从文本框中检索数据以从SQL Server中获取标签 [英] Retrieve the data from text box to label from sql server

问题描述

嗨
1)我已经在窗口应用程序中创建了一种形式.文本框包含时间，一个用于AM和PM用户的组合框将放置时间，然后他将选择AM或PM，但是我不明白如何将其同时放置在sql server中，也不了解如何加入它们.
================================================== ==========================
2)我采用了一个分组框，因为我放入了三个文本框和三个标签，意味着一行包含六个信息.
我想在文本框中执行sql连接，以便如果用户在文本中输入信息，并且应该在标签中检索数据.

================================================== ==========================
3)在分组框中，我放置了一个添加按钮，我希望如果用户单击添加"按钮，则下一行应在分组框中可见.我已经将所有文本框和标签都设为enable = false.
我已经为此编写了代码，但这给了我错误，这里是代码

推荐答案

1.代码中有什么错误?
2.

1. what is the error in the code?
2.

frmsalesorderbooking.Control.Add(gb);

此行应该引发错误，因为您无法修改类，请在此处使用对象

This line should be raising error as you cannot modify class, use object instead which is

f2

代替.
