各位大侠，我设计BBS时遇到一个问题，就是按了关闭按钮之后，窗口还是不会关闭，具体代码如下：
//运行一段客户端代码,用于关闭窗口
String sScript = "<script language=JavaScript> " ;
sScript += "window.close();";
sScript += "</script>";
if(!this.IsClientScriptBlockRegistered("MyScript"))
{
this.RegisterClientScriptBlock("MyScript", sScript);
}

}
catch(Exception exp)
{
Response.Write(exp.Message);
}
oConn.Close();

这么写， button.Attribute.Add("OnClick","写js的window.close()");

按照笨笨姐和上面大哥的方法都还是不行啊

具体情况是这样的，我在帖子列表按“发新帖子”按钮时就会用窗口模式弹出发新帖子窗口，填好新帖子标题和内容，按“发帖：按钮，它就再闪出一个窗口，但这个窗口的内容是看不到的，只是很快的闪一下，然后发新帖子窗口就不会关闭，等自己X了它，原来帖子列表就会增加刚才输入增加的帖子。
请各位大侠帮帮忙啊，毕业设计的时间快到拉

以下是增加帖子的代码：
//增加新主题
public void addNewTopic(object sender, System.EventArgs e)
{
//基于连接的insert
string sql = "insert into T_Topic (fchrTopicID,fchrTopicCaption,fchrTopicDetail,fchrOperatorID,fdtmDate,fbitIsTOP,fbitIsGood,fbitNoUsed,fchrFunctionID)"+
" values(@fchrTopicID,@fchrTopicCaption,@fchrTopicDetail,@fchrOperatorID,@fdtmDate,@fbitIsTOP,@fbitIsGood,@fbitNoUsed,@fchrFunctionID)";
SqlConnection oConn = new SqlConnection(CONNSTRING);

SqlCommand oCommand = new SqlCommand(sql,oConn);
oCommand.Parameters.Add(new SqlParameter("@fchrTopicID",SqlDbType.UniqueIdentifier,16));
oCommand.Parameters.Add(new SqlParameter("@fchrOperatorID",SqlDbType.VarChar,50));
oCommand.Parameters.Add(new SqlParameter("@fchrFunctionID",SqlDbType.VarChar,50));
oCommand.Parameters.Add(new SqlParameter("@fchrTopicCaption",SqlDbType.VarChar,50));
oCommand.Parameters.Add(new SqlParameter("@fchrTopicDetail",SqlDbType.VarChar,1000));
oCommand.Parameters.Add(new SqlParameter("@fdtmDate",SqlDbType.DateTime,8));
oCommand.Parameters.Add(new SqlParameter("@fbitIsTop",SqlDbType.Bit ,1));
oCommand.Parameters.Add(new SqlParameter("@fbitIsGood",SqlDbType.Bit ,1));
oCommand.Parameters.Add(new SqlParameter("@fbitNoUsed",SqlDbType.Bit ,1));

string strUID="";
string strFunctionID="";
strUID = Request.QueryString["UID"];
strFunctionID = Request.QueryString["id"];
InnerFunction oFunction = new BusObjectForum.InnerFunction();

oCommand.Parameters["@fchrTopicID"].Value = oFunction.getNewID();
oCommand.Parameters["@fchrOperatorID"].Value= "{" + strUID + "}";
oCommand.Parameters["@fchrFunctionID"].Value= "{" + strFunctionID + "}";
oCommand.Parameters["@fchrTopicCaption"].Value=txtCaption.Text;
oCommand.Parameters["@fchrTopicDetail"].Value=txtDesc.Text;
oCommand.Parameters["@fdtmDate"].Value=System.DateTime.Now;
oCommand.Parameters["@fbitIsTop"].Value=false;
oCommand.Parameters["@fbitIsGood"].Value=false;
oCommand.Parameters["@fbitNoUsed"].Value=false;

oConn.Open();
try //完成对数据库Insert的操作
{
oCommand.ExecuteNonQuery();
//运行一段客户端代码,用于关闭窗口
String stringBuffer = "<script language=JavaScript> " ;
stringBuffer += "window.close();";
stringBuffer += "</script>";
if(!this.IsClientScriptBlockRegistered("MyScript"))
{
// this.RegisterClientScriptBlock("MyScript", stringBuffer);
Response.Write(stringBuffer);
// sScript
}
}
catch(Exception exp)
{
Response.Write(exp.Message);
}
oConn.Close();
}
