I get the vague feeling I'm doing someone's homework.... You can either lookup CRichEditCtrl's StreamIn function or if you need a quick and dirty file reader (for small files), do something like:
FILE *fp = fopen(str,"r"); if (fp) { // goto the end of file fseek(fp, 0L, SEEK_END); // get the length of the file long fileLen = ftell(fp); // go back to the start of the file rewind(fp); // allocate buffer for file contents char* text = new char[fileLen + 1]; // read the file into the buffer fread(text, 1, fileLen, fp); // set the window text m_FCONT.SetWindowText(text); delete [] text; fclose(fp); } else { MessageBox("error opening file.",MB_OK | MB_ICONINFORMATION); return; }This code is totally untested, but should give you the general idea. Good luck!

The most important thing you need to do is Call
AfxInitRichEdit()function in u rInitInstance()of u r application.AfxInitRichEdit loads RICHED32.DLL to initialize version 1.0 of the rich edit control. Appu.. "If you judge people, you have no time to love them." -

You need a terminating null on the text (which I forgot): Change the lines in bold:
// allocate buffer for file contents **char* text = new char[fileLen + 1];** // read the file into the buffer fread(text, 1, fileLen, fp); **// null terminate the string text[fileLen] = 0;**VinayCool wrote:

Like I mentioned yesterday, you can do somthing like:
CHARFORMAT cf; memset(&cf, 0, sizeof(CHARFORMAT)); cf.cbSize = sizeof(CHARFORMAT); cf.dwMask = CFM_BOLD; cf.dwEffects = CFE_BOLD; // **** pseudo-code **** for (int i = 0; i < size of your word list; i++) { m_FCONT.SetSel(word_position[i], word_length[i]); m_FCONT.SetSelectionCharFormat(cf); }Hope that works!

Hi Steve Echols, Thank for helping me for completing my project. Code is working i declared these vaiables char word_position[50]; char word_length[50]; Steve how to pass the word ??? where i ahve to pass the word which has to be highlighted ?? I have stored the word here which has to be hightlighted w = m_WORD; ----------------------------------
CHARFORMAT cf; memset(&cf, 0, sizeof(CHARFORMAT)); cf.cbSize = sizeof(CHARFORMAT); cf.dwMask = CFM_BOLD; cf.dwEffects = CFE_BOLD; UpdateData(TRUE); CString w; w = m_WORD; int len = strlen(word); char word_position[50]; char word_length[50]; // **** pseudo-code **** for (int p = 0; p < len ; p++) { m_FCONT.SetSel(word_position[p], word_length[p]); m_FCONT.SetSelectionCharFormat(cf); }Regards, Vinay Charan.
