Question

我在Heroku中有一个Postgres表。 Heroku Data表示它有250行数据（正确），大小约为8.4MB。

我正在尝试清除用户表。

我通过CLI从外部连接到数据库：

[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

public Form3() {
    InitializeComponent();

}

private void button1_Click(object sender, EventArgs e) {
    Process p = Process.Start(@"path\app.exe");
    Thread.Sleep(200); // Allow the process to open it's window
    SetParent(p.MainWindowHandle, panel1.Handle);
}

我的数据在哪里？我只有一个数据库，这是正确的数据库。为什么private Process GetProcess() { //do some magic stuff and find actually running app return NewAppProcess; } private void button2_Click(object sender, EventArgs e) { Process p = GetProcess(); SetParent(p.MainWindowHandle, panel2.Handle); }丢失了，而C:\Users\user_>heroku pg:psql postgresql-db-12345 --app heroku-app --> Connecting to postgresql-db-12345 psql (10.4, server 9.6.9) WARNING: Console code page (437) differs from Windows code page (1252) 8-bit characters might not work correctly.
