Couldn't get any input from the "Mobile Development" board, so now I turn to the COM giants here 
The docs on this are sparse, to say the least...
My problem: I'm trying to embed a WebBrowser object in a Windows Mobile application. I can create it and query its size and window handle, but IWebBrowser2::Navigate2 fails with E_FAIL.
Can anyone give me any hints to why it fails?
Code (yes, C++):
My host control is declared like this:
class HtmlControl : public Window
{
public:
HtmlControl(HWND window)
: Window(window)
, iOleObject_(NULL)
{
iOleSite_.host = this;
iOleFrame_.host = this;
CreateWebControl();
}
Site iOleSite_;
Frame iOleFrame_;
IOleObject* iOleObject_;
private:
void CreateWebControl();
};Where Site and Frame are declared like this:
struct Site : public IOleClientSite,
public IOleInPlaceSite
{
HtmlControl* host;
STDMETHODIMP QueryInterface(REFIID riid, void** ppvObject);
STDMETHODIMP_(ULONG) AddRef();
STDMETHODIMP_(ULONG) Release();
STDMETHODIMP SaveObject();
STDMETHODIMP GetMoniker(DWORD dwAssign, DWORD dwWhichMoniker,
IMoniker** ppmk);
STDMETHODIMP GetContainer(LPOLECONTAINER FAR* ppContainer);
STDMETHODIMP ShowObject();
STDMETHODIMP OnShowWindow(BOOL fShow);
STDMETHODIMP RequestNewObjectLayout();
STDMETHODIMP GetWindow(HWND FAR* lphwnd);
STDMETHODIMP ContextSensitiveHelp(BOOL fEnterMode);
STDMETHODIMP CanInPlaceActivate();
STDMETHODIMP OnInPlaceActivate();
STDMETHODIMP OnUIActivate();
STDMETHODIMP GetWindowContext(LPOLEINPLACEFRAME FAR* lplpFrame,
LPOLEINPLACEUIWINDOW FAR* lplpDoc,
LPRECT lprcPosRect,
LPRECT lprcClipRect,
LPOLEINPLACEFRAMEINFO lpFrameInfo);
STDMETHODIMP Scroll(SIZE scrollExtent);
STDMETHODIMP OnUIDeactivate(BOOL fUndoable);
STDMETHODIMP OnInPlaceDeactivate();
STDMETHODIMP DiscardUndoState();
STDMETHODIMP DeactivateAndUndo();
STDMETHODIMP OnPosRectChange(LPCRECT lprcPosRect);
};
struct Frame : public IOleInPlaceFrame
{
HtmlControl* host;
STDMETHODIMP QueryInterface(REFIID riid, void** ppvObject);
STDMETHODIMP_(ULONG) AddRef();
STDMETHODIMP_(ULONG) Release();
STDMETHODIMP GetWindow(HWND FAR* lphwnd);
STDMETHODIMP ContextSensitiveHelp(BOOL fEnterMode);
STDMETHODIMP GetBorder(LPRECT lprectBorder);
STDMETHODIMP RequestBorderSpace(LPCBORDERWIDTHS pborderwidths);
STDMETHODIMP SetBorderSpace(LPCBORDERWIDTHS pborderwidths);
STDMETHODIMP SetActiveObject(IOleInPlaceActiveObject* pActiveObject,
LPCOLESTR pszObjName);
STDMETHODIMP InsertMenus(HMENU hmenuShared,
LPOLEMENUGROUPWIDTHS lpMenuWidths);
STDMETHODIMP SetMenu(HMENU hmenuShared, HOLEMENU holemenu,
HWND hwndActiveObject);
STDMETHODIMP RemoveMenus(HMENU hmenuShared);
STDMETHODIMP SetStatusText(LPCOLESTR pszStatusText);
STDMETHODIMP EnableModeless(BOOL fEnable);
STDMETHODIMP TranslateAccelerator(LPMSG lpmsg, WORD wID);
};The implementations of Site and Frame will be provided if needed, so that this space isn't cluttered too much.
So, the interesting function here is HtmlControl::CreateWebControl(). Let's walk it through, so that the possible strangeness of the IWebBrowser2::Navigate2 failure can be better seen.
First, an instance of the WebBrowser COM object is created and its associated IOleObject is retrieved:
IUnknown* iUnknown = NULL;
HRESULT hr = ::CoCreateInstance(CLSID_WebBrowser,
NULL,
CLSCTX_INPROC_SERVER | CLSCTX_INPROC_HANDLER,
IID_IUnknown,
(void*)(&iUnknown));
VERIFY(SUCCEEDED(hr));
hr = iUnknown->QueryInterface(IID_IOleObject, (void*)(&iOleObject_));
VERIFY(SUCCEEDED(hr));These operations were all successful in the sense that hr == S_OK.
After getting the WebControl object, I want to show/activate it using our IOleClientSite implementation:
hr = iOleObject_->SetClientSite(&iOleSite_);
VERIFY(SUCCEEDED(hr));
const RECT rect = GetClientRect();
hr = iOleObject_->DoVerb(OLEIVERB_SHOW, NULL, &iOleSite_, 0, GetHwnd(), &rect);
VERIFY(SUCCEEDED(hr)); These operations were also successful in the sense that hr == S_OK. However, the end result (the IWebBrowser2::Navigate2 failure) occurs also if OLEIVERB_SHOW is changed to OLEIVERB_UIACTIVATE or OLEIVERB_INPLACEACTIVATE.
Next, I dig the IWebBrowser2 out of the WebControl object and checks if the browser HWND is sane:
IWebBrowser2* iWebBrowser = NULL;
hr = iOleObject_->QueryInterface(IID_IWebBrowser2, (void**)&iWebBrowser);
VERIFY(SUCCEEDED(hr));
HWND hwndBrowser = NULL;
hr = iWebBrowser->get_HWND((long*)&hwndBrowser);
VERIFY(SUCCEEDED(hr));
VERIFY(hwndBrowser != NULL);
VERIFY(::GetParent(hwndBrowser) == GetHwnd());
IOleWindow* iOleWindow = NULL;
hr = iOleObject_->QueryInterface(IID_IOleWindow, (void*)(&iOleWindow));
VERIFY(SUCCEEDED(hr));
hwndBrowser = NULL;
hr = iOleWindow->GetWindow(&hwndBrowser);
VERIFY(hwndBrowser != NULL);
VERIFY(::GetParent(hwndBrowser) == GetHwnd()); Again, these operations were successful in the sense that hr == S_OK. Also, the browser HWND is equal in both method 1 and 2 and its parent is indeed our host control. I see this as some kind of indication that something works.
But... the thing I need doesn't work; the precious IWebBrowser2::Navigate2:
VARIANT vURL;
vURL.vt = VT_BSTR;
vURL.bstrVal = ::SysAllocString(L"about:blank");
VARIANT vEmpty;
vEmpty.vt = VT_EMPTY;
hr = iWebBrowser->Navigate2(&vURL, &vEmpty, &vEmpty, &vEmpty, &vEmpty);
VERIFY(SUCCEEDED(hr)); Now I get hr == E_FAIL.
I cannot really see the problem, since everything up to this point worked successfully, and the last call seems trivial.
Is anyone still around all the way down here with some guess as to what might be going on?
Thanks for any input!

There's a article here on how to host the web browser via C code and the author does an *EXCELLENT* job of walking you through exactly what has to happen - try and look for that, maybe it will off you hints as to what's missing.

PS if you can't find the article I wrote code for C++ on the desktop (don't know how applicable it is to embedded) that does wrap the web browser:
Win32WebBrowserHost.h[^]
Maybe that will help a bit?

Sure are mate. I'd hate to imagine what it would cost if I'd been required to pay for all that I've learned from this wonderful site.
You've certainly contributed to that which I know Iain.

but it is not deleting my folder...
How can i do it????
Thanks in advance

Try this in CMD
rd /s FOLDER
i think it will work

But i want to do it through coding...

While you can do what Shirani's suggests via code, it's definitely the wrong aproach.

See Here[^]
Edit: Sorry, that was the CE-version.
See Here instead[^]
An interesting piece of information from that page is:

have you only checked the API Documentation[^] ?
"lpPathName : The path of the directory to be removed. This path must specify an empty directory, and the calling process must have delete access to the directory. "
down further the page, you can see this :
"To recursively delete the files in a directory, use the SHFileOperation[^] function."
next time, google before asking please

I like to Delete folder in any case even if other applications or other users are accessing the same folder. Forcefully i like to delete the Folder. I receive Error 32 when the function SHFileOperation(). Can any one tell me how can i acheive this.

hi
I need to write a program that needs to "steel" the data that appers on a control box of a diffrent program.
I saw how the SPY programs here are built but they all need a user interface to point to that control.
I want to go throgh all the process that are running and check if what i want is there and then get it's handle.
Visual studio spy++ does something like that. but how???
please help me i am trying to fins a solution for a long time.
Thank you

Do you want to make a program like SPY++?

i want i program that will tell me what is the value in the calculator(for example) text box. the UI shouls be output only.
the way i thought of doing this was to go through all the process and when i reach to right one check it's window handle's. but i don't how to get the process's list and how to get the handles from the process.
|
|
|
|
|
For start you can use EnumWindows for get handle for each process and for more functions that you will be help them see Process and Thread Functions[^].

Or maybe a password text box??

I think its not possible for all programs.

Since your intentions are so honest, I'm going to help you: have a look at EnumWindows [^] function.

Try something like this:
#include "stdafx.h"
#include <tchar.h>
#include <malloc.h>
#include <windows.h>
#include <iostream>
using namespace std;
int main(int argc, char* argv[])
{
HWND hwndCalc = FindWindow(_T("SciCalc"), _T("Calculator"));
if (hwndCalc == NULL)
{
cerr << "Couldn't find the Calculator window!" << endl;
return -1;
}
HWND hwndEdit = FindWindowEx(hwndCalc, NULL, _T("Edit"), NULL);
if (hwndEdit == NULL)
{
cerr << "Couldn't find the Calculator's edit control!" << endl;
return -2;
}
int len = SendMessage(hwndEdit, WM_GETTEXTLENGTH, 0, 0);
if (len == 0)
{
cerr << "Text empty?!?" << endl;
return -3;
}
LPTSTR pBuffer = static_cast<LPTSTR>(_alloca((len+1)*sizeof(TCHAR)));
int res = SendMessage(hwndEdit, WM_GETTEXT, len+1, reinterpret_cast<LPARAM>(pBuffer));
if (res == 0)
{
cerr << "Text empty?!?" << endl;
return -4;
}
#ifdef UNICODE
wcout << _T("Calculator's result: ") << pBuffer << endl;
#else
cout << _T("Calculator's result: ") << pBuffer << endl;
#endif
return 0;
}
It's a console application.

CImage m;
m.Load(_T("c:\\1.jpg"));
m_Button.SetBitmap(m.detach());
but if you want to use of bitmaps you can use of LoadImage.
