NUL String

[jyang72211]

I have a string combo box.  Is it possible to have the ascii "NUL" (00 in hex) as a selection in the combo box?  I need the combo box to select a list of strings, but I also need the NUL option, since I need the hex number x00 sometimes. 

string => hex equivalent

NA => x00

string1 =>hex equivalent

string 2 =>hex equivalent

string 3 =>hex equivalent

I guess the empty string constant is equal to a NUL string.

Use the normall string NULL, in the event (or after the control) you check if the value equals to NULL, and then you output x00.

This can be easily done in a sub-vi.

No it's not, an empty string has lenght 0, a string with the value NULL has a length of 1.

However in C, a NULL string is an empty string since they are NULL-terminated.
