请附上我的代码:

<?PHP 
session_start();
if (isset($_POST["usernameform"])){ 

$username = $_POST['usernameform'];
$password1 = $_POST['passwordform'];


$user_name = "XXXX";
$password = "XXXXX";
$database = "XXX";
$server = "XXXX";

$db_handle = mysql_connect($server, $user_name, $password);
$db_found = mysql_select_db($database, $db_handle);


$SQL = "SELECT * FROM login WHERE Username = '$username' AND Password = '$password1' "; //grab all the records from table
$result = mysql_query($SQL)
    or die("Error:" . mysql_error());

if (mysql_num_rows($result) > 0){ //if username and password match return number of rows is always 1

$_SESSION['login'] = $username; //by …

我的C#代码目前遇到了一个奇怪的问题.我试图使用folderBrowserDialog来检索用户选择的文件夹的路径.

一旦用户单击按钮确认选择(所选路径显示在"textBox1"中),如果找到文件夹位置,则应返回消息"建立连接"(如果找到目录/文件)或"无连接"发现"(如果文件/目录不存在).

然而,由于一些奇怪的原因,在检查目录是否存在时,代码似乎总是返回false - 是的,它确实存在.我的应用程序在它的清单文件中请求管理员权限,因为我认为这可以解决问题,所以我仍然难以接受这个问题.

private void button1_Click(object sender, EventArgs e)
{
  //BROWSE 
  folderBrowserDialog1.ShowDialog();
  textBox1.Text = folderBrowserDialog1.SelectedPath;
}

private void button2_Click(object sender, EventArgs e)
{
  var path = textBox1.Text + @"\" + "connection.pss";
  //ESTABLISH CONNECTION

  if (textBox1.TextLength > 0)
  {
    if (Directory.Exists(path))
    { 
      connectionstatus.Text = "CONNECTION ESTABLISHED!";
      //SET UP VARIABLES
    }

    if (!Directory.Exists(path))
    {
      connectionstatus.Text = "NO CONNECTION FOUND!";
    }
  }
}
