    Im using this functiuon here:

    UINT GetDlgItemText(HWND hDlg,
    int nIDDlgItem,
    LPTSTR lpString,
    int nMaxCount

    I have all the parameters apart from 'int nIDDlgItem'
    I have no idea where or how to get this. I've looked at some example, I see alot of IDC_????
    I tried to look these up to no avail.

    Could someone tell how i woulg go about finding this value, or the function calls to use?

    Use the MAKEINTRESOURCE macro... like
    ::GetDlgItemText(hDlg, MAKEINTRESOURCE(IDC_SOMETHING), Str, StrLen);
    Where IDC_SOMETHING is the ID of the control you want to get text from

    ok i saw a post down the list, it said you can use the resourse editor, this edit box i am trying to recieve text from is an another application.
    so im not sure about how to do the equivilient, i used spy++ to see if i could see anything, i closest thing i found saw under cursor handle: IDC_SIZE which dosent work

    Maybe you can just use WM_GETTEXT? You don't have to specify an identifier for that.

    Also, you can retrieve the identifier using GetDlgCtrlID(). That should work.

    ok, i eventually found it on MSDN, the function cant be called to retrieve text from other processes.

    the solution in case anyone has the need: is to simple copy to the the windows clipboard as all processes have access to this function

    or, as bennyandthejets pointed out, you can use GETTEXT. If you can get the HWND of the edit box in question (p'haps using EnumWindows and EnumChildWindows) you can simply use:

    SendMessage(hEditWnd, WM_GETTEXT, MINSIZE, (LPARAM)buff);
    its true you cant use GetDlgItemText or GetWindowText accross processes, but you can use WM_GETTEXT. Its cos the former two functions have some sort of security built in - I think it was to avoid people hacking passwords in password edit boxes, which you can still do with WM_GETTEXT!!
