In my GUI I use a MaskedTextBox for IPv4 addresses, with mask: 990.990.990.990
The function below can help you to 'align' an IP address into a MaskedTextbox.
I would like to share this little function with you all.
Enjoy.
PowerShell Code
Double-click the code block to select all.Function Format-IpV4AddressMaskedTextBox { <# .SYNOPSIS Formats an IPv4 text string for a MaskedTextBox. .OUTPUTS String. A MaskedTextBox-formatted IpV4 text. .EXAMPLE PS C:\> Write-Host (WsApp-Format-IpV4Address -IpV4Address '10.230.12.5' -FillCharacter '_') PS C:\> _10.230._12.__5 PS C:\> Write-Host (WsApp-Format-IpV4Address -IpV4Address '1.1.1.1' -FillCharacter '0') PS C:\> 001.001.001.001 #> Param( [String]$IpV4Address, [Char]$FillCharacter = ' ' ) # Return untouched. If ([String]::IsNullOrWhiteSpace($IpV4Address)) { Return $IpV4Address } [Array]$Private:newIp = @() # Split the IP address and add leading spaces. ForEach ($Private:number In ($IpV4Address -split [RegEx]::Escape('.'))) { $newIp += $number.PadLeft(3, $FillCharacter) } Return ($newIp -join '.') }
