create a new text file

[rr1024]

Open/Create/Replace only seems to allow writing to an existing file, every time I try to type a new name in it's throws an error saying the file dosn't exist. See attached

[James.M]

There's an "operation" input. Default is "Open", which doesn't create a new file. Create a constant to set the input to Open or Create.

Also note that the Open/Create/Replace will not create the directory structure.  You should use Create Folder (in the File IO->Advanced palette) to create the folder you want to put the file in if the folder does not exist.

Sounds like a great solution except I can't seem to add that text to the constant see attached. Obviously doing something wrong

Right-click on the input and select Create->Constant

Uhhhh... never seen that before. It looks like you're just trying to put down some kind of generic selector box. What happens when you right click the input and select Create > Constant.

[SigRob]

That box is actually an Enumeration, a specific type of constant assoicated with that file open VI.  You need to right-click on the connector and say Create->constant and that will give you the correct one.
