I was recently asked to install an old app I wrote in Delphi 5 a few years ago, so I dug out my install CD. Unfortunately, it wouldn't install on either of the two machines they had - one running Vista and the other Windows 7. The Vista machine ran the installer OK and installed the program...

I've written quite a few Delphi apps with no real problems, but my latest project has me stumped. I think it's because of too many years using linear programming languages. It's quite complicated, but I'll try and be as brief as possible... Essentially, in my project, I create a list of WAV...

I've searched the web as well as this site and considering the popularity of karaoke, I'm surprised that there's no CDG viewer component available yet for Delphi. I have a number of MP3s with associated .CDG files and although I can call Winamp to hear and view them I'd like to be able to write...

As a hobby, I write DirectX games (or at least try to) which use .X and .3DS models like cars and planes - not in Delphi though. I want to write a small Delphi 5 app which will quickly view the .X models I have on hard disk. I've looked at a few of the Delphi component suites (like Delphix)...

I have the DivX and XVid codecs installed and all my AVI files play back perfectly in Windows Media Player, Winamp etc but when I use the TMediaPlayer component in Delphi 5, they all refuse to play correctly. When you try, there is no sound and the picture is perfect, but it looks like you have...

I have a Delphi program where you select a program - ie Calculator, Notepad etc. A 'Start' button launches the program you selected (let's say it's Calculator). When you click on the 'Stop' button which closes the Calculator. This needs to work regardless of the program chosen by the user...

I've been asked to look into the possibility of converting an old DOS program to Windows by my brother-in-law. I have been given a copy of the old program directories on CD to play with. I'm not 100% sure, but I believe that the old database files are v4.x Paradox For DOS .DB files (if the...

I want to access e-mails on my POP3 server but without downloading them to the PC first. To be specific, I'd like to examine certain lines of an e-mail's header. I know that POP3 is a cut-down version of IMAP, has a limited set of commands and was designed to be an 'offline' mail service so I...

If an exe is launched in my Delphi app in the Form Create section using: ShellExecute(0, 'Open', PChar('Other.exe'), PChar(''), PChar(''), SW_Hide); Is it possible to close it down when my app is closed? I just noticed in my task manager that the exe was running about thirty times! :)...

OK, a week or two ago, my Delphi 5 app started to initialise with a small gap running across the top of the screen and with the same portion of the main form appearing *under* the task bar. It's set to be maximised and I'm using XP Pro. The same problem isn't present running the same app on...

I have a simple MDI app in which the children all have the DreamMemo component on. My problem is that when I have multiple documents open, I don't know how to access the correct memo to save the contents to disk. My code is based on one of the MDI demos supplied with Delphi5, so the children...

I'm interested in using DLL's in Delphi 5 and being new to the whole DLL 'thing' I thought I'd follow a tutorial on actually creating one first, (which can be found at http://delphi.about.com/library/weekly/aa041100a.htm). The problem is that as soon as I compile the DLL, my AV software (AVG)...

I have an MDI app in Delphi 5 and through necessity have a TTabSet component on the parent form. When the first new child window is created a new 'Untitled' tab appears correctly with focus, but when subsequent child windows are created the named tab appears, but the first one retains focus. I...

I have Delphi 7 personal and I have to admit to being no expert when it comes to installing components. Those I have installed worked first time, but when one causes problems I'm stuck! I'm writing a simple text editor and was after a memo which allowed coloured lines and keywords. I was told...

I've just got Delphi 7 PE on a coverdisk and was wondering before I install it if anyone knows if it is possible to create apps with it which will run on my Pocket PC. I've searched the forum for the subject and could only find a similar question about a Palm. My PPC has an ARM processor and...

Hi I'm new to API calls, so please bear with me if this is a stupid question... I'm trying to get the screen resolution of the Windows desktop using gdi32.dll - function "GetDeviceCaps". (I've successfully used "GetSystemMetrics" in user32.dll, but that returns the current...

I have a form with a RichEdit on it and I simply want to remove blank lines from any text file loaded into it. I just can't figure out how to do this. There's no such thing as RichEdit1.Lines[N].Delete, and although the help files say that you need to use Strings[N].Delete, nothing I seem to do...
