How to filter messages on MCB2300 CAN?

I have an app that gives me that a stack overflow error too CAN traffic.  I only need to follow a single message, and if I have only one message on the bus, it works well.  As soon as I add the other messages on the bus, I get the error, so I thought I could just remove the ones I haven't read wan't.  I put the filter in my code, but I always get a stack overflow when all messages are broadcast.  How the filter works  The messages go to battery memory first until a software routine has time to cross and filter unwanted messages?

The original request has 1 CAN channel without filtering, and 1 CAPABLE of channeling with filtering.  The order of the properties between the 2 CAN channels initialization was not specified in the code and was arbitrarily determined by the compiler.  I forced the CAN channel without the filter to initialize before the channel with the filter, and then it works properly.

  • How to filter messages simpleChat (private chat)

    So I tried to find a solution, but after several hours, I can not find how do.

    My use case:

    There is a single host for a room. Others in the room can speak to the host, and users can see their private chat with the host. Users can see the chat component only when the host is connected.

    The host uses another application in which he can see the list of users who speak of him. It can select a user from the list, and he sees a simple conversation with only messages between him and the selected user.

    What I finished (I think it may help others in the future and maybe, there is better way to do):

    * In the user application: use the userManager your ConnectSessionContainer property. There an arrayCollection named collection hostCollection on hosts that are currently connected.

    In my case, I put the components of cat in a container and use a link visible property:

    visible = "{connectSession.userManager.hostCollection.Length > 0} '"

    You can also add an event listener for the userManager and listen to UserEvent.USER_CREATE and USER_REMOVE and check if event.userDescriptor.role == 100 or again controlled the hostCollection.length of the userManager.

    * If you simpleClass of subclass, you can access the _toCombo which is the drop-down list of the chat area.

    You can set its visible to false and set its selectedItem property on the first object of its dataprovider whose role is equal to 100 in order to force the cat to be private with the host.

    * In the host application, you can create a list using the ConnectSessionContainer.userManager.audienceCollection as a dataProvider for a list of users.

    It is easy to set the combobox control to simple to talk only to the selected user conversation, but what I have not been able to do is to filter history to only show that the conversation with the selected user and no other messages, without creating several rooms.

    I looked in the source code, but the historic property of the simpleChatModel is just a string and do not find an easy way to filter.

    I was looking for an arrayCollection collection nodes in the history, because I could use the filter property of the collection, but I did not find.

    So, where should I look for, and what is the best way to filter history using the recipient_Id?

    Thank you for your help...

    Sorry for the long post, but maybe this will help someone in the future...

    Hello

    What other parts you have been doing is perfectly fine. So, I think on

    on the side of the host you want to filter so that when a host, you select one

    user and click on it, it should show only chat between this user and

    the host.

    Although there is no direct way that by default, show us all messages to the

    realized a user cat, but again I can give some advice.

    What you need to do is change the method of formatMessageDescriptor

    SimpleChatDescriptor or subsclass it.

    Try to maybe add another parameter to this function as

    public void

    formatMessageDescriptor(p_msgDesc:ChatMessageDescriptor,p_targetedUserID:String=null):Stri ng

    and when you create an object of SimpleChat, ensure that in calls to

    This method, you pass somehow user ID only the user that you want to

    See messages with. In a more general way, this setting may take a

    array that contains only users whose desired cat IDs

    for display in a window.

    Inside the function, make sure that filter you to do something

    Like this

    If (p_msgDesc.recipientID == p_targetedUserID) {}

    you would add these messages

    } else {}

    do nothing to make the message back «»

    }

    If you use a table of targetedUserIDs, then a check of the loop if

    He allied himself with the recipientID and if so, adds this message.

    It should work in your case. We are planning a complete overhaul of cat

    in the future (period of next year), at that time there I'll definitely keep

    your suggestion of the spirit.

    Let me know if it works for you.

    Thank you

  • To use the same filter messages on multiple computers

    I have three computers running thunderbird at different places in the world. I am using IMAP so I have all the emails anywhere. Now, I would like to run the same filter message on any one of them, but I can't export/import the message filter as I have copies of my filter. What should I do?

    I found the file differently as you indicated.
    There is no account option that you made on the Tools menu of thunderbird.
    However choose the localfolders file, you can select accountsettting. There's the localfolder displayed directory.
    Now, I see also the otherway. In the menu choose options (tools not), you can select the account settings and then select in this local folder menu and it displays the local directory as in the other method.
    The rest is as you said, thanks.

    Sorry, I copied the 'msgFilterRules.dat' folder, but nothing has changed. In fact when I delete this folder Thunderbird still remember the filter rules. They must be somewhere else on my computer...

  • How to filter uploaded duplicate pictures in "Photos".

    How to filter uploaded duplicate pictures in "Photos" (in order to remove duplicates)...?

    Usually, Photos should you cannot import duplicates. It will give a warning if you try to import an exact replica.  You are importing different versions of the same photos?

    Photos has no tools to search for duplicates. You would need a third party program to analyze the library of Photos of duplicates.

    I can recommend these:

    • Pictures of power will detect duplicates, if the file attributes are the names of files, identical for example. See this link:

    https://www.fatcatsoftware.com/powerphotos/

    Independent detection of duplicates, it is a great tool to use in combination with pictures.

    • PhotosSweeper is very versatile for find duplicates in a different state of the edition or the size. It will detect cropped versions of the same photos, or reduced in size, as it will compare the photo, not only the attributes of the file: http://overmacs.com/photosweeper.html

  • Topology change syslog, how to disable messages?

    I have a number of switches BNT/Lenovo (8124, 8052, 8264) and all are connected to our central syslog server. I have quite a few switches in the same vlan, and I get a lot of topology messages of change like this:

    I don't necessarily need to see this. I would like to delete this message without Gohan other messages such as the STP root bridge changes. Is this possible? These seem to be my options from the side of the switch:

    or enable/disable syslog on all available functions.

    I know that I probably can filter messages from syslog server-side but I would rather start the level for the switch.

    Thank you.

    Today, there is no way to delete these specific messages.

    They should not be too many and are often very useful to determine the cause of a failure.

    In order to reduce drastically the TCN BPDU is to put all the host ports such as 'edge' or 'portfast '.

    This setting prevent BPDUS and messages production when a host disconnect or connect to the switch.

    Then, only the 'real' TCN is recorded and useful for diagnosis.
