
return status;

Hi,

Thank you for your post. Can you try the following:

replace

ASmsCtrl.ConstantsClass objConstants = new ASmsCtrl.ConstantsClass();

with

ASmsCtrl.ConstantsClass objConstants = new ASmsCtrl.SmsConstantsClass();

Hope this solves the problem

There is no such class ASmsCtrl.SmsConstantsClass is the library.
