    Enter Data Using an Excel Form
    In This Topic

    This sample shows how to use an Excel form to enter data into a terminal screen. When the login button is clicked, the macro creates a session, enters the User name and Password into the program, and then navigates to the screen that has the data form. When the Enter Data button is pressed, the macro checks to make sure the user has logged in and displays a message to log in if required. If the user has logged in, the macro enters the data from the user form into the program.   


    This sample applies only to IBM terminals

    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. Create a User Form with the following controls:
      Properties Names
      Text Boxes
      List Box lstGroup
      Check Box optType
      Command Buttons cmdEnterData, cmdLogin
    2. Copy the following code into the form code window and then place the cursor in UserForm_Initialize and press F5 to initialize the form.
      Enter data from an Excel user form
      Copy Code
      Dim screen As Attachmate_Reflection_Objects_Emulation_IbmHosts.ibmScreen
      Private Sub UserForm_Initialize()
          'Empty ProjectTextBox
          txtUserName.Value = ""
          'Empty TypeRadioButtons
          txtPassword.Value = ""
          'Empty ProjectTextBox
          txtProject.Value = ""
          'Empty MemberTextBox
          txtMember.Value = ""
          'Empty GroupListBox
          With lstGroup
              .AddItem "Acct"
              .AddItem "Eng"
              .AddItem "Mktng"
          End With
          lstGroup.Value = "Acct"
          optType.Value = "True"
      End Sub
      Private Sub cmdLogin_Click()
          '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
          Dim path As String
          Dim rCode As ReturnCode
          'Assign the Application object to the object variable. The following code creates an instance of Reflection:
          Set app = New Attachmate_Reflection_Objects_Framework.ApplicationObject
          'wait until Reflection initializes
          Do While app.IsInitialized = False
              app.Wait 200
          'Create controls to open and display the session document.
          Set frame = app.GetObject("Frame")
          Set terminal = app.CreateControl2("09E5A1B4-0BA6-4546-A27D-FE4762B7ACE1")
          terminal.HostAddress = "demo:ibm3270.sim"
          Set view = frame.CreateView(terminal)
          frame.Visible = True
          Set screen = terminal.screen
          'Enter the password data from the form
          rCode = screen.PutText2(txtUserName.Value, 20, 16)
          rCode = screen.PutText2(txtPassword.Value, 21, 16)
          'navigate to the screen you want to screen scrape
          rCode = screen.SendControlKey(ControlKeyCode_Transmit)
          rCode = screen.WaitForHostSettle(3000, 2000)
          rCode = screen.SendKeys("ISPF")
          rCode = screen.SendControlKey(ControlKeyCode_Transmit)
          rCode = screen.SendKeys("1")
          rCode = screen.SendControlKey(ControlKeyCode_Transmit)
          'Clear the form data
      End Sub
      Private Sub cmdEnterData_Click()
          Dim project, projectType, group, member  As String
          Dim rCode As ReturnCode
          Dim app As Attachmate_Reflection_Objects_Framework.ApplicationObject
          'If Reflection isn't open, exit and display a message to log in.
          On Error GoTo ErrorHandler
          Set app = GetObject("Reflection Workspace")
          project = txtProject.Value
          group = lstGroup.Value
          member = txtMember.Value
          If optType.Value = "True" Then
              projectType = "New"
              projectType = "Funded"
          End If
          'Put the text for each value into the appropriate field
          rCode = screen.PutText2(project, 5, 18)
          rCode = screen.PutText2(group, 6, 18)
          rCode = screen.PutText2(projectType, 7, 18)
          rCode = screen.PutText2(member, 8, 18)
          'put in the command to enter the data and go to the next screen
          rCode = screen.PutText2("autoexec", 2, 15)
          rCode = screen.SendControlKey(ControlKeyCode_Transmit)
          rCode = screen.WaitForHostSettle(3000, 2000)
          rCode = screen.SendControlKey(ControlKeyCode_F3)
          rCode = screen.WaitForHostSettle(3000, 2000)
          'Clear the form data
          'Exit to avoid running the error handler when there is no error
          Exit Sub
              MsgBox "You need to log in"
          Exit Sub
      End Sub
    3. Log in using any credentials, wait for Reflection to open, and enter some data.


    The UserForm_Initialize() Sub creates the form displayed at the top of this article. When the Login button is clicked, the LoginButton_Click() creates a new Reflection session as explained in Create a Session From a Microsoft Excel Macro. Then it enters the user name and password from the form into the appropriate fields on the first screen, using the ibmScreen.PutText2 method. Finally, it navigates to the screen that has the data form as explained in Navigating Sessions.

    For IBM sessions, another approach for screen navigation is to handle the NewScreenReady event for the new session. If you use this approach, you'll need to set up your macro for this event as shown in Using Reflection Events in Sessions Created at Runtime

    When the Enter Data button is clicked, the EnterDataButton_Click() Sub checks to make sure the user has logged in. Then it assigns the form field values to local variables and uses the PutText2 method to put the text from each form field into the appropriate program field. After the data is entered using the SendControlKey method, the user form is initialized again.
