<br />        private void treeView1_DragEnter(object sender, DragEventArgs e)<br />        {<br />            if ( e.Data.GetDataPresent("System.Windows.Forms.TreeNode") )<br />            {<br />                e.Effect = DragDropEffects.Copy;<br />     

<br />存储过程定义：<br />Create PROCEDURE [dbo].[sp_CreateSQL]<br />@name varchar(1000),<br />@sql varchar(7000),<br />@i int output<br />AS<br />BEGIN<br />declare @sql1 varchar(7000)<br />set @sql1 = 'Create View '+ @name +' as '+@sql<br />exec

<br /><br />运行如图，请教各位当窗口关闭时，报错，怎样修改？<br />另外复制过程中，点击“取消”，怎么实现啊？
