Radiogroup
Hello, I have a page control with some tabs. On one of them I have a radiogroup. I want at the begin one item of radiogroup to be disabled, I do that: Rdgrp.Controls[i].Enabled:=false; however since the radiogroup is not in the "enabled" page, it seems that the Controls is empty (also confirmed by controlcount =0). It works only if the page is the active one. It should be something related to the completion sequence of object creation, is there a way to overcame this problem ? is there a "loaded" function on which write such code be sure the object is created ? thank you in advance.

If you prefix your statement with Rdgrp.HandleNeeded; it might work. -- Peter Below (TeamB)

A general question about supporting offline databases
I am a bit of a newbie with Delphi databases, we've been using Delphi for 15 years but we have always used a proprietary binary data format. We now want to switch to an SQL file format. For now we're working with SQLITE, so the Java and C# guys in our shop can read the file too. We have all the latest tools now, XE5 with FireDAC, Datasnap, REST etc. I am very, very impressed with what we can do now. Currently, we have a Delphi desktop app that controls the data file, and use XMLRPC calls from the clients to send and receive transactions. We have what we call a "refresh&...

Delphi 4 to Delphi 2009
Hello, Thanks to all who answered my previous question. That was a great help. And atlast our client agreed to upgrade our delphi version from 4 to Delphi 2009. *Sigh*. But before that, I need to give the estimation and cost regarding the migration to delphi 2009. Can anyone tell me is there any tool to migrate from delphi 4 to delphi 2009 or just I need to compile our Delphi 4 application in Delphi 2009. I have read from the delphi 2009 feature matrix that Delphi 1 through Delphi 2007 import is possible in delphi 2009. But i am not that sure considering the size of our application. ...
