I've never programmed in Tcl, could you give me an idea of how this would be done?

Thanks

When you create your application I think at 4th step you can set it in checkbox.

Why the drawed rectangle disappeared

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

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

vmf30-Apr-02 2:07

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?

radio button text caption

Does anybody knows how to change text label (caption) of the radio buttons ?
Good sample will be very nice to see .. !

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.
