Chapter 4 ActiveX Client Interfaces
| Type library name | JaguarTypeLibrary |
| DLL name | jagproxy.dll |
Defines symbolic constants to errors that can occur in the ActiveX client proxy.
Table 4-2 lists the codes for client-side error numbers defined in the JagORBClientErrNum enumeration:

| jagClRetValSetErr | 8024 | An error was encountered while updating the return value for amethod. |
| jagClRecsetArgErr | 8025 | The ResultSet type cannot be passed as a parameter in either the input or input-output modes by a EAServer ActiveX application. |
| jagClUnsuppTypeErr | 8026 | An unsupported OLE Automation type was used as a parameter in a method. |
| jagClAxConvertErr | 8027 | An error was encountered while converting a input-output method parameter received from the server. |
| jagClJagConvertErr | 8028 | An error was encountered while converting a input parameter prior to method invocation. |
| jagClNoInitErr | 8029 | A component instance must be created prior to invoking a method. |
| jagClRecordsetCreateErr | 8030 | An internal error was encountered while creating the Recordset object. |
| jagClRecordsetMoveErr | 8031 | Attempt to call MoveNext on a RecordSet which has its EOF property as TRUE. |

| jagClInvalidIntfErr | 8035 | The fully scoped interface name passed as an argument to the Narrow_ method is invalid. |
| jagClOrbInitErr | 8036 | An internal error was encountered while initializing client-side ORB. |
| jagClOrbStrToObjErr | 8037 | An internal error was encountered while invoking the ORB.string_to_object method. |
| jagClNotJagCollErr | 8038 | he parameter of the sequence type passed to the method is not a valid EAServer ActiveX Collection Object. |
| jagClInternalCollErr | 8039 | A fatal internal error occured while performing an operation on aEAServer Collection object. |
| jagClAxSSLCBRegErr | 8040 | A fatal internal error occured while registering user's ActiveX SSL Callback component. Verify that the directory containing the file jagproxy.dll is in the PATH. |
| jagClDuplicAxSSLCBCompErr | 8041 | The "AXSSLCBComponent" ORB property cannot be set more than once per session. An ActiveX SSL Callback component with a ProgID of progid has previously been registered for the present client session. |
In Visual Basic, exceptions are mapped to the built-in Err object. The exception number maps to Err.Number and the description is available as Err.Description. You can handle exceptions by activating error handling code with On Error Goto statement or by checking whether Err.Number is > 0.
The proxy type library defines error numbers for client-side errors in the JagORBClientErrNum enumeration and server-side error numbers in the JagORBSrvErrNum enumeration.
