gif := TgifImage.Create; gif.Width := 100; gif.Height := 100; gif.AnimationSpeed := 500; gif.Animate := true; gif.add(image1.Picture.Bitmap); gif.add(image2.Picture.Bitmap); gif.add(image3.Picture.Bitmap); gif.SaveToFile('gif.gif'); This loops just once and the speed is not 500? How to make it loop and set the speed? ...
We have a app which uses HttpWebBrokerBridge, it works fine in Delphi2006 but when I recompile using Delphi2009 I get EDOMParserError exception with message "XML document must have a top level element". I don't have any clues as to what's causing this error. Any clues as to what I should do? Sandeep ...
We use stateful DataSnap servers for some business logic tasks and also to provide clientdataset data. If we have to update the server to modify a business rule, we copy the new version into a new empty folder and register it (depending on the Delphi version, just by launching or by running the TRegSvr utility). We can do this even whi...
A variety of delphi demos I've built today with Delphi 2009 (update 3/4 applied) all seem to result in the client of any localhost web service I try to consume returning an "xml document must have a top level element" error This includes, for example, even a demo as simple as http://blogs.embarcadero.com/pawelglowacki/2008/12/18/38624 ...

I'm trying to open old projects generated in Delphi 7 with Delphi 2009. On some projects, this causes the following error message from the IDE: "An invalid character was found in text content" The affected projects are working fine in the old IDE. How can I solve this? ...
Is there a way in Delphi 2009 to have a section of code conditionally compiled based on a compiler directive. Specifically, I'd like to have code in place that is only included if the range-check compiler directive is turned on. Something like this: {$ifdef RANGECHECKINGISON} [do range checking code here] {$endif} ...
I'm looking for design patterns (GOF, but others would be welcome too) for Delphi 2009. There are some very good and classic articles about Design Patterns in Delphi: http://www.obsof.com/delphi_tips/pattern.html, by James Heyworth (1996) http://blogs.teamb.com/joannacarter/, by Joanna Carter (until 2004) Additionally, the newer Del...
The title says it all, we are considering moving from Delphi 7 to Delphi 2009 and would like to know if QuickReports is still included in the package? ...
For static code analysis tools, it is necessary to know all effective source paths for a given Delphi project, which are defined on project level and in the global IDE configuration. Is there a Delphi library which can collect this kind of project information? As far as I know, the registry settings for the Delphi IDE can be in differ...
Why will this not compile in Delphi 2009? unit VistaFolders; interface uses Windows, ShellAPI, ShlObj; type KNOWNFOLDERID = TGuid; const FOLDERID_ProgramData: KNOWNFOLDERID = '{374DE290-123F-4565-9164-39C4925E467B}'; // downloads folder var SHGetKnownFolderPathFunc: function( const rfid: KNOWNFOLDERID; dwFlags: DWORD;...
When I set the Label's color e.g. on value clRed, the red on it only blink for a while. The color property still has clRed value, but in fact it has default clBtnFace color. Screenshot discribes the problem better. ...
I have a fixed constant array constAry1: array [1..10] of byte = (1,2,3,4,5,6,7,8,9,10); and a dynamic array dynAry1: array of byte; What is the easiest way to copy the values from constAry1 to dynAry1? Does it change if you have a const array of arrays (multidimensional)? constArys: array [1..10] of array [1..10] of byte = . ....
I was looking in Generics.Collections and noticed there was no linked list. Sure they are simple to make, but I thought it was odd there was not one (or I just missed it). Are linked lists just outdated when compared to new modern data structures, or is there a need for a general generic linked list? Does anyone know of one? ...
Hi all, It's a silly point, but I haven't been able to find the answer by myself : In delphi 2009, when I hit the "pause" button ("Suspend program execution") while debugging, the IDE pops the CPU window, and shows me the execution point and stack of the thread which actually stopped the execution, instead of the main thread - which is...
I have a client application that should send notify messages to an optional server application. The client should not be influenced by whether the server appliction exists or not. It should try to connect to the server application and send the notify message and in case of errors it should just silently ignore all errors and continue wor...
I need to display a formatted log in Delphi 2009. The formatting does not have to implement all the features of say html, but a small subset e.g. colour, font style etc. Currently I am using a TRichEdit and my own proprietry tags e.g. this is blue. It is pretty convoluted to get this to work with a TRichEdit as there is no direct access...

My Win32 Delphi app analyzes text files produced by other applications that do not support Unicode. Thus, my apps needs to read and write ansi strings, but I would like to provide a better-localized user experience through use of Unicode in GUI. The app does some pretty heavy character-by-character analysis of string in objects descend...
I am in need of the fastest hash function possible in Delphi 2009 that will create hashed values from a Unicode string that will distribute fairly randomly into buckets. I originally started with Gabr's HashOf function from GpStringHash: function HashOf(const key: string): cardinal; asm xor edx,edx { result := 0 } and eax,eax ...
