Capturing Trace messages

Ok, I'm ignorant here. Y'all know about DebugView, from SysInternals, right? How do I capture the output of Trace.Write... messages in another application, the way DebugView does?

Thanks!

There doesn't seem to be any easy way to do this. Capturing debug/trace output for just you r application is easy, just derive a class from DebugListener/TraceListener and add it to the list of Debug/Trace listeners using Trace.Listeners.Add method. But capturing output from other apps seems to be quite difficult to do.

This[^] CP article might help. Also this[^] might help.

Have a look at DBMon. It was an SDK tool with source code back in the day.

It can be downloaded here[^] or you'll probably have it in your platform sdk installation.

localization question -- maybe Heath knows????

Is there any way that I can start with a 2-character string, and find out if that is a valid 2-Character, ISO code for a localized language? For example, I have 'es' and I want to know that this is valid because it is the 2-character code for spanish. But 'oh' is not a valid language code.

There are 10 kinds of people in the world.

Those that read binary...

...and those who don't.

System.Globalization.CultureInfo.GetCultures();
Loop though the cultures and see if you find the two letter ISO code.

Obviously the two letter codes are not enough to identify a language, so be careful what you do with it.

Data in DataTables

Hi all,

I have a DataTable object and the 4th column has DateTime objects stored in it.
To get at the DateTimes i am doing the following.

DateTime dt;<br />
<br />
for (int x = 0; x < Table.Rows.Count; x++)<br />
{<br />
    dt = (DateTime)Table.Rows[x].ItemArray[3]<br />
    .....<br />
    Some other code here<br />
    .....<br />
}

Is there any way of getting at the DateTime object in the column without casting?
This is my biggest overhead by far in the method which is fine for a few hundred iterations
but sometimes i am going through tens of thousands of iterations and it's a tad slow.

Anyone able to help??

Cheers

Kev

When using the DataTable you will have to do the casting. One solution would be to take another data structure. You should also try not taking the ItemArray property as I think it produces a bit overhead (Im not 100% in this):

DateTime dt;

for (int x = 0; x < Table.Rows.Count; x++)
{
dt = (DateTime)Table.Rows[x][3]
.....
Some other code here
.....
}

Get IP Address

Anonymous9-Jun-05 3:36

Say someone wanted to write an application that would get the ip address, like an IP Updater. I have found various examples on the how-to of getting this information using the .NET dns class but here is the problem - how do you get the public ip address of a machine when it is behind a router? The using of the .NET dns class, in my experience, will retrieve the local ip address, thus the 192.168.1.X address, not the public ip address of 66.xxx.xxx.xxx. How can I retrieve the public ip address?

Re: Get IP Address

Best is to use a webserver/service, and get the client to access that. That will give you the last public IP.

Dave Kreskowiak9-Jun-05 8:16

Your machine doesn't have a "public" IP address. It only has the address assigned by your router.

Like leppie said, you can use an Internet webservice or website that tells you what your routers WAN address is because it's your router that make requests for your machines, kind of like a proxy. The address returned will be the same for all computers on your network because the address doesn't belong to any one machine, it belongs to the WAN side of your router, or you can think of it as your network's address.

Or, you can use the hostname and domain that was assigned to you by your ISP, if available (check your paperwork) and DNS resolve that.

Another option would be to query your router for that information. You can either write yourself an automated Telnet client that talks to the router, or your could write up something to do it through the routers web interface. Either way, the code you write will be specific to YOUR router. It won't work with all manufacturers because each one uses a different interface. For example, the code that works on getting the WAN address for a D-Link router won't work with a Linksys router.

Convert Hex strings to Long/Decimals?

Chua Wen Ching9-Jun-05 3:33

Chua Wen Ching

9-Jun-05 3:33

I have a problem. But on .NET 1.1

My Scenario:
Actually I will have a string of hexadecimals read from a xml file. Then from the hexadecimals, i will add 1 value whenever i made any modifications. But just i do not how to get started. It is like an incremental hexadecimals.

I have a string of hex.

string strHex = "0100000000FF";

I want to convert this Hex to decimals, just like the windows calculate, when you type FF in Hex and click on Dec radio button, it will change to 255.

I tried string.Format("{0 Big Grin | :-D

}", strHex);

I tried Convert.ToDecimal or Convert.ToInt64

But i still cannot find a solution?

----

I know how to convert long to hex. Like this.

for (long x = 000000000000; x <= 281474976710655; x++)

{

Console.WriteLine(string.Format("{0:x12}", x));

Console.ReadLine();

}

But i do not know how to do the opposite? Anyone can help me please?

Thanks.

You need to manually loop through your Hex string, a byte at a time and convert it to decimal. Like this

byte []hexValues = new byte[text.Length /3 + 1];
			
int index = 0;
for (int i = 0; i<text.Length; i += 2, index++)
{
   string currentHexValue = text[i].ToString();
   if ( i + 1 < text.Length)
   currentHexValue += text[i+1].ToString();
   try
   {
	hexValues[index] = byte.Parse(currentHexValue, System.Globalization.NumberStyles.AllowHexSpecifier);
   }
   catch(Exception)
   {
      if (currentHexValue == "00")
	return new byte[] {0};
      else
	// Throw exception
   }
}

Hey

I created an application that uses the DocumentComplete event.
on my computer it works great, but on 2 other machines I checked my program it does not work, and completly ignores the event.

I checked the automation article's tutorial demo, that uses the same event (great article by the way!), and the same problem appears again! on my computer it works great, but on 2 other it does not, and completly ignores the event.

ANY IDEAS ANYONE????
Thanks alot!

There's more information about the problem in this[^] MS KB article. This is a limitation of the underlying unmanaged API, not the .NET wrapper class.

If you want to select more than 200 files, you'll have to design your own OpenFileDialog box.

11-Jun-05 17:26

I also think about this. But when you do it, you can only do a little work, for example change 200 files to a larger number and remove unneccessary funtionalities, and what remain is VS.NET's work.
How do I get start?

Re: How can I design my own OpenFileDialog?

Dave Kreskowiak12-Jun-05 4:06

12-Jun-05 4:06

No, you can't do that. You must write your own OpenFileDialog from scratch.

You can't change the existing dialog because the problem is NOT within the .NET Framework OpenFileDialog class code. The problem lies within the underlying Windows control, which you cannot change, that the .NET Framework OpenFileDialog class wraps.

SelectedPath() not working in FolderBrowserDialog

Anonymous9-Jun-05 1:27

Anonymous

9-Jun-05 1:27

I have the following code:

//Create an FolderBrowserDialog
FolderBrowserDialog folderDlg = new FolderBrowserDialog();
folderDlg.RootFolder = Environment.SpecialFolder.MyComputer;
folderDlg.ShowNewFolderButton = false;
folderDlg.Description = "Select the folder"; 
folderDlg.SelectedPath = strPath;//which is defined earlier and is checked to be a valid path
			
DialogResult result = folderDlg.ShowDialog();
if( result == DialogResult.OK )
{
   //some code here
}

However, when the FolderBrowserDialog is shown, the initial folder is not set even though SelectedPath property is used as above. Similar experience is noticed by me in some other code on similar occasions as well. In fact, in this situation, there is some other abnormality as the OK button is shown enabled for My Computer folder also which is not so when this property is not set. On the other hand, if I set the SelectedPath property as something like @"C:\Program Files\", then it is correctly shown.

What can be the reason? Am I missing something?
