KHexEditor
Once, I just needed an integrated hexadecimal editor for one project. As I didn't find any suitable component either with Google, I decided to write my own component. This should be very easy at the beginning but grew in quite a huge project later. This component should be well tuned already because I spent much time writing it.
| KHexEditor features |
|---|
| Written as TCustomControl descendant |
| Enhanced editing capabilities for binary code |
| Many rendering styles |
| (Virtually) unlimited Undo/Redo |
| Keycode mapping |
| Fast functions for searching and replacing a binary code snippet |
| Printing and previewing of printed page |
| OS themes supported |
| Hexadecimal editor demo (quite simple) |
Necessary packages
From version 1.4 none. Up to version 1.3 JEDI Code Library (JCL) - Version 1.100+ - download here.
Compiled executable demo
Download the executable demo directly without compiling in Delphi - it is absolutely virus and spyware free: HexEditorDemo.zip

Missing 2 functions:
1. Limit editing block size - edit only block with specific size.
2. Custom from and to char mapping when displaying and entering characters.

Hi!
After repeatedly adding small chunks of data (1k..4k) for a while to the editor i suddenly get the error message
Runerror (203)
obviously an out of memory as this happens in the method TKCustomHexEditor.InsertString, to be more precise at the line
ReallocMem(FBuffer, FSize);
FSize is of the order of a few MB, any ideas how to solve this bug? By the way: it is rather odd how the display of the Editor changes when adding additional data, it is not possible to read or change any data...

Also, please add event, which triggered when cursor changes position. OnKeyUp and OnMouseUp doesn't work well when I press and holf on key/mouse button.

In Delphi XE when I enter into hex editor "1450323F593F432750" and try to find hexadecimal sequence "50" or char "P", method ExecuteCommand(ecSearch, @SearchData) can find only first occerence, but can't find second. This bug presents in sample application ..\demos\khexeditor too.

1. Method SetCharMapping does nothing: code
SetLength(MyCharMapping, 256);
for c := Low(c) to High(c)
do if c<#20
then MyCharMapping[Ord(c)]:='.'
else MyCharMapping[Ord(c)]:=c;
KHexEditor1.SetCharMapping(MyCharMapping);
has no effect.
2. KHexEditor 1.5 doesn't support input of russian chars (and, probably, any other chars with codes >127) in TKCustomHexEditor.KeyPress.
I use this fix: insted of
eaText: I := Ord(Key);
I wrote
{$IFDEF UNICODE}
eaText: begin
I:=0;
WideCharToMultiByte(DefaultSystemCodePage, 0, @Key, 1, @I, 1, nil, nil);
end;
{$ELSE}
eaText: I := Ord(Key);
{$ENDIF}
3. Please add methods "Copy", "Paste", "Undo" etc. Using "ExecuteCommand(...)" is more complicated and needs "uses KEditCommon".
4. In sample "HexEditor": when I remove suffix "0x" from component property, save project, close and open again, suffix "0x" appears again.
5. Is it possible to change separators' width programmatically? And how can I place any data into editor not via Clear/Append?

1. Corrected for next patch.
2. Patch applied.
3. Will be added when I have time.
4. Doesn't happen in my compilation. Did you find the reason?
5. No. Use Data property.

In Delphi XE when AddressPrefix='', Delphi doesn't save this value into .dfm file. When I open project again, AddressPrefix has default value '0x', not ''.

Hi!
How can I put a limit on the size of the input data?
How to programmatically enable overwrite of characters?
inserted: 2010-12-23 22:59:01

You always can type new characters and increase the buffer, there is no limit for that. You can enable overwrite mode by calling KHexEditor1.ExecuteCommand(ecOverwriteMode);

How can i add data from a simple array to the hex editor? There are only methods to load from stream or file...

Use Data or Lines property.

Could you elaborate on that? It is not obvious to me how to append single bytes or whole arrays to the Data record...

Please download latest version again. I added the Append methods to append data (Ansistring or TDataSize record) to THexEditor buffer.

Is it possible to get around the memory size, there are times I need to open 2gb files or larger?

No. You have to split it to smaller segments manually. Or we all have to wait until the 64 bit compiler comes... I don't want to segment the buffer.
