SendKey for Enter from vbscript to Attachmate

[RitaG]

Hi,

I have a requirement, which requires connecting to Attachmate using VBScripts. My problem is fairly basic. I have tried a LOT of things, but I just can't get the SendKeys operation for Enter to work.

I have tried :

' gobjTerminal is the Terminal object for the current session
' Set gobjScreen = gobjTerminal.Screen

1. gobjScreen.SendKeys ("<Enter>")
2. gobjScreen.SendControlKeys_Transmit
3. gobjScreen.TransmitTerminalKey ([ENTER])
4. gobjScreen.TransmitTerminalKey (289)
5. Set WshShell = CreateObject("WScript.Shell")
WshShell.SendKeys "{ENTER}"
6. gobjScreen.SendKeys "{ENTER}"

None seem to work. I am fairly new to Attachmate, right now I'm completely lost. Any assistance would be highly appreciated !!

PS :- A doubt :
in many posts I have seen the following line
Sess0.Screen.SendKeys ("<ENTER>")

What is Sess0 ? And what is its definition ?

 

[RitaG]

I'm sorry ...

its actually :
2. gobjScreen.SendControlKeys ControlKeyCode_Transmit

 

[RitaG]

Any help please ?? Really desperate... Cannot do any sendkey function like F11 or F8 either....

hi,

Attachmate Extra has no terminal object!

To get you started...

    Set oSystem = CreateObject("Extra.System")
'[highlight]this happens to be where my emulator is stored[/highlight]   
    Set oSess = oSystem.Sessions.Open("C:\Program Files\E!PC\Sessions\Mainframe.edp")

    With oSess
        .Visible = True
        .WindowState = xNORMAL
    End With

    Set oScrn = oSess.SCREEN

    oScrn.SendKeys ("<ENTER>")

I am using Attachmate Reflection Suite 4x 2011, running the script in QTP. I really new to this so I'm really sure if this is different from Attachmate Extra.

This is how I am creating the object:
Set gobjApplication = CreateObject("Attachmate_Reflection_Objects_Framework.ApplicationObject")

.Sessions.Open throws an error saying the code is not supported.

 

[SkipVought]

Use your HELP feature to find the available objects and methods.

The HELP ain't very helpful :/

These are members of IBMScreen objects (From Attachmate HELP):
.SendControlKeySync ControlKeyCode_Transmit
.SendControlKeys ControlKeyCode_Transmit

But these dont work either. Nothing happens on the screen. No error is thrown either.

 

[SkipVought]

Can't help you with Reflection.

I'd only say, start with the application object and work down.

Hi,

I wrote this a few years ago to automate working with Extra

Its basically a wrapper Class Module which you can add to your Project,

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
To use it just add a line like to your code dont forget to add a reference to Extra!

Private WithEvents Tool As clsExtra ' declare (Tool is just a name)

then just say something like Tool. and it will list the methods in the class, or you can add your own methods

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

Here's the Code for the class, just add a class to your project and paste this into it. Worked for me for years...

Hi,,

oops!!

I missed off one really important bit, in your startup form or Sub Main() you'll need to instantiate the class like below

Tool = New clsExtra

then you can use the intellisense Tool. and it should drop you a list of the methods in the class.

This was written for an IBM Host Session, I've got a couple of bits and peices for a Unix Host if you need any more.

Hey Steve,

As mentioned earlier, I am using Attachmate Reflection Suite 4x 2011. Is this the same as the version you are talking about ?
Instead of a Session object, an Application object gets created.. so I really dont know how to go forward with that.

 

[SkipVought]

BTW, using a WAIT method for a specified time, is like saying, "When I get to the traffic light, I'll wait for 10 seconds, then I'll go!" Sometimes you'll be waiting TOO long. Sometimes you'll not be waiting long enough (and loose data)!!!
[tt]
1. use MoveRelative to move the cursor away from the screen's Cursor rest Postion.

2. Issue the Control Key String using SendKeys

3. Loop until the cursor appears at the screen's Cursor rest Postion.
[/tt]

   With oScreen
        .MoveRelative 1, 1, 1
        .SendKeys ("<enter>")
        Do Until .WaitForCursor(3, 19)
            DoEvents
        Loop
   End With

Thanks a lot, Steve and Skip.

And I agree about the "WAIT". I was wondering how to go around that, so thanks again Skip
