using the '€'-sign with std::wofstream doesn't work - C / C++ / MFC Discussion Boards

Hi!
I know this may looks a little funny! But when I use CDialog::EndDialog to terminate my dialog based app, the main window (dialog) disapears well, but when looking at Task Manager, I found it already running!
Can U help me PLS?

Hi,

If you have other threads running, the app will wait for them to terminate, unless they
are set to be background threads.

Thanks 4 Ur reply!

I've not made any thread myself;
Is it possible for MFC classes to create threads by themselves? (Specially I used CRecordset frequently in my app!)

Thanks 4 Ur attention!

I don't know, it could be. If so, it must be documented, and the doc should tell you what
to do about it, say call Close(), Stop() or whatever is appropriate.

EndDialog() may be the wrong method for shutting down your app.

It depends on how and where you create the main dialog. Is it modal or modeless?
Where in the code do you create it?

CDialog::EndDialog is for modal dialogs. That means your main dialog needs to be created modal.
When control returns from the modal dialog, your app needs to exit. It should be something like this:

BOOL CMyApp::InitInstance()
{
    // do app initialization here!
    // ...


    CMyMainDlg dlg;
    m_pMainWnd = &dlg;
    INT_PTR nResponse = dlg.DoModal();
    if (nResponse == IDOK)
    {
        // TODO: Place code here to handle when the dialog is
        //  dismissed with OK
    }
    else if (nResponse == IDCANCEL)
    {
        // TODO: Place code here to handle when the dialog is
        //  dismissed with Cancel
    }

    // Since the dialog has been closed, return FALSE so that we exit the
    //  application, rather than start the application's message pump.
    return FALSE;
}

If you return TRUE from InitInstance(), that would cause the behavior you're seeing, since the app
would still be running but the dialog would be gone.

hi
i need to write the € sign (currency in europe) to a file.

i have some text in a std::wstring which includes a €-sign. if i put the text in the stream any following letter after the euro sign won't receive the output file.

i tried to solve the problem by replacing the sing with the unicode sequence, but with no positivie result

<br />
<br />
#include "stdafx.h"<br />
#include <fstream><br />
<br />
<br />
int _tmain(int argc, _TCHAR* argv[])<br />
{<br />
	std::wstring s = L"Hello World, i own 20 \u20AC hurray!";<br />
	std::wofstream out(L"C:/euro.dat", std::ios::binary);<br />
	out<<s.c_str();<br />
	return 0;<br />
}<br />
</fstream>

my outfile euro.dat contains for this example "Hello World, i own 20 " anything after is missing.

i figured out that if i use std::string it works(why ever), but i would prefer a soloution that supports std::wstring. anyone has a idea how to make things running with wstring ?

See here [^].

Hi all,

I want to pass a CString parameter through ShellExecute() api to my exe..

I am doing this using this code:-

CString CurrentPath = _T("C:\\test\\test.ini");
ShellExecute(NULL,_T("open"),CurrentPath,NULL,NULL,SW_SHOW);

My problem is i don't know how to access this parameter in my exe.

Can anybody tell me how to do so??

Thanks in advance

I see no exe in the above code.

sorry i posted wrong code

CString CurrentPath = _T("C:\\test.exe");
CString para = _T("c:\\test.ini");
ShellExecute(NULL,_T("open"),CurrentPath,para ,NULL,SW_SHOW);

what i want is i want to access para value in my test.exe code

Hi,

it depends on language and compiler.
Most often you can get the command line as a string and/or the command line parts as a
string array; look for:
- the (optional) arguments of your main or WinMain function;
- a library function such as GetCommandLine.

BTW: When an array is returned, most likely the first element is the path of the EXE itself.

Hi there,

I am currently now beginning to learn C++. As i am new i will keep editing the program and do compilation for quite a number of times. It seems that every time i do it for more than 5 to 6 times the program will start to hang and i cannot compile nor stopping the compilation. Kindly assist me on this matter, really appreciate it.

Regards

Do you mean Visual Studio IDE hangs? Then you probably have to install it again.

Hi,

The Subject explains my prob, i wanna to put my formview in the middle of my screen

I use the SetWindowPos as below:

<br />
	CRect Rect;<br />
    GetParentFrame()->GetWindowRect(&Rect);<br />
    GetParentFrame()->SetWindowPos( NULL,0,0,900 ,200 ,SWP_NOMOVE | SWP_NOZORDER);  <br />
    SIZE size;<br />
    size.cx=Rect.Width()/2;<br />
    size.cy=Rect.Height()/2;<br />
    SetScaleToFitSize(size); <br />

in other way i wanna change the x, and the y ( i don't matter about the cx & cy) coz they depend on other vars but what ever the cx & cy values are, i wanna havr the form in the center of my screen.

PS: may be i should use some funct like GetWindHeight() or sth else Roll eyes | :rolleyes:

centerwindow()

Like That??

I found the sol thx Wink | ;)

"The Ultimate Limit Is Only Your Imagination."

Is it safe to use OnNewWindow2 on multithread ?
For example, one thread's WebBrowser fire NewWindow2 and let another
thread's application take the Dispatch pointer ?
AthreadWebBrowser::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)
{
Cancel = FALSE;
HRESULT hr;
CoInitializeEx(NULL,COINIT_MULTITHREADED);
LPSTREAM pStream = NULL;
hr = ::CoMarshalInterThreadInterfaceInStream(IID_IDispatch,*ppDisp,&pStream);
if(hr != S_OK)
{
AfxMessageBox("couldn't get interface");
}
}
but it's failer
