想将输入编辑栏内的字符串输出,怎么弄?

//能够成功显示Dialog,但是无法显示输入的字符串,希望得到帮助,没分了!好人一生平安
BOOL CALLBACK AboutDlgProcrdure(HWND hDlg,
    UINT message,
    WPARAM wParam,
    LPARAM lParam)
{
    static HWND hWnd;
    static LPTSTR pszMem;
    switch (message)
    {
        case WM_INITDIALOG:
            hWnd = GetDlgItem(hDlg, IDC_EDIT1);
            GetWindowText(hWnd, pszMem, 100 + 1);
            SetWindowText(hWnd, (LPTSTR)NULL);
            return TRUE;
        case WM_COMMAND:
            switch (LOWORD(wParam))
            {
                case IDOK ://按这个键输出?
                    MessageBox(NULL, TEXT("UUU"), pszMem, 0);
                    return 0;
                case IDCANCEL:
                    EndDialog(hDlg, 0);
                    return 0;
            }
        break;
    }
    return FALSE;
}
