For clarification: I know how evil globals are and when not to use them :)
Is there any performance penalty when accessing/setting a global variable vs. a local one in a compiled C++ program?
write a program to find the sum of the logarithms of all the primes from 2 to some number n, and print out the sum of the logs of the primes, the number n, and the ratio of these two quantities in python
I am aware of some the obvious gains of the x64 architecture (higher addressable RAM addresses, ect)... but:
What if my program has no real need to run in native 64 bit mode. Should I port it anyway?
Are there any foreseeable deadlines for ending 32 bit support?
Would my application run faster / better / more secure as native x64 code?
Suppose I have variables for positions like
const float latitude = 51.+11./60.+33.0461/3600.;
const float longitude = 12.+50./60.+31.9369/3600.;
and use them frequently in the program. Does the compiler precompute that?
(This example should not produce much overhead, but you get the point.)
Bonus point for pointing out location. ;)
TIA
I have a sinatra service foo.rb
To run it I on a different port I would type "ruby foo.rb -p 5000".
While the program is running I would like to be able to get the port (in this case 5000) and other information. Is there a way to get info like this while the app is running?
Thanks
I'm writing a program that should display the amount of unread sms, mms, phone calls and emails. It was quite easy to find how to query for sms and phone calls (I used the search on this page) but I have not been able to find out how to query for emails.
Is there anyway to find out how many unread emails the user got in their phone?
I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?
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

Below is my $.ajax call, how do I put a selects (multiple) selected values in the data section?
$.ajax({
type: "post",
url: "http://myServer" ,
dataType: "text",
data: {
'service' : 'myService',
'program' : 'myProgram',
'start' : start,
'end' : end ,
},
success: function(request) {
result.innerHTML = request ;
} // End success
}); // End ajax method
EDIT I should have included that I understand how to loop through the selects selected options with this code:
$('#userid option').each(function(i) {
if (this.selected == true) {
but how do I fit that into my data: section?
I know php scripts don't actually compile until they are run. However say I want to create a small simple program and compile it to a binary without requiring the php binary. How could I do this?
I'v seen a few IDE's out there that would do this, but either they are all for windows or the linux versions don't actually build properly.
What I would like is something like py2exe that does it in the script itself.

I need to write a program or script that does a few things with (or to) a server after a Windows install. Among those is adding the server to a domain.

I wrote a wrapper DLL for some native c++ functions and compiled it in c++/CLI, then I added a reference to C# project, functions indicates there, but when I try compile project I get this error:
"Additional information: Could not load file or assembly 'lib, Version=1.0.3742.39593, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format. "
What's the problem ?
Thanks.
I have an erlang program which runs a server on a local machine and I would like it to start a local web browser and point to itself on startup. How can I do this in a portable way across Windows XP. Vista, and Windows 7?
I have been using this "logic" in C++ and VB with success, but am tied up in Java...
Simply put,
public void DataProviderExample(String user, String pwd, String no_of_links,
String link1, String link2, String link3) {
for (int i=1;i<=no_of_links;i++) {
String link = "link"+i;
System.out.println(link);
}
Now, if the variables link1, link2 and link3 have a value of "X", "Y" and "Z" respectively, upon running this program, I get the following output -
link1
link2
link3
What I want is -
X
Y
Z
Any ideas?
I would like to create a C# program that creates an MSI based on a number of parameters. For example, based on user settings, certain files would be included, or runtime parameters set.
Can anyone point me towards any documentation that might help, or give me an idea where I might start with something like this?

Hi,
I'm trying to handle errors that have occurred on other threads the .NET CF program is like below:
static void Main()
{
Thread t = new Thread(Start);
t.Start();
...
}
void Start()
{
... Exception here
}
In my situation, putting try catch in the Start method is impossible. How can I handle it in the global code?
When I try to compile my program the compiler complains about this line in a .h file that I #included.
ostream & Print (ostream & stream);
How can this be fixed?
