String Manipulation–Custom Problem

I just received an email that an IT Pro out on the internet posted a comment to my article on How to specify the number of decimal places in PowerShell Output. This was a bit more of a detailed response so I’m posting it as a blog article.

His issue was that we is presented with a string of numbers. The string contains sets of nine numbers. The first 7 represented dollars and the last 2 of each set represented cents. He needed a total. We just finished talking about string manipulation in class so I went at it. Here you go Matt!

# Starting Data

$Data = "000000025000001000000283711000025000037000054000000017"

# Determine the number of records in the string.

$MaxItems = $Data.length/9

$Total = 0

# Loop the number of records.

For($X=0; $X -lt $MaxItems; $X++)

{

# Use the SubString method of System.String

# to extract 9 characters at a time.

$D = $Data.Substring($X*9,9)

# use the first 7 characters as the dollar value.

[int]$Dollars = $D.Remove(7,2)

# Use the last 2 characters as the cents value.

[int]$Cents = $D.Remove(0,7)

# Add the 2 to get the total.

[Single]$Total += $dollars + $cents/100

# Output the object to the pipeline.

$Obj = New-Object -TypeName PSObject -Property @{

Dollars = $Dollars

Cents = $Cents

}

Write-Output $Obj

}

# Write the Total.

Write-Output $Total

Error icon when creating a GPO Preference drive map

You may not have an error at all. Take a look at the drive mapping below. The red triangle is what threw us off. It is not an error. It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle. This action will delete and recreate mapped drives for users. The net result of the Replace action is to overwrite all existing settings associated with the mapped drive. If the drive mapping does not exist, then the Replace action creates a new drive mapping. Update Action The Update action will have a yellow triangle. Update will modify settings of an existing mapped drive for users.
