XE - Simple file viewer & editor
#1
XE is a simple Binary File Editor (also called a HEX editor) that lets you view and edit raw data bytes of a file.  With XE you can peek inside EXE/DLL files and see what information they may contain.  XE also has the capacity to change bytes by either typing in ASCII characters or entering the HEX value for each byte.  XE was first coded in Qbasic - now in QB64.   Since the very nature of XE is to alter file data you should always use EXTREME caution when editing any file - AND ALWAYS MAKE A BACKUP FIRST!

This code will work in Windows & Linux.

' ABOUT:
' ~~~~~
'
' XE is a simple Binary File Editor (also called a HEX editor) that lets
' you view and edit raw data bytes of a file.  With XE you can peek inside
' EXE/DLL files and see what information they may contain.  XE also has the
' capacity to change bytes by either typing in ASCII characters or entering
' the HEX value for each byte.  XE was first coded in Qbasic - now in QB64.
'
' Since the very nature of XE is to alter file data you should always use
' EXTREME caution when editing any file - AND ALWAYS MAKE A BACKUP FIRST!
'
'==========================================================================
'
' HOW TO USE:
' ~~~~~~~~~~
'
' XE accepts command line arguments.  You can drag/drop a file onto XE.
' If you don't specify a filename on startup, XE will ask you for one.
'
' There are TWO ways to View & Edit files - in HEX (default) or ASCII mode.
'
' Files are first opened in HEX mode displaying 2 windows of data.  The
' right window shows the charaters while the larger left window shows HEX
' values for them. HEX mode is best for patching and is the only way to
' edit the HEX values of bytes.
'
'
' Pressing ENTER switches to ASCII (non-HEX) mode, showing a larger page
' of raw data bytes - the ASCII chracter data only.  This mode is best for
' skimming through files faster.  ENTER toggles view modes back and forth.
'
' While viewing a file you can browse through the file using the ARROWS,
' PAGEUP/DOWN, HOME and the END keys.
'
' The currently opened filename is shown with full path in the title bar.
' and just filename is displayed in the FILE: area just below title bar.
'
' While viewing a file, press E to enter into EDIT mode and begin editing
' bytes at the current position. If you're in HEX mode (2 windows), you can
' edit bytes either by typing characters on the right side or entering HEX
' values on the left window.  Press TAB to switch windows to edit in.
' Press ESC to save or disgard changes and to exit editing mode.
'
' Press M for a complete MENU listing all of the Key COMMANDS.
'
'==========================================================================
'
' COMMAND:
' ~~~~~~~~
'
'         E  =  Enters EDIT MODE. Only the displayed bytes can be edited.
'
'       TAB  =  Switchs panes (the cursor) while editing in HEX mode.
'
'         S  =  Searches file for a string starting at the current byte.
'               A Match-Case option is available.  A high beep alerts you
'               when match is found. A Low beep sounds when EOF reached.
'
'         N  =  Finds NEXT Match after a do a string search.
'
'         F  =  Toggles FILTERING of all non-standard-text characters.
'               A flashing "F" is at the top-left corner when FILTER ON.
'
'         G  =  GOTO a certain byte position (number) in the file.
'
'         L  =  GOTO a specified location (Hex value) of the file.
'
'     ENTER  =  Toggles HEX and ASCII view modes.  The ASCII mode lets
'               you browse more data per page.  You can EDIT in both
'               modes but can only enter in HEX vaules in HEX mode.
'
'       ESC  =  EXITS out of editing mode, and also EXITS the program.
'
' ALT+ENTER  =  Toggle FULLSCREEN/WINDOWED mode of the XE program.

Hi, nice done.
Can yoy tell me more about the reason you use the FONT SUB?
=> FONT (INT(_DESKTOPHEIGHT / 25) * .88)
Just because it expands SCREEN 0 nicely ???

Yes, it makes a system like font that can be resized, and I call it that way so it make an expanded SCREEN 0 based on the users desktop size. This way makes a really big SCREEN 0.

Nice.
But not the best font or idea with WIDTH 80,50 even if you change the function to FONT (INT(_DESKTOPHEIGHT / 50) * .88)

I have updated this program to v1.13.  Now uses _OPENFILEDIALOG to select files, and did some other tweaks.

@BDS170: Thank you for your feedback.  I will test this in other settings like you mentioned (80/50) and see about improving the FONT usage.  Thanks for testing this program!
