Whats wrong with mouse move event in the container of the button? You may need to handle the event for a number of containers/controls but you have half the problem and now have the other half.

No.
Use a generic List instead. Don't post back asking what a generic List is, Look it up.

Have a look at my ball simulation using a quad tree.
Hoping to set up multitasking to get more FPS

let me know what you think
Cheers,

I think people are unlikely to download an exe like this. You'd be better writing a blog or article demonstrating your code.

Good point.
Here is the link for the source.

I wont go into to much detail.
Just have a look at the code.
All the balls are split into there corresponding grid spaces so collision checking can be made faster.
Should be able to run 3000 balls at about 10fps

cheers

I want to display a list view that will contain data as follows:

Column 1 will display normal text data, column 2 will contain multiple images and every image will have a click event.
How can I do this?

Use a datagridview - I'm pretty sure you cannot add multiple controls (picturebox) to a cell though. Feels like a custom control requirement to me.

Hi guys!
Does anyone know of a replacement for the FlowLayoutPanel control that supports VirtualMode and selection of items? I guess I could make one myself, but I was hoping someone already did this before. What I am really looking for is a control that has the functionality of a ListView but supports templating controls like FlowLayoutPanel.
Thanks

hi
i developed a project in c# and the final ouput is generated in crystal reports and created a setup of project and installed in client system and i separately installed crystalreport setup which i downloaded from net.

now my problem is...
my client is to install two setups in each system
1)project setup
2)crystalreport setup

can we combine these two setups and make a new setup which installs my project and crystalreport exe

Did you try adding the Crystal Reports merge module to your deployment project?

Or you could check the prerequisites box for CR if you prefer.

m_Timer = new Timer();
m_Timer.Interval = 5000;
m_Timer.Tick += new EventHandler(m_Timer_Tick);

}

try
{
if (listView1.Items.Count > 0)
{
y = listView1.SelectedItems[0].Index;
//m_Timer.Stop();
m_Timer.Start();

catch (Exception ex)
{
MessageBox.Show(ex.Message);

Wow - that's about the worst thing you can do.

1 - you don't show us any code
2 - you ask us to provide a full solution
3 - you tell us you need it quickly

We don't work for you. We help you for free. We do this despite the fact that increasingly, the people asking here are clueless to the point of not even being able to understand good answers.

If you want each item to have it's own timer, then you need to create a timer for each item. It sounds like you're only creating the one.

It may be appreciated, but it's not going to be forthcoming in the way you want.

Well, that's the name of this forum so at least you got that right. Unfortunately for you though, you aren't my boss so I'm proceeding to urgently not writing the code for you.

Yes - you can set timers on every selected item, and you'd then handle the timer events for each one. It sounds like you want to create a list of timers and deal with them like that.

thanks Pete if possible can u kindly help with the code whenever possible at ur pace.......i hav posted the code i hav done.....what i am doin is that i am first manually adding numbers to the listview and then on select index change i hav set the timer....

I knocked this quick sample together, and it should do what you want:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace SimpleWinApp
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();

      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");
      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");
      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");
      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");
      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");
      _list.Add("Hello");
      _list.Add("There");
      _list.Add("What do you think");

      int i = 0;
      foreach(string item in _list)
      {
        listView1.Items.Add(new ListViewItem(string.Format("{0}. {1}", i++, item)));
      }
    }

    private List<string> _list = new List<string>();
    private List<Timer> _timers = new List<Timer>();
    private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
    {
      // I'm going to add some code for the timer here.
      Timer timer = new Timer();
      timer.Interval = 1000;
      timer.Tag = e.Item;
      timer.Tick += new EventHandler(timer_Tick);
      timer.Start();
      _timers.Add(timer);
    }

    void timer_Tick(object sender, EventArgs e)
    {
      Timer timer = sender as Timer;
      if (timer != null)
      {
        timer.Stop();
        timer.Tick -= new EventHandler(timer_Tick);
        ListViewItem item = timer.Tag as ListViewItem;
        item.Remove();
        _timers.Remove(timer);
      }
    }
  }
}

Hi friends

for example here Main form(this is not maximized form) in which if i click button it will open new maximized form, after i doing the job i will close it.
problem is that after closing child form the parent MDI form is becoming maximized automatically.
can any one help to fix this problem

thanks

Thats by default. Do one thing, dont maximize the child form so as to prevent the parent MDI from maximizing.

child form has to be maximized, is there any other tech to handle ?

Uhm forgive me if I'm wrong, I have not worked with MDI for 15 years, but isn't an MDI main form a container for child forms and as such has to "contain" the child. Is it possible to drag a child form outside an MDI container these days. If this is the case then your question is a really dumb one.
