TextBox

[Notsosuperhero]

How would I get the text in a textbox in a dialog box to a TCHAR or LPSTR to be able to add to a list box on the Parent Window?

By using the GetDlgItemText() function:


TCHAR szBuff[256] = ""; // Size it here, if you expect longer strings than that
GetDlgItemText(hDlg, IDC_YOUR_EDIT_BOX, szBuff, sizeof(szBuff));


Where hDlg is the HWND of your dialog and IDC_* the ID of your edit control. After this call you will find the text of the edit box in szBuff.

Actually if TCHAR happens to be WCHAR the calculation of buffer length should be

sizeof szBuff / sizeof szBuff[0]

Of course thank you for correcting me. In addition you can also define the size as a macro:


#define BUFFER_SIZE 256

TCHAR szBuff[BUFFER_SIZE] = "";
GetDlgItemText(hDlg, IDC_MY_EDIT_BOX, szBuff, BUFFER_SIZE);


So additional resizing of the buffer size will be easy by just modifing the macro.
