' Example of the CWAVMID Class ' ' To try this example, do the following: ' 1. Create a new form ' 2. Add a command button called 'cmdPlay' ' 3. Add a command button called 'cmdStop' ' 4. Add a command button called 'cmdPause' ' 5. Add a command button called 'cmdRewind' ' 6. Add a command button called 'cmdRecord' ' 7. Paste all the code from this example to the new form's module ' 8. Run the form ' This example assumes that the sample files are located in the folder named by the following constant.
