Hex-Ed is a small program that started its life some decades ago, as a BASIC program compiled in BASCOM under CP/M.
Hex-Ed was originally written to modify programs wrote in assembler. At that time processors were simpler and anyone could assemble and disassemble code reading the bytes.
The original program was rewritten in C for DOS later, and then again in Visual C for Windows. The final result is a 32-bit Hex editor.

i.Hex is a small and free graphical Hex Editor for Windows. I got ticked off at all the lame shareware hex editors out there and just buckled down and wrote my own.
i.Hex is a software that allows you edit and view HTML files.
Main features:
- Doesnt load all the file at once. Just a pane of 64K is loaded at any given time, thus it can edit/view very large files almost instantly.
- Recent file menu.
- Doesnt use the registry.
Usage
Open a file using the File->Open menu, the toolbar button or drop a file onto the window. If nothing happens, the file is locked by another application.
The offset is the number of bytes into the file the cursor is. You can seek to a particular offset by typing in the new value and hitting enter.
The hex option changes the format of the offsets both the cursor and the labels down the left hand side. When switched on the format is hex, and you enter an offset in hex, otherwise enter the offset in decimal.
The little endian option changes the byte order of the information at the cursor (display on the right most part of the toolbar). Little endian is the x86 processor format, big endian is Apple/Motrola order.
Signed changes the info format to signed values.
Once you have edited the document you can save your changes if you need to. If you move the cursor far enough away from the edits then you will be asked to save your changes, this is because only part of the file is in memory at any given time. This is a side effect of the implementation I used to allow any size files.
Use the Tab key to swap focus between the hex and ascii pane. The pane with the focus has a slightly thicker cursor line.
