VB6: Reading from specific line in a txt file

[Einvalt]

My program keeps a text file list of co-ordinates, for example:

3,5
2,7
12,9
5,6
... and so on, indefinitely.

How do I read the values from the nth line into variables X,Y - say if I specific the 3rd line, then X=12 and Y=9?

Also, how can I search the text file to check if a specific co-ordinate pair is already in the list?

Hi there,

i would suggest you using .ini file instead .txt file.. ini files are more flexible..

you can make use of some simple API.. see below..

Sub WriteINIStringVirtual(Section, KeyName, Value, FileName)
  WriteINIString Section, KeyName, Value, _
    Server.MapPath(FileName)
End Sub
 
Function GetINIStringVirtual(Section, KeyName, Default, FileName)
  GetINIStringVirtual = GetINIString(Section, KeyName, Default, _
    Server.MapPath(FileName))
End Function 
 

usage..

WriteINIString "xxx"xxx", "xxx", "filename.ini"
