It's your database that is out of date, and your database that is the issue. The database needs to tell your program when it's been changed, or you need to keep asking, those are the two options.

If your implementation utilises BindingSource there are several events that you should consider investigating.
BindingSource.CurrentChanged
BindingSource.CurrentItemChanged
BindingSource.ListChanged
The last of these is most likely to be of use to you.
Here[^] is a link to the BindingSource reference on MSDN. I am struggling along on 53.6 Kbs at the moment otherwise I would have given links to the events themselves. 
Hope this helps.

I want to gather the Mac address in the diffrent subnet.
Now,My programe(C#) can obtain the PC and Printer's Mac address by SNMP.
But i can not obtain the switches' Mac address by the programe.

isn't it?
Maybe there are some forbidden in my VLAN.it is right?

Hi,
I am working on shared add-in in c# for Excel. Let us consider 3 components A,B,C. Where A is a Shim,B is Shared an add-in(used IDTExtensibility interface) which creates all tool bars, menu items for Excel and C is an automation add-in which contains UDFs.
I have static property in Automaion add-in(C) which set/gets Excel Application object. Whenever OnConnection(..) of shared add-in is called from the framework, I am setting the Excel application object using this property. So When I type some UDF in Excel, it uses this Excel application object for further work on Excel.
Recently I tried to remove the Shim and put the VSTO on it. When I use VSTo, it doesn't use shared add-in.Here also I set the Excel application object by using static property. Now I have I enabled this Auotomation add-in(add-in->Options->Automation Tab).But when I type some UDF in Excel cell, excel object is not available that is set from VSTO.How do I pass reference to Excel object to Automation add-in so that the same Excel Object is available in Automation add-in when we type some UDFs.
What I observed here is VSTO and Automation add-ins are working in different AppDomains.
Please help me.
Thanks.

Thank you jasome.
I googled the "Winsopller.drv",i have not found it.
is it "Winspooler.drv" or "Winspool.drv" which one is right?
By the way the printer is not connect with my PC,
it is in another subnet,
For Example my IP is "192.1.168.5"
The printer's IP is "192.1.167.23".

Hi,
I'm trying to get WebDAV implementation using some open source called Sphorium and Casinni Webserver. It is able to reach the destination folder but some time i'm getting the following error.
"Documents in this folder are not available. The folder may have been moved or deleted, or network problems may be preventing a connection to the server."
What could be the cause?

You are more likely to get an answer if you post in the correct forum. Try Web Development (look at the side-bar to the left for forums list)

Check Directory Browsing permission. You must set directory browsing permission to true. This will allow to get it a list of files/folders.

Hi ,
What is the advantage of using IList over List in C# ? what is the difference between List and Ilist ?
Thanks,
Azeez
|
|
|
|
|
List implements IList. It takes the features of IList and implements them. Also, you can only actually create a List - IList is just a contract, or an Interface. So, List is better.
|
|
|
|
|
If you take a normal List<T> and call it's AsReadOnly method then it returns an IList<T> , so I assume an IList can be readonly whereas a List can't. I've never looked into it so I could be wrong... just an observation I made a couple of months ago and figured I'd investigate one day!
|
|
|
|
|
IList is an interface from which all lists derive from. So, while List is an IList, the opposite is not true.
If you need a normal list, use the List class, if you need to build your own list with custom behavior (such as read only, for example), derive from IList.
If you want your method to accept as parameter different type of list from the standard one, use IList as parameter type.
If you want to hide the specific list type your method is returning, use IList as return type.
|
|
|
|
|
Flexibility.
A method that accepts a List can only accept a List (or something derived from List), whereas a method that accepts an IList can accept anything that implements IList, not just List.

Hi,
I want to change icon of any type of setup (exe) file through code.
Thanks.
|
|
|
|
|
I doubt you can. The icon is embedded in the build. You would certainly need to change the icon of ANOTHER program, not the one with the code in it. Or do you mean the icon that's shown on the taskbar ? That is a property you can set in code.

How can I embed the icon at the time of building, through the code.

Why do you want to use code, instead of the project settings, like everyone else ?

I think he means the latter, English isn't everybody's first language 
Of course, there's the possibility he's a cretin, but I'm willing to give him the benefit of the doubt.

Well, I answered in such a way as to make the answer clear, but also to ask him, if he meant what he said, why he is intent on using code to do it.

Hello Friends,
I have inherited the DataGridViewColumn class and add new property in it.
I am able to see myClass and its property in DataGridView but when I set the value to my property, it is set to null automatically. Here is my class :
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
namespace dataridviewColumns
{
public class DataGridViewFinderColumn : DataGridViewColumn
{
public DataGridViewFinderColumn()
{
this.CellTemplate = new DataGridViewTextBoxCell();
this.ReadOnly = true;
}
private string _Caption;
public string Caption
{
get { return _Caption; }
set
{
_Caption = value;
}
}
}
}
Thanks and Regards,
Rahul
