I need to make a questionary(test) from users then write their answers in a database, I want to make a test on a web page. Please, if somebody know please help me.
I forgot to write void parameter but it works the i put void it gives error
it lets this:
print(int size,int table[size][size]){
int i,j;
printf("-------TABLE-------\n");
for(i = 0;i
it says"previos implicit declaration was here " (means the call in main)
void print(int size,int table[size][size]){
int i,j;
printf("-------TABLE-------\n");
for(i = 0;i
I have created a .NET user control with an ActiveX interface. It works well.
Now, I want to be able to read and write from the property bag for the ActiveX interface.
How would I do this?
I am writing a functor F which takes function of type void (*func)(T) and func's argument arg. Then functor F calls func with arg. I would like F not to copy arg, just to pass it as reference. But then I cannot simply write "void F(void (*func)(T), T&)" because T could be a reference. So I am trying to write a trait, which allows to get proper reference type of T:
T -> T&
T& -> T&
const T -> const T&
const T& -> const T&
I come up with something like this:
template<typename T>
struct type_op
{
typedef T& valid_ref_type;
};
template<typename T>
struct type_op<T&>
{
typedef typename type_op<T>::valid_ref_type valid_ref_type;
};
template<typename T>
struct type_op<const T>
{
typedef const T& valid_ref_type;
};
template<typename T>
struct type_op<const T&>
{
typedef const T& valid_ref_type;
};
Which doesn't work for example for
void a(int x) { std::cout << x << std::endl; }
F(&a, 7);
Giving error:
invalid initialization of non-const reference of type ‘int&’ from a temporary of type ‘int’ in passing argument 2 of ‘void f(void (*)(T), typename type_op::valid_ref_type) [with T = int]’
How to get this trait to work?
Hello,
i just asked a question few minutes ago which led me to this one :
I want to know if there is any chance to use only the back-end of wordpress ?
I mean,
link my admin interface to post news
link my visitor interface on my website to the wordpress news so the visitor can access the news
So the visitor never find out that i'm using wordpress to generate the news and handle their comments and write my news ?
Maybe it's possible but there is no point by doing so ?
Thank you
Hi I am having Netezza Database. I am querying the tables through DB visualiser. Since my table creation involves complex, I am interested to use procedures but I am unable to write it in DBvisualiser. I am confused whether the problem is with the tool that I use or in Netezza? Please advice
Hi,
In QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's. In other words all vertex's which have somewhere under them (on the way to the leaf nodes) one or more of the vertexs input. So if the vertexs were Nodes, and the edges were a depends on relationship, find all nodes that would be impacted by a given set of nodes.
If not how hard is it to write one's own algorithms?
One of job interview questions on C pointer here is the following: what is null pointer assignment error?
I've googled for a while and don't see any reasonable explanation. What is that? Trying to write through a null pointer? Something architecture- or environment-specific? What exactly is that error?
I've seen questions to prefix zeros here in SO. But not the other way !!
Can you guys suggest me how to remove the leading zeros in alphanumeric text. Are there any built-in APIs or do I need to write a method to trim the leading zero's?
Example:
01234 converts to 1234
0001234a converts to 1234a
001234-a converts to 1234-a
101234 remains as 101234
2509398 remains as 2509398
123z remains as 123z
000002829839 converts to 2829839
In my app the user generates text content. I want to enable the user to launch the Mail application, which then should contain a specified subject and message body. Like: You write a poem in my app and then want to send it to your new girlfriend. So you tap a mail icon and the Mail app opens, containing already an subject and message body with your poem inside.
Someone said there is a kind of URL mechanism for that?
I've been searching and i can't find any ff addons or javascript for finding unused css in ajax apps.
dust-me selectors
can do a site-crawl, but i'm looking for something that examines loaded-in content...
I'd like something where i can press 'record' and then make a load of clicks which will check off the used selectors, and hoping to find an existing one rather than try to write my own with jquery!
I have 2 dimensional table in file, which look like this:
11, 12, 13, 14, 15
21, 22, 23, 24, 25
I want it to be imported in 2 dimensional array. I wrote this code:
INTEGER :: SMALL(10)
DO I = 1, 3
READ(UNIT=10, FMT='(5I4)') SMALL
WRITE(UNIT=*, FMT='(6X,5I4)') SMALL
ENDDO
But it imports everything in one dimensional array.
I was wondering, is there some type of disc ID i can use to search in my database to see if that disc is has been scanned or not? All disc were created by me typically burnt on windows.
-edit- I could compare write time and volume label to see if the disc has been scanned but i notice if i put in certain commercial disc that fields are blank or wrong causing many false positives (i once had the time set to the future, i dont know if people want to archive the contents of files on a commercial disc in my app).
For a large application written in C++ using Visual Studio 6, what is the best way to move into the modern era?
I'd like to take an incremental approach where we slowly move portions of the code and write new features into C# for example and compile that into a library or dll that can be referenced from the legacy application.
Is this possible and what is the best way to do it?
Hi,
I need to create a program that creates another program but not a compiler though.
For example,
I write a program that accepts a string input from the user. Let's say user enter "Pluto". This program should then create a separate .exe that says "Hello Pluto" when executed.
How can I do this? If you could give example in C# and Windows Forms, it's better.
Thanks.
I would like to write my own LDAP client under Linux, specific to our local environment. Most probably I will use QT4 to provide a shiny frontend without much hassle.
I found that there seems to be no standard C++ library for this. OpenLDAP provides a C API and there should also be a C++ API (experimental?) somewhere..
Do I need to use the C stuff or is there a C++ API out there worth of recommendation?
I frequently see python code similar to
for line in open(filename):
do_something(line)
When does filename get closed with this code?
Would it be better to write
with open(filename) as f:
for line in f.readlines():
do_something(line)
What's a good way to keep counting up infinitely? I'm trying to write a condition that will keep going until there's no value in a database, so it's going to iterate from 0, up to theoretically infinity (inside a try block, of course).
How would I count upwards infinitely? Or should I use something else?
I am looking for something similar to i++ in other languages, where it keeps iterating until failure.
Hi all, I'm trying to write a bit of jquery which finds all h2 tags inside a div (.content), then appends each one into another div (.intro).
So far I have this:
var h2 = $(".content").find("h2");
$(h2).each(function() {
$(this).append(".intro");
});
But it's not working.. if someone could help me out, that'd be great :)

has anyone had experience writing AT commands?
In all examples I can find as well as the automatically generated code i Visual Studio, events are set using the following code:
button1.Click += new System.EventHandler(this.button1_Click);
But I can also write it visually cleaner by omitting the constructor wrapper:
button1.Click += this.button1_Click;
Which also compile fine.
What is the difference between these two?
And why is the first one mostly used/preferred?
For example,
the start date = '20100530' and
the end date = '20100602'
How can I write a SQL to display the below result?

I was wondering how to make a python script portable to both linux and windows?
One problem I see is shebang. How to write the shebang so that the script can be run on both windows and linux?
Are there other problems besides shebang that I should know?
Is the solution same for perl script?
Thanks and regards!
