[Catalyst] Catalyst on Windows: fork issues

[Kieren Diment]

Haha, here's the vbs:

Set fso = CreateObject("Scripting.FileSystemObject")
Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) &   
fso.GetParentFolderName(wscript.ScriptFullName) & "\perl
shell.bat"& Chr(34), 0
Set WshShell = Nothing

And I put a shortcut to this in ~/startup, Shortcut.exe (free  
download) seems to work.  Here's my install.bat script ;) :


@echo off
set bindir=%~dp0
set bindir=%bindir:~0,-1%
mkdir "%APPDATA%\MyPersonalHomePage"
echo ...
echo Copying application to hard drive, please be patient ....
xcopy /E /C /Y /Q  "%bindir%" "%APPDATA%\MyPersonalHomePage"
echo ...
echo Creating link in  startup folder
echo ...
mkdir "%APPDATA%\..\Start Menu\Programs\Startup"
Shortcut.exe /R:7 /A:C /T:"%APPDATA%\MyPersonalHomePage 
\startmyphp.vbs"  /F:"%AP
PDATA%\..\Start Menu\Programs\Startup\Start Personal Home Page  
Server.lnk"
"%APPDATA%\MyPersonalHomePage\startmyphp.vbs"
