Passing data to another AMS application at runtime

[telco]

No, MemoryEx was designed for the Indigorose implementation of Lua. LuaJIT does have the FFI library, you can use that to achieve the same: http://luajit.org/ext_ffi.html, but it's a bit more work. You need to know the Windows API for that, as you'll have to implement the subclassing as well.

Yeah this was really my problem, because remember last year i have a project really need ffi for playing audio on another soundcard so i used luajit to make it work,, now i found your example (CustomeWindowMessage) is very useful also but when i used MemoryEx with luajit my application doesnt work nor no window appear when try to publish or run.

I will check if my knowledge can do the rework since you mention its a bit more work.

Here is a quick example using SendMessage with the WM_COPYDATA message to communicate between AMS processes using MemoryEx. This example is a 10 minute rudimentary, but try it out and look at the MSDN docs for SendMessage, PostMessage, WM_COPYDATA and MemoryEx docs on MemoryEx.AllocateEx, MemoryEx.TableRequiredSize, MemoryEx.Table.

Attached you will find a Sender and Receiver project

Sender

• Globals
• On Click on each button

Receiver

• Globals
• On Show (adding a callback for the WM_COPYDATA message)
• On Close (removing the callback, important!)

Hello ip, thanks for this example very light and it works, my project is to send message or command to other application like creating a small application video player for my baby, but i have a problem, i am using luajit and not the usual lua 5.1 then if i enable the memoryEx plugin my application wont run.

Any possible solution?
Thank you for sharing the example.

Hi IP, is there any example using memoryEx sending message to other ams application?

Are you talking about a Window message, or are you talking about communication between programs? The examples you quoted show the latter.

[telco]

The "MemoryEx - Tables and SharedMemory" examples in the Examples directory of the MemoryEx download also display two examples that make inter-process communication possible.

Imagine Programming thanks, I'll have a look at that too

Excellent, will have a look at those.
Thanks v much, colc

Hi Derek ,
Found these 2 in my achives.The video one was named videoremote1 & 2 where you compile videoremote2 and insert into videoremote1 docs folder.
The send message just sends a number to the child windows created.You can create as many as you like.
Hope this helps.

I'm looking at having two AMS runtime applications running at the same time, to display different things. App 1 is to pass info to App 2 to display it.
This is not something I've needed before, and I remember there was an example posted some time ago (like a few years ago!), but in searching, I can't find it.

Anyone done this and would be kind enough to give me some pointers?
