I created a class that opens a COM port and handles overlapped read and write operations. It contains two independent threads - one that reads and one that writes data. Both of them call OnXXX procedures (eg OnRead or OnWrite) notifying about finished read or write operation. The following is a short example of the idea how the threads...
I've found several implementations for single producer-single consumer, but none for multiple producer-single consumer. Does a lock-free queue for "multiple producers-single consumer" exist for Delphi? ...

I just played around with the new Delphi 2009 ribbon, added a few pages, groups and actionclients (large buttons) to it. I created some transparent 32x32px PNGs in Photoshop and put them into a TImageList (set to cd32bit). I added this list to the Actionmanager's Images property, to show them on the buttons. At designtime the icons in th...
I've got a routine that deletes a folder and everything in it. After deleting all the files, the last thing it does is: if not Windows.RemoveDirectory(pname) then raise EInOutError.Create(SysErrorMessage(GetLastError)); Unfortunately, I tend to get an error from this if I have an open window in Windows Explorer displaying the folder...
I use Help & Manual to create web help (HTML) files. I would like to link this to my Delphi 2007 application so that it pops up when users press the F1 key, and ideally, to pop up to a context sensitive spot. This is what I've tried: Adding the HTMLHelpViewer unit to the uses clause of the main form. Setting the HelpFile property to...
Hello. I am trying the devart ibdac components but I am having a little issue with the IBCTable component. On tables with autoinc (trigger based) when I try to post the data it says that the field with the autoincrement must have a value, whereas if I use a SQL query to insert it everything works fine. Is there any workaround for this? ...
I want to reset the "checked" property of all TAction objects of a ribbon to false when clicking on any ribbon button and then only set it true on the pressed button. But I did not yet find a way to access all the "checked" properties of the ActionManager's Actions. I think I need to loop through the actionmanager's actionlist... however...

Hi, I have a Delphi application which loads a Google map in a TWebBrowser: with WebBrowser1.Document as IHTMLDocument2 do with parentWindow do ExecScript('map.setCenter(new GLatLng(51.15917, 4.13889),10)', 'JavaScript'); Any idea of how to get the extents of the map in my application? TIA Steven edit Rob's answer points to a pa...
This question may seem trivial, but I hope you won't ignore it. Before destroying a TThread object it is usually necessary to wait until the thread that called the TThread.Execute() method finishes, for only then can we be sure that, for instance, the objects destroyed inside the class's destructor are no longer accessed. Therefore it is...
I am trying to make a Delphi client (Delphi 2006) to communicate with a service written using WCF. Service is damn simple with just one function. Technically like below: [ServiceContract (Namespace = "http://www.company.com/sample/")] public interface IService { [OperationContract] string GetNumber (string name); } I have host...

(I use all my own frames and uni...
I have a "simple" task. I have an existing project with a web service written in C# which has a method that will send a huge XML file to the client. (This is a backup file of data stored on the server that needs to be sent somewhere else.) This service also had some additional authentication/authorization set up. And I have an existing D...
A client has a lashed-together 'alerter' system based around batch files and 'NET SEND' commands. He edits the batch files (adding/removing users) as necessary. His requirements are getting a bit more complex now; he wants users to be able to drop in and out of the notifications, during the day. I got to thinking about some kind of tray...
I'm using Delphi to make an XLL add-in for Excel, which involves making a lot of calls to the Excel4v function of xlcall32.dll. However, as I'm guessing very few Delphi experts here have worked with that specific API, I'm hoping that the problem might have been observed in other APIs too. In C, specifically in the xlcall.h file that co...
