    Get Screen Data With an Excel Macro
    In This Topic

    You can use an Excel Macro to get data from a terminal screen and put it into a spreadsheet.

    This sample uses the GetText method to get data from a session.

    This article contains tabbed content that is specific to each terminal type. Be sure the tab for your terminal type is selected.

    To run this sample

    1. On the Excel VBA Editor Tools menu, select References and then select the following Reflection Libraries:
    • Attachmate_Reflection_Objects
    • Attachmate_Reflection_Objects_Emulation_IbmHosts
    • Attachmate_Reflection_Objects_Framework
    1. Copy the following code into an Excel Sheet object code window and then press F5 to run the macro.

    Copy Code 
    Public WithEvents screen As Attachmate_Reflection_Objects_Emulation_IbmHosts.ibmScreen
Public Sub GetDataFromIBMScreen()
    'Declare an object variable for the Reflection object
    Dim app As Attachmate_Reflection_Objects_Framework.ApplicationObject
   
    'Declare additional Reflection objects, such as frame, terminal, and view
    Dim frame As Attachmate_Reflection_Objects.frame
    Dim terminal As Attachmate_Reflection_Objects_Emulation_IbmHosts.IbmTerminal
    Dim view As Attachmate_Reflection_Objects.view

    Set app = New Attachmate_Reflection_Objects_Framework.ApplicationObject
 
    'wait until Reflection initializes
    Do While app.IsInitialized = False

    To run this sample

    1. In Reflection, create a new VT terminal session and in the Host Name /IP address box, enter "Demo:UNIX".
    2. Save the new session in your "My Documents\Micro Focus\Reflection" folder as GetData.rdox.
    3. On the Excel VBA Editor Tools menu, select References and then select the following Reflection Libraries:
    • Attachmate_Reflection_Objects
    • Attachmate_Reflection_Objects_Emulation_OpenSystems
    • Attachmate_Reflection_Objects_Framework
    1. Copy the following code into an Excel Sheet object code window and then run the GetDataFromReflection macro.

    Concepts

    First, the sample creates a Reflectionsession. The IBM sample does this by creating a new session and then assigning it the demo Host/IP address. The Open System sample opens an existing session. For details about concepts related to this part of the sample, see Create a Session From a Microsoft Excel Macro and Open a Session From a Microsoft Excel Macro.

    Then it navigates through the session to get to the screen data we want to copy.

    This sample uses the NewScreenReady event to navigate to the host screen that contains the data. Declaring a global IbmScreen object variable using the WithEvents keyword allows us to access the Reflection screen events from the Excel macro. 

    The ScreenID variables hold text from specific locations on each screen. The text in each variable is compared with known text to determine which screen the program is on and then keys are sent to navigate to the next screen until the program is on the screen with the INTERNATIONAL text. (This is the screen that has the data we need to copy to Excel.)

    Navigate to the screen that has the data
    Copy Code 
    Public WithEvents screen As Attachmate_Reflection_Objects_Emulation_IbmHosts.IbmScreen

Private Sub screen_NewScreenReady(ByVal sender As Variant)
    'In this IbmScreen
  
    Dim screenID1 As String, screenID2 As String, screenID3 As String
    Dim rCode As ReturnCode
    Dim rowText As String
    Dim rowFromHost() As String
    Dim col As Integer, row As Integer
  
    screenID1 = screen.GetText(1, 2, 6) 'ATM VM ispf
    screenID2 = screen.GetText(1, 7, 4) 'option 2
    screenID3 = screen.GetText(1, 25, 13) 'option 2
     
    If screenID1 = "ATM VM" Then
        rCode = screen.SendControlKey(ControlKeyCode_Transmit)
    End If
  
    If screenID2 = "ATM5" Then
        rCode = screen.PutText2("kayak", 23, 1)
        rCode = screen.SendControlKey(ControlKeyCode_Transmit)
    End If
  
    If screenID3 = "INTERNATIONAL" Then

...

    This sample enters commands to navigate to the screen that contains the data. After sending each command, it waits until the screen is ready before entering the next command.

    Navigate to the screen that has the data
    Copy Code 
        Set screen = terminal.screen
          
    screen.SendKeys "userID"
    screen.SendControlKey ControlKeyCode_Return
    rCode = screen.WaitForHostSettle(3000)
   
    screen.SendKeys "DemoPassWord"
    screen.SendControlKey ControlKeyCode_Return
    rCode = screen.WaitForHostSettle(3000)
 
    screen.SendKeys "demodata"
    screen.SendControlKey ControlKeyCode_Return
    rCode = screen.WaitForHostSettle(3000)

    When the program is on the screen with the data, the GetText method is used to get a row or data as a string. The Replace function is used to handle compound words and to remove unwanted characters and the Excel Trim function is used to remove all extra leading and trailing spaces and spaces between words. Then the string is converted to an array. 

    If you are copying structured data (as in our IBM sample), you can use the screen row coordinates for your starting point. For unstructured data (Open Systems), you'll need to get the starting point coordinates by recording a macro or by searching for unique text on the screen as shown in Navigating Sessions.

     

    Finally, the sample loops through the array and assigns the value of each element to a cell in the spreadsheet.

    This process is repeated until the macro encounters an empty row.
