Visual Basic - how do i save details from a form

utilitarian

Here is what i want to do, in Visual Basic 6, i am making a game... it is a kind of Sim City game where there are loads of numbers going up and down and all this kind of thing... i can do all that fine.

Problem is the following, lets say someone plays my game, but want to then save their progress and come back to it later, i need to be able to read their statistics from a data file of some sort...

I know i'm asking alot here, but how do i set up this file? How do i write details to, and read details to and from a form

thanks in advance

You could look into ini files, it's proberly better then a txt file for future proofing later versions of the program.
(some people might say use the registry, but I feel this affects portability of the program)

I've just done a quick google and come up with: http://www.officecomputertraining.com/vbtutorial/tutpages/page40.asp

You'll prob need to look through a few.

If its a sim-city type game I'd imagine there's a lot to save. Would you not write the detail to a database?

Look up any and all fo the following:

1) DAO, RDO, ADO, and other database-access techniques
2) Registry I/O
3) Ini-file I/O
4) File I/O

How do i write details to, and read details to and from a form

Same way as you read/write details from/to a form when you're not saving to file. If you've got your game working, you're almost definitely already reading from and writing to a form.

have a look at XML as well
might be handy

that is cool, however, what i want to know is what do i write... i will look into the things that you told me to but is there not some "write C:\MyFolder\data.dat" that i can do?

But

This might be useful for simple reading and writing to a .dat file or whatever you like.

Simple file I/O in VB:



'Writing to a file
dim iFreefile as integer
iFreeFile = freefile



Open "C:\test.txt" For Output As #iFreeFile
Print #iFreeFile, "This is the sample text"
Close #iFreeFile

'Reading from a file
dim iFreefile as integer
dim sInput as string
iFreeFile = freefile

Open "C:\test.txt" For Input As #iFreeFile
Line Input #iFreeFile , sInput
close #iFreeFile


Use For Output for creating new/overwriting file
Use For Append for creating new/adding to a file
Other options are also available but this should get you going
