Storing and Retrieving Test Results
Using the To/From File Objects
Retrieving Data with the From File Object
To retrieve data using a From File object, you must know how the data
was stored.
Note You can also store and retrieve data using To DataSet or From DataSet,
which does not require you to know the type of data in the file. Datasets are
described in the section “Using DataSets to Store and Retrieve Records” on
page 232.
In this example, the name of a test is stored in a
String Format, followed
by a time stamp in
Time Stamp Format and an array of Real64 numbers.
You will create three transactions in
From File to read the data back into
VEE.
1. Select
I/O ⇒ From ⇒ File and place it below the To File object.
2. Connect the sequence output pin of the
To File object to the sequence
input pin of the
From File object.
This sequence connection ensures the
To File object has completed
sending data to
myFile before From File begins to extract data.
3. In the
From File object, leave the default data file myFile. Double-
click the transaction bar to get the
I/O Transaction dialog box. Click
REAL64 FORMAT and change it to STRING FORMAT, as shown in Figure
5-7.
