Try this

Code: [Select]

Imports Keyence.AutoID.SDK
...
Dim m_reader As ReaderAccessor = New ReaderAccessor("192.168.111.104")
...

m_reader.Connect(AddressOf ReceivedDataAction)
...
Private Sub ReceivedDataAction(data As Byte())
        'Define received data actions here.Defined actions work asynchronously.
        '"ReceivedDataWrite" works when reading data was received.
        BeginInvoke(New delegateUserControl(AddressOf ReceivedDataWrite), System.Text.Encoding.ASCII.GetString(data))
End Sub
...
m_reader.Dispose()

Make sure to install the run time C++ library SR SDK.
Referencing two Keyence.AutoID.SDK.dll & Communication.dll

I rewrote the whole program to use the methods used in your reply. It has not crashed yet. It is been almost over a week now.
Thanks to everyone who replied. I really appreciate this.
Thank you Archie for making AHMI.

I have to try that. I have used a different sample program to make this.

Does the PC completely freeze or do you get an exception crash?

Just app freezes. It doesn't show any exceptions. I will have to close the app from the taskbar.

This what shows up everytime. It creates this exception every time
Exception thrown: 'System.FormatException' in mscorlib.dll
Exception thrown: 'System.FormatException' in mscorlib.dll

Is there anyway I can get the exception details when it freezes when I run the release version of the app. because this happens mostly when I run the EXE file.

@Archie you got to help me here . Initially I used messaging to communicate with the Sr-1000 barcode scanner. But I got into problems when I had to modify anything on the subroutine where I had message instructions. Rockwell says its a bug in RSlogix 500 and Rockwell said they don't fix this for Micrologic Controllers. Otherwise I was using AHMI only to use the SQL Compact Server. I dont see anything when it crashes. Also it doesnt do that on debug mode. It happens all the time when I run it from the debug or release folder.

I am using AHMI for connecting a Micrologix 1100 to SQL compact server. I have Keyence libraries to trigger a barcode scanner as well. But it crashes unexpectedly. I have been getting FormatExceptions all the time on the output. I tried to resolve it as much as possible. Any thoughts?
