If you want to download program updates from a web site, then this is the plug-in for you.
It shows the progress for the current file, and will let the user re-try any files that failed to download.
Good news everyone! I really am THAT good...

I haven't tried it with FTP (yet) - as I've mainly doing it for HTTP

No, I know how to do FTP. I didn't know how to do it in DBPro (No possible in native commands, right?).

I mean I didn't know how to get files from the internet, such as "http://www.darkbasicpro.com/apollo/images/avatars/loveme.gif". Say, if I try to load that image, it can't find it. With your plugin, you can load images/files like this, right? I already know how to do FTP nativly.

Yes, you can download any files - you specify the URL address (FTP wont work), the list of files you want to download and the place where the downloads are to be stored.

The files are then automatically downloaded - you can see how much is left to download for each file, and at the end a summary of the total number of successful and failed downloads is displayed. If there are any failed ones, you have the option of retrying the download.

It is designed to delete everything in the specified storage directory and re-build it during the download it process (so only the latest files are present). It is also designed to make sure there are no duplicate filenames.

I will be adding :

Before trying to download the first file, it will look for a MESSAGE.INF file. If this is present, then the file is downloaded, the contents displayed and the routine is exited. This lets you setup a 'There are no updates availiable at this time' system.

Next, I'll be a versioning system.

Probably because its not there - and wont be until I get my new computer...
If you want it when I've finished, it'll have to be sent through e-mail.

If you want a demo of the executable, I can e-mail it to you.

The test code is :



The 4 numbers are the version information for that file. It downloads some stuff from my web site - in the same directory structure as that.

Anyway, the format of various files are :

MESSAGE.INF - If this is present at the root of the web address, then the contents are downloaded, displayed and the update routine exists.

For versioning :

Each file needs to have a version that has .VRS at the end, which contains 4 groups of 3 numbers seperated by commas (eg 001,002,003,004). If this file exists then it is downloaded and the contents read. This version number is compared to that which corressponds to that which was passed to the routine. If the contents from the .VRS files is greater than that passed then the file is downloaded, otherwise it is ignored.

If no .VRS file is found then the file is downloaded.

EG :

Game.exe - The file to be downloaded
Game.exe.VRS - The version information file (its easier for me like this)

After being read, the .VRS file is deleted (so will never appear in the directory for updates).

By the way, the directory update will mirror that from the web site.

How you then apply the update(s) is then up to you...

I'll probably make it a lot friendlier to use soon.

Good news! I've found an efficient way of creating multiple directory paths, so it'll be compatiable with 98 upwards now.

Its working very well... at the moment...

Now, the important part is how to install any updates, especially if you want to upgrade the main program.

The main way I'm thinking of doing it is that the user will be requested to locate a file (executable, data file etc). This is because using the registry is a bad thing (and doing it this way should allow network upgrading). Once found, the full path is put into a .INI file, where the location can be read. The ideal way would be to use Clickteam's Install Maker (if you want to package everything in one file), as it can read .INI files for the destination location, and support delayed copying. This will be the default installation system in my plug-in.

Update : It appears that these installers wont read INI files if they dont have the full path to where they are (which is a bit stupid). So, I'm going to do the copying process inside the plug-in (it will copy everything to the destination location). Unfortunately this will mean network updates wont work (but no great loss).
