Avoid calling Invoke when the control is disposed

Question

I have the following code in my worker thread (ImageListView below is derived from Control):

if (mImageListView != null &&          


        

Answer 1

One way might be to call the method itself ones more instead of invoking the ImageListView-Method:

if (mImageListView != null && 
    mImageListView.IsHandleCreated &&
    !mImageListView.IsDisposed)
{
    if (mImageListView.InvokeRequired)
        mImageListView.Invoke(new YourDelegate(thisMethod));
    else
        mImageListView.RefreshInternal();
}

That way it would check one more time before finally calling RefreshInternal().
