Slide 5

Smart Card InTouch utilizes the following smart card related APIs exposed by Microsoft. Note: The AppServer xxSecurity also utilizes these APIs to support smart card authentication for the Galaxy OS authentication using smart card. Windows Smart Card APIs will be used to detect the presence of the smart card in the system. Refer to the following link for details: http://go.microsoft.com/fwlink/?LinkId=93347 Microsoft Cryptographic services will be leveraged to read certificates that are stored in the smart card. Refer to following link for details:

Smart Card Hardware

• C2-40 Mini Driver Smart Card

• OK 3021 USB Smart Card Readers

Slide 7

Show/Hide Graphics

•

The Show/Hide Graphic script functions allow you to write ArchestrA Graphics scripts to display a symbol as a pop-up window and close the pop-up window.

•

The HideGraphic script function allows you to close any ArchestrA symbol, displayed through the ShowGraphic script function.

•

The HideSelf script function allows you to close the symbol, displayed by either the ShowGraphic script function or the ShowSymbol animation.

Slide 8

Show Graphic Function Structure

Dim graphicInfo as aaGraphic.GraphicInfo; graphicInfo.Identity = ""; graphicInfo.GraphicName = "";

ShowGraphic( graphicInfo );

Slide 9

Show/Hide Graphic Script Tips and Examples The Show/Hide Graphic script functions allow for a wide range of

scripted uses: • Using Predefined and Named Scripts • Working with Modal Windows • Using Hierarchical References and Containment Relationships • Scripting the Owning Object • Scripting Multiple Symbols

Slide 10

Important Note on ShowGraphic Function

•

The ShowGraphic function can be used in a symbol’s action script, named script and pre-defined script. Although the system allows you to include it in a server script, such as Start Up, On Scan, OffScan, Shut Down and Execute, you will not be able to execute the function at run time.

•

Detailed Examples are on Tech Note 815

Slide 11

Tag Viewer •

You can start Tag Viewer only if WindowViewer is running, and Tag Viewer has been enabled at design time.

•

You can launch Tag Viewer from the WindowViewer menu or from a script calling the LaunchTagViewer() function.

•

The above function can be executed from any script type, except application scripts: OnStartup and OnShutdown.

•

If Tag Viewer is not enabled, calling the function will not start Tag Viewer and a warning message will be logged in the logger.

•

You must have adequate security privileges to run Tag Viewer

Memory Caching for WindowViewer Windows

•

You can configure how WindowViewer uses memory for Windows to improve performance at run time.

•

Windows can be kept in memory at run time in certain conditions to allow for fast retrieval.

•

You can also specify the interval for a periodic memory health check and settings for the heap memory segment.

Slide 17

Viewer Memory Caching •

In-Memory Window Caching • Memory Limit for In-Memory Windows

• The default memory limit is 70% of process memory. • In-Memory Window Expiration Time • The default value is 0 hours, which designates no time limit. • You can enter a value between 0 and 8760 hours (365 days)

•

High Priority Window Caching •

Enable High Priority Window Caching This allows some windows to be marked as high priority.

• Memory Limit for High Priority Windows

• The default memory limit is 90%.

Slide 21

Expose Window Name Property •

GetWindowName script function enables the user to retrieve the name of the window under which the function has been called.

•

The syntax of the script function is as follows: Resultcode = GetWindowName(tagname);

•

Resultcode indicates the success or failure of the script function. The resultcode can be a Discrete/Integer/Real data type.

•

Resultcode will be 1 or 0, based on the success or failure of the script function: • Resultcode is 1 when the script function is called from window context. • Resultcode is 0 when the script function is called from non-window context.

Slide 40

Issue 4: Event Viewer for View Crash and Hang

Slide 41

Issue 4: View Crash Causes / Solutions Cause #1: WWHeap conflict or Out of Memory. Look for WWHeap messages in Log Viewer or Event Viewer

Solution #1: Increase WWHeap Memory (Tech Note 768) or in Node Properties for InTouch 10.5 Cause #2: Not having the latest InTouch Service Pack and patch installed. Cause #3: Running View on a non-supported OS / Service Pack. Solution #3: Check the InTouch Readme for supported OS Cause #4: View out of memory Solution #4: Verify with Performance Monitor. Isolate to individual windows or window combinations

Slide 42

Issue 4: View Crash Causes / Solutions Cause #5: Scripting. Application While Running script causing resource issue or an individual script causing a crash. Solution #5: Isolate down to individual script. Print scripts to file for analysis. Cause #6: View caused an invalid page fault in module CBTREENT.dll. Solution #6: Corrupt InTouch History Files. Isolate to individual day causing the problem. Cause #7: Corrupt window or InTouch App Solution #7: Recompile the app OR rebuild the app (Tech Note 570 for Managed Apps, Tech Note 774 for Standalone apps)

Use Crash Dump if still unresolved
