I'd like to write a program which reads user input only from tty, instead of redirected stdin pipes, like passwd and ssh do. Is there any approach?
Many thanks
I'm making a simple chat program for me and my friends as a tech demo. I had the idea to have a small drawing pad thing that would be shared between all connected users.
What could I use in this situation (control wise)?
I know I can convert an image to a byte[] and pass that to everyone, but I'd need to use a pictureBox to get said image.
Thanks for the help!

In their dev site,AOL says the contacts api would coming soon from the year 2008-_-
but I can't find anything about it since then, and I find in window live add contacts site:
http://cid-7b76c1c8e1ade1ea.profile.live.com/connect/
They have a program to port contacts from AOL, that is this only for Microsoft. Is there another method to do this?
How do you take a commmand like this in PowerShell and split it across multiple lines:
&"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -verb:sync -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" -dest:contentPath="c:\websites\xxx\wwwroot\,computerName=192.168.1.1,username=administrator,password=xxx"
I'm looking to export a page that looks good in print media, to word.
Can this be done automatically, or mostly automatically with office apis?
The alternative is to create a program that reads all our style meta data and font meta data and convert to word and force a download.
The issue is our style metadata is already built for css, its a web app after all. And writing my own css parser, doesn't sound like a good use of time.
I have a program and as it's done now, it has a data directory with something like 10-30K files in it and it's starting to cause problems. Should I expect that to cause problems and my only solution to tweak my file structure or does that indicate other problems?
Is there a free or open source library to read Excel files (.xls) directly from a C# program?
It does not need to be too fancy, just to select a worksheet and read the data as strings. So far, I've been using Export to Unicode text function of Excel, and parsing the resulting (tab-delimited) file, but I'd like to eliminate the manual step.
Hi,
I want to backup my web site regularly but instead of backup my files via ftp program I want a one-click solution which will copy all my files and zip them and allow to download. Can this be done with asp.net at same web site or I have to write a .net app for this purpose?
In general, what would make your program more maintainable?
I know a lot of folks that make heavy use of Singletons, but that seems like a cop-out, which creates a kind of global junk drawer organization.
Consider an object declared in a method:
public void foo() {
final Object obj = new Object();
// A long run job that consumes tons of memory and
// triggers garbage collection
}
Will obj be subject to garbage collection before foo() returns?
UPDATE:
Previously I thought obj is not subject to garbage collection until foo() returns.
However, today I find myself wrong.
I have spend several hours in fixing a bug and finally found the problem is caused by obj garbage collected!
Can anyone explain why this happens? And if I want obj to be pinned how to achieve it?
Here is the code that has problem.
public class Program
{
public static void main(String[] args) throws Exception {
String connectionString = "jdbc:mysql://<whatever>";
// I find wrap is gc-ed somewhere
SqlConnection wrap = new SqlConnection(connectionString);
Connection con = wrap.currentConnection();
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_READ_ONLY);
stmt.setFetchSize(Integer.MIN_VALUE);
ResultSet rs = stmt.executeQuery("select instance_id, doc_id from
crawler_archive.documents");
while (rs.next()) {
int instanceID = rs.getInt(1);
int docID = rs.getInt(2);
if (docID % 1000 == 0) {
System.out.println(docID);
}
}
rs.close();
//wrap.close();
}
}
After running the Java program, it will print the following message before it crashes:
161000
161000

Finalizer CALLED!!
********************************
********************************

********************************

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
And here is the code of class SqlConnection:

private Connection connection;
public SqlConnection(String connectionString) {
this.connectionString = connectionString;
}
public synchronized Connection currentConnection() throws SQLException {
if (this.connection == null || this.connection.isClosed()) {
this.closeConnection();
this.connection = DriverManager.getConnection(connectionString);
}
return this.connection;
}
protected void finalize() throws Throwable {
try {
System.out.println("********************************");
System.out.println("Finalizer CALLED!!");
System.out.println("********************************");
this.close();
} finally {

}

System.out.println("********************************");
System.out.println("Close CALLED!!");
System.out.println("********************************");
this.closeConnection();

} catch (Throwable e) {
} finally {
this.connection = null;

Is there any plug-in that provides an integrated shell (i.e. command prompt) in Eclipse?
The console only seems to be for interaction with a running program.
I've found a reference to the plug-in Open extern but that opens an external command window, and I'd rather have it integrated with Eclipse.
have to check some formulae whether they are providing correct result, these formula are written part of a VB program, what is the best tool\method to unit test these formula?
I've done a lot of research on when it's correct to release things, but it's all confusing to me. I think sometimes the Leaks program is off. Anyway...
background is a UIImageView
background.image = [UIImage imageNamed:@"greenbackground.png"];
Do I have to release background? I never alloced it and it's not set as a property, so I'm thinking no.
This is a very newbie question.
I want to know how to create a WEB APP to make Call ( using VOIP protocoll I think ).
What program languages do I have to learn ( client and server side ) ?
public class WrapperTest {
static {
print(10);
}
static void print(int x) {
System.out.println(x);
System.exit(0);
}
}
In the above code System.exit(0) is used to stop the program. What argument does that method take? Why do we gave it as 0. Can anyone explain the concept?Thanks.

I want to use the performance counter output in my program. How can I access the performance counter in code without using the perfmon.exe. I want to create my own performance counter app.
I just installed QT 4.6 on snow leopard 10.6.3. I wrote a really simple program. I can generate a xcode project using qmake, but I can't step into QT function. How can I set it up?
I can't figure out where exactly to go in order to write the Ruby code itself. I know that I can enter things line-by-line in Terminal (I'm on a Mac), but I'd like to figure out how to start using something like Xdrive (Apple won't allow me to download Xrive because I have OS X 10.5, not 10.6).
What steps do I need to take in order to start writing code in a program like xDrive.
Thank you in advance.
Is there a definitive guide for special folders in windows? An internet search yielded just a few crumbs of information, e.g.
Wikipedia:Special Folders
Windows 7 Client Software Logo Program
What I'm looking for is an explanation of each folder, its intended purpose, usage scenarios and motivation for its existence (e.g. what does Local App settings provide for that App settings doesn't). A matrix/table of requirements/uses against folder would be handy I think.
Is there a recognized, recommended, or standard form for representing the structure of JSON? E.g., my service returns a structure, effectively, represented as JSON. How do I describe what my service returns, such that another service can consume that JSON and program to its interface?
