SetUpDDEHotLink()

[Joycezh]

Hi,

I am using LabWindows/CVI as a DDE client and I have other DDE server. I want to read the data from the server and show the data in the user interface.

Basic flow I did is like the following:
-----------------------------------
SetUpDDEHotLink()
ClientDDERead()
SetCtrlValue()
------------------------------------

But the problem is that it shows the current value in the user interface and it won't update when the data changes. How can I make the data updated dynamically according to the data in the server?

Thanks,
Joyce

Hi Joyce,

Hope you had a good weekend!  Typically when you are want to refresh your user interface, you would use GetUserEvents or RunUserInterace.  If you are using a processor intensive application, you could look into using ProcessDrawEvents.  I hope this helps!
