the reason posted entire masterpage has multiple contentplaceholders in table format.....

my content page looks this

<%@ page title="" language="c#" masterpagefile="~/officeapps.master" autoeventwireup="true"     codefile="usersgrid.aspx.cs" inherits="usersgrid" %>  <asp:content id="content1"

<asp:content id="content4" contentplaceholderid="contentplaceholder3" runat="server"> </asp:content>

my problem when have validate using below code inside contentplaceholder validation not being done code is

<script type="text/javascript">        $.validator.addmethod("regex",function(value, element, regexp)              {                 var check = false;                 var re = new regexp(regexp);              return this.optional(element) || re.test(value);             },"<p style='color:red'>*please check input</p>");            $(document).ready(function() {             $("#aspnetform").validate({                 rules: {                     <%=tb_username.uniqueid %>: {                         minlength: 5,                         required: true,                      regex: "^[a-za-z0-9'.\\s\]{3,15}$"                       },                     <%=tb_name.uniqueid %>: {                         minlength: 5,                         required: true,                     regex: "^[a-za-z0-9'.\\s\]{3,15}$"                      },                     <%=tb_sname.uniqueid %>: {                         required: true,                     maxlength:4,                     regex: "^[a-za-z0-9'.\\s\]{1,4}$"                      },                     <%=tb_email.uniqueid %>: {                      required: true,                     regex:"^[a-za-z0-9._-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}$"                     },                     <%=tb_phone.uniqueid %>: {                         minlength: 8,                         maxlength: 8,                         required: true,                     regex:"^[0-9\s]{8}$"                     },                     <%=tb_mobile.uniqueid %>: {                         minlength: 10,                         maxlength:10,                         required: true,                         regex:"^[0-9\s]{10}$"                     }                 },                  messages: {                     <%=tb_username.uniqueid %>:{                          required: "please enter username",                          minlength: "user name must atleast of 5 characters"                      },                      <%=tb_name.uniqueid %>:{                          required: "please enter name",                          minlength: "name must atleast of 5 characters"                      },                      <%=tb_sname.uniqueid %>:{                          required: "please enter shortname",                        maxlength:"shortname cant exceed 4 characters"                     },                      <%=tb_email.uniqueid %>:{                          required: "please enter email",                       },                     <%=tb_phone.uniqueid %>:{                          required: "please enter phone",                        minlength:"phone number should have 8 digits",                       maxlength:"phone number should have 8 digits only"                     },                   <%=tb_mobile.uniqueid %>:{                          required: "please entermobile number",                          minlength: "mobile number should have 10 digits"                         maxlength:"mobile number should have 10 digits only"                     }                     }             });         });     </script>

why not use asp.net validators, same thing you're trying do, plus server side validation!

  • regularexpressionvalidator(can used min , max length)
  • requiredfieldvalidator

server side validation must because javascript can disabled or modified user.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
