Append data to the end of a file

MFC append data at the end of the file:

Bool cdeldlg: writetofile (cstring svalue) {cstring sfile = getexepath () + "\ 1.log"; cstdiofile; If (file. open (sfile, cfile: modecreate | cfile: modewrite | cfile: modenotruncate) {file. seektoend (); // move the file pointer to the end of the file. writestring (svalue); file. close ();} return false ;}

Getexepath ()CodeAs follows:

// Return the directory of the executable file (excluding the final '\') cstring getexepath () {char sfilename [256] = {0 }; cstring Spath = _ T (""); getmodulefilename (AfxGetInstanceHandle (), sfilename, 255); Spath. format ("% s", sfilename); int Pos = Spath. reversefind ('\'); If (Pos! =-1) Spath = Spath. Left (POS); elsespath = _ T (""); Return Spath ;}
