Hi.

I'm fairly new to VB.

And i was wondering.

Could anyone help me with splitting?

See i don't know the concept of the functions chr() etc..

For example:

If fso.FileExists(App.Path & "\DATA\OBJDATA.TXT") = False Then Exit Function
roomdescs = fso.OpenTextFile(App.Path & "\DATA\OBJDATA.TXT", ForReading).ReadAll
roomfurniname = Split(roomdescs, finame & "_name = ")(1)
roomfurniname = Split(roomfurniname, Chr(13))(0)
roomdescription = Split(roomdescs, finame & "_desc = ")(1)
roomdescription = Split(roomdescription, Chr(13))(0)
thex = Split(SData, " ")(2)
they = Split(SData, " ")(3)

This laods from a text file etc..

Could anyone explain what is happening in this type of code and explain abit more about packet splitting and chr() Etc?

Thanks.

Chr() returns a character code from the ASCII number given to it. 13 is the symbol for a new line, hence, you're splitting at every new line in that code.

However that will leave trailing break Chr(10) characters on each item as on windows the new line sequence is actually CR LF - you should use the constant vbNewLine instead which is a platform dependent constant.

Because, y'know, VB is used on so many platforms...

Mac is (barely) an operating system too. And I really meant .NET which runs on a multitude of architectures and platforms. Anyway it's better programming practice and more legible than a load of magic numbers.

Now that, I agree with.
