Hi,
I am using Open Office 3.0 and Netbeans 6.5 for my development. I want to use 
Open Office as my DDE client. I already have a DDE server application. I start 
the server and write the DDE formulas on the OO calc spread sheet using 
XCell.setFormula method.
When i use the DDE server with Open Office, i found that when i write the DDE 
formula on Open Office cell by programming the topic first get registered and 
then after first Advise the topic get disconnected but when i just open the 
Open Office spread sheet and paste the formula when server is already start, 
its works fine.
 
the sequence of functions calls is as follow 
by writing the formula with the application program(XCell.setFormula):
1. onRequest
2. onAdvise
3. onDiscnnect
 
by running the Server and writing the formula by hand
1. onRequest
2 onAdvise
..........
..........
its continue get updated until the topic is deleted and after deleting the topic
3. onDiscnnect

I don’t understand this behaviour of OO. The same thing works fine with MS 
Excel.
Please reply as soon as possible.
