• Delphi 6: How to search a dynamic array for sub-string quickly?

  - by Robert Oschler

  How can I search a dynamic array of char in Delphi 6 for a sub-string and get back an index to a match, not a pointer? I've seen functions in Delphi 6 that do this for strings but not for dynamic char arrays. There is a function called SearchBuf but that function returns a PChar pointer to the match location when what I need is the array index of the match. Thanks.

  - by Nate Pet

  This question already has an answer here: What and When to use Tuple? 5 answers I was looking at examples online of Tuple but I do not see any ideal use of it.

  - by b3y4z1d

  If I made a program that stores strings on a text file using the "list"-function(#include ), and then I want to copy all of the text from that file and call it something(so I can tell the program to type in all of the text I copied somewhere by using that one variable to refer to the text), do I use a string,double,int or what do I declare that chunk of text as?

  Is it possible to have the compiler automatically convert my Enum values to strings so I can avoid explicitly calling the ToString method every time. Here's an example of what I'd like to do: enum Rank { A, B, C } Rank myRank = Rank.A; string myString = Rank.A; // Error: Cannot implicitly convert type 'Rank' to 'string' string myString2 = Rank.A.ToString(); // OK: but is extra work

• How can I use the compile time constant __LINE__ in a string?

  I can use __LINE__ as a method parameter just fine, but I would like an easy way to use it in a function that uses strings. For instance say I have this: 11 string myTest() 12 { 13 if(!testCondition) 14 return logError("testcondition failed"); 15 } And I want the result of the function to be: "myTest line 14: testcondition failed" How can I write logError? Does it have to be some monstrosity of a macro?

  - by bks

  i just moved from C to C++, and now work with lists. i have a class called "message", and i need to have a class called "line", which should have a list of messages in its properties. as i learned, the object's properties should be initialized in the constructor's initialization list, and i had the "urge" to initialize the messages list in addition to the rest of the properties (some strings and doubles). is that "urge" justified? does the list need to be initialized? thank you in advance

• .NET IsValidXml Extension Method Performance

• Does the java JFC hash table use seperate chaining resolution? Can I traverse each list in the table

  - by Matt

  I have written a program to store a bunch of strings in a JFC hash table. There are defiantly collisions going on, but I don't really know how it is handling them. My ultimate goal is to print the number of occurrences of each string in the table, and traversing the bucket or list would work nicely. Or maybe counting the collisions? Or do you have another idea of how I could get a count of the elements?
