      • SHFileOperation

        int SHFileOperation​(ShellAPI.SHFILEOPSTRUCT fileop)
        This function can be used to copy, move, rename, or delete a file system object.
        Parameters:
        fileop - Address of an SHFILEOPSTRUCT structure that contains information this function needs to carry out the specified operation.
        Returns:
        Returns zero if successful, or nonzero otherwise.

      • SHGetFolderPath

        WinNT.HRESULT SHGetFolderPath​(WinDef.HWND hwndOwner,
                              int nFolder,
                              WinNT.HANDLE hToken,
                              WinDef.DWORD dwFlags,
                              char[] pszPath)
        Takes the CSIDL of a folder and returns the path.
        Parameters:
        hwndOwner - Handle to an owner window. This parameter is typically set to NULL. If it is not NULL, and a dial-up connection needs to be made to access the folder, a user interface (UI) prompt will appear in this window.
        nFolder - A CSIDL value that identifies the folder whose path is to be retrieved. Only real folders are valid. If a virtual folder is specified, this function will fail. You can force creation of a folder with SHGetFolderPath by combining the folder's CSIDL with CSIDL_FLAG_CREATE.
        hToken - An access token that can be used to represent a particular user.
        dwFlags - Flags to specify which path is to be returned.
        pszPath - Pointer to a null-terminated string of length MAX_PATH which will receive the path. If an error occurs or S_FALSE is returned, this string will be empty.
        Returns:
        Returns standard HRESULT codes.

      • SHGetKnownFolderPath

        WinNT.HRESULT SHGetKnownFolderPath​(Guid.GUID rfid,
                                   int dwFlags,
                                   WinNT.HANDLE hToken,
                                   PointerByReference ppszPath)
        Retrieves the full path of a known folder identified by the folder's KNOWNFOLDERID. This function replaces SHGetFolderPath(com.sun.jna.platform.win32.WinDef.HWND, int, com.sun.jna.platform.win32.WinNT.HANDLE, com.sun.jna.platform.win32.WinDef.DWORD, char[]). That older function is now simply a wrapper for SHGetKnownFolderPath.
        Parameters:
        rfid - A reference to the KNOWNFOLDERID (in KnownFolders) that identifies the folder.
        dwFlags - Flags that specify special retrieval options. This value can be 0; otherwise, one or more of the ShlObj.KNOWN_FOLDER_FLAG values.
        hToken - Type: HANDLE An access token that represents a particular user. If this parameter is NULL, which is the most common usage, the function requests the known folder for the current user. Request a specific user's folder by passing the hToken of that user. This is typically done in the context of a service that has sufficient privileges to retrieve the token of a given user. That token must be opened with TOKEN_QUERY and TOKEN_IMPERSONATE rights. In some cases, you also need to include TOKEN_DUPLICATE. In addition to passing the user's hToken, the registry hive of that specific user must be mounted. See Access Control for further discussion of access control issues. Assigning the hToken parameter a value of -1 indicates the Default User. This allows clients of SHGetKnownFolderPath to find folder locations (such as the Desktop folder) for the Default User. The Default User user profile is duplicated when any new user account is created, and includes special folders such as Documents and Desktop. Any items added to the Default User folder also appear in any new user account. Note that access to the Default User folders requires administrator privileges.
        ppszPath - When this method returns, contains the address of a pointer to a null-terminated Unicode string that specifies the path of the known folder. The calling process is responsible for freeing this resource once it is no longer needed by calling Ole32.CoTaskMemFree(com.sun.jna.Pointer). The returned path does not include a trailing backslash. For example, "C:\Users" is returned rather than "C:\Users\".
        Returns:
        Returns S_OK if successful, or an error value otherwise, including the following:
        • E_FAIL Among other things, this value can indicate that the rfid parameter references a KNOWNFOLDERID which does not have a path (such as a folder marked as KF_CATEGORY_VIRTUAL).
        • E_INVALIDARG Among other things, this value can indicate that the rfid parameter references a KNOWNFOLDERID that is not present on the system. Not all KNOWNFOLDERID values are present on all systems. Use IKnownFolderManager::GetFolderIds to retrieve the set of KNOWNFOLDERID values for the current system.

      • SHGetDesktopFolder

        WinNT.HRESULT SHGetDesktopFolder​(PointerByReference ppshf)
        Retrieves the IShellFolder interface for the desktop folder, which is the root of the Shell's namespace. The retrieved COM interface pointer can be used via Com4JNA's ComObject.wrapNativeInterface call given a suitable interface definition for IShellFolder
        Parameters:
        ppshf - A place to put the IShellFolder interface pointer
        Returns:
        If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

      • ShellExecute

        WinDef.INT_PTR ShellExecute​(WinDef.HWND hwnd,
                            String lpOperation,
                            String lpFile,
                            String lpParameters,
                            String lpDirectory,
                            int nShowCmd)
        Performs an operation on a specified file.
        Parameters:
        hwnd - A handle to the owner window used for displaying a UI or error messages. This value can be NULL if the operation is not associated with a window.
        lpOperation - A pointer to a null-terminated string, referred to in this case as a verb, that specifies the action to be performed. The set of available verbs depends on the particular file or folder. Generally, the actions available from an object's shortcut menu are available verbs. The following verbs are commonly used: edit Launches an editor and opens the document for editing. If lpFile is not a document file, the function will fail. explore Explores a folder specified by lpFile. find Initiates a search beginning in the directory specified by lpDirectory. open Opens the item specified by the lpFile parameter. The item can be a file or folder. print Prints the file specified by lpFile. If lpFile is not a document file, the function fails. NULL In systems prior to Windows 2000, the default verb is used if it is valid and available in the registry. If not, the "open" verb is used. In Windows 2000 and later, the default verb is used if available. If not, the "open" verb is used. If neither verb is available, the system uses the first verb listed in the registry.
        lpFile - A pointer to a null-terminated string that specifies the file or object on which to execute the specified verb. To specify a Shell namespace object, pass the fully qualified parse name. Note that not all verbs are supported on all objects. For example, not all document types support the "print" verb. If a relative path is used for the lpDirectory parameter do not use a relative path for lpFile.
        lpParameters - If lpFile specifies an executable file, this parameter is a pointer to a null-terminated string that specifies the parameters to be passed to the application. The format of this string is determined by the verb that is to be invoked. If lpFile specifies a document file, lpParameters should be NULL.
        lpDirectory - A pointer to a null-terminated string that specifies the default (working) directory for the action. If this value is NULL, the current working directory is used. If a relative path is provided at lpFile, do not use a relative path for lpDirectory.
        nShowCmd - The flags that specify how an application is to be displayed when it is opened. If lpFile specifies a document file, the flag is simply passed to the associated application. It is up to the application to decide how to handle it.
        Returns:
        If the function succeeds, it returns a value greater than 32. If the function fails, it returns an error value that indicates the cause of the failure. The return value is cast as an HINSTANCE for backward compatibility with 16-bit Windows applications. It is not a true HINSTANCE, however. It can be cast only to an int and compared to either 32 or the following error codes below. NOTE: WinDef.INT_PTR is used instead of HINSTANCE here, since the former fits the reutrn type's actual usage more closely. 0 The operating system is out of memory or resources. ERROR_FILE_NOT_FOUND The specified file was not found. ERROR_PATH_NOT_FOUND The specified path was not found. ERROR_BAD_FORMAT The .exe file is invalid (non-Win32 .exe or error in .exe image). SE_ERR_ACCESSDENIED The operating system denied access to the specified file. SE_ERR_ASSOCINCOMPLETE The file name association is incomplete or invalid. SE_ERR_DDEBUSY The DDE transaction could not be completed because other DDE transactions were being processed. SE_ERR_DDEFAIL The DDE transaction failed. SE_ERR_DDETIMEOUT The DDE transaction could not be completed because the request timed out. SE_ERR_DLLNOTFOUND The specified DLL was not found. SE_ERR_FNF The specified file was not found. SE_ERR_NOASSOC There is no application associated with the given file name extension. This error will also be returned if you attempt to print a file that is not printable. SE_ERR_OOM There was not enough memory to complete the operation. SE_ERR_PNF The specified path was not found. SE_ERR_SHARE A sharing violation occurred.

      • SHGetSpecialFolderPath

        boolean SHGetSpecialFolderPath​(WinDef.HWND owner,

      • SHAppBarMessage

        WinDef.UINT_PTR SHAppBarMessage​(WinDef.DWORD dwMessage,
                                ShellAPI.APPBARDATA pData)
        SHAppBarMessage function
        Parameters:
        dwMessage - Appbar message value to send. This parameter can be one of the following values. ShellAPI.ABM_NEW Registers a new appbar and specifies the message identifier that the system should use to send notification messages to the appbar.

ShellAPI.ABM_SETPOS Sets the size and screen position of an appbar. ShellAPI.ABM_GETSTATE Retrieves the autohide and always-on-top states of the Windows taskbar. ShellAPI.ABM_GETTASKBARPOS Retrieves the bounding rectangle of the Windows taskbar. Note that this applies only to the system taskbar. Other objects, particularly toolbars supplied with third-party software, also can be present. As a result, some of the screen area not covered by the Windows taskbar might not be visible to the user. To retrieve the area of the screen not covered by both the taskbar and other app bars -- the working area available to your application --, use the GetMonitorInfo function. ShellAPI.ABM_ACTIVATE Notifies the system to activate or deactivate an appbar. The lParam member of the APPBARDATA pointed to by pData is set to TRUE to activate or FALSE to deactivate. ShellAPI.ABM_GETAUTOHIDEBAR Retrieves the handle to the autohide appbar associated with a particular edge of the screen. ShellAPI.ABM_SETAUTOHIDEBAR Registers or unregisters an autohide appbar for an edge of the screen. ShellAPI.ABM_WINDOWPOSCHANGED Notifies the system when an appbar's position has changed. ShellAPI.ABM_SETSTATE Windows XP and later: Sets the state of the appbar's autohide and always-on-top attributes.
        pData - A pointer to an APPBARDATA structure. The content of the structure on entry and on exit depends on the value set in the dwMessage parameter. See the individual message pages for specifics.
        Returns:
        This function returns a message-dependent value. For more information, see the Windows SDK documentation for the specific appbar message sent.

        If this value is -1 and phiconLarge and phiconSmall are both NULL, the function returns the total number of icons in the specified file.
        If the file is an executable file or DLL, the return value is the number of RT_GROUP_ICON resources.
        If the file is an .ico file, the return value is 1. If this value is a negative number and either phiconLarge or phiconSmall is not NULL, the function begins by extracting the icon whose resource identifier is equal to the absolute value of nIconIndex. For example, use -3 to extract the icon whose resource identifier is 3.
        phiconLarge - Type: HICON*
        An array of icon handles that receives handles to the large icons extracted from the file. If this parameter is NULL, no large icons are extracted from the file.
        phiconSmall - Type: HICON*
        An array of icon handles that receives handles to the small icons extracted from the file. If this parameter is NULL, no small icons are extracted from the file.
        nIcons - Type: UINT
        The number of icons to be extracted from the file.
        Returns:
        Type: UINT
        If the nIconIndex parameter is -1, the phiconLarge parameter is NULL, and the phiconSmall parameter is NULL, then the return value is the number of icons contained in the specified file. Otherwise, the return value is the number of icons successfully extracted from the file.
