Answer 1

You are changing the button3.Text property within the first if statement.
When the second if statement is tested it is true (both if statements are running with each button click when the Text property is “Pause”)

Use if, else to run one code block or another.

Use if, else if statements if you want a test to be run on the second code block also.

You should also take account of the possibility that neither of these cases is true.

if (button3.Text == "Pause")
{
    CommandString = "pause mp3file";
    mciSendString(CommandString, null, 0, 0);
    Status = true;
    button3.Text = "Resume";
}
else if(button3.Text == "Resume")
{   
    CommandString = "resume mp3file";
    mciSendString(CommandString, null, 0, 0);
    button3.Text = "Pause";
}
