GetDlgItem(IDC_RADIO_BUTTON)->ShowWindow(false);

I think this is the way I normally do it.

IStream ?

Hello!

I'm trying to record a metafile under Gdi+ somehow into MEMORY, but all the constructors for Gdiplus::Metafile require a filename! WTF | :WTF:

There is however one constructor which allows the metafile to be recorded into an IStream interface. I was thinking that perhaps such an object could be written that would stream the data into a memory buffer via an IStream interface.

<br />
Metafile::Metafile(IStream* stream, HDC referenceHdc, Rect& frameRect, MetafileFrameUnit frameUnit, EmfType type, WCHAR* description)<br />
<br />
Creates a Metafile object for recording to an IStream interface.<br />

Does anyone know how this is possible? Perhaps some atl / com code? I need this for a Visual C++ 6.0 Mfc app.

Thanx a bunch! I really appreciate your help Smile | :)

Cheers,

Hi ya all!
The following code i supposed to create a window inside another window.

m_Page.CreateEx(WS_EX_LEFT | WS_EX_TOPMOST,
AfxRegisterWndClass(CS_CLASSDC),
_T(""), WS_VISIBLE | WS_CHILD, rcClient.left, rcClient.top,
rcClient.Width(), rcClient.Height(), m_hWnd, NULL);

The window is created at program start (I'm able to paint in it), but at close I get;
"Unhandled exception at 0x77f7f570 in kalender.exe: User breakpoint."
Which point to;
"77F7F570 int 3" in Disassembly

If the mousepointer is in this window at program start it show a hourglass, until the pointer is moved outside this window.

Thankfull for all your help

LanguageID to String

Hi There.

I have a very easy question Smile | :)

Do there exists any API function or so, in MFC/Windows that can return with a language string, if it receives a language ID? For instance:

LanguageID2String(0x09) will then return "English"

I know that there must be a function like this, but I can't find it. Can you help me? Smile | :)

Thanks in advance,

Best Regards

IMultiLanguage *pML;
HRESULT hr = CoCreateInstance(CLSID_CMultiLanguage, NULL, CLSCTX_ALL, IID_IMultiLanguage, (void**) &pML);
hr = pML->GetRfc1766Info(0x09, &info);

You may enumerate all locales with:

IMultiLanguage *pML;
HRESULT hr = CoCreateInstance(CLSID_CMultiLanguage, NULL, CLSCTX_ALL, IID_IMultiLanguage, (void**) &pML);
IEnumRfc1766 *pEnumerator;
hr = pML->EnumRfc1766(&pEnumerator);
RFC1766INFO info;
ULONG nRet;
while (SUCCEEDED(hr))
{
    hr = pEnumerator->Next(1, &info, &nRet);
    if (SUCCEEDED(hr))
    {
        CString str(info.wszLocaleName);
        TRACE(str + "\n");
    }
}

Hope that helps.

If you have IE 5.5 or later, you may use HRESULT LcidToRfc1766(LCID locale, LPTSTR pszRfc1766, int nChar); The previously posted example should work with IE 4.0 according to MSDN.

Using an ActiveX control in VC++

2-May-02 5:29

There are always simpler ways to do things Blush | :O

Either one of

::GetLocaleInfo(0x09, LOCALE_SENGLANGUAGE, szBuf, 256);
::GetLocaleInfo(0x09, LOCALE_SLANGUAGE, szBuf, 256);

will do, depending on what info you need. I've had this thing on my mind all day, so I had to investigate it further. I knew there must be something for this in the windows API. Well, it wasn't harder than this Smile | :)

When trying to use my ActiveX control in Visual C++, I noticed that when inserting the control in the dialog the control will not be created which causes the m_hWnd to be NULL which causes problems in my control behavior at design time. What shall I do to overcome this problem? Any ideas?

I´m having problems getting the my process handle, using GetCurrentProcess() I always
get 0xfffffff... back. I need to get my own process handle to pass on to a watchdog process to monitor, has anyone any idea how to get to grips with this problem ?
ps, I´m using ATL/WTL and API NO MFC

The return value is a pseudo handle , to get the real handle use GetCurrentProcess() with DuplicateHandle() or call to OpenProcess()

Thanks, I used the following code
HANDLE hHandle;
DuplicateHandle(GetCurrentProcess(), GetCurrentProcess(), GetCurrentProcess(), &hHandle, PROCESS_ALL_ACCESS | STANDARD_RIGHTS_REQUIRED |THREAD_ALL_ACCESS, FALSE,NULL);
CloseHandle(hHandle);

That worked...

The 0xff thing is correct as in the doc however u may want to use the PID instead i.e. GetCurrentProcessId()

Until the process terminates, the process identifier uniquely identifies the process throughout the system
