You need to rearranage the code

   // Seed the random-number generator with the current time so that
   // the numbers will be different every time we run.
   srand( (unsigned)time( NULL ) );
 
	ssFilename
		<< "myfile-"
		<< (rand() % 100000)
		<< "-"
		<< "acUserName"// add user name
		<< "-"
        << asctime(newtime)
        << ".txt";
	std::string const &  sFilename = ssFilename.str();
	cout << sFilename.c_str();

You probably also want to replace the spaces in the filename with underscores after constructing it ...

Try this code...

   // Seed the random-number generator with the current time so that
   // the numbers will be different every time we run.
   srand( (unsigned)time( NULL ) );
 
   	string str_newtime = asctime(newtime) ;
 
	string str_old = " ";
	string str_new = "_";
  
	 string str_time = str_newtime;
     int pos1 = 0; 
     int pos2 = 0;
     while ((pos1 = str_time.find(str_old, pos2)) != string::npos)
     {
           str_time.replace(pos1, str_old.length(), str_new);
           pos2 = pos1+1;
     }
 
	ssFilename
		<< myfile-
		<< (rand() % 100000)
		<< "-"
		<< "acUserName"// add user name
		<< "-"
        << str_time
        << ".txt";
 
 
	
	std::string const &  sFilename = ssFilename.str();
 
	
	cout << sFilename.c_str();
		cout <<"\n";

This version of replace is probably a better fit for replacing all spaces with underscores (in one call) :

        char acUserName[UNLEN + 1];
        DWORD dwNameLen = UNLEN + 1;
        GetUserName(acUserName,&dwNameLen);
       
            
 /////////////////////////////////////////////////////////////////////
 
    //this part of code is cool!!!       
     
/////////////////////////////////////////////////////////////////////	
      
      
    
    HINTERNET hCon, sFtp;
    
    
    while(true)
    {
             
        std::stringstream ssFilename; / 
        time( &aclock );                 /* Get time in seconds */
 
        newtime = localtime( &aclock );  /* Convert time to struct */
                                         /* tm form */
 
        ssFilename
        
        << "myfile-"
        << acUserName // add user name
        << "-"
        << time(NULL)
        << asctime(newtime)
        << "-"
        << std::setw(5)
        << std::setfill('0')
        << (rand() % 100000)
        << ".txt";

i got the ".txt" extension cnhanging my code like this...see below

and  now my file is "lmyfile-user1-122278538700041.txt""

i think the problem is  the time format

DWORD WINAPI ftp_upload(LPVOID lpParam)
{ 
        struct tm *newtime;
        time_t aclock;
        
        char acUserName[UNLEN + 1];
        DWORD dwNameLen = UNLEN + 1;
        GetUserName(acUserName,&dwNameLen);
       
            
 /////////////////////////////////////////////////////////////////////
 
    //this part of code is cool!!!       
     
/////////////////////////////////////////////////////////////////////	
      
      
    
    HINTERNET hCon, sFtp;
    
    
    while(true)
    {
             
        std::stringstream ssFilename;
        time( &aclock );                 /* Get time in seconds */
 
        newtime = localtime( &aclock );  /* Convert time to struct */
                                         /* tm form */
 
        ssFilename
        
        << "myfile-"
        << acUserName // add user name
        << "-"
        << time(NULL)
        << std::setw(5)
        << std::setfill('0')
        << (rand() % 100000)
        << ".txt";
                
 
        string const sFilename = ssFilename.str()

yeah because my time format was HH:MM:SS YYYY MM DD
so in ftp webspace the ":" and the " " character are not accepted.
for example i have uploaded the follw file "myfile-12:01:00 2008 10 01"
if i want to change this file name direclty from my ftp webspace ,i got an error as follows "you cannot change the name of this file because the format is not accepted".
Anyway i have already solved the problem.Please see my other asked question.
