content passing in dialog box?

hi,
i am to new to windows programming.(Non - MFC)
i have create an application having 2 dialog boxes. i have to take input in the editbox of first dialog box.
and to display it on static text field of second dialog box.
i have created dialog boxes but i need to know how i pass contents of edit box to other dialog box.

Please help me.

So, you'd need to retrieve the text from your edit control, store that and then transfer it to your static control. You could try something like what is shown below, though it's an old, layman's way of doing it.

Code:

---

                char* temp_buf;
                std::string AddString;
           
                int len = GetWindowTextLength(GetDlgItem(hwnd,ID_EDITBOX));
             
                if(len > 0 )
                {
                temp_buf = (char*)GlobalAlloc(GPTR, len + 1);
                GetDlgItemText(hwnd, ID_EDITBOX, temp_buf, len + 1);
               
                AddString = temp_buf;

                SetDlgItemText((HWND)hwnd,IDS_STATICBOX, AddString.c_str());

                GlobalFree((HANDLE)temp_buf);
                }

Is the second dialog a child of the first?

If so you can use GetParent()

Code:

---

char szBuf[MAX_PATH]={0}; // dynamic memory alloc is not required as edit has set limit lower than MAX_PATH and GetDlgItemText checks buffer size

if(GetDlgItemText( GetParent(h2ndDlg), IDC_EDIT1, szBuf, MAX_PATH-1))//we got text
{
      SetDlgItemText( h2ndDlg, IDC_STATIC1 , szBuf);
}
//else handle error.

That's incorrect.

When the system creates an edit control, it automatically creates a text buffer, sets its initial size, and increases the size as necessary. The size can be up to a predefined limit of approximately 32 kilobyte (KB) for single-line edit controls

Sure, you can set a limit so that your statement is true, but it's not in general. For example, the initial size on Win7 as reported by EN_GETLIMITTEXT is 30000 chars.

Sorry bad editing.

I thought I said 'you can set the limit lower than MAX_PATH but this is not required as GetDlgItemText checks buffer length.'

The default text lenght is 32,767 characters for edits (unless rich).

EDIT: BTW the limit is only on text the USER enters, the limit is not checked for programatically entered text.
