The Morse Code Translator is for a school project. I'm fairly inexperienced with coding. I'll try to explain the program the best I can.

There are 2 Textboxes and 1 Button. Input a character, word or sentence into TextBox1, Click the Translate Button, and then TextBox2 will show those characters in Morse Code.

The button also plays Audio from my resources. (If I type A and click the button, a 'dit + dah' (.-) will play)
The button also flashes a picturebox with an image of a light that corresponds to the dits and dahs.

The Problem

When there are 2 or more characters entered, only the audio for the last letter plays. (Type CAT, only audio for T plays)

I countered this by using WaitToComplete instead of Background

My.Computer.Audio.Play(My.Resources.MorseA, _
AudioPlayMode.WaitToComplete)


And it worked, it played the audio for C, A then T. BUT WaitToComplete stops executing code, and now my pictureboxes won't flash. I've tried using timers and progressbars, but I'm really struggling to get it right.

Is there a way to play the audio files sequentially, without stopping the code from executing, allowing the pictureboxes to flash with the audio?

This is probably not a great explanation, but please do ask questions if you don't understand something. And thanks in advance for the help!
