如何将图标句柄保存成图标文件?

[AttaBoy]

如我在资源中定义一图标

IDI_ICON1,如何在程序中将其再保存成1.ico

[speakboy]

DWORD nNumber;
HANDLE hFile;
char *ico_handle;
HRSRC h = FindResource(NULL,IDI_ICON1,Icon);
HGLOBAL h1 = LoadResource(NULL,h);
ico_handle=(char *)LockResource(h1);
hFile = CreateFile("l.ico",GENERIC_WRITE,0,NULL,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
WriteFile(hFile,ico_handle,20//你的图标文件的大小,&nNumber,NULL);
CloseHandle(hFile);

我试试去，有效立即给分

[AttaBoy]

我是这样写的

HRSRC h = FindResource(NULL,MAKEINTRESOURCE(IDI_ICON_ZL),RT_ICON);

为什么返回值h是空？？？？？

帮帮忙，好不好？

您好！我试啦，用刚刚我告诉你的方法不行，但你可以换一个方法，
用Windows API的 ExtractIcon()函数来做到！

use OleCreatePictureIndirect to get IStream from hicon, then use IPicture::SaveAsFile to save it.
Saving an Image to a Stream

void SaveThePicture(IUnknown* pUnk)
{
IPicture* pPicture = 0;

HRESULT hr = pUnk->QueryInterface(&pPicture);

if(SUCCEEDED(hr))
{
IStorage* pStg = 0;

hr = ::StgCreateDocfile(L"c:\\picttest",
STGM_SHARE_EXCLUSIVE |
STGM_CREATE |
STGM_READWRITE,
0, &pStg);
if(SUCCEEDED(hr))
{
IStream* pStream = 0;

hr = pStg->CreateStream(L"PICTURE",
STGM_SHARE_EXCLUSIVE |
STGM_CREATE |
STGM_READWRITE,
0, 0, &pStream);
if(SUCCEEDED(hr))
{
hr = pPicture->SaveAsFile(pStream,
TRUE, // save mem copy
NULL);
pStream->Release();
}
pStg->Release();
}
pPicture->Release();
}
}

看看MSDN的ICONPRO的例子
