content: Contents  Index  Topic Contents   Previous Topic: ShellExecute Next Topic: SHFileOperation    ShellExecuteEx   WINSHELLAPI BOOL WINAPI ShellExecuteEx(     LPSHELLEXECUTEINFO lpExecInfo );	  Performs an action on a file.   Returns a nonzero value if successful, or zero otherwise. To get extended error information, call theGetLastError function.  lpExecInfo  Address of a SHELLEXECUTEINFO structure that contains and receives information about the application being executed.  If the function succeeds, it sets the hInstApp member of the SHELLEXECUTEINFO structure to the instance handle to the application that the function started. If the function fails, hInstApp is one of the SE_ERR_ error values indicating the cause of the failure. (An instance handle will always be greater than 32 and an error value less than 32.) Note that the SE_ERR_ error values are for compatibility with the ShellExecute function; use theGetLastError function to retrieve error information.   The error value returned byGetLastError corresponds to the SE_ERR_ values and may be one of the following: ERROR_FILE_NOT_FOUND  The specified file was not found.  ERROR_PATH_NOT_FOUND  The specified path was not found.  ERROR_DDE_FAIL  The DDE transaction failed.  ERROR_NO_ASSOCIATION  There is no application associated with the given file name extension.  ERROR_ACCESS_DENIED  Access to the specified file is denied.  ERROR_DLL_NOT_FOUND  One of the library files necessary to run the application can't be found.  ERROR_CANCELLED  The function prompted the user for the location of the application, but the user canceled the request.  ERROR_NOT_ENOUGH_MEMORY  There is not enough memory to perform the specified action.  ERROR_SHARING_VIOLATION  A sharing violation occurred.     --------------------------------------------------------------------------------   Top of Page  © 1997 Microsoft Corporation.

Contents  Index  Topic Contents   Previous Topic: SHDESCRIPTIONID Next Topic: SHELLFLAGSTATE    SHELLEXECUTEINFO   typedef struct _SHELLEXECUTEINFO{     DWORD cbSize;      ULONG fMask;      HWND hwnd;      LPCTSTR lpVerb;      LPCTSTR lpFile;      LPCTSTR lpParameters;      LPCTSTR lpDirectory;      int nShow;      HINSTANCE hInstApp;        // Optional members      LPVOID lpIDList;      LPCSTR lpClass;      HKEY hkeyClass;      DWORD dwHotKey;      HANDLE hIcon;      HANDLE hProcess;  } SHELLEXECUTEINFO, FAR *LPSHELLEXECUTEINFO;     Contains information used by the ShellExecuteEx function.   cbSize  Size of the structure, in bytes.  fMask  Array of flags that indicate the content and validity of the other structure members. This can be a combination of the following values: SEE_MASK_CLASSKEY  Use the class key given by the hkeyClass member.   SEE_MASK_CLASSNAME  Use the class name given by the lpClass member.   SEE_MASK_CONNECTNETDRV  Validate the share and connect to a drive letter. The lpFile member is a Universal Naming Convention (UNC) path of a file on a network.   SEE_MASK_DOENVSUBST  Expand any environment variables specified in the string given by the lpDirectory or lpFile member.   SEE_MASK_FLAG_DDEWAIT  Wait for the DDE conversation to terminate before returning (if the ShellExecuteEx function causes a DDE conversation to start).  SEE_MASK_FLAG_NO_UI  Do not display an error message box if an error occurs.   SEE_MASK_HOTKEY  Use the hot key given by the dwHotKey member.  SEE_MASK_ICON  Use the icon given by the hIcon member.  SEE_MASK_IDLIST  Use the item identifier list given by the lpIDList member.   SEE_MASK_INVOKEIDLIST  Use the item identifier list given by the lpIDList member to invoke an application. If this member is NULL, the function creates an item identifier list and invokes the application. This flag overrides the SEE_MASK_IDLIST flag.  SEE_MASK_NOCLOSEPROCESS  Leave the process running after the ShellExecuteEx function exits. The hProcess member receives the handle to the process.    hwnd  Window handle to any message boxes that the system may produce while executing this function.  lpVerb  Address of a string specifying the name of a verb. The verb specifies an action for the application to perform. This member defaults to Open if no verb is specified.  lpFile  Address of a null-terminated string that specifies the name of the file to open or print. The function can open an executable file or a document file, but it can only print a document file. If the path is not included with the name, the current directory is assumed.  lpParameters  Address of a null-terminated string containing the application parameters. The parameters must be separated by spaces. To include double quotation marks, you must enclose the marks in double quotation marks, as in the following example:  sei.lpParameters = "An example: \"\"\"quoted text\"\"\"";  In this case, the application receives three parameters: An, example:, and "quoted text".   If the lpFile member specifies a document file, this member should be NULL.   lpDirectory  Address of a null-terminated string that specifies the name of the working directory. If this member is not specified, the current directory is used as the working directory.  nShow  Show flags. Can be one of the SW_ values described for theShowWindow function. If the lpFile specifies an executable file, this member specifies how the application is to be shown when it is opened.  hInstApp  Receives a value greater than 32 if successful, or an error value that is less than or equal to 32 otherwise. Error values can be one of the following: SE_ERR_FNF  File not found.  SE_ERR_PNF  Path not found.  SE_ERR_ACCESSDENIED  Access denied.  SE_ERR_OOM  Out of memory.  SE_ERR_DLLNOTFOUND  Dynamic-link library not found.  SE_ERR_SHARE  Cannot share an open file.  SE_ERR_ASSOCINCOMPLETE  File association information not complete.  SE_ERR_DDETIMEOUT  DDE operation timed out.  SE_ERR_DDEFAIL  DDE operation failed.  SE_ERR_DDEBUSY  DDE operation is busy.  SE_ERR_NOASSOC  File association not available.   lpIDList  Address of an ITEMIDLIST structure to contain an item identifier list uniquely identifying the file to execute. This member is ignored if the fMask member is not set to SEE_MASK_IDLIST.  lpClass  Address of a null-terminated string specifying the name of a file class or a globally unique identifier (GUID).This member is ignored if fMask is not set to SEE_MASK_CLASSNAME.  hkeyClass  Handle to the registry key for the file class. This member is ignored if fMask is not set to SEE_MASK_CLASSKEY.  dwHotKey  Hot key to associate with the application. The low-order word is the virtual key code, and the high-order word is a modifier flag (HOTKEYF_). For a list of modifier flags, see the description of theWM_SETHOTKEY message. This member is ignored if fMask is not set to SEE_MASK_HOTKEY.  hIcon  Handle to the icon for the file class. This member is ignored if fMask is not set to SEE_MASK_ICON.  hProcess  Handle to the newly started application. This member is set on return and is always NULL if fMask is not set to SEE_MASK_NOCLOSEPROCESS.   --------------------------------------------------------------------------------   Top of Page  © 1997 Microsoft Corporation.
