Another point to add.
Your original method, initializing the member field to a valid value when accessed, is a technique called "lazy initialization" and is good for initializing objects that may have a heavy penalty such as in time or memory usage. For example, if your object contains a large collection that is not used in say 50% of the cases, you can put off initialization until it is needed. Or if that collection may take time to initialze, may be populated from a database, you can put it off until after the object has been created.

Hi,
I have got a public key token, and want to remove/unregister all assemblies from GAC having that public key token, does any one know about it?

Hi,
I don't know easy solution, because Gacutil can't uninstall assembly by PublickKeyToken (or may be I don't know how to do this). I think you can prepare script (on Python, for example), which will start 'gacutil /l' command and take list of all assemblies in GAC. After that you can parse these results, because they contain Assembly name and Public key token, and take list assemblies' names. You can use this list to call 'gacutil /u' for removing of all these assemblies.

.Net framework will work perfectly in the higher version of windows 2003 and above.
If you want to work on the .Net Framework please install Vista or XP that will be be safe.
And also check the RAM if you have 1gb Min it will be good.

There are no Excel snippets in the ones that come with VS, I'd say they are part of the Visual Studio tools for office.

Hello
Is it possible to make a reference to an appliaction that is already running
and then take control of this application in .Net ?
I was looking today at the SHDocVw.dll (internet explorer) which provides a class
that when initalised represents a collection of all the running IE instances. You
can then iterate through the collection to find the instance you want, set
an IE object equal to it and then programatically control the window.
I'm wondering now if there's a more general class that can represent all running applications.
I looked at System.Diagnostics.Process.CreateObjRef() but.....
Thank for reading

You can get the processes running by using
Process.GetProcesses
So you could code
For each item as process in process.getprocesses

Hi everyone,
i need a little help. So im trying to creat an exception policy with logging without using *.config file. Im using all the classes i need like : TraceListener, TextFormatterData, EmailTraceListenerData etc., but my problem is that i dont know the steps(the algorithm) for creating a policy without the *.config file? Can somebody help me?
Thank you in advance!

To originSH : Thanks but i cant find the place for this code. If you dont mind see what i already wrote :
catch (SqlException ex)
{
TextFormatterData emailTextFormatterData = new TextFormatterData();
emailTextFormatterData.Name = "Text Formatter";
emailTextFormatterData.Template = "<template>

Does anyone know if it is possible to call a web service to return some data and after the data has been returned the web service carreis one fetching more data. So it starts a new thread that carries on after the call has been completed?
I am trying to write a web service to retrieve data from the database that can return the first page only on large data sets and then fetch the rest into cache after the call, so any subsequent pages will be fetch quickly.

Hi,
I have C# GUI that use managed C++ dll. the managed c++ dll calls unmanaged c++ dll. The three projects compile and link correctly.
but I have the following run time exception:
"The specified module could not be found"
Somewhat, the unmanged C++ dll could not be read. Any idea why I have such error?
Thank you.

Perhaps your program can't find the unmanaged dll.

I have a set of class all deriving from the same interface, iVendor. Now I have a user control that I am formatting according to the type of VendorClass that it will be assigned via a property. The problem is the following: My middle tier is returning a generic Collection that is returned from a generic function. So my function signature is as follows:
public static Collection<t> GetVendors<t>(eDataDetail eDetail, int Contract_ID, ref ContractsException oCEExecption,
int startRowIndex, int maximumRows, out int TotalRowCount) where T : iVendor, new()
I'm trying to assign the result of this function call to a property on my usercontrol with a signature of :
public List<ivendor> Vendors
{
get { return this._oLVendors; }set { this._oLVendors = value; }
}
I'm trying to make the assignment as follows:
ctlDemographics.Vendors = new List<ivendor>(Contract.GetVendors<contractvendor>(Contract.eDataDetail.Basic, this.ContractID, ref oCE, 1, 300, out TotRowCount));
SInce there is no such thing as Generic properties can someone explain how I would go about handling this?
Thanks

Hi Santiago,
You could do this;
class MyClass<t>
{
private List<T> _list = null;
public List<T> Prop1
{
get { return _list; }
set {_list = value; }
}
or if you have a known base class or interface of the types to be stored on the List
you can do this:
public interface iInterface{}
class MyClassA:iInterface{}
class MyClassB:MyClassA{}
class MyClassC:MyClassB{}
class MyClassD
{
private List<iInterface> _list = null;
public List<iInterface> Prop1
{
get { return _list; }
set {_list = value; }
}

Using your example I have :
using SCG = System.Collections.Generic;
SCG.List oColl = new SCG.List();
oColl.Add(new B("Michelle"));
oColl.Add(new B("Chris"));
oColl.Add(new B("kathy"));
this.Prop = new SCG.List<iclass>(oColl);
public SCG.List<iclass> Prop
{
get { return new SCG.List<iclass>(); }
set { }
}
I get an error on line:
this.Prop = new SCG.List<iclass>(oColl);
Error is:
Error 1 The best overloaded method match for 'System.Collections.Generic.List<webapplication1.iclass>.List(int)' has some invalid arguments C:\Projects\ConsoleApplication1\WebApplication1\Default.aspx.cs 26 25 WebApplication1

This error could be because of a type mismatch - but since the type used for list is not given in your examples it's impossible to tell.

I think I found the solution: COnvertAll method of the COllectionBase Collections.
//Collection to list
SCG.List oColl = new SCG.List();
oColl.Add(new B("Michelle"));
oColl.Add(new B("Chris"));
oColl.Add(new B("kathy"));
SCG.List<iclass> ListA = oColl.ConvertAll<iclass>(new Converter<b,iclass>(ConverttoIClass));
public static iClass ConverttoIClass(iClass obj)
{
return (obj as iClass);
}

FOund the solution using PowerCollections Algorithms class:
ctlDemographics.Vendors = new List<ivendor>(Algorithms.Convert<contractvendor, ivendor="">(Contract.GetVendors<contractvendor>(Contract.eDataDetail.Basic, this.ContractID, ref oCE, 1, 300, out TotRowCount), Vendor.ConverttoiVendor));
Had to create a Convert Delegate, very simply:
public static iVendor ConverttoiVendor(iVendor oV)
{
return (oV as iVendor);
}
THen just pass that to the constructor of a new generic List<>.
