Basic Button Crash (Version 3.9.9.24)

[Bvillalobos]

Hi Dears I an making a process demo and everything goes fine until my application began to crash in random way the following piece of code appear with the error, I am using vertion 3.9.9.24:

Private Sub ReleaseValue()
        Try
            Select Case m_OutputType
                Case MfgControl.AdvancedHMI.Controls.OutputType.MomentarySet : m_ComComponent.Write(m_PLCAddressClick, 0)
                Case MfgControl.AdvancedHMI.Controls.OutputType.MomentaryReset : m_ComComponent.Write(m_PLCAddressClick, 1)
            End Select
        Catch ex As MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException

            If ex.ErrorCode = 1808 Then
                DisplayError("""" & m_PLCAddressClick & """ PLC Address not found")
            Else
                DisplayError(ex.Message)
            End If
        End Try
    End Sub

When the error appear the IDE higligth the follow word m_ComComponent in the basic button file lines 469 and 470.

Would you help me to fix it ?

Thanks in advance !!

You don't say what the error is. My guess is that you have the Exception setting set to stop on all Common Language Runtime Exceptions and you have a PLC communication issue.

Does this occur if you are not running inside the IDE?

Hi Archy thank for answer, I have read a lot of post from you I think you are making a wonderful work.

Archi I will post the error number the next time that it appears, I just have tested the application inside the IDE, one of my question is why the Cath sentence I not working? At the begining I believed that the error was different of the error number in the if sentence so I commented the it and wrote an unconditional Message Box("communication error") but I got the same unmanaged exception.

By the way I. My application I have one Mainform with one EtherntIPCLXCom drive and several popup forms with the basic buttons and their own EthenetIPCLXCom drives pointing in some cases the same address.

[Archie]

Go to Debug->Windows->Exception Setings (or Ctrl+Alt=E)
In the Exception Settings windows, right click Common Language Runtime Exceptions and select Restore Defaults

Thanks for you answer Archi, I reset the exception strings but jus now I got the same error:

Sistem.ObjectDisposedException: Safe handle has been closed

Are you hiding or closing the popup forms? It looks like something is getting disposed some where and I will guess the popups are being closed which will dispose of the driver. Does your BasicButton also close the form?

[Bvillalobos]

Yes when  I the radnomized eception appear afther close the popup window, I normally close this windows with one Visual Basic button or with the standart windows close icon.

[Archie]

Can you do a hide instead of close? Or maybe set the MinimumHoldTime to 0

What I suspect is happening is the button writes a 1 to the PLC, next the form is closed, then after the MinimumHoldTime, the driver tries to write a 0 to the PLC, but it has already started the dispose process.

[Bvillalobos]

Ok Archie I will do it, by te way I just tested with the bin file out of VB Studio and change the type of button to Momentary Button with the same result

[Bvillalobos]

Hi Archie I hided All the popup windows and it look like the problem disappear !, thanks, nice support we are planing to use AHMI in industrial projects, we are going to evaluate you Hardware to do that.

[Bvillalobos]

Yes!! The exception goes !!! Thank

[Godra]

If the exception still goes then you should consider redesigning your project and abandon the way you are doing things right now.

[Bvillalobos]

Thanks Godra for your advising but until I change Me.close () by Me.Hide() in the Popup windows everythings it Ok !!
