private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)        {            DataGridViewRow row = dataGridView1.CurrentRow;//获取选中的行数            try          

private void Form4_Load(object sender, EventArgs e)        {            get_fujiedian();        }         //根菜单        public void get_fujiedian()        {            DataTable dt

在WIn7下DragDrop事件为响应解决方案如下：

首先在父窗体定义：public Mechanism me = new Mechanism();     一定要是为全局变量，类型为public在子窗体中定义父窗体的变量：public Main mainin;//定义主窗体变量，给主窗体调用然后在父窗体按钮事件中写上： private void 机构管理ToolStripMenuItem_Click(obje

From1窗体： private void 号码导出ToolStripMenuItem_Click(object sender, EventArgs e)        {            this.Hide();            Export export = new Export();            export.ShowDialog();   

在Program.cs文件中修改： ///         /// 应用程序的主入口点。        ///         [STAThread]        static void Main()        {            try            {                Application.EnableVisual

/// /// 获取当前客户端操作系统 /// /// private string getOSVersion() { try { string osVersion = string.Empty; Re
