can I change master DDE inside DDE request.

I am using DDE's to communicate with server. The server then communicates with the hardware(ONCE).

Can i change master DDE.vi(clone):19..... I want to create delay in CIN of master dde.. or any change as i can not even debug or use probe

Hi timmy,

 

I'm not quite sure what you're trying to do here. Are you trying to edit the way the code interface node works internal to Labview? Also, why can't you debug or probe?

 

 

Cheers!

Thanks TJG...

I want to debug master dde inside DDE request vi. Because i want to see whats goining on inside master DDE and the parameters that are actually passing to CIN inside master dde. As its not properly working with hardware....

There is no option to debug or use probe inside master dde...is there any possibilty to do so

Hey Timmy,

 

Open up the VI, then go to File >> VI Properties, then select Execution from the listbox. Check the box that says allow debugging. You should be good to go!

Cheers!

You cant edit a reentrant clone, Hit ctl-M to get back to the original and edit it there.  Note that this will edit all other clones of the erentrant vi.  Also you can not probe reentrant clones on some older versions of LV

Thanks TJG and falkpl..

 Now i can debug and use probe inside clone vi.

I had upgraded the code from labview 4 to labview 8.5 and operating system from win 98 to win xp. And I had used porttalk software which make it working in XP. May be the new OS and labview timing is not matched with my hardware(ISA port). After using porttalk some commands are working well but some are not.

Is this is because of old reentrant clone dde vi. Can i upgrade or replace this dde clone

timmy,

 

Honestly, I am not really sure about communicating with an ISA port. According to the wiki page, they are pretty finicky with their settings... As for replacing the dde clone, I am not familiar with any method of doing so. Maybe somebody that knows a little bit more about DDE particulars can help you out a little bit more.

Cheers!
