I try it, but even the simple code below doesn't work and I dont understand why:

use strict;
# Create Chart
use Win32::OLE;
use Win32::OLE::Const 'Microsoft Excel';
my $Excel = Win32::OLE->new("Excel.Application");
$Excel->{Visible} = 1;

#my $Book = $Excel->Workbooks->Add;
my $Workbook = "Auswertung022004.xls";
my $activeWorkbook = $Excel->Workbooks->Open($Workbook);

my $Sheet = $activeWorkbook->Worksheets("INF2");
[download]

The Error Message is:

Can't call method "Worksheets" on an undefined value at H:\work\Auswer
+tungen\ExcelChartWrite.pl line 14.
[download]

I would try to activate a Worksheet, even if I replace "INF2" with 1 (which should be the first sheet) the same Error Message shows up, what did I wrong?

Even if I put the line out, the Excel File Closes imediatly, Because of that it would be much easier to simply put the macro into the Excel file, because the macro has been debuged and runns propperly
