Editing a Binary File

Question

Hello: I have an older version of Visual Studio (2010). Are there examples posted on this forum of using Visual Basic to Open a Binary file, search for a character string (in either hex or ASCII), update the string (with the ability to add characters - i.e. the search finds a 2 character string, and replace it with a 5 character string, making the file longer), and save the file with a new name?

Thanks,

Hi RichLocus,

You could refer to this document: How to: Read From Binary Files in Visual Basic, and related interfaces here: FileStream Class and FileStream.Read Method.
