SYMPTOMS
In Microsoft Excel version 5.0, if you try to use the OnWindow Property of the Window Object with an Info Window, you will receive the following run-time error message:

Windows method of Application class failed



WORKAROUND
To avoid this error message, use another method to simulate the OnWindow property. Below is an example subroutine to accomplish this. The first subroutine will run the InfoCheck macro whenever you switch to a different window. The InfoCheck subroutine will check and see if the active window is an Info Window by looking at the Caption.

To test this example, enter the subroutines below on a new module sheet then position the cursor in the Sub WinSwitch line and either press the F5 key or choose Start from the Run menu. After running the subroutine, if you display or switch to an Info Window, a message box will be displayed. Sub WinSwitch 'runs InfoCheck whenever you switch windows Application.OnWindow = "InfoCheck" End Sub

Sub InfoCheck 'checks to see if the Window Caption contains Info: 'if so a message box is displayed If Left(ActiveWindow.Caption, 5) = "Info:" Then Msgbox "This is an Info Window" End If End Sub



MORE INFORMATION
The OnWindow Property will run a specified procedure whenever you switch to a window. For example, you could use the following subroutine to run the message subroutine whenever you switch to Book2: Sub WinSwitch Application.Windows("Book2").OnWindow = "message" End Sub However, this property will not work correctly with an Info Window. For example, the following subroutine will return the error message "Windows method of application class failed": Sub InfoSwitch Application.Windows("Info: [Book2]Sheet1").OnWindow ="message" End Sub Microsoft provides examples of Visual Basic for Applications procedures for illustration only, without warranty either expressed or implied, including, but not limited to the implied warranties of merchantability and/or fitness for a particular purpose.
