asp.net - OnTextChanged event is not firing -

-

i have textbox inside aspx page

 <ajax:updatepanel id="updatepanel2" runat="server">         <contenttemplate>       <asp:textbox id="txtcity" autopostback="true" ontextchanged="txtcity_textchanged"              width="90%" runat="server" ></asp:textbox>        </contenttemplate>        </ajax:updatepanel>

code behind:

   protected void txtcity_textchanged(object sender, eventargs e) {     lblmessage.text = "you have typed:" + txtcity.text; ; }

and lblmessage [on same aspx page]

  <ajax:updatepanel id="updatepanel1" runat="server" updatemode="conditional">         <contenttemplate> <asp:label id="lblmessage" runat="server" text="" ></asp:label> </contenttemplate> </ajax:updatepanel>

but when typing in textbox. lblmessage not updating.

how rectify this?

it sounds you're thinking ontextchange event fired while typing in text box. not true. ontextchange server-side event , fires when page (or panel) posted back. typing text box on page not post page , event fire once submit form.

what want in case, use javascript onkeypress javascript event update label text things typed textbox. javascript run on client , doesn't require post page in order run.

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

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

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...
