Forcing MATLAB to wait for an external program to finish a DDE command
I have a MATLAB script that calls an external program via DDE protocol, I want MATLAB to wait for the execution to end, which is indicated with a 0/1 that is returned from ddeexec(programName,command).
I had no success trying to use wait or waitfor since they receive an object and I only have a returned value (which is a double).
The temporary solution I have is to use pause(secToPause) but it's not a good solution as the external program run time can change.
Note that the external program is always running in the background so checking if the process had finished won't work either.
Any suggestions?
osloFinished = 0; %set var to see if OSLO finished its job
osloFinished = ddeexec(OSLO,osloCommand); %send execution to OSLO
matlabMagicWait %here I want to matlab to stop and wait for osloFinished to change to 1
matlab wait pause dde

You didn't indicate what app you are using DDE to communicate with. Does the app have a COM/ActiveX interface that could be used instead of DDE? DDE is very old and the recommended method is to use COM instead. Sorry if this is not of help to you.

The app is called OSLO and sadly it is the reason I have to use DDE.

If there is a command that finishes quickly, you can send this repeatedly and wait for it too succeed.wait(1)or so in between sending the commands.
