InitializeComponent(); // TODO: Add any initialization after the InitializeComponent call } /**//// summary /// Clean up any resources being used. /// /summary protected override void Dispose( bool disposing ) { if( disposing ) { if(components ! null) { components.Dispose(); } } base.Dispose( disposing ); }// private void button1_Click(object sender, System.EventArgs e) { this.PluginHost.showStatus(txtFeedback.Text); } }} 具体代码可以参阅:下载开发演示文件 转载于:https://www.cnblogs.com/QPG2006/archive/2005/10/07/249662.html
