Tips&Tricks: Excel Automation

I notice that in this forum (and not only ther) the same questions and problems concerning Excel automation are being asked over and over again. So let me share some of my experience with you:

--- DECLARATION ---
Name DataType Subtype Length
xlWorkbooks Automation 'Microsoft Excel 9.0 Object Library'.Workbooks
xlWorksheet Automation 'Microsoft Excel 9.0 Object Library'.Worksheet
xlWorksheetTemp Automation 'Microsoft Excel 9.0 Object Library'.Worksheet
xlApplication Automation 'Microsoft Excel 9.0 Object Library'.Application
xlRange Automation 'Microsoft Excel 9.0 Object Library'.Range
xlWorkbook Automation 'Microsoft Excel 9.0 Object Library'.Workbook
xlBorders Automation 'Microsoft Excel 9.0 Object Library'.Borders
xlHPageBreaks Automation 'Microsoft Excel 9.0 Object Library'.HPageBreaks
xlSheets Automation 'Microsoft Excel 9.0 Object Library'.Sheets

--- OPEN EXCEL ---
CLEAR(xlApplication);
CLEAR(xlRange);
CLEAR(xlWorkbooks);
CLEAR(xlWorkbook);
CLEAR(xlRange);
CLEAR(xlSheets);
CLEAR(xlWorksheet);
CLEAR(xlBorders);

IF CREATE(xlApplication, FALSE) THEN BEGIN // Param FALSE: If excel already started, use existing instance
xlApplication.SheetsInNewWorkbook := 1;
xlApplication.ScreenUpdating(FALSE); //RE01.02


--- note:
{At this point you have two possibilities:
1.Keep Excel visible and update the screen as long as you are developing. This considerably slows down exceution time but you always see what's going on. In case of the crash you know what has been done last and you can close Excel manually}
xlApplication.Visible(TRUE);
xlApplication.ScreenUpdating(TRUE);

{2. If your application is tested, you can turn Excel off while Navision is sending data. This will double the speed of execution. However, if an error occurs, Excel will still be instantiated but will not be visible in the taskbar. Pressing Ctrl-Alt-Del and killing the task will be your only option.
xlApplication.ScreenUpdating(FALSE);
xlApplication.Visible(FALSE);
---

xlWorkbooks := xlApplication.Workbooks;
END
ELSE
ERROR('Could not start Excel');


Procedure OpenExistingXlsWorkbook(FName : Text[250],SheetNr : Integer);

xlWorkbooks := xlApplication.Workbooks;
WorksheetAlreadyOpen := FALSE; // this is a local variable
IF xlWorkbooks.Count > 0 THEN BEGIN
ThisWorkbook := xlApplication.ActiveWorkbook;
WorksheetAlreadyOpen := (ThisWorkbook.FullName = FName);
END;
IF NOT WorksheetAlreadyOpen THEN
xlWorkbooks.Open(FName);
xlWorkbook := xlApplication.ActiveWorkbook;
xlSheets := xlWorkbook.Worksheets;
xlWorksheet := xlSheets.Item(SheetNr);

--- note: A preferred method of mine is to use an existing Excel Book as Template where the user can
define Titles, Layout etc. as he wishes. My application then reads this template file, fills in the data and saves the result under a different name. The above code with "WorksheetAlreadyOpen" makes sure that the Template Book is not being opened twice.

Procedure XlsNewWorkBook (WName : Text[20]);

xlWorkbooks.Add;
xlWorkbook := xlApplication.ActiveWorkbook;
xlWorksheet := xlApplication.ActiveSheet;
xlWorksheet.Name := Name;


--- SAVE EXCEL WORKSHEET ---
Procedure XlsSaveAs(FName : Text[250]);

IF xlWorkbook.FullName = FName THEN // Same filename
xlWorkbook.Save
ELSE BEGIN
IF FILE.EXISTS(FName) THEN // Forced overwrite, in case the File already exists!
IF ERASE(FName) THEN;
xlWorkbook.SaveAs(FName);
END;

--- CLOSE EXCEL ---
Procedure CloseExcel (Action : Option (Visible,PrintAndQuit,Quit));

Case Action of
Action::Visible: Begin
xlApplication.ScreenUpdating(TRUE);
xlApplication.Visible(TRUE);
End;
Action::PrintAndQuit : Begin
xlApplication.ScreenUpdating(TRUE); //force Recalculation
xlWorkbook.PrintOut;
x
With best regards from Switzerland

    Example:

    CREATE(Winword); // start Word
    Winword.Documents.Add; // new blank page
    // Winword.Visible(TRUE); // only for testing, because it is very slow

    OnAfterGetRecord()
    zeile (name);
    zeile (Adress);
    leerzeile(1);
    zeile ("PLZ Code" + ' ' + Ort);

    // picture
    IF Bild.HASVALUE THEN BEGIN
    Bild.EXPORT('c:\'+"Nr."+'.bmp');
    Save1:= FALSE; // linkToFile:=False
    save2:= TRUE; // SaveWithDocument:=True
    Winword.Selection.InlineShapes.AddPicture('c:\'+"Nr."+'.bmp',Save1,save2);
    END;

    Winword.Selection.InsertBreak; // new page

    OnPostDataItem()
    Winword.Visible(TRUE); // Winword visible
    Winword.Activate; // Winword aktiv

    zeile(text : Text[250])
    Winword.Selection.TypeText(text); // Zeile schreiben
    leerzeile(1);

    leerzeile(Anzahl : Integer)
    FOR i := 1 TO Anzahl DO
    Winword.Selection.TypeParagraph; // space-lines

    And after all don't forget to CLEAR all instancies, or the excell.exe will be still running on the "Background".

    Another way of checking if a Automation variable is created is:
    IF ISCLEAR(autAutomationVariable) THEN BEGIN
      CREATE(autAutomationVariable);
    END;
    
    ...
    
    CLEAR(autAutomationVariable);
    
    Now, let's see what we can see.

    Everybody on-line.

    Looking good!

    Hi there,

    I have created a program to export to excel using excel buffer. Now the client wants me to add a logo to the document header.

    How can I keep my original report while adding a logo to the header?

    I've tried :
    XlWorkSheet.PageSetup.LeftHeaderPicture.Filename := 'C:\picture.BMP'
    which didn't work..

    Then
    XlWorkSheet.Pictures.Insert('C:\picture.BMP')
    which couldn't compile...

    Only succeeded with
    XlWorkSheet.SetBackgroundPicture('C:\picture.BMP');
    which is not what I want!

    ](*,) I'm very new to all this automation programming. Pls give a hint or two.

    Thanks in advance.

    I dont use the Excel Buffer, but the code that works for me is:

    Book:=Excel.Workbooks.Add(-4167);
    Sheet:=Excel.ActiveSheet;
    xlWorksheet.PageSetup.CenterHeaderPicture.Filename := 'C:\Header.bmp';
    Sheet.PageSetup.CenterHeaderPicture.Height := 197;
    Sheet.PageSetup.CenterHeaderPicture.Width := 418;
    Sheet.PageSetup.CenterHeaderPicture.Brightness := 0.36;
    Sheet.PageSetup.CenterHeaderPicture.ColorType := 1;
    Sheet.PageSetup.CenterHeaderPicture.Contrast := 0.39;
    Sheet.PageSetup.CenterHeaderPicture.CropBottom := 0;
    Sheet.PageSetup.CenterHeaderPicture.CropLeft := 0;
    Sheet.PageSetup.CenterHeaderPicture.CropRight := 0;
    Sheet.PageSetup.CenterHeaderPicture.CropTop := 0;
    Sheet.PageSetup.CenterHeader := '&G';

    Note: You will have to press Print Preview to view the logo.

    PS: Anyone knows how to insert a row into Excel at a given place?

    Selection.EntireRow.Insert

    I think the selection object is part of the application object but I'm not sure, try AppVariable.Selection.EntireRow.Insert or SheetVariable.Selection.EntireRow.Insert. This only inserts a blank row mind, so you will have to put your data into this row after inserting it. You will have to move the cursor to the desired row first too.

    This is nice work to put data out to Excel or Word.
    But what about the other way around?

    Any Hints and tricks to get Data out of excel into Navision by C/AL code?
    regards,
    Michael Schumacher

    oh, what day is it? Backup day. OK, let's dump all data to /dev/nul ;-)
  • zarrynzarryn Member Posts: 29
    Take a look at the Industry Template tool in 3.70B. It has a utility that will take data from Excel and insert in Navision. The key pieces are Table 8601 Mapping Header, Table 8602 Mapping Lines and Codeunit 8601 Mapping Handle. Hope this helps.

    I don't think fabian is posting anymore, since his last post is of 2001. :(

    You can have a look at Table 370 for excel automation examples or ask a question about the specific command you need.
  • garakgarak Member Posts: 3,263
    There is an easy way to find out which Classes you must add as variable to get the positive result.

    Start our M$ Office Application. For example Word. Then starts the Macrofunction. Then do that what Navision should be do. When you finished, stop the Macrorecording. Then take a look into the VBA-Code. Here you can see the results an the "Automations" do you need.

    Also take a look into the Office Outomation Strukture (The Struckture Tree).

    So you can finish you Navisioncode faster (its my experience.

    Regards
    Do you make it right, it works too!

    Try to shorten your Automation variable (for example: XLAppl).

    Hi
  • Luc_VanDyckLuc_VanDyck Member, Moderator, Administrator Posts: 3,633
    If you don't know how to use it, why do you create that variable in the first place? I never worked with this PIVOTTABLE-thing, so I'm afraid I can't help you out here.
