GetStateTextA function (oleacc.h)
Retrieves a localized string that describes an object's state for a single predefined state bit flag. Because state values are a combination of one or more bit flags, clients call this function more than once to retrieve all state strings.
Syntax
UINT GetStateTextA(
[in] DWORD lStateBit,
[out] LPSTR lpszState,
[in] UINT cchState
);
Parameters
[in] lStateBit
Type: DWORD
One of the object state constants.
[out] lpszState
Type: LPTSTR
Address of a buffer that receives the state text string. If this parameter is NULL, the function returns the state string's length, not including the null character.
[in] cchState
Type: UINT
The size of the buffer that is pointed to by the lpszStateBit parameter. For ANSI strings, this value is measured in bytes; for Unicode strings, it is measured in characters.
Return value
Type: UINT
If successful, and if lpszStateBit is non-NULL, the return value is the number of bytes (ANSI strings) or characters (Unicode strings) that are copied into the buffer, not including the null-terminated character. If lpszStateBit is NULL, the return value represents the string's length, not including the null character.
If the string resource does not exist, or if the lpszStateBit parameter is not a valid pointer, the return value is zero (0). To get extended error information, call GetLastError.
Remarks
This function accepts only one state bit at a time, not a bitmask.
Note
The oleacc.h header defines GetStateText as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
