I have a form.The user enter the data ,the data will be stored in the data base.
Now,using phpmysql,i need to display the whole data present in db to front end.The user will click a particular thing and make some modifications and if,he press update the data should get into database.
Give me a snippet

What is the easiest and safest way to retrieve XmlHttpRequest object that works across all browsers? Without any extra libraries. Is there a codesnippet you use often?
P.S. I know there are tons of examples on the net, but this is precisely the reason I am asking: there are too many different examples, and I just want something simple and proven to work.
var obj = document.getElementById("header");
Given the above codesnippet, I should be able to wire event handlers. For example, I can wire onMouseDown to the mouse down event, the issue is that Visual Studio does not display this in the Intellisense.
I've tried this on both a standalone Javascript file, as well as an MVC project to no luck.
Is there anything I'm doing wrong - or is there a way to resolve this?
I'm working in the JNI Invocation API, calling into Java from C. I have some upfront initialization to cache 30+ Java classes into global references. The results of FindClass are passed into NewGlobalRef to acquire a global reference to the class. I'm caching these class variables to reuse them later. I have 30+ global references to classes (and 30+ global methodIDs for the class constructors).
In the following sample, I've removed exception handling as well as JNI invocation for the purpose of shortening the codesnippet. My working code has exception checks after every JNI call and I'm running with -Xcheck:jni. Here's the snippet:
jclass aClass;
jclass bClass;
jmethodID aCtor;
jmethodID bCtor;
void getGlobalRef(const char* clazz, jclass* globalClass)
{
jclass local = (*jenv)->FindClass(jenv,clazz);
if (local)
{
*globalClass = (jclass) (*jenv)->NewGlobalRef(jenv,local);
(*jenv)->DeleteLocalRef(jenv,local);
}
}
methodID getMethodID(jclass clazz, const char* method, const char* sig)
{
return (*jenv)->GetMethodID(jenv,clazz,method,sig);
}
void initializeJNI()
{
getGlobalRef("MyProj/Testclass1", &aclass);
getGlobalRef("MyProj/Testclass2", &bclass);
.
.
aCtor = getMethodID(aclass,"<init>","()V");
bCtor = getMethodID(bclass,"<init>","(I)V");
}
The initializeJNI() function sets the global references for jclasses and method IDs for constructors as well as some jfieldID's and some initialization of C data structures.
After initialization, when I call into a JNI function using some of the cached jclasses and ctor jmethodIDs, I get a bad global or local reference calling reported from the -Xcheck:jni.
In gdb, I break at the last line of initializeJNI(), and print all jclasses and jmethodIDs and the ones causing problems look to have been turned into garbage or garbage-collected (i.e. 0x00 or 0x06). Is it possible for global references to be gc'ed?
Any suggestions?
I have a small snippet of code that does some work on a cookie on every page load.
(It's for affiliate tracking if you want to know why)
Where do I put this so it runs every every time a drupal page is loaded
So here's a snippet of my code:
struct dv_nexthop_cost_pair
{
unsigned short nexthop;
unsigned int cost;
};
map<unsigned short, vector<struct dv_nexthop_cost_pair> > dv;
I'm getting the following compiler error:
error: ISO C++ forbids declaration of `map' with no type
What's the proper way to declare this?
hi folks, i'm using ip*works for download newsgroup message and insert them into a database... ipworks is "comfortable" to use because it automatically split nntp data return into different object (or variable). So i've "author" "date" "topic" "messagge" already splitted to my use.
However ipworks isn't free and it cost a lot for my use.. so i'm asking you some component or codesnippet to use to download and "manage" nntp messagges.
Thanks in advance and regards!
Hi,
Dll best practices document from Microsoft available Here recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the codesnippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx".
Is it a violation of Dll Best Practices or ok to use in MFC extension DLL?
thanks
Take a look that the following code snippet:
A a = null
try {
a = new A();
} finally {
a.foo(); // What happens at this point?
}
Suppose A's constructor throws a runtime exception. At the marked line, am I always guaranteed to get a NullPointerException, or foo() will get invoked on a half constructed instance?
Hello, I am getting a compile error, saying that the copy constructor of the scoped_ptr is private with the following code snippet:
class a {};
struct s
{
boost::scoped_ptr<a> p;
};
BOOST_PYTHON_MODULE( module )
{
class_<s>( "s" );
}
This example works with a shared_ptr though. It would be nice, if anyone knows the answer. Thanks
Hello,
I'm creating a java web application runing on a Tomcat server.
One of the functions fill in a StringBuffer variable with data.
At the end, I would like to propose the user to download the generated content packaged in a text file. This without having to store the file on the server.
I've been searching for a codesnippet but couldn't find anything corresponding ...
I hope I've been clear enough on my problem.
Thanks in advance,
In my snippet below, the non-capturing group "(?:aaa)" should be ignored in matching result,
so the result should be "_bbb" only.
However, I get "aaa_bbb" in matching result; only when I specify group(2) does it show "_bbb".
import re
string1 = "aaa_bbb"
print(re.match(r"(?:aaa)(_bbb)", string1).group())
>>> aaa_bbb
Hi there,
I want to have a function in my zsh for faster accessing my todo-files. It should look inside the folder ~/tasks where i put my todo-lists and stuff. Now i want to type task p and when I hit tab, it should use the files in that directory for autocompletition. Can anyone point me some direction? Or share some snippet to work with?
Thanks
I have been writing specs for controllers and models, but I have never written a helper spec. I have no idea where I start.
I have the following snippet in application_helper.rb
def title(page_title)
content_for(:title) { page_title }
end
How should I write a helper spec on the code?
Also if there's any open-source Rails app to show good helper testing/specing, do let me know.
I am kind of repeating this question because mostly due to my own ignorance, I could not fully understand the innards.
Given this HTML snippet
<td valign=top class="tim_new"><a href="/stocks/company_info/pricechart.php?sc_did=MI42" class="tim_new">3M India</a></td> <td class="tim_new" valign=top><a href='/stocks/marketstats/indcomp.php?optex=NSE&indcode=Diversified' class=tim>Diversified</a></td>
How does this XPATH //a[@class='tim_new'] differentiate between line 1 and line 2.
I can able to create Wired Sphere using GLUT ,Now i want to bind one texture image on the sphere,can any one tell me how to do it.If u can pls provide me some code snippet?
regards,
s.kumaran.
as my snippet below, the non-capturing group "(?:aaa)" should be ignored in matching result,
so the result should be "_bbb" only.
however, I get "aaa_bbb" in matching result
only when I specify group(2) does it show "_bbb".
import re
string1 = "aaa_bbb"
print(re.match(r"(?:aaa)(_bbb)", string1).group())

Hi ,
Please give me a real time simple example for the below questions :
Where to use interface rather abstract class
Where to use abstract class rather interface
I need codesnippet for both .
Which takes low memory and which performs well . Do I need to consider the design aspect also?
What is the conceptual difference not the syntactical difference .
Would someone please explain to me what the below paragraph means? This is a snippet from "Design Patterns: Elements of Reusable OO software"
Part of an object's interface may be characterized by one type, and other parts by other types. Two objects of the same type need only share parts of their interfaces. Interfaces can contain other interfaces as subsets. - Design Patterns - Elements of Reusable OO software, pg 13
Hi all,
If I have .flv files on my server at some location like http://www.example.com/archive/test.flv. In HTML page how can I tell the browser to use Flash player to play this video like youtube videos are played.
Can someone tell me how to do this?
Regards,
Microkernel
PS: I am noober than noob in web dev, so please give some codesnippet or answers that beginners like me can understand. Thank you
I'm trying to make my monotouch app continue playing when the device is locked, I found this snippet in ObjC, was wondering if mt already has bindings for it or not.
AudioSessionInitialize (NULL,NULL,interruptionListenerCallback,self);
UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
