My custom C# userInterface hangs/locks when trying to launch parallel sequences ...

[manu.NET]

Hi all,

I have build my own TestStand userInterface in C# this way :

• One main form which contains the axApplicationManager
• N tabpages containing each
• One axSequenceViewManager
• One axExecutionViewManager
• My process model is "Sequential process model"

The aim of this architecture is to be abble to launch multiple sequences in parallel, one on each tabPage.

On each tabPage i have to run a different sequence, and i force the main sequence parameters before launching them.

My application works sometimes well, but sometimes it hangs completely ! 

When i launch the sequences in a sequential way, there is no problem.  (Sequence 1 executes on tabpage1, after completion i launch the sequence 2 on tabpage2 ... and so on ... )

I have tryed to "Mutex" (using a lock on a static object) the AxObjects access (Calls, events ... )

=> But it still hangs !!!! 

Does parallel userInterfaces examples exists somewhere ? (In C# or VB.net)

I have read in the online help that using "UIEvents" in C# must be followed by an acknoledge call !! This made my application hangs directly !

I have also put a timer on my main form, in order to call the garbage collector every 500ms.

I also force all Teststand object references to NULL after each use.

Have you some ideas ?
