I'd like to prove that a GUID is not unique in a simple test program.
I expected this to run for hours but it's not working. How can I make it work?
BigInteger begin = new BigInteger((long)0);
BigInteger end = new BigInteger("340282366920938463463374607431768211456",10); //2^128
for(begin; begin<end; begin++)
Console.WriteLine(System.Guid.NewGuid().ToString());
I'm using C#

What is the best way to update a Java or GWT program from MySQL. For example, a MySQL database which holds Weather information... updating whenever the weather changes a degree. How would I update a Java / GWT field with each update. Would I use a thread to query every few seconds??

Hi I have a wordpress installed on
h*ttp://domainname.com
and I would like to have replication of the same website on a subdomain for example
h*ttp://sub1.domainname.com
h*ttp://sub2.domainname.com
What should I do to make this happen without copying any database and the wordpress should be smart enough to recognize the "sub1" and "sub2" to be used later in the program.

hey ,
I'd like to make a recursive function using C++
I make this class

{
private:
struct node
{
int data;
node *link;
}*p;
void linklist::print_num(node* p)
{ if (p != NULL) { cout << p->data << " ";
print_num (p->link); }
}
in the main program what should I write ...
As per subject.
I have some constants hash defined like so:
#define CONST 40
I've set a break point in my program. How do I print the value of that constant? (I know I can just look at the source code, but I want to be sure of it)
My iPhone app started logging this error:
lo-hi recycling invariant violated!
followed by:
Program received signal: “EXC_BAD_ACCESS”
whenever I launched it on my iPod (3.1.3) and sometimes when I launch it in the simulator.
What does this error mean, and how can I fix it?
I am using cover-flow in my app. I think this might be the problem.
Thanks in advance.
I'm trying to convert an old Delphi program I wrote into Java to compile and run on my Android phone. I'm running the Android 2.1 operating system but am using version 1.6 of the SDK.
I have a routine in Delphi where I set the colour of pixels on a canvas individually along the lines of:
image1.canvas.pixels[x, y] := GetMyTColor(x, y);
Is there a Java equivalent to the property on the Canvas:
property Pixels[X, Y: Integer]: TColor
What is a better way to program the following SQL:
str_to_date(
concat(convert(D.DAY, CHAR(2)),
'-',
convert(M.MONTH, CHAR(2)),
'-',
convert(M.YEAR, CHAR(4))),
'%e-%m-%Y' ) as AMOUNT_DATE
I want to convert the columns D.DAY, M.MONTH, and M.YEAR to a date field using MySQL. The above works, but seems much more complicated than it needs to be. (If there's an ANSI SQL way to do it, that would be even better.)
Thank you!
I am trying to create a map app for iphone and I have a little problem. Every pin on the map has a different name. How can my program know which pin button is pushed so it can get the data from the server. I've created only one detailed view and I don't know how to make this work.

Hey, id like to make this as fast as possible because it gets called A LOT in a program i'm writing, so is there any faster way to initialize a C++ vector to random values than:
double range;//set to the range of a particular function i want to evaluate.
std::vector<double> x(30, 0.0);
for (int i=0;i<x.size();i++) {
x.at(i) = (rand()/(double)RAND_MAX)*range;
}
EDIT:Fixed x's initializer.
I am using JNI to initialize classes in my jar files present at the classpath. But created executable uses java and displays ugly command prompt when my program starts. I want to configure my JNI to use javaw instead. How can I achieve it?

Hi all, We need to find a way to programatically *link all the tables* in a SQL Server database to an access db. We will be invoking this access database from a program that uses .net/SQL Server 2008.
While invoking the application we would like to add the linked tables so that the users can just run the reports/modules from access without having to worry about linking the tables. Is there a way we can do this?
Thanks!
I've noticed that changing the background color of an android widget (f.ex. Button or TextView) by program:
myButton.setBackgroundColor(Color.BLUE);
makes it to loose its 3D shape, border, and shadows effects, and then appears like a ugly flat square. What am I missing?
Sorry for the very naive question but I couldn't get it right although tried for a time.
I have a strange problem in C++. An address of a Boolean gets "destroyed" but it doesn't get touched. I know that there are beater way's to accomplish what I try to do, but I want to know what I do wrong.
I have a main class; this main class contains a vector of another class. There is a strange problem when a new instance gets created of this object.
This is how my code works:
There will start a thread when the constructor gets called of the “2nd”object. This thread gets as Parameter a struct. This is the struct:
struct KeyPressData
{
vector<bool> *AutoPressStatus;
vector<int> *AutoPressTime;
bool * Destroy;
bool * Ready;
};
The struct gets filled in the constructor:
MultiBoxClient::MultiBoxClient()
{
//init data
DestroyThread = new bool;
ReadyThread = new bool;
AutoThreadData = new KeyPressData;
//Reseting data
*DestroyThread = false;
*ReadyThread = false;
//KeyPressData configurating
AutoThreadData->AutoPressStatus = &AutoPressStatus;
AutoThreadData->AutoPressTime = &AutoPressTime;
AutoThreadData->Destroy = DestroyThread;
AutoThreadData->Ready = ReadyThread;
//Start the keypress thread
CreateThread(NULL,NULL,(LPTHREAD_START_ROUTINE)AutoKeyThread,AutoThreadData,NULL,NULL);
}
As long as the constructor is running will the program run fine. But when the constructor closes the address of the “AutoThreadData-Destroy” will get corrupted. The program will crash when I call the value of the pointer.
void WINAPI AutoKeyThread(void * ThreadData)
{
KeyPressData * AutoThreadData = (KeyPressData*)ThreadData;
while(true)
{
if(*AutoThreadData->Destroy == true) //CRASH
{
*AutoThreadData->Ready = true;
return;
}
Sleep(100);
}
}
What did I test:
I logged the address of the AutoThreadData and the AutoThreadData-Destroy when the constrcutor is running and clossed; the AutoThreadData address is equal to AutoThreadData when the constructor is closed. So there is no problem here.
The address of AutoThreadData-Destroy gets destroyed when the constructor is closed. But how can this happen? The Boolean is on the heap and the KeyPressData struct (AutoThreadData) is on the heap.
Destroy before: 00A85328
Destroy after: FEEEFEEE
Can someone maby explain why this crash?
I know that I can send a pointer to my class to the thread. But I want to know what goes wrong here. That way I can learn from my mistakes.
Could someone help me with this problem?
Thanks!
I am the technology director at a small nonprofit, and we are in the process of making a new website. We have several proposed mock-ups of different homepage designs, and need to receive input from our board members. Is there an online application/program/framework that will receive and organize user comments? I'm looking for something that will allow commenting while viewing the page, rather than just a message board or wiki.
Modern keyboards have special multimedia keys, e.g. 'Pause/Play' or 'Open Web Browser'. Is it possible to write a program that "presses" these keys?
I would prefer solution in C, but I would accept a language agnostic solution, too.
It's fairly simple to play a sound file, say temp.wav, from Visual Studio C#. I'm looking for a way to do this without temp.wav being locatable from the machine running the program.
IE - I want to read the .WAV file into my solution so that it is somehow inside of my .EXE and be played by it.
Is this possible?
