Put all your data in one plot and make those invisible which are not relevant at the moment.

Use transparent colour for this purpose. See  :camera:

Is there a way to make a slider control return to the default position when released?

The aim is to have a control which acts like the accelerator of a car.

When released, it will spring back to 0.

Thanks

Hi,

If you use a Event structer associate with your slider, i think you can do that. Use the mouse up event. i hope this example can help you.

Hello,

How i can associate one key to a button, i have seen all examples but i did't find anything, i saw the properties of buttons and nothing, anyone can help me please :headbang:

I assume you want to selectively monitor controls? For example, sometimes you look for a value change and sometimes you ignore it?

Yes, it's monitor controls, but i found the rude way and that is ok. It is disapearing the controls, if is not visible you can change it. , i wanted block controls without invisible their, but it's ok

Thanks

Hello!!!

I'm using a Event Structure in my application and i use the value change event in some of my controls. I'm trying to do is ignore same control events when i want. If i select the "Application Exit?" event there are an element for i discard that event but in "value change" event that element is not there.

There are any chance to block the controls?

Best regards

Paulo Almeida

Congratulations :thumbup:

Sorry folks,

I resolve that problem, it's an rude way but for i need it's very good. i use the example of lv and in output, which is array i put a index array and it give me one point.

forgive me anything.

Bye

Hello,

I'm trying to do a Arbitray wave display, there are a example in LV examples. but in this case the output is array and i need a think who generate a wave form point by point. the lv doesn''t have this function as it have arbitrary wave.

Someone can help me

Bye

Okay, I hope this helps -  I haven't spent a lot of time on it, so I am sorry if I have missed something - let me know.

I found one think and i don't to know how to resolve, in your date server handler you receive all queue at period of 500ms, but in this case, when passed some time you send a string for tcp which incresed too, and the date transfer go for hell

i put the dequeue element and the queue works well for only one client, when i put two clients the receive string in client pass for half, but it's logic

how can i send one element for clients but not erase the queue and not nedd pause the while loop. :headbang:

Hello,

One more doubt for everbody.....

In the application made by Michael Aivaliotis

niweek2004

There any way for i know how many clients are connected in the server?

Hello

Yes, that me help, help me a lot, thanks :worship:

Your Number generator will be my server. but i having a douth . i 'm trying to do a client supervisor in my server for manager who command the process in server and other thinks able to do in that. my douth is where i put my supervisor, if in my server or if in dateserverhandler.

In relation of the queue, it's a good ideia. but i won't to send all information for all clients. I want to send the information for a client since he arrived not since the server runned. I think if i create a queue for all clients connected, when they arrive i clean that queue and send only present information. but i'd studied more in that. :headbang:

Thanks for all

I've worked in that application, mainly in the Example4 - Reentrant_example_tcpip_connections and like that. But server don't send anything for his clients. the time which is sending is on the DateServerHandler and the user can't controller. How can i put a string control in a server and type anything and send for all clients

I'd seem all methods of invoke node and i only can view things for set controls, there are any thing gor get indicatores of vi handler.?

i think i'll go for :beer: and forget LV

The best regards

Hello Again

I pass this afternoon watch your application, and i repair in a vi BabVIEW_Log.vi and you don't use that or i haven't seen in use. that is rigth?

I understand more the Notifier Operations Functions, your application help me. I'll use that in my application

Best regards

Keeping in good work

Paulo Almeida

Hello

I'd analyses your application... and it's fantastic, you perceive a lot of Labview. i passed several hours to unde rstand your application and don't understand lots of thinks.

I don't understand i you use wait on notification, i never use those tools and don't know for that they serve but i'll read the help. one more douth if i want run other apllication in server how can i send the results of that application for all server? i think in your server you are able to write messages for all clients.

I'm putting my application in here for people test

It would appear an error at the end of simulation if you don't have a matlab

Hello,

I don't know the details of your application, but based on the fact that you have one server and many clients, and the fact that you want to keep all data,

My application is based in a server and multiple clients but those clients have different types. There are clients who only wants to view the results of server and there are clients who wants control the application of that server, but server makes what it wants, view or controller.

I am thinking that you are using your DAQ vi as a data logger and the client vi's as remote analysis tools(?).  If this is the case, perhaps you should use an SQL database.  The DAQ vi would insert the data to the database, and the client apps would pull from the database.

your ideia of DAQ it's good but i must use other tool, MATLAB(restritions of my supervisor), for the clients analysis the receive data. I have two options:

1

Hey Paulo,

Another suggestion might be to use DataSockets.  Your server is a datasocket writer, and your clients are datasocket readers.  DataSockets are abstract enough that you don't have to worry about handling multiple connections - you just subscribe to the url of the data source and read when ready (or read, waiting for data).  See LV examples.

If you like the TCP/IP approach, then I believe Jean-Pierre's suggestions are best.

Cheers,

James

Hello

Yes the DataSockets it's a good option but i need receive all samples of server in all clients and datasocket it is a connection loose, or something that. And if i loose any data of server the clients will make calculation bad.

Thanks and the best regards

Dear James

I am devoloping a project with a server and multiple clients, with base on exemple of LV, but i am acquiring data in DAQ board in other while loop. but i want to send all information in that while loop for all clients,that data are in a array and i want to send it when it have a number of elements and repeat this operation several times.

I hope you understand that, my english is not very good

best regards

Hi,

One more topic for nobody reply.

I have a array which i want to send by tcpip. that array is building in a independetly while loop and i have other while loop to send information by tcpip. i use a local property to transport information of one loop to other. but i only want to send by tcpip, the information of array when it have one number of elements.

help me please

How can you put that TCP refnum? when i put a refnum in my LV the icon is different and the control appear in front panel. I don't know can you do it

Hmm....I see what you mean..  

You can write and read windows title name use the Open Application Referenceand  and Property Node.

try again.... :thumbup:
