Grammar

WshShell.SpecialFolders.Item ("strFolderName") = strFolderPath

WshShell.SpecialFolders ("strFolderName") = strFolderPath

Annotation

If the requested folder (strFolderName) is not available, WshShell.SpecialFolders ("strFolderName") returns NULL. For example, Windows 95 does not have an AllUsersDesktop folder, and if strFolderName = AllUsersDesktop, it returns NULL.

The following specified folders are available for Windows 95 and Windows NT 4.0 operating systems:

WshShell.CreateShortcut

The CreateShortcut method creates a WshShortcut object and returns it. If the shortcut title ends with .url, a WshURLShortcut object is created.

Grammar

WshShell.CreateShortcut (strPathname) = objShortcut

Example

'This code fragment creates a shortcut

'to the currently executing script

Set WshShell = Wscript.CreateObject ("Wscript.Shell")

Set oShellLink = WshShell.CreateShortcut ("Current Script.lnk")

OShellLink.TargetPath = Wscript.ScriptFullName

OShellLink.Save

Set oUrlLink = WshShell.CreateShortcut ("Microsoft Web Site.URL")

OUrlLink.TargetPath = "http://www.microsoft.com"

OUrlLink.Save

Please refer to

WshShortcut object, WshUrlShortcut object

WshShortcut object

The object is not given directly. To get the WshShortcut object, use the WshShell.CreateShortcut method.

ProgID N/A

File name WSHom.Ocx

CLSID F935DC28-1CF0-11d0-ADB9-00C04FD58A0B

Grammar

WshShortcut.Description = strDescription

WshShortcut.Hotkey

The HotKey property provides hotkeys for shortcut objects. Hotkeys are keyboard shortcuts to start or switch programs.

Grammar

WshShortcut.HotKey = strHotKey

Annotation

The BNF syntax for strHotKey is as follows:

Hotkey:: = modifier* keyname

Modifier:: = "ALT+" | "CTRL+" | "SHIFT+" | "EXT+"

Keyname:: = "A".. "Z" |

"0".. "9" |

"Back" | "Tab" | "Clear" | "Return" |

"Escape" | "Space" | "Prior" |.

The names of all keys can be found in WINUSER.H. Hotkeys are not case sensitive.

Hotkeys can only activate shortcuts located on the Windows desktop or on the Windows start menu.

Windows Explorer does not accept ESC, ENTER, TAB, SPACE, PRINT SCREEN, or BACKSPACE, even if WshShortcut.Hotkey complies with Win32 API and supports them. Therefore, it is recommended that you do not use these keys in shortcuts.

Example

Set WshShell = Wscript.CreateObject ("Wscript.WshShell")

StrDesktop = WshShell.SpecialFolders ("Desktop")

Set oMyShortcut = WshShell.CreateShortcut (strDesktop & "\ a_key.lnk")

OMyShortcut.TargetPath = "% windir%\ notepad.exe"

OMyShortCut.Hotkey = "ALT+CTRL+F"

The ExpandEnvironmentStrings method extends the PROCESS environment variable in strString and returns the result string. Variables are enclosed by the'% 'character.

Environment variables are not case sensitive.

Grammar

WshShell.ExpandEnvironmentStrings (strString) = strExpandedString

Example

MsgBox "Prompt is" & WshShell.ExpandEnviromentStrings ("% PROMPT%")

WshShell.Popup

The Popup method displays a pop-up message box window containing messages specified by strText. The window title of the message box is specified by strTitle. If strTitle is omitted, the window title is Windows Scripting Host.

Grammar

WshShell.Popup (strText, [natSecondsToWait], [strTitle], [natType]) = intButton

Annotation

If natSecondsToWait is provided and its value is greater than zero, the message box closes after natSecondsToWait seconds.

The meaning of natType is not the same as that in Win32? The same as in the MessageBox function. The following table shows the values and meanings in natType. The values in the following table can be combined.

Button Typ

Value description

0 displays the OK button

1 display the OK and cancel buttons

The return value intButton indicates the button number that the user clicked. If the user does not click the button before natSecondsToWait seconds, the intButton is set to-1.

Value description

1 "OK" button

2 cancel button

3 "stop" button

4 "retry" button

5 ignore button

6 "Yes" button

The strName parameter must start with the following root key name.

Short Long

HKCU HKEY_CURRENT_USER

HKLM HKEY_LOCAL_MACHINE

HKCR HKEY_CLASSES_ROOT

HKEY_USERS

HKEY_CURRENT_CONFIG

Annotation

The RegRead method supports only REG_SZ, REG_EXPAND_SZ, REG_DWORD, REG_BINARY, and REG_MULTI_SZ data types. RegRead returns DISP_E_TYPEMISMATCH if there are other data types in the registry.

Example

Set WshShell = Wscript.CreateObject ("Wscript.Shell")

WshShell.RegRead ("HKCU\ ScriptEngine\ Val") 'Read from value "Val"

WshShell.RegRead ("HKCU\ ScriptEngine\ Key\") 'Read from key "Key"

Please refer to

AnyValue

When strType is REG_SZ or REG_EXPAND_SZ, the RegWrite method automatically converts anyValue to a string. If strType is REG_DWORD, anyValue is converted to an integer. If strType is REG_BINARY, anyValue must be an integer.

StrType

The RegWrite method supports strType of REG_SZ, REG_EXPAND_SZ, REG_DWORD, and REG_BINARY. If other data types are passed as strType, RegWrite returns E_INVALIDARG.

Example

Set WshShell = Wscript.CreateObject ("Wscript.Shell")

WshShell.RegWrite "HKCU\ ScriptEngine\ Value", "Some string value"

WshShell.RegWrite "HKCU\ ScriptEngine\ Key\", 1 "REG_DWORD"

Please refer to

WshShell.RegDelete method, WshShell.RegWrite method

WshShell.Run

The Run method creates a new process that executes strCommand in the style of an intWindowStyle window.

Grammar

WshShell.Run (strCommand, [intWindowStyle], [blnWaitOnReturn])

Parameters.

StrCommand

The environment variables inside the strCommand parameter are automatically extended.

IntWindowStyle

This is the value of the wShowWindow element set within the STARTUPINFO structure for the new process. It has the same meaning as the nCmdShow parameter in ShowWindow, and can take one of the following values. Name value meaning

SW_HIDE

0 hide the window and activate another window.

SW_MINIMIZE

6 minimize the specified window and activate the next top-level window sorted in Z order.

SW_RESTORE

SW_SHOW

5 activate and display the window at the current size and position.

SW_SHOWMAXIMIZED

3 activate the window and maximize the window.

SW_SHOWMINIMIZED

SW_SHOWNOACTIVATE

4 display by the nearest size and position of the window. The active window remains active.

SW_SHOWNORMAL

1 activate and display a window. If the window is minimized or maximized, it is restored to its original size and position.

BlnWaitOnReturn

If blnWaitOnReturn is not specified or its value is FALSE, the method immediately returns to the script to continue execution without waiting for the process to end.

If blnWaitOnReturn is set to TRUE, the Run method returns any error code returned by the application. If blnWaitOnReturn is not specified or its value is FALSE, Run returns error code 0 (zero).

Example

'This fragment launches Notepad with the current executed script

Set WshShell = Wscript.CreateObject ("Wscript.Shell")

WshShell.Run ("notepad" & Wscript.ScriptFullName)

WshShell.Run ("% windir%\ notepad" & Wscript.ScriptFullName)
