About reading files. [Solved]

Does anyone know how to make it when I double click on a certain file type e.g. "File.cat" then it opens up a executable I made in VB and puts the text from "File.cat" in a textbox.

I know how to make it when you double click on the file then it opens the executable put I don't know how to make it put the text from the file into a Textbox in the executable. Can someone please help me?

When you double-click on the file, the file name will be sent to your program on a command line - which you can read this from the Command function, eg:

Code:

---

Msgbox "File to open: " & Command

---

As to actually loading the file, see this article from our Classic VB FAQs.

Thanks you very much!
