下面是msdn上有关DirectShow的一段代码，调不通？
不知道还要加些什么头文件？
int _tmain(int argc, _TCHAR* argv[])
{
IGraphBuilder *pGraph = NULL;
IMediaControl *pControl = NULL;
IMediaEvent *pEvent = NULL;

// Initialize the COM library.
HRESULT hr = CoInitialize(NULL);
if (FAILED(hr))
{
printf( "ERROR - Could not initialize COM library ");
return 0;
}

// Create the filter graph manager and query for interfaces.
hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER,
IID_IGraphBuilder, (void **)&pGraph);
if (FAILED(hr))
{
printf( "ERROR - Could not create the Filter Graph Manager. ");
return 0;
}

hr = pGraph-> QueryInterface(IID_IMediaControl, (void **)&pControl);
hr = pGraph-> QueryInterface(IID_IMediaEvent, (void **)&pEvent);

// Build the graph. IMPORTANT: Change this string to a file on your system.
hr = pGraph-> RenderFile(L "C:\\Example.avi ", NULL);
if (SUCCEEDED(hr))
{
// Run the graph.
hr = pControl-> Run();
if (SUCCEEDED(hr))
{

long evCode;

// Note: Do not use INFINITE in a real application, because it
// can block indefinitely.

pGraph-> Release();

return 0;
}

[解决办法]
装了sdk没有?
[解决办法]
#include <dshow.h >
#pragma comment(lib, "Strmiids.lib ")
[解决办法]
1.装DX SDK没?
没装那就去下吧.
2.让编译器包含软件开发包的目录没?
首先点击Tool菜单，选择Options，然后点击Directories，在Show Directories for 组合框下拉菜单中选择Include files，增加一个新的目录。将你的DirectX的路径填入。（例如：C:\DXSDK\include）然后将它移到列表的第一位，使编译时第一个寻找它（防止寻找老版本）。然后选择Show Directories for组合框下拉菜单中的Library files，方法同前，只是把include改成lib。
3.添加库文件名到你的工程没?
Project -> Settings -> Link ,在Object/library modules中加入你要用到的.lib文件

如果还不行的话那我就没折了...
