从Delphi修改Excel形状

Question

如何从Delphi中修改现有 excel形状的文本？

我可以创建一个新形状并设置其文本

procedure TForm1.Button1Click(Sender: TObject); 
var 
excel, xlShape : variant; 
begin 
olecontainer1.CreateObject('Excel.Application',false); 
excel := olecontainer1.OleObject; 
excel.workbooks.open('C:\test.xls'); 

XlShape := excel.application.worksheets[1].Shapes.AddShape(1, 0, 0, 450, 200); 
XlShape.textframe.characters.text:='new shape created from Delphi'; 

但是，如果形状已经存在，我怎么能选择它来改变其text属性？喜欢的东西：

excel.application.worksheets[1].Shapes('shape1').textframe.characters.text := 'This gives error'; 

Answer 1

试试这个代码

procedure TForm1.ButtonClick(Sender: TObject); 
var 
excel, xlShape : variant; 
begin 
olecontainer1.CreateObject('Excel.Application',false); 
excel := olecontainer1.OleObject; 
excel.workbooks.open('C:\test.xls'); 
XlShape:=excel.ActiveSheet.Shapes.Item(1);// or like this .Item('Rectangle 1'); 
if VarIsEmpty(xlShape) then 
begin 
XlShape := excel.application.worksheets[1].Shapes.AddShape(1, 0, 0, 450, 200); 
XlShape.textframe.characters.text:='new shape created from Delphi'; 
end 
else 
ShowMessage(XlShape.textframe.characters.text); 
excel.activeworkbook.close; 
xlShape:=Unassigned; 
excel:=Unassigned; 
OleContainer1.DestroyObject; 
end; 

Answer 2

XlShape := excel.application.worksheets[1].Shapes.AddShape(1, 0, 0, 450, 200); 
XlShape.Name := "mycustomshape"; 

所以，当你知道形状的名称，你可以参考它的名字

excel.application.worksheets[1].Shapes('mycustomshape').textframe.characters.text := 'This doesnt gives error'; 

或者，您可以使用索引来引用它（0基于）。我假设它是工作表中的第一个形状对象。

excel.application.worksheets[1].Shapes(0).textframe.characters.text := 'This doesnt gives error'; 

编辑：我不知道德尔福是如何在语法方面不同。
看看是否使用括号（而不是常规的支架）工作

excel.application.worksheets[1].Shapes['mycustomshape'].textframe.characters.text := 'This doesnt gives error'; 

OR

excel.application.worksheets[1].Shapes[0].textframe.characters.text := 'This doesnt gives error';
