Having some problems!
I?ve created a program where i write data as strings to a dat-file, and now i want to make a search-function or a sub. I want to be able to search for a specific string and have the program returning all the saved data for that string.
Is there anyone who can help me? | 2. Re: Problem searching datfile #962 | | Use QFileStream to read file into memory, then InStr to search: http://g.yi.org/_scripts/file.php?f=2492&r=2330 | 3. Re: Problem searching datfile #963 Posted by: 2003-05-22 17:10:05 | Hi Batteryman,
You could make an UDT with all the programs settings etc... and write/read the UDT to/from your file. Use the file.writeUDT and file.readUDT methods.
Or...
You could make a dat-file like this:
<parameter name1> = <data1>
<parameter name2> = <data2>
...and read it with a sub like this:
while file.position < file.size
content = file.readline
select case field$(content, "=", 1)
case <parameter name1> : data1 = field$(content, "=", 2)
case <parameter name2> : data2 = field$(content, "=", 2)
end select
wend
Kind regards,
Alain
