Why the extra step? sr --> dt --> str1 :confused: How about: str1.Format("%g", (LPCSTR) m_edit6.Left(3)); If you need the intermediate step, why not use atof() instead of strtod()? Anonymous wrote: this str1 contains a double value.i want to convert this double value into its ASCII value. Let me see if I have this right. If str1 contains the value 123.45, what exactly is it that you want it converted to? The ASCII value of 1 is 49, 2 is 50, etc. The ASCII value of the decimal is 46. How are you wanting to store these values? "Ideas are a dime a dozen. People who put them into action are priceless." - Unknown

Someone posted working string to double code before, then deleted the post, I guess they realised their question was non-existant. This code requires you to include cstdlib. char *stop = 0; char * testvar="123.4"; double x=strtod(testvar, &stop); What do you mean by string to ASCII ? Christian Graus - Microsoft MVP - C++

If your file is not so big, and if your project is link to MFC as shared lib, you can use the class CString to handle the text file. e.g. CString tmp(buffer); // where buffer contains data read from your file CString replaceString("myreplacestring"); while(tmp.Replace(" ",replaceString)); // Not all string like " " will be replace by "myreplacestring" and not " " THink this helps you

I'm guessing that you already have code on the server side that handles client requests. Yes? "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow

If you add to a file, it's going to increase in size. There is no way around this. This is a very odd requirement. "Opinions are neither right nor wrong. I cannot change your opinion. I can, however, change what influences your opinion." - David Crow

here is small code that compare current date with your stored date. My date Format is YYYY-MM-DD, i Believe,you are smart Enough to modify the code according to your need. BOOL ::FnCheckForValidDates(CString szEndDate) { //Get Current date CTime TodayDate=CTime::GetCurrentTime(); int nYear,nMonth,nDay; //date format YYYY-MM-DD ///Extract Year nYear=\_ttoi(szEndDate.Left(szEndDate.Find('-'))); ///remove the Year from String szEndDate.Replace(szEndDate.Left(szEndDate.Find('-')),""); ///Replace Extra '-' szEndDate.TrimLeft('-'); ///Extract Month nMonth=_ttoi(szEndDate.Left(szEndDate.Find('-'))); ///remove the Year from String szEndDate.Replace(szEndDate.Left(szEndDate.Find('-')),""); ///Replace Extra '-' szEndDate.TrimLeft('-'); ///Extract Day nDay=\_ttoi(szEndDate); ///comparison Routine ///first Check year if(TodayDate.GetYear()>nYear) return FALSE; if(TodayDate.GetMonth()>nMonth) return FALSE; if(TodayDate.GetDay()>nDay) return FALSE; #ifdef MYDEBUG AfxMessageBox("Returning True"); #endif return TRUE; } [Vote One Here, Complete my Survey....] Alok Gupta visit me at http://www.thisisalok.tk          "I Think Believe this Will Help"
