Using Emergence... does anyone know how to impement DDE connectivity between another windows application. I have a sample in VB, but I am unsure how to initiate a link in Emergence Basic. I read the MSDN articles about it. It seems pretty complex. Yet excel can do it without any programming, and VB seems pretty straight forward.
A VB sample is attached. It works if you use the MetaTrader 4 currency trading platform, and enable the DDE server.
It uses a linked text box which means the compiler inserts all the magic. I think.
How can we implement DDE connectivity?
(Paul: sorry to cross post from Priority Support. Didn't know if everybody looks there.)

Carl,
Didn't have an answer for you. Haven't used DDE since the win 3.1 days with C/C++. Depending on what you are trying to do I may have alternatives for you though. I have a group of applications that all register with a central monitoring application using registered window messages for example. For sending large amounts of data from one application to another there is the WM_COPYDATA message. And also COM automation if you are trying to implement an exposed interface to your program.
Paul.
Paul,
Well, all I need to do is fetch small amounts of real-time data (currency prices - open,high,low,close) from a trading platform that acts as a DDE server. (metaquotes.net)
P.S. I don't know if you remember me from way back (IBasic)... I didn't bug you much, but my investing software that I was programming made quite a hostile rukus on the old board. Fortunately for me, I didn't take their foul attitudes. My program is finally completed and a great success. I am moving on to other big projects. Thanks for your support (and time)... then and now.
