So i have a textbox :

        hwndEdit = CreateWindow(TEXT("Edit"), NULL, WS_CHILD | WS_VISIBLE | WS_BORDER,
                50, 50, 150, 20, hwnd, (HMENU) ID_EDIT,
                NULL, NULL);

And i have a button

        hwndButton = CreateWindow( TEXT("button"), TEXT("Color it !"),
            WS_VISIBLE | WS_CHILD,
            50,100,200,25,
            hwnd, (HMENU) ID_BUTTON, NULL, NULL);

and another texbox :)

       CreateWindow(TEXT("Edit"), NULL, WS_CHILD |  WS_VISIBLE | WS_BORDER,
                50, 150, 150, 20, hwnd, (HMENU) ID_EDIT,
                NULL, NULL);

Now i'm not familiar with Win32 codes but what i want to do is
:
1-Get the text from the first texbox on the button click and put it in a string
2-output string results in the second texbox.

So any heads up what functions i should use ?

Here's a tutorial series. You're going to want to look at the message loop bit. There's a menu on the left side with all the parts.

I understand Message loops, i just need the function that fetches text from Texboxs D:
GetDlgItem() perhaps ? i can't get it to work

Got this off of a website:

Getting Text from the Edit Box

The GetDlgItemText message can be used to retrieve text from the edit control:


GetDlgItemText(hwnd, nEditID, szString, nMax)


The szString parameter is an LPSTR, and nMax indicates the maximum number of characters that we can cope with. If the programmer needs to allocate memory dynamically for this, then a WM_GETTEXTLENGTH message can be sent to the control:

SendMessage( GetDlgItem( hwnd, nEditID), WM_GETTEXTLENGTH, 0, 0L)


The return value from this is the number of characters in the text control.
