the prtscr works, but only when the application is active.

VB Code:
  1. Public Class Form1

  2.     Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer

  3.     Public Declare Function UnregisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer) As Integer

  4.     Public Const WM_HOTKEY As Integer = &H312

  5.  
  6.     Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)

  7.         If m.Msg = WM_HOTKEY Then

  8.             ' Pressed the hotkey!

  9.             PictureBox1.Image = Clipboard.GetImage()

  10.             Me.ShowInTaskbar = False

  11.             Me.WindowState = FormWindowState.Normal

  12.  
  13.         End If

  14.         MyBase.WndProc(m) '<-- Never Ever Forget This!

  15.     End Sub

  16.  
  17.     Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

  18.  
  19.         Me.ShowInTaskbar = True

  20.         Me.WindowState = FormWindowState.Minimized

  21.         RegisterHotKey(Me.Handle, 9, 0, 44)

  22.  
  23.     End Sub

  24.  
  25.     Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

  26.  
  27.         SaveFileDialog1.ShowDialog()

  28.         PictureBox1.Image.Save(SaveFileDialog1.FileName)

  29.     End Sub

  30.  
  31.  
  32.     Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

  33.         Call UnregisterHotKey(Me.Handle, 9) '<-- Don't forget this

  34.     End Sub

  35.  
  36.     Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

  37.         Call RegisterHotKey(Me.Handle, 9, 0, 44) '<-- Play with these settings

  38.     End Sub

  39. End Class

i have it so it minimizes, you press a key (prntscreen) then it takes the screenshot (using windows) and pastes it in the picture box. it goes back to normal windowed mode when prnt screen is pressed, but it doesnt actually prnt screen. Windows only prntscreens when my app is active. If im not making myself clear tell me and i will clarify
