Funcionalidades de GeneXus que conviene conocer: ConfigurationManager external object
El external object ConfigurationManager, viene nativo en el modulo GeneXus.
Msg(ConfigurationManager.GetValue("DateFormat"),status)
endif
Ademas la solucion GeneXus se puede pasar de .NET a Java sin tener que hacer adaptaciones, quedando mejor situada para ser multiplataforma.
The ConfigurationManager external object allows you to read the application configuration at runtime.
This means that you have a way to access the configuration that is being used at runtime and has been set in environment variables (only the variables explained in this document) or configuration files (a.k.a. web.config, client.cfg., CloudServices.config).
Methods
HasValue
Returns true if the property has a value set.
The parameter filename is optional. If it is not set, a valid property is one that is set in the standard configuration files (web.config / client.cfg or CloudServices.config) or an environment variable.
| Return value | Boolean data type |
| Parameters | propName:VarChar [ fileName:VarChar ] |
GetValue
Returns the value set in the property.
The parameter filename is optional. If it is not set, the property must be one that is set in the standard configuration files (web.config / client.cfg or CloudServices.config) or an environment variable.
Notes
In both methods, the name of the property is instantiated as it is in the web.config or client.cfg. If you require a property of another file, either from the CloudServices.config file or from your own, the name of the property must be prefixed with the service type separated by a colon (:). eg: Notifications: APP_ID.
If a file is specified, the format of this file must be similar to the CloudServices.config and the way to choose the value of a property is the same as in the case of the CloudServices.config (<ServiceType>:<propName>)
As of GeneXus 16 Upgrade 7, services from the same type can appear more than once. That's the case of the Chatbot type where every property is saved under a Chatbot instance identified by the Conversational Flows name. So in that case you should get the property with the following format <ServiceType>:<ServiceName>:<propName>,
Sample Configuration file:
<?xml version="1.0" encoding="utf-8"?> <Services> <Service> <Name>MyServiceName</Name> <Type>MyServiceType</Type> <ClassName>MyServiceClass</ClassName> <Properties> <Property> <Name>Property1</Name> <Value>Value of Property 1</Value> </Property> <Property> <Name>Property2</Name> <Value>Value of Property 2</Value> </Property> </Properties> </Service> </Services>
To get the value of Property1, write the following:
&FileName = !"MyConfigFile.config" &propName = !"MyServiceType:Property1" if ConfigurationManager.HasValue(&propName, &FileName) msg(ConfigurationManager.GetValue(&propName, &FileName)) else msg("Property has not been set") endif
Availability
Configuration Manager is available as of GeneXus 15 upgrade 12.
