Re: one question related to the memory and sources release

I meant post just the bit of code that does the looping.

1) What on earth is this meant to mean?
Dictionary<string,>>>
You need to escape any < or > signs in your code with < or > before you can post them.

2) Code should be posted within <pre> </pre> tags to make it more readable.

//Like this
if(testValue)
{
    // See how it's nicely formatted and readable.
    Console.WriteLine("test");
}

Hi, Simon,

by the way, I saw one simulaiton tool, they provide one button to "clear the simulation", then it gives the message "Clearing memory of the simulation". that means the memory used by the simulation has been cleared. I don't know how to clear the memory used by the simulaiton? If I know how to do it, it may help me to improve my own simulation tool, especially when we have many loops.

Do you have the experiences on it?

thank you for your kind help!!

In .net you don't need to clear memory. Most .net objects are "managed" which means their memory is automatically reclaimed by the garbage collector, provided you don't hold references too them after they should have gone out of scope, so you don't need to worry about it.

When a class uses unmanaged memory, it will implement the IDisposable interface. In this case, you just call the Dispose() method when you are finished with it to release the objects unmanaged memory.

I've only briefly looked over your code, but I can't see any types in there that need disposing of.

One thing I like in Java is that their UI elements can all be interconnected around an Action object. You create an AbstractAction with an Icon and a description string, and then you can associate it with any controls, which will all have the same action when activated (click a button, select a menu item, click a toolbar button, etc...), have the same description, and are all enabled and disabled together, all that through the Action object. I haven't tested to see if changing the icon and the description also cascades.

Is there a similar functionality in C# 2.0? Did someone write some class with this functionality? I realize that it's not very hard to code by oneself, but if I can use a proven implementation, or work with someone else, all the better.

EDIT : precised that I want .NET 2.0
This has been added to the framework in C# 3.0, but I must use .NET 2.0

Is there anything in .NET 2.0, though? (I forgot to mention that, sorry)

How To discover websevices Method

14-Oct-08 6:07

Can't think of anything. (That doesn't mean that there isn't. the framework is too big for me to remember everything). Last time I wrote an in .net 2.0 thought I wrote my own command handling framework, which I used on several projects.

a way to execute the file on list view by doubleclick

Re: a way to execute the file on list view by doubleclick

14-Oct-08 4:37

Hello everyone!!!

Me and this problem again!!! =D

This is my code:

private void lvFiles_SelectedIndexChanged(object sender, System.EventArgs e)
{			
        ShellLib.ShellExecute shellExecute = new ShellLib.ShellExecute();
	shellExecute.Verb = ShellLib.ShellExecute.OpenFile;
	shellExecute.Path = @"F:\Painel de Controle ETECH\Projetos ETECH\{0}\80010005.dwg";
	shellExecute.Execute();
			
}

It works BUT open only the file written in the shellExecute.Path statement
I need to find a way to execute a selected file on the list view...
Well I´d many ideas and none worked.. I was thinking to put the selected file on a string and then to put this string on the end of the path statement but I didn´t figure out how to do it and mainly how to put the file name on a string when I select it on the list view control!

Could anyone help me?? I´m very desperate!!!!

best wishes for all!!!

if you mean shellExecute.Path = someString; yes that would be the thing to do.

shellExecute.Path = someString; and someString represents the path to the file I selected on the listView control. Yes, It means that I´m in the right way now. The problem is right here... select the file in the ListView and put it´s path and it´s name on a string...

I´m a totally dummy with event oriented programming. My knowledge is structured C, Data Structures on C.. I can do an entire B-Tree using C but I can´t implement a simple event.. oh shame on me... =(

How are you populating your listview with the files? Where is the file information coming from?

Each ListViewItem has a Tag property that holds an object. Save your full path to the file in there. When you need it, just cast that ListViewItem's Tag to a string and you've got the file's path.

Alternatively, create a custom ListViewItem that has a Path property, then you can cast the entire item to your class and access the Path property.

public class ListViewItemWithPath : ListViewItem
    {
        public ListViewItemWithPath(string fileName, string path)
        {
            Text = fileName;
            m_Path = path;
        }
        private string m_Path;
        public string Path
        {
            get { return m_Path; }
            set { m_Path = value; }
        }
    }

	ShellLib.ShellExecute shellExecute = new ShellLib.ShellExecute();
	shellExecute.Verb = ShellLib.ShellExecute.OpenFile;

It is pretty easy.
Right click your Deployment project -> Select View -> File System:
File System View will be displayed.

You can either right-click to select a Special folder or use for example Application folder.
Enter Application folder for this example and right click again. You will see the required menus to add a file, Project output, etc...

Hope this helps...

Always keep the Murphy Rules in mind!

Crystal Reports has the required merge modules on their website. Integrate them into your deployment project and it will go fine. Another option is to download the MSI for the particular version from their site and manually run them on the deployment server.

As a parent, sometimes you have to watch your kids. You have 2 ways to do this; either limit their actions entirely or snoop in on them. I have the need to do the latter. As somewhat of a beginner / intermediate developer, I want to create some sort of application to monitor, log and report my children's activities on their respective PCs.

After reading the board for a good week now (both VB.NET and C#) I know that this type of post isn't welcomed at all, and I will probably get scolded for branching on the topic due to it's controversy with flirting on the distinct line of privacy invasion but here it goes;

I want to create a "key logger" of sorts, to monitor what people do, who they chat with and what they are chatting about. After reading a bunch, trapping the print screen seems like a nice start, but I am afraid that if done frequently, will I be eating to much resources, slowing down the machine, eating to much network traffic and allocating to much disk space where my child will know what is going on? I am not concerned about AV because my child, albeit knowledgeable of computers to a degree, doesn't have an AV.

So I guess, where would I start looking to trap all keys pressed in whichever application, or at least solely MSN chat windows and internet explorer. I am not after login and passwords here, just trying to make sure my family stays 'kosher'.

So before you distrust the post, understand I wouldn't resort to this unless I had to.

Thanks in advance for the reading.

If I had children of the sort of age that I would worry what they were up to on their PCs, there is no way I would allow them to surf the internet unsupervised.

The internet is a crazy place with all sections of humanity in attendance, why would you let your child roam free there?

What are you talking about then. Someone >= 20?! If so, you need to let go. Someone over 20 is old enough to make their own decisions. If they want to browse dubious portions of the internet that is up to them.

If you are genuinely concerned and unhappy with them doing it, sit them down and have a frank conversation. Explain that you understand that it is their decision, and that you can't stop them, but explain also that you are unhappy with things of that nature going on in your house. Ask, that out of respect for you, they don't browse these particular kinds of sites in your home.

That is the most you can do.
