Just looking for some help/ideas

Most likely yes, given it's one of the fastest applications to run anything side by side with. And thats actually not bad, I tried to update the prices given enough change in the game, like for say if 1 or 2 items change not a big deal, but if a category drops in prices then yes. I'll look into that idea. Thank you.

I don't think you can do any networking in batch though. Maybe try learning C#/C++/Whatever?

I was actually thinking of combining the two. Like have the basics run on batch, which very little networking is possible, and anything that might need the network on C++.

Trying to keep its speed and compatability

Not sure why people obsess over speed for applications that don't require a lot of processing power to begin with. Maybe if the user is stuck using hardware from the 90's, one would notice a difference. However, with modern hardware, one would notice little difference in speed between something like flash and c++ for applications such as these. Btw in terms of raw speed, I can't see how batch would be ideal. C++, c#, Java would likely be able to do the job faster. Also why worry about internet connection when anyone using the app has an internet connection fast enough to throw a few bytes around?

I do not entirely understand the topic here. You want ideas for something to do with a price database?

I'm looking for possible add-ons/features, or just simple upgrade ideas.

Which is originally why I wrote it in batch, my pc is an older dell thats extremely slow, and i dont have the money to upgrade. I wrote it for personal use then posted it here to see what others thought. Plus, i have 4 other people that take up my bandwith with laptops and phones. Family..... So speed and simplicity is high priority. If it doesnt work fast on my pc then i cant use it, so i avoid the internet to avoid interruption of the game, and batch is more of a safe fail writing, it goes line by line not neccessarily jumping around according to certain parameters, preventing most errors. Aside from actual textual errors.

You ever try writing a price guide that uses the internet to get its prices and compare the internet based one with the one that doesn't connect to the internet? If you are able to play rotmg on the same computer, it has the hardware/internet connection to handle something like an internet based price guide easily.

Aside from all that, a internet connection isn't really necessary for such a program since you maintain it but this makes the batch script much less useful for anyone else.

I agree that batch is definitely not the way to go. If you are writing a program that displays pricing of items, it may be beneficial to have an XML file hosted somewhere that can hold all the item information, and have your application read the XML file. Thereby eliminating the need for users to update their application over and over.
