In a dialog based application, I draw a rectangle with
CRectTracker. But when i close a sub-window, the part of the drawed rectangle (the part of the covered) also disappeared. Why ?

The following is my code:

BOOL CMYDlg::PreTranslateMessage(MSG* pMsg)
{
switch (pMsg->message)
{
case WM_LBUTTONDOWN:
{
if (pMsg->hwnd == GetSafeHwnd())
{
CPoint pt;
pt.x = GET_X_LPARAM(pMsg->lParam);
pt.y = GET_Y_LPARAM(pMsg->lParam);

if(GetAsyncKeyState(VK_SHIFT) < 0)
{
CRect re(pt, pt);
CRectTracker rt(re, CRectTracker::solidLine | CRectTracker::resizeOutside);
if (rt.TrackRubberBand(this, pt, TRUE))
{
CDC* pDC = GetDC();
rt.Draw(pDC);

CSetRect dlg;
dlg.m_rectleft = rt.m_rect.left;
dlg.m_rectright = rt.m_rect.right;
dlg.m_recttop = rt.m_rect.top;
dlg.m_rectbottom = rt.m_rect.bottom;
if(dlg.DoModal() == IDOK)
{
OnSaveRectInfo(dlg.m_rectleft, dlg.m_rectright, dlg.m_recttop,dlg.m_rectbottom);
}
}
return TRUE;
}
break;
default: break;
}
return CDialog::PreTranslateMessage(pMsg);
}

IMHO, you are doing far too much work in PreTranslateMessage. if you want to handle a mouse down event, override the appropriate function (OnButtonDown, i think); if you want to paint something, override OnPaint. PreTranslateMessage isn't supposed to be used as a place to do Win32-style message loop programming.

profiling with vc++

I'm trying to get the profiler working ( again ! )on my project but as usual with the profiler, it does not work very well ...

any idea why I get this error ?

PREP : fatal error PRF1011: cannot open file c:\project\my_project\full_profile_release\my_project.pbo

and from MSDN, prf1011 doesn't give more info ...

who/what is supposed to generate that file ? isn't supposed to be automatic when
started from the IDE ?

I also tried using the shell ( cmd ) to run the profile ( with the ftime.bat ) but , bummer, it doesn't work ....

any ideas

Thanks.

Max.

Have you enabled generating the map file on your release build?

If i remember right, the initial PREP phase requires the .map files to generate the .pbi which PROFILE processes to create the .pbo files. Finally, PREP is run again with the /M switch to consolidate all the .pbo files into a single .pbt file.

I've played with the command line version a while ago & this is the template FTIME.bat that i used to get it to work.

PREP /OM /FT /EXC nafxcwd.lib /INC File1.cpp /INC File2.cpp MyApp
if errorlevel == 1 goto done 
PROFILE MyApp 
if errorlevel == 1 goto done 
PREP /M MyApp
if errorlevel == 1 goto done 
PLIST /ST /T MyApp >MyApp.txt

Toolbar positioning problem

Hi all

In my application I'm having two toolbars.
When I create second one, framework inserts it in new row, but I want it
to be placed on the right of the first one.
I tried to use DockControlBar() providing lpRect parameter, but it makes no difference.
Of course I can drag second toolbar with mouse, but I don't know how to do this
programatically.

Thx in advance

Split Table during PowerPoint Automation

30-Apr-02 2:07

I am trying to automate an application which contains tabular data. This data when sent to a Word application manages to push the table onto the next page, but not in PowerPoint. I end up having a huge table which cannot be viewed entirely in a single slide.
Is there any way to make the automation controller smart enough to split the table during export?
Does anyone have any other solution?

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");
}

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,

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 | :)

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

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