Hi pho_nox,
directly you can not connect it, since the textbox output is a String, but you can use function Convert string to path form Functions palette (Programming->String->String/Array/Path Conversion).
I have tried it with Prompt User for Input Express vi. You have to give in text entry box the whole path including file name + file extension (.txt), connect the output string of express vi with function convert string to path and than give directly it to the path input of open/create/replace file LabVIEW function.
