) As Integer
用法
Dim instance As IPersistFileFormat
Dim pszFilename As String
Dim grfMode As UInteger
Dim fReadOnly As Integer
Dim returnValue As Integer

returnValue = instance.Load(pszFilename, _

int Load(
    string pszFilename,
    uint grfMode,
    int fReadOnly
)

int Load(
    [InAttribute] String^ pszFilename, 
    [InAttribute] unsigned int grfMode, 
    [InAttribute] int fReadOnly
)

abstract Load : 
        pszFilename:string * 
        grfMode:uint32 * 
        fReadOnly:int -> int

    grfMode : uint, 
    fReadOnly : int
) : int

Parameters

pszFilename
Type: System.String
[in] Pointer to the name of the file to load, which, for an existing file, should always include the full path.

grfMode
Type: System.UInt32
[in] File format mode. If zero, the object uses the usual defaults as if the user had opened the file.

fReadOnly
Type: System.Int32
[in] true indicates that the file should be opened as read-only.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
