Project: Environment Variables Unit
Unit: PJEnvVars
Applies to: ~>3.0
⚠️ This component is deprecated and is retained for backward compatibility only. New code should use the TPJEnvironmentVars static class instead.
TPJEnvVars provides access to the environment variables in the current process’ environment block. Environment variables can be read, created, updated or deleted. The names of all available environment variables can also be enumerated.
Only one instance of a TPJEnvVars component can be placed on any form or frame. An attempt to create duplicate instances on a form causes an exception to be raised.
| Method | Description |
|---|---|
| Create | Constructs an instance of the component. |
| DeleteVar | Deletes an environment variable. |
| EnumNames | Enumerates all environment variable names, passing each name to a callback method. |
| GetEnumerator | Creates an enumerator that can be used to enumerate all environment variable names. On Delphi 2005 and later this enumerator enables the component to be used for..in loops. |
| Property | Description |
|---|---|
| Count | Returns the number of available environment variables. |
| Values | Provides read / write access to environment variables. |
TPJEnvVars exposes no events.
