Suppose you have a radio button (id is IDC_RADIO1) and another radio button (IDC_RADIO2). You could code something like this:

void CMyTestDlg::ChangeCaption()
{
 CWnd* pWnd = GetDlgItem(IDC_RADIO1);
 pWnd->SetWindowText("Choice_001");

 pWnd = GetDlgItem(IDC_RADIO2);
 pWnd->SetWindowText("Choice_002");
}

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,

Please help! -Window creation

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.

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 | :)

Using an ActiveX control in VC++

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?

Process Handle

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

Re: Process Handle

That´s true, but as far as I Know (read) you can not terminate or kill a process with the PricossID, just with the Process handle.
But any way, I ´ve solved that problem, know I have to change the Token on NT/XP/2000 system to Terminate/Kill the process, and Shutdown or reboot, and the MSDN is not very helpfull at all Frown | :(

Getting control HWND to active Window from another program

29-Apr-02 23:11

I have a program (like a virtual keypad) which I wpould like to inject typed things into another process. What I have works if the program that gets it is the main window (like notepad etc). However, if I want to send things to a control like edit box INSIDE the window, I know that the window gets the message but the edit box does not.

This is due to the fact I get the HWND to the window of the target windo as

HWND wnd =::GetForegroundWindow()

Thus I tried to do this:

CWnd* pWnd = FromHandle(wnd);
CWnd* pFoc = pWnd->GetFocus();

I then use pFoc->m_hWnd in the AttachTHreadINput call

What is wrong here. I get some can not read from loc ??? error. What would I need to do to get the HWND to the actual control inside the window that has the focus FROM another program?

THanks for any advise.

Setup a Printer Setup Dialog

29-Apr-02 23:05

Before I setup the Printer Setup dialog I wanted to set the paper size and orientation ect.

What I did was:

CPrintDialog PDlg(TRUE);
GlobalAlloc(GMEM_MEVABLE, sizeof(DEVMODE));
DEVMODE* pDevMode = (DEVMODE*) GlobalLock(PDlg.m_pd.hDevMode);
pDevMode-> ...
...
GlobalUnlock(PDlg.m_pd.hDevMode);
PDlg.DoModal();

According to MSDN this should be enough to initialize things before the call to DoModal, right?

Thanks for any suggestions.

version control for Visual C++

29-Apr-02 22:30

I'm interested to know what version control ppl use at work. I'm currently evaluating visual sourcesafe with sourceoffsite for distributed team collaboration on code and also cvs on a linux machine with windows gui clients. One is free and the other is not but has anyone had any experiences with both or use something else?

We use SourceSafe and SourceOffsite here. biut I'm afraid I've got no experience of CVS.

This topic has been discussed pretty extensively in the Lounge, so I'd suggest a quick trail through the posts (don't worry, there's only 77,000 of them Roll eyes | :rolleyes:

) would be a good starting point.

Just try setting the filter to "SourceSafe" or "version control" and you'll find plenty of information. Smile | :)

We have used WinCVS at work and found that on many occations it 'Lied' to us about diffs in files.

We also us Source Safe on projects where we use Visual Studio as it is conviently intergrated. A warning however if the SS database is on a UNIX server, be sure that the file system which contains the 'sepository' is not subject to quotas. If a user overruns the soft quota during the checkin process, it screws up the repository because the file will be integrated and the history update may not happen. This happened a number of times on a previous project I worked on and now I have insisted that source code is free of quotas, because we know that no matter which system you use the repository will only grow and not shrink.

Happy programming!!

Question of the year: what does #pragma start_map_region do?

29-Apr-02 22:18

I have imported office 97 (or maybe XP), no dll hell any more, now it is called com hell;

#import "D:\Microsoft Office.97\Office\Mso97.dll"
#import "c:\Program files\Common Files\Microsoft Shared\VBA\VBE.DLL"
#import "C:\Program Files\Common Files\Microsoft Shared\VBA\VBEEXT1.OLB"
#import "D:\Microsoft Office.97\Office\MSWORD8.OLB"

As i would like to support different office versions, i need "a bit" changed headers, so there wouldnt be any namespace conflict between different versions of imported librarys.

After checking tlh, i have encountered on #pragma start_map_region. What does it do?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
