I'm not going to give you the answer but only because you put regions inside of methods.

What sort of answer is that, he can have regions inside a method (NOT), how about nested regions and regions from the middle of one method to the middle of another method. I must admit I have never seen regions used inside a method

this.NotifyIcon.BalloonTipShown not executing

I'm trying to build a pop-up graph in c# using this.NotifyIcon.BalloonTipShown but it doesn't execute in Windows 7 . Is there any alternative way to open a form when the user hovers the mouse over the icon and close the form when the mouse is moved away ?

Im using the code below

// 
            // NotifyIcon
            // 
            this.NotifyIcon.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info;
            this.NotifyIcon.BalloonTipText = "RapidNAS Warez Made Easy ...";
            this.NotifyIcon.BalloonTipTitle = "RapidNAS";
            this.NotifyIcon.Icon = ((System.Drawing.Icon)(resources.GetObject("NotifyIcon.Icon")));
            this.NotifyIcon.Text = "RapidNAS Warez Made Easy ...";
            this.NotifyIcon.Visible = true;
            this.NotifyIcon.BalloonTipClosed += new System.EventHandler(this.HideGraph);
            this.NotifyIcon.BalloonTipShown += new System.EventHandler(this.ShowGraph);

private void LaunchDownloadStatus(object sender, MouseEventArgs e)
        {
            Popup form = new Popup();
            form.Show();
        }

        private void HideGraph(object sender, EventArgs e)
        {
           
        }

Properties.Settings (Application connectionstring)

I have a connectionstring that is a Application setting and not a user setting. I want the user to be able to change this, but the datasets seem to want an Application Setting. IS there a way to programmically change this setting?

Nevermind. I just changed it to a USER setting and went into each dataset and changed where it looked for the connection string

Convert XDocument to string ?

Hi.
How can I convert a XDocument variable to string ?
Using ToString() method is the true way ?

xDocument.ToString();

Thanks.

Well, in XDocument, ToString() is overloaded to give you the XML string representing the document, so I think the answer is yes.
If you want to remove unnecessary white spaces and carriage returns, you should use xDocument.ToString(SaveOptions.DisableFormatting);

You should also have a look to the Save() method, that can write the XML on a more general target (a file or a stream).

Recommend a simple distributed messaging tool?

Brian Duke6-Jul-09 5:23

I'm looking for a simple tool to replace MSMQ, mainly because of the centralized, single point of failure nature of MSMQ. Currently, we have a web server farm and some of the sessions will have to communicate through MSMQ. The problem with this is that if the machine where the queue is defined is down, the messaging stops. Can anyone recommend a tool that is distributed among the servers so that I can send a message to a queue and if a session on another server is listening it will receive the message? The idea is not to be sending a message to a machine based queue such as in MSMQ, but more of a virtual queue that is alive as long as something is listening on it. I was hoping to find something like this so we don't have to write one ourselves.

Thanks
Brian

Application problem

Hi,

I don't know if it's the right forum but it seems to me the most appropriate.
I have an application developed in C# (VS 2005) that work fine on Windows XP.
The application used the TFTP.exe installed on Windows.
now I moved to Vista and discovered that TFTP.exe is not installed by default and some configuration are required.
My question is:
Is it possible to detect (when application setup is running) that the TFTP.exe is not installed and to install it during the setup of my application (to avoid the user to do this manually)?
If yes, how can I do that?

Regards,
Lune

You could prolly check whether the executable exists. Are you thinking of distributing the TFTP.exe with your application?

If it's part of Vista, wouldn't the user need his original installation CD, in order to add the extra features?

No I don't want to distribute the tftp.exe, as you can see in the link http://www.simplehelp.net/2008/09/10/how-to-install-a-tftp-client-in-windows-vista/[^] it's a kind of configuration.
I would like to avoid this configuration to the user and so ask if it can be done by software.
Thanks

Seems that it's a part of Windows itself. Windows XP would require the user to have his/her installation-media at hand - because your changing the configuration of the Windows-installation. I don't know if Vista has the same requirement.

In short; it's not a setting (it's not comparable to the screen-resolution setting) but a feature that may or may not be installed.

XML to LINQ

hi all

i have an xml file as:
<?xml version="1.0" encoding="utf-8" ?>
<Pages>
<Page>
<Name>ManageUser.aspx</Name>
<User>
<ID>Admin</ID>
<ID>WebMaster</ID>
</User>
</Page>
<Page>
<Name>Traders.aspx</Name>
<User>
<ID>Admin</ID>

</User>

</Page>
</Pages>

my query as:

var result = xmlDoc.Descendants("Page").Select(s => new { Name = s.Element("Name").Value, User = s.Element("User").Value }).Distinct().ToList();

and finally result as:

result |Count =2
+[0]   {Name="ManageUser.aspx",User="AdminWebMaster"}
+[1]   {Name="Traders.aspx",User="Admin"}

My problem is that how i can sub divide "User" into "ID"
like

result |Count =3
+[0]   {Name="ManageUser.aspx",User(ID)="Admin"}
+[1]   {Name="ManageUser.aspx",User(ID)="WebMaster"}
+[2]   {Name="Traders.aspx",User(ID)="Admin"}

actually i want IDs against Pages

thanks Smile | :)

Try this:

              from id in page.Descendants("ID")
              select new
              {
                  Name = page.Element("Name").Value,
                  ID = id.Value
              }).Distinct().ToList();
