How to use this event

Previous pageReturn to chapter overviewNext page   

Caution: this is old EurekaLog 6 documentation. This is not the latest version.

 

EurekaLog includes a "CustomDataRequest" event for interaction with the user program when a raised exception is handled by EurekaLog and the user want add some custom information to the Log text.

 

The syntax of this event is:

 

procedure MyCustomData(EurekaExceptionRecord: TEurekaExceptionRecordDataFields: TStrings);

 

Use the DataFields list to add all the needed values using the form "DataFields.Add('FieldName=FieldValue')".

 

To use this event you must create a routine with the indicated parameters and assign it to the CustomDataRequest EurekaLog variable, as shown in the following example:

 

uses ExceptionLog, ECore, ETypes; // The required units...

 

// This is a normal procedure (not a method)...

procedure MyCustomData(EurekaExceptionRecord: TEurekaExceptionRecord; DataFields: TStrings);

begin

   ...

   ...  // Your code...

   ...

end;

 

begin

   // Assign CustomDataRequest variable to MyCustomData procedure...

   CustomDataRequest := MyCustomData; 

end.

 

 

Note: to simplify management of your EurekaLog events, you can use the TEurekaLog.OnCustomDataRequest event.
