ListView.HitTest returns an object that contains a reference to the ListViewItem AND the ListViewSubItem that was clicked.
If it was the first column, those will be the same; for subsequent columns, it will contain the correct item. You'll have to do some checking on those objects as it sets them to null sometimes and I forget now what the exact conditions are.

Hello everyone,
I am trying to create my own ContextMenu for a button in my Windows Application. The following is the code that I am using to have the ContextMenu. I was wondering how I can assign click event to the options in the ContextMenu?
MenuItem[] menuItems = new MenuItem[]<br />
{<br />
new MenuItem("Button Info. 1"),<br />
new MenuItem("Button Info. 2"),<br />
new MenuItem("Button Info. 3"),<br />
new MenuItem("Exit")<br />
};<br />
ContextMenu buttonMenu = new ContextMenu(menuItems);<br />
buttonMenu.Show(btnTest, new System.Drawing.Point(70, 30));
Thank you very much and have a great day.

Hi,
ContextMenu behaves like other menus; you can add MenuItems to it as you wish.
So I suggest you create one MenuItem, set all its properties, add it to the
ContextMenu; then continue with the next one.

You should not use a picture box, just draw your image in a paint event handler.

hi i have a webservice in vs2005, and i am trying to access that from my vs2003 application.
To service methods are defined onr is "helloworld",default method.Its working properly
But in my next method i am trying to return a datatable.
But it showing some error on running
the exception is aditional information: Method Service.GetAction can not be reflected.
GetAction is my method.
this is the reference class
/// <remarks>
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://tempuri.org/GetAction", RequestNamespace="http://tempuri.org/", ResponseNamespace="http://tempuri.org/", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public DataTable GetAction() {
object[] results = this.Invoke("GetAction", new object[0]);
return ((DataTable)(results[0]));
}
/// <remarks>
public System.IAsyncResult BeginGetAction(System.AsyncCallback callback, object asyncState) {
return this.BeginInvoke("GetAction", new object[0], callback, asyncState);
}
/// <remarks>
public DataTable EndGetAction(System.IAsyncResult asyncResult) {
object[] results = this.EndInvoke(asyncResult);
return ((DataTable)(results[0]));
}
I changed the datatype to datatable.
My small attempt...

First and foremost you can't return datatable from web method rather return dataset containing databale !!!!

Ya i tried to return one dataset from service it was a success.
But in the webmethod i am trying to get a dataset by executing the query, by creating the instance of another class.But it gives an exception.......
[WebMethod]
public DataSet GetAction()
{
DataSet dt = new DataSet();
DataLayer.WebSrevice webser = new WebSrevice();
dt = webser.GetActiontable();
return dt;
}
it will work if i remove
DataLayer.WebSrevice webser = new WebSrevice();
dt = webser.GetActiontable();
this lines, ie i cant access the other project from the service class
My small attempt...

Hi
I have few doubts, as I am going to release my app:
1. My application developed in C# VS2005 needs .Net Framework to be installed in PC.So, if the user runs the app, is there any way to detect for framework , prompt and start downloading .Net Framework from Microsoft?
As it is very frustrating for user to go to website , search and download.
2.I need to change the host file in PC , ex:192.168.51.150 something.com.
Can it be done programmatically??
Immediate reply is appreciated.Thanks in advance
Aruna

1 - If a PC does not have .NET, I believe it will just crash, you need to provide an installer that also installs it.
2 - If you have permission, you can write to any file on the PC. Which means, if it's Vista, you won't have permission

In Visual Studio, right-click your solution and select Add New Project. For the project type, find the Setup Project (it should be under Other Project Types-> Setup and Deployment)
One of the things you can do in such a project is specify prerequisites. One such prerequisite will be the .NET framework. You can tell it to download the prerequisite from the vendor's website - in this case, it will automatically know where to download the .NET framework from.
If this isn't enough detail, there are several very good articles on this website describing how to do this in extreme detail.
*****
For the hosts file, you may want to consider not making that edit. While (on XP) nothing stops you from doing so, it is considered by some antivirus and anti-malware programs to be virus or malware-like behavior and it will be immediately stripped out.
Unless you can guarantee that the end user's system won't do that, you shouldn't rely on it.
Unless there's some convincing reason you actually MUST use a hostname, it might just work better for you to use the IP address.
But yes, this can be done programatically. The hosts file is just a file on the computer like any other and edits to it take effect immediately. It is located at %SYSTEM%\drivers\etc\hosts, and the best thing to do is probably just append a line at the end so as not to alter any existing custom hosts (for example, I put some in there sometimes when websites I'm working on haven't resolved through DNS yet).

Thanks for your detailed reply.Its working fine.
But I have one more doubt regarding memory usage.When I run the application the memory is 170 000K, when I minimise the app, it drops drastically.
Is it ok?I heard the task manager does not show accurate memory usage.
Do I need to take any action?
Or in the start of the program, do I programmatically minimise the form and maximise again?
Please clarify my doubts.
Thanks

The way I see it, you have two options
1 - post an article on this site ( that would rock )
2 - pay for advertising ( really, you'd only choose this if your code was not 100% and unencumbered ).
Either way, thanks for supporting the site, and not spamming it again.

I would love to write some articles that show how to use the free Krypton Toolkit. I didn't think that was allowed; because although I can provide the install for the Toolkit, and the Toolkit is free even for commerical use, I cannot provide the actual source code. Would it be ok to provide just the build?

OK, I'm not sure about that, I'd suggest writing to Chris and asking him.
