You can use the GetInvalidFileNameChars method from the System.Io.Path. But suppose you needed to know exactly what you could not have in a file name how would you do that? Well it is easy. I generally stick with letters and numbers for my file names. Dude! You mean you cannot remember all the things you are not allowed to have in a file name? (Uh, join the club.) I know some of the things, and I know some things that I do not like in file names (such as spaces), but that is about it. Next we need to get a list of all the things you are not allowed to have in a file name. This is seen here in this demo script: Function addOne($in)īack to the GetFileName function-when you want to pass a variable by reference, you need to use the type constraint to make the variable into a reference type. Inside the function the value of the variable may change, but when the script is done, the value of the variable remains unchanged. When that happens, the value of the variable is what is important.

When we pass a variable to a function by reference, it means we will be changing the value of the variable inside the function, and then handing that value back to the code that called the function.Īnother way to call a function is to pass a variable by value. VBScript functions are talked about here. We are going to pass a variable to the function by reference. To do this we use the function keyword, and give it the name of the function. The first thing we do is create a function named GetFileName. New-item -path c:\fso -name $filename -itemtype file $invalidChars = ::GetInvalidFileNamechars() Here’s the sscript: Function GetFileName($fileName) Inside this function we use a couple of pretty cool methods to create the file name for you. The main logic of today’s script is contained in a function we have called GetFileName. The lights went off and two flame pots erupted.

It was a fine spring evening, ink-black sky, full moon, and not a cloud in the sky. So I was back in Munich, Germany, a couple of years ago, and the Stones were on stage. Can this be done?Įver since I read your e-mail message, I have had this old Rolling Stones tune stuck in my head (which is much better than having “I’ve got a brand new pair of roller skates…”), and it is causing some serious brain itch.
Hey, Scripting Guy! How can I create a file name from the date? I have this application that creates a log file, and every hour I would like to save that log file as a file whose name is generated from the current time stamp.
