Function Invoke-Process { <# .SYNOPSIS Execute a process with optional arguments, working directory, window style. .DESCRIPTION Executes a process, e.g. a file included in the Files directory of the App Deploy Toolkit, or a file on the local machine. Provides various options for handling the return codes (see Parameters). .PARAMETER Path Path to the file to be executed. If the file is located directly in the "Files" directory of the App Deploy Toolkit, only the file name needs to be specified. Otherwise, the full path of the file must be specified. If the files is in a subdirectory of "Files", use the "$dirFiles" variable as shown in the example. .PARAMETER Parameters Arguments to be passed to the executable .PARAMETER SecureParameters Hides all parameters passed to the executable from the Toolkit log file .PARAMETER WindowStyle Style of the window of the process executed. Options: Normal, Hidden, Maximized, Minimized. Default: Normal. Note: Not all processes honor the "Hidden" flag. If it it not working, then check the command line options for the process being executed to see it has a silent option. .PARAMETER CreateNoWindow Specifies whether the process should be started with a new window to contain it. Default is false. .PARAMETER WorkingDirectory The working directory used for executing the process. Defaults to the directory of the file being executed. .PARAMETER NoWait Immediately continue after executing the process. .PARAMETER PassThru Returns ExitCode, STDOut, and STDErr output from the process. .PARAMETER Asynchrounus Executes the process and grabs the standard output stream asynchrounusly. .PARAMETER Attach Only valid if Asynchrounus has been specified. This writes the standard output to the console during runtime of the process. .PARAMETER WaitForMsiExec Sometimes an EXE bootstrapper will launch an MSI install. In such cases, this variable will ensure that that this function waits for the msiexec engine to become available before starting the install. .PARAMETER MsiExecWaitTime Specify the length of time in seconds to wait for the msiexec engine to become available. Default: 600 seconds (10 minutes). .PARAMETER IgnoreExitCodes List the exit codes to ignore. .PARAMETER ContinueOnError Continue if an exit code is returned by the process that is not recognized by the App Deploy Toolkit. Default: $false. .EXAMPLE Invoke-SRProcess -Path 'uninstall_flash_player_64bit.exe' -Parameters '/uninstall' -WindowStyle 'Hidden' If the file is in the "Files" directory of the App Deploy Toolkit, only the file name needs to be specified. .EXAMPLE Invoke-SRProcess -Path "$dirFiles\Bin\setup.exe" -Parameters '/S' -WindowStyle 'Hidden' .EXAMPLE Invoke-SRProcess -Path 'setup.exe' -Parameters '/S' -IgnoreExitCodes '1,2' .EXAMPLE Invoke-SRProcess -Path 'setup.exe' -Parameters "-s -f2`"$configToolkitLogDir\$installName.log`"" Launch InstallShield "setup.exe" from the ".\Files" sub-directory and force log files to the logging folder. .EXAMPLE Invoke-SRProcess -Path 'setup.exe' -Parameters "/s /v`"ALLUSERS=1 /qn /L* \`"$configToolkitLogDir\$installName.log`"`"" Launch InstallShield "setup.exe" with embedded MSI and force log files to the logging folder. .NOTES .LINK http://psappdeploytoolkit.com #> [CmdletBinding()] Param ( [Parameter(Mandatory=$true)] [Alias('FilePath')] [ValidateNotNullorEmpty()] [string]$Path, [Parameter(Mandatory=$false)] [Alias('Arguments')] [ValidateNotNullorEmpty()] [string[]]$Parameters, [Parameter(Mandatory=$false)] [switch]$SecureParameters = $false, [Parameter(Mandatory=$false)] [ValidateSet('Normal','Hidden','Maximized','Minimized')] [Diagnostics.ProcessWindowStyle]$WindowStyle = 'Normal', [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [switch]$CreateNoWindow = $false, [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [switch]$Asynchronous = $false, [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [switch]$Attach = $false, [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [string]$WorkingDirectory, [Parameter(Mandatory=$false)] [switch]$NoWait = $false, [Parameter(Mandatory=$false)] [switch]$PassThru = $false, [Parameter(Mandatory=$false)] [switch]$WaitForMsiExec = $false, [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [timespan]$MsiExecWaitTime = $(New-TimeSpan -Seconds 800), [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [string]$IgnoreExitCodes, [Parameter(Mandatory=$false)] [ValidateNotNullorEmpty()] [boolean]$ContinueOnError = $false ) Begin { } Process { Try { $private:returnCode = $null ## Validate and find the fully qualified path for the $Path variable.
