asp.net - C# - Page Redirection not working properly -


i have following code in c#:

if (function.equals("larger50")) {       request req = new request();       string result = req.dorequest("function=" + function + "&num=" + number, "http://localhost:4000/handler.ashx");        if (result.equals("true") || result.equals("true"))       {             page.clientscript.registerstartupscript(page.gettype(), null, "window.open('http://localhost:4000/larger.aspx?num=" + number + "', '_newtab')", true);        }         if(result.equals("false") || result.equals("false"))        {              page.clientscript.registerstartupscript(page.gettype(), null, "window.open('http://localhost:4000/smaller.aspx', '_newtab')", true);        }         if(result.equals("error") || result.equals("error"))        {              page.clientscript.registerstartupscript(page.gettype(), null, "window.open('http://localhost:4000/errorpage.htm', '_newtab')", true);        }         session["result"] = result;        page.clientscript.registerstartupscript(page.gettype(), null, "window.location.href = 'results.aspx'", true); }

the result variable can have 1 of 3 values (if server responds):

i) true ii) false iii) error

the main problem code new tab script in each of 3 if statements work should. however, last script opens results.aspx page not executing reason or another. script written executed if other code commented out. how should solve problem?

i tried replacing response.redirect("results.aspx") exeuctes , other 3 scripts never execute.

you should register these @ once, rather in 2 separate statements:

if (function.equals("larger50")) {       request req = new request();       string result = req.dorequest("function=" + function + "&num=" + number, "http://localhost:4000/handler.ashx");        string scriptval = "";        if (result.equals("true") || result.equals("true"))       {             scriptval = "window.open('http://localhost:4000/larger.aspx?num=" + number + "', '_newtab');";        }         if(result.equals("false") || result.equals("false"))        {             scriptval = "window.open('http://localhost:4000/smaller.aspx', '_newtab');";        }         if(result.equals("error") || result.equals("error"))        {             scriptval = "window.open('http://localhost:4000/errorpage.htm', '_newtab');";        }         session["result"] = result;         scriptval += "window.location.href = 'results.aspx';";         page.clientscript.registerstartupscript(page.gettype(), null, scriptval, true); }

see docs on clientscriptmanager.registerstartupscript, specifically:

a startup script uniquely identified key , type. scripts same key , type considered duplicates. 1 script given type , key pair can registered page. attempting register script registered not create duplicate of script.

in case, type , key same in both of scripts register.

you uniquely identify them key, , register them separately. have keep in mind order of execution not guaranteed:

the script blocks not guaranteed output in order registered.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
