Create an Internet Shortcut (.URL) File Using Delphi

Create an Internet Shortcut (.URL) File Using Delphi Unlike regular .LNK shortcuts (that point to a document or an application), Internet Shortcuts point to a URL (web document). Heres how to create a .URL file, or  Internet Shortcut, using Delphi. The Internet Shortcut object is used to create shortcuts to Internet sites or web documents. Internet shortcuts are diverse from regular shortcuts (which contain data in a binary file) that point to a document or an application. Such text files with a .URL extension have their content in INI file format. The easiest way to look inside a .URL file is to open it inside Notepad. The content (in its simplest form) of an Internet Shortcut could look like this: [InternetShortcut] URLhttp://delphi.about.com As you can see, .URL files have an INI file format. The URL represents the address location of the page to load. It must specify a fully qualifying URL with the format protocol://server/page.. Simple Delphi Function to Create an .URL File You can easily programmatically create an Internet shortcut if you have the URL of the page to which you want to link. When double-clicked, the default browser is launched and displays the site (or a web document) associated with the shortcut. Heres a simple Delphi function to create a .URL file. The CreateInterentShortcut procedure creates a URL shortcut file with the provided file name (FileName parameter) for the given URL (LocationURL), overwriting any existing Internet Shortcut with the same name. uses IniFiles;...procedure CreateInternetShortcut(const FileName, LocationURL : string) ;begin   Ã‚  with TIniFile.Create(FileName) do   Ã‚  try   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  URL,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  LocationURL) ;   Ã‚  finally   Ã‚  Ã‚  Ã‚  Free;  Ã‚  end;end; (*CreateInterentShortcut*) Heres a sample usage: //create an .URL file named About Delphi Programming //in the root folder of the C drive //let it point to http://delphi.about.com CreateInterentShortcut(c:\About Delphi Programming.URL , http://delphi.about.com ) ; A few notes: You could save a web page as MHT (web archive) and then create a .URL shortcut to be able to access an offline version of a web document.You must provide a full file name, along with the .URL extension, for the FileName parameter.If you already have an Internet Shortcut you are interested in, you can easily extract the URL from an Internet Shortcut (.url) file. Specifying the .URL Icon One of the neater features of the .URL file format is that you can change the shortcuts associated icon. By default the .URL will carry the icon of the default browser. If you want to change the icon, you only have to add two additional fields to the .URL file, as in: [InternetShortcut] URLhttp://delphi.about.com IconIndex0 IconFileC:\MyFolder\MyDelphiProgram.exe The IconIndex and IconFile fields let you specify the icon for the .URL shortcut. The IconFile could point to your applications exe file (IconIndex is the index of the icon as a resource inside the exe). Internet Shortcut to Open a Regular Document or an Application Being called an Internet Shortcut, a .URL file format does not permit you to use it for something else- such as a standard application shortcut. Note that the URL field must be specified in the protocol://server/page format. For example, you could create an Internet Shortcut icon on the Desktop that points to your programs exe file. You only need to specify the file:/// for the protocol. When you double click on such a .URL file, your application will be executed. Heres an example of such an Internet Shortcut: [InternetShortcut] URL file:///c:\MyApps\MySuperDelphiProgram.exe IconIndex 0 IconFile C:\MyFolder\MyDelphiProgram.exe Heres a procedure that places an Internet Shortcut on the Desktop, the shortcut points to the *current* application. You can use this code to create a shortcut to your program: uses IniFiles, ShlObj;...function GetDesktopPath: string;//get the location of the Desktop foldervar   Ã‚  DesktopPidl: PItemIDList;   Ã‚  DesktopPath: array [0..MAX_PATH] of Char;begin   Ã‚  SHGetSpecialFolderLocation(0, CSIDL_DESKTOP, DesktopPidl) ;   Ã‚  SHGetPathFromIDList(DesktopPidl, DesktopPath) ;   Ã‚  Result : IncludeTrailingPathDelimiter(DesktopPath) ; end; (*GetDesktopPath*) procedure CreateSelfShortcut;const   Ã‚  FileProtocol file:///; var   Ã‚  ShortcutTitle : string;begin   Ã‚  ShortcutTitle : Application.Title .URL;   Ã‚  with TIniFile.Create(GetDesktopPath ShortcutTitle) do   Ã‚  try   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  URL,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  FileProtocol Application.ExeName) ;   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  IconIndex,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  0) ;   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  IconFile,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Application.ExeName) ;   Ã‚  finally   Ã‚  Ã‚  Ã‚  Free;   Ã‚  end;end; (*CreateSelfShortcut*) Note: simply call CreateSelfShortcut to create a shortcut to your program on the Desktop. When to Use .URL Those handy .URL files will be useful for virtually every project. When you create a setup for your applications, include a .URL shortcut inside the Start menu- let users have the most convenient way to visit your website for updates, examples, or help files.

Basic Video Streaming Problems Essay Example | Topics and Well Written Essays - 500 words

Basic Video Streaming Problems - Essay Example However, there are several drawbacks related to the concept of video streaming. Video streaming has its limitations on the internet because internet does not give any surety of any fixed bandwidth, delay or packet loss. It works on a â€Å"best effort service† (Apostolopoulos et al. 2002). These are considered to be variable factors that change with respect to the quality of internet connection. There have been many researches carried out over the years to induce more reliability and consistency in video streaming. These three issues are discussed in detail: As stated earlier, the bandwidth between two nodes is variable and might not be known. This variability causes problems in the traffic flow from one point to the other (Wu et al. 2001). If the sender sends data at a rate which is faster than the available bandwidth then congestion and low quality streaming is resulted. On the contrary, if the sender sends data at a rate which is slower than the available bandwidth then the receiver decodes a sub-optimal video quality (Apostolopoulos et al. 2002). A strategy to overcome this problem is to ensure a bandwidth that is acceptable to both the nodes; this can be done by estimating the available bandwidth and striking a balance between the estimated bandwidth and video bit rate transferred over the link. The degree of this issue varies from packet to packet. The variation in the delay of every packet depends on its respective queues on different routers. If there exist some variations in the end-to-end delays then it is known as delay jitter (Apostolopoulos et al. 2002). The main reason behind this problem lies in the fact that the receiver is designed to decode and thus display frames at a certain rate. Some frames may arrive at the receiver late due to this delay jitter; this can create a problem at the receiver because he is programmed to decode the frames at a certain rate. These late frames will cause jerks in the display of

Federal Reserve Paper Essay Example | Topics and Well Written Essays - 750 words

Federal Reserve Paper - Essay Example 3. Maintaining the stability of the financial system and containing systemic risk that may arise in financial markets. 4. Providing financial services to depository institutions, the U.S. government, and foreign official institutions, including playing a major role in operating the nation's payments system. Discussion Since the Federal Reserve Act of 1913 the Federal Reserve has been in governance of monetary policy. The policy is controlled by maintaining open market operations, reserve requirements, and discount rates (Monetary Policy, p.1). In section 2A of the Federal Reserve Act the objectives of the monetary policy read â€Å"The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy's long run potential to increase production, so as to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates† (About the Fed, p. 1). In this process the primary function of the central bank is to increase the credit and cash flow. The way this task is completed is by acting as a hub for the Federal Open Market Committee (FOMC). The Federal Reserve Bank relinquishes the funds from depository institutions into public funds. ... 1). Generally in order for the central bank to be successful at this agenda there has to be something of monetary value. The basic function of money is used as a stake horse for the Reserve bank. When the economy is in high demand of currency the Federal Reserve Bank issues it to institutions. When the demand for cash is low the bank will recover money from institutions and allow them to access a credit account (The Structure of the Federal Reserve, p. 1) These involvements along with the influence of the monetary policy will have a visible impact on the economic state. In light of the recent recession there has been some progress made toward fulfilling the monetary policy. The Federal Reserve Chairman, Ben S. Bernanke, made a testimonial over the recent effects of the economic recovery. Based on his report the new monetary policy has not yet had a positive effect. According to the report given by Bernanke the objective for the Federal Reserve to maximize employment and stabilize pri ces is near but offset by an expected decline of employment in 2011. It is expected that with the policy in place the unemployment rate will go down to 8% by 2012. The effects of the currently high unemployment rates force the economy into lower inflation periods. That force places us in range for deflation and is the cause of less production (Bernanke, p. 1). To enforce a consistent upward turn in the objectives of the monetary policy several Acts have been implemented. Of the lot, the Government Performance and Results Act Strategic Planning Document (2008-2011) outlines that the monetary policy goals will be met using the following objectives: 1. Stay abreast of recent developments in and prospects for the U.S. economy and financial markets, and in those abroad, so that monetary

My Antonia Essay: Women on the Frontier -- My Antonia Essays

Women on the Frontier in My Ántonia In 1891, marking the elimination of "free land," the Census Bureau announced that the frontier no longer existed (Takaki, A Different Mirror, 225). The end of the frontier meant the constant impoverishment, instead of the wealth they had dreamed of, for a large number of immigrants from the Old World: they came too late. My Ántonia, however, illuminates another frontier, a frontier within America that most immigrants had to face. It was the frontier between "Americans" and "foreigners." The immigrants were still "foreign" to the "Americans" who came and settled earlier. They had to overcome the language and cultural barrier and struggle against the harsh conditions of life. The novel focuses on the ironic moment that the frontier spirit - a uniquely American one - is realized through "foreigners." Furthermore, it is women, the "hired girls," who are put in the foreground in the novel. What has made America is the foreign within, or rather, the foreign women on the fron tier. The division between the "Americans" and the "foreigners" is found throughout the novel. Even though naturalized, immigrants are still "Bohemians," "Russians," "Norwegians," and so on. They are foreigners in conception as Jim Burden's grandmother says, "If these foreigners [Norwegians] are so clannish, Mr. Bushy, we'll have to have an American graveyard that will be more liberal-minded...."(emphasis mine 73). According to her, the demarcation between foreigners and Americans is purely cultural: as far as foreigners are not clannish and liberal-minded like "Americans... ...an: the heterogeneity within one Bohemian-American family. Children learn Bohemian, the parents' mother tongue, first, and English when they go to school. They eat both American and Bohemian food. Mother from country and father from city, children are open to a wide experience than their parents. Ántonia's first daughter, although married and left the house, is another significant heterogeneity of the family. As the first Mormons scattered sunflowers seeds on their ways to freedom, Ántonia, a woman on the frontier, has raised many future citizens of America. Even though they claimed the end of the frontier, her children might confront another kind of frontier, but it is clear that it is not the same frontier on which their mother has had to stand. The frontier comes back, but always in a different shape.
