Powershell: A text based menu

8 Comments

Hi,

a long time ago I wrote a Menu function for quickly choose predefined options in a script. An example

Source the menu.ps1 in your script and call  fShowMenu. This will show the menu. The function needs 2 parameters:
Parameter 1: The menu title as string
Parameter 2: A hashtable with the Menuentries. The key of an Menuitem is returned by the function the corresponding value is shown at the menu.

# Source the file
. .\menu.ps1
# Call Menu funtion
fShowMenu "Choose your favorite Band" @{"sl"="Slayer";"me"="Metallica";"ex"="Exodus";"an"="Anthrax"}

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

Windows: Powershell script to fix and repair WMI

6 Comments

Hi,

this script repairs and recreates the WMI Repository of a Windows. For example, this occurs sometimes if you clone a Windows machine with an installed SCCM/SMS Client. The typical error in this case is “Failed to open to WMI namespace ‘\\.\root\CCM\SoftwareUpdates\DeploymentAgent’ (8007045b)”

Lasts start. Start a Powershell console as Administrator. Stop all services. Sometimes other services depends on the WMI Service and does not accept a stop request. Therefore you cannot stop the WMI service. TrendMicro Office is such a service. You have to kill them by TaskManager.

# Stop WMI
# Only if SCCM/SMS Client is installed. Stop ccmexec.
Stop-Service -Force ccmexec -ErrorAction SilentlyContinue
Stop-Service -Force winmgmt

(Re)Register WMI binary components

[String[]]$aWMIBinaries=@("unsecapp.exe","wmiadap.exe","wmiapsrv.exe","wmiprvse.exe","scrcons.exe")
foreach ($sWMIPath in @(($ENV:SystemRoot+"\System32\wbem"),($ENV:SystemRoot+"\SysWOW64\wbem"))){
	if(Test-Path -Path $sWMIPath){
		push-Location $sWMIPath
		foreach($sBin in $aWMIBinaries){
			if(Test-Path -Path $sBin){
				$oCurrentBin=Get-Item -Path  $sBin
				Write-Host " Register $sBin"
				& $oCurrentBin.FullName /RegServer
			}
			else{
				# Warning only for System32
				if($sWMIPath -eq $ENV:SystemRoot+"\System32\wbem"){
					Write-Warning "File $sBin not found!"
				}
			}
		}
		Pop-Location
	}
}

Powershell: Check for Administrator rights

Leave a comment

Hi,

for a lot of powershell scripts Administrator permissions are necessary. In powershell, you can check if you are elevated by the following script code.
Insert the snippet at the top of your script. It checks the credentials and exits the script if the administrator permissions are missing.
