I would like to assign a value in a class property dynamically (that is referring to it using a variable).
#Something like:
setPropValue($obj, $propName, $value);
I have a form page in PHP that reads a DBF, and conditionally converts it into a MySQL - extracting the data from an old, but still production accounting app. The conversion should be able to be actioned without user intervention, ie scripted from the web-host's command line on a cron job.
How can I get PHP to submit the form automatically when receiving variables at command line, like for instance a specific post variable? Every auto-submit I've found so far relied upon javascript, which would be useless at PHP command line.
hi guys,

The error is Incorrect syntax near '@count'.Can anybody help?
Please tell me what is difference
== if i write query directly in storedprocedure
== and write query in string variable and than run it in exec in stored procedure.
i am using ms sql server 2005
Could really use with some help here...
I've got a servlet that generates an XML string (relatively long) which I then pass to a javascript variable in a forwarded jsp file:
$(document).ready(function() {
...
var itXML = <% out.print((String)request.getAttribute("xml"));% ;
...
}
This seems to work just fine in Firefox but when I run the same project on IE8 I get a syntax error for this line.
Any Ideas?
Thanks!
One of my friends sent this code to me, saying it doesn't work as expected:
#include<stdio.h>
void main()
{
int a [10] ={23, 100, 20, 30, 25, 45, 40, 55, 43, 42};
int sizeOfInput = sizeof(a)/sizeof(int);
int b, outer, inner, c;
printf("Size is : %d \n", sizeOfInput);
printf("Values before bubble sort are : \n");
for ( b = 0; b < sizeOfInput; b++)
printf("%d\n", a[b]);
printf("End of values before bubble sort... \n");
for ( outer = sizeOfInput; outer > 0; outer-- )
{
for ( inner = 0 ; inner < outer ; inner++)
{
printf ( "Comparing positions: %d and %d\n",inner,inner+1);
if ( a[inner] > a[inner + 1] )
{
int tmp = a[inner];
a[inner] = a [inner+1];
a[inner+1] = tmp;
}
}
printf ( "Bubble sort total array size after inner loop is %d :\n",sizeOfInput);
printf ( "Bubble sort sizeOfInput after inner loop is %d :\n",sizeOfInput);
}
printf ( "Bubble sort total array size at the end is %d :\n",sizeOfInput);
for ( c = 0 ; c < sizeOfInput; c++)
printf("Element: %d\n", a[c]);
}
I am using Micosoft Visual Studio Command Line Tool for compiling this on a Windows XP machine.
cl /EHsc bubblesort01.c
My friend gets the correct output on a dinosaur machine (code is compiled using TCC there).
My output is unexpected. The array mysteriously grows in size, in between.
If you change the code so that the variable sizeOfInput is changed to sizeOfInputt, it gives the expected results!
A search done at Microsoft Visual C++ Developer Center doesn't give any results for "sizeOfInput".
I am not a C/C++ expert, and am curious to find out why this happens - any C/C++ experts who can "shed some light" on this?
Unrelated note: I seriously thought of rewriting the whole code to use quicksort or merge sort before posting it here. But, after all, it is not Stooge sort...
Edit: I know the code is not correct (it reads beyond the last element), but I am curious why the variable name makes a difference.
i want to return wchar_t frm a function. How can i implement it
wchar_t wcstring1[newsize1]
How to return "wcstring1" from a function and make it to save into another variable of same type(In another function)
I'm trying to implement a Chord distributed hash table. I want to use SHA-1 as the hash function to generate node ids and map values to the DHT. However, I'll need to use numerical operations on the SHA-1 generated key, such as a modulo, for example. I wonder in which type of variable should I put the array of bytes I get, and how can I convert from one to another.
Hi,
I want to send the following JSON text {"Email":"[email protected]","Password":"123456"} to a web service and read the response. I know to how to read JSON. The problem is that the above jason object must be sent in a variable name jason. How can i do this from android? Like creating a request object setting content headers etc.
Hi,
I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that:
file = open(filename, 'rb')
while 1:
byte = file.read(8)
# Do something...
So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks.
In Python I have a list of n lists, each with a variable number of elements. How can I create a single list containing all the possible permutations:
For example
[ [ a, b, c], [d], [e, f] ]
I want
[ [a, d, e] , [a, d, f], [b, d, e], [b, d, f], [c, d, e], [c, d, f] ]
Note I don't know n in advance. I thought itertools.product would be the right approach but it requires me to know the number of arguments in advance
I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code:
std::map<std::string name, std::vector<int> scores> myMap;
In this example it clearly says and no other comment is needed, what for we are using myMap variable.
Looking forward to your opinions.
hello i want to get ipaddress of my computer in variable ip thru this code
but it assign nothing in ip
char comm[100];
int s=0;
char ip[100];
sprintf(comm,"export ip=`/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'`");
s=system(comm);
printf("\n ip is %s",ip);
Before Entering data into a database, I just want to check that the database doesn't have the same username in the database already.
I have the username in SQL set as a key, so it can't be duplicated on that end, but I am looking at finding a more user-friendly error message then "KEY already exists".
Is there are simple way to check if the variable value already exists in a row?
Thanks!
Hi, i need to check the type of a variable in javascript, i know 3 ways to do it:
instanceof operator: if(a instanceof Function)
typeof operator: if(typeof a=="function"
toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]"
Which is the most accurate way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.
I have a PHP based web application which is currently only using one webserver but will shortly be scaling up to another. In most regards this is pretty straightforward, but the application also stores a lot of files on the filesystem. It seems that there are many approaches to sharing the files between the two servers, from the very simple to the reasonably complex.
These are the options that I'm aware of
Simple network storage
NFS
SMB/CIFS
Clustered filesystems
Lustre
GFS/GFS2
GlusterFS
Hadoop DFS
MogileFS
What I want is for a file uploaded via one webserver be immediately available if accessed through the other. The data is extremely important and absolutely cannot be lost, so whatever is implemented needs to a) never lose data and b) have very high availability (as good as, or better, than a local filesystem).
It seems like the clustered filesystems will also provide faster data access than local storage (for large files) but that isn't of vita importance at the moment.
What would you recommend? Do you have any suggestions to add or anything specifically to look out for with the above options? Any suggestions on how to manage backup of data on the clustered filesystems?
I'm trying to program a Hebrew site with a search option.
I am using php 5 with Apache 2.2, on a Debian 5 (Lenny) with
appropriate code pages enabled.
I am using _POST to pass arguments to a script. If I pass
English word to the script everything works, but when I use Hebrew
nothing is passed through the POST function. When I use ECHO
to show _POST, the variable is empty.
What might be the problem?
Hi
I have an app that creates a variable number of ScatterviewItems based on which tagged object is placed on the surface table.
The ScatterViewItems are added programatically to the ScatterView based on info looked up in a DB
The Scatterview does a good job of displaying this info
However, I would like them to be
evenly distributed across the table and
not have any items overlapping
Any ideas how to do that?
Under Firefox, I want to do something like this :
I have a .htm file, that has a button on it. This button, when I click it, the action will write a text inside a local .txt file. By the way, my .htm file is run locally too.
I have tried multiple times using this code, but still cant make my .htm file write to my textfile:
function save() {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
} catch (e) {
alert("Permission to save file was denied.");
}
var file = Components.classes["@mozilla.org/file/local;1"]
.createInstance(Components.interfaces.nsILocalFile);
file.initWithPath( savefile );
if ( file.exists() == false ) {
alert( "Creating file... " );
file.create( Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 );
}
var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"]
.createInstance( Components.interfaces.nsIFileOutputStream );
outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 );
var output = 'test test test test';
var result = outputStream.write( output, output.length );
outputStream.close();
}
This part is for the button:
<input type="button" value="write to file2" onClick="save();">
I have a formula which is working; the formula uses an array. I tried to extract the formula to create a custom formula but now get an error in the syntax.
I am wondering if the array is causing the problem as the error is on the line:
last_element_current:=val(sc_array[1]) + 1;
and the error is: the ) is missing and highlights the variable sc_array before the index [1].
HOWEVER! would setting the $link to my database be one thing that I prolly should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is on the global scope would be wise.
I am currently using the functions to transfer it back and forth so that way I do not have it on global...but it is a bit of a hinder to my script.
Please Advise,
Thank you.

This probably an easy thing to do but for some reason I can't get a handle on it.
I have a simple form that allows people to select one if three items for sale. When they chose their item I need to pass that variable into an iFrame with a third party checkout page to safely process their cc transaction.
How would I do this?
Cheers-
