ActiveX server are slow

[KaBooOoom]

Hi !

I have a problem, and i hope someone can help me...
I have an application which write 240 values in a table every 100ms. I want to read some of these value from an external application (VB or Labview). In order to do this, I use an active X server (the application whiwh write the values) and a client (the application which read the values). That's work perfectly!

My problem is the following: It's really slow, if i read more than 30 values in 100 ms my CPU works at 100 % !! I think that's come from the active X mechanism, is there something i can do to improve my program, or should i use another technologie ??? What are the others solutions.. i think dlls will not run faster ...

Thank's for your advices !!!

Hello,

If you have the same problem with LabVIEW or VB, the ActiveX client is not the reason of the problem.
What is this ActiveX server ?
Could you also send the LabVIEW program and the LabVIEW version ?

Hi Marc !

At first thanks a lot for your answer ...

I found a method in order to improve the performance of my program. Before, in order to get 30 values, i called 30 times the method getControlValue, that was really slow... Now, i make only one call with a array of parameters to get or to set, and that works perfectly! I think that's the solution, you have to minimize the active X call !

Bye !
