The second project

The second project is named SliderChangeEvent02 . This project was developed using the Flex 4 compiler and Flash Builder 4. This is ahybrid project that uses classes from both the Flex 3 (mx) library and the Flex 4 (spark) library. The behavior of this project is similar to the behavior of the other project, but they look different in several ways that I will explain later.

The third project

The third project is named SliderChangeEvent03 . This project is a modification of the hybrid project in which the classes used are drawnexclusively from the Flex 4 spark library.

Order of upcoming explanations

I will explain the Flex 3 project named SliderChangeEvent01 in detail. Then I will explain the differences between that project and the hybrid projectnamed SliderChangeEvent02 . Finally, I will explain the differences between that project and the project named SliderChangeEvent03 .

SliderChangeEvent01 output image at startup

The project named SliderChangeEvent01 starts running in Flash Player with the image shown in Figure 1 appearing in the browser.

The image that you see in Figure 1 consists of two Flex 3 Label controls, one Flex 3 HSlider control, and one Flex 3 Image control arranged vertically and centered in the browser window.

The Application container

All XML documents must have a root element. The root of a Flex 3 application is a container element that is oftencalled the Application container. (You can learn all about the Application container class at Adobe Flex 3.5 Language Reference .)

Briefly, the Application container, (which corresponds to the root element in the Flex XML code) , holds all other containers and components.

Vertical layout

By default, the Flex 3 Application container lays out all of its children vertically as shown in Figure 1. (As you will see later, this is not the case for the Flex 4 Application container.) The default vertical layout occurs when the layout attribute is not specified as is the case in this application. According to the Adobe Flex 3.5 Language Reference , the layout property:

"Specifies the layout mechanism used for this application. Applications can use "vertical", "horizontal", or "absolute" positioning.Vertical positioning lays out each child component vertically from the top of the application to the bottom in the specified order. Horizontal positioning lays out each child component horizontally from the left of the application tothe right in the specified order. Absolute positioning does no automatic layout and requires you to explicitly define the location of each childcomponent. The default value is vertical."

A toolTip on the slider

If you point to the slider with your mouse, a tool tip showing the word Height will appear as shown in Figure 2.

The slider's thumb

The little triangle that you see on the slider in these images is often referred to as the slider's thumb .

As you will see later, the position of the thumb is intended to represent the height of the image below the slider. The left end of the sliderrepresents a height of 100 pixels and the right end represents a height of 250 pixels (which just happens to be the actual height of the raw image) .

can someone help me with some logarithmic and exponential equations.

sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

silver nanoparticles could handle the job?

not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
