Hi, Is it possible to do Aspect Oriented Programming in Delphi? I would be interested in native support as well as third party solutions. I don't have a specific problem I want to solve with AOP, but am simply interested in studying AOP. Thanks, Miel Bronneberg. ...
I have a ListView containing file names. These file names need to be draggable to a TreeView, which is a drag/drop inside the application and works with the built in drag/drop support of Delphi - no problem. But I must also be able to drag/drop the ListView items to another application, e.g. Windows Explorer. This also works, for example...
Is there a way to select designtime packages on a project bases? Packages are very useful in large project to keep the build time acceptable, but they are a real pita in those large projects too. When one developer adds a new package, it breaks to build for all other until they install the new package on their machine. And then there is...
Large datasets, millions of records, need special programming to maintain speed in DBGrids. I want to know if there are any ready-made components for Delphi (DBGrids) that do this automatically? EDIT For Example: Some databases have features such as fetch 1st X records (eg 100 records). When I reach the bottom with scrolling, I want t...
I'm not sure why the TSpeedButton has this property but when a TSpeedButton is the only button of a given groupindex, it doesn't stay pressed, whether or not "AllowAllUp" is pressed. Maybe a Jedi control would suffice, but hopefully there's some fix. Any help or anecdotes are appreciated. BTW, I'm (still) using Delphi 7, not sure if t...
I have a report that uses a TChart that I am maintaining. One of the TLineSeries that gets added automatically gets assigned the color clWhite, which is too close to the background (clBtnFace). If I change it, then the next series that gets added takes clWhite. So short of going back and changing it after all the other series are cr...
Since some time, my Delphi debugger became much slower than I was used to before. I noticed this in both Delphi 2007 and 2009, so it seems it's something outside of Delphi itself... What causes this behaviour, and how can I prevent this? ...
I have a problem with a Delphi 2009 project : It can't initialize Indy 10 ! This code worked fine before in Delphi 2007 (although we might have been using an older revision of Indy, but I suspect that has not much to do with it); The initial call to IdWinsock2.InitializeWinSock(), raises this exception (with error code 998) : Project E...
Is there a way to specify which monitor a application appears on in Delphi or C++Builder? I am developing a simple program for a customer, which displays kitchen orders on a secondary monitor, generated by a hospitality system. Currently they need to manually drag the window onto the second monitor after it starts. ...
Following up on this question, I'm working on a large Delphi 7 codebase which was not written very nicely. I'm looking at code like this, as a small example: if FMode=mdCredit then begin Panel8.Caption:='Credit'; SpeedButton3.Enabled:=false; SpeedButton4.Enabled:=false; SpeedButton5.Enabled:=false; SpeedButton5.E...

Hi! When I plug my HP Laserjet 3015, Windows detects the correct model and then tries to install the appropriate drivers. How can I detect the model of connected printer(s)? I don't want to use the list of installed printers because a Zebra printer can be installed with a Generic/Text only driver. I'm a Delphi and C# programmer, so an...

I've created a program in Delphi that uses Google's AJAX Search API to evaluate search phrase occurrences on specific sites, mine included. What surprised me was it doesn't appear Google is indexing some words on my pages, or I am forming my search queries via the API incorrectly. For example the search site:www.delphi.org -"delphi p...
