C / C++ / MFC

Hi,

I'm having difficulties using CString's LoadString under VC++ 8.0. I'm not sure what to make of it. I'm attempting to load a string from resources and getting back an incomplete string, e.g. "This application is registered to %1 %2For use on the computer named %3 only." and getting back, "This application is registered to %1????". The '?' are inserted into the string. I'm a total newbee to VC++ 8.0.

It seems to be random, cause loading strings from the resource seems to work correctly in the instances above the lines of code before calling the last LoadString.

e.g.
BOOL CAboutDlg::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here
CString cs0, cs1, cs2, cs3, cs4;

DWORD dwSizeUserName, dwSizeComputerName, dwError;

char szUserName[MAX_COMPUTERNAME_LENGTH + 1];
char szComputerName[MAX_COMPUTERNAME_LENGTH + 1];

dwSizeUserName = MAX_COMPUTERNAME_LENGTH + 1;
dwSizeComputerName = MAX_COMPUTERNAME_LENGTH + 1;

szUserName[0]=0;
szComputerName[0]=0;

m_nAppIcon.SetIcon(::LoadIcon(theApp.m_hInstance, MAKEINTRESOURCE(IDR_MAINFRAME)) );

cs0.Empty();
cs0.LoadString(AFX_IDS_APP_TITLE);

AfxSetWindowText(::GetDlgItem(this->m_hWnd, IDC_STATICTEXTAPPNAME), cs0);

cs0.Empty();
cs1.Empty();
cs2.Empty();
cs3.Empty();
cs4.Empty();

cs1.LoadString(IDS_STRABOUTAPPINFO);
// IDS_STRABOUTAPPINFO =
// File Version: %s\nProduct Version: %s\nApplication Info: %s\n\n%s by
// %s. All Rights Reserved.

cs2.LoadString(IDS_FILEINFOCOMMENTS);
// IDS_FILEINFOCOMMENTS = Comments

cs3.LoadString(IDS_FILEINFOLEGALCOPYRIGHT);
// IDS_FILEINFOLEGALCOPYRIGHT = LegalCopyRight

cs4.LoadString(IDS_FILEINFOCOMPANYNAME);
// IDS_FILEINFOCOMPANYNAME = CompanyName

cs0.Format( cs1,
CAppUtilitylFunctions::GetFileVersionX(),
CAppUtilitylFunctions::GetProductVersionX(),
CAppUtilitylFunctions::GetVersionInfo(NULL, cs2),
CAppUtilitylFunctions::GetVersionInfo(NULL, cs3),
CAppUtilitylFunctions::GetVersionInfo(NULL, cs4));

AfxSetWindowText(::GetDlgItem(this->m_hWnd, IDC_STATICTEXT1), cs0);

if( !(::GetUserName(szUserName, &dwSizeUserName)) )
{
dwError = GetLastError ();
}
if( !(::GetComputerName(szComputerName, &dwSizeComputerName)) )
{
dwError = GetLastError ();
}
else
{
cs0.Empty();
cs1.Empty();

// THIS LOAD FAILS TO LOAD ALL OF THE STRING IN THE RESOURCE
cs1.LoadString(IDS_ABOUTAPPINFO);
// IDS_ABOUTAPPINFO =
// This application is registered to %1 %2For use on the computer
// named %3 only.

cs0.FormatMessage( cs1,
szUserName,
"\n",
szComputerName);

AfxSetWindowText(::GetDlgItem(this->m_hWnd, IDC_STATICTEXT2), cs0);
}

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}

Cry | :((

Can someone shed some light on this for me? I'm thinking that it must have something to do with project settings....

Thanks!

Can you check its return value ? Its BOOL.
To narrow down the problem , can you check value in cs1, by showing it in message box?

Hi,

Thanks for the reply. using bool bRet, e.g. bRet = cs1.LoadString(IDS_ABOUTAPPINFO); The return value is 'true'. The string returned however is truncated and contains, cs1 "This application is registered to %?????" ATL::CStringT<char,StrTraitMFC_DLL<char,ATL::ChTraitsCRT<char> > > as reported in the VC++ 8.0 IDE 'Autos' tab.

If I use a line like 'CString cs5(MAKEINTRESOURCE(IDS_ABOUTAPPINFO));' cs5 is equal to the same malformed string as if I loaded it from the resource string table above.

Do I have to specify something in my project settings ? Confused | :confused:

Or is something getting screwed up in the string table.... OMG | :OMG:

Thanks!

Problem seems to be with format specifiers you have mentioned. Can you see same problem with strings without format specifiers(%).

Hi,

Thanks for your reply. Actually, if I move the string loading to the top of the function, it works correctly. The entire string is loaded. I've tried several locations to narrow down where the load string gets truncated, but have not found the problem.

This is driving me mad, as I know something else is wrong, and it is not LoadString() per se, but have not been able to find the problem.

Thanks!

Hi,

I've changed the previous Format to FormatMessage and the specifiers to %1, %2, %3, etc. and all seems to be fine with the string loading as it should. It is hard for me to believe that using CString Format could screw up memory on an unrelated LoadString.... Hmmm.

Any body have any ideas on this?

Please help....

Thanks!

There is difference bet'n Format and FormatMessage, the way format specifiers are mentioned.
::FormatMessage documentation in MSDN can through some light on it.

Actually , instead of using same variable(using Empty), try using different variables.(this is just wild try).

You should read the full page, in particular the content of the exams. ASP.NET, VB.NET, C#.NET... Think of .NET as an extension to all of the programing languages.

Hi,
I want to get the active childframe in a MDI application when I am in the ViewClass. I need a pointer of CWnd to use it as parameter for MDIActivate.

Can someone tell me how to get it?

Hello

1- CWnd::GetActiveWindow(). Doesn't it work with you?
2- Or even better CWnd::GetTopWindow().

Regards

Hi Nader,
thanks for your reply. So I got the window, but I can't use it for what I want to do.
In my MDI application I open new childframes automaticly but I want to stay the actually childframe in front.
I tried this way:

CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
// Get the active MDI child window.
CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame();

// Get the active view attached to the active MDI child window.
CErgebnislisteView *pView = (CErgebnislisteView *) pChild->GetActiveView();

//Open new childframes
for(i=0; i< arrVerz.GetSize(); i++)
{
            //set some variables and open it with the next line
    theApp.OnOldTurnier();
}

    //activate the old childframe

    pChild->SetActiveView(pView);      //nothing happens

Do you have an idea how do do it?
yummi
