IE Launching in windows

[frenchfry164]

How do I launch a internet explorer window in windows, that starts out in the URL I specify?

BTW: I am using allegro, so some things I can't include (allegro likes to overdo windows stuff)

I think this works. Ok well it might work, I didn't compile it. But is should work on VC, and maybe it also works on other compilers.
I dunno, try it.

#include <windows.h>
// Internet Explorer's IID
IID const IID_IWebBrowserApp={0x0002DF05,0x0000,0x0000,0xC0, 0x00,0x00,0x00,0x00,0x00,0x00,0x46};

void InternetExplorerNav(CString & str)
{
HRESULT hResult;
IWebBrowserApp* pBrowser;
VARIANT vFlags = {0};
VARIANT vTargetFrameName = {0};
VARIANT vPostData = {0};
VARIANT vHeaders = {0};

BSTR pURL = str.AllocSysString();

if (FAILED(hResult=CoInitialize(NULL)))
{ // failure message
}

if (FAILED(hResult = CoCreateInstance(
CLSID_InternetExplorer, NULL, CLSCTX_SERVER,
IID_IWebBrowserApp, (LPVOID*)&pBrowser)))
{ // some error messag
}

if (FAILED(pBrowser->Navigate(pURL,&vFlags, &vTargetFrameName, &vPostData, &vHeaders)))
{
// failure message
}


if ( pBrowser ) pBrowser->Release();

CoUninitialize();

I can't include windows.h, it conflicts with allegro.h

[Dual-Catfish]

Use CreateProcess()
But then again, that's defined in windows.h

Try using system("iexplore.exe -o webpage");
and remember to include stdlib.h

i didnt know what files to show here, so i put the view.cpp and the view.h code.this opens a window with a slitter bar in the middle,search engine on the right, when you search, it shows it on the left, but you can change the default opening page to whatever you want it to be.im using msvc++ 6, and i have to include webbrowser.h to get this to work

Whoopee!!!! Its one of those competitions for finding the most painfull ways of doing a rather mundane task.......

Not having much time to play....here's my submission

#include <Shellapi.h>
//Dont forget Shell32.lib


int WINAPI WinMain(HINSTANCE hThisInstance,
                   HINSTANCE hPrevInstance,
                   LPSTR lpszArgument,
                   int nShowState)
{
    ShellExecute(HWND_DESKTOP, 
                 "OPEN",
                 "http://www.cprogramming.com",
                 NULL,
                 NULL,
                 SW_SHOWNORMAL);  
  return 0;
}

Not as cool as the COM and MFC examples, but hell!!!!....I'm busy

[frenchfry164]

you can use system() in windows? It's defined in dos.h, so I don't think you can.

[frenchfry164]

the system() method did not work, as I thought it wouldn't. It just minimizes my game. I used both dos.h and stdlib.h system()'s and it didn't work.

I need a simple way to do this. I just want to make it to where if you click the logo in the main menu of my game it opens up IE and goes to http://frenchfry164.tripod.com

[Fordy]

Er....did you try the ShellExecute() method??

[frenchfry164]

what's that?

Jeez....

Read my previous post

[frenchfry164]

well I don't have Shell32.lib because I use Dev-C++, and it doesn't come with ANY .lib files.

Try libshell32.a
