Hi!

I have written some functions for adding/removing directories from the search path of Windows. They work for NT (without restart) and 9x.

I will be happy to see them in the functions.html file or contrib folder so they can help others but me

Hi,

Some (possibly only older editors) can put EOF characters into the file, in which case the approach you use will fail (as your "SET" would never get executed).

Just a warning,
Dennis

Thanks Dennis!

After looking in the code again, I have found out that somehow some old code got into it. I have now attached the newest code from my installer script with (I hope) all of the corrections needed.

Please download this version instead of the earlier one.

About your comment, I don't really understand what you mean. Do these editors put EOF in the middle of the file? If so, how else can I seek for the EOF?

RefreshEnv

Hi,

Thanks for posting the path script. It would be helpful for me to get also the source for RefreshEnv or if you could explain what exactly it contains (Api call)

Greetings,
Andreas

Here is the API function called:

DWORD dwReturnValue;
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0, (LPARAM) "Environment", SMTO_ABORTIFHUNG, 5000, &dwReturnValue);

Kichik,

I have looked at your zip file and the archive example on sourgefourge. It is almost exactly what I am looking for. In both cases you change HKLU\Enviorment Path Key (which is for the logedon user). But in my case I want to append the path for all the users, HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\ Path key (As far as I know this is the right key). I have modified your code to change this key instead. It does append the path, but it seems to fix the %SystemRoot% to a string instead of a variable, eg (in dos)

Before addation:

path=c:\winnt\system\;c:\winnt\

After addition of c:\foo
path=%SystemRoot%;%SystemRoot%\system;c:\foo

Do you have any suggestions?

Thanks,

Ross

Use WriteRegExpandStr instead of WriteRegStr and it should keep the variables.

I am using Windows XP and when I uninstall everthing seems to work fine. When I check the path it looks ok, but when I try to type in commands that were accessible in my path I can't. Has anybody had this problem yet?

Lately i used this function:
http://nsis.sourceforge.net/Path_Manipulation

But i had to set timeout=1000 otherwise my explorer will crash badly
(tried several installations/deinstallations with it)

PHP:

---


SendMessage ${HWND_BROADCAST} ${WM_WININICHANGE} 0 "STR:Environment" /TIMEOUT=5000

If Explorer itself crashes, you probably have some rouge shell extension.

no - my system works fine. and the crash happend when opening START - Programs - <subfolder>, not anywhere else.
It exactly happend when i set timout=5000 and right after the (de-)installation (both concerned).
i can do vice versa many times without reboot...
BTW the system timeout here is set to 5000 instead windows default 20000 (all values in milli seconds).

it was this line which crashes my explorer (explorer + task bar/desktop).
It was added to the script which works well.

Fine, then it's not a rouge shell extension.

False positive. Anyway, the SendMessage solution is simpler.
