Hi How can I display a preview (almost like a hint) of an image when I hover the mouse over an item in a listbox of filenames? I've tried showing a form and loading the image, but when the preview form shows, I lose focus for the listbox which means that when I move the mouse, the preview image does not change when I go to the next item...

Hi, I've been trying to get a soap server up that implements (is that the correct term?) a wsdl specification made by a third party. I have used Delphi's wsdl importer. (Part of) the generated code looks like this: miniPortType = interface(IInvokable) ['{824D172A-9C1F-D202-5B21-4C324553BCF0}'] // Cannot unwrap: // - Input element...

I am responsible for porting a Delphi 2007 application to C# and have absolutely no experience with Delphi. I am wondering what is the difference between the two Indy versions Delphi includes - Indy 9 and Indy 10. At this point I don't even know what an Indy is. Can someone help me out? Are they just different versions of the Delphi Libr...
I've got an algorithm. I'd like to pause it at some point and then continue once the user presses a button. How do I do that? I've browsed the documentation, and searched the internet, but no luck yet. Here's a relevant code snip: if A[i]>A[i+1] then begin Zameni(i,i+1); done:=true; ...
I'm new to Delphi (again - I used Delphi back in 1994). I now have Delphi 2009 Pro. Coming from Java, I find the object inheritance very obscure. My users want tabbed pages with the tabs on the left. But, the TPageControl doesn't allow the tab label direction or orientation to be changed. They want the words on the tabs to read to...
For one particular issue in the architecture of an application I'm working on, interfaces seem to be a nice solution. Specifically, some "business objects" depend on a bunch of settings that are pulled from the database in the actual app. Letting those business objects ask for an interface (through Inversion of Control), and letting a ce...
In code I have developed some years ago I have been using this a lot to close the current form on pressing the Escape key at any moment: procedure TSomeForm.FormKeyPress(Sender: TObject; var Key: Char); begin if key = #27 then close; end; This behaviour is defined for the TForm. The form's KeyPreview property is be set to True to ...
I am using the operator overloading for records in Delphi 2006. (Please don't answer this question by telling me not to.) I have two record types with the implicit operator overloaded. They are both only in the implementation of the module, not exposed through the interface. My problem is, now that they are mutally dependent, I don't ...
I'm trying to modify a legacy Delphi 5 app so that it can be launched either from it's icon/via Explorer, or from the console (command-line). When it gets launched from the console, I want the program to detach itself from the console process, so that the console can continue to execute other instructions without waiting for my program t...

Should I call "inherited" in the constructor of a class derived from TObject or TPersistent? constructor TMyObject.Create; begin inherited Create; // Delphi doc: Do not create instances of TPersistent. Use TPersistent as a base class when declaring objects that are not components, but that need to be saved to a stream or have their p...

I'm aware of some Windows Thread Libs for Delphi(OmniThread Lib, BMThreads, etc). But is there a lib that is built to be cross-platform and that can both be used under Delphi and FreePascal? ...
I have a configuration file that I consider to be my "base" configuration. I'd like to compare up to 10 other configuration files against that single base file. I'm looking for a report where each file is compared against the base file. I've been looking at diff and sdiff, but they don't completely offer what I am looking for. I've con...
The majority of components available for Delphi do not have HTML Help files for Delphi 2009. Many components including some very popular commercial components only have HLP and CHM help files. Many of the third-party components are no longer being actively developed but are used by many developers. As a result there is no IDE help for...
What is the best way to convert an array of bytes declared as TBytes to a RawByteString in Delphi 2009? This code actually works, maybe there is a faster way (without loop): function Convert(Bytes: TBytes): RawByteString; var I: Integer; begin SetLength(Result, Length(Bytes)); for I := 0 to ABytes - 1 do ...

I'd like to make a tool bar with icons that get's bigger when you mouse over them. I don't mind reinventing the wheel, but if anyone can suggest a good: Image Format (not sure bitmaps'll work here and not sure how to do Vectors) Existing Control (pay or free, so long as I can use it in a close source app) Container class (is TPanel suf...
