Handheld Device Troubleshooting and ActionScript Quiz

The escape() function in ActionScript converts a parameter to a string and encodes it in URL-encoded format. All non-alphanumeric characters (except some like * @ - _ . +) are replaced with %XX hexadecimal sequences. For example, a space becomes %20. This is essential for passing data safely in URLs.

The getTimer() function in ActionScript returns the number of milliseconds that have elapsed since the SWF (Shockwave Flash) file started playing. This is commonly used for animation timing, performance measurement, and creating time-based behaviors. The return value is in milliseconds, not seconds or minutes.

The getVersion() function in ActionScript returns a string containing Flash Player version and platform information. This includes details like the operating system (WIN, MAC, UNIX) and the Flash Player version number. There is no function named getFlashVersion() or getLatestVersion() in standard ActionScript.

MMExecute() is the specific ActionScript function that allows executing Flash JavaScript API (JSAPI) commands from within ActionScript. This enables communication between ActionScript and the Flash authoring environment or Flash Player. The other functions listed (_execute() and the options) are not standard ActionScript/Flash JSAPI functions.

fscommand() is the ActionScript function that enables communication between a SWF file and its host environment (Flash Player or web browser). It can send commands to JavaScript, control fullscreen mode, prevent scaling, and execute other host-specific operations. The other options (flcommand, command, fcommand) are not valid ActionScript functions.

onClipEvent() is the correct ActionScript handler for events specific to movie clip instances, such as load, enterFrame, mouseDown, etc. It's placed directly on the movie clip instance. The other options (onEvent, clipEvent, movieClipEvent) are not valid ActionScript event handlers.

parseFloat() is the standard JavaScript/ActionScript function that parses a string and converts it to a floating-point number. It extracts the first valid number from the beginning of the string. The other options (toFloat, float, stringToFloat) are not standard functions in JavaScript or ActionScript.

isFinite() is the standard JavaScript/ActionScript function that checks if a value is a finite number (not infinity or NaN). It returns true for finite numbers and false for infinity, -infinity, or NaN. The other options (isItFinite, _finite, _isFinite) are not valid function names.

eval() is a JavaScript/ActionScript function that evaluates a string expression and can access variables, properties, objects, or movie clips by name. It dynamically executes code stored as strings. The other options (toEval, toStr, string) are not valid functions for this purpose.

The 'net start' command is used to start a Windows service. 'net stop' stops a service. Option B correctly shows the command to start the handheld server service. Options C and D have incorrect service names that don't match the standard service naming convention.

The .sdf (SQL Database File) extension is used for storing structured data, including stock information in handheld systems. Other extensions like .fdf, .sds, or no extension are not standard database file formats used for this purpose in the context.

When performing a cold reset on handheld devices, the standard procedure involves warm resets with specific timing intervals. The 3:2:2 notation likely represents the timing sequence between warm reset attempts during the cold reset process. This is a device-specific operational procedure.

When a touchscreen is not working, the standard troubleshooting approach is to try a warm reset first. If that doesn't work, proceed to a cold reset. Option D includes both methods, which is the comprehensive approach to resolving touchscreen issues. Neither method alone is guaranteed to work.

Razdial error (a connection/network error) is typically resolved with a warm reboot, which refreshes the network stack and clears temporary errors. Killing data transfer or cold reset are more drastic measures not needed as immediate fixes. A warm reboot is the standard first response to such errors.

Cradle Manager is the application used to check network connectivity for handheld stock controllers. It monitors the connection between the handheld device and its cradle. 'Symbol' is a device manufacturer, 'Pinging' is a network utility, and 'stcock management' appears to be a typo for 'stock management' which is not the connectivity tool.

TTL (Time To Live) of 57 in a ping response indicates the network distance. Default TTL is often 64 for Windows systems. A value of 57 means the packet has passed through 7 network hops (64 - 57 = 7) to reach the destination. This is a normal network response.

There are typically two ways to restart the HHS (Handheld Service): via command line using 'net start/stop' commands and through the Windows Services GUI interface. These are the standard methods for service management in Windows environments.

Standard network ports on devices typically have two indicator lights: one for link status (showing physical connection) and one for activity (showing data transmission). This is the standard design for network ports including those on HHS devices.

In DataStage transformer stages, nulls in input columns used in derivations (A), constraints (B), or stage variable derivations (C) cause row rejection. Direct column mapping (D) preserves nulls without rejection. This prevents null propagation errors in downstream expressions.
