I searched the registry. I'd expect the settings in HKEY_CURRENT_USER\Software\CodeGear\BDS\7.0 but didn't find anything. I want to share the settings with my team. Where does Embarcadero save these? ...
The Delphi documentation for MSBuild says /property:name=value sets or overrides project-level properties, where name is the property name and value is the property value. Use a semicolon or a comma to separate multiple properties, or specify each property separately. /p is also acceptable. For example: /property:Wa...

I'm trying to use RTTI to add an event handler to a control, that may already have an event handler set. The code looks something like this: var prop: TRttiProperty; val: TValue; begin prop := FContext.GetType(MyControl.ClassInfo).GetProperty('OnChange'); val := prop.GetValue(MyControl); FOldOnChange := val.AsType<TNotifyEvent...
Let's say I have a record TQuaternion and a record TVector. Quaternions have some methods with TVector parameters. On the other hand, TVector supports some operations that have TQuaternion parameters. Knowing that Delphi (Win32) does not allow for forward record declarations, how do I solve this elegantly? Using classes is not really ...
Those 3 types are very similar... TArray is the generic version of TBytes. Both can be casted to PByteArray and used as buffer for calls to Windows API. (with the same restrictions as string to Pchar). What I would like to know: Is this behavior "by design" or "By Implementation". Or more specifically, could it break in future release?...
I have been trying to get to the bottom of this problem off and on for the past 2 days and I'm really stuck. Hopefully some smart folks can help me out. The issue is that I have a function that I call in a thread that downloads a file (using Synapse libraries) from a website that is passed to it. However, I've found that every once in a...
Hello, I write a component which should store some information relative to the project directory. Every time a property of my component is changed it should write a file. So how can a component determine the current project directory at design time. Thanks in advance EDIT: I want to generate a delphi source file every time a property...
I've got a special combo box with a very long list of items (a few thousand) that has to be calculated when you open it. When I was testing something, I was horrified to find that it took about a minute to open. So I hooked the program (same build, same options) up to Sampling Profiler to see what was taking so long, and it only took a...

I am working on a DLL in Delphi 2010. It exports a procedure that receives an array of variants. I want to be able to take one of these variants, and convert it into a string, but I keep getting ????? I cannot change the input variable - it HAS to be an array of variants. The host app that calls the DLL cannot be changed. It is written ...
Any suggestion for a good unicode string library for Delphi 2010? Such thing as class that would contain a collection of independent functions, basically an encapsulation of functions that manipulate strings (ex: Trimlike, Character removal, Positional, Sub-string, Compare, Informational, Case, Replacement, Manipulation functions etc. )....
When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Doe...
I'm building a program that uses Delphi Packages (BPLs) as plugins, but I'd like to use a custom extension to show that the files have a specific purpose instead of just being BPLs. That works well enough until I end up with one package having a dependency on another. Then the compiler automatically creates the binary with the extensio...
In a Delphi app we have assigned a dataset provider with a TADOQuery, passing parameters to the Query. When the TADOQuery is refreshed with new parameter values these are not being passed to the Dataset Provider. This seemed to work ok in Delphi 5, but we are migrating our application to Delphi 2010 and it seems to have broken this l...
