Hi,
I have series of records in a table called 'hits' and each record has the current_timestamp (ie. 2010-04-30 10:11:30) in a column called 'current_time'.
What I would like to do is query these records and return only the records from the current month. I cannot seem to get this to work.
I have tried a range of queries that don't work such as -
Select * FROM hits WHERE MONTH(FROM_UNIXTIME(current_time)) = 4
I don't know if I am even on the right lines!
Can anyone point me in the right direction?
Cheers.
Hi everyone.
I'm writing a class, and this doubt came up. Is this undef. behaviour? On the other hand, I'm not sure its recommended, or if its a good practice. Is it one if I ensure no exceptions to be thrown in the init function?
//c.h
class C{
float vx,vy;
friend void init(C& c);
public:
C();
};
//c.cpp
C::C()
{
init(*this);
}
void init(C& c) //throws() to ensure no exceptions ?
{
c.vx = 0;
c.vy = 0;
}
Thanks in advance
Hi I need some sample MS SQL Employee database with data such as id, surname, name, age, adress etc. It must be quite big, I search with google, but I don't find any good sample.
Can any body help ?
Hello SO;
I've been fighting with this problem all day and am just about at my wit's end.
I have an XML file in which certain portions of data are stored as escaped text but are themselves well-formed XML. I want to convert the whole hierarchy in this text node to a node-set and extract the data therein. No combination of variables and functions I can think of works.
The way I'd expect it to work would be:
<xsl:variable name="a" select="InnerXML">
<xsl:for-each select="exsl:node-set($a)/*">
'do something
</xsl:for-each>
The input element InnerXML contains text of the form
<root><element a>text</element a><element b><element c/><element d>text</element d></element b></root>
but that doesn't really matter. I just want to navigate the xml like a normal node-set.
Where am I going wrong?
To begin with, I just can say that I have always been programming by my own. I use php mostly. So, can you explain me why I should learn Zend Framework or other framework? Why just don't write a pure code by own?
Hi,
Does anyone know a library to compare addresses in Java ?
Something that would give equality on addresses, written in different ways.
For example, it should recognize that
"22 Acacia Avenue" and "22 acacia av."
is the same address.
Of course, this can escalate a lot, that's why i'm asking.
Thanks in advance.
When I use the annotation:
@XmlRootElement(name="RootElement", namespace="namespace")
class RootElement {
to create xml file from java, it creates the root element as:
<ns2:RootElement xmlns:ns2="namespace">
but I wanted to create without the "ns2", like:
<RootElement xmlns="namespace">
Any idea how to fix it?
Reletad link (example I used to create the xml):
http://www.java2s.com/Code/JavaAPI/javax.xml.bind.annotation/XmlRootElementname.htm
I need encrypt data using exactly the PKCS#1 V2.0 encryption method (defined in item 7.2.1 of the PKCS#1V2 specification).
Is it already implemented for Java?
I'm thinking in something like just pass a parameter to javax.crypto.Cipher specifying "PKCS#1V2", I wonder if there is something like this?
I have a class with a methodcalled GetEnemiesLua. I have bound this class to lua using SWIG, and I can call this method using my lua code.
I am trying to get the method to return a lua table of objects.
Here is my current code:
void CSpringGame::GetEnemiesLua(){
std::vector<springai::Unit*> enemies = callback->GetEnemyUnits();
if( enemies.empty()){
lua_pushnil(ai->L);
return;
} else{
lua_newtable(ai->L);
int top = lua_gettop(ai->L);
int index = 1;
for (std::vector<springai::Unit*>::iterator it = enemies.begin(); it != enemies.end(); ++it) {
//key
lua_pushinteger(ai->L,index);//lua_pushstring(L, key);
//value
CSpringUnit* unit = new CSpringUnit(callback,*it,this);
ai->PushIUnit(unit);
lua_settable(ai->L, -3);
++index;
}
::lua_pushvalue(ai->L,-1);
}
}
PushIUnit is as follows:
void CTestAI::PushIUnit(IUnit* unit){
SWIG_NewPointerObj(L,unit,SWIGTYPE_p_IUnit,1);
}
To test this I have the following code:
t = game:GetEnemiesLua()
if t == nil then
game:SendToConsole("t is nil! ")
end
The result is always 't is nil', despite this being incorrect. I have put breakpoints in the code and it is indeed going over the loop, rather than doing lua_pushnil.
So how do I make my method return a table when called via lua?
I'm sure I'm simply overlooking something in the Facebook API docs. Basically, after I've loaded the FB Graph, I need to know if the session is active... I cannot simply assume they're logged out and simply re-render if they're logged in once the 'auth.statusChange' event is triggered. I need to know right off the bat.
Below is the code that I've used. Most importantly the FB.getLoginStatus/getAuthResponse/getAccessToken don't work like I'd expect; essentially where it indicates, when invoked, whether they're logged in or out.
(function(d) {
// Create fb-root
var fb_root = document.createElement('div');
fb_root.id = "fb-root";
document.getElementsByTagName('body')[0].appendChild( fb_root );
// Load FB Async
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
// App config-data
var config = {
appId : XXXX,
cookie: true,
status: true,
frictionlessRequests: true
};
window.fbAsyncInit = function() {
// This won't work.
// I can't assume they're logged out and rely on this to tell me they're logged in.
FB.Event.subscribe('auth.statusChange', function(response) {});
// Init
FB.init(config);
// These do not inidicate if the user is logged out :(
FB.getLoginStatus(function(response) { });
FB.getAuthResponse(function(response) { });
FB.getAccessToken(function(response) { });
};
}(document));
Any help is much appreciated. :)
Oftentimes data structures' valid initialization is to set all members to zero. Even when programming in C++, one may need to interface with an external API for which this is the case.
Is there any practical difference between:
some_struct s;
memset(s, 0, sizeof(s));
and simply
some_struct s = { 0 };
Do folks find themselves using both, with a method for choosing which is more appropriate for a given application?
For myself, as mostly a C++ programmer who doesn't use memset much, I'm never certain of the function signature so I find the second example is just easier to use in addition to being less typing, more compact, and maybe even more obvious since it says "this object is initialized to zero" right in the declaration rather than waiting for the next line of code and seeing, "oh, this object is zero initialized."
When creating classes and structs in C++ I tend to use initialization lists; I'm curious about folks thoughts on the two "C style" initializations above rather than a comparison against what is available in C++ since I suspect many of us interface with C libraries even if we code mostly in C++ ourselves.
I am taking over someone elses code. What are some good ways to learn what that programmer did as quickly as possible? I have been running it, stepping through it and looking at the callstack. What else can I do?
Sorry I forgot to mention, but there is little documentation and I have been trying to fix simple problems. Thanks!
I'm in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind.
Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project.
Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class?
I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?
Say I somehow got an object reference from an other class:
Object myObj = anObject;
Now I can get the class of this object:
Class objClass = myObj.getClass();
Now, I can get all constructors of this class:
Constructor[] constructors = objClass.getConstructors();
Now, I can loop every constructor:
if (constructors.length > 0)
{
for (int i = 0; i < constructors.length; i++)
{
System.out.println(constructors[i]);
}
}
This is already giving me a good summary of the constructor, for example a constructor public Test(String paramName) is shown as public Test(java.lang.String)
Instead of giving me the class type however, I want to get the name of the parameter.. in this case "paramName". How would I do that? I tried the following without success:
if (constructors.length > 0)
{
for (int iCon = 0; iCon < constructors.length; iCon++)
{
Class[] params = constructors[iCon].getParameterTypes();
if (params.length > 0)
{
for (int iPar = 0; iPar < params.length; iPar++)
{
Field fields[] = params[iPar].getDeclaredFields();
for (int iFields = 0; iFields < fields.length; iFields++)
{
String fieldName = fields[i].getName();
System.out.println(fieldName);
}
}
}
}
}
Unfortunately, this is not giving me the expected result. Could anyone tell me how I should do this or what I am doing wrong? Thanks!
I'm really not sure what else to say about this:
Random r = new Random();
class SomeClass {
public SomeClass(){
new SomeClass(r.nextInt(5));
}
public SomeClass(int i){
...
Throws a NullPointerException where r.nextInt(5) is called. Any ideas?

I know how to reboot machines remotely, so that's the easy part. However, the complexity of the issue is trying to setup the following. I'd like to control machines on a network for after-hours use such that when users logoff and go home, or shutdown their computers, whatever, python or some combination of python + windows could restart their machines (for cleanliness) and automatically login, running a process for the night, then in the morning, stop said process and restart the machine so the user could easily login like normal.
I've looked around, haven't had too terribly much luck, though it looks like one could do it with a changing of the registry. That sounds like a rough idea though, modifying the registry on a per-day basis. Is there an easier way?
I'm trying to add a button onclick event to a button tag when I load my Fancybox popup using the following code:
var processOrder = function(id) {
$('#processPopupLink').fancybox({
'hideOnContentClick': false,
'frameWidth': 850,
'frameHeight': 695
}).click();
$('#processComplete').click(function() {
alert('debug');
});
}
However, it's not showing the message box when I click the button, I have no idea why it is not working, any help would be appreciated.
I have defined an object in 3D space with position, rotation and scale values (all defined as 3D vectors). It also has upwards and forwards direction vectors. When I rotate the object, I need these direction vectors to rotate with it.
Assuming my up vector is (0, 1, 0) and my forwards vector is (0, 0, 1) at zero rotation, how might I achieve this?
Hello SO;
I'm trying to convert xml elements whose content is a csv list of identifiers, the exact form doesn't matter. I want to exclude every item that contains the character "/". The best I've come up with is
translate(./someElement, ",*/*", "")
but this has at least two problems; I'm pretty sure that xsl doesn't accept wildcards, and "," is an illegal character in xpaths.
Is there a straightforward way to do this sort of thing?
Hi,
I have a string in PHP for example $string = "Blabla [word]";
I would like to filter the word between the '[' brackets.
The result should be like this $substring = "word";
thanks
Switching aged 2003 SRV to 2008 caused my Asp.net 2 application fail: The application is no more loading the required library DLL from /bin/ folder anymore.
What should I change in my code or web.config to make this webapp load OK also in new 2008 server?
Now I receive this error when I access the application: This type is in IMPORTS ( Dll ).
