Tag property

The ‘Tag’ value identifies the TLV. TLV’s are additional, often optional information that can be attached to any of the packets that are specified in the SMPP 3.4 or 5.0 protocol. Here’s a list of TLV’s that have been proposed in SMPP 3.4. You provider may use other, specific TLV’s, find these in the providers documentation.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsString = "Hello, World !"
WScript.Echo objTlv.Length
...

Length property

This is the length in bytes of the TLV ‘Value’ field. This property is read-only since it’s always inferred from the value field.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsString = "Hello, World !"
WScript.Echo objTlv.Length
...

ValueAsString property

Use this property to set or read a TLV Value that is specified as a ‘C-Octet’ string.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsString = "Hello, World !"
WScript.Echo objTlv.Length
...

ValueAsHexString property

Use this property to set or read a TLV Value that is specified as ‘Octet Data’ or ‘Octet String’.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsString = "Hello, World !"
WScript.Echo objTlv.Length
WScript.Echo objTlv.ValueAsHexString
...

ValueAsInt32 property

Use this property to set or read a TLV Value that is specified as a ‘4 Octet’ value.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsInt32 = 1
WScript.Echo objTlv.Length
WScript.Echo objTlv.ValueAsHexString
...

ValueAsInt16 property

Use this property to set or read a TLV Value that is specified as a ‘2 Octet’ value.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsInt16 = 1
WScript.Echo objTlv.Length
WScript.Echo objTlv.ValueAsHexString
...

ValueAsInt8 property

Use this property to set or read a TLV Value that is specified as an ‘Octet’ value.

Example:

Set objTlv = CreateObject("AxSms.Tlv")   
objTlv.Tag = 100
objTlv.ValueAsInt8 = 1
WScript.Echo objTlv.Length
WScript.Echo objTlv.ValueAsHexString
...

Clear method

This method resets all properties to their default values.

Parameters:

  • None

Return value:

None

Example:

Set objTlv = CreateObject("AxSms.Tlv")
objTlv.Clear
objTlv.Tag = 100
objTlv.ValueAsInt8 = 1
WScript.Echo objTlv.Length
WScript.Echo objTlv.ValueAsHexString
...
