System Variables

[skippynz]

Does anyone know if there is a way to set a systemwide variable using autoit ? i know you can get the variables by useing envget but how can you set it so other programs outside of autoit can use that variable. ???

any help is appreciated.

cheers

EnvSet()

from the helpfile:

A environment variable set in this way will only be accessible to programs that AutoIt spawns (Run, RunWait). Once AutoIt closes, the variables will cease to exist.

i know about envset() but those disappear when autoit closes. i want to use my script to set a variable that will stay when the script has finished.

The only way to do this is to ClipPut() it and then Clip

Get() it (or equivalent command) from the other script....

hmm would love too. but the idea is to check what type of machine is running, so that at a later date i can just pull that info out of a system variable

ie we have tecra 8100 - 9100 - m1 - m2 and m3 notebooks, each require a different setting for the power save utils. so i need to call that variable to choose what registry settings the machine will get to turn off hibernate and standby modes etc...

Maybe if you used IniRead() and IniWrite() do the trick?Use the ini file as a long time variable....

guess that might just have to do if you can do system wide enviroment variables

Write to the Registry. Try this:

RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment", "XXX111YYY222ZZZ", "REG_SZ", "THIS WRITES A SYSTEM VARIABLE")

I haven't played with this enough to know when they become available, but to permanently, but you can write environment variables directly to the registry.

To set a USER environment variables, use:

RegWrite ( "HKEY_CURRENT_USER\Environment", "VariableName", "REG_SZ", "VariableValue" )

To set a System (global) variable, use:

RegWrite ( "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment", "VariableName", "REG_SZ", "VariableValue" )

Being a command line junkie, any system I use regularly has:

RegWrite ( "HKEY_CURRENT_USER\Environment", "Desktop", "REG_EXPAND_SZ", "%USERPROFILE%\Desktop" )
RegWrite ( "HKEY_CURRENT_USER\Environment", "MyDocs", "REG_EXPAND_SZ", "%USERPROFILE%\My Documents" )

so that from a command prompt I can type

CD %desktop%

to change to my Desktop directory, and likewise to My Documents.

Try using EnvUpdate ( )

Similar effect as logging off and then on again

I used it on my BartPe to set TARGET_ROOT so I can used the tools for ERD commander.

EnvSet("TARGET_ROOT", "C:\Windows")

EnvUpdate()
