How to switch between windows and do treatments on it??? Is there a basic function in blue Prism ?   I tried several codes: In Initializes: Public Class PInvoke                 Public Shared Function ShowWindow (ByVal hwnd As IntPtr, ByVal nCmdShow As Integer) As Boolean                 End Function                 Public Shared Function SetForegroundWindow(ByVal hwnd2 As IntPtr) As Boolean                 End Function End Class Public Declare Function BringWindowToTop Lib "user32" (ByVal hwnd As IntPtr) As Boolean   Object code: PInvoke.ShowWindow(hWnd, nCmdShow) with hWnd the process ID and nCmdShow (https://msdn.microsoft.com/fr-fr/library/windows/desktop/ms633548(v=vs.85).aspx)   But the ShowWindow or BringWindowToTop  or SetForegroundWindow function does not seem to do anything, PB goes through the box but nothing happens.   Helppp!     Thu, 26 Jul 2018 18:24:00 GMT https://community.blueprism.com/t5/Product-Forum/How-show-window/m-p/57264#M11294 BordessoullesVi 2018-07-26T18:24:00Z https://community.blueprism.com/t5/Product-Forum/How-show-window/m-p/57265#M11295 Ok I found a solution The problem comes from the hWind function of the ShowWindow function (hWnd, nCmdShow). You should not use the Process Id of the window but use the ""handle of the window"" (use the FindWindow function).   But is there a basic function in blue Prism that does this (change active window) ?
