Hi!

Is there a way to implement MathCad Prime Advanced Controls to execute WRITEPRN function on button press using Version 10 Advanced Controls? This is so that WRITE or APPEND will only be performed upon the user clicking on the button.

Thanks!

This is a great question.

Currently disable the WRITEPRN statement and enable it when needed to write the file.

Would welcome a solution like you suggest.

Cheers

Try this workaround:

First setup your output file by writing a "1" in the same file (using nested matrices) or in a separate file.
Now in your calculation document, before your control button, read the value of the number and feed that as an input into your control button.
In your control button, when the button is pressed, output the number+1, otherwise output a zero.
At the point you want to save your data, compare this number with the number in the file. If the new number is higher, then save the data, along with the new number.

@ttokoro made a good point . Here is my version using the date+time, down the the second. This is in VBScript but I am sure there is an equivalent in Java.
