If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero.
Note This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation—factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.
DeleteForm can only delete form names that were added by using the AddForm function.
