Error Codes

The error codes are values that identify different types of errors in the Windows API. Most functions do not report the error code directly; instead, they simply return a flag specifying if some error occured or not. The actual error code can usually be obtained by using the GetLastError function.

The following list identifies various error codes defined in the Windows API. Your application may define its own error codes and use them with the error functions. However, make sure that bit 29 (&H20000000) is set in any application-defined error code you define. Because no Windows API-defined error code has that bit set, using that bit assures that your error code will not conflict with an existing one.
