Hi All
What im trying to do is to connect three diffrent Treeview to the Sql Server in the same Database.
E.g.
Project-Database
ProjecTable1-Table inside Database
ProjectTable2
ProjectTable3
I have tried to connect but only one out of 3 tables will populate the treeview . So i am bit stuck.
If this does not make Sense please contact me craig.mutoko@iondale.com and i will explain.
I need Help Urgently.

I have a very simple requirement.
1. The application takes a list of phrases (could be anything - topics, companies etc.) separated by comma or new line etc.
2. I click 'run', and the application does the following
a) picks each item from the list
b) queries google
c) picks the top 2 results from google
d) goes into the web site that is the result
e) downloads the page to some folder
Is there any utility like this I could get? help really appreciated.

HTTrack[^] is a tool for creating off line copies of web pages.
If that doesn't do the job, the app you have described would be fairly simple to write.
You would load the file in, and build up a list of the queries.
Then loop though the list and build web requests to google for each one.
Parse the response and extract the urls for the first 2 results.
Send a request for the url and save the result to the folder.
If you get stuck on something specific, post a question here and I'll be happy to help.

Depending on how many companies you've got to list you may be banned from Google for a while because it's acting (well is) a bot. Actually one of the easier ways to do this many be on Linux.

Just a couple of hundred - not hundreds of thousands. Would that be a problem as well?

From what I remember the limit is 1,000 for the SOAP API but they're not creating new keys for it anymore (they were free). You can possibly create a local web-page and sign up for the AJAX query stuff to retrieve what you want, alternatively if you don't mind parsing HTML (just had a look at the format of the Google results page and it's pretty clean) you can just use a HttpWebRequest[^] object to form the request and retrieve stuff from that.
Have a search for Html Agility Kit which allows parsing of non-well formed html.

I have one form based program in VC#.
I found the following problem:
when I run it only one time, it takes only about 1 second.
but when I run it 20 times by using a loop, it takes far more than 1*20=20seconds, actually it takes even more than 100 seconds!
I think it may be because some memory or sources are not released during the loop. but I don't how to release the memory and sources for each loop.
I do hope some expert can give me some hints!
thank you very much!!

Post your loop code. I can't help you if I don't know what you are doing.

Hi,
the code is a little bit long, as follows:
simply speaking, I put several buttons in one panel, and each of them represents on function, then I just run the functions from the begining to the end.

Control[] control_panel = this.splitContainer1.Panel2.Controls.Find("panel_buffer", true);

I meant post just the bit of code that does the looping.
1) What on earth is this meant to mean?
Dictionary<string,>>>
You need to escape any < or > signs in your code with < or > before you can post them.
2) Code should be posted within <pre> </pre> tags to make it more readable.
if(testValue)
{
Console.WriteLine("test");
}

Hi, Simon,
by the way, I saw one simulaiton tool, they provide one button to "clear the simulation", then it gives the message "Clearing memory of the simulation". that means the memory used by the simulation has been cleared. I don't know how to clear the memory used by the simulaiton? If I know how to do it, it may help me to improve my own simulation tool, especially when we have many loops.
Do you have the experiences on it?
thank you for your kind help!!

In .net you don't need to clear memory. Most .net objects are "managed" which means their memory is automatically reclaimed by the garbage collector, provided you don't hold references too them after they should have gone out of scope, so you don't need to worry about it.
When a class uses unmanaged memory, it will implement the IDisposable interface. In this case, you just call the Dispose() method when you are finished with it to release the objects unmanaged memory.
I've only briefly looked over your code, but I can't see any types in there that need disposing of.

One thing I like in Java is that their UI elements can all be interconnected around an Action object. You create an AbstractAction with an Icon and a description string, and then you can associate it with any controls, which will all have the same action when activated (click a button, select a menu item, click a toolbar button, etc...), have the same description, and are all enabled and disabled together, all that through the Action object. I haven't tested to see if changing the icon and the description also cascades.
Is there a similar functionality in C# 2.0? Did someone write some class with this functionality? I realize that it's not very hard to code by oneself, but if I can use a proven implementation, or work with someone else, all the better.
EDIT : precised that I want .NET 2.0
This has been added to the framework in C# 3.0, but I must use .NET 2.0

Oh, cool.
Is there anything in .NET 2.0, though? (I forgot to mention that, sorry)

Can't think of anything. (That doesn't mean that there isn't. the framework is too big for me to remember everything). Last time I wrote an in .net 2.0 thought I wrote my own command handling framework, which I used on several projects.

To connect and use the Web Service you can use this URL
https://webservices.innovativegateway.com/IGSPaymentService/IGSPaymentService.asmx
and i have WSDL and proxy class of
web service which is undiscoverable for security reasons.

Hello everyone!!!
Me and this problem again!!! =D
This is my code:
private void lvFiles_SelectedIndexChanged(object sender, System.EventArgs e)
{
ShellLib.ShellExecute shellExecute = new ShellLib.ShellExecute();
shellExecute.Verb = ShellLib.ShellExecute.OpenFile;
shellExecute.Path = @"F:\Painel de Controle ETECH\Projetos ETECH\{0}\80010005.dwg";
shellExecute.Execute();
}
It works BUT open only the file written in the shellExecute.Path statement
I need to find a way to execute a selected file on the list view...
Well I´d many ideas and none worked.. I was thinking to put the selected file on a string and then to put this string on the end of the path statement but I didn´t figure out how to do it and mainly how to put the file name on a string when I select it on the list view control!
Could anyone help me?? I´m very desperate!!!!
best wishes for all!!!

if you mean shellExecute.Path = someString; yes that would be the thing to do.

why not? That is a programming 101 concept. What is your programming background?

shellExecute.Path = someString; and someString represents the path to the file I selected on the listView control. Yes, It means that I´m in the right way now. The problem is right here... select the file in the ListView and put it´s path and it´s name on a string...
I´m a totally dummy with event oriented programming. My knowledge is structured C, Data Structures on C.. I can do an entire B-Tree using C but I can´t implement a simple event.. oh shame on me... =(

How are you populating your listview with the files? Where is the file information coming from?
Each ListViewItem has a Tag property that holds an object. Save your full path to the file in there. When you need it, just cast that ListViewItem's Tag to a string and you've got the file's path.
Alternatively, create a custom ListViewItem that has a Path property, then you can cast the entire item to your class and access the Path property.
public class ListViewItemWithPath : ListViewItem
{
public ListViewItemWithPath(string fileName, string path)
{
Text = fileName;
m_Path = path;
}
private string m_Path;
public string Path
{
get { return m_Path; }
set { m_Path = value; }
}
}
