可以把swf文件放到資源中，在需要執行swf文件時，

1 把swf從資源中加載到內存中

2 把swf的內容傳給flash 控件，然后開始播放。

具體的方法是：從flash對象中獲取IID_IPersistStreamInit,用這個接口來把swf的文件內容傳遞給flash控件

IUnknown* u = _flash.GetControlUnknown();

if(u != NULL)

{

IPersistStreamInit* psi;

HRESULT hr = u->QueryInterface(IID_IPersistStreamInit, reinterpret_cast(&psi));

if(SUCCEEDED(hr))

{

HRSRC res = FindResource(NULL, MAKEINTRESOURCE(IDR_SWF), "SWF");

HGLOBAL h = LoadResource(NULL, res);

unsigned int len = SizeofResource(NULL, res);

if(! load_movie_from_stream(psi, reinterpret_cast(LockResource(h)), len))

{

}

psi->Release();

}

}

bool load_movie_from_stream(IPersistStreamInit* psi, unsigned char* data, unsigned int len)

{

bool successful = false;

bool compressed = false;

unsigned char* buffer = NULL;

unsigned int movie_size;

ULARGE_INTEGER size, cb;

LARGE_INTEGER li;

memmove(&movie_size, data + 4, 4);

__try

{

//compressed?

if(memcmp(data, "CWS", 3) == 0)

{

compressed = true;

unsigned long d_len;

buffer = new unsigned char[movie_size];

memmove(buffer, data, 8);

buffer[0] = 'F';

int r = uncompress(buffer + 8, &d_len, data + 8, len - 8);

if(r != Z_OK)

{

__leave;

}

}

else

{

buffer = data;

}

//save movie template

psi->GetSizeMax(&size);

HGLOBAL h1 = GlobalAlloc(GMEM_MOVEABLE, size.LowPart);

IStream* s1;

CreateStreamOnHGlobal(h1, FALSE, &s1);

psi->Save(s1, TRUE);

//insert movie into template

HGLOBAL h2 = GlobalAlloc(GMEM_MOVEABLE, size.LowPart + movie_size);

IStream* s2;

CreateStreamOnHGlobal(h2, FALSE, &s2);

//magic flag. "gUfU" means no movie loaded, "fUfU" means movie loaded

s2->Write("f", 1, NULL);

li.HighPart = 0;

li.LowPart = 1;

s1->Seek(li, SEEK_SET, NULL);

cb.HighPart = 0;

cb.LowPart = 3;

s1->CopyTo(s2, cb, NULL, NULL);

//write movie size

s2->Write(&movie_size, 4, NULL);

//write movie

s2->Write(buffer, movie_size, NULL);

cb.HighPart = 0;

cb.LowPart = size.LowPart - 4;

s1->CopyTo(s2, cb, NULL, NULL);

//load movie

li.HighPart = 0;

li.LowPart = 0;

s2->Seek(li, SEEK_SET, NULL);

psi->Load(s2);

s1->Release();

s2->Release();

GlobalFree(h1);

GlobalFree(h2);

successful = true;

}

__finally

{

if(compressed && buffer != NULL)

{

delete[] buffer;

}

}

return successful;

}
