Besides MSXML and SAX for Pascal, can you recommend a SAX parser for Delphi? It would be great if it could be used in cross-platform applications with Free Pascal. ...
Hello, I have an ISAPI application that needs to write to the standard windows event log. The code works just fine when in a user mode process but, as soon as it runs from the ISAPI application, it generates an access denied error when calling RegisterEventSource (no matter what event source I pass it: "Application" fails as surely as a...
Hi, I've created a simple class and got a little problem: I just want to use the method "findComponent' from the classes-unit. I've included the classes unit, but Delphi can't find the findComponent-method. Why? I'm sure that's a very simple problem... unit U_Test; interface uses Windows, Messages, SysUtils, Variants, Classes, Graph...

I'm using Report Builder (Server) to run my reports. We currently host the component in a windows service, now the web tier we have is passing some information through to the server, the usual stuff like the report to run etc, but also the database server on which to run the report. We seem to be able to pick up these properties in t...
Hi, My application uses TDbChart and ADO. I was wondering, for deployment, do I need to include BDE files too? Do you know other charting tools that can be used with ADO (freeware preferably)? I just need simple charting tool. TDbChart is a good one, but if I need to deploy BDE files too, I think it's becoming too bulky and complicated...

Hi there, I have the "luck" to work with quikview, and I have to control it via the ocx component qlikOCX. I've imported the the OCX component into my (delphi 2009) IDE, and now I can simply drag an TQlikOCX object to my form and use it. Unfortunately, when I do something simple like procedure TForm1.Button1Click(Sender: TObject); be...
OK, this should be easy, but I do not find the solution, at least not in the not so good documentation.. In a TTaskDialog, you have the option to add one check-box. You can control its initial state by means of the tfVerificationFlagChecked flag in Flags. But how to get the state after the dialog has been Executed? Of course one can use...
I have a small client-server application, where server sends some messages to the client using named pipes. The client has two threads - main GUI thread and one "receiving thread", that keeps receiving the messages sent by server via the named pipe. Now whenever some message is received, I'd like to fire a custom event - however, that ev...
When anti-virus software is running during the installation of my software certain components do not get installed correctly. I always tell the users to turn it OFF first.

It might seem natural to use Ctrl++, Ctrl+-, and Ctrl+0 as shortcuts for an application's zoom in, zoom out, and restore default zoom (typically 100 %) actions. Now, in Delphi, I am able to assign Ctrl++ and Ctrl+0 as shortcuts. The former, though, requires that the plus sign of the main part of the keyboard is used; the plus sign of the...
The program WinDirStats (written in C++, see http://sourceforge.net/projects/windirstat/ ) has at the top a control that combines a tree-like structure (The column "Name", first on the left) with other types of data (graphic bar in column "Subtree percentage") and other text columns. My question is, using Delphi 7, which control should ...
