What are the header files you included?

I've only use standard header files.

Actually I can solve it just passing the CString to the getText function as follows.

CString getText(const CString rtf)

But why I can't pass the string as reference.

Also, I want to find the '\pard' string of the full string and replace it with '['. I tried this,

rtf.Replace(_T("\\pard"), _T("["));

It gives another error,

'ATL::CStringT<basetype,stringtraits>::Replace' : 2 overloads have no legal conversion for 'this' pointer<br />
        with<br />
        [<br />
            BaseType=char,<br />
            StringTraits=StrTraitMFC_DLL<char><br />
        ]</char></basetype,stringtraits>

What is mean, I've try this before search the string(ie: before the for loop)

I appreciate your help all the time...

In other words?
I made a little test (console without MFC) project, including atlstr.h to use non-MFC string and I had no compilation issues both for

void getText(CString &str)
{
	...
}

and

...
CString s;
s = _T("\\pardHi");
s.Replace(_T("\\pard"), _T("["));
...

the latter setting correctly s = "[Hi"

Thanks for the replay.

Are you sure this is correct. Gives the compilation error on '_' identifier is not found.

Yes, provided you include the Generic-Text Mappings header tchar.h.

Ok, I got the points. I've miss the text mappings. Smile | :)

Actually what I want to do is replace '\pard' with '[' from the whole string, that is of the rtf. That is why I use rtf.Replace(_T("\\pard"), _T("["));

If you can send me your mail address. If you can please check my code and let me know where I'm going wrong.

This is working for me, why don't you use non-MFC CString ?

I need to write a voice over ip module applied between 2 hosts for a local network using vc++? Is there anybody can provide me some information or guide or sample on it? I need to solve it within 2 weeks and i don't have any idea yet. In fact i am not really clear on how VoIP function as well.

Then the first thing you have to do is to search for info about the VoIP and read. If you don't even understand what you will try to do... it will be pretty difficult for you to programm it.

I need help in initialization list/constructor in abstraction

Hi All
I need help in initialization list/constructor in abstraction

I have abstract base class -
class ICloth
{
ICloth();
...........

}

class CMyCloth:public ICloth
{
CMyCloth(EColor color, ESize size,EStatus status,EType type,EQuality
quality);
...........

}

class CHighTechCloth:public CMyCloth
{
public:
CHighTechCloth();
...................

}

/////
now in main I try to create CHighTechCloth object, what do I do wrong?

CHighTechCloth* pMyNewCloth = new
CHighTechCloth():ICloth(ICloth::EC_RED,
ICloth::CS_SMALL,
ICloth::CST_NEWCLOTH,
ICloth::CT_EYEGLASSES,
ICloth::EQ_LOW)

Re: I need help in initialization list/constructor in abstraction

CPallini11-Dec-07 0:54

You simply cannot do that.
You have either to provide a default constructor for class CMyCloth (and you've lost the 'per instance members initialization feature')
or a compliant (to class CMyCloth's one) constructor for CHighTechCloth class, for instance:

class CHighTechCloth:public CMyCloth 
{
public:
  CHighTechCloth(EColor color,
                 ESize size,
                 EStatus status,
                 EType type,
                 EQuality quality): 
                 CMyCloth( color, size, status, type, quality)
                 {}
...
}

BTW compiler error messages usually give meaningful hints.

Hello,
I have a variable called hwnd which stores a handle to one of the windows created by other process. Is there any way to get notified when the title of the window identified by hwnd changes? Can this be done by hooks or without them? If yes how?
thanks in advance

I think with hook it might be possible. Install a message hook and look for the WM_SETTEXT message.

I have to convert that value into double .

My code is

CString svalue;
