A Guide to Using the TClientDataSet in Delphi Applications

Looking for a single-file, single-user database for your next Delphi application? Need to store some application specific data but dont want to use  the Registry / INI / or something else? Delphi offers a native solution: The TClientDataSet component -- located on the Data Access tab of the component palette -- represents an in-memory database-independent dataset. Whether you use client datasets for file-based data, caching updates, data from an external provider (such as working with an XML document or in a multi-tiered application), or a combination of these approaches in a briefcase model application, take advantage of the  broad range of features that client datasets support. Delphi Datasets A ClientDataSet in Every Database ApplicationLearn the basic behavior of the ClientDataSet, and encounter an argument for the extensive use of ClientDataSets in most database applications. Defining a ClientDataSets Structure Using FieldDefsWhen creating a ClientDataSets memory store on-the-fly, you must explicitly define the structure of your table. This article shows you how to do it at both runtime and design-time using FieldDefs. Defining a ClientDataSets Structure Using TFieldsThis article demonstrates how to define a ClientDataSets structure at both design-time and runtime using TFields. Methods to create virtual and nested dataset fields are also demonstrated. Understanding ClientDataSet IndexesA ClientDataSet does not obtain its indexes from the data it loads. Indexes, if you want them, must be explicitly defined. This article shows you how to do this at design-time or runtime. Navigating and Editing a ClientDataSetYou navigate and edit a ClientDataSet in a manner similar to how you navigate and edit almost any  other dataset. This article provides an introductory look at basic ClientDataSet navigation and editing. Searching a ClientDataSetClientDataSets provide several different mechanisms for searching for data in its columns. These techniques are covered in this continuation of the discussion of basic ClientDataSet manipulation. Filtering ClientDataSetsWhen applied to a dataset, a filter limits the records that are accessible. This article explores the ins-and-outs of filtering ClientDataSets. ClientDataSet Aggregates and GroupStateThis article describes how to use aggregates to calculate simple statistics, as well as how to use group state to improve your user interfaces. Nesting DataSets in ClientDataSetsA nested dataset is a dataset within a dataset. By nesting one dataset inside another, you can reduce your overall storage needs, increase the efficiency of network communications and simplify data operations. Cloning ClientDatSet CursorsWhen you clone a ClientDataSets cursor, you create not only an additional pointer to a shared memory store but also an independent view of the data. This article shows you how to use this important capability Deploying Applications that use ClientDataSetsIf you use one or more ClientDataSets you may need to deploy one or more libraries, in addition to your applications executable. This article describes when and how to deploy them. Creative Solutions Using ClientDataSetsClientDataSets can be used for much more than displaying rows and columns from a database. See how they solve application problems including selecting options to process, displaying progress messages and creating audit trails for data changes.

Christian Science Child Care free essay sample

Examines conflict between freedom of religion (churchs refusal of medical care for children) laws against child abuse/neglect. Child abuse has engendered a set of case law that is intended to protect children from both abuse and neglect by their parents. These laws sometimes interfere with another legally protected activity, the free exercise of religion. Several legal cases in recent years have tested the limits of religious expression with reference to children, notably cases in which parents who do not believe in medicine have prevented their children from receiving medical treatment for religious reasons. The issue has become enmeshed with what might be called the larger parental rights movement which holds that all decisions regarding the welfare of children should be made by parents and not by government or the courts. What has developed in these cases is a conflict between the desire on the part of society to assert childrens rights and to protect children and the belief.

The Two Gentlemen of Verona Essay Example

The Two Gentlemen of Verona Essay Darko Karamatic Class: Humanities Professor: Michael Martin Date: November 1, 2009 The Two Gentlemen of Verona The Two Gentlemen of Verona by Shakespeare is a huge art, and Shakespeare as the man that invented its own language of writing is definitely one of the best artists ever. In The Two Gentlemen of Verona which in one sense seems to be unreal story in another is very real. The relationship between best friends as in this section is reduced to such a cynical attitude as it is between Proteus and Valentine. The Two Gentlemen of Verona Proteus and Valentine, known as best friends and their infatuation to the same woman named Silva has led them into trouble. Proteus, a character who in my opinion is a hypocrite and false friend was also able to betray his best friend, Julia and everyone in his vicinity. When Valentine was supposed to go to Milan he also called his best friend Proteus to come with him, but he refused to go. He refused his best friend because of the love he felt towards Julia, but in the meantime his father was persuaded him to leave Verona and go to Milan to gain some life experience.

Since Proteus had to leave Verona in a sign of eternal fidelity he exchanged rings with Silvia. After his arrival in Milan Proteus soon forget on Julia and fall in love with the love of his best friends Silvia. As to his best friend, Valentine was not hiding anything from Proteus, and he was not expecting his cunning and jealousy. He told to Proteus all about his visiting Silvia and the love they felt between each other. He also told him about her father, the Duke of Milan, and that he wants her to marry wealthy guy, in this case Thurio. Silvia and Valentine were in love until nasty Proteus did not decide to do anything in his power just to get Silvia’s love. Proteus has decided to go and tell everything to Silvia’s father, all about the relationship between Valentine and Silvia and their plans to escape Milan together. When Duke heard all this stuff he was very surprised because he thought they were just friends. Proteus also asked Duke ot to tell anyone how he found out about this, because Valentine was his best friend.. The Duke immediately wanted to remove Valentine away from his daughter and he did it, he banished Valentine from Milan. In the meantime, Proteus was faking that he wanted to help Thurio to win Silva’s love. In conversation with Proteus, Thurio was persuaded to pay musicians and play serenade under Silvia’s window. After Thurio finally decided to do so, b efore the musicians started playing, Proteus told him to hide and leave him alone in order to help him to win Silvia. Of course it was just a trick for poor Thurio, because Proteus’ intent was to make Silvia think how he prepared all this show for her. At the same time Julia has decided to go to Milan and look for her love Proteus. After her arrival to Milan she found out that Proteus was already in love with another woman and was very disappointed. Since she did not know what to do she decides to disguise as a man and soon after she became his page, called Sebastian. In one situation Proteus sends Sebastian to deliver a letter to Silvia and with the letter he also sends her a ring (the same one which he got from Julia as a sign of great love). After valentine was banished from Milan, he was attacked by outlaws. Instead of just robbing him they started talking and Valentine lied how he was banished from the city because he killed a man. The outlaws told Valentine how they were gentlemen too but they were banished and now they live in the forest. Besides that, they told Valentine that he must become their leader or they will have to kill him. Since Valentine did not have another choice valentine agreed and became one of them, actually more than that, he became their leader. As every comedy has happy end this one was the same way. After Silvia decided to go to the city she was comforted by the outlaws who took her to their leader Valentine. Although I really do not like Proteus as a person, Jeff Bukovinsky had fantastic play. His expression of emotions was just amazing. For instance, when he managed to deceive his best friend, Valentine, as well as the Duke. Furthermore, his falling in love practically every five minutes is just unreal and silly, but he still shows it with so many great importances as it is the very last one. The Proteus as a person is just a garbage, nasty character and it is not worthy anything but the actually acting by Bukovinsky was performed just excellent and deserves all the credit. In addition, the part which I (with not big knowledge) consider as the best played by Bukovinsky was one where Silvia and Proteus were in the forest. There, after refusing his love Proteus having no other choice threatened to rape Silvia (â€Å"Ill force thee yield to my desire†). At the very beginning of the play the audience seemed very excited and tried not to miss anything, and the excitement increased as the show went on. In the second part of the play everyone was paying sharp attention, especially at the moment when Duke found out about Silvia’s and Valentine’s hidden love. Everyone seemed itchy and was waiting for the end even though most of them knew what was going to happen, they were eager to see the scene. The most emotional scene in audience was when the Duke approved love between his daughter and Valentine. I personally think that the play left much more impressions and was much more interesting than actual reading to me. At the play I felt like I was so into it, and could not move my eyes from the stage. At some point, I understood everything that was going on which was not true in case while I was reading the book. Hence, all the credit from me goes to the actual play. Arrangement of characters on stage and just carrying out the performance was fantastic and at the same time professional. I did not notice any single mistake by the actors, and every step they were taking seemed like taken with a big confidence, like they were doing it forever.
