In a Delphi 2007 program I am using a TMainMenu referencing actions in a TAction list. I have prefixed the hotkeys of all main captions with an ampersand: &File | &Edit | Ev&aluate | ... In design view these hotkeys are underlined as I would expect, but when I start the program they no longer are underlined but they work nonetheless. ...
We have the following in our codebase, in a component file: {$IFDEF ADO} FDatabase : TADODatabase; {$ELSE} FDatabase : TODBCDatabase; {$ENDIF} The reason is that for various legacy applications, one or the other type of database connection and set of classes is to be used. However, while configuring a new machine, it seems that our c...
This is an interesting problem that I’ve not been able to solve yet. I am writing a client that communicates across the Internet to a server. I am using the TIdTcpClient Internet Direct (Indy) component in Indy 10 using RAD Studio 2007 native personality. To get data from the server, I issue an HTTP request using SSL over port 443 whe...
Sure I've seen this done before but off-hand I can't find any examples. I've got a TListView, set in 'report' viewstyle. It has about half a dozen subitems, and one thing we'd like to do is have the 'hint' (tooltip) on the listview dynamically show another field of data. That is, each time you move the mouse over any given row, the 'hin...
How I can find out the position (row and column index) of controls inside TGridPanel? I'd like to use common OnClick event for number of buttons and need to know the X,Y position of the button. I'm using Delphi 2007. ...
Very simple problem. I have a Delphi application and I want to restrict access to this by requiring users to log on using CardSpace. Basically, I need to extract the ID, name and address information from the cardspace card. The use of CardSpace is a requirement from a customer and I just want to know if: Can CardSpace be easily used f...
I have a Firebird database (running on server version 2.1.3) and am connecting to it with Delphi 2007 using the DBExpress objects (using the Interbase driver) One of my tables in the database looks something like this CREATE TABLE MYTABLE ( MYDATE Timestamp NOT NULL, MYINDEX Integer NOT NULL, ... Snip ... PRIMARY KEY (MYDAT...
A very simple situation. I'm working on an application in Delphi 2007 which is often compiled as 'Release' but still runs under a debugger. And occasionally it will run under SilkTest too, for regression testing. While this is quite fun I want to do something special... I want to detect if my application is running within a debugger/reg...
The situation is simple. I've created a complex Delphi application which uses several different techniques. The main application is a WIN32 module but a few parts are developed as .NET assemblies. It also communicates with a web service or retrieves data from a specific website. It keeps most of it's user-data inside an MS Access databas...
In multi thread programming we can find different terms for data transfer synchronization between two or more threads/tasks. When exactly we can say that some algorithm is: 1)Lock-Free 2)Wait-Free 3)Wait-Freedom I understand what means Lock-free but when we can say that some synchronization algorithm is Wait-Free or Wait-Freedom? I ...
Microsoft has this nice little feature called CardSpace. This is a Microsoft implementation of InfoCards. Microsoft has a nice document which explains how it can be used, which is useful. And doing a Google search doesn't provide me many useful answers but it does provide an enormous amount of noise. (Mostly because people wonder what it...
I am just wondering if I'm doign something that might be bad, although it seems a very practical solution to me... I have two forms which the user will have to walk through. The user clicks on a button and form1 pops up. The user presses OK and the second one pops up. The user click OK again and the screens are gone. Or the user clicks ...
I have a Delphi 2007 application that has a TAnimate control with a FindFile Common AVI. It works perfectly when the application is run on Windows XP, but nothing ever appears on Windows 7. I've heard it now requires its own thread, but I am not certain. Does anyone know how to get TAnimate's Common AVI control to work on Windows 7 (or ...
I am familiar with Jeff Atwood's article about how errors are always the programmer's fault, but I believe I have really and truly found a bug in a Delphi .pas file. Specifically, I'm using Delphi 2007, and the error is on line 955 of the DBCommon.pas file, which on my machine is located here: C:\program files\codegear\rad studio\5....
This one’s a head scratcher. Here’s the deal. While deploying a beta copy of an ASP.NET application built with Delphi 2007 for .NET to a test server I encountered an odd problem. The application was unable to start because it could not load the correct version of an ADO.NET data provider that I was using. Only by including a version o...
I am trying to debug an application in Delphi 2007 on a Vista machine. The application was originally written for XP so it must be run with administrator privileges. I know that I could put some information into the manifest or update the code but I am looking for a quick fix that can be used in all my projects. Does anyone know if ...
Simple situation. I'm trying to write my own blog with a minor twist. Part of the blog will be controlled from a client application instead of a web interface. Basically, I'm still in the design phase and haven't written a single line of code. But I'm trying to combine several techniques into an interesting exercise in software developme...
I've just received an assignment to upgrade an old Delphi 3 project that I wrote in 1999 to a newer version and add features (I previously discussed this in related questions here and here). I was assuming that the appropriate route would be to first upgrade my development environment to Delphi 2010 and then port the application. I'm n...

I've begun working with using Lazarus to make some simple utilities for my own use on Ubuntu 9.10. I know many people like the modular Delphi 7 layout, but I hate it. I find it annoying and disruptive. I dislike using Gimp for the same reason. I'd also prefer to have the Delphi 2007 palette menu. Is this possible within the latest versi...
