Powershell: Error while calling the SaveAs Method of some Office Applications

1 Comment

Hi,

if you tried to save a word or excel document as another format you got an error. For example, if you want to convert a CSV File to a Excel workbook and save it in Excel 95/97/2003 format.

[reflection.assembly]::LoadWithPartialName("Microsoft.Office.InterOp.Excel")
$oExcel = New-Object -ComObject "Excel.Application"
$sCSVFile="D:\temp\ImportFile.csv"
$oExcel.Visible = $true
$oCSVWorkbook=$oExcel.Workbooks.Add()
$oExcel.Workbooks.OpenText($sCSVFile)
$oCSVWorkbook.SaveAs("D:\temp\test.xls",[Microsoft.Office.Interop.Excel.XlFileFormat]::xlExcel9795)
Exception calling "SaveAs" with "1" argument(s): "SaveAs method of Workbook class failed"
At D:\test\CSV2Excel.ps1:29 char:20
+ $xl_workbook.SaveAs <<<< ("D:\Temp\test.xls")
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ComMethodTargetInvocation

Virtualbox: Creating and controlling Virtual Maschines from command line

Leave a comment

Hi,

VirtualBox offers a very powerful command inferface: vboxmanage. With vboxmanage you can create new virtual machine, add and modify harddisk and much more. All the things you could do in the GUI, and a lot more are also possible at command line. In this post I will create, modify, control and delete a complete virtual machine.

At the bottom of the post the whole script can be downloaded.
I used a debian linux system for my tests. To install the latest VirtualBox version use the following commands:

echo "deb http://download.virtualbox.org/virtualbox/debian wheezy contrib non-free" >> /etc/apt/sources.list
# Add Oracle Keyring
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | apt-key add -
# Update repositories
apt-get update
# Install latest virtualbox version
apt-get -y install virtualbox-4.3
# Installing the Extentionpack for USB2 and RDP support
wget http://download.virtualbox.org/virtualbox/4.3.6/Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack
VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack
