[RESOLVED] RTF file reader

Hi all,

I want to read a RTF file and get the text only from it. So I tried the following code.

Main function.

Code:

---

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
        int nRetCode = 0;

        // initialize MFC and print and error on failure
        if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
        {
                // TODO: change error code to suit your needs
                _tprintf(_T("Fatal Error: MFC initialization failed\n"));
                nRetCode = 1;
        }
        else
        {
                // TODO: code your application's behavior here.
                CFile rtfFile;// RTF file object
                bool err = rtfFile.Open("G:\\Work On\\CPP\\Counter\\TestFile.rtf", CFile::modeReadWrite, NULL);

                if(err != 0)
                {
                        // Use the file size buffer
                        int length = rtfFile.GetLength();
                        char *pbuff = new char[length];

                        // Read the file to buffer
                        rtfFile.Read(pbuff, length);

                        CString text(getText(pbuff));

                        //cout << (LPCTSTR)text;
                }
        }
        return nRetCode;
}

getText function.

Code:

---

CString getText(const CString & rtf)
{
        CString strCopy;// Hold the text
        CString ch;// For next character
        CString str(rtf.GetAt(1));

        BOOL bBrace = FALSE;// for '{'
        BOOL bSlash = FALSE;// for '\'
        BOOL bFirstLetter = FALSE;// first letter after the '\' sign

        int nLength = rtf.GetLength();// Get the length again

        // Just use as the dummy conditions. Length should be more that one
        if (nLength < 4)
        {
                return "";
        }

        // Loop the length until find the EOF, using length of the RTF file
        for (int i = 0; i < nLength; i++)
        {
                ch = rtf.GetAt(i);

                if (ch.Find('\\') != -1)
                {
                        bSlash = TRUE;
                        continue;
                }
                else if (ch.Find(' ') != -1)
                {
                        bSlash = FALSE;
                        //Let it fall through so the space is added
                        //if we have found first letter
                        if (!bFirstLetter)
                        {
                                continue;
                        }
                }
                else if (ch.Find('{') != -1)
                {
                        bBrace = TRUE;
                        bSlash = FALSE;
                        continue;
                }
                else if (ch.Find('}') != -1)
                {
                        bSlash = FALSE;
                        bBrace = FALSE;
                        continue;
                }

                if (!bSlash && !bBrace)// check both '\' and '{' are avoided
                {
                        if (!bFirstLetter)// set the first letter
                        {
                                bFirstLetter = TRUE;
                        }
                        strCopy += ch;
                        continue;
                }
        }
        return strCopy;
}

But I got an error on main function, when I call the getText function to find the text. I can't find any solution for that. Can you guys give a clue to me.

What is the error? Its no doubt some sort of less-descriptive-than-a-linker-error MFC Error.

chem

Here it is,

Code:

---

unresolved external symbol "class ATL::CStringT > > __cdecl getText(class ATL::CStringT > >;)" (?getText@@YA?AV?$CStringT@DV?$StrTraitMFC_DLL@DV?$ChTraitsCRT@D@ATL@@@@@ATL@@V12@@Z) referenced in function _main

---

Actually I found the error, just passing the CString to the getText() it works, like getText(const CString rtf).

But why is that.

And also I have another question. I want to find the '\pard' of the rtf CString and replace it with a space. I try this inside the for loop,

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

But it wont work. Any idea about that...

Okay..

Is getText() declared? Are they in the same files? Are the files included for the getText() function?

Yes, it is declared as follows.

Code:

---

CString getText(CString);

You mean both main function and the getText? Yes, both are in same file.

You mean header files? Use all the required header files.

Here is my full code.

Looks to me like you're passing a char pointer into the getText function.. when it expects it to be a CString type..

chem

Yes that is, So I change the way I do this. Used RichEditControl. It's so easy, just two line of code need to do it.
