How to read serial port and substring

Question

I am new for labview .I send data from microcontroller with C languange every 1 minute this codeprintf("T%3.2f,H%3.2f",fTemp_true,fRh_true);
And I read data with Hyperterminal it show this T29.11,H67.88 I want to show 29.11 and 67.88 only and stroe in database. I study connect serial port in example and I have a question. If I use this code.Can I auto read every 1 minute or this code can read 1 time only and I have to click every 1 minute.How to auto read when I send data to serial port with microcontroller every 1 minute. And I cannot substring 29.11 and 67.88 because %3.2f can show T29.11,H67.88 or T129.11,H100 . and  How can I simple send data to database. Thank you .

No, you don't have to click run every minute. You just need to place a while loop around the VISA Read. You could use Wait (ms) but it would be better to use something like the Elapsed Time function and wire the time has elapsed output to a case statement with the VISA Read inside the true case.
This is one way to parse the string:
If you have the database connectivity toolkit, you can easily write to a database. There is also something called LabSQL.
