Delphi中如何用程序设置环境变量?

[Icebird]

我用过API函数SetEnvironmentVariable，但却没有成功，请问有没有更好的方法

[BCB]

可能设置的是局部的,一退出就没了

再次请教！

[Kingron]

设置SetEnvironmentVariable只是对当前进程起作用！SetEnvVariable才是全局的。

//faint，没有这个函数？

BOOL SetEnvVariable(LPSTR szName, LPSTR szValue, CMO cmo);

SetEnvVariable sets the specified environment variable to a certain value. The environment variable can also be elongated by specifying the command option flag fAppend or fPrepend. Under Windows NT, the environment variables affected are the ones specified in the registry. Under Windows 95, autoexec.bat is modified to set the values.

Arguments

szName

Specifies the name of the environment variable.

szValue

Specifies the new value that you want to associate with the environment variable.

cmo

Specifies the command option flag. You can use fOverwrite, fAppend, or fPrepend.

Return Value

If the function succeeds, it returns fTrue.
If the function fails, it returns fFalse.
