I have a borderless WinForms app. The main window creates other forms (simple dialogs where I can click yes or no) with ShowDialog(). Every created dialog is not visible in the taskbar, my app has only one taskbar entry that focuses my app (and if a dialog is open that one is focused). If I use ALT+TAB to cycle to all open windows I onl...
I created a WPF Window and made it a MEF Export. I can do a ShowDialog once on the MEF Import but the second time it aborts because the MEF component was closed by the first ShowDialog. What can be done to allow repeats of ShowDialog? ...

When the application starts, first an OpenFileDialog is used to select a file. Then, a dialog box is shown using Showdialog() with some options for how the selected file should be processed. Finally...

I have three forms: A, B and C. Upon a button being clicked, A displays B. Similarly, B displays C. Both using the ShowDialog() method. However when I use the Hide() method (inside a Button Click event) on form C to close it, form B also closes. Why would this be? As far as I can see, it shouldn't be doing this. I certainly didn't wri...

When the phone has no wifi signal, the program crashes at builder.create() (see code below). However, when there...
I have a ShowDialog that takes several parameters. Is there a way to also pass it a delegate to handle an event on the parent form?

The original form is locked until I close the newly opened form. How do I open both forms so that the previous form can be at the very least moved around and given focus to? Within the mainForm, the...

Hello everyone! I'm trying to create a custom MessageBox by using a WPF Window that is called with ShowDialog(). So far, I've managed to implement everything, except for one thing. As you know, when you use MessageBox.Show("text"); you cannot set the focus or click the parent window (the one that called the MessageBox). If you do try ...
