I have an 8x8 grid...On the grid i have a robot standing in the origin point (0,0)
Also,i have a little lamp placed at any tile RANDOMLY at the start of puzzle.
The robot can only move square by square either horizontally or vertically (no diagonals allowed!)
The robot wants to get to the lamp as quickly as possible (means in the least number of moves possible)
So how can i shorten the path?

The general answer to any pathfinding question is "have you checked out A*[^]?". So, have you? In the case of a uniform grid with no obstacles you can just go straight for the target, but I'm guessing this is a preliminary to pathfinding with obstacles, and in that case A* is exactly what you'll want.

How can I display 0 and 1 data in square wave form like in logic analyzer view in to datagridview controls or there is a special control for this kind of requirement?
|
|

The DGV isn't really into doing graphics like a logic analyzer. I think this would have to be a custom drawn control, like a Panel. That's WAY too much material to cover in a couple of forum posts.

Using any Control for individual bit samples is a horrible idea. What you need is one Control for the entire logic analyzer (or maybe one per channel), and within such Control paint all the time points yourself. I would use a Panel, and make extensive use of Graphics.DrawLine; there are only four cases to consider for previous and current sample:
- both 0: draw a horizontal line low;
- both 1: draw a hor line high;
- 0 becomes 1: draw a vertical line, then a hor line high;
- 1 becomes 0: draw a vertical line, then a hor line low.
And no, I don't have an example handy.
I do have an article[^] that gives the basics for graphics, and in essence it says store your data in some structures, then paint those structures inside the (On)Paint handler.

Thanks Luc Pattyn,
Graphics.DrawLine is a good start for me.
- both 0: draw a horizontal line low;
- both 1: draw a hor line high;
- 0 becomes 1: draw a vertical line, then a hor line high;
- 1 becomes 0: draw a vertical line, then a hor line low.
The user needs to manually construct/enter the wave form graphically one bit at a time and able to save and load the wave form.
Do you think I can draw line inside DGV cell?

I might be able to, but I don't plan on doing so as it makes no sense IMO. Forget DGV for this.

Do you mean, the contents of a single cell should contain a complete signal trace? Or do you have a data structure where cells contain single 1s and 0s?
In the former case, you need a custom control which you can put into a DGV (I think you have to inherit from DataGridViewCell but I forget exactly, it's a long time since I've done something like this). In the latter, you want a custom control which will draw the entire trace for you, you shouldn't be using a DGV at all in that case.

What have you tried thus far? Post your efforts, and we may be able to help fix what you've done. If you've done nothing, go elsewhere - Google works fairly well. We're happy to help with solving problems in your work, but we don't work for you.

and I want one of these[^] and $10,000,000 in my bank account.
The whole point is you have to work at getting this stuff. Nobody is going to just hand it to you. If you don't want to put the work into writing the code, why should we do it for you?

Anyone can help me in my problem on how to implement progress bar?..
for now i wanted to know how could implement a progress bar while executing threads like connecting to database, inserting, updating, deleting, retrieving data.. it's like generic that fits for all threads when every time i execute it..
someone could help me on this and can give me a sample better code in c#.net..
tnx a lot..

You cannot possibly have done any research on this subject at all, otherwise you would have stumbled across the many articles here on CP and the 1000s on the web with examples of this.
Send you the code! It is sitting out there waiting for you to do even the simplest search.

Using the BackgroundWorker, it is very easy to do. The main thing to be aware if that you should call ReportProgress at an appropriate rate to have a balance between progress bar updating and actual processing. As a starting point, you might report the progress each time the percentage is increased by 1.

i want to create a wind or rain effect in c#
|
|
|
|
|
In what? A still image? An XNA scene? DirectX? OpenGL? A small house just outside of Phnom Penh?

in still images like apply effect on picture box

It's obvious. Open Windows.

Yeah, but that's always such a pane!

You have two choices that I can see. One is to hand code the Paint routine to modify the image in a sequence that simulates rain falling, pixel-by-pixel. Or you can use a tool like photoshop to create a sequence of changed images, then save them in an animated .gif format. There may be other, better formats for animations than .gif, but I don't know of any that don't require a separate viewer. Try using Google to search for animation formats, and keep in mind that some will require that your user have some display tool installed to view some of them. Try to avoid that, if you can.
If that doesn't pan out, you can still go through the tedious task of sequencing hand-coded bitmaps using the Paint routine. Personally, I'd rather have a root canal, but tastes vary...
