IsSearchSynchronous在Outlook中失败

问题描述：

我正在使用Outlook自动查找日历中的项目。为此，我使用IsSearchSynchronous（）方法来查看是否必须等待AdvancedSearchComplete事件。顺便说一句，它是否有同步？IsSearchSynchronous在Outlook中失败

无论如何，如果我有Outlook运行，我没有这个电话的问题。但是，如果它不运行 - 呼叫失败

HRESULT: 0x80020009 Exception occurred

的EXCEPINFO包含：

Source: "Microsoft Outlook" 
Description: "The operation failed." 
scode: 0x80004005

有什么建议？这里是我的测试案例：

#include <atlstr.h> 

int _tmain() 
{ 
    IDispatch* pApp; 
    HRESULT  hr; 
    CoInitialize(NULL); 
    CLSID clsid; 
    hr = CLSIDFromProgID(L"Outlook.Application", &clsid); 
    if(SUCCEEDED(hr)) 
    { 
     hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_IDispatch, (void **)&pApp); 
     if(SUCCEEDED(hr)) 
     { 
      // Get DISPID for "IsSearchSynchronous" 
      OLECHAR Name[] = {L"IsSearchSynchronous"}; 
      LPOLESTR lp = Name; 
      DISPID dispID; 
      hr = pApp->GetIDsOfNames(IID_NULL, &lp, 1, LOCALE_USER_DEFAULT, &dispID); 
      if(SUCCEEDED(hr)) 
      { 
       // The path name of the folders that the search will search through. 
       VARIANT path; 
       path.vt = VT_BSTR; 
       path.bstrVal = SysAllocString(L"'Calendar'"); 

       // Build DISPPARAMS 
       DISPPARAMS dp = { NULL, NULL, 0, 0 }; 
       dp.cArgs = 1; 
       dp.rgvarg = &path; 

       // get IsSearchSynchronous 
       VARIANT result; 
       VariantInit(&result); 
       EXCEPINFO ei = {0}; 
       hr = pApp->Invoke(dispID, IID_NULL, LOCALE_SYSTEM_DEFAULT, DISPATCH_PROPERTYGET, &dp, &result, &ei, NULL); 
       VARIANT_BOOL vbIsSearchSynchronous = result.boolVal; 
      } 
     } 
    } 
    CoUninitialize(); 
    return 0; 
}

答

如果任何人有兴趣，这是与微软帮助解决。对于IsSearchSynchronous（）调用的“范围”参数应该是日历文件夹的完整路径，例如：

"\\Mailbox - <user_name>\\Calendar"
