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

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.

InitializeComponent();
listView1.SmallImageList = AlertImageList;
m_Timer = new Timer();
m_Timer.Interval = 5000;
m_Timer.Tick += new EventHandler(m_Timer_Tick);

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.

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.

Hi, In my database table i have column with data like
00987
78960
89760
08123
009876
when i read the value(00987) into the integer variable, then it contiana value as 987.
I need the value in integer variable as same(00987). How can i do this?
int k = Convert.ToInt16(dt.rows[i]["colname]);

00987 is the same as 987. If you read it into an integer variable, then it will remove leading zeros. If you want to display it as it is in the database, then convert it to a string instead of an integer
