I try to embed an image (jpg or bmp) into a spreadsheet. It will go in the top left 
of the spreadsheet - like a letterhead, sort of. I've seen the methods that use 
late binding, but the code I'm modifying use the early binding object 
TExcelApplication (the instance is called ExcelApplication1). The following doesn't 
compile:

ExcelApplication1.ActiveSheet.Pictures.Insert('c:\translogo.bmp')

I get the error "undeclared identifier: Pictures". Any suggestions?

Answer:

If WS is your worksheet:

1   { ... }
2   WS.Shapes.AddPicture('C:\Pictures\Small.Bmp', EmptyParam, EmptyParam, 10, 160,
3     EmptyParam, EmptyParam);


or

4   { ... }
5   var
6     Pics: Excel2000.Pictures; {or whichever Excel}
7     Pic: Excel2000.Picture;
8     Pic: Excel2000.Shape;
9     Left, Top: integer;
10  { ... }
11  Pics := (WS.Pictures(EmptyParam, 0) as Pictures);
12  Pic := Pics.Insert('C:\Pictures\Small.Bmp', EmptyParam);
13  Pic.Top := WS.Range['D4', 'D4'].Top;
14  Pic.Left := WS.Range['D4', 'D4'].Left;
15  { ... }


EmptyParam a special variant (declared in Variants.pas in D6+). However in later 
versions of Delphi some conversions cause problems. This should work:

16  uses
17    OfficeXP;
18  
19  { ... }
20  WS.Shapes.AddPicture('H:\Pictures\Game\Hills.bmp', msoFalse, msoTrue, 10, 160, 100,
21    100);


But you may have to use a TBitmap to find out how large the picture should be.
