How to set Spark Properties without losing user preferences (windows)

I wanted a way to set some properties with spark without overwriting the users preferences. Here is the solution I came up with.

There are a few assumptions made. First you have powershell install on the workstation, that spark.properties is in the same location for everyone.

create a powershell script with the following, and then run it at logon script via GPO.

$updates=@{

‘ssoEnabled’=‘true’

‘server’=‘xmppserver.com

‘autoLoginEnabled’=‘true’

‘toasterPopup’=‘true’

‘windowTakesFocus’=‘true’

}

(Get-Content $env:APPDATA\spark\spark.properties) |

ForEach-Object{

$key=$_.Split(’=’)[0]

if($val=$updates[$key]){

‘{0}={1}’ -f $key,$val

}else{

$_

}

} |

Set-Content $env:APPDATA\spark\spark.properties

That’s it. Hope this helps

It is not actually enforcing, as they can change it after the login. I have done it a while ago for Exodus properties file (xml) with a vbs script, can be applied to Spark:

Const ForReading = 1

Const ForWriting = 2

Set objFSO = CreateObject(“Scripting.FileSystemObject”)

Set objFolder = objFSO.GetFolder(“E:\Admin\Exodus”)

RepSubfolders objFolder

Sub RepSubFolders(Folder)

For Each Subfolder in Folder.SubFolders

Set objFile = objFSO.OpenTextFile(Subfolder & “\exodus.xml”, ForReading)

strText = objFile.ReadAll

objFile.Close

strNewText = Replace(strText, “192.168.12.41”, “jiveserver”)

Set objFile = objFSO.OpenTextFile(Subfolder & “\exodus.xml”, ForWriting)

objFile.WriteLine strNewText

objFile.Close

Set objFile = objFSO.OpenTextFile(Subfolder & “\exodus.xml”, ForReading)

strText = objFile.ReadAll

objFile.Close

strNewText = Replace(strText, “false”, “true”)

Set objFile = objFSO.OpenTextFile(Subfolder & “\exodus.xml”, ForWriting)

objFile.WriteLine strNewText

Next

End Sub

Well, in this vbs you have to know what the altered text is, so it won’t work in all scenarios probably.

You’re right, its not true enforcement, but I think it will get the job done for the most part. Maybe I should change the title up a bit!
