Hi, I'm working with huge double arrays (300x300 or 640x640) and I need to write them to a txt file, but it takes too long...
Anyone knows a way to write the arrays faster?  It doesn't matter if I have to write them in another format.
Thanks

if speed is important, choose a binary file, not a text file.
foreach (double d in myArray) binaryWriter.Write(d);
|
|
|
|
|
If you don't much care about the format of the file, use Serialization (with a binary formatter).
Look it up in MSDN, or articles here.

Hi, thanks for the help.
The thing is that i want to write these arrays for easy visualization. Writing them to a txt file seem easy to me to read and compare between them by eye.

|

of cource, you need to serialize it in a class

This works without any problems:
TcpChannel myChannel = new TcpChannel();
ChannelServices.RegisterChannel(myChannel, false);
ICustomer objCustomer = (ICustomer)Activator.GetObject(typeof(ICustomer), "tcp://localhost:8000/Customer.rem");
BindingList<ICustomer> customers = objCustomer.GetCustomers(); My form has a binding source which I set the DataSource property to the customers object. The form also has a Binding Navigator which pulls form the BindingSource.
If I set the AllowNew property on the customers list to true I get the "+" icon on the BindingNavigator. Exactly what I want.
However, when I click that icon it attempts to make a new object of the interface type ICustomer. Obviously not possible.
So, I handle the AddingNew event of the list with this:
void customers_AddingNew(object sender, AddingNewEventArgs e)
{
ICustomer newCustomer = (ICustomer)Activator.GetObject(typeof(ICustomer), "tcp://localhost:8000/Customer.rem");
e.NewObject = newCustomer;
}
Sadly, that gives me the error:
"Because of security restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed."
I've read up on this err and found that if you change the typeFilterLevel of your remoting formatter it would work. I'd prefer not to do that.
Info on that was found here:
http://www.thinktecture.com/resourcearchive/net-remoting-faq/changes2003
If they changed this behavior in .Net 2.0 than it was probably for a good reason. There has to be another way to do this? Is it not best practice to code towards interface types? What's the solution for dynamic lists over remoting when using interface types?
-Mike.

I need to develop a program that will automatically find all the entries of another program in registry and automatically delete those entries.
Currently, when some installation problem occurs, i can neither install nor uninstall one of my developed software. So I need to manually remove all the entries from registry. I need to make it automatic by running a C# application. Can anyone help me in this regard?
One more thing, i don't even know accurately which files to delete. I usually search registry by the software name and remove them from registry. Now how can i implement the whole thing ?
Please help me in this issue. thanks...

When I create a new VB control library, it creates a skeleton, which Builds fine.
When I create a new C# control library, it creates a skeleton, which gives the following build message:
Warning 1 Invalid search path 'C:\Program Files\Microsoft Visual Studio .NET 2003\SDK\v1.1\Lib\' specified in 'LIB environment variable' -- 'The system cannot find the path specified. '
I've searched the project, and nowhere is this path referenced. The project properties LIB path is blank.
I am using VS.Net 2005.
Any help?

Taking a wild stab in the dark, i'd say that your LIB environment variable specifies that path, and that that path does not exist.
Environment variables are configured through control panel, system, advanced, environment variables.

Thank you! That was it.
Wierd that it only gave that message for C#, not VB.

Is there something in C# that i can call to get the current system time to the millisecond?
|
|
|
|
|
DateTime.Now() returns current time

Yes there have been several cases so I decided to solve it somehow. It would be cool if it had the same capabilities as in VS `

I don't want to look picky, but DateTime.Now is a property, not a method. In my newbie times, this would have confused me.

Background: I am building a custom XML editor slash encryption tool.
I am having a problem dealing with multiple people accessing the same file (or a single person accessing the same file). What I am looking to do is if the file is currently open the user is prompted that the file is already open and only has read access.
Right now the user can open a file that is already open, then when either people with the same file go to save an error is thrown and the file is locked against any saving.
So my question is:
1)Is there a way to check if a file is already open?
2)If the file is open, the original person who opened keeps writing privilege well the other user is only given read access?
3)Can I prevent the file from being locked?
Thanks for the help.

When creating a new instance of FileStream class you can specify how other programs can access the file by FileShare enumeration
|
|
|
|

I will give that a try, thank you

I am getting an access error using this code:
try
{
m_oZipFile = new ZipFile(new FileStream(l_szLocation, FileMode.Open, FileAccess.ReadWrite, FileShare.Read));
}
catch
{
m_oZipFile = new ZipFile(new FileStream(l_szLocation, FileMode.Open, FileAccess.Read, FileShare.Read));
}

What error are you getting?
