Cross-thread operation error with BackgroundWorker

[Tve]

Hi,

I am getting the 'Cross-thread operation error' when running a backgroundworker. I googled around and did a search here in the forum and I understand a trhead cannot write to another.

The thing is I do not want to write, but actually only read.

I want the backgroundworker to loop on a ListView and retreive displayed items, not write.

If I am doing something wrong, would somebody be kind enough to put me on the right track.

Hi Thierry,

The ListView lives within the UI thread. You cannot access this directly from any other thread or you will run into problems.

You can Invoke onto the UI thread from any otherthread - there's plenty examples of that in this forum. Post back if you're having problems.

Hope this helps,

Graeme

Graeme,

Thanks for your answer. I had kept searching and I found indeed the Invoke. I used this article:
