I have never tried to locate information about the xls file format.
However, there are Excel ODBC drivers out there that might be an idea to
look into - shouldn't be too much different from using a MySQL backend.

You have several options.  You can write out your text file in a 
delimited format and then when you read the file, tell it you want to 
read in a delimited file and tell it the delimiter.  You can delimit 
columns on white space (like spaces or tabs) or you can use a 
predefined character (like '^' or '|' or ',').  Someone's already 
posted how to print out with tabs.

OR, you can actually find out what the file format is for .xls files 
and write out your file in that format.  But that's going to be a bit 
more complicated and I don't know the .xls format.  You can probably 
dig it up with a little research and/or experimentation.

Hi Guillermo,
 
system ("cmd");  include <stdlib.h>
 
Of course provided that the command interpreter is named cmd.  There's also other calls such as spawn, etc.  Depends on whether you want a stand alone child process or not.

I would like to know how to get a command console to appear along with =

I have seen code from other people where along with the window app they =

I have even seen it in the FLTK example programs, but I can not get it =
to happen.

sorry if this belongs in another mailing list, thanks in advance.

Depends on how you store the name.

If it is a C string.

    str[0] = toupper(str[0]);

If it is a std::string you might do:

    std::string str = "hello world";
    str[0] = toupper(str[0]);

or you might try something fancy and use transformations:

    struct ToUpper {
        char operator() (char c) const { return std::toupper(c); }
    };

    ...

    std::string str = "hello world";

    std::transform(str.begin(),str.end(),str.begin(),ToUpper());

to convert the full string to upper case.

Hi, dev-c++ users,

I have a very basic question I can't solve. I want to upper the first letter 
of a sentence. For example I have: "john is tall". I want to turn this into 
"John is tall". How do I do that?

Thanks in advance!

Alexsandro.

take a look at CONIO library:

Hi there,

I was trying to port the code of a library to use it in my own project and I
found something interesting.

The problem is that if you have a class B, that extends another class A.
Then when using the template MyTemplateClass<B> does not have any
relationship with the class MyTemplateClass<A>.

You can see some experiments in the code presented below.

If someone has a more detailed documentation (specification) explaning why
this cannot be done I would appreciate.

Kind regards,

SetConsoleTextAttribute(), from Win32 API.
