Hi Sebb,
Sounds promising.
I did some testing, but without luck.
What I do is the following:
In my user parameters I add one line with the variable name (rows) and
the __csvread to my csv file. The first column has the row count. So my
syntax is: ${__CSVRead(c:\temp\migration.csv,0)}
Secondly I use the variable in the Thread Group window.
Number of Threads: ${rows}
Ramp-up period: 50
My script doesn't work anymore now. No result. Will stop directly.
In the log I see the following:
2005/06/02 10:18:34 INFO - jmeter.functions.FileWrapper: Attaching
c:\temp\Migratie.csv
2005/06/02 10:18:34 INFO - jmeter.functions.FileWrapper: Opening

2005/06/02 10:18:34 INFO - jmeter.engine.StandardJMeterEngine: Starting
0 threads for group ADSL. Ramp up = 50.
The version of JMeter I am using is: 20050508 (internal version)
Any ideas?

Subject: Re: Variable use in 'number of threads'?
It's certainly possible to use a property to specify the number of
threads.
So functions work, i.e. CSVRead will work.
The count should be placed in the first row of the CSV file.
Try the following (tested):
${__CSVRead(test.txt,0)}${__CSVRead(test.txt,next)}
Should also work for the ramp-up loop count if needed (not tested).
There is no guarantee that fields will be read in the same order in
each release, so all the values must be columns in the first row.
And you will either need to experiment to find which field should have
the "next" in it, or put it as the first entry in the UP
Pre-Processor.
The rest of the file can then be read in a User Parameters (UP)
Pre-processor or in samplers etc.
But it may be simpler to pass in the thread group settings as
properties, so you can use the same test file for different
variations, e.g.
1 thread, 10 loops
2 threads 5 loops
etc

for my test cases. In this way I have to set the number of threads to
the number of rows in my excel sheet. No problem, but it would be nice
if this is filled automatically. Just to follow the excel sheet, even if
there are test cases (rows) added or deleted. The way I am thinking is
the following: I count the rows in the excel sheet (excel function
COUNT). Place the number of rows somewhere in the sheet, read this value
with function __CSVRead (e.g. rows) and use this value to notify the
number of threads (${rows}).
