R – Changing font values from PT to PX in Flash CS4

Maybe the problem was like this:

Your original movieclip: 'originalMC' The call upon actionscript in the movieclip: 'originalMC.someRandomFunction()'

If you rename your movieclip in the Flash IDE the call wont work.

Otherwise I have to say that your statement is very vague. If you maybe could show an example of your code. I don't understand "but I couldn't get to the script anywhere in the Flash CS4 UI".

OH ... I think I do understand now. If you have actionscript inside of a movieclip, as it is common in as1 & as2, that code can easily vanish if you change type of the movieclip or even if you rename it.

What the hell am I talking ...

The simplest way is an anonymous method passed into Label.Invoke:

// Running on the worker thread
string newText = "abc";
form.Label.Invoke((MethodInvoker)delegate {
    // Running on the UI thread
    form.Label.Text = newText;
});
// Back on the worker thread

Notice that Invoke blocks execution until it completes--this is synchronous code. The question doesn't ask about asynchronous code, but there is lots of content on Stack Overflow about writing asynchronous code when you want to learn about it.
