Hi All,

I have a application that :
1. Reads data from database.
2. Write it to msword. I am using org.eclipse.swt.ole.win32.OleFrame for interacting with word. It requires a composite.

Both 1 & 2 are long running process. I need to show their progress. So when putting them in progress monitor bring 'Invalid thread access'.

After investigation it is found that interacting with word is a gui operation(uses a composite) and invoking it from a non-gui thread caused the exception.

I tried to use Display.asysn(xxx) & Display.sysn(xxx) method but even this didn't worked as 1 & 2 works in loop.

I even created a new display for the 2 process and dispose it once process is complete, but it works for the first time only. Running my application second time again gives 'invalid thread access'.

I am using draw2d for some drawing. So for the second time even the drawing is done incomplete.

Is there any solution for it ?

Thanks
Puneet

Try
workbench.getProgressService().runInUI()

Seemed fine, but the problem with the drawing part still persists.

I need to verify:
1. Creating a new display and disposing it from eclipse workbench is correct ?

Try to explain my code:
I am running my code in a thread that is passed as IRunnableWithProgress to PlatformUI.getWorkbench().getActiveWorkbenchWindow().run(tru e, false, thread) / PlatformUI.getWorkbench().getProgressService().busyCursorWhi le( thread);.

Following is done in:
Creating a new display object.
Creating a composite over new display for word automation.
After completing the process display is disposed.

At times it works fine. But occasionally bring SWTException on disposing display object and then all text from drawing editors disappears.

Plz comment

thanks
Puneet
