You need to write a recursive function, that is, one that 'collects' all the directories within your main one, and calls itself for each, so it keeps drilling down.

How do I get all the ones below that one, and below that one and send them to an array?
By doing a recursive call like this:
public ArrayList Directories(DirectoryInfo startDir)
{
ArrayList list = new ArrayList();
DirectoryInfo[] dirs = startDir.GetDirectories();
foreach(DirectoryInfo dir in dirs)
{
list.Add(dir);
list.AddRange(Directories(dir));
}
}
See how the Directories() calls itself, but for the subdirectory.
Does this help?

yeah, thanks! I was gonna try to use a while loop, but that could get really complex logic-wise. but the foreach thing is really handy. thanks!

actually, there are two more arguements I just found out about. One that you can tell it to search ALL the subdirectories. but I still thank you for your time in answering my question.

I have some Problems please Help Me.
I am using Visual Studio 2002.
1. I want to display Images in Menu/Context Menu.
2. How to Hide taskbar and Desktop Icons.
3.How to Make form Topmost.(condition is that without closed that form you cannot select other items(forms).
using visual C#

1. I don't think there is an easy way to do this, but I could be wrong. Does the menu have an ownerdraw option ?
2. I don't think you can hide desktop icons at all, but any option you have will involve pinvoking shell functions. www.pinvoke.net is the best place for info on that stuff.
3. In C++, SetWindowPos made your window topmost, I'm not sure how else to do it in C#. Do you mean topmost, or do you mean modal ( where a dialog stops the rest of a program ) ? ShowDialog is how you get a modal dialog up in C#.

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.

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.

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
.....
}

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?

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.

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 }", 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
}
}

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!
