How to use the OpenFileDialog Control with SAPIEN PowerShell Studio

Developing advanced GUIs is a neat way to expand your PowerShell coding capability.  Traditionally, we would have to learn a different programming language to do this.  That means you would have to learn PowerShell for your day-to-day tasks and something like C+ or .NET to crate the GUI.  After teaching PowerShell for the last 7 years, I know that IT Pros do not want to have to learn multiple languages.  With SAPIEN PowerShell Studio, you can leverage your PowerShell skill set in a visual environment.

Today we are going to take a very simplistic view on how to graphically select files on your hard drive. First, create a simple form with these three controls.  Button, Label, OpenFileDialog.  The first two will appear on your form but the OpenFileDialog will appear below the form because it will open in a new window when called.

Next, add the Click event to the button and then add this code: (Remember to add the event by right clicking button1 and selecting edit default event.  Just typing lines 7 and 12 will not register the event.)


We left all of the control names at their defaults for simplicity.  Line 9 will open the file browser.  Line 10 will display what you selected in the label.

Here we go!


Click on button1



Select a file and click OK.


The name of the selected file is stored in the FileName property of the $openfiledialog object.



Nice and easy!!!

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. This action differs from Replace in that it only updates settings defined within the preference item. All other settings remain as configured on the ma...
