Re: MFC - how to get an edit box text from another dialog?? (Constructor)

From class wizard, maindialog's member variables I added a member variable to the editbox which gets the editbox's value and then as you said, I equalize each variables but than it returns nothing from main dialog ??? Frown | :(

You could use GetDlgItemText()[^] and its counterpart SetDlgItemText().

I did it as Mahdu replied and by your hint... like

C++

void mainform::OnBnClickedButton2()
{
			GetDlgItemText(IDC_EDIT1,newform.strtext);
}

BOOL newform::OnInitDialog()
{
			SetDlgItemText(IDC_EDIT1, strtext);
}

THANKS TO YOU ALL FOR REPLIES PEOPLE!!! YOU ARE GREAT... Smile | :)

How about something like:

CMainDlg::OnButtonClick()
{
    CString strText;
    m_edit.GetWindowText(strText);
 
    CSecondDlg dlg;
    dlg.setData(strText);
 
    dlg.DoModal();
}
 
CSecondDlg::setData( LPCTSTR lpszText )
{
    m_strText = lpszText;
}
 
CSecondDlg:OnInitDialog()
{
    m_edit.SetWindowText(m_strText);
}

I'm a big fan of weak coupling, so tying these two dialogs together like this would not be my first choice. I would opt for a "data transfer" or "liaison" class instead. This is a one-instance class where you would put all of your shared data.

By the way, you can just explain this :

C++

CFileDialog *pOpenDlg=new CFileDialog(FALSE,".txt",NULL,OFN_OVERWRITEPROMPT,"Text Files (*.txt)|*.txt|All Files(*.*)|*.*||");

please help me

The current list should be in file WinNT.h; search for keyword LANG_NEUTRAL. See also second response.

Further research suggests you should use one of the locale support functions such as EnumSystemLocalesEx()[^].

Hi,

I believe Microsoft discourages using the MLANG interface. At least that's what it use to say on MSDN. However I looked just now and could not find the do-not-use disclaimer. With that being said... A few years ago I managed to figure out how to use some of the vaguely documented interfaces. Here is what I use to enumerate available locales:

C++

HRESULT hr = CoInitialize(NULL);
if(SUCCEEDED(hr))
{
	IMultiLanguage * pml;
	hr = CoCreateInstance(CLSID_CMultiLanguage,NULL,CLSCTX_ALL,IID_IMultiLanguage,(void**)&pml);
	if(SUCCEEDED(hr))
	{
		RFC1766INFO info;
		ULONG num;
		IEnumRfc1766 *rfc1766;
		hr = pml->EnumRfc1766(&rfc1766);
		if(SUCCEEDED(hr))
		{
			while(S_OK == rfc1766->Next(1,&info,&num)) 
			{
				WORD wLangID = LANGIDFROMLCID(info.lcid);
				//You can also get the locale name such as 'English' or 'Chinese' at info.wszLocaleName[32]
			}
		}
	}
	pml->Release();
}
CoUninitialize();

Hi,

Modify the code zon_cpp gave you and use something like this in the CDDS_ITEMPREPAINT case:

C++

HFONT hOldFont = (HFONT)SelectObject(pLVCD>hdc, m_Font);
// Draw your text... you can get the row/column text using GetItemText()
// You can get the row# using pLVCD->nmcd.dwItemSpec
// And get the column# using pLVCD->iSubItem
// You can tell the CListCtrl *not* to draw over what you just did by setting *pResult = CDRF_SKIPDEFAULT;
SelectObject(pLVCD>hdc, hOldFont);

In your header add:

C++

CFont m_Font;

In your dialog constructor add something like:

C++

m_Font.CreateFont(13,0,0,0,FW_NORMAL,0,0,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,ANTIALIASED_QUALITY,DEFAULT_PITCH | FF_DONTCARE,_T("MS Shell Dlg 2"));

I'm trying to read text from a text file. I look for in msdn how to read and write in text file, and I found this:
http://msdn.microsoft.com/es-es/library/6337eske.aspx[^]

I made this funtion to read from my text file:

void CDlgResultados::loadFromFile(void)
{
	CString path= GetUserHomeDir() + _T("\\Documents\\file.txt");
	
	TCHAR	szBuffer[256]; 
	UINT    nActual = 0; 
	CFile	myFile;

	if ( myFile.Open(path, CFile::modeCreate |   
	   CFile::modeRead ) )
	{
	   myFile.Write( szBuffer, sizeof( szBuffer ) ); 
	   myFile.Flush();
	   myFile.Seek( 0, CFile::begin );
	   nActual = myFile.Read( szBuffer, sizeof( szBuffer ) ); 
	}
	m_Edit.SetWindowTextW(szBuffer);
}

But when I run the app and I press the button to read the file, I get a error that it said:
You dont have acces to this file.

What is the actual value of the string in your path variable, at the time you try to create the file?
