I have created a music player that is yet to function to its full ( the add button on my main form1 won't bring up the AddNewWaveTrack_form ).

These errors vary so any help is much appreciated as I want to learn fast.

Try searching for an open source player written in C++. I've found this to be useful when writing code. Have you read through all the errors yourself? Double check your errors and make a list of the ones you cant fix. A few seem fairly simple to fix.
Happy coding,
