poJsonObject Progress.Json.ObjectModel.JsonObject
The JsonObject to add the error details to
Top

PUBLIC CHARACTER DatasetErrorStrings (handle)
Purpose: Returns a single CHARACTER string composed of the error-strings
of all records (from all tables in the given Dataset instance)
Notes: Method moved to DatasetHelper, kept here for backwards compability
as a facade to DatasetHelper:DatasetErrorStrings

Parameters:
phDataset HANDLE
The handle of the dataset to return the error strings from
Returns CHARACTER
The string composed of the error-strings of all records
Top

PUBLIC DeRegisterErrorHandler (IErrorHandler)
Purpose: Deregisters the IErrorHandler implementation
Notes:

Parameters:
poErrorHandler Consultingwerk.Framework.IErrorHandler
The IErrorHandler to deregister
Top

PUBLIC CHARACTER ErrorTitle (Error)
Purpose: Returns the Title associated with an error message
Notes: Errors that implemnt the IErrorTitle interface return their own title
For other errors, when the SmartFramework is present the type name is
used as the message key when looking up translations in the "Error"
translation scope.
When no title could be obtained, a default title is returned from this
routine

Parameters:
poError Progress.Lang.Error
The reference to the error object
Returns CHARACTER
The title associated with the error message
Top

PUBLIC CHARACTER ErrorTypeName (Error)
Purpose: Returns the Typename of the error object
Notes: Required as .NET Exceptions don't have an ABL Class
(GetClass() returns ?)

Parameters:
e Progress.Lang.Error
The Error (Progress error of .NET Exception) to return the type name for
Returns CHARACTER
The type name (class name) of the error object
Top

PUBLIC CHARACTER FormattedErrorMessages (Error)

Top

PUBLIC CHARACTER FormattedErrorMessagesExt (Error)
Purpose: Returns a single CHARACTER string composed of the messages
Contained in the Progress.Lang.Error object, including the stack
trace and the text of inner exceptions when present
Notes: Useful when logging complex error objects to a file

Parameters:
poError Progress.Lang.Error
The Progress.Lang.Error to format
Returns CHARACTER
A string containing all formatted messages from the Error object
Top

PUBLIC CHARACTER GetRuntimeErrorMessage (integer)
Purpose: Returns the text of the given ABL error message

Returns CHARACTER
The error message string as returned by the IMessageProvider
Top

PROTECTED LOGICAL HandleError (Error)

will not display the error anymore, returns false when the
ErrorHelper should still display the error message dialog.

Parameters:
poError Progress.Lang.Error
The Error object to handle
Returns LOGICAL
Logical value indicating of the error has been completely handled by an IErrorHandler instance
