Error getting map key value

Hello,
I created a map and I populated it like this:

Code:

  map.Put("2016062309343853.jpg", "c:\desktop")  

When I want to retrieve the key value, i do this

Code:

  Dim i as int
i = 0
map.GetKeyAt(i)  

but I get this error log:

Code:

  java.lang.NumberFormatException: Invalid double: "2016062309343853.jpg"
    at java.lang.StringToReal.invalidReal(StringToReal.java:63)
    at java.lang.StringToReal.parseDouble(StringToReal.java:269)
