Heres two hints...
1) Look at your Paint Method.
2) Decide where your Math.Rand should be.

I'm relatively new to scripting in JavaScript, so I'm not too surprised I'm having difficulty scripting up an animation effect for my personal site. What I'm trying to do is the following: When I go onMouseOver on a button in a nav bar, I want that button to switch to a different image while at the same time another blank image changes as an animation to an associated image. When I go onMouseOut, the bar image reverts back to the...

Setting backcolor for the animation control does not take effect. The BackStyle property is set to cc2BackstyleTransparent. No matter what BackColor property is set to, in run time the backcolor is always SystemColors.Control.

Hello, I'm new to c# and have created an animation which draws directly to the window, it uses the code below which all works. I would like to know if this is the 'correct' way to do it - or would an experienced c# programmer do it another way? This part defines the screen and the graphics pad I'm drawing to: Graphics screen = CreateGraphics(); Graphics drawpadg = Graphics.FromImage(drawpad);

My application has a lot of complicated SQL statements, calculations, processing that takes time. I've created a custom form to act like a messagebox. It has 10 small rectangles on it that change color sequentially to let the user know that processing is occurring. This 'animation' occurs via the form timer event. However, I'm having trouble getting the animation to occur for all types of processing events. It appears that I have to...

This is a project I have been working on lately and I keep running into problems. The idea is to be able to attaching an animation to a movie clip and call it later. Or multiple animation at once. example: on the stage you have a black box called: myClip in actionscript you type: growClip = grow(myClip); spinClip = spin(myClip); now when you call:

Most applications, including Windows Explorer, show some sort of 'wait' dialog with animation when a lengthy operation is going on. For example, When the Windows Explorer is searching for something, it shows a small dialog with a moving flashlight. I examined the explorer.exe and found that that was an avi file. Now that, I would like to do similar thing in my C# application. But what is the most efficient way to do so? 1)Manually...

As part of familiarizing myself with the Win32 API, I wrote a simple animation program in C. The program has a struct for each bitmap, holding information such as its location, visibility, mask (for transparency), etc. Then I have a separate thread running that has a WHILE loop that looks like this: WHILE (TRUE) { /* update all structs (bitmap locations, etc) */ SleepEx(iSpeed, FALSE); InvalidateRect(hwnd, lpRect, TRUE); }

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
