getting attribute values from AssemblyInfo.cs

25-Aug-03 15:11

Weel another app has to be putting a lock on it or your not releasing a lock. try opening it in word and see if its being held.

I am trying to get assembly info from the AssemblyInfo.cs file, but for some reason I get a null returned for attributes that I specified. Specifically, I provided values for the AssemblyTitle and AssemblyDescription field but both return empty. Any ideas on this ?

public ArrayList GetOmsList()
{
ArrayList drivers = new ArrayList();
DirectoryInfo driversFolder = new DirectoryInfo(dirPath); //direcotry path of drivers
if (driversFolder.Exists.Equals(false))
{
Console.WriteLine("Drivers Path Does Not Exist");
//break out of the following code
}

FileInfo[] allFiles = driversFolder.GetFiles("*.dll");
if (allFiles.Length == 0)
{
Console.WriteLine("No Dlls Found");
}

foreach (FileInfo f in allFiles)
{
string fileName = f.FullName;
try
{
Assembly a = Assembly.LoadFrom(fileName);
Type[] types = a.GetTypes();
foreach (Type t in types)
{
if (t.GetInterface("IDriver", true) != null)
{
object[] attributes = a.GetCustomAttributes(true);
foreach (object attribute in attributes)
{
if (attribute is AssemblyTitleAttribute)
{
drivers.Add("title"+((AssemblyTitleAttribute)attribute).Title);
}
else if (attribute is AssemblyDescriptionAttribute)
{
drivers.Add(attribute);
drivers.Add("descript"+((AssemblyDescriptionAttribute)attribute).Description);
}

}
drivers.Add(t.Name);
Console.WriteLine(t.FullName + " Implements Driver Interface");
}
}
}
catch (Exception e)
{
Console.WriteLine(e.Message.ToString());
}
}

return drivers;
}

I think those two attributes are converted into information in a version resource, and not retained as attributes. You should be able to access them via FileVersionInfo.GetVersionInfo().

Copying data to bytes for sockets

What is the graceful way of moving your data to byte[]'s to be sent over the wire? In C++, I'd do something like this

struct SomeDataHeader
{
AnEnum SomeDescriptiveFlag
DWORD dwDataLength
}

void SendThis(SOCKET &rS, LPCTSTR szData)
{
SomeDataHeader h;
h.SomeDescriptiveFlag = SDH_RANDOMSTUFF;
h.dwDataLength = lstrlen(szData) + 1;

BYTE *pbData = new BYTE[sizeof(h) + h.dwDataLength];
memcpy(pbData, h, sizeof(h));
memcpy(&pbData[sizeof(h)], szData, h.dwDataLength);

Send(rS, pbData, sizeof(h) + h.dwDataLength);
}

(Note that this code is pretty sloppy/probably not right, but you get my idea)

What I'm trying to do is send arbitrary data over the line; What's the best way to do this?

Assuming you have a string:

string dataToSend = "lotsandlotsandlotsofdata";
Byte[] buffer = System.Text.Encoding.ASCII.GetBytes(dataToSend);

Programaticaly select a listview item

Can anyone tell me how to programmatically select a listview item in a windows form listview?

I want to force an item to be selected based upon its text.

Thanks, Smile | :)

The ListView does not have a SelectedItem property.
It has a SelectedItems property but is readonly.
The proper way is to set the item's Selected Property
to true; There are also a bunch of methods to help
Like EnsureVisible( index ), TopItem and so on.

So after I set a listviewitems's selected property to true, how can I programaticaly select that item in the listview?

Is this even possible? I can't find anything on the net about this.

I added listView1.Items[1].Selected=true; to my function and it still doesn't highlight the selected item for me. Is their something I'm not doing correctly?

Make sure you call the Focus() method of the listview after selecting the listviewitem.

lvOfficeNote.Items[0].Selected = true

is how you would do it

I recently wrote a pocket PC version of the game Simon. so far it is coming along nicely, but i still havent incorporated sound into the game! it would be nice to have 4 distinct tones that will play when each of the four colored buttons lights up. i am not sure how to do messagebeeps or any other sounds in C#. also, i dont even know if they will port to the pocket PC properly... any thoughts?!

I think you'll have to use P-invoke for sounds. The following code should get you started. I think it will port to PocketPC, but it may take a little work:

using System;
using System.Runtime.InteropServices;

namespace ConsoleApplication1
{
    class Class1
    {
        [ DllImport( "WinMM.dll" ) ]
        private extern static void PlaySound( 
            string soundName,
            int     hModule,
            int     dwFlags );

        private const int SND_FILENAME = 0x20000; /* name is file name */

        [STAThread]
        static void Main(string[] args)
        {
            PlaySound( "C:\\Windows\\Media\\ChatKick.wav", 0, SND_FILENAME );
        }
    }
}

Server Clustering - MS SQL server

Hi, can anyone tell me anything about clustering? I will need to implement:
1. MS SQL Server clustering (I think I need to configure "virtual node"? I have no idea how to do the implementation. I heard it's also tricky to get server certificate installed in cluster scenario.
2. C#/ASP.NET --> COM+ (Okay, I think I can do COM+ distributed transaction, but not sure how to configure load balancing)

I need some "step-by-step" articles that actually get to the point fast. Any recommendation? Thanks!

Re: Server Clustering - MS SQL server

14-Aug-03 6:45

first of all clustering is an admin thing go to an sql werver site. Unless you are referring to something different "Sql Server Clustering" can be founf in SQL Books Online at the msdn site msdn But I think your talking about something different.

load balancing is done with a load balancing server, you would also want to monitor loads by openeing up performance monitor, com+ mmc and watch the loads, .net has some tools inside the tools menu from the start menu.

If I were you I would go buy a book

Goes over the inner workings of com+ from a c perspective and ends with .NET. Is very useful and explains a lot about load balancing

sounds like you need to read a book just to do clustering and load balancing.

no, don;t think there's much information in regards to SQL server BOL.
