Edgard,
In reviewing your problem again I noticed that you are using the SPLIT
command in your sample function to parse the WinSock data. That
implies you are dealing with a string and not bytes, integers, longs, etc.
Your line,
ArrayA = SPLIT(dataFromWinsock,'|')
makes ArrayA a string variable and not an array (but you could create
an array of strings). Since it's a string variable you can make a copy
of the data by simply assigning it to another variable, which then
becomes a string variable. You could think of a String variable as a
buffer for ASCII data.
For example:
Dim String1, String2
String1 = "my winsock data"
String2 = String1 ' copy the data
String1 = "" ' Clear the first string
Here an example of creating an array of string variables:
Dim Strings(4) ' Create an array to store 4 strings
Strings(0) = "my winsock data"
Strings(1) = Strings(0) ' copy the data
Strings(0) = "" ' Clear the first string
The above examples will NOT work with array of bytes, integers, longs,
etc. (The SPLIT command only works with string data.) The type of data
that you are dealing with determines how you have to handle the data.
If you are calling an external API with a byte or integer array, you
will get back an array that contains data that you can only access
using an array index.
To address Bob's comments, I think your example assumes you have data
available to store into the two arrays while it's being received. My
assumption was a WinSock API was called and an array returned
containing the data and that is what was needed to be transferred or
duplicated to another array.
As a side note, all my work with Declare/API calls dealing with
variables and arrays is with NS Basic Desktop, but I'm assuming it
also applies to CE too. Can anyone let me know if this is the correct
assumption?
Regards,
Tom
