create shared folder

PowerShell Help
1

Hello readers

I i’m working on a new function that will create a new folder and make it a share @ the same time.
Now i’m having a small problem when i try to create a share by WMI i get a return message what says "

21 Error 21: Invalid Parameter

i hope that some of you cant see what my problem is.
i think its about converting the 2 varible’s into 1 what gives me the problem.

BTW its my first code so if you have some tips as well feel free :slight_smile:

Function new-sharedfolder{
    [CmdletBinding()]
    param(
            [Parameter( Mandatory=$True,
                        valuefrompipeline=$True,
                        valuefrompipelinebypropertyname=$True)]
            [string[]]$folders,

            [parameter( Mandatory=$true)]
            [validatelength(1,1)]
            [string[]]$drive,
        
            [Parameter( Mandatory=$True)]
            [string[]]$users,

            [parameter (mandatory=$true)]
            [validateset("ReadAndExecute","Modify")]
            [string[]]$permission,

            [parameter()]
            [string[]]$computername = "localhost"
        )
    BEGIN{}

            }
            if ($folderstatus) {

You need to remove the quotes from your parameters in $share.Create.

i.e. This:

$Share.Create(“$sharepath, $folder, 0″)

should be written like this:

$Share.Create($sharepath, $folder, 0)

Oh, and if this is really your first script, you’re off to an absolutely fantastic start. :slight_smile:

thanks for the feedback that was the solution for my problem
i was afraid that the problem was this part of code

New-Variable sharepath -Value $drive":\"$folder

because of the mixture of 2 variables and flat text into one variable
