IExtractIcon::Extract

[Now Supported on Windows NT]

Extracts an icon image from the specified location.

HRESULT Extract(

LPCSTR pszFile,	//Points to the icon location specifier
UINT nIconIndex,	//Icon index
HICON *phiconLarge,	//Points to variable for large icon handle
HICON *phiconSmall,	//Points to variable for small icon handle
UINT nIconSize	//Specifies the size of the large icon required
);

Parameters

pszFile

Pointer to a null-terminated string specifying the icon location.

nIconIndex

Icon index.

phiconLarge and phiconSmall

Pointer to the variable that receives the handle of the large icon.

phiconSmall

Pointer to the variable that receives the handle of the small icon.

nIconSize

Value specifying the size, in pixels, of the icon required. The LOWORD and HIWORD specify the size of the large and small icons, respectively. The size specified can be the width or height. The width of an icon always equals its height.

Return Values

Returns NOERROR if the function extracted the icon or S_FALSE if the calling application should extract the icon.

Remarks

The icon location and index are the same values returned by the IExtractIcon::GetIconLocation method. If this function returns S_FALSE, these values must specify an icon filename and index that form legal parameters for a call to ExtractIcon. If this function does not return S_FALSE, the calling application should make no assumptions about the meanings of the pszFile and nIconIndex parameters.
