LoadCSV from a variable

[nsidney]

I would like to load CSV data from a webresponse variable into a ListBox, but I get the error "Object reference not set to an instance of the object." Is there a way around this?

Thanks

Response.Value = Request.GetResponse
result = Response.GetString
Response.Close
Eventlist.loadcsv(result, ",", false, true)

What is the tipe of the "Response" control?
Does the getresponse statements retrieve any result?

[nsidney]

the "result" is the result of a WebReponse function and data is actually returned successfully (I verified that with a msgBox that displays the value of "result").

thanks!

Wich you can read and populate the listbox...

Oops... didn't notice the difference there .

Ok so when I changed it into a Table control, it thinks "result" is the name of the file. How can I take "response" and feed that into a file and then send that file name to this LoadCSV function?

Thanks

Or... is there an easier way to loop through CSV data and add each row to the table (or a listbox)?

[Cableguy]

Were does the data came from? a file or from a web site?
If all the data cames in a simple string with a know separator you can use StrSplit

StrSplit Previous Top Next

--------------------------------------------------------------------------------
Splits a string and returns an array of strings.
Syntax: SrtSplit (RawString, Separators)
RawString - The string that will be split.
Separators - Zero or more characters that act as the separators.
If the Separators string is an empty string then all white characters will be used as the separators.
Example:
Sub Globals
dim words(0) as string
End Sub
Sub App_Start
sentence = "$GPGGA,161229.487,3723.2475,N,12158.3416,W,1,07,1 .0,9.0,M,,,,0000*18"
words() = StrSplit(sentence, ",")
for i = 0 to ArrayLen(words())-1
msgbox(words(i))
next
End Sub

Hi nsidney,

If the expected data amount in 'result' is small then please try this way:

Response.Value = Request.GetResponse
result = Response.GetString
Response.Close

FileOpen(c1,AppPath & "\interim.csv",cWrite)
FileWrite(c1,result)
FileClose(c1)

Table1.LoadCSV(AppPath & "\interim.csv", ",", false, true)

You can then populate a listbox or a combobox from the table with the
added advantage of having a backup file of the downloaded data.
