  • How to prevent CAST errors on SSIS ?

    - by manitra
    Hello, The question Is it possible to ask SSIS to cast a value and return NULL in case the cast is not allowed instead of throwing an error ? My environment I'm using Visual Studio 2005 and Sql Server 2005 on Windows Server 2003. The general context Just in case you're curious, here is my use case. I have to store data coming from somewhere in a generic table (key/value structure with history) witch contains some sort of value that can be strings, numbers or dates. The structure is something like this : table Values { Id int, Date datetime, -- for history Key nvarchar(50) not null, Value nvarchar(50), DateValue datetime, NumberValue numeric(19,9) } I want to put the raw value in the Value column and try to put the same value in the DateValue column when i'm able to cast it to Datetime in the NumberValue column when i'm able to cast it to a number Those two typed columns would make all sort of aggregation and manipulation much easier and faster later. That's it, now you know why i'm asking this strange question. ============ Thanks in advance for your help.

  • How can I use a value of JSP in Javascript code?

    - by novellino
    Hello, I have a list of elements, each of them appeared in my page through jsp. So I have this: <div id="title"><%= list.get(ind).getTitle() %></div> When I display the elements, as this tag is in for loop, I get everything right. Now I what to place a button for deleting each of this elements. What I have done is: <input type="submit" name="submit" onclick="deleteNewsFunction();" id="submit_btn"/> In the deleteNewsFunction() I just want to print the data. <script> function deleteNewsFunction(){ var item = $('#title').val(); alert(item); } </script> The problem is that the title var gets always the first item even if I am clicking on the button of the second item. I was thinking that maybe a solution is to add the "list.get(ind).getTitle()" as a parameter in the function like deleteNewsFunction(<%=list.get(ind).getTitle()%) but then it did not work at all. Does anyone know how to help me? Thanks a lot!

  • Jquery returns index -1 always

    - by jfreak53
    This is my index code that I use to return the buttons parent div's index: j('#optionform').index( j(this).parent() ) I'm trying to find out the DIV index of the button clicked, so I can remove the DIV. The HTML layout is like so: <form id="optionform" onsubmit="return false;"> <label><input type="checkbox" id="s_name" value="s_name"> Survey Name </label> <label><input type="checkbox" id="s_type" value="s_type"> Survey Type </label><br> Filter Results:<br> <div id="template" style="display: none;"> Column: <select id="fcolumn[]"> <option></option> <option value="s_name">Survey Name</option> <option value="s_type">Survey Type</option> </select><br> Filter Type: <select id="ftype[]"> <option></option> <option value="=">Equals</option> <option value="LIKE">Like</option> </select><br> Filter content: <input type="text" id="fcontent[]"><br> <img src="images/add.png" width="32px" onclick="addTemp(); return false;"> <img src="images/delete.png" width="32px" onclick="alert(j(this).attr('src')); remTemp(j('#optionform').index( j(this).parent() )); return false;"> </div> <div class="template" style="display: block;"> Column: <select id="fcolumn[]"> <option></option> <option value="s_name">Survey Name</option> <option value="s_type">Survey Type</option> </select><br> Filter Type: <select id="ftype[]"> <option></option> <option value="=">Equals</option> <option value="LIKE">Like</option> </select><br> Filter content: <input type="text" id="fcontent[]"><br> <img src="images/add.png" width="32px" onclick="addTemp(); return false;"> <img src="images/delete.png" width="32px" onclick="alert(j(this).attr('src')); remTemp(j('#optionform').index( j(this).parent() )); return false;"> </div> <div class="template" style="display: block;"> Column: <select id="fcolumn[]"> <option></option> <option value="s_name">Survey Name</option> <option value="s_type">Survey Type</option> </select><br> Filter Type: <select id="ftype[]"> <option></option> <option value="=">Equals</option> <option value="LIKE">Like</option> </select><br> Filter content: <input type="text" id="fcontent[]"><br> <img src="images/add.png" width="32px" onclick="addTemp(); return false;"> <img src="images/delete.png" width="32px" onclick="alert(j(this).attr('src')); remTemp(j('#optionform').index( j(this).parent() )); return false;"> </div> </form> But it always returns -1 in the index.

  • Should we avoid to use Object as the input parameter/ output value of a method?

    - by developer.cyrus
    Take Java syntax as an example, though the question itself is language independent. If the following snippet takes an object MyAbstractEmailTemplate as input argument in the method setTemplate, the class MyGateway will then become tightly-coupled with the object MyAbstractEmailTemplate, which lessens the re-usability of the class MyGateway. A compromise is to use dependency-injection to ease the instantiation of MyAbstractEmailTemplate. This might solve the coupling problem to some extent, but the interface is still rigid, hardly providing enough ?exibility to other developers/ applications. So if we only use primitive data type (or even plain XML in web service) as the input/ output of a method, it seems the coupling problem no longer exists. So what do you think? public class MyGateway { protected MyAbstractEmailTemplate template; publoc void setTemplate(MyAbstractEmailTemplate template) { this.template = template; } }

  • Generics limitation, or lack of skillz ?

    - by Two Shoes
    I want to define the following class as such: public class CollectionAttribute<E extends Collection<T>> { private String name; private E value; public CollectionAttribute(String name, E value) { this.name = name; this.value = value; } public E getValue() { return value; } public void addValue(T value) { value.add(T); } } This won't compile (cannot resolve symbol T). If I replace the class declaration with the following: public class CollectionAttribute<E extends Collection<?>> Then I can't reference the parametrized type of the collection. Am I missing something or have I reached a limitation with generics in Java ?

  • how to avoid temporaries when copying weakly typed object

    - by Truncheon
    Hi. I'm writing a series classes that inherit from a base class using virtual. They are INT, FLOAT and STRING objects that I want to use in a scripting language. I'm trying to implement weak typing, but I don't want STRING objects to return copies of themselves when used in the following way (instead I would prefer to have a reference returned which can be used in copying): a = "hello "; b = "world"; c = a + b; I have written the following code as a mock example: #include <iostream> #include <string> #include <cstdio> #include <cstdlib> std::string dummy("<int object cannot return string reference>"); struct BaseImpl { virtual bool is_string() = 0; virtual int get_int() = 0; virtual std::string get_string_copy() = 0; virtual std::string const& get_string_ref() = 0; }; struct INT : BaseImpl { int value; INT(int i = 0) : value(i) { std::cout << "constructor called\n"; } INT(BaseImpl& that) : value(that.get_int()) { std::cout << "copy constructor called\n"; } bool is_string() { return false; } int get_int() { return value; } std::string get_string_copy() { char buf[33]; sprintf(buf, "%i", value); return buf; } std::string const& get_string_ref() { return dummy; } }; struct STRING : BaseImpl { std::string value; STRING(std::string s = "") : value(s) { std::cout << "constructor called\n"; } STRING(BaseImpl& that) { if (that.is_string()) value = that.get_string_ref(); else value = that.get_string_copy(); std::cout << "copy constructor called\n"; } bool is_string() { return true; } int get_int() { return atoi(value.c_str()); } std::string get_string_copy() { return value; } std::string const& get_string_ref() { return value; } }; struct Base { BaseImpl* impl; Base(BaseImpl* p = 0) : impl(p) {} ~Base() { delete impl; } }; int main() { Base b1(new INT(1)); Base b2(new STRING("Hello world")); Base b3(new INT(*b1.impl)); Base b4(new STRING(*b2.impl)); std::cout << "\n"; std::cout << b1.impl->get_int() << "\n"; std::cout << b2.impl->get_int() << "\n"; std::cout << b3.impl->get_int() << "\n"; std::cout << b4.impl->get_int() << "\n"; std::cout << "\n"; std::cout << b1.impl->get_string_ref() << "\n"; std::cout << b2.impl->get_string_ref() << "\n"; std::cout << b3.impl->get_string_ref() << "\n"; std::cout << b4.impl->get_string_ref() << "\n"; std::cout << "\n"; std::cout << b1.impl->get_string_copy() << "\n"; std::cout << b2.impl->get_string_copy() << "\n"; std::cout << b3.impl->get_string_copy() << "\n"; std::cout << b4.impl->get_string_copy() << "\n"; return 0; } It was necessary to add an if check in the STRING class to determine whether its safe to request a reference instead of a copy: Script code: a = "test"; b = a; c = 1; d = "" + c; /* not safe to request reference by standard */ C++ code: STRING(BaseImpl& that) { if (that.is_string()) value = that.get_string_ref(); else value = that.get_string_copy(); std::cout << "copy constructor called\n"; } If was hoping there's a way of moving that if check into compile time, rather than run time.

  • How do I rewrite a request by hostname unless it is a specified value?

    - by Tim
    My app will have a regular domain - let's say example.com - which will have information about logging in, signing up, etc. It will also host numerous other domains dynamically. My app serves the webpage for these at http://example.com/site/foobar.com/ So, I need to redirect all requests where the hostname is not example.com to /site/[hostname]/ I'm writing this in Django and hosting with Apache. How do I set up a rewrite rule to do this? The user must not know they are on any other site but foobar.com and if the user browses to foobar.com/something - the URL must be rewritten to /site/foobar.com/something

  • What jQuery is triggered when a user selects a "drop down list" option

    - by Ankur
    I want to display a different form for different selections of this drop down list: <label> <select name="type" id="type"> <option value="object" selected="selected">Object</option> <option value="number">Number</option> <option value="text">Text</option> <option value="date">Date</option> <option value="time">Time</option> <option value="geo">Geospatial</option> <option value="currency">Currency</option> </select> </label> What would be the jQuery event that is triggered when a user selects one of these options. Would the .click() event be triggered in this case as well?

  • Drawing up a session value within SQL query? PHP and MySQL

    - by Derek
    Hi, on one of my web pages I want my manager user to view all activities assigned to them (personally). In order to do this, I need something like this: $sql = "SELECT * FROM activities WHERE manager = $_SESSION['SESS_FULLNAME']"; Now obviously this syntax is all wrong, but because I am new to this stuff, is there a way I can call up the full name from the user's session within a query? This is so that when I call up the database values to be displayed within the web page, only the activities for the manager who is logged in is displayed. For example, the activities table has a manager column of a full name entry. Any help is much appreciated. Thanks.

  • What's the best way to replace the first letter of a string in Java?

    - by froadie
    I'm trying to convert the first letter of a string to lowercase. I know there's a capitalize method, but I want to accomplish the opposite. This is the code I used: value.substring(0,1).toLowerCase() + value.substring(1) Effective, but feels a bit manual. Are there any other ways to do it? Any better ways? Any Java string functions that do it for you? I was thinking of using something like a replace function, but Java's replace doesn't accept an index as a parameter. You have to pass the actual character/substring. Another way I can think of doing it is something like: value.replaceFirst(value.charAt(0), value.charAt(0).toLowerCase()) Except that replaceFirst expects 2 strings, so the value.charAt(0)s would probably need to be replaced with value.substring(0,1)s. Is this any better? Does it matter? Is there any standard way to do this?

  • is it some bug in firefox or jquery or i doing something wrong?

    - by llamerr
    I want to change hidden input value on div click, so i do following: $('#gallery').click(function(){ if ($('input[name=isgallery]').attr('value') == '0') { $('input[name=isgallery]').attr('value', '1') } else { $('input[name=isgallery]').attr('value', '0') } $('#filterform').attr('action',$('#filterform').attr('act')); alert('ok'); $('#filterform').submit(); } ); when it equals 0 i change it to 1 and otherwise but it did not work and following code works: $('#gallery').click(function(){ if ($('input[name=isgallery]').attr('value') == '0') { $('input[name=isgallery]').attr('value', '0') } else { $('input[name=isgallery]').attr('value', '1') } $('#filterform').attr('action',$('#filterform').attr('act')); alert('ok'); $('#filterform').submit(); } ); and also, when i delete the function at all it still works and form submits maybe i have one more handler for this div, but i can't find one you can check it on http://www.4block.org/en/museum/posters and click "gallery view" on top-right

  • How to increment a value using a C-Preprocessor?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • does a git repository have its own local value for core.autocrlf that overrides the global one?

    - by Warren P
    As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

  • How to break out of a loop depending on a CheckBox Checked value while the loop is running?

    - by Rayner Vaz
    Lets say I want to call a function repeatedly if the user selects a CheckBox named "repeat" but the calls to the function should stop as soon as the user 'unchecks' the CheckBox. I tried using the 'Checked', 'Click' and 'Tap' event of the CheckBox but once the loop starts, it does not sense any changes in the checkbox's state. I even tried using a loop inside another button's _Click method, but then that creates a lock on the Button's 'pressed' state. Any ideas/alternate suggestions?

  • How to write function where argument is type but not typed value?

    - by ssp
    I want to convert a string representations of few dozen enum types to enum values. It's easy to convert string to concrete type: Enum.Parse(typeof<FontStyle>,"Bold") |> unbox<FontStyle> but for now i want to write function where type and string are parameters. The best one i can write is: > let s2e (_: 'a) s = Enum.Parse(typeof<'a>,s) |> unbox<'a>;; val s2e : 'a -> string -> 'a > s2e FontStyle.Regular "Bold";; val it : FontStyle = Bold Is there any option to write something like this but with type itself as first argument?

  • Is it possible to use an incremental value within a variable name whilst declaring it within a loop?

    - by Jack
    Hi, I'm creating function which will read different XML files each time that will contain different amounts of the same nodes. I have already created a loop which stores the ID of each node into an array, and now I want to create variables for each array member which store attributes of the node with each ID. Because the number of nodes will be different for every XML document my function reads, I cannot manually assign variables for the attributes of each node ID not knowing how many to assign, so I have created a loop which runs specific to the number of items I have stored in the array. Inside this loop I was hoping to have something like: for (i=0; i<array.length; i++) { var ID + i + width = exampleheight var ID + i + height = exampleheight } I know this doesn't work, but was trying to outline what I am looking to find out. Is it possible to use some kind of variable or random number when declaring a variable?
