Non-transparent labels - C# / C Sharp

Steve Barnett

I've got a form on which there is a picture box with a picture in it.

On top of that I place two labels and make their backgrounds transparent.
What I expect to see is the picture showing through behind the labels, but
what I actually get is the background of the labels painted in the
background colour of the form.

Can I have "transparen t" labels over a picture box? I've done this many
times in my VB days and don't see why it should be a problem in C#, other
than the fact that I must be missing something fundamental here.

Thanks
Steve

Steve,

You can try to specify the picture box as the parent for these labels. I
remember I have seen something like this replied to a similar question in
these newsgroups. If this fails, do the Google Groups search - most likely
you're not the first to ask this question, and in all probability the
solution has already been posted by someone.

I did a quick search and found some potential solutions, none of which
seemed to work. In the end, I set the background of the form to the content
of the picture box and made the picture box invisible. That seemed to work
and will do for my purposes.

Thanks,

Steve

cast to non-const reference of a function's return object

hi, recently i discovered a memory leak in our code; after some investigation i could reduce it to the following problem: return objects of functions are handled as temporary objects, hence their dtor is called immediately and not at the end of the function. to be able to use return objects (to avoid copying) i often assign them to a const reference. now, casting a const return object from a function to a non-const reference to this...
