Append Formatted Lines Using SelText and SelStart

The TRichEdit Delphi control is a wrapper for a Windows rich text edit control. You can use a Rich Edit control to display and edit RTF files. While you can create nice user interface around the Rich Edit control with toolbar buttons to set and change text display attributes, adding formatted lines to Rich Edit programmatically is fairly cumbersome - as you will see. How to Add Formatted Lines to Rich Edit To create bold text from a selection of text displayed in the Rich Edit control, at runtime, you need to make a section of text and then set the selections properties to SelAttributes. However, what if youre not dealing with a selection of text and instead want to add (append) formatted text to a Rich Edit control? You might think Lines property can be used to add bold or colored text to Rich Edit. However, Lines is a simple TStrings and will accept only plain, unformatted text. Dont give up - of course, theres a solution. Look at this example for some help: //richEdit1 of type TRichEdit with richEdit1 do begin //move caret to end SelStart : GetTextLen; //add one unformatted line SelText : This is the first line #13#10; //add some normal font text SelText : Formatted lines in RichEdit #13#10; //bigger text SelAttributes.Size : 13; //add bold red SelAttributes.Style : [fsBold]; SelAttributes.Color : clRed; SelText : About; //only bold SelAttributes.Color : clWindowText; SelText : Delphi ; //add italic blue SelAttributes.Style : [fsItalic]; SelAttributes.Color : clBlue; SelText : Programming; //new line SelText : #13#10; //add normal again SelAttributes.Size : 8; SelAttributes.Color : clGreen; SelText : think of AddFormattedLine custom procedure...; end; To start, move the caret to the end of the text in the Rich Edit. Then, apply formatting before you actually append the new text.

Essay on Kurt Vonnegut’s Harrison Bergeron A Picture of...

Illustration of false equality The year was 2081, and everybody was finally equal (208). This in a nutshell is the premise of Kurt Vonnegut’s short story Harrison Bergeron. Vonnegut’s title character Harrison Bergeron is a picture perfect human being: very tall, handsome and intelligent. Although our society would deem these desirable attributes, in this story’s 2081 AD setting they are highly objectionable. Kurt Vonnegut uses the character Harrison Bergeron to illustrate the danger of imposing total equality on a diversified population. In Bergeron’s society uniformity is strictly imposed upon all citizens. Physical adjustments are levied to achieve this uniformity: tall people wear weights, disturbing sounds administered†¦show more content†¦His spectacles cause him to be half-blind and give him whanging headaches (211). In order to offset his looks the Handicap Generals require that he wear a red rubber ball for his nose, shave his eyebrows and cap his white teeth in black. In Harrison, Vonnegut has obviously created an exceptional human being. When Harrison decides to escape his bonds he is considered an enormous threat. The television station interrupts its normal broadcasts to warn the populous of him, describing him as a genius and an athlete†¦extremely dangerous (210). Breaking into the broadcast studio he appears Clanking, clownish and huge, Harrison stood in the center of the studio. The knob of the uprooted studio door was still in his hand (211). Harrison realizes his power, proclaiming Even as I stand here- crippled, hobbled, sickened-I am a greater ruler than any man who ever lived! Now watch me become what I can become†¦ (211). His proclamation reveals the maturity of a fourteen-year-old, but indicates his realization of his potential. Harrison issues the invitation to the first woman who dares rise to her fee claim her mate and her throne (211). A ballerina who has the courage to join him, reveals with the removal of her restraints she is blindingly beautiful (212).

Astronomy Photographic Process

Question: Describe about Astronomy? Answer: The collodion process is one of the earliest photographic process, invented by Frederick Scott Archer that replaced the glass photographic plates. These plates were able to record microscopically fine details that could be used for specified purposes and these plates lived for a long time till the discovery of the gelatin dry plate. These were later used in the printing industry and for other larger work that was cheaper than gelatin films. The universal tree of life depicts the planned evolutionary relationships in all the cellular life forms, that has been categorized under three primary heads or urkingdoms. These are the Archaea (archaebacteria), Bacteria (eubacteria) and Eucarya (eukaryotes) (Forterre Philippe, 1999). This universal tree of life has raised a number of vital questions on life. However, the whole genome deoxyribonucleic acid (DNA) sequences from the species of the three domains had given rich data to reconstruct the universal tree. The presently accepted Universal tree of life is supported by the molecular phylogenies. Particularly, the early genome evolution has assisted in shaping the extensive occurrence of the horizontal or lateral gene transfer between the species from variety of domains that are remotely related. In the 1970s it was Carl Woese who proposed the variety in the sequencing of the DNA encoded ribosomal RNA in organisms that would provide vital information regarding the evolutionary process of life (Forterre Philippe, 1999). Stromatolites are bio-chemical accretionary structures which are layered and are formed in shallow water when sedimentary grains by biofilms of microorganisms, such as cyanobacteriaare trapped or bound or cemented (Sanderson, 2008). These structures give the oldest records of life on Earth through fossil remains that exist for almost 3.5 billion years ago. Scientific institutes such as California Institute of Technology and Jet Propulsion Laboratory (JPL) have given proof that some of the extremely old stromatolites on earth were made by the help of those ancient microorganisms that are also extinct and this research helped to understand the earliest record of life in our planet (Sanderson, 2008). Geologists state that most of the young stromatolites that are present now are of biological origin and are nearly billion years old. These stromatolites are formed with the layer of microbes that generally grows in thin film on seafloor. The Great Oxygenation Event is also known as the Oxygen Crisis or the Oxygen Catastrophe or the Oxygen Revolution (Kerr, 2009). This was the period when DiOxygen was introduced in the Earths atmosphere. The evidence based on the chemical, geological and isotopic analysis state that a huge environmental change took place 2.3 billion years ago. Cyanobacteria, an organism that appeared two hundred years ago before the GOE had begun producing free Oxygen by the process of Photosynthesis. Before the GOE, free Oxygen was produced chemically through dissolved iron. When these Oxygen sinks became saturated and was not able to capture all the Oxygen the Great Oxygenation Event occurred and after this event the free Oxygen accumulated in the atmosphere (Kerr, 2009). This free Oxygen was toxic for the anaerobic organisms and when the concentration of Oxygen increased in the atmosphere and lead to the extinction of the anaerobic organisms. Moreover, this free Oxygen reacted with other gases such as methane, which reduced its concentration and led to the Huronian glaciations. Saturns largest moon is called Titan and in the entire solar system it is the second largest moon. It is the only moon that is surrounded with clouds and exhibits a thick atmosphere similar to planets (Perrot Giordani, 1998). The moon is surrounded by an orange haze which makes the mystery surrounding the satellite more dense. The mystery was solved by the Cassini/Huygens mission. The atmosphere of this satellite is complicated but active and is primarily made up of nitrogen (95 percent) and methane (5 percent). Scientists claim that these conditions are same as that of Earth during the early years of the planet. The only difference being that being closer to sun earth was comparatively warm (Mitchell, 2008). During the missions of the Cassini it came up with the basic data of the structure and organic chemistry of the atmosphere. Cassini also discovered enough materials that have compelled the scientists to suspect the presence of ocean in the planet that may be composed of water and ammonia.

Worlds Fair Crystal Palace Essay Example For Students

Worlds Fair Crystal Palace Essay During the 1800s Great Britains empire stretched around the world, and with raw materials easily available to them this way, they inevitably began refining and manufacturing all stages of many new machines and other goods, distributing locally and globally. However, despite being the central workshop of the world, Britain was not producing the highest quality of merchandise. When comparing factory-made products made in England to surrounding countries, most notably France, those products could not compare as far as craftsmanship and sometimes, simply innovation. It was suggested by Cole and supported by Prince Albert that England host a sort of free-for-all technological exposition to bring in outside crafts into the country. These planners supported free trade, thinking that if local business was exposed to foreign-made goods, they could incorporate those new ideas into their own goods, increasing their worth. Though originally intending to invite only neighboring countries to this exposition, the plan soon escalated to include the global environment. As organization and sponsorship was planned out, the matter of where to host such a large and ongoing event arose. We will write a custom essay on Worlds Fair Crystal Palace specifically for you for only $16.38 $13.9/page Order now Ideally, it was to take place in London, to sort of show off the best of the country and impress in-coming visitors. The problem was that London was already built up and filled in, and little open space remained for the needed time period. It was decided soon that a portion of Hyde Park would provide the needed location, so it looked as though the problem of a site had been solved. However, there were many opposers to the plan. In general, foreign imports coming in such great quantities could undermine British industry. More specifically, the site itself was questioned. Though the park offered enough space, the British were very protective of their parks, and thought that the fair would lower property values of the highest portion of town, as well as permanently disfigure the natural area. Amongst the criticisms, the committee still had to plan a structure to hold the event. Most ideas involved a long, one-story building made of brick. The problem was that it looked far too solid and difficult to remove later not to mention that it probably could not be built in time. Further debate and redraftings didnt help speed the project along, either. Paxton submitted his idea late in the game, but was almost instantly adopted. It was so cost-effective, the fairs planning committee had to accept his proposal. The overall design resembled a greenhouse, as he had grown up planning gardens. This was the first building to use glass as a primary material, and while it solved the concern of proper lighting needed, it was a bit of surprise to most people because it was considered unsafe. Plus, a tax had recently been placed on the material, so the amounts needed were questionable. However, the plan was embraced by the contractors, mostly on the merit that the sections of the building were all pre-fabricated modules, able to be built anywhere. Then, the portions would be shipped to the parks site and installed to the base already formed there. The speed of the erection amazed many people. Paxton wanted people to even let people in free once the exposition officially opened, but these idea was not even considered by anyone but him. He valued invention over beauty, but tried to show that invention could even redefine aesthetics. The plan apparently worked, and the media dubbed the building, The Crystal Palace.
