Text output file not instantiated -

-

I have two newbie questions. I am trying to bring data from an array into the text file on vhdl . Even though referring to many online guides to do this, I've always come up with the "file does not exist" any suggestions on what's going wrong?

Secondly, when I try to use the array sign below as an argument for the task of writing, then it gives an error that I have no continuous data form of an operand How can i use The unit is Top_Module Port (CLC: STD_LOGIC); Finally Top_Module; The behavior type of the architecture Top_Module array_1 is the array (0 to 127) integer range of -112 to 127; Signal sample_1: array_1: = (104, 40, -40, -104, -128, -104, -40,40,104,127,104,40,40, -4); Constants: std_logic_vector (3 below): = "0111"; Initial Process (CLK) - The process to write output to "* .txt" file file result_file: text "fft_output.txt" is out; Outline of the variable: line; Constant tmp_fft: integer: = 0; Then start (clk'event and clk = '1')) then --tmp_fft: = to_integer (signed (sample_1)); Write (outline, one); WriteLine (result_file, outline); end if; end process; The file declaration VHDL 1987 syntax is, so try it instead: 

  file result_file: The text is open write_mode "fft_output.txt";   
 Your code does not show this, but I think that you would like the  std.textio  package:  
  library std; Use Std.textio.all;   
 In VHDL 2002, this package does not know how to try  line  to  std_logic_vector  in  (Framework, A) . So if you are using VHDL 2002, then the problem may be due to lens support in the  write  process for the problem  std_logic_vector .  
 The non-standard Synopsys package is available in most of the devices  std_logic_textio , and includes a writing function for  std_logic_vector . This package can be used with:  
  Library IEEE; Use ieee.std_logic_textio.all;   
 VHDL 2008 standard  std_logic_vector  has been added to write in the package, so that you can check whether you are a simulator Support for this feature has been used in VHDL 2008. Note that binary and hex output should be  bwrite  and  hwrite .  
 Also note that  write  and  textio  in general is not possible because it is on the  line  type Based, which is again a  access  type, similar to the pointer type in other languages, and it can not be synthesized. For the synthesis use the  slv_image  function in the north of David Conts.

php - PDO bindParam() fatal error -

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: < P> Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

java - Why my included JSP file won't get processed correctly? -

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it. First of all, I want the following index.jsp : & lt; Body & gt; Use all pages to be created. & Lt;% @ include file = "header.jsp"% & gt; & Lt; Hours / & gt; & Lt;% @ included file = "body.jsp"%> & Lt; Hours / & gt; & Lt;% @ include file = "footer.jsp"% & gt; & Lt; / Body & gt; And, in body.jsp , I should have it like this: & lt; Jsp: include page = "$ {Application_modul}"%> Where application_modul is an attribute defined in its controller: request.setAttribute ("application_modul", "USER_ACCOUNT \\ ' View_user_account.jsp "); This file can be found properly, but the processed JSP does
