web_set_max_html_param_len是可以加长prarm的加度.以下是一个小例子:
web_set_max_html_param_len("1024");
           web_reg_save_param("Siebel_Analytic_ViewState4",
           "LB/IC=ViewState\" value=\"",
           "RB/IC=\"",
           "Ord=1",
           "Search=Body",
           "RelFrameId=1",
           LAST);

web_reg_save_param( "WCSParam_Diff1", "LB=Set-Cookie: VNum=", "RB=;", "Ord=1", "Search=Headers", "RelFrameId=1", LAST );
//以上程序如果不加,web_set_max_html_param_len("1024"),程序走到会错误信息:web_ url 最高严重级别为“ERROR”，175602 个正文字节，1553 个标头字节 [MsgId: MMSG-27178]
     web_url("UserLogin.aspx",
           "URL=http://oratest.chaotex.com/MAP/(b0jhdsn04qg0mj55etvsqay i)/UserLogin.aspx",
           "Resource=0",
           "RecContentType=text/html",
           "Referer=",
           "Snapshot=t1.inf",
           "Mode=HTML",
           EXTRARES,
           "Url=Skins/Purple/Logo.jpg", ENDITEM,
           "Url=/webctrl_client/1_0/treeview.htc", ENDITEM,
           LAST);

顶一下。
