Hi, I wrote a simple program to test the "out-of-the-box"
functionalities of the CMAB (Configuration Management Application
Block).
After having added 2 values to an hashtable, and having written that
hashtable (using the XmlHashtableSec tionHandler) to an XML file (using
the XmlFileStorage) I try to read back the hashtable with those
values. I am adding a "string" value (with a string key) and a
"double" value (also with a string key) to the hashtable.
The problem is that even though it all seems fine in the xmlStorage
file, when I read back the hashtable from the Configurationma nager,
and try to get both the string and double value back, it seems that
they are both restored as strings, I mean, the hashtable (restored
from the xmlStorage file) has the double value converted as a string,
although it was stored as a double. So, an InvalidCastExce ption is
thrown when I try to get the double value.
Anyone knows what the problem might be?
Thanks in advance,
Ricardo Pereira

Hashtable table;

string s = (string)table["ip"];
double x = (double)table["numberOfX"];
