IRTrans Support Forum

Hello,

I am actually rewriting HC-SKIPPER's connection module in order to use the .NET dll and abandon the active-x. It works great. It is really pleasant to deal with this dll
I encounter a problem though when trying (for tests purposes) to connect to the wrong IP. For example I write this code:

Try
Device = New IRTransServer("localhos")

Catch ex As IRTrans.NET.IRTransConnectionException
MsgBox("Wrong IP !")
End Try

An IRTrans.NET.IRTransConnectionException is indeed raised and the message is shown. But once I click on the OK button of the message, application breaks with this error:
System.NullReferenceException was unhandled
Message=La référence d'objet n'est pas définie à une instance d'un objet.
Source=IRTrans.NET
StackTrace:
à IRTrans.NET.IRTransServer.Close()
à IRTrans.NET.IRTransServer.Dispose(Boolean disposing)
à IRTrans.NET.IRTransServer.Finalize()
InnerException:

It seems that the error is inside the dll. What can I do to prevent my app from breaking ? Dll's release is 4.0.18.26026.

Thanks for your help.

Hi,
can you send us some code so that we can reproduce the problem here?

Then we will surely be able to fix that.

Hi,

I am developping in VB for .NET. But I've just tried with your c# example and it breaks the same:



private void Form1_Load(object sender, System.EventArgs e)
{
try
{
irt = new IRTransServer("localhos");

irt.StartAsnycReceiver ();

irt.IRReceive += new IRTrans.NET.IRTransServer.IRReceiveEventHandler (IRReceived);
}
catch (IRTransConnectionException ex)
{
MessageBox.Show(ex.Message);
}
}

You have to comment the protected override void Dispose method.

I notice that this error occurs only when I pass for example "localhos" instead of "localhost". If I pass a wrong address like "192.168.0.0" it does not break.

I have found a solution. Before calling the IRTransServer function I make a ping on the address. If the reply is success then I continue.

Hi,

Where can I get some detailled information about the methods, properties returned errors etc. for the object IRTransServer ?

How can I reload database with the .NET dll ?

Thanks for your help.

Hi,
currently we do not have comprehensive instructions for the .NET DLL. If you have any questions on some of the calls we can of course help you.

I will need to check how you can reload the database.

IRTrans

Hi,
here is how to reload the database:

Public Function ReloadDatabase() As IRTrans.NET.NETWORKSTATUS
Member von: IRTrans.NET.IRTransServer

Hi,

I can't find this method. Maybe I am not using the correct version of the dll:

Runtime version = v1.1.4322
Version = 2.7.2.0

This method is not listed in the Object Browser of visual studio.

Any idea ?

Hi,
looks like you are using a VERY old DLL.

Download our latest SW - it includes a current version of the DLL.

Indeed, its much better with the last realease

Thanks for your help !
