Question

我想用IOpenServiceManager :: InstallService：

设置IE的默认搜索引擎提供程序

属于http://www.opensearch.org/Specifications/OpenSearch/1.1#OpenSearch_description_elements链接。我像这样创建了 SearchProviderInfo.xml ：

<?xml version="1.0" encoding="UTF-8"?>
 <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">

   <Url type="application/rss+xml"

属于http://msdn.microsoft.com/en-us/library/cc849088%28v=vs.85%29.aspx链接。我像这样创建项目“SetDefaultHelper”：

    #include <windows.h>
    #include <atlbase.h>
    #include <wininet.h>
    #include <urlmon.h>
    #include <string>
    #include "openservice.h"    
    #pragma comment(lib, "urlmon.lib")

void DisplayUsage()
{
    wprintf(L"\r\nSetDefaultHelper.exe -- Call SetDefault API on a search provider");
    wprintf(L"\r\n");
    wprintf(L"\r\nUSAGE: SetDefaultHelper.exe <option>");
    wprintf(L"\r\n");
    wprintf(L"\r\nOptions (these are mutually exclusive!):");
    wprintf(L"\r\n");
    wprintf(L"\r\n    /guid <guid>      GUID of an installed search provider");
    wprintf(L"\r\n    /url <url>        URL of an OpenSearch Description file");
    wprintf(L"\r\n");
}

int __cdecl wmain(__in int argc, __in_ecount(argc) WCHAR* argv[])
{
    HRESULT hr = E_FAIL;
    BOOL fComInitialized = FALSE;    
    if (3 != argc)
    { 
        DisplayUsage();
    }
    else if (SUCCEEDED(CoInitialize(NULL)))
    {
        fComInitialized = TRUE;
        CComPtr<IOpenServiceManager> spManager;
        hr = spManager.CoCreateInstance(CLSID_OpenServiceManager);    
        if (SUCCEEDED(hr))
        {
            CComPtr<IOpenService> spService;    
            if (0 == _wcsicmp(argv[1], L"/guid"))
            {
                // Get an IOpenService pointer from the GUID.
                WCHAR szEscaped[INTERNET_MAX_URL_LENGTH] = L"";
                DWORD cchEscaped = ARRAYSIZE(szEscaped);
                hr = UrlEscape(argv[2], szEscaped, &cchEscaped, URL_ESCAPE_SEGMENT_ONLY);    
                if (SUCCEEDED(hr))
                {                        
                    std::wstring wsOsid(L"x-osid:1:search:");
                    wsOsid += szEscaped;
                    hr = spManager->GetServiceByID(wsOsid.c_str(), &spService);
                }  
            }
            else if (0 == _wcsicmp(argv[1], L"/url"))
            {
                // Install the provider to get an IOpenService pointer.
                //CComPtr<IUri> spUri;
                //hr = CreateUri(argv[2], 0, 0, &spUri);
                //if (SUCCEEDED(hr))
                //{
                    hr = spManager->InstallService(argv[2], &spService);
                //}
            }
            else
            {
                DisplayUsage();
                hr = E_FAIL;
            }

        if (SUCCEEDED(hr))
        {
            hr = spService-&#62;SetDefault(TRUE, NULL);
        }
    }
}  

if (fComInitialized)
{
    CoUninitialize();
}

return hr;


}

我构建项目确定。文件SetDefaultHelper.exe和SearchProviderInfo.xml都是相同的文件夹。在项目设置中，设置配置属性＆gt;调试＆gt;命令Arguments = / url absolutePaht / searchProvider.xml 。然后运行调试（F10），在行“hr = CreateUri（argv [2]，0,0，＆amp; spUri）;”，rusult hr是如此陌生。我不知道为什么。你能帮帮我吗？

非常感谢。

[已解决]：
1.不需要CreateUri //评论了 2.使用绝对路径。

Answer 1

使用绝对路径和UrlCreateFromPath创建类似file:///的网址，将该网址传递给InstallService。

之间，您的XML似乎有错误。

            WCHAR szURL[MAX_PATH] = L"";
            DWORD cchURL = ARRAYSIZE(szURL);
            hr = ::UrlCreateFromPath(argv[2], szURL, &cchURL, 0);
            if (SUCCEEDED(hr))
            {
                hr = spManager->InstallService(argv[2], &spService);

                // Now we can set it as the default.
                if (SUCCEEDED(hr))
                {
                    hr = spService->SetDefault(TRUE, NULL);
                    if (hr == OS_E_CANCELLED)
                    {
                        hr = E_ACCESSDENIED;  // by the user!
                    }
                }
            }
