Click and Drag a Delphi Form Without the Caption Bar

Click and Drag a Delphi Form Without the Caption Bar The most common way to move a window is to drag it by its title bar. Read on to find out how you can provide dragging capabilities for Delphi forms without a title bar, so the user can move a form by clicking anywhere on the client area. For example, consider the case of a Windows application that doesnt have a title bar, how can we move such a window?  In fact, its possible to create windows with a nonstandard title bar and even non-rectangular forms. In this case, how could Windows know where the borders and the corners of the window are? The WM_NCHitTest Windows Message The Windows operating system is heavily based on handling messages. For example, when you click on a window or a control, Windows sends it a wm_LButtonDown message, with additional information about where the mouse cursor is and which control keys are currently pressed. Sounds familiar? Yes, this is nothing more than an OnMouseDown event in Delphi. Similarly, Windows sends a wm_NCHitTest message whenever a mouse event occurs, that is, when the cursor moves, or when a mouse button is pressed or released. Code to Input If we can make Windows think that the user is dragging (has clicked on) the title bar rather than the client area, then the user could drag the window by clicking in the client area. The easiest way to do this is to fool Windows into thinking that youre actually clicking on the title bar of a form. Heres what you have to do: 1. Insert the following line into your forms Private declarations section (message handling procedure declaration): procedure WMNCHitTest(var Msg: TWMNCHitTest) ; message WM_NCHitTest; 2. Add the following code into the implementation section of your forms unit (where Form1 is the  assumed form name): procedure TForm1.WMNCHitTest(var Msg: TWMNCHitTest) ;begin   Ã‚   inherited;  Ã‚   if Msg.Result htClient then Msg.Result : htCaption;end; The first line of code in the message handler calls the inherited method to obtain the default handling for the wm_NCHitTest message. The If part in the procedure intercepts and changes your windows behavior. This is what actually happens: when the operating system sends a wm_NCHitTest message to the window, together with the mouse coordinates, the window returns a code that states which portion of itself has been hit. The important piece of information, for our task, is in the value of the Msg.Result field. At this point, we have an opportunity to modify the message result. This is what we do: if the user has clicked in the forms client area we make Windows to think the user clicked on the title bar. In Object Pascal words: if the message return value is HTCLIENT, we simply change it to HTCAPTION. No More Mouse Events By changing the default behavior of our forms we remove the ability of Windows to notify you when the mouse is over the client area. One side effect of this trick is that your form will no longer generate events for mouse messages. Captionless-Borderless Window If you want a captionless borderless window similar to a floating toolbar, set the Forms Caption to an empty string, disable all of the BorderIcons, and set the BorderStyle to bsNone. A form can be changed in various ways by applying custom code in the CreateParams method. More WM_NCHitTest Tricks If you look more carefully at the wm_NCHitTest message youll see that return value of the function indicates the position of the cursor hot spot. This enables us to play some more with the message to create strange results. The following code fragment will prevent users to close your forms by clicking on the Close button. if Msg.Result htClose then Msg.Result : htNowhere; If the user is trying to move the form by clicking on the caption bar and dragging, the code replaces the result of the message with a result which indicates the user clicked on the client area. This prevents the user from moving the window with the mouse (opposite to what we were doing in the begging of the article). if Msg.Result htCaption then Msg.Result : htClient; Having Components On a Form In most cases, well have some components on a form. Lets say, for example, that one Panel object is on a form. If Align property of a panel is set to alClient, the Panel fills the entire client area so that it is impossible to select the parent form by clicking on it. The code above will not work - why? Its because the mouse is always moving over the Panel component, not the form. To move our form by dragging a panel on the form we have to add few lines of code in the OnMouseDown event procedure for the Panel component: procedure TForm1.Panel1MouseDown  Ã‚   (Sender: TObject; Button: TMouseButton;  Ã‚   Shift: TShiftState; X, Y: Integer) ;begin   Ã‚   ReleaseCapture;   Ã‚   SendMessage(Form1.Handle, WM_SYSCOMMAND, 61458, 0) ; end; Note: This code will not work with non-window controls such as TLabel components.

History and Impact of Computing - Essay Example Its formation was intrigued by the demand for work force by the 100th battalion war department. Recruitment of the military personnel involved both Americans and Japanese volunteers. Though 2100 Japanese were recruited, they felt that the unit that was created was a strategy by the white military to protect themselves. In addition, their reluctance to join the army was because the elegance forms required the Japanese to denounce their nationality. In regards to this, most Japanese youth felt that it was an insult to their emperor (Black, 2001). The Caucasians held the official position in the regiments. The group participated in several wars such as the wars at Luciana, Belvedere, and Livorno. The casualty percentage of Japanese-American units was rated at 314 percent. Recognition for the lost lives of the volunteers was made through awards for their courage and bravery in the battlefields. Just like the African-Americans dedication in the Second World War, President Truman honored t he Japanese-Americans for their devotion to wars in Italy and Southern France. The Armed Forces was desegregated in order to allow equality and fare enrolment. The success of the war was ascribed to role the Japanese Americans played. More importantly was the war against Japan where they acted as translators and interpreters. Their service in the Military Intelligence Service was manifested in their ability to capture Japanese secret communication thus making orders to Japanese officers and quick elucidations of their enemies’ military communication code. Their involvement was significantly felt at Saipan and Okinawa. They calmed down terrified civilians due to the terror threats that were propagated by their Japanese government. They also convinced some Japanese soldiers until they surrendered (Black, 2001). Despite the 442nd impeccable service that earned the rest of Japanese-soldiers respect, the West Coast perceptions of these soldiers were different from that accorded to the Americans soldiers. Though the 442nd regiment survivors had earned the country victory in the wars, they were reunited with their families who had been placed in isolation camps. Similarly, the Japanese war veterans were harshly treated in their homes. Their residents were constantly set a blaze or vandalized and most restaurants and local shops dined offering their services to them. Though some soldiers were disbanded from wars during Italy’s post-war occupation duty due to their Japanese ancestry, President Harry Truman honored their efforts by pinning the seventh Presidential Unit Citation on the 442nd unit’s color. The reactivation of 442nd regiment unit in Hawaii following its inactivation in Honolulu proved the unit as an organized reserve unit. The recent recognition of the Asian Pacific Americans veterans of the U.S Army Second World War was held on 21 day of June in 2000. The move was an effort towards correction of the racial prejudice that had character ized United States during WWII. In regards to this recognition, the 442nd Japanese infantry earned twenty-one medals. The American Navajo Code Talkers During World War II, which started from 1939 to1945, approximately 50,000 New Mexicans were involved in almost every assault the United States marine forces raged on areas such as Peleju, Tarawa, Iwo Jima, and Guadalcanal in the

Film studies (Authorship module) Essay Example | Topics and Well Written Essays - 1500 words

Film studies (Authorship module) - Essay Example Today, no contemporary American director more deserves the title of auteur than Martin Scorsese Martin Scorsese is the perfect example of an auteur because he uses the same thematic consistencies throughout all of his work. These entail Catholicism, virgin/whore conflict, redemption, ethnic pride, and of course crime culture. On top of this, he supports all of his plots with very eclectic soundtracks. The cinematography he uses is very similar in all of his films. He utilizes the fluid motion of the camera with each shot, while making the mis-en-scene of each frame valuable to the plot of the story. He is also know for using some of the same actors in his films, specifically Robert Deniro, Joe Pesci, and Harvey Keitel. Of his large body of work, Mean Street symbolizes the blue print to the archetype that has become his unique style. Scorsese has a visual style that relies on the city of New York. Mean Street embodies the culture that comes with this location. In the film, the audience is subjected to getting to know characters who spend their time womanizing, hustling, fighting, and drinking. Centered on the struggles of four men in their mid-20's and all residents of Little Italy, who are working their way up the rungs of gangster culture, some are loan sharks, and some are just plain hoods. Tony (David Proval) is a big friendly guy who runs the neighborhood bar; Michael (Richard Romanus) is a small-time loan shark who tends to rip off Brooklyn adolescents. Johnny Boy (Robert De Niro) is an irresponsible hood who borrows money from loan sharks that he never intends to pay back, and Charlie (Harvey Keitel) is the nephew of the mafia boss Giovani (Cesar Danova). Charlie's only aspiration is to run his own restaurant. Mean Street is authentically based on specific events Scorsese saw almost regularly while he was brought up in Little Italy. The screenplay for the film initially started out as a continuation of Who's That Knocking. Scorsese changed the title from Season of the Witch to Mean Street. The film is arguably Scorsese's most religious film, even more so than his film The Last Temptation of Christ. This is in part due to the fact that the original draft of Mean Street centered on the religious conflict inside of Charlie and how it was affecting his world view. Charlie sees saving Johnny Boy as a way to find redemption. His aspirations for sainthood are played out through his behavior on the streets, as opposed to going to church. This is one of the implied meanings in the film. The implied meaning that comes with an auteur directed film is all present in Mean Street. In his article Senses of Cinema, Marc Raymond points out many of the film's intricacies. He argues that there is an implied homoeroticism between Johnny Boy and Charlie. He points this out when he says: The couple of the film is clearly Charlie (Harvey Keitel) and Johnny Boy (Robert De Niro) rather than Charlie and his girlfriend Theresa (Amy Robinson). This can be seen in one particular sequence in which Charlie and Johnny Boy stay out all night and sleep in the same bed together. Charlie gets out of bed and goes to the window, where he sees Theresa dressing. The next scene cuts to Charlie and Theresa making love in a hotel room. (Raymond, Pg1) Raymond argues that Johnny boy plays the part of the Femme Fatale and that this is a very

John Steinbecks East of Eden - Biblical Symbols and Symbolism Essay e

Biblical Symbolism in East of Eden    Throughout the novel East of Eden, Steinbeck uses many biblical references to illustrate clearly the conflict between the opposing forces of good and evil. Much of the plot of East of Eden is centered upon the two sets of brothers representing Cain and Abel.   Both pairs are similar to Cain and Abel in the way they go about winning their fathers’ favors.   All four give gifts to their fathers, and the fathers dismiss the gifts of Charles and Caleb, the Cain representations (Marks, Jay Lester. p.121).   Caleb and Charles Trask are obviously the more malignant brothers.   They are also the more loving towards their father.   Steinbeck’s purpose in this is to illustrate the need of the Cain character in the story.   Abel, Adam and Aron, is the opposite of his brother and naturally good and pure.   The purpose of Adam and Aron in East of Eden is to clarify the belief that purity must know wickedness (Marks, Jay Lester. p.122).   Steinbeck illustrates the nee d for both good and bad with the actions and beliefs of these supposed â€Å"good† characters.   The representations of Abel, Adam and Aron are both described as unloving.   Adam has not treated his children fairly and his treatment is caused by his innate goodness.   Aron grows as an ignorant selfish person because he is naturally good (Fonterose, Joseph.   p. 3382).  Ã‚   Steinbeck uses Cain to illustrate the choice man has.   In the case of Charles, Cain dies an unhappy man who did not live a worthwhile life, Caleb on the other hand, chose to realize his dark past, but chose to continue living his life with hope (Marks, Jay Lester.   p. 122-123).     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In Steinbeck’s East of Eden he is constantly using single characters to illustrate many differen... ....   Because of man’s evil heritage, being descendent of Cain, he is naturally forgiven for any breach in purity (Levant, Howard. p. 244).     Ã‚  Ã‚  Ã‚  Ã‚   Steinbeck’s references and allusions to the bible are very obvious.   Although they are most apparent when taking the story of Genesis: 4 into consideration, the more subtle devices are equally as useful to Steinbeck to prove his point.   His beliefs of the relationship between good and evil are easily understood with the allusions that are exercised.   Works Cited Fontenrose, Joseph.

Company: Bembos

Peru has several fast food chains that compete with the North American fast food chains like McDonalds and Burger king. One of the best local competitors is Bembos. Bembos sells burgers, fries, chicken sandwiches, the usual fast food, but with plenty of Peruvian flavor and style. Bembos is the company that I chose because it’s a successful business. It’s the leader of all the Peruvian fast food restaurants nationwide. Bembos has its unique twist that combines American flavor with our cuisine. The purpose of this essay is to show the theoretical model, facts analysis and the proposed decisions for the company. If we start with Bembos’ history, Bembos was established in 1988, with its first restaurant opening in the Miraflores district of Lima. Bembos mixes in spices with their meat, giving the patty a distinct taste and appearance. For example, their hamburger called â€Å"Bembos a lo pobre† includes a fried egg and fried plantain with the lettuce and tomato. The â€Å"Bembos Parrillera† is a burger topped with chorizo. Bembos meals primarily come with French fries or yuquitas (made from yuca root). As their website states, they can be found all over the Lima area. They also deliver orders to private houses. On the other hand, Bembos has 30 restaurants in 6 cities, mostly in Lima. In July 2007, it had opened a restaurant in the center of Cusco, becoming the first national or international fast food establishment in the city. Bembos has recently opened restaurants outside of Peru, located in India and Panama. Bembos’ prosperity allows it to ask for loans and be able to afford them. As I mentioned before they took this advantage and made an investment of expanding its growth in the international market. Bembos’ marketing plan relies on the fact of being always the number one, having propagandas and commercials on TV all over Peru. Their theoretical model relies on its 4p’s, which means: price, place, promotion and product. They focus on having a good location, in a nice and commercial area that can attract people. Bembos places are big and colorful and have a parking lot. They are easy to recognize because of its colors and style. When it comes to quality, they try to offer, in this case, bigger hamburgers with better quality but with a slight more expensive price than McDonalds, KFC, and Burger King. The strategy they use is by satisfying their costumers’ needs, by having good prices for their big hamburgers and asking for their preference. Bembos is always trying to get better as time goes by. They never get stuck into the same product; they continue renovating their products and offers. They have in mind that people will eventually get bored of having the same products, in this case, each year they come up with a different kind of hamburger, salad or ice cream. Moreover, they also have a good relationship with people that have power in the government, in order to avoid problems with them. Moreover, Bembos has never had any issues with the environmental people because of polluting the environment and animal cruelty. It’s always very important to take into account, that Bembos should even be considered not only a fast food restaurant, but a restaurant in general, since they just don’t offer hamburgers or ice cream, but they also offer â€Å"salads†. Therefore, that makes them approach for a bigger market, in case someone’s on a diet, they can eat in Bembos too. When it comes to the human resources and financial area. So far, they’ve done such a great job, since it’s never been reported that they’ve had any kind of trouble in those areas. Bembos employees are friendly and they offer to the customer a good service. They are trying to make customers happy when they come to Bembos. In conclusion, the main keys of success for Bembos are: high profits, good quality and service, wise marketing strategy, and good relationships. Also, they’ve always had a clean reputation, since they’ve never been issued with any person, like getting intoxicated and the like, which makes them have a great image for their costumers. Plus, they have a great staff, the workers are very nice people who make the costumers want to come back, which’s essential, since if we offer a good service, people will want to come back, and it’ll eventually create more sales, which’s essential for all kinds of businesses.

Juvenile Prison Is the Best Way of Reforming Essay

The Juvenile System has been around for a long time. The primary reason behind separating Juvenile from adult criminals is quite simple; the judicial system believes that the children are less culpable for their irresponsive behavior and they could easily be reformed as compared to adult offenders. The crucial role of the judicial system is to critically investigate, diagnose, and recommend treatments for the Juveniles rather than accrediting them. However, because of the increasing number of juvenile arrest for crimes committed by persons considered as a child, the attention that the given to a crime involving juveniles, the decreasing trust to the juvenile system itself and the lauder roar of the society for a safer place to live in,†¦show more content†¦For example, in 1996 the legislature in the state of Missouri lowered the minimum age for transfer from fourteen to twelve (Zierdt, 1999, p.419). States in favor of this kind of shift justify the transfer because chronic juvenile offenders in rehabilitation centers will likely disrupt the reformation of other juvenile offenders as they are considered as a bad influence on them. It is thus, considered that in not transferring the juveniles in adult prisons, these chronic juvenile offenders disrupts the growth and development of other teens undergoing rehabilitation. On the other hand, the advocates of the juvenile system believe that because children are not fully mentally or physically developed, they are not therefore accountable for their actions in the same way as adults (Ainsworth, 1995, p.932-933). Juvenile criminality for them is â€Å"youthful illness† brought about by external forces like environment or impoverished living conditions. Donna Bishop, an advocate of the juvenile justice system, encourages states to give these juveniles â€Å"room to reform.† She believes that a policy that is designed to discard youth in the middle of the transition to adulthood is uncharacteristic of a fair government (Bishop, 2000, p. 159).
