Re^2: Calling an executable and entering login credentials
in thread Calling an executable and entering login credentials
Batch files don't ask for passwords. Programs invoked by the batch files do that. Look at the batch file, find out which program asks for a password, read its documentation and find a way to pass the password on the command line. Or look at tools like AutoIt that are written to interact with GUIs.
Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
