Method for getting WinForm Control associated with the focused window:

System.Windows.Forms.MessageBox (WinForms)

An example of this that I have encountered is using the FarPoint Spread 3.0/6.0 ActiveX controls. These controls will throw a Runtime protected memory violation exception if they are hosted in a WinForms Form, instantiated and then the Form.MDIParent property is set to an MDI container Form but using the SetParent(childForm.Handle, Me.Handle) call works.

static extern TODO WinForm(TODO);

Declare Function WinForm Lib "user32.dll" (TODO) As TODO

• In WinForms: [System.Windows.Forms.PowerStatus]

Consider a Winform application with a OpenFileDialog that helps pick some file. This is then passed to the ExtractAssociatedIcon method to get the icon and display in a picture box.
