(1) compilation errors are caused by incorrect code writing, such as illegal and actual use or lack of key codes, missing parameters or mismatched brackets. Other errors caused by undeclared variables, etc. VB generally reports an error when the code is written or run, and finds and solves it according to the error prompt.
(2) Run-time errors refer to the failure of the application to perform illegal operations or certain operations during the running process, such as the file to be opened cannot be found, the disk space is insufficient, and the divisor in the division operation is 0.
