Advanced Mouse Processing in Delphi Applications

You might already know how to handle some basic mouse events like MouseUp/MouseDown and MouseMove. However, there are times when you want your mouse to do what you tell it. Basic API stuff Many of us write programs that are designed to work only with the mouse. If we are writing programs that require mouse presence and/or are dependent on the mouse we have to be sure that various things are set up the right way. Is Mouse Present? The quickest way to see if the mouse is present: Animated Mouse Cursor Heres how to use animated cursors (or even how to use a BMP as a CUR): Positioning the Mouse The SetCursorPos API function moves the cursor to the specified screen coordinates. Since this function does not get a windows handle as a parameter, x/y have to be screen coordinates. Your component does use relative coordinates, e.g. relative to a TForm. You have to use the ClientToScreen function to calculate the proper screen coordinates. Simulations On most occasions we want the mouse to move to a certain position on the screen. We know that some components do not respond to a cursor change until the user moves the mouse, we have to provide some small move-from-code technique. And what about simulation mouse clicks without calling the OnClick event handler? The following example will simulate mouse click event on Button2 after the click to Button1. We have to use mouse_event() API call. The mouse_event function synthesizes mouse motion and button clicks. Mouse coordinates given are in Mickeys, where there are 65535 Mickeys to a screens width. Restrict The Mouse Movement Using the Windows API function ClipCursor, it is possible to restrict the movement of the mouse to a specific rectangular region on the screen: Mouse Enter, Mouse Leave? Detecting entering and exiting of the mouse pointer over a component is often coming up when writing your own component. All descendants of TComponent send a CM_MOUSEENTER and CM_MOUSELEAVE message when the mouse enters and leaves the bounds of the component. You will need to write a message handler for the respective messages if we wish to respond to them.

Irony in Pride and Prejudice Essay - 2389 Words

Pride and Prejudice is one of the most popular novels written by Jane Austen. This romantic novel, the story of which revolves around relationships and the difficulties of being in love, was not much of a success in Austens own time. However, it has grown in its importance to literary critics and readerships over the last hundred years. There are many facets to the story that make reading it not only amusing but also highly interesting. The reader can learn much about the upper-class society of this age, and also gets an insight to the authors opinion about this society. Austen presents the high-society of her time from an observational point of view, ironically describing human behavior. She describes what she sees and adds her own†¦show more content†¦She uses this unspecified person, who is outside of all the novels action and gives explanations, as a medium of communication to present her own opinion in an allusively open way. This narrator is the first means of making i ronic remarks. Through the narrator a certain mood is created that prevails throughout the novel. The very first sentence of the novel shows this with the following sentence, It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife (Pride and Prejudice, p. 3). The irony of this statement is the universal validity with which assumptions are made in that upper-class society. It is assumed that there is nothing else for a man of high rank to want but a wife to complete his possessions. Along with his money, land, riches etc. she acts as nothing more but another piece of property, which was a common attitude in those days. Austen manages to make the attitude towards matrimony upheld by this upper class look rather ridiculous and incredible. Another ironic description is given, for instance, when Miss Bingley and Mrs. Hurst take care of the sick Jane, who stays at their house. They present themselves as very affectionate and cari ng friends to Jane. However, that does not stop them from talking very bad about Janes relations.

September 4th 2012 RH 200 / Merar REACTION PAPER (JOURNAL) by Raymond Alvarez, Jr. I though the people profiled in  Without Pity: A Film About Abilities represented a fair cross-section of disabled individuals struggling against the world’s obstacles, to gain control of how they will eventually live. One story that really hit home with me was Charlie. We will write a custom essay sample on Without Pity or any similar topic only for you Order Now Being born with no legs and arms, Charlie showed great adaptation and intelligence and had such a go-getter attitude. He attends school with the help of a special wheelchair, and aside from his obvious disability, was very well accepted by everyone who got to know him. Charlie inspired me tremendously. His Mom and Dad are also very admirable in how they chose to let Charlie live a great life, and with so much determination to be a normal kid. I got teary eyed, not because of his disability, but because of his triumph in life. God has big plans for such a little guy. Charlie has a great message to deliver to this world. The other story, which I could most relate too was Josh. In his mid 20’s, a motorcycle accident paralyzed him. (I grew up riding motorcycles, and at any moment could have had a life changing accident. ) With obvious and understandable frustration, Josh shares the pains of being a quadriplegic. It took so much courage to share (on camera) the anger he suffers. He lost the love of his life amidst it all. The Victory was seeing him overcome to become, and eventually finishing his dream of college. I only pray to have that much courage to persevere if ever to face a life changing disability. I could only imagine it being much harder experiencing a major disability later in life as Josh did. Charlie never experience life with arms and legs, so in a graceful way, that may have made adjusting to his disability easier. Either way, they were a great testimony to (in my opinion) God’s loving grace, and the tremendous power of the holy (and human) spirit! What a great movie! How to cite Without Pity, Essay examples

Criminal Law Study Guide free essay sample

Murder carries a mandatory sentence of life imprisonment, which is 15 years. Sound memory—the person responsible must not be insane. Age of discretion — a child less than 10 years old is not criminally responsible for his/her actions. Since S. 34 of the Crime and Disorder Act of 1998 the presumption of doli incapax has been abolished and consequently any child over 10 years has potentially full legal capacity. Unlawfully kills — the act must be an unlawful killing. The law recognises that in certain circumstances the killing may be either justified or authorised eg. xecution or self defence. Living human being — a foetus is not deemed in law to be a living human being. However, a murder conviction may be possible if a foetus is injured and, after birth, dies as a result of injuries sustained whilst in the womb. Attorney-General’s Reference (No 3, 1994) 1996. A defendant cannot be convicted of the murder of someone who is already dead at the time of the attack. R v Maicherek and Steel 1981 The accused had seriously wounded the victim who was then artificially maintained on a respirator. When it was discovered that irreversible brain damage had occurred the respirator was turned off M was found guilty of murder and his appeal was dismissed when he claimed the doctor had caused death. It was his act which caused death. The court appeared to favour the approach that death occurs when the victim is brain-dead. Queen’s Peace — killing an enemy during wartime is not murder. Malice aforethought — since the case of R v Moloney the mens rea of murder is the intention to kill or cause grievous bodily harm. ACTUS REUS The actus reus of murder is that the killing is unlawful, causation must be stablished (A caused B’s death) and the victim must be a human being. (see causation notes from AS). MENS REA DIAGRAM MENS REA The mens rea of murder is malice aforethought which is the intention to kill or cause grievous bodily harm (GBH). There are two forms of intent: †¢ Direct intent — this is what D desires, eg. pointing a gun at someone and sh ooting them because you want to kill them. It was their aim or purpose to kill. †¢ Indirect or oblique intent — this is not necessarily what D desires but what he foresees will almost certainly happen, eg. D sets fire to a building and killed someone, did he foresee the risk that death might occur? Four important cases must be looked at. R v Moloney 1985 A soldier shot and killed his stepfather in response to a drunken challenge. He claimed that he had not aimed the gun at the victim and had, at the time, no idea that firing it would cause injury. The judge directed the jury that intention included both desire and foresight of probable consequences and the defendant was convicted of murder. Held (HL) Appeal allowed, manslaughter substituted. Lord Bridge did state that it was possible to intend a result which you do not actually want. He gave the example of a man who is trying to escape, who boards a plane to Manchester. Even though he may have no desire to go to Manchester — he may even hate the place — it is clearly where he intends to go. However, the appeal was allowed because foresight of consequences can only be evidence of intention — it is up to the jury to decide. R v Hancock and Shankland 1986 Two striking miners pushed concrete from a bridge onto a road, killing a taxi driver. They claimed only to intend to block the road or frighten the taxi passenger and not to kill or cause GBH. They were convicted of murder but successfully appealed, a manslaughter conviction was substituted by the Court of Appeal and confirmed by the House of Lords. The House of Lords looked at risk and probability. A slight risk of death is not enough to infer intention: Lord Scarman stated the greater the probability that death or GBH would occur; the more likely that intention can be inferred, eg. if A cut B’s little finger is would not be very probable that death would occur, therefore A is unlikely to have intention. However, if A stabbed B in the chest, it is much more likely that death would result, therefore it is more likely that A had intention. In both cases the defendants were convicted by the juries and appealed, first to the Court of Appeal and then to the House of Lords. In each case the House of Lords quashed the convictions for murder and substituted a verdict of manslaughter. The reason being the trial judges had misdirected the jury. The following case established the Virtual Certainty test which should always be used in indirect intention situations.. R v Nedrick 1986 The defendant set fire to a house, killing a child. He claimed that his intention was to frighten the child’s mother and not to kill or cause GBH. Convicted of murder. Held (CA) Appeal allowed, manslaughter substituted. Where direct intention is not present then the following test should be put to the jury. A jury should return a verdict of murder only where they find that the defendant foresaw death or serious injury as a virtual certain consequence of his or her voluntary actions. R v Woolin 1998 (HL) D shook his 3-month-old son when he choked on his food and then threw him across the room, the child died, D had lied to the ambulance men and the police before admitting what happened. He claimed that he did not want his son to die. He was originally convicted of murder but the House of Lords reduced his conviction to manslaughter. The trial judge had misdirected the jury on the test to infer intention. The case has now confirmed the Nedrick test. It must now always be used when dealing with indirect intent situations. R v Matthew and Alleyne 2003 (CA) The defendants appealed against their conviction for murder following the death of a young man (a non-swimmer) whom they had thrown from a bridge into a river. The Court of Appeal affirmed the conviction, which it did not consider unsafe in the light of the evidence, but expressed concern that the Nedrick/Woollin evidential rule should not be treated as if it were a rule of law. A defendant’s foresight of virtually certain death does not automatically require the jury to find that he intended that result: it is merely evidence from which the jury may draw that conclusion.
