Hi,

I've been using Dark Data for the first time today and though I've mostly figured it out, I seem to be getting the odd crash. Yes it could easily be my code, but still...I'm just wondering what everyone else thinks is the best way of creating a database within DBPro?

I've only implemented a simple event logging system, mainly as it's the easiest DB in the game, but I'm just not 100% convinced it could handle the big stuff later on.

Thanks
Nick

I think the crash happen when you use file incription mode. set it to zero and no crash will happen. I don't know why never managed to encript the files with dark datam, although the example file is encripted.

It still crashes randomly. Not very often, but it has once. I'm starting to think about making my own database functions using the Matrix plugins, but along the same lines as Dark Data.

I thought this thread would get more response than this! I was hoping for someone to come up with some plugins I've not heard of too.

Not many people make Databases with DBPro, because it only takes about 5 minutes in VB. In DBPro you have to make the menus, and simple little things like that. Although it would take a bit longer though, it should be very easy to do. I don't think you have an option for random data though like VB. As far as I know, all of DBPro data is sequential. Another thing about DBPro is that dll addons are something that have evolved over the years. So it would be good if you did make some nice Database functions.

I'm not actually making a database program, it's a game, though my custom GUI system has almost everything Windows has, only created in DBPro . I'll be releasing some screenshots of this soon probably. I just need to get this DataBase thing sorted first.

When I say my own Database functions I don't mean I'm going to make my own plugin, I don't know C enough for that.

I'm sure that people are happy with functions anyway. I've never been a fan of drop down menus. If I was making a game that required a hidden menu, I would make it slide in from the side of the screen like curtains. If you made that function, I would have uses for it.

can you leave me your data code snipet. maybe I can help you.

the best way to create data base is create user defined types objects (UDT). remember that each object can have its own id number which can be accessed directly using random access files.

if your game is simple and you're not expecting too many players (10-30 players), then create a user defined type array, sort this array according to score and then save it to a file.

I think I'm going to use arrays with types loading and saving only when the game is saved. Saving them as memblocks. The main game database will be created by a seperate program, which will turn a CSV spreadsheet into a memblock, which the game will load. I've already replaced my database code.

@basjack- As much as I'd like to make this a multiplayer game, I'm sticking with the 1 player for now.

@Pincho Paxton- I've already made a drop down menu function, but it's rarely used in the game and doesn't animate yet. In the next week (give or take) I'm thinking of releasing some screenshots as I need some actual help with something none GUI or database related. I'm hoping my screenshots will convince someone to join me in making this!

@basjak I haven't done it yet, but I've found all the required commands to do it to a CSV file. Theres a few commands in the Matrix1 plugins that can handle CSV files. It's just a matter of reading the file and saving in the usual way. As I said I've not done it yet, so there isn't any code
