EAppType Unit

Previous pageReturn to chapter overviewNext page   

General support unit for application type concept (low-level).





This is low-level unit. Do not use this unit unless you need to extend or alter EurekaLog behavior.


Examples of application's type are: VCL, CLX, VCLX, console, service, CGI, IntraWeb and so on.


An application type is arbitrary non-empty string.


Application may have more than one type in some cases. For example, it can be both console and CGI.


Application type is generic qualifier that affects EurekaLog behaviour. For example, VCL application intercepts Application.ShowException and uses window error dialog.


This unit also provides a basic support for error messages, based on application type. For example, console application will write message to console and VCL application will show error message in dialog box.



If you modify this unit, consider the following guidelines:

Do not add additional unit into uses clause.
Do not add initialization/finalization section.

If you must break the above rules - make sure that there is no memory allocation during startup!
