Simple Converting Help

[Spilled]

I'm having a hard time setting my text to my chat window. I've tried plenty of things but cant get it to work. Always get this error saying i cannot convert. Any help is appreciated thanks all. No Flaming please simple question.

Code Select Expand


       int wtl;
       wtl = GetWindowTextLength(SendBar);
       char wt[wtl];
       std::string strString;
       strString = GetWindowText(SendBar, wt, wtl);
       SetWindowText(TextBox, strString);


Error: cannot convert `std::string' to `const CHAR*' for argument `2' to `BOOL SetWindowTextA(HWND__*, const CHAR*)'

Tried?

Code Select Expand


SetWindowText(TextBox, strString.c_str());

Code Select Expand


        case WM_COMMAND:
            switch(LOWORD(wParam))
            {
               case Send_Bar:
                    switch(wParam / 0x10000)
                    {
                    case EN_CHANGE:
                         int wtl;
                         wtl = GetWindowTextLength(SendBar);
                         char wt[wtl];
                         std::string strString;
                         strString = GetWindowText(SendBar, wt, wtl);
                         SetWindowText(TextBox, strString.c_str());
                    break;
                    }


With this i enter anything in the send bar and it closes, ideas?

Edit:
Also how would i go about converting a string into an integer? Thanks again.

                         int wtl = GetWindowTextLength(SendBar);
                         char wt[wtl + 1];
                         GetWindowText(SendBar, wt, sizeof(wt));
                         SetWindowText(TextBox, wt);


Much, much simpler.

A couple of points to the original poster. Firstly EN_CHANGE message can be extracted by using the HIWORD macro, there is no need to do this:

Code Select Expand


wParam / 0x10000


Use this instead:-

Code Select Expand


HIWORD(wParam)


Secondly, you do realize that a EN_CHANGE is sent to you for every change, ie. when a single character is typed. It might be more appropriate to copy the text when the user presses a button or something and do it in one go.

He probably wants the title of the window to change as the text is typed...as in NBBot.

See atoi().

strtol(3) and strtoul(3) are far superior to atoi!

[K]

strtol(3) and strtoul(3) are far superior to atoi!

While we're listing our favorites, you could also use a std::stringstream or the boost::lexical_cast operator.

It doesn't matter for this particular poster, but it's worth pointing out that both my suggestion and Arta's work in a pure C environment, whereas K's do not.
