SystemUtil Object
Description
An object used to control applications and processes during a run session.
IMPORTANT
The SystemUtil object is a UFT One reserved object. Reserved objects are not learned or stored in the object repository. Reserved objects enable you to retrieve or control UFT One settings or to modify UFT One behavior during a run session. Most UFT One reserved objects are described in the Utility section of the Object Model Reference.
Operations
The sections below list the built-in methods and properties that you can use as operations for the SystemUtil object.
Methods

BlockInput Method
Description
Prevents keyboard and mouse input events from reaching applications.
Syntax
object.BlockInput
Return Type
None
IMPORTANT
You can use this method to prevent a run session being accidentally interrupted by someone using the keyboard or mouse on a UFT One computer.
After using this method, keyboard and mouse input is blocked until one of the following occurs:
- An UnblockInput statement is used
- A run session ends or is paused for any reason (end of test run, run error, breakpoint)
- The Ctrl+Alt+Delete key combination is pressed on the keyboard
- A critical system error occurs
Example
'The following example uses the BlockInput method to block keyboard 'and mouse input to the UFT One computer during the run session. SystemUtil.BlockInput Browser("Welcome: Booking Site").Page("Welcome: Booking Site").WebEdit("userName").Set "Company" Browser("Welcome: Booking Site").Page("Welcome: Booking Site").WebEdit("password").SetSecure "4082986e39ea469e70dbf8c5a29429fe138c6efc" Browser("Welcome: Booking Site").Page("Welcome: Booking Site").Image("Sign-In").Click 2, 2 SystemUtil.UnblockInput
CloseDescendentProcesses Method
Description
Closes all processes opened by UFT One.
Syntax
object.CloseDescendentProcesses
Return Type
A long integer value.
The number of instances of the application that are closed when the statement runs.
IMPORTANT
Note: UFT One initially tries to close the process by sending a WM_CLOSE message to the process window. If the process is still open after 5 seconds, UFT One terminates the process.Example
'Suppose that the Record and Run dialog box opens a Windows Explorer window 'at the beginning of a test run, and then the statement below opens a 'Notepad window. In this case the message box statement below displays 2. SystemUtil.Run "Notepad.exe" MsgBox SystemUtil.CloseDescendentProcesses
CloseProcessByHwnd Method
Description
Closes a process that is the owner of a window with the specified handle.
Syntax
object.CloseProcessByHwnd (hWnd)
Arguments
Parameter | Description |
---|---|
hWnd |
Required. An unsigned long integer value.
The handle of the window owned by the process you want to close. Tip: You can retrieve the window handle using the hwnd property. For example: Window("MyAppName").GetROProperty("hwnd") |
Return Type
A Boolean value.
- True--The specified process was successfully closed.
- False--The specified process was not closed.
IMPORTANT
Note: UFT One initially tries to close the process by sending a WM_CLOSE message to the process window. If the process is still open after 5 seconds, UFT One terminates the process.Example
'The following example retrieves the handle of the Notepad window, and then 'uses the CloseProcessByHwnd method to close the notepad application. hWnd = Window("Notepad").GetROProperty("hwnd") SystemUtil.CloseProcessByHwnd (hWnd)
CloseProcessById Method
Description
Closes a process according to its Process ID (PID).
Syntax
object.CloseProcessById (wdProcessId)
Arguments
Parameter | Description |
---|---|
wdProcessId |
Required. An unsigned long integer value.
The Process ID (PID) of the process you want to close. Tip: You can find the PID of an application by viewing the value in the Processes tab of the Windows Task Manager, or you can retrieve the value using the process id property. For example: Window("MyAppName").GetROProperty("process id") |
Return Type
A Boolean value.
- True--The specified process was successfully closed.
- False--The specified process was not closed.
IMPORTANT
Note: UFT One initially tries to close the process by sending a WM_CLOSE message to the process window. If the process is still open after 5 seconds, UFT One terminates the process.Example
'The following example retrieves the process ID of the Notepad window, and then 'uses the CloseProcessByID method to close the notepad application. PID = Window("Notepad").GetROProperty("process id") SystemUtil.CloseProcessById (PID)
CloseProcessByName Method
Description
Closes a process according to its name.
Syntax
object.CloseProcessByName (bsProcessName)
Arguments
Parameter | Description |
---|---|
bsProcessName |
Required. A String value.
The name of the process you want to close.
|
Return Type
A long integer value.
The number of instances of the application that are closed when the statement runs.
IMPORTANT
Note: UFT One initially tries to close the process by sending a WM_CLOSE message to the process window. If the process is still open after 5 seconds, UFT One terminates the process.Example
'The following example uses the CloseProcessByName method to close any open 'instances of Notepad. If the only instances of Notepad that are open are ' those opened by the statements below, then the MsgBox displays 3. SystemUtil.Run "Notepad.exe" SystemUtil.Run "Notepad.exe" SystemUtil.Run "Notepad.exe" MsgBox SystemUtil.CloseProcessByName("Notepad.exe")
CloseProcessByWndTitle Method
Description
Closes all processes that are owners of windows with the specified title.
Syntax
object.CloseProcessByWndTitle (bsTitle, [bRegExp])

Indicates whether the bsTitle argument is treated as a regular expression.
Default value = False |
Return Type
A long integer value.
The number of instances of the application that are closed when the statement runs.
IMPORTANT
Note: UFT One initially tries to close the process by sending a WM_CLOSE message to the process window. If the process is still open after 5 seconds, UFT One terminates the process.Example
'The following example closes all top-level windows with a titlebar that contains the 'string "Notepad", by specifying "Notepad" as a regular expression. SystemUtil.CloseProcessByWndTitle "Notepad", True

Tip: You can also use this method to perform operations on the specified file, similar to the usage of the Windows ShellExecute command.
Example
'The following example uses the Run method to open a file named type.txt 'in the default text application (Notepad). It then types "happy days", 'saves the file using shortcut keys, and then closes the application. SystemUtil.Run "C:\type.txt", "", "", "" Window("Text:=type.txt - Notepad").Type "happy days" Window("Text:=type.txt - Notepad").Type micAltDwn & "F" & micAltUp Window("Text:=type.txt - Notepad").Type micLShiftDwn & "S" & micLShiftUp Window("Text:=type.txt - Notepad").Close
