PowerShell Messagebox

messageboxRecently I posted an article explaining how to create a popup box in PowerShell using the Wscript.Shell COM object from our VBScript days. That was something I presented at the PowerShell Summit. Another option is a MessageBox, again like we used to use in VBScript. This works very much like the popup except the user has to click a button to dismiss the box. I can’t think of a compelling reason why you would choose one technique over the other if you need the user to click something. But I’ll let you make that call. Here’s the function, New-Messagebox.

Most of the function is a wrapper around this line:

Like the popup function, I wanted to make it easier to create a messagebox without having to remember the names for buttons and icons so I use validation sets with my parameters. This makes it much easier to create a command like this in your script:

In the version I presented at the PowerShell Summit, the function did not write anything to the pipeline unless you used -Passthru. After thinking about it more, I realized the whole reason you are likely to use a MessageBox is to capture an interaction so I flipped the parameter and now it is -NoPassthru. Now, when the user clicks a button, the text value of that button is automatically written to the pipeline. If you include -NoPassthru you’ll get nothing. Here’s an example:


Because the messagebox writes text to the pipeline, it is a little easier to use than the Popup technique where you have to decode an integer value. In any event, you now have some options.

If you find this useful, I hope you’ll let me know.

Friday Fun – Snappy Shortcuts

In one of my recent Prof. PowerShell columns, I wrote about using the Wscript.Shell VBScript object in PowerShell to retrieve special folder paths. Another handy trick is the ability to create shortcut links to either file or web resources. Let me show you how to accomplish this in PowerShell and why you might want to.

This Old Script

I’m very slowly revising my main web site. The upshot for now is that there is no direct link to my old script library. Many of my Mr. Roboto tools can be found on this page. Until I can finish the upgrade project, you can use this link, http://www.jdhitsolutions.com/scripts.htm to take you directly to the old page.  Enjoy.
