A number of parameters for EMS (the Exchange Management Shell - which is just PowerShell v1 plus the Exchange snap-ins) require the specification of a multivalued property.

Some things are just very easy in PowerShell. It's great! Here is a true quickie - rename and reboot a computer system (including a remote computer!): function renameAndReboot([string]$computer, [string]$newname) { $comp = gwmi win32_computersystem -computer $computer $os = gwmi win32_operatingsystem...

In Part 1 of this mini-series I presented the beginnings of a database layer supporting three different database architectures, that could easily be extended to handle more database engines. In Part 2 we built on Part 1 and discussed variable handling techniques. In this article, Part 3, we'll build...

I've recently had need to be able to access data contained in three different database platforms: Microsoft Access, Microsoft SQL Server, and Mysql AB's MySQL. Originally, I thought this was going to be a tough thing to do, but it turned out to be pretty easy. ODBC drivers are available for all...

Truthfully, doing it manually isn't difficult. But, like...
