I want to initilize value of form. Usually in dialog we add in OnInitDialog(), what about in CFormView?
Thanks.

RTF file

Hi all,

Now I've start to work on another work. I'm looking to read a RTF(Rich Text Format) file. Here is a simple *.rtf file content, which is open using a notepad.

<br />
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}<br />
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\qc\b\f0\fs20 One\par<br />
Two\par<br />
Three\par<br />
Four\par<br />
Five\par<br />
\pard\b0\par<br />
}<br />

How I get this is, write words One,Two,Three,For,Five on the word pad and do some text formating on it, like bold, change color and few. Then save it as RTF file and open it using notepad. The content is like above. From this content I want to extract written words by me.

Can you guys give some clue for me.

I appreciate your help all the time...

Try to feed with RTF the CP article search engine, maybe a wonderful world is awaiting for you.

Ok, I have start work in this way. Read the file and get the content to a buffer. Then processing it until either '\' or '{' not find, so it should be a text word. Here is the code.

main function

<br />
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])<br />
{<br />
	int nRetCode = 0;<br />
<br />
	// initialize MFC and print and error on failure<br />
	if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))<br />
	{<br />
		// TODO: change error code to suit your needs<br />
		_tprintf(_T("Fatal Error: MFC initialization failed\n"));<br />
		nRetCode = 1;<br />
	}<br />
	else<br />
	{<br />
		// TODO: code your application's behavior here.<br />
		CFile rtfFile;// RTF file object<br />
		bool err = rtfFile.Open("G:\\Work On\\CPP\\Counter\\TestFile.rtf", CFile::modeReadWrite, NULL);<br />
<br />
		if(err != 0)<br />
		{<br />
			// Use the file size buffer<br />
			int length = rtfFile.GetLength();<br />
			char *pbuff = new char[length];<br />
<br />
			// Read the file to buffer<br />
			rtfFile.Read(pbuff, length);<br />
<br />
<br />
			CString text(getText(pbuff));<br />
<br />
			cout << (LPCTSTR)text;<br />
			<br />
			<br />
		}<br />
	}<br />
<br />
	return nRetCode;<br />
}<br />

getText function

<br />
CString getText(const CString & rtf)<br />
{<br />
	CString strCopy;// Hold the text<br />
	CString ch;// For next character<br />
	CString str(rtf.GetAt(1));<br />
	//CString str=rtf.GetAt(1);<br />
<br />
	BOOL bBrace = FALSE;// for '{'<br />
	BOOL bSlash = FALSE;// for '\'<br />
	BOOL bFirstLetter = FALSE;// first letter after the '\' sign<br />
<br />
	int nLength = rtf.GetLength();// Get the length again<br />
<br />
	// Just use as the dummy conditions. Length should be more that one<br />
	if (nLength < 4)<br />
	{<br />
		return "";<br />
	}<br />
<br />
	// Loop the length until find the EOF, using length of the RTF file<br />
	for (int i = 0; i < nLength; i++)<br />
	{<br />
		ch = rtf.GetAt(i);<br />
<br />
		if (ch.Find('\\') != -1)<br />
		{<br />
			bSlash = TRUE;<br />
			continue;<br />
		}<br />
		else if (ch.Find(' ') != -1)<br />
		{<br />
			bSlash = FALSE;<br />
			//Let it fall through so the space is added<br />
			//if we have found first letter<br />
			if (!bFirstLetter)<br />
			{<br />
				continue;<br />
			}<br />
		}<br />
		else if (ch.Find('{') != -1)<br />
		{<br />
			bBrace = TRUE;<br />
			bSlash = FALSE;<br />
			continue;<br />
		}<br />
		else if (ch.Find('}') != -1)<br />
		{<br />
			bSlash = FALSE;<br />
			bBrace = FALSE;<br />
			continue;<br />
		}<br />
<br />
		if (!bSlash && !bBrace)// check both '\' and '{' are avoided<br />
		{<br />
			if (!bFirstLetter)// set the first letter<br />
			{<br />
				bFirstLetter = TRUE;<br />
			}<br />
			strCopy += ch;<br />
			continue;<br />
		}<br />
	}<br />
	return strCopy;<br />
}<br />

My question is I can call the getText function inside the main function, gives an compilation error. Error is this,

unresolved external symbol "class ATL::CStringT<char,class strtraitmfc_dll<char,class="" atl::chtraitscrt<char=""> > > __cdecl getText(class ATL::CStringT<char,class strtraitmfc_dll<char,class="" atl::chtraitscrt<char=""> > >)" (?getText@@YA?AV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@V12@@Z) referenced in function _main</char,class></char,class>

Can you tell me where I'm going wrong.

I appreciate your help all the time...

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)

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)

CPallini11-Dec-07 0:54

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

11-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.

I will try it
