{CHANGE LOG:
V1.08: (18-10-2013 DD/MM/YYY)
***************************
** By user MARCELVK from **
** forum.openoffice.org **
***************************
-SetTextCell in OpenOffice/LibreOfice case use .string not setFormula().
-Added properties LastCol and LastRow to get the bounds of used cells.
V1.07: (15-05-2013 DD/MM/YYYY)
-From V1.03, trying to open Excel without Excel installed doesn't try to open
OO instead, just raise an error. Fixed in create().
V1.06: (08-04-2013 DD/MM/YYYY)
*******************
** Joseph Gordon **
*******************
-New function Orientation(row, Col, Angle) to rotate the text in a cell.
-Auto adjust a column's width using AutoFit(col)
V1.05: (22-02-2013 DDMMYYYY)
-Restored "$INCLUDE Compilers.inc" from V1.03 so code is suitable for other
versions of delphi (Philipe did this works, I just deleted this line ;-).
-Restored 3 commented lines with params. for a code formatter Philipe use. It
has no use for others don't using formatters, but it won't harm us!
V1.04:
-New function StillConnectedToApp() to check if user closed app. manually.
Note: Useful for previewing doc. in OO using code like this:
//
HCalc.Visible:= true;
if HCalc.IsExcel then begin
//Preview of all sheets, one after the user closes the other...
for i:= 1 to HCalc.Document.Sheets.count do
HCalc.Document.Sheets[i].PrintOut(,,,true);
end else begin
//ooDispatcher is just a variant
ooDispatcher:= HCalc.Programa.createInstance('com.sun.star.frame.DispatchHelper');
ooDispatcher.executeDispatch(HCalc.Document.getCurrentController.getFrame, '.uno:PrintPreview', '', 0, VarArrayCreate([0, -1], varVariant));
//OO returns control just after showing, while excel waits for user to close it.
//If you don't wait for user to close preview, you will see just a flash:
while HCalc.StillConnectedToApp() do
sleep(1000);
//User has manually closed the preview window at this point.
end;
//
V1.03:
*****************************
** Van Coppenolle Philippe **
*****************************
-Reformated code and renamed vars. with more TRY-EXCEPT zones, more robust.
-New function to encapsulate creation of OLE object ConnectToApp()
-Create admits new flag to reuse the last created instance of excel.
-NewDoc admits new flag to add or not a sheet to the new doc (related to the previous one).
-RemoveSheet added in 3 flavours: by index, byname, and all except one name.
-Added list of OLE constant for both Excel and OO so you can use them by name in your code.
-Added FontColor, Underline and HorizontalAlignment properties to cells.
Note: I added some properties so old vars names are still usable:
Document, ActiveSheet and Programa.
V1.02: Creating from a exiting file didn't set the AmericanFormat (thanxs Malte).
V1.01:
***********************
** By Malte Tüllmann **
***********************
-Excel2000/2003 save .xls files in a different way than 2007.
V1.00:
-Saving in Excel2007 will use Excel97 .xls file format instead of .xlsx
V0.99:
-Added a funtion by Alex Smith to set a cell text into italic.
V0.98:
-Added two procedures to easily send a number or a date to a cell position:
SendDate(Row, Col, Date) and SendNumber(Row, Col, Float), if you look at
the code you will notice that this is not so trivial as one could spect.
-I have added (as comments) some useful code found on forums (copy-paste rows)
V0.97:
-Added CellFormula(col, row), similar to CellText, but allows to set a cell
to a number wihout the efect of being considered by excel like a "text that
looks like a number" (doesn't affect OpenOffice). Use it like this:
CellFormula(1,1) := '=A2*23211.66';
Note1: Excel will always spect numbers in this shape: no thousand separator
and dot as decimal separator, regardless of your local configuration.
Note2: Date is also bad interpreted in Excel, in this case you can use
CellText but the date must be in american format: MM/DD/YYYY, if you
use other format, it will try to interpret as an american date and
only if it fails will use your local date format to "decode" it.
V0.96:
-Added PrintSheetsUntil(LastSheetName: string) -only works on excel- to print
out all tabs from 1 until -excluded- the one with the given name in such a
way that only one print job is created instead of one per tab (only way to do
this in previous versions, so converting part of a excel to a single PDF
using a printer like PDFCreator was not posible).
V0.95:
-ActivateSheetByIndex detect imposible index and allows to insert sheet 100 (it will create all necesary sheets)
-SaveDocAs added a second optional parameter for OOo to use Excel97 format (rescued from V0.93 by Rômulo)
-A little stronger ValidateSheetName() (filter away \ and " too).
V0.94:
-OpenOffice V2 compatible (small changes)
-A lot of "try except" to avoid silly errors.
-SaveDocAs(Name: string): boolean; (Added by Massimiliano Gozzi)
-New function FileName2URL(Name) to convert from FileName to URL (OOo SaveDosAs)
-New function ooCreateValue to hide all internals of OOo params creation
V0.93:
***************************
** By Rômulo Silva Ramos **
***************************
-FontSize(Row, Col, Size): change font size in that cell.
-BackgroundColor(row, col: integer; color:TColor);
-Add ValidateSheetName to validate sheet names when adding or renaming a sheet
REVERTED FUNCTIONS (not neccesary in newer version V0.95 anymore)
-Change AddNewSheet to add a new sheet in end at sheet list
*REVERTED IN V0.95*
It creates sheet following the active one, so to add at the end:
ActivateSheetByIndex(CountSheets);
AddNewSheet('Sheet '+IntToStr(CountSheets+1));
-Change in SaveDoc to use SaveAs/StoreAsUrl
*REVERTED V0.95*
Use SaveDocAs(Name, true) for StoreAsUrl in Excel97 format.
V0.92:
-SetActiveSheetName didn't change the name to the right sheet on OpenOffice.
-PrintPreview: New procedure to show up the print preview window.
-Bold(Row, Col): Make bold the text in that cell.
-ColumnWidth(col, width): To change a column width.
V0.91:
-NewDoc: New procedure for creating a blank doc (used in create)
-Create from empty doc adds a blank document and take visibility as parameter.
-New functions ooCreateValue and ooDispatch to clean up the code.
-ActiveSheetName: Now is a read-write property, not a read-only function.
-Visible: Now is a read-write property instead of a create param only.
V0.9:
-Create from empty doc now tries both programs (if OO fails try to use Excel).
-CellTextByName: Didn't work on Excel docs.
