Dear forum members. I have one question about labview basic.

Can you help me?

Thanks in advise.

Hi Melikyan,

again you posted the (nearly) same question in atleast two threads! Make ONE new thread for a new question or stick with the old, when the topic didn't change...

The question here is really basic:
There's a subarray-function. Wire the table to this function and supply the correct row/column/length values.

To do the same with an Excel sheet isn't basic. Here you should study the examples that come with LabView!

Dear forum members. I attach the Vi. Can you help me to show the way how to seperate for example the 5th cloumn and elements from 10 to 20.

Thanks in advise.

Sincerely

There is no table in this VI. Nor is there anything related to Excel as your other posting asks about. The only thing in this VI is a simple string returned by a VISA Read. If this string is something you need to parse out and need help doing so, you HAVE to include that string. Not only are you doing multiple posts of the same question, you are doing multiple posts without providing the necessary information.

To do this right, run the VI so that there is data visible in your string indicator. Go to your edit menu and select Make Current Values Default. Save the VI. Attach the VI you just saved.

Excuse me. Now I attach the file with Current Values Default...

Okay, so you are creating the array correctly. As already mentioned, there are several functions on the array palette that you can use. If you just want a certain rows in a single column, you can first use the Index Array function to extract one column. You do that by wiring a number to just the column input. Then, you can use the Array Subset function to get a specified number of elements from there.

To become familiar with how the array functions work, you can do the following. On the front panel of the VI with the large array, copy the array and paste it onto a new VI's front panel. Right click on the array and select Change to Control. The on the diagram, you can wire the array to various functions. Experiment with controls connected/disconnected to the inputs of the array function you have. With a front panel indicator wired to the function's output, you can see for yourself how the functions behave.
