Try a Google search, there are quite a few sites that can find this information for you. I think one of them may even be called "whatsmyip.com".

IMO the only reliable way is by asking the external world. Here[^] is one of many sites that may help.

I wrote a command line tool in C# (code included) that will use a service on my server to pull external IP.

Hi , have a good day ,

I have an Indicator Weight connect to COM port on My Pc ,

When I press the "Print Button" on the Indicator it sent weight to the Com Port ,

And I receive the data by this events :

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
     TxtOutPut.Text = serialPort1.ReadExisting();
}

So far so good ,

The Only problem I had is that When I press The "Print Button" on the indicator "
The DataReceived Firing 5 times , Before all the data sent , For Example :
The indicator Show The Weight on it's screen Like "US,NT 4.590 KG"

so When I press "Print Button" On the Indicator its Sent :

1) US,NT --- DataReceived Firing ,
2) Space --- DataReceived Firing ,
3) 4.590 --- DataReceived Firing ,
4) Space --- DataReceived Firing ,
5) "\r\n" --- DataReceived Firing ,

I think It's Must Sent the Weight as a whole , ( as Other Indicators Works ! )

Any Suggest Would be Appreciated !

Hi,

you should use the "ReadLine" method instead since it reads the response until it receives a "NewLine" (\n).

Try:

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
   TxtOutPut.Text = serialPort1.ReadLine();
}

The alternative is to wait a while inside the DataReceived handler, so more/all data can come in before you get it all. Say 100 msec.

Or, if you need it fully event driven, start a timer in DataReceived, and read in the Tick handler (don't forget to stop the timer again).

Hi, thanks for your response,

is it possible to use c++ classes from C++ DLL in C# without making wrappers.

i also read this article and other many article, all the article tells i need to make a wrapper for everry class and its members to use in C# project.

if wrapper is only solution than i want which approach will be best like managed C++ wrapper and unmanaged C++ wrapper

Thanks
Bankey

If possible you can also rewrite your C++ code to managed C++. This can even allow you to use the same source for unmanaged applications and for managed ones. At work we have such a kind of library that uses a lot of compiler switches to determine if the code is to be used with .NET or not.

No, since the C++ classes are not managed code. Your either need to write a wrapper around it or rewrite the C++ code in C++/CLI (Managed C++). Which you chose is entirely up to you.

So I am trying to give the user an option of removing registry keys when uninstalling my application (the installer is the windows installer with visual studio).

The problem is it appears the message box appears behind the uninstaller (sometimes). Here is what I am doing:

public CustomInstaller() : base()
{
    InitializeComponent();

    base.AfterUninstall += new InstallEventHandler(CustomInstaller_AfterUninstall);
}

public override void Uninstall(IDictionary savedState)
{
    base.Uninstall(savedState);
}

void CustomInstaller_AfterUninstall(object sender, InstallEventArgs e)
{
    // Ask to remove settings
    DialogResult result = MessageBox.Show("Do you want to remove all settings? (This is not reversible)", "Remove Settings",
        MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (result == DialogResult.Yes)
    {
        try
        {
            Registry.LocalMachine.DeleteSubKeyTree(@"Software\JD Development");
        }
        catch (Exception ex)
        {
            MessageBox.Show("Unable to remove registry settings: " + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

    // Delete the service
    Process.Start("sc", "delete JDAgent");
}

I googled (you can do this too) and found some solutions:

1.:

MessageBox.Show(new Form(){TopMost = true},"I'm still on top, YEAH");

2.:
TopMost MessageBox[^]

3.:

[DllImport("user32.dll")]
public static extern int MessageBox(int hWnd, String text, String caption, uint type);

Then just call MessageBox with MB_TOPMOST

Yeah I was working on this late night and didn't find anything. Just had my wording screwed up in my search parameters instead of just top most messagebox. I dunno. Thanks for the reply.

Problem with reading a csv file

benams25-Nov-10 5:33

25-Nov-10 5:33

I create my own csv file via Microsoft Excel 2003, then I need to read it with my c# application.
It's impossible to read it correctly because the fields are separated by a comma and I have some fields that include commas which are not supposed to be separators.
I have heard that csv separators could be also TAB chars.
Is it possible to save the CSV file with tabs instead of commas as separators?
Is there any other way I can solve the problem?

Thanks from advance,
benams

Dave Kreskowiak25-Nov-10 5:54

I would suggest using a third party library, like this one[^] to parse the CSV. The code you're using doesn't take into account that string fields in a CSV should be enclosed in quotes if the field contains the seperator character. If you wrote this code, you're not tracking the use of quotation marks properly, if at all.
