C++ Question Options

[Capn_Fish]

I'm making a program for the Z that I need to take a variable and use it as part of a "system (xxxx)" command (or some other command to have the program call another command with args). How do I do that? Sorry if a) this is really obvious or this question doesn't make sense. I have very little C++ knowledge, but am trying to learn.

Links to a solution would also be appreciated.

Thanks in advance.

Is there any way to only use one string-like variable (char[xyz] or string) in my code? Some things complain if I use a char[xyz], but not a string, others work the opposite way, and it would be easier to just use one type instead of converting back and forth.

Thanks.

sounds like QString is what you want

I'm not using QT. Is that an issue?

Is it possible to just use either strings or character arrays?

I guess there is no easy way out but to convert them back and forth. Not too familiar with the string definition in QT3, but there might be some cast members that return a pointer from string that can be used as a char pointer in some functions.

Using MFC (Microsoft Foundation Classes) as an example,

CString sMyText;
char szMyText[100];
char * lpszMyText;
sMyText = "Some data here";
lpszMyText = sMyText.GetBuffer(sMyText.GetLength());
// Use lpszMyText

strcpy(szMyText, lpszMyText);

lpszMyText = NULL; // Not required but good practise to null the pointers

// Release buffer pointer
sMyText.ReleaseBuffer();

Hope this make sense.
