Anyone know how. the default seems to be left alignment. Also anyone know how to use the sleep function and what I have to include to get it to work. This is all in Visual C++

anyone know what the command is to clear the screen.
is there any easy way to give a C++ program a GUI feel. VB has the drag and drop thing going does VC++ have anything similar?
is there a way to read in a file name during a program and then open it.
I was thinking something like:
cin >> FileName;
myin.open(FileName);
but myin.open doesn't like a string variable there it just seems to want myin.open("file.txt");
Any suggestions?
Help please! Anyone?
output streams like cout are instances of the ostream class or classes derived therefrom. ostream has a number of manipulator functions and can use a number of ios class flags. You can review the options in chapter 16 of J. Liberty's book Teach Yourself C++ in 21 days available at the following site in full text version.

The clear screen topic is a common one addressed on this board many times, and may even be in the FAQ section, although I haven't looked as I use Borland compilers which have the conio.h file that includes the clrscr() function. Unfortunately conio.h is not a standard file and is not available in all compilers. You can search this site for other options.
Borland C++ Builder reportedly has a system of drag and drop similar to VB. Since I don't use VB or VC++ I can only report what I have heard.
The open() function of streams only takes c_style (null terminated char arrays) strings as parameters. If you use other style strings you must convert them to c_style strings to be used in open().
