I have a class that inherits NativWindow, I would like the same class to also implement IDisposable.
The problem is that C# wont let me inherit NativWindow and IDisposable (multiple inheratence).
So, is it posible?
Or is there some reason why I should not even be trying to do this?
Thanks.

No, it doesn't. You're allowed to inherit from one base class, and you can implement multiple interfaces. If you wrapped your IDisposable in a class, then you should read up on creating a composition.
Good luck.

BindingNavigator save button does not save info to table.
Detail for two tables dragged into a form. Using BindingNavigator add a new record, Enter data in the form. Using save button in navigator Saves the data for main table but not the one connected by foreign key.

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.

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?

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.
