Sample code
The following sample code hides the Visio application window and, after a short pause, restores it. Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Place the following code in a new module: 'Set ShowWindow API constants. Public Const SW_HIDE = 0 Public Const SW_RESTORE = 1

'Declare ShowWindow API. Public Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long Place the following code in the "ThisDocument" module: Public Sub Hide Dim i As Integer Dim VisioHandle As Long 'Get a Visio handle. VisioHandle = Visio.Application.WindowHandle32 'Call the ShowWindow API to hide the Visio application window. Call ShowWindow(VisioHandle, SW_HIDE) 'Pause. For i = 1 To 2000 Debug.Print i  Next i   'Call the ShowWindow API to restore the Visio application window. Call ShowWindow(VisioHandle, SW_RESTORE) End Sub You can also use the ShowWindow API to minimize and maximize the Visio application window. The following example sets the ShowWindow API constants so that your Visual Basic for Applications code can control the state of the Visio application window: (Optional) Place the following code in a new module: Public Const SW_HIDE = 0 Public Const SW_NORMAL = 1 Public Const SW_SHOWMINIMIZED = 2 Public Const SW_SHOWMAXIMIZED = 3 Public Const SW_MAXIMIZE = 3 Public Const SW_SHOW = 5 Public Const SW_MINIMIZE = 6 Public Const SW_RESTORE = 9 Public Const SW_SHOWDEFAULT = 10 For more information about the ShowWindow API, refer to the Windows API documentation at the following Microsoft Web site:
