ShowWindow not hiding new window opened by IWebBrowser2

[jmpinchot]

Im writing an application that automates internet explorer, and am
integrating a mode that lets IE run invisibly to the user. I start
Internet Explorer with CreateProcess and the wShowWindow flag set to
SW_HIDE and everything works wonderfully. The problem arises when IE
tries to open a new window either as a result of a javascript open or
the target being set in a A tag.

Currently I'm creating the new instance of IE with CoCreateInstance,
and then calling ShowWindow(HWND, SW_HIDE) but the window still shows
up as visible.

Here's the code the creates the new window:

The caller:
IWebBrowser2 * newIE = IEBrowserControllerUtil::createBrowser(NULL,
headless);
if (newIE) {
IEBrowserControllerUtil::addNewEventSink(newIE, false,
_windowName);
*ppDisp = (IDispatch*)newIE;
}

The code the above call goes through
if (!SUCCEEDED(CoCreateInstance(CLSID_InternetExplorer, 0,
CLSCTX_SERVER, IID_IWebBrowser2,
(LPVOID*) &newIE))) {
<error cleanup code>
}

I've also tried calling CreateProcess to create the new window instead,
and setting the Visible property of the IWebBrowser2 instance; I get
the same result, the window is still visible to the user.

Is there something I'm missing? Any help would be greatly appreciated.

Hi JM,

The correct newsgroup for your question is
microsoft.public.inetsdk.programming.webbrowser_ctl

but that aside, some popup blockers force popup windows to open in the
background. Try turning off your popup blocker... You will have to find a
way to defeat this in your final app... remember to test, test, test.

Regards.
