|

|
---|
| 11 | * Revision History:
|
---|
| 12 | * Programmer Date Description
|
---|
| 13 | * sraj 05/18/2004 Fixed Delphi 5 compilation issues.
|
---|
| 14 | * sraj 07/25/2003 Supported TTreeView items collection in properties.
|
---|
| 15 | * sraj 07/25/2003 Supported TStringGrid object data.
|
---|
| 16 | * sraj 24/04/2003 RATLC00447073: Included FindControl1() to lookup delphi object
|
---|
| 17 | * given a window handle effectively.
|
---|
| 18 | * sraj 10/03/2002 RATLC00436896, RATLC00052492 : Included BeautifyApplicationWindow
|
---|
| 19 | * sraj 06/23/2003 RATLC00449186 : Exception trace enabled using a Registry key.
|
---|
| 20 | * sraj 10/03/2002 RATLC00436896, RATLC00052492 : Included BeautifyApplicationWindow
|
---|
| 21 | * to make application object available as a window property.
|
---|
| 22 | * Removed the call RegisterAutomationServer() from unit Initialization.
|
---|
| 23 | * PBeaulieu 01/08/2002 Changed TPublishedAutoDispatch.NewDispatch to set the found
|
---|
| 24 | * flag if found in first case to bypass the second search method.
|
---|
| 25 | * PBeaulieu 08/20/2001 Changed TIObjectDispatch.GetProperty inorder to make
|
---|
| 26 | * sure that Unassigned Variant or incorrect Variant type
|
---|
| 27 | * would not be used in retrieving a property. Changed
|
---|
| 28 | * TPublishedAutoDispatch.NewDispatch to search manually the
|
---|
| 29 | * inheritance hierarchy if InheritsFrom fails. This allows
|
---|
| 30 | * for objects that the InheritsFrom function fails on
|
---|
| 31 | * seemingly because it cannot access the information with
|
---|
| 32 | * the functions it is using. This seemed to happen with
|
---|
| 33 | * MDI app where the MDI children were created from another
|
---|
| 34 | * dll that encapsulated the form in another object.
|
---|
| 35 | * PBeaulieu 06/26/01 Merged in Pete Ness's changes to fix some warnings and
|
---|
| 36 | * to add some logging for exceptions. Also, added the function
|
---|
| 37 | * TIObjectDispatch.ParentClassName.
|
---|
| 38 | * PMNess 05/16/01 Changed the "Classname" calls in TPublishedAutoDispatch
|
---|
| 39 | * to FObject.Classname - as Classname was always
|
---|
| 40 | * returning TPublishedAutoDispatch instead of
|
---|
| 41 | * the actual invoked class.
|
---|
| 42 | * PMNess 05/15/01 Updated and removed hints/warnings under D5
|
---|
| 43 | * Added try/excepts around all automated calls
|
---|
| 44 | * to trap exceptions that may happen and log to
|
---|
| 45 | * file.
|
---|
| 46 | * KPATEL 05/25/00 Replaced the function 'VarAsType' with
|
---|
| 47 | * 'VarToStr' as Delphi 5 takes only string as
|
---|
| 48 | * the third parameter in SetStrProp function.
|
---|
| 49 | * SJPak 03/31/98 Modified TIObjectDispatch.GetEnumList to
|
---|
| 50 | * return empty variant when the total length of
|
---|
| 51 | * the strings for enumerated choices exceed
|
---|
| 52 | * 2047. This is to keep Robot from crashing
|
---|
| 53 | * Robot cannot handle more 2048 characters total.
|
---|
| 54 | * SJPak 04/02/97 Modified TPublishedAutoDispatch.Invoke to
|
---|
| 55 | * support TColor type properties.
|
---|
| 56 | * SJPak 08/04/96 Added additional interface TIStringGridDispatch
|
---|
| 57 | * to support Cols and Rows properties of TStringGrid.
|
---|
| 58 | * SJPak 03/06/97 Modified TICollectionDispatch.GetPropNames
|
---|
| 59 | * and TICollectionDispatch.GetProperty to support
|
---|
| 60 | * Items property.
|
---|
| 61 | * SJPak 11/21/96 Replacing calls to OLECheck which
|
---|
| 62 | * will raise an exception when return value
|
---|
| 63 | * is less than 0. Raising an exception
|
---|
| 64 | * will cause a messagebox to pop up when ran
|
---|
| 65 | * from Delphi IDE.
|
---|
| 66 | * SJPak 11/15/96 Fixed a memory leak in
|
---|
| 67 | * TIObjectDispatch.SetProperty
|
---|
| 68 | * SJPak 11/11/96 Modified TIStringsDispatch.GetProperty
|
---|
| 69 | * to check for empty "Strings" property.
|
---|
| 70 | * SJPak 11/07/96 Removed calls to OleError to prevent
|
---|
| 71 | * error messages being displayed during
|
---|
| 72 | * Rec/Plaback session through IDE.
|
---|
| 73 | * SJPak 10/07/96 Modified TIStringsDispatch to support
|
---|
| 74 | * Strings property of TStrings object.
|
---|
| 75 | * SJPak 09/19/96 Changed CLSID of the server.
|
---|
| 76 | * SJPak 08/04/96 Added additional interface TIOleControlDispatch
|
---|
| 77 | * to support OCXs.
|
---|
| 78 | * SJPak 08/01/96 Modified TPublishedAutoDispatch.Invoke
|
---|
| 79 | * to return tkSet type properties as
|
---|
| 80 | * a safe array of Variants containing
|
---|
| 81 | * names of all possible items in the set
|
---|
| 82 | * and booleans representing whether the items
|
---|
| 83 | * are in the particular set.
|
---|
| 84 | * SJPak 07/31/96 Fixed Borland's bug in
|
---|
| 85 | * TPublishedAutoDispatch.Invoke function's
|
---|
| 86 | * handling of min and max values of
|
---|
| 87 | * tkSet properties.
|
---|
| 88 | * SJPak 07/18/96 Changed Unit name to SQASrvr
|
---|
| 89 | * SJPak 07/18/96 Added addtional interface TIStringsDispatch
|
---|
| 90 | * to support TStrings class.
|
---|
| 91 | * SJPak 07/18/96 Added GetPropNames and GetProeprty to
|
---|
| 92 | * TICollectionDispatch.
|
---|
| 93 | * SJPak 07/18/96 Added GetPropNames method to TIObjectDispatch
|
---|
| 94 | * interface.
|
---|
| 95 | * SJPak 07/08/96 Added SetProperty method to TIObjectDispatch
|
---|
| 96 | * interface.
|
---|
| 97 | * SJPak 07/08/96 Additional interface define for
|
---|
| 98 | * DatSet Objects.
|
---|
| 99 | * SJPak 07/01/96 Fixed a bug in TPublishedAutoDispatch.Invoke
|
---|
| 100 | * SJPak 07/01/96 Additional interface defined for
|
---|
| 101 | * collections.
|
---|
| 102 | * SJPak 07/01/96 Original From Delphi.
