The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
Constant | Description | Notes |
---|---|---|
CLSCTX_INPROC_SERVER (int) | The code that creates and manages objects of this class is a DLL that runs in the same process as the caller of the function specifying the class context. | |
CLSCTX_INPROC_HANDLER (int) | The code that manages objects of this class is an in-process handler. This is a DLL that runs in the client process and implements client-side structures of this class when instances of the class are accessed remotely. | |
CLSCTX_LOCAL_SERVER (int) | The EXE code that creates and manages objects of this class runs on same machine but is loaded in a separate process space. | |
CLSCTX_REMOTE_SERVER (int) | A remote context. The code that creates and manages objects of this class is run on a different computer. | |
CLSCTX_SERVER (int) | Indicates server code, whether in-process, local, or remote. This definition ORs CLSCTX_INPROC_SERVER , CLSCTX_LOCAL_SERVER , and CLSCTX_REMOTE_SERVER . | |
CLSCTX_ALL (int) | Indicates all class contexts. This definition ORs CLSCTX_INPROC_HANDLER and CLSCTX_SERVER . | |
VT_NULL (int) | NULL pointer reference. | |
VT_EMPTY (int) | A property with a type indicator of VT_EMPTY has no data associated with it; that is, the size of the value is zero. | |
VT_INT (int) | 4-byte signed integer value (equivalent to VT_I4 ). | |
VT_I1 (int) | 1-byte signed integer. | |
VT_I2 (int) | Two bytes representing a 2-byte signed integer value. | |
VT_I4 (int) | 4-byte signed integer value. | |
VT_I8 (int) | 8-byte signed integer value. | x64 only |
VT_UINT (int) | 4-byte unsigned integer (equivalent to VT_UI4 ). | |
VT_UI1 (int) | 1-byte unsigned integer. | |
VT_UI2 (int) | 2-byte unsigned integer. | |
VT_UI4 (int) | 4-byte unsigned integer. | |
VT_UI8 (int) | 8-byte unsigned integer. | x64 only |
VT_R4 (int) | 32-bit IEEE floating point value. | |
VT_R8 (int) | 64-bit IEEE floating point value. | |
VT_BOOL (int) | Boolean value. | |
VT_ERROR (int) | Error code; containing the status code associated with the error. | |
VT_CY (int) | 8-byte two's complement integer (scaled by 10,000). | |
VT_DATE (int) | A 64-bit floating point number representing the number of days (not seconds) since December 31, 1899 . For example, January 1, 1900 is 2.0 , January 2, 1900 is 3.0 , etc. This is stored in the same representation as VT_R8 . | |
VT_BSTR (int) | Pointer to a null-terminated Unicode string. | |
VT_DECIMAL (int) | A decimal structure. | |
VT_UNKNOWN (int) | A pointer to an object that implements the IUnknown interface. | |
VT_DISPATCH (int) | A pointer to a pointer to an object was specified. | |
VT_VARIANT (int) | A type indicator followed by the corresponding value. VT_VARIANT can be used only with VT_BYREF . | |
VT_ARRAY (int) | If the type indicator is combined with VT_ARRAY by an OR operator, the value is a pointer to a SAFEARRAY . VT_ARRAY can use the OR with the following data types: VT_I1 , VT_UI1 , VT_I2 , VT_UI2 , VT_I4 , VT_UI4 , VT_INT , VT_UINT , VT_R4 , VT_R8 , VT_BOOL , VT_DECIMAL , VT_ERROR , VT_CY , VT_DATE , VT_BSTR , VT_DISPATCH , VT_UNKNOWN and VT_VARIANT . | |
VT_BYREF (int) | If the type indicator is combined with VT_BYREF by an OR operator, the value is a reference. Reference types are interpreted as a reference to data, similar to the reference type in C++. | |
CP_ACP (int) | Default to ANSI code page. | |
CP_MACCP (int) | Macintosh code page. | |
CP_OEMCP (int) | Default to OEM code page. | |
CP_UTF7 (int) | Unicode (UTF-7). | |
CP_UTF8 (int) | Unicode (UTF-8). | |
CP_SYMBOL (int) | SYMBOL translations. | |
CP_THREAD_ACP (int) | Current thread's ANSI code page | |
VARCMP_LT (int) | The left bstr is less than right bstr . | |
VARCMP_EQ (int) | The two parameters are equal. | |
VARCMP_GT (int) | The left bstr is greater than right bstr . | |
VARCMP_NULL (int) | Either expression is NULL. | |
NORM_IGNORECASE (int) | Ignore case sensitivity. | |
NORM_IGNORENONSPACE (int) | Ignore nonspacing characters. | |
NORM_IGNORESYMBOLS (int) | Ignore symbols. | |
NORM_IGNOREWIDTH (int) | Ignore string width. | |
NORM_IGNOREKANATYPE (int) | Ignore Kana type. | |
NORM_IGNOREKASHIDA (int) | Ignore Arabic kashida characters. | Availability is dependent upon under lying library. |
DISP_E_DIVBYZERO (int) | A return error that indicates a divide by zero error. | |
DISP_E_OVERFLOW (int) | An error that indicates that a value could not be coerced to its expected representation. | |
DISP_E_BADINDEX (int) | An error that indicates that an array index does not exist. | |
DISP_E_PARAMNOTFOUND (int) | A return value that indicates that one of the parameter IDs does not correspond to a parameter on the method. | |
MK_E_UNAVAILABLE (int) | iMoniker COM status code, return on errors where the function call failed due to unavailability. | |
LOCALE_NEUTRAL (int) | The neutral locale. This constant is generally not used when calling NLS APIs. Instead, use LOCALE_SYSTEM_DEFAULT. | |
LOCALE_SYSTEM_DEFAULT (int) | The default locale for the operating system. |
