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);
Hello everyone,
I have variable length character and want to store in SQL Server (2005) database. I want to learn some best practices about how to choose TEXT SQL type or choose VARCHAR SQL type, pros and cons in performance/footprint/function.

I have a program that I'm working on that register global hotkeys
I would like to use that ability to trigger highlighted text or data to be copied to the clipboard and then read from the clipboard into a variable in my program
which i will later use in reverse to paste it back out.
(example ctrl+1 copys to quque #1 and alt+1 pasts what is in quque 1)
thanks so much.
In scripting languages like Perl, it is possible to read a file into a variable in one shot.
open(FILEHANDLE,$file);
$content=<FILEHANDLE>;
What would be the most efficient way to do this in C++?
How can i acces an Array Element in Smarty with a second variable as index?
Imagine i have an array of language
[99] = Array
(
[language] = English
)
I tryed this :
$memberLanguage.id is 99
so logicaly you would acces it this way
{$language.$memberLanguage.id.language} but this doesnt work.
in PHP i would do it this way
$language[$memberLanguage['id']]['language']
How can i access the Array Element Dynamicaly?
defined variable:
LinkedList list1=new LinkedList();
Object get() in list1 obtains a node of list1
Object remove() in list1 deletes a node of list1

for(int i=1;i<list1.count();i++){
if(list1.get(i).startsWith('"',0)) //Error here
list1.remove(i);
}
Error: cannot find symbol
symbol: method charAt(int)
location: class Object
how to fix this problem?
I would like to delete the node in list1 which starts with (").
how can I get user_version into an expression (for SELECT or WHERE) ?
I would also appreciate any clue to how to save ANY global variable in SQLite.
Does anyone know of such an extension (dll) ?
BTW: I know that PRAGMA user_version; gives me the right answer, but I cannot use that inside a WHERE-clause !
Hi,
what the syntax is in Action Mailer Basics rails guide ?
class UserMailer < ActionMailer::Base
def welcome_email(user)
recipients user.email
from "My Awesome Site Notifications <[email protected]>"
subject "Welcome to My Awesome Site"
sent_on Time.now
body {:user => user, :url => "http://example.com/login"}
end
end
How should i understand the construction, like
from "Some text for this field"
Is it an assignment the value to a variable, called "from" ?
I have
<form name="feedback" method="post" onsubmit="return checkform()" action="engine.php?ad=">

engine.php?ad=, which is
<?=$_GET['page'];?> in php (pass a URL param to the next page using this.)
How would I go about adding that?
I also have it in javascript if needed.

The scenario is as follows:
Create an instance of a class (std::map) and
sore it as global variable.
Spawn threads.
Threads read and use the same global
instance of the class
All spawned threads quit
Global class instance is destroyed
No mutex, no thread modifies the global class instance.
Is this OK?
Thank You
Let's say we have one or more environments and variables in them.
My question is how we access the values of these variables, parametrically.
rm(list = ls())
env1 <- new.env()
env1$var1 <- "value1"
env2 <- new.env()
env2$var2 <- "value2"
env <- ls.str(mode="environment") # We get the environments
var <- ls.str(eval(parse(text = env[1])))# We get the variables of an environment
eval(var[1]) # We fail to get the value of a variable
Thank you all, in advance
Hi
I am creating a stored procedure to which i want to pass as variable a comma delimited list of Ids
I want to use the Ids into a select statement

WHERE a.Id IN(@Ids)
Obviously i get the error that @Ids is a varchar and not an INT but how can i convert the comma delimited list

Hi,
What does address operator mean.
say in the method below.
what should be passed in the method as parameter value of integer or the address of an integer variable.
void func1(int&)// method declaration
void func1(int& inNumber)//method definition
{
//some code
}
I'm currently using the following code for thread-safe access of a variable.
int gnVariable;
void getVariableValue(int *pnValue)
{
acquireLock(); //Acquires the protection mechanism
*pnValue = gnVariable;
releaseLock(); //Releasing the protection mechanism
}
I would like to change my API signature to a more user-friendly
int getVariableValue(void);
How should I rewrite the function - such that the users of the API don't have to bother about the locking/unlocking details?
I want to have a url like this:
domain.com/css/site.css?test=234
Rule:
RewriteEngine On
RewriteRule ^([a-z]+)/$ $1.php
RewriteRule ^css/([a-zA-Z0-9]+).css?count=(.*)$ css.php?f=$1&test=$2
But I get every time a 404: Not found (site.css)
If I have a rule like that it works, just without getting the $_GET-Variable:
RewriteEngine On
RewriteRule ^([a-z]+)/$ $1.php
RewriteRule ^css/([a-zA-Z0-9]+).css$ css.php?f=$1
Every time i pass some parameters to a JavasScript or jQuery functon, i use some random letters. What are the correct letters for the corresponding variable types?
function(o){} for example is for a object. But what are the other letters? Do someone have a list of those?
In C# you can declare an enum and once you have set its value call ToString on the variable and get a string representation of the value of the enum.
How do you do this in C++/CLI using a managed enum?
How can I get the relative path of the folders in my project (using code)?
I created new folder in my project and I want its relative path so no matter where is the app the path will be correct.
Maybe this can be useful:
I trying to do it not inside any function just inside the class and I want to init with it a final variable. the app is android and the class is "extends Activity"
thanks
cut -d" " -f2 ${2} | $callsTo
hello, can somebody please explain can I pipe the result of cut to variable callsTo, and how will it be stored, as the string or list?
In c it would be:
while(1){
i++;
printf("%d \r",i);
}
I assume the textview and the variable and the timer get created in oncreate, then there is a timer handler with an increment and a settext and a sleep? Seeing how to do this in androidese would really clarify things I think. Thanks.
What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable?
For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?
I just came back to C++ Builder after 5 or more years away. I seem to remember a nice tool where I could drag its pointer over the GUI of my running application and get lots of info about what was pointed at - handle, size, text, parent, children, etc
IIRC, if the exe include debug info I could also get the actual variable name as used in the source.
Does anyone know what program I am talking about? Thanks
