I've been working in Delphi 7 for the last 6 years now and have learnt to merely submit to the instablity of the IDE. For example, there are particular projects I've inherited which, when working on, I cannot use the CTRL+SPACE dropdown symbol list in the Delphi editor without getting an Access Violation error, this would easily top my l...

Leading on from the answer to another question about bugs in the Delphi IDE, does anyone know if there is a way to improve the multi-threaded debugging functionality of the IDE, or if not, at least why it is so bad on occasion? When you have multiple threads within a program, stepping through the code with F7 or F8 can often lead to eit...
If I implement an interface on a base class will it be inherited by its sub classes, I know the functions/procedures will be, but I am more interested in whether I will be able to cast the subclass to the interface and then back to its original class. What I am hoping I can do is pass objects of different base classes to a function, and...
Why I always get WSAETIMEDOUT error in this code : var fUDPBuf: array [1..UdpPacketSize] of byte; {...} UDPSocket := TUDPBlockSocket.Create; UDPSocket.Bind(UDPIP, UDPPort); if UDPSocket.LastError = 0 then Raise EDevFail.Create(Format(SPortFailed, [UDPPort])); while not Terminated do begin BytesRead := UDPSocket.RecvBufferEx(@fUDPBu...

I was doing some customization to my forms, since I want them with some published properties appear on Object Inspector. I've done the simple way: create the form, put it on object repository, created a package to register it with RegisterCustomModule.

I need to insert 800000 records into an MS Access table. I am using Delphi 2007 and the TAdoXxxx components. The table contains some integer fields, one float field and one text field with only one character. There is a primary key on one of the integer fields (which is not autoinc) and two indexes on another integer and the float field....
I thought about creating my own, but there are many details to consider to make it 100% compatible with Java .properties files, so I'm asking first. ...

I am running on Windows 2003 server, SQL Server 2k personal edition, when I look on my MDAC version in the registry, I see version 2.8 alread...
I wish to download a web page, which may be in any possible text encoding, and save it as UTF16LE. Assuming I can determine the text's encoding (by examining the HTTP header, HTML header, and/or BOM), how do I convert the text? I am using Delphi 2009. Unfortunately, the help files do not explain how to get from any encoding to a Unico...

Hi, I'm still on D2007 and have need to create a unicode enabled virtual keyboard. So I'm using TMS's unicode buttons to simulate the keys, but what I want to avoid is having to assign mmo.Lines.Text := mmo.Lines.Text + Button1.Caption; ~50 times. There just has to be a better way to send one character at a time to the memo. Is there ...

How can I add a background image to my delphi form? I added a TImage, but now the labels aren't visible any more, and the texts of my checkboxes are in a blue "box" (blue is the background color i chose). This blue doesn't look very good on the background image, and the hidden labels also don't look good. How do I fix these problems? ...
I am in the process of porting a Delphi 2006 app to Delphi 2009. Out of the box support for unicode has been easy - almost no work required. Most 3rd party controls already have Delphi 2009 updates available. Rave Reports (latest version 7.6.1, available here) has also been updated, but I cannot seem to get it to correctly display RTF t...
