GuruxSMS component

This guide shows how to use Gurux SMS component (GXSMS) in the Visual Studio .NET environment using the C# language. Source code is available at sourceforge.net

Adding GXSMS component to the project

Start Visual Studio .NET
Open the project where you want to add the GXSMS component, or create a new one
Open Toolbox

Note:

implement it manually

Under Gurux tab, select the component, and drag and drop it on the form
Allow the use of any version of the media component:
- Select the component.
- In Solution Explorer view, in the References folder, select Gurux.GuruxSMS.
- In Properties view, set Specific Version to False.

Using components with .NET

You can either drag the component to the form, or create it dynamically.

Creating component dynamically

To create component in runtime, select Add Reference in the Project menu. The dialog shows available components, select the one(s) to use (in this case GXSMS component). Click OK to finish. The following example shows how to create a GXSMS component.

using GuruxGuruxSMS;
//Create new component
GXSMS GXSMS1 = new GXSMSClass();

Setting Media Properties

You can either select appropriate settings in the Properties dialog or edit the settings programmatically.

'Set receiver phone number
GXSMS1.ReceiverNumber = "Receiver phone number";
'Set port where Modem or phone is found
GXSMS1.Port = "Com1";
GXSMS1.Open();
GXSMS1.Send("Hello World", "");

Sending and receiving packets

All data is sent asynchronously. Response is received as a Received event message.

Receiving event messages

To receive event sent by the GXSMS component, select the component by right-clicking it on the form and select Properties. Create handlers for OnError and OnReceived methods.

To create a handler, select an event and enter name for the handler. In the following example, received data is converted to string and stored.

private void gxsms1_OnReceived(object sender, Gurux.GuruxSMS.GXSMSMessage SMSMessage, string SenderInfo)
{
    //Update data to the edit box.
    ReceiveDataText.Text += SMSMessage.Data;
    //Update Sender Information to the edit box.
    SenderText.Text = SenderInfo;
}

private void gxSMS1_OnError(object sender, string ErrorInfo)
{
    MessageBox.Show(sender.ToString());
}

Error Handling

It's very important to consider error handling when sending and receiving data. The connection can drop down, or something else unexpected may happen. If something unwanted happens, GXSMS component returns error. The following example shows how to handle errors in .NET.

try
{
	object data = Convert.ChangeType("Hello", System.TypeCode.Object);
	string receiver = null;
	GXSMS1.Send(ref data, ref receiver);
}
catch(Exception ex)
{
	MessageBox.Show(ex.ToString());
}
