Thread: Web browser Control

'Lo -

I'm new to the forum - been reading it for some time. However, I finally have a question that I haven't been able to solve elsewhere:

Now that I have delved into the Win32 API, I would like to find some resources on how to connect to a web server through my win32 C app. Basically I want to be able to connect to my website(s), access a PHP script that displays an image, and display that image in the application.

Any help/resources/tutorials on the subject would be greatly appreciated.

Ay thank you

There is a few ways to do this. If you just want to display a web page in a dialog, try this:

Code:

#include <windows.h>
#include <Urlmon.h>
#include <mshtmhst.h>

int main() {
  SHOWHTMLDIALOGFN* pfnShowHTMLDialog;
  HINSTANCE hinstMSHTML = LoadLibrary(TEXT("MSHTML.DLL"));

   if (hinstMSHTML == NULL)
   {
       // Error loading module -- fail as securely as possible
       return 0;
   }
   
   pfnShowHTMLDialog = (SHOWHTMLDIALOGFN*)GetProcAddress(hinstMSHTML,
                                                              TEXT("ShowHTMLDialog"));
   if (pfnShowHTMLDialog)
   {
       IMoniker *pURLMoniker;
       BSTR bstrURL = SysAllocString(L"http://www.cboard.cprogramming.com");
       CreateURLMoniker(NULL, bstrURL, &pURLMoniker);

       if (pURLMoniker)
       {
           (*pfnShowHTMLDialog)(NULL, pURLMoniker, NULL, NULL, NULL);
           pURLMoniker->lpVtbl->Release(pURLMoniker);
       }

       SysFreeString(bstrURL);
   }

   FreeLibrary(hinstMSHTML);

  return 0;
}

Alternatively, for simplicity you can use UrlDownloadToFile or OleLoadPicturePath.

I don't have that mshtmhst.h header file. How can I do it then?

Remove the #include <mshtmhst.h> line and add this line instead.

Code:

typedef HRESULT STDAPICALLTYPE SHOWHTMLDIALOGFN (HWND hwndParent, IMoniker *pmk, VARIANT *pvarArgIn, WCHAR* pchOptions, VARIANT *pvArgOut);

But I still get one error:

Code:

25 C:\Programs\Dev-Cpp\Templates\webcontrol.cpp 'struct IMoniker' has no member named 'lpVtbl'

Either compile the code as C rather than C++ or change the line:

Code:

          pURLMoniker->lpVtbl->Release(pURLMoniker);
to:
          pURLMoniker->Release();

What library I should include?

Code:

[Linker error] undefined reference to `SysAllocString@4'
[Linker error] undefined reference to `CreateURLMoniker@12'
[Linker error] undefined reference to `SysFreeString@4'

I know it uses lib prefix, but I didn't find any library that contains urlmon in the filename...
And what free ones are you talking about?

Why the hell is a thread from 2003 being revived?
