Registers an external DLL and its exported functions callback with Visual CADD™, enabling messages to be sent back to the application when the specified events have occurred. This call is the same as VCSetAlertAppDll, except that with the addition of a second iCode parameter (iCode1), it can handle a larger range of alert codes.

extern "C" void WINAPI VCSetAlertAppDllEx(short* iError, char* DllName, char* NativeCmd, long iCode0, long iCode1);

procedure VCSetAlertAppDllEx (var iError: Smallint; DllName: PAnsiChar; NativeCmd: PAnsiChar; iCode0: Longint; iCode1: Longint); stdcall;

Sub SetAlertAppDllEx(ByVal DllName As String, ByVal NativeCmd As String, ByVal iCode0 As Long, ByVal iCode1 As Long)

iError -
0: success
1: failed - An AlertApp with the same DllName and NativeCmd parameters is already set .

DllName - The name of the external DLL to receive the callback messages. If the DLL does not reside in the same directory as the Visual CADD™ DLLs, a path needs to be included.

NativeCmd - The name which prefixes the function names in the exported callbacks functions defined in the external DLL.

iCode0 - Specifies the alerts the external application wants to be notified of. This parameter can be a combination of the iCode0 flags specified in Alert Callbacks. If you do not want to be notified of any iCode0 events set the iCode0 flag to ALERT_APP_NONE.

iCode1 - Specifies the extended alerts the external application wants to be notified of. This parameter can be a combination of the iCode1 flags specified in Alert Callbacks. If you do not want to be notified of any iCode1 events set the iCode1 flag to 0.

VCSetAlertAppDllEx is used by a DLL to request notification (alerts) of certain events in Visual CADD™. The notifications take the form of callbacks to functions exported from the DLL. This approach is significantly more efficient than the messaging used by VCSetAlertApp and VCSetAlertAppEx.
