DateTime Picker的按钮

Question

我正在创建一个触摸屏应用程序，我使用两个数据采集器，但DateTimePicker的按钮太小，所以我决定将一个按钮覆盖到datatimepicker的按钮，但是用于显示月视图的代码是什么？

Answer 1

试试这个，button1是你的大按钮......

[DllImport("user32.dll", SetLastError = true)]
private static extern int SendMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);

private const uint WM_SYSKEYDOWN = 0x104;

private void button1_Click(object sender, EventArgs e)
{
    SendMessage(dateTimePicker1.Handle, WM_SYSKEYDOWN, (int)Keys.Down, 0);
}
