How do I make a direct call to the operating system directory without necessarily having to say "c:\windows", is there not a command like $%OSRoot%$?

I'm pretty sure there are a number of such commands such as making a direct call to the root without having to type "c:\", is there perhaps a list where I could find such statements?

A function like this will do the job:

function GetWindowsPath: String;
begin
 SetLength(Result, MAX_PATH);
 GetWindowsDirectory(PChar(Result), MAX_PATH);
end;

What are you trying to do?

I'm storing a number of files within the windows temporary folder during the operation of my program (an email browser). I simply want to empty the temporary folder when I exit the program.

You'd better get a path to the windows Temp dir, and create a subdir, just for yourself, that you empty & delete on exit. This way you won't get conflicts with other programs that have open files in the temp dir.

Windows temp is not nessecerily in %WINDOWS%\TEMP, so ...

And the way to get the Temp directory is to use something like this:

function GetTemporaryPath: String;
begin
 SetLength(Result, MAX_PATH);
 GetTempPath(MAX_PATH, pchar(result) );
end;

Note the annoying inconsistency in the order of parameters between GetTempPath and GetWindowsDirectory.

I'm having trouble with getting the directory. When I check the contents of the result of the Function, the first part does display the directory but then i get a long line of gibberish i.e. ##@#@#$$ etc. I'm guessing that these characters must be place holders for the remaning characters as the path has not used the 255 character size specified by MAX_PATH.

Any ideas?

You prob. have to scan for the first #0 in the output to find the actual length of the path.
