dynamic images that reside on a local server

VLCNCRZR

Does anyone know if it is possible to link a dynamic image window on a G4 panel to a PNG or JPG graphic file that resides on a local server rather than a website based graphic image??

Thanks.

Yeah I've put images on the Master itself for an aplication. You just use the address of the Master then instead of the Web address, ie 192.168.1.1

I also use the local drive for storing and displaying images. You may want to consider using the IP_ADDRESS_STRUCT if you don?t want to hardcode the IP address of your master into your program or into your touch panel file dynamic images.

DEFINE_VARIABLE

IP_ADDRESS_STRUCT sNetlinx

DEFINE_START

GET_IP_ADDRESS(0:0:0,sNetlinx)

And then in your code you can use sNetlinx.IPADDRESS as the IP address of the master.

NI master vs. local server

I've got the NI master method down, but I would like give the client the ability to update a specific image on his server rather than logging into the master.

The NI master has an FTP server, which make this process easier.

Would this be a matter of just opening the necessary FTP ports on their server. Other than FTP or HTTP, I dont know of any method to direct the dynamic image to the panel. Maybe AMX will develop a general directory entry for this type of application of dynamic images.

I can do a G4 Computer Control window with no problem to the server,
but cannot get to a single specific graphic file. I realize the G4CC does not utilize the FTP protocol for communication, so this is probably not a good comparison.

Thanks for your replies.

Sorry, I misunderstood the original question. My mind lives inside Netlinx.

This may be a stupid idea but you could install a lite web server on the local server and store the images there. Maybe someone else can come up with something better.

Yep - it's time to get your client to run a web service on that machine... FTP and HTTP are your only options from AMX-land, so that's what needs to be on the other end of the call...

image problem solved!

I just downloaded and tested the AMX PictureFrame application and it will work perfectly for this particular project.

I rememer seeing this on the AMX web site a few years ago, but thought I would never utilize this type of program.

Unfortunately, it took me a few hours to remember that it existed, and where to find it.

Thanks again for the suggestions.
