For loop of death

This is a way to somewhat defend yourself when a process keeps on respawning itself and won't go away. This happens quite a bit when XP gets infiltrated by malware.

for /l %a in (1,1,1000000) do taskkill /im malware.exe /f

Universal scripted uninstall (XP)

Given the displayname value, this vbscript will go and find it in the registry and uninstall the corresponding program.

This is where it searches:

hklm\software\microsoft\windows\currentversion\uninstall

' arg 1 - displayname


if (wscript.arguments.count > 0 ) then

 set shell = wscript.createobject("wscript.shell")
 strcmd = "reg query hklm\software\microsoft\windows\currentversion\uninstall /s"

 set oexec = shell.exec(strcmd)

 temp = 0
 parent = ""

 do while not oexec.stdout.atendofstream

  strline = oexec.stdout.readline


  if len(strline) > 0 then
   a=split(strline,vbtab)
   if mid(trim(a(0)),1,4) = "HKEY" then
    b = split(trim(a(0)),"\")
    parent = b(ubound(b))
    temp = 1
   end if   
   alen = ubound(a) + 1
   if alen >= 3 then
    if trim(a(0)) = "DisplayName" and trim(a(2)) = wscript.arguments(0) and temp = 1 then
     wscript.echo "msiexec /x " & parent & " /qn"
     temp = 0
     shell.exec("msiexec /x " & parent & " /qn")
     exit do
    end if
        
   end if
  end if
 loop




end if

Solution to generating markers along a route at a regular interval

I found this neat javascript extension for the google map api. Here is the link:

http://econym.org.uk/gmap/epoly.htm

You specify the distance and give it a polyline and it returns an array of points along the route.

map.setCenter(new GLatLng(42.351505,-71.094455), 15);
    var directionsPanel = document.getElementById("directions_div");
    var directions = new GDirections(map, directionsPanel);
    var address = "from: trenton, nj to: philadelphia, pa";

    directions.load(new_address);
  if (directions == null){
    alert("Error: directions object is null");
    return;
   }
   
   var pl = directions.getPolyline();
   
   if (pl == null){
    alert("Error: polyline object is null");
    return;
   }
   
   var points = pl.GetPointsAtDistance(1609.344);

   if (points == null){
    return;     
   }
   
   for (var i=0; i
    map.addOverlay(new GMarker(points[i]));
   }
