I find that the HLP file isn't really a tutorial, and the demos are so rich to the point where I can't get started quickly and see if QuantumGrid fits my needs. Would someone happen to...
I just downloaded the Delphi 2010 iso from my SA-subscription and wanted to install it in addition to my other Delphi installations on my notebook computer. Unfortunately it refuses to install because the machine is running Windows 2000. Is it possible somehow to get it to install it anyway? Or is there a technical reason why it might n...
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...

IdFTP.TransferType := ftBinary; IdFTP.Get(ASource, ADest, AOverwrite); I expect that both text and binary files can be downloaded using the binary mode. However it looks like t...
I just discovered that the Delphi TRibbonComboBox doesn't have an item index, and it should. I'd like to fix this locally at least for the unit, and I think Delphi 2009 added a way to introduce new methods to an outside class without having to descent from the class, but I can't remember how. Is there a way to add 'function ItemIndex: ...
