Char to hex or hex to char conversion in TestStand

[TonyJ]

How can I use the expressions browser in TestStand to make a character to hex or hex to character conversion?  I'm using TestStand 3.0

I'm not completely sure what you are looking for but:

To convert a character to a hex string representing its ascii value:

Str(Asc("a"), "%x")

---> "61"

To convert a hex string representing an ascii value to a character:

Chr(Val("0x" + "61"))     // note that the 0x prefix is needed if the hex string doesn't already have it

---> "a"

Hi,

is it possible to convert long char to  hex  in TestStand? For example how to convert string "System" to hex. Expression Asc() allow only converts first char in string.

Thanks for help

What exactly are you trying to do? TestStand does not store strings as unicode, it use multi-byte encoding instead. Perhaps there is a better way to accomplish what you are trying to do.

If you are using TestStand 2010, you can use the .NET adapter to use the System.String .NET API directly with TestStand strings. To do so select mscorlib from the GAC assembly list and select System.String as the class. If you select <Use Existing Object> as the first call, you can specify a TestStand string variable for the object.

Hope this helps,
