[aus-dotnet] WPF UI Thread

[Stephen Price]

Hi all,

 

I've got a WPF problem I'm trying to work around.

 

I want to display a progress indicator, and have a control with a funky little animated thing on it, but the function I want to display the indicator during blocks the UI thread.

I tried putting an application.doevents() in after my indicator is called and it does show it but it doesnt animate. Dont have the code handy but the psudocode goes like;

 

displayProgress();

view.Print();

clearProgress();

 

with the result of the progress indicator being shown then cleared immediately so that you dont see it. (remove the clearProgress and it is shown after the print finishes.)

 

I think it's the way the view.Print is written... I tried it on its own thread but it seems to want objects in the UI (Its printing a listview).

 

thanks,

Stephen
