Syntax

'Declaration
Function GetImmCompositionString ( _
    HIMC As UInteger, _

int GetImmCompositionString(
    uint HIMC,
    uint dwIndex,
    out string pbstrCompString,
    out int plRetVal

int GetImmCompositionString(
    [InAttribute] unsigned int HIMC, 
    [InAttribute] unsigned int dwIndex,

abstract GetImmCompositionString : 
        HIMC:uint32 * 
        dwIndex:uint32 *

function GetImmCompositionString(
    HIMC : uint, 
    dwIndex : uint, 
    pbstrCompString : String, 
    plRetVal : int
) : int

Parameters

HIMC
Type: UInt32

[in] Handle to the IME context.

dwIndex
Type: UInt32

[in] Index of the information to retrieve. For more information about possible values, see IME Composition String Values.

pbstrCompString
Type: String%

[out] Binary buffer—not a Unicode string. Allocated using SysAllocStringByteLen. For more information, see ImmSetCompositionString

and ImmGetCompositionString.

plRetVal
Type: Int32%

[out] Pointer to the return value. Contains the number of bytes copied to the destination buffer or, if dwBufLen is zero, the buffer size, in bytes, needed to receive all of the information. The size is always in bytes, even if the requested data is a Unicode string.

On error, set to one of the two values: IMM_ERROR_NODATA, or IMM_ERROR_GENERAL.

Return Value

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