I have been looking on the internet for how to do a save as on my form, but can't seem to figure it out. All I know is you can do something with the saveFileDialog, but I don't even see it pop up.
I want to incorporate 8 Different SaveAs in my form, and each one will save a different text. for example the user clicks Save Blah then a SaveAs dialog box opens up to save the text to the computer and once they save it into a spot they can open the file and it says"blah blah".
