问题 From the dynamic form I added. I realized that I can't get a gif animation to run in the form's background. So I thought I'd give it a try by embeding a picturebox on the dynamic form, but it's not working hence why I'm here. So on my main form (Form1) I have 2 buttons, openfiledialog, and a picturebox. When you click button1 you browse for the an image to display in the picturebox, and when you press button2 as you can see from the code below. It'll open a new form, but what I want is to

问题 I’m making an audio synthesizer and I’m having issues figuring out what to use for audio playback. I’m using physics and math to calculate the source waveforms and then need to feed that waveform to something which can play it as sound. I need something that can 1) play the waveforms I calculate and 2) play multiple sounds simultaneously (like holding one key down on a piano while pressing other keys). I’ve done a fair bit of research into this and I can’t find something that does both of
