Question

我是视觉工作室的新手。我正在使用VS2010，我正在尝试创建一个具有三个按钮的表单应用程序： CONNECT - 一个按钮，它提供与所连接的dsp的套接字连接并读取我发送的命令（例如握手命令），然后在控制台上显示它 MEASURE - 一个计算我想要的参数的按钮停止 - 退出程序，两个标签显示我的参数。问题是，CONNECT按钮中的代码有多个调用来读取和写入命令以及套接字连接代码。我观察到的是，除了套接字连接代码，它不会调用 readData（）或 writeData（）函数。我用谷歌搜索了几个小时，但显然没有成功。如果有任何错误或是否有任何其他替代解决方案可以让它工作，请告诉我。提前致谢。我的代码：

PS：当我在' private中定义这些函数时，它给出了错误：System :: Void button1_Click（System :: Object ^ sender，System :: EventArgs ^ e）{'

无法在VS2010的表单应用程序中调用函数
