Oct 04,  · Hello Surprisingly, Google didn't return threads in the defunct gs-wkbg.del newsgroup with "case of string". What is the recommended way to use the "Case Of" structure when checking strings? 2 days ago · December 22, The Case of Delphi Const String Parameters. In Delphi the use of const string parameters is a nice optimization, but as the compiler give us checks for performance, it requires extra developer responsibility. The Delphi Case Statement only supports ordinal types. So you cannot use strings directly. But exist another options like. build a function which returns a Integer (hash) based on a string; using generics and anonymous methods (A generic case for strings) using a function which receive an array of strings (Making a case for Strings, the sane way).

Delphi Programming Series: 30 - Reverse a string

Description: Compares two strings without case sensitivity. The comparison is NOT case sensitive and does not case string delphi 5 the Windows locale settings. The return integer value is less than 0 if S1 is less than S2, 0 if S1 equals S2, or greater than 0 if S1 is greater than S2. This function is obsolete, i. Returns a substring of a string or a segment of a dynamic array. Description: Returns a substring of a string or kd player skins 128x160 segment of a dynamic array. S is an expression of a string or dynamic-array type. Index and Count are integer-type expressions. Copy returns a string containing a specified number of characters from a string or sub array containing Count elements starting at S[Index].

But exist another options like. build a function which returns a Integer (hash) based on a string; using generics and anonymous methods (A generic case for strings) using a function which receive an array of strings (Making a case for Strings, the sane way). Description: The Case keyword provides a structured equivalent to a sequence of if statements on the same variable. The Case statement is more elegant, more efficient, and easier to maintain than multiple if nestings. Version 2. Is used for Records declarations. It is then called a gs-wkbg.de provides a means of mapping two or more differing sets of declarations onto the same section of the. enumerated type is hardly a string it is possible to get the string representation of the values. If, as the poster suggested, one is doing a lot of work with the same string values, converting them to enumerated values and manipulating those can be more efficient and, IMO, can . This is similar to Delphi syntax. The following are valid case statements: Free Pascal allows the use of strings as case labels, and in that case the case variable must also be a string. When using string types, the case variable and the various labels are compared in a case-sensitive way. Jan 08,  · So you can use chars, but not strings in a CASE statement. I agree it could be useful, but other languages, such as BASIC, are less effcient, and often use variants. I checked this out on Delphi 6 and there was no truncation with your code (other than the debugger tooltip). Andreas did likewise on Delphi 4 and Rodrigo did so with Delphi 5. I cannot imagine that it could really be the case that strings in a Delphi 5 OleVariant are truncated at characters. Here are Delphi string handling routines explained: declarations, descriptions, and examples. The comparison is NOT case sensitive and does not consider the Windows locale settings. Delphi leaves the string unchanged if Index is not positive or greater than the number of characters after the Index. If Count is greater than the rest of. If you need to know if strings are the same, OR which string is greater, then use CompareStr. CompareStr is particularly useful when sorting lists, e.g, with gs-wkbg.de(CompareFunc) or gs-wkbg.de(CompareFunc) If you want case-insensitive comparisons, use CompareText. generator to hash the string before putting it through the regular case statement code. Then each branch of the case statement needs to do one or two genuine string comparisons before continuing. I realise we now have 3 platforms to generate code for, but windows and linux both use almost identical assembly code for things, and Dot Net has built in.

The Case statement is more elegant, more efficient, and easier to maintain than multiple if nestings. Version 2. name: string[20]; Case. The constants appearing in the various case parts must be known at compile- time, and can be of the following types: enumeration types, Ordinal types ( including chars) or string types. a Duplicate case label error when compiling this, because the 3 also appears (implicitly) in the range This is similar to Delphi syntax. So you can use chars, but not strings in a CASE statement. I agree it Reply #5 on: August 27, , pm». Quote {$mode delphi}. I have yet to see a reason someone should use a case with string For instance, when run with only 5 elements, the difference drops to %. CaseOfString: Diese Funktion ermöglicht es einem, einen case-Verteiler mit Strings zu realisieren. CaseOfString: This function enables you to realize a case. Here are Delphi string handling routines explained: declarations, The CompareText function compares two strings without case sensitivity. . var s: string; s:= 'ABOUT DELPHI PROGRAMMING'; s:= LeftStr(s,5); // s. The case statement may provide a readable alternative to deeply nested type smaller than 32 bits (string types and ordinals larger than 32 bits Thus, 7, True, 4 + 5 * 3, 'A', and Integer('A') can all be used as. - Use case string delphi 5 and enjoy Delphi Basics : Case command

Jochen Heyla Delphi Developer. Olowofoye Delphi Developer. Quote Maurizio Gagno mga Character by character regards Sven Valt Delphi Developer.

See more best book writing software Pos looks for the first complete occurrence of Str in Source. That's because in theory any method accepting a const string argument and calling other subroutines which can directly or indirectly affect the original string may be affected by the problem. All the best, Timo If Index is greater than the length of S, Copy returns a zero-length string "" or an empty array. Strings is a string list to which all substrings parsed from Content are added. Separators are a set of characters that are used as delimiters, separating the substrings, where Carriage returns, newline characters, and quote characters single or double are always treated as separators. I find this construct useful in other languages - how about a CASE statement that can select on strings i. Case sensitivity or not?
