The code formatter in Delphi 2010 is a useful tool for developing coding standards, or at least this is my opinion, however it has a horrid habit of ruining comments. A nicly commented block like this.. SomeFunction(SomeVaribleWithALongName, // Comment Option2, // Comment ...
Hi There... I have a weird issue when converting code from Delphi 7 to 2010. It has to do with records. The record defined below, when sized in D7, is 432 bytes, and in D2009 (and 2010) it's 496. I know, that an easy solution is to make it a packed record, then all versions come out to 426 bytes... However, we have data stored where ...

The C# control with AutoWrap= False and AutoScroll=True behave like a horizontal scrollable list of controls. How can i mimic the behavior of the C# version of the control ? Thanks, Alin P.S. I know i can use TS...

I'm slightly confused and hoping for enlightenment. I'm using Delphi 2010 for this project and I'm trying to compare 2 strings. Using the code below fails if AnsiStrIComp(PAnsiChar(sCatName), PAnsiChar(CatNode.CatName)) = 0 then... because according to the debugger only the first character of each string is being compared. I.E. if s...

I need three fast-on-large-strings functions: fast search, fast search and replace, and fast count of substrings in a string. I have run into Boyer-Moore string searches in C++ and Python, but the only Delphi Boyer-Moore algorithm used to implement fast search and replace that I have found is part of the FastStrings by Peter Morris, fo...
We are migrating a pretty big application crafted in Delphi 5 (still getting customers using this old versions) that uses BDE to connect to a SQL Server. The decided path to migrating is first Delphi 5 to Delphi 2010, then BDE to dbExpress (or dbGO, still undecided). The problem is that BDE in Delphi 2010 doen't seems to have SERVER NA...

Hi, Today I faced a weird behavior using Indy 10 (shipped with Delphi 2010). Here is the problem: Suppose we have a IdTcpClient in our client, and a IdTcpServer in our server app, and this code in OnExecute event-handler for our IdTcpServer: procedure TForm1.IdTCPServer1Execute(AContext: TIdContext); var AStream: TStringStream; S:...

I maintain a Delphi program which uses typed binary files as its native file format. After upgrading from Turbo Delphi to Delphi 2010, all chars in the record type being stored started being stored with 2 bytes rather than one. The data types being stored are char and array[1..5] of char. So before, part of the file looked like: 4C 20...
After reading the articles "Simmering Unicode, bring DPL to a boil" and "Simmering Unicode, bring DPL to a boil (Part 2)" of "The Oracle at Delphi" (Allen Bauer), Oracle is all I understand :) The article mentions Delphi Parallel Library (DPL), lock free data structures, mutual exclusion locks and condition variables (this Wikipedia art...
