I am using Delphi 2009. On a huge project 300+ units, 5 third party components, many libraries, very often the IDE gets frozen for seconds, very often when "intellisense" (I don't remember how it is called) tries to give me suggestions. Is there a way to improve the performance? I will try also the following improvements: 1) format m...
I've written a simple web servrice application in Delphi using THTTPSoapDispatcher and THTTPSoapPascalInvoker. Everything works ok, except that I don't understand how to handle exceptions. So whenever an exception occurs inside the service method, the following SOAP response is generated: <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:S...

I have a "wide" TPanel with several buttons on it (essentially a tool bar). All the buttons have Align=Left. I have created a function which will resize the buttons to the same size and calculate the width of them so they fill the entire TPanel. I call this function in the OnResize event handler of the TPanel. procedure ScaleButton...
Hello. When you create a TThread descendant using the tool palette in your BDS, you can provide a name for the thread. Here's the auto-generated code. You just call the SetName() function in the Execute method and the thread calling this method is given a name in a kind of weird way... {$IFDEF MSWINDOWS} type TThreadNameInfo = record...

Is there a way to merge two Delphi projects into one? In one project I have 3 different forms with different stuff on them, but I would like to add a program I have coded a while ago into a new form in my program. ...
Hello I am currently working on a program and I would like to add a button that would allow the user to Load a picture from his computer into the Image procedure TForm1.btnLoadPicClick(Sender: TObject); begin img1.Picture.LoadFromFile( 'test.1'); img1.Stretch := True ; I was using this code but it limits the person to only being ab...
Hi, so far I thought that any operation done on "shared" object (common for multiple threads) must be protected with "synchronize", no matter what. Apparently, I was wrong - in the code I'm studying recently there are plenty of classes (thread-safe ones, as the Author claims) and only one of them uses Critical Section for almost every me...
Application compiled with Delphi 2010 (Windows XP3 machine) don't run on Windows 7. However, it runs fine on Windows XP. I see no special message when the program is compiled with D2010. Third party component used are AnyDAC and wwDBGrid (woo2wool). Here the event message produced when executed on W7 (the program just don't start, win...
I need to know if all characters in a string are equal (formed by the same character). the function must return true or false depending if all the elements of the string are equal to an particular char. I wrote this function that works well, but I'm looking for a more optimal (fastest) solution, the strings can have thousands of chars...
I have a Delphi application that reads/writes to a COM port connected to a large hardware device, so I don't usually have the hardware available during development. That said, the communication protocol is fairly simple, so I can generally do the development and have someone onsite test it, and it usually works. Occasionally I run into...
Is there a template engine for scripted code generation like Apache Velocity or Freemarker (see examples below) which I can use in Delphi applications? (not in the IDE - I am not lookig for a OTA based solution, or Delphi code templates) The template engine would bind Delphi objects to a template and replace the script variables, and ex...
Simple issue, actually. Just curious if others recognize the problem and perhaps have a working solution for it... I have a simple XSD file which I use to define a configuration file that is used by my application. I need to bind this schema to my project and this is done using the XDBW. In Delphi 2007, this wizard would just recognise ...
hi, I'm using Delphi 7, and I want to create a custom warning message(which will be showed at compilation), so I can warn other programmers on some modifications. I've searched on the internet but i didn't found anything relevant. Other solutions, are welcomed as well, as long other programmers are warned about things I want, when the...

Hi, for these 2 libraries, Delphi Encryption Compendium v 5.2 TurboPower Lockbox v 2.07 I tested their Rijndael DCB/CBC algorithm with "AES Known Answer Test (KAT) Vectors" obtained at NIST website (http://csrc.nist.gov/groups/STM/cavp/index.html) But, both of these libraries failed the tests. Not sure if it was my testing that has...
Hi I'm having problems with my SendMessage. It seams like the message never reaches my form (I'm using Winspector Spy to see which messages that are registered in my form), which is strange because I'm shure I'm sending to the correct Handle for the current form. The SendMessage is within a dll but that should not have any thing to ...
Update: gutted the question with a simpler example, that isn't answered by the originally accepted answer Given the following class, and its ancestor: TComputer = class(TObject) public constructor Create(Teapot: string=''); end; TCellPhone = class(TComputer) public constructor Create(Cup: Integer); overload; virtual; co...
