To open the form, you just call its function. In addition, PowerShell Studio makes it really easy to open any form from any other form in the project by enclosing each form in a reference function that's available to all files in the project. The DialogResult indicates which button was used to close the child form.

You do not need to add any code to reopen the parent form. Also, when you close the child form, the method that opened it ( ShowDialog()) returns the DialogResult of the child form to the parent form. We say that "control is passed to the child form." Then, when the child form closes, control is automatically passed to its parent form, which is reenabled. When you open a child form in a modal window structure, its parent form is temporarily disabled. The child form can then open other forms, so it becomes the parent of another child form. The starting form is called the main form or parent form or owner, and window that's opened is called the child form. In a form project with modal windows, one form opens another form. Your browser does not support HTML5 video. (For an explanation of how these features work, see How Do Multi-Form Projects Work?) Instead, it's the conveniences that PowerShell studio adds, including wrapping forms in functions and making critical property values of the controls on each form easily accessible to the other form. The cool part of this exercise is not the functionality of the UI, which is quite limited.
When you type a message in the text box on the child form, and then click OK, the child form closes and the message that you typed appears in the text box on the main form. When you click the Open Child Form button on the main form, the child form opens. This little app starts with a main or parent form.

But, to show you how to work with multiple forms, I want to start with a really simple example. It can be as simple as an app that launches a message box or as complex as a dozen-page wizard that collects a significant amount of data. So, here's one for my friends in Austin! What's a Multi-Form App?Ī multi-form or multi-page app is a GUI application with more than one window.
A few of the questions were focused on the DialogResult property of forms and I realized that I didn't have a simple example of a multi-part form. The attendees asked terrific questions - really insightful - and we had a great time. (Learning to write GUI apps? PowerShell GUIs: Where do I start?) This is a weird exercise for PowerShell folks who are used to linear programming of scripts that run in a console. This month, we were enjoying my Thinking in Events hands-on lab, where we build a PowerShell GUI and wrap it in an exe. And, Austin is home to whole slew of computing powers, including Facebook, Dell, IBM, AMD, 3M, and the famous University of Texas at Austin. I had a great time in Austin, Texas (yes, Austin is still in Texas) last week with the Austin PowerShell User Group ( Founded by Thom Schumacher and now admirably led by Aditi Satam, this awesome group serves PowerShell folks in the whole Austin metro area. Otherwise, start with the My First Form videos ( Part 1: Build a Simple PowerShell GUI App and Part 2: Controls and Properties) and read the beginner blogs in PowerShell GUIs: Where do I start? In this blog, we assume that you know how to create a single-form PowerShell GUI app or that you've participated in a Thinking in Events hands-on lab. If you prefer a video, see Create a Muiti-Form PowerShell GUI App (video). When you finish, you'll know how to use the basic multi-form features of PowerShell Studio.įor details about how these features work under the covers, see How Do Multi-Form Projects Work? If you get stuck, the code for this project is on GitHub. The app consists of a parent form that gets data from a child form and displays it. This step-by-step example shows you how to create a very simple multi-form PowerShell GUI app. User Rating: 4 / 5 Please Rate Tested on: PowerShell 2.0+, PowerShell Studio 2016 Please refer to the following blog articles for more details on how to use the Function Builder / Parameter Builder: When you are done editing the parameters, it will produce a parameter block for your script: Just like the Function Builder, you can specify the parameters, parameter sets, validation, and help comments: You can access the Parameter Builder using the Ribbon: You can use the Parameter Builder to insert a new parameter block or edit existing script parameters. Otherwise the Parameter Builder and the Function Builder share the same functionality. Those familiar with the Function Builder will recognize the similarities between the two tools, with the exception of the Name portion of the builder.
With the v4.2.85 service release of PowerShell Studio 2015 we introduced the new Parameter Builder.
If you have used PowerShell Studio’s Function Builder chances are probably you wished it could edit your script parameters.
