SHELLEXECUTEINFO

Specifies an enumerated type that defines flags used with the IShellFolder::EnumObjects method.

The SHELLEXECUTEINFO structure contains information used by the ShellExecuteEx function.

typedef struct _SHELLEXECUTEINFO { // sei

DWORD cbSize;

ULONG fMask;

HWND hwnd;

LPCSTR lpVerb;

LPCSTR lpFile;

LPCSTR lpParameters;

LPCSTR lpDirectory;

int nShow;

HINSTANCE hInstApp;

// Optional members

LPVOID lpIDList;

LPCSTR lpClass;

HKEY hkeyClass;

DWORD dwHotKey;

HANDLE hIcon;

HANDLE hProcess;

} SHELLEXECUTEINFO, FAR *LPSHELLEXECUTEINFO;

Members

cbSize

Specifies the size, in bytes, of the structure.

fMask

This is an array of flags that indicate the content and validity of the other structure members. You can specify a combination of the following values:

Value	Meaning
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	The lpFile member is a Universal Naming Convention (UNC) path of a file on a network. Validate the share and connect to a drive letter.
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. SEE_MASK_INVOKEIDLIST overrides SEE_MASK_IDLIST.
SEE_MASK_NOCLOSEPROCESS	Leave the process running after the ShellExecuteEx function exits. The hProcess member receives the handle of the process.

hwnd

Handle to the parent window for any message boxes that the system may produce while executing this function (for example, for error reporting).

lpVerb

Pointer to 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

Pointer to a list of null-terminated strings that specify the names of the files to open or print. The function can open an executable file or a document file. The function can print a document file. If the path is not included with a name, the current directory is assumed.

lpParameters

Pointer to 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 lpFile specifies a document file, lpParameters should be NULL.

lpDirectory

Pointer to 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 the ShowWindow function. If lpFile specifies an executable file, nShow specifies how the application is to be shown when it is opened. If lpFile specifies a document file, nShow should be zero.

hInstApp

Handle to the instance of the application that was started or an error value if the application could not be started. (This handle could also be the handle of a dynamic data exchange [DDE] server application.) This member is set on return. Error values can be one of the following:

Value	Meaning
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 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 busy
SE_ERR_NOASSOC	File association not available

lpIDList

Pointer to an ITEMIDLIST structure that contains an item identifier list that uniquely identifies the file to execute. Ignored if fMask is not set to SEE_MASK_IDLIST.

lpClass

Pointer to a null-terminated string specifying the name of a file class or a globally unique identifier (GUID). Ignored if fMask is not set to SEE_MASK_CLASSNAME.

hkeyClass

Handle to the registry key for the file class. 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 the WM_SETHOTKEY message. Ignored if fMask is not set to SEE_MASK_HOTKEY.

hIcon

Handle to the icon for the file class. 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.
