How to open a directory with a windows system variable in the path?

[BACL]

Hi m8s,

Does anyone know in AMS how to open a directory with a windows system variable in the path?

Like this:

%HOMEPATH%\AppData\

By default the %HOMEPATH% points to C:\Users\[user name]\
in Win7.

Many thanks!

%HOMEPATH% is an environment variable, and you can retrieve the contents of environment variables with os.getenv(), like in this sample:

local sPath = os.getenv("HOMEDRIVE") .. os.getenv("HOMEPATH") .. "\\AppData";
Dialog.Message("Info", sPath);

thanks urich

as we know
we can open folders with the file.open command
this code will work

File.Open("c:\\", "", SW_SHOWNORMAL); 

why this one not work??

local sPath = os.getenv("HOMEDRIVE") .. os.getenv("HOMEPATH") .. "\\AppData";
File.Open(sPath, "", SW_SHOWNORMAL);

File.Open() is for "opening" files or documents, not folders. If you want to show the contents of a folder, you should use File.ExploreFolder() instead, right?

yes urich

but also

local sPath = os.getenv("HOMEDRIVE") .. os.getenv("HOMEPATH") .. "\\AppData";
File.ExploreFolder(sPath) 

do not show the content of the folder sPath

remark
i think that the command (file.open) opens the folder in the shell command "open"
and the command (File.ExploreFolder) opens the folders in the shell command "explore"

thanks

also

sPath = Shell.GetFolder(SHF_APPLICATIONDATA);
File.ExploreFolder(sPath) 

works for me
my os is win xp

On Windows XP you most probably won't find a sub folder named "AppData" in the user profile. That was not what was asked in the original question - the question was how to use an environment variable.
