c++ - 将整数分配给变体

Question

我想将 Flag 设置为 navOpenInBackgroundTab of BrowserNavConstants enum很快将作为参数传递给 IWebBrowser2::Navigate2 Method .

IWebBrowser2::Navigate2 的签名:-

HRESULT Navigate2(
    VARIANT *URL,
    VARIANT *Flags,
    VARIANT *TargetFrameName,
    VARIANT *PostData,
    VARIANT *Headers
);

这是我遇到的问题:-

VARIANT SITE={0}, vFlags = {0},vTargetFrameName = {0},vPostData = {0},vHeaders = {0};
...
...
vFlags.intVal=navOpenInBackgroundTab;//<--Here,Don't know how to do it.Not Working..

m_spWebBrowser->Navigate2(&SITE, &vFlags,&vTargetFrameName, &vPostData, &vHeaders);

非常感谢您的支持。

使用InitVariantFromInt32 :-

HRESULT hr = InitVariantFromInt32(navOpenInBackgroundTab, &vFlags);

您也可以使用(来 self 的旧代码库:)):-

V_VT(&vFlags) = VT_I4;
V_I4(&vFlags) = navOpenInBackgroundTab;
