How to configure and setup a generic emulator with SecureLogin

fix

SecureLogin provides a mechanism to interface with most any emulator. This would include HLLPI, DDE, VBA, etc... For those emulators that do not support a standard interface then SecureLogin can communicate via the Windows Clipboard to the application. Any application that has the ability to Copy and Paste from the Windows Clipboard can utilize the generic or advanced generic interface method.

Generic -vs- Advanced Generic

The only difference between the Generic and the Advanced Generic is the Select all option. If your application supports a select all option then use the generic interface. If it only supports copy and paste then use the advanced generic interface.

In our example we will be setting up Quick3270 to login to an AS400 host. If we look under the edit menu we see that we have Copy and Paste. We also have a Select All option that will perform a select all. For this example we will setup Quick3270 as a Generic emulator and use the select all, copy and paste functions. 

We must first create a dummy application that we will later modify to include our mainframe script. Right click on the SecureLogin icon in the system tray and select Manage Logins. Within the Manage Logins window click on the Applications tab. And finally click on the New button to create a new application.

Click on the New application radio button and then select the type "Terminal Launcher". Also provide a unique name for this application. In our example we will call this application "My Generic Emulator". Finally, click the Create button to create the application.

 

Click on the Script tab and enter a MessageBox command so that we can determine when our emulator launched. We will change this script later after we have successfully configured the Generic emulator. Click the OK button to complete this process.

Now we are ready to create the generic emulator definition. We do this from with the terminal launcher (tlaunch) utility. Click on the Start menu and browse to Programs/Novell SecureLogin/Terminal Launcher.

We must first create the emulator definition so click on the Edit Available Emulators button.

Terminal Launcher will provide a list of currently defined emulators. A large number of emulators are already defined in SecureLogin. You may scroll through the list to see if one is already defined for the emulator you are trying to configure. For our example we will be adding a new definition for Quick3270. Click on the New button to create a new emulator.

Select the Emulator type of Generic and give it a unique name. In our case we will call this "Quick3270 Generic".

We need to identify several items for a Generic emulator.

1. Emulator Path - This is the path to the program.

2. Host Name - This is an optional field to pass a host name or address to the application. This field may or may not work with all emulators since it is passed as a command line option.

3. Output ID's - This is the Windows control ID of the Copy function in the edit menu. (Covered below)

4. Input ID's - This is the Windows control ID of the Paste function in the edit menu. (Covered below)

5. Window Title - This is the Title of the Window as reported by the Window Finder tool. (Covered below)

6. Use Advanced Enter Method - This checkbox tells SecureLogin to send a \n instead of the default \r\n character sequences for an Enter key.

7. Emulator is 16 Bit - This checkbox tells SecureLogin to use older 16 bit interface with the emulator. When this option is selected then the WndClass option becomes active. Enter in the WndClass from the Window Finder tool.

So we first browse to the Quick3270 application by clicking the browse button to the very right of the Emulator Path field. If the path as in our example contains a long name with a space, then change the value to represent a short name. For example Program Files would be progra~1 instead. So we change our path to c:\progra~1\quick3270\quick3270.exe.

Now we need to find the Input and Output ID's of the emulators Copy and Paste functions. To do this we need to use a 3rd party tool called Winspector. If you have Microsoft's development tool SPY++ you can use it as well. Winspector is a free tool you can download from the Internet at http://www.windows-spy.com/.

Winspector will display all of the Windows system messages and is very configurable. We will need to configure Winspector so that it only displays the information we want to see. First download and install Winspector on your workstation.

With Winspector running launch your emulator. Within the Window List box of Winspector click on the Gun sight icon with the text "Click and drag to select a window" and drag it over the emulator title bar. Winspector will highlight the emulator box and display information about the emulator window in the upper left corner.

Now that the emulator has been selected we just need to trap for the messages being sent to the emulator window. Scroll down the Window list until you find the application, then right click on the application and select "Messages".

The messages window will now be displayed in the right pane. We now need to tell Winspector what messages we want to see.

Right click anywhere in the Messages window and select the option Edit message filter.

By default Winspector is not filter any messages. We want to filter all of the messages and then only display the one we want to see.

Click on the Filter all button.

Now we only want to see WM_COMMAND messages so we double click on the WM_COMMAND to move it to the unfiltered window on the right. Then we can click OK to return to the Messages window.

We only want to see the messages sent to the emulator window so right click on the Messages window and uncheck the option "Show return values".

Switch back to the emulator and open the edit menu option and select the Select All option.

Now if we look back in the messages window of Winspector we will see that the ID for the Select All option is 4104.

Perform the same steps to get the ID for the copy menu option. In the emulator select the edit menu and then the copy option.

The Copy function is ID 4102.

Perform the same steps for the Paste operation and we see that the Paste function is ID 4103.

Enter the ID's that we found into the emulator configuration of Terminal Launcher.

First enter the Select All and the Copy ID's into the Output ID's field separated by a comma.

Then enter the Paste ID into the Input ID's field.

Now we must find the Window Title. This is done with the Window Finder tool that is included with SecureLogin. Click on the Start menu and browse to Programs/Novell SecureLogin/Window Finder

Right click on the SecureLogin Icon in the Window Finder tool and drag it over the emulator title bar.

Copy the text from the Window Text field and paste it into our Terminal Launcher configuration.

 

Click the Ok button and we have completed the definition of our Generic emulator. Now all we should have to do is test our configuration. From the Terminal Launcher main window we select our application "My Generic Emulator" and then select the Emulator "Quick3270 Generic" and finally click the Launch button.

 

The emulator should be launched and we should see our message box indicating that our script ran.

We can also have the Terminal Launcher create an Icon on the desktop that will launch the emulator. From the Terminal Launcher main screen select the application and emulator as we did before, but instead of clicking on the Launch button, click on the Create Shortcut button. Then from the TLaunch Shortcut Options window click on the Create button.

A new icon should now appear on the desktop.

All that needs to be done now is to edit our script for this application. Right click on the SecureLogin icon in the system tray and select Manage Logins. Then scroll to the "My Generic Emulator" application from the Applications tab. Finally click edit.

Enter the host script as if you were typing directly into the emulator. For example if you must press the tab key twice before entering your user name then use SendKey "\T\T". Note that the SendKey function is available for Generic and Advanced Generic emulators. For other emulators just use the normal Type command. For more information on script commands refer to the scripting guide included with SecureLogin.

Note: You will see that the emulator screen will flash while it is performing the select all and copy functions looking for the sign on screen. This is normal since the emulator reverses the colors of the screen when text is marked for copy and paste. But this can be eliminated in one of two ways.

1. You can always configure the emulator to not invert the colors when data is copied and paste.

2. You can use the SecureLogin commands BeginSplashScreen and EndSplashScreen.

SecureLogin will now display the SecureLogin screen while we are waiting on the host screen to update. This way the flashing no longer occurs.
