Hi all,
I'm testing some code and just created a simple mfc console app (using the wizard) in VC6.
I did a first build after project creation, without any change, and it worked ok. Then I've gone to the project's settings and in the C/C++ tab, in the general category, I added _UNICODE and removed _MCBS from the preprocessor definitions. That line now has the following:
_DEBUG,WIN32,_CONSOLE,_UNICODE,_AFXDLL
Now the problem is that after making a full rebuild, the output of the program is wrong: instead of displaying the "Hello..." string it displays the address of the text. 
If I remove the _UNICODE define, all is ok. I've been testing and found out the following:
cout << "Test" << endl;
outputs: Test
cout << L"Test" << endl;
outputs: 0041401C
cout << _T("Test") << endl;
outputs: 0041401C
I thought that cout was unicode compliant...
What the ... am I doing wrong?
TIA

yes, cout accepts only byte stream.
once u compile as unicode ur "Test" is defined as multi stream and is not displayed correctly.
greatest thing is to do wot others think you cant

Thanks for the tip...
So, the best way to deal with it is just to use _tprintf() and similar and forget about cout, right? This way I don't need to worry if I'm using Unicode or not.
Not a big problem, as this is just a test application.
But, just for curiosity, is there nothing in stl that can output unicode strings?

'cout' is char, 'wcout' is wide.
_UNICODE is a Windows and MS thing, so it won't change std::cout into std::wcout, or std::string into std::wstring.
So you could use the preprocessor to do it for you,
#if defined ( _UNICODE )
#define COUT wcout
#else
#define COUT cout
#endif
cout << "Test" << endl ;
wcout << L"Test" << endl ;
COUT << _T"Test" << endl ;
which should produce three 'Test's regardless of how _UNICODE is defined.

I didn't knew about wcout...
(in fact, the only times I use cout is in small console projects to be able to quick-test some code)
Thanks for the info.

For those who are still using VS6, it appears that Service Pack 6 was released yesterday. I hope this is not a repost - if so I'll delete this message.

Really? The last I'd heard, about 6 months ago, was that MS had no plans to release any further service packs! This is good news - thanks!

Hi All,
I have a CMDIChildWnd application where each child window loads a CFormView.FormView contains some edit controls,comboxes etc.(note:edit boxes,comboboxes are standard MFC controls)
when i double click on any edit box to select the contents,the focus is always going to first control in the tab order.I dont have OnLButtonDbClick() method in my code.
Please some one tell me what might may be the possible reason.
Thanks in advance...

I'm implementing my own version of the Explorer 'New' menu.
'Create Shortcut' and 'Create Briefcase' are both stored in the registry as REG_EXPAND_SZ strings.
I've used ExpandEnvironmentStrings to translate things like %SystemRoot% to c:\winnt\system32.
My problem is the %1, %2 parameters.
I've succesfully ran the 'create shortcut' command supplying the directory under-which I want the shortcut to be created in instead of %1. When I try to play the same trick on the Briefcase item it does nothing.
What does the !d! in :
%SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\syncui.dll,Briefcase_Create %2!d! %1 translate to ? What are the rules for %1 %2 and %x ?
Is there a 'normal' way to execute this commands, without hacks ?
Thanks

I have created a dll file and 2 lib files using VC++6.0. I have a tester application which test the functions in these dll and lib files. Now I want to debug my project using vc7.0. I have the .NET framework 1.1 installed(I don't have the MDE). How can I compile the project from the command prompt(cl.exe)? Is there any article which gives me information on this.
I have seen the options given in MSDN. Can anyone give me some sample commands. I have tried certain options, but it gives me an error, undeclared, in Program Files\Visual Studio\vc98\Include\Utility.
Can anyone help me pls..
Thanks

Hi Friends,
I have some quries regarding the Class Memory layouts.
Please consider the following questions for each example
question 1: Class Memory layout along with size
question 2: Number of vatables and there contents.
question 3: Number of Vptrs.
------------------------------------------------------------
Examples:
class Normal{
}; //Layout /Size??
------------------------------------------------------------
class Base{
public :
void Function(void){
}
};
class Derived :public Base{
void Function(void){
}
}; //How Function Overriding Works? Depends Upon Pointer type? How?
//Like Base class pointer will call base class functions? and derive class pointer will call derived class functions?
------------------------------------------------------------
class Normal{
public:
virtual void Function(void){
}
}; //Layout of VTABLE along with VPTR
------------------------------------------------------------
class Base{
public :
virtual void Function(void){
}
};
class Derived :public Base{
void Function(void){
}
}; // How many vtables and vptrs? Where? What will be the exact layout?
------------------------------------------------------------
class Base{
public :
virtual void Function(void){
}
};
class Derived :public Base{
virtual void Function(void){
}
}; // Now if I declared virtual function in derived class then?
//what will be layout along with vptr?
------------------------------------------------------------
class Base{
public :
virtual void Function(void){
}
};
class Derived :public Base{
void Function(void){
}
virtual void Function1(void){
}
}; // Now if I declared some other virtual function in derived class then?
//what will be layout along with vptr?
------------------------------------------------------------
class Base{
public :
virtual void Function(void){
}
};
class Base2{
public :
virtual void Function1(void){
}
};
class Derived :public Base,public Base2{
};// Here What if I have 2 base classes along with virtual function ?
------------------------------------------------------------
class Base{
public :
virtual void Function(void){
}
};
class Base2{
public :
virtual void Function1(void){
}
};
class Derived :public Base,public Base2{
virtual void Function2(void){
}
};// Here What if I have 2 base classes along with virtual function also my derived
//class has it's own virtual function so How many vptrs/vtables?

Read the book : "Inside C++ Object Model", by Stanley Lippman, and you will get a clear picture about all the three questions of yours.

Very often when enabling the flag OFN_ALLOWMULTISELECT allows one to multiple select a number of files in a current folder.
However there's a limit where one can select a number of files and thereafter... the dialog hangs on you. I would like to find out a more economical method of dynamically allocating memory for this kind of situation. I derived the CFileDialog to a new class and gave it a new variable TCHAR* m_varString;
I override the OnFolderChange() putting some code that shows below..
However it's not efficient and it seems to show rubbish every time I reopen the CFileDialog. After certain time a memory violation occurred. It all seemed strange to me. Perhaps I'm heading the wrong way. Can someone please advise me what I shoud correct? Thanks...
void CFileDialogEx::OnFolderChange()
{
// TODO: Add your specialized code here and/or call the base class
CString cstrFolderPath = GetFolderPath();
DWORD dwBufCount = cstrFolderPath.GetLength();
cstrFolderPath += _T("\\*.*");
CFileFind ff;
BOOL bFound = ff.FindFile( cstrFolderPath );
while ( bFound )
{
bFound = ff.FindNextFile();
if ( !ff.IsDirectory() )
dwBufCount += ( ff.GetFilePath().GetLength() );
}
dwBufCount += 1;
ff.Close();
delete m_pszVar;
m_pszVar = (TCHAR*) new TCHAR[dwBufCount];
m_pszVar[0] = _T('\0');
m_pOFN->lpstrFile = m_pszVar;
m_pOFN->nMaxFile = dwBufCount;
CFileDialog::OnFolderChange();
}

If you can wade through the VB code here[^] you can probably bang out a nice, efficient C++ utility to convert PCM to .wav.

You can read up on the file format and do it yourself, find an existing library from Google or elsewhere, or investigate the 'Multimedia IO' functions such as 'mmioOpen' in MSDN. The DirectSound part of the DirectX development kit contains some C++ helper classes, such as 'CWaveFile' that wrap mmio functions helpfully and are probably the quickest approach to a correct result.
You will have to create a wav file, write the right sound format (bits, samples, channels, compressed/not etc) then, assuming that the samples are compatible, you can just write them out.
