Hello, As a disclaimer I am not at all familiar with Win32 development. I was wondering if there was any way to automate control input to a GUI application if that application is minimized. Most automation tools I have seen specifically use coordinate offsets from the window (tlx,tly). I don't need a testing framework, I simply want ...
This question is pretty simple, but I'm not seeing why the code isn't working? Here's how I set the members of a ComboBox I have on my form: private void LoadUsersToComboBox() { ScansEntities3 db = new ScansEntities3(); comboBox1.DataSource = db.People; comboBox1.DisplayMember = "Name"; comboBox1.ValueMember = "ID"; } ...

When clicking on the application's taskbar entry, the form shows up but does not restore to the previous size. The form is reduced to just showing the title bar and the borders, w/o the client area. I tried listening for WM_SIZ...

Here's the documentation. I haven't found any explanation anywhere. There is a data binding overview but is for WPF, and I'm using WinForms. I thought what it does is to call whatever method I assign to the event Format of the Binding class, but it will call it even if I set formattingEnabled to false as long as I assign a method. So now...
