ATBinHex Component

11 |
12 | 13 | ATBinHex is a control that implements the quick file (stream) viewer. 14 | Only visible part of file (or stream) is loaded into viewer, so it's suitable 15 | to show files of unlimited size. Features: 16 | 17 |
    18 |
  • Support for huge file sizes (of type Int64) 19 |
  • Support for Unicode file names 20 |
  • Support for multiple codepages: ANSI, OEM, EBCDIC, KOI8, ISO, Mac etc. 21 |
  • Many service methods implemented: copying to Clipboard, printing, search etc. 22 |
23 | 24 |

25 | There are 5 view modes available: 26 |

    27 |
  • Text: file is shown in text form 28 |
  • Binary: file is shown in binary form, with fixed line length 29 |
  • Hex: file is shown in hex dump 30 |
  • Unicode: Unicode contents of file is shown 31 |
  • Unicode/Hex: combined Hex and Unicode modes 32 |
33 | 34 |
35 |


Text mode 36 |


Binary mode 37 |


Hex mode 38 |


Unicode mode 39 |


Unicode/Hex mode 40 |

41 | 42 |

43 | There is extended version of this component available, 44 | ATViewer, 45 | which can show files in such modes as RTF, Image, Multimedia, Internet and WLX Plugins. 46 | But if you just need to show a plain file dump, ATBinHex should be enough. 47 | 48 |

49 | There is also FreePascal/Lazarus version (ported from original version), 50 | which is maintained by independent developer. 51 | This version is currently in beta stage, some features are not yet implemented. 52 | Refer to LuiPack page. 53 | 54 | 55 | 56 | -------------------------------------------------------------------------------- /help_delphi/source/License.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | License 6 | 7 | 8 | 9 | 10 |

Hints and FAQ

11 |
12 | 13 |

14 | Q1: How can I load the contents of an AnsiString or WideString? 15 | 16 |

17 | A: You should do it using OpenStream method, giving it a TMemoryStream as 18 | a parameter. Sample procedures for AnsiString and WideString are shown 19 | below. Note that you should free stream only after calling 20 | Viewer.OpenStream(nil), otherwise control will try to read deallocated 21 | memory on scrolling! 22 | 23 |

24 |

25 | 69 |
70 | 71 |

72 |

73 | 74 |

75 | Q2: I have an issue with horizontal scrollbar. Even when text becomes 76 | short enough, scrollbar doesn't disappear... 77 | 78 |

79 | A: This is done as workaround for Windows XP bug: when scrollbar is about 80 | to disappear, this may cause both scrollbars and window border to disappear. 81 | You can disable this workaround by commenting the "HSCROLLBAR_WORKAROUND" 82 | define in ATBinHexOptions.inc. 83 | 84 |

85 | The RichEdit control doesn't have this problem because it precalculates widths for all strings 86 | and sets scrollbar size to the max value. 87 | We cannot do this in ATBinHex control, so the scrollbar size is calculated dinamically. 88 | 89 |

90 |

91 | 92 | 93 |

94 | Q3: After changing a property, it is not applied. 95 | 96 |

97 | A: Many properties require that after changing them, file should 98 | be reopened (using Open/Reload methods). 99 | 100 | 101 | 102 | 103 | -------------------------------------------------------------------------------- /help_delphi/source/Usage Methods.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | Usage: Methods 6 | 7 | 8 | 9 | 10 |

function Open(const AFileName: WideString; ARedraw: Boolean = True): Boolean;
16 | Opens a file and optionally redraws control.
17 | Result is True if file was successfully opened 18 | or False if file was not found or other open error occured.
19 | Pass the empty AFileName string to close the currently open file.
20 | Note:
21 |
    22 |
  • ARedraw parameter must be set to False in the case you create ATBinHex 23 | object at run-time and then call Open('')/OpenStream(nil) in your destructor 24 | to free data. In this case the control must not be redrawn 25 | because this will cause its parent access error. 26 |
27 |
function OpenStream(AStream: TStream; ARedraw: Boolean = True): Boolean;
31 | Opens a stream and optionally redraws control.
32 | Result is True if stream was successfully opened.
33 | Pass nil to stop use the currently used stream.
34 | Notes:
35 |
    36 |
  • See note for Open.
    • 37 |
  • Stream is not freed automatically, you should free it by yourself, 38 | but only after you call OpenStream(nil).
    • 39 |
  • In Delphi 5 TStream.Size is declared as Longint, 40 | so if you are going to open streams larger than 2 Gb, you should 41 | use newer Delphi versions which declare TStream.Size as Int64.
    • 42 |
43 |
procedure Reload;
47 | Reloads current file or stream. 48 |
function FindFirst(const AText: WideString; AOptions: TATStreamSearchOptions): Boolean;
52 | Starts text search.
53 | AText: text to search (Note: Unicode string must be in the Little-Endian format).
54 | AOptions: search options that are set of flags:
55 |
    56 |
  • asoWholeWords: Search for whole words only
    • 57 |
  • asoCaseSens: Case-sensitive search
    • 58 |
  • asoBackward: Backward search (Note: not supported for RegEx search)
    • 59 |
  • asoRegEx: RegEx (regular expressions) search
    • 60 |
  • asoRegExMLine: Multiline regex search (used with asoRegEx)
    • 61 |
  • asoFromPage: Starts search from the current page, otherwise in entire file
    • 62 |
  • asoShowAll: Highlights all occurances of search string
    • 63 |
64 | Result is True if text was found.
65 | Match position and length are saved in SearchResultStart and SearchResultLength properties. 66 | You should manually highlight found match using SetSelection method.
67 | Notes:
68 |
    69 |
  • RegEx search (asoRegEx option) is available only when RegEx library is compiled in. 70 | See ATStreamSearchOptions.inc file.
    • 71 |
  • Unicode-named files can be handled during search only when Tnt Unicode 72 | Controls are compiled in. See ATStreamSearchOptions.inc file.
    • 73 |
  • When non-RegEx search is performed, two 74 | different search functions are used: one for 1-byte Text/Binary/Hex 75 | modes and other for Unicode modes; they give different search results.
    • 76 |
77 |
function FindNext(AFindPrevious: Boolean = False): Boolean;
81 | Continues text search.
82 | AFindPrevious: continue search in reverse direction (Note: not supported for RegEx search).
83 | Result is the same as for FindFirst method.
84 | Note:
85 |
    86 |
  • After you change view mode or reload a file, you cannot continue search immediately, 87 | you must first call FindFirst.
    • 88 |
89 |
procedure CopyToClipboard(AsHex: Boolean = False);
93 | Copies current selection (AnsiString or WideString depending on current view mode) 94 | to Clipboard.
95 | AsHex may be True in Text/Binary/Hex modes, in this case 96 | the hex-encoded string (bytes in the hex form separated by spaces) will be 97 | copied.
98 | Notes:
99 |
    100 |
  • This procedure may fail and show an error message if selection is too big to fit in memory.
    • 101 |
  • To prevent visual "hanging" during copying of too large block, 102 | data size is internally limited by MaxClipboardDataSizeMb value.
    • 103 |
104 |
procedure SetSelection(const AStart, ALength: Int64; AScroll: Boolean; AFireEvent: Boolean = True; ARedraw: Boolean = True);
108 | Sets selection and optionally scrolls control to selection start.
109 | AStart: selection start (0-based),
110 | ALength: selection length,
111 | AScroll: scroll control to selection start afterwards,
112 | AFireEvent: fire the OnSelectionChange event afterwards,
113 | ARedraw: redraw control afterwards.
114 | Note:
115 |
    116 |
  • If AScroll = True, control will be scrolled using the code: 117 | 
      Scroll(AStart, TextSearchIndentVert, TextSearchIndentHorz);
    118 |
119 |
procedure Scroll(const APos: Int64; AIndentVert, AIndentHorz: integer; ARedraw: Boolean = True);
123 | Scrolls control to specified position.
124 | Control will be scrolled vertically so that position APos (0-based) is visible 125 | by AIndentVert lines lower than top border; 126 | if after that the position is still out of screen, control will be 127 | scrolled horizontally so that position is visible by AIndentHorz chars righter than left border.
128 | ARedraw: allow to redraw control afterwards. 129 |
133 | procedure SelectAll;
134 | procedure SelectNone;
135 | Selects all text.
136 | Deselects text. 137 |
140 | 141 | procedure Print( 142 | APrintRange: TPrintRange; 143 | AFromPage: Integer = 1; 144 | AToPage: Integer = MaxInt; 145 | ACopies: Integer = 1; 146 | const ACaption: string = ''); 147 |
148 | Shows "Print preview" dialog and allows user to print text.
149 | APrintRange: print range (type declared in Dialogs.pas): 150 |
    151 |
  • prAllPages: prints all text. 152 |
  • prSelection: prints selection only. 153 |
  • prPageNums: prints pages from AFromPage to AToPage. 154 |
155 | ACopies: number of print copies,
156 | ACaption: caption of print job.
157 | Notes: 158 |
    159 |
  • This method shows "Print preview" form only when ATPrintPreview component 160 | is used by enabling the "PREVIEW" define in ATBinHexOptions.inc. 161 | Otherwise it just prints the text without questions. 162 |
  • Resulting page sizes are affected by Margin* properties 163 | and printer page sizes, not by visible control size. 164 |
165 |
procedure PrintPreview;
169 | Shows "Print preview" dialog for current selection.
170 | When text is selected (SelLength <> 0), this method calls 171 | Print(prSelection), otherwise it calls Print(prAllPages). 172 | Note: 173 |
    174 |
  • This method works only when ATPrintPreview component is used 175 | by enabling the "PREVIEW" define in ATBinHexOptions.inc. 176 | Otherwise it does nothing. 177 |
178 |
function IncreaseFontSize(AIncrement: Boolean): Boolean;
182 | Increases (AIncrement = True) or decreases current font size.
183 | Result is True if font size was changed or False if minimal 184 | or maximal size value is already set.
185 | Note:
186 |
    187 |
  • For raster fonts (the default OEM font is raster) 188 | this size change is not simple increment by one.
    • 189 |
190 |
procedure TextEncodingsMenu(AX, AY: Integer);
194 | Shows menu of all available encodings for the current mode.
195 | Menu is shown at point (AX, AY).
196 | Note:
197 |
    198 |
  • In Unicode modes this method displays the special Unicode menu, 199 | which contains only "UTF-16 LE" and "UTF-16 BE" items. 200 |

      46 |
    • ANSI, OEM, EBCDIC, KOI8, ISO, Mac encodings are always available. 47 |
    • EBCDIC, KOI8, ISO, Mac encodings are used via MultiByteToWideChar API, if possible. 48 | But if they are not installed on OS (for example, on Win9x), 49 | then the hardcoded codepages are used. 50 |
    • All other encodings are used via MultiByteToWideChar API, 51 | they are available only when installed on OS. 52 |
    53 |
54 |
TextEncodingName (public, read-only)Name of current text encoding.
59 | Note:
60 |
    61 |

286 | These values are for all view modes of ATBinHex control: Text, Binary, Hex, Unicode. 287 | They set internal values that define the maximal length of a single string in a file. 288 | Values are 300 by default. 289 | For example, you may set MaxLengths[vbmodeText] to 1000 if user needs to work 290 | with strings of length 1000 in Text mode.
Notes:
291 |
    292 |
  • Larger values increase size of memory buffer for a file, and slow down file reading. 293 |
  • Values are applied after file reopening, e.g. after calling Open/OpenStream/Reload methods 294 | and after changing Mode property. 295 |
296 |
MaxClipboardDataSizeMb (public)Maximal data size (in Mb) for copying to Clipboard.
300 | Default value is 16 (Mb), which prevents visual "hanging" when too large block 301 | is selected accidentally before copying. 302 |

324 | Note:
325 |
    326 |
  • You should call SelText/SelTextW inside try...except block, 327 | because when selection is too big, exception is generated. 328 |
329 |
334 | 335 | PosPercent
336 | PosOffset
337 | PosLine 338 | (public) 339 | 		Current scroll position: 342 |

Thread-safety note

11 |
12 | 13 | The current component version is not thread safe. But if you need to use it in a multi-thread 14 | application, the following hint should help to use it right. For example, you need 15 | to call Open method from several threads. Don't do this, instead do it in message way: 16 | all threads should send a message (it may be some Windows message not used in your application, 17 | e.g. EM_DISPLAYBAND) to main thread, informing it that a filename should be opened. 18 | Pointer to a filename can be passed as message parameter. 19 | So the main message handler calls Open. 20 | 21 |

22 | Note: this may be a risk of receiving messages from several threads at almost the same time, 23 | so additional boolean "Busy flag" should be set on message-handler start and reset on exit. 24 | 25 | 26 | 27 | -------------------------------------------------------------------------------- /help_delphi/source/c.bat: -------------------------------------------------------------------------------- 1 | @echo off 2 | cls 3 | "C:\Program Files\HTML Help Workshop\hhc.exe" ATBinHex.hhp 4 | -------------------------------------------------------------------------------- /history.txt: -------------------------------------------------------------------------------- 1 | 2024.07.01 2 | + add: props MarkerStart, MarkerLength, MarkerLineWidth, TextColorMarker 3 | 4 | 2023.12.01 5 | * change: disabled selection with UTF8 encoding, to hide wrong selection with UTF8 6 | * change: support proportional fonts, but now rendering is slower due to call of TCanvas.TextWidth for each char 7 | + add: DoubleBuffered property, it now allows correct rendering on macOS Retina if set to False 8 | - fix: TextWrap is now working 9 | 10 | 2019.09.19 11 | * change: require package EncConv (in github.com/alexey-t) instead of LConvEncoding 12 | 13 | 2018.04.10 14 | - fix: double-click worked wrong (must react in MouseUp, not in DblClick) 15 | - fix: wrong find of whole words 16 | 17 | 2018.04.07 18 | + add: update resource pic for "middle mouse click scroll" for hi-dpi 19 | + add: rewritten other resource files 20 | 21 | 2017.12.18 22 | + add: use unicode middle-dot U+00B7 for special chars 23 | 24 | 2017.12.15 25 | + big rework.
