hi, I'm having a problem adding arrays.

I am using the double-click property, and after each double click I want to add up each new array which has just been opened from each file. How can I add each new array to the previous one after every double-click??

Well, the doubleclick property of listbox returns either -1 (of there was no doubleclick) or the index of the item clicked. You can use this value to select either a case in a case structure that does nothing, or one that processes the file (from which I assume you are getting the data for the array).

Hi Mike
thanks for your reply. I have the doubleclick property working but I want to know how to add each file I double click on into an array and add all these files up as I go along. I will attach my program so far if it can be of any use.....I'm really stuck on this one!!!

Your confusing how and when to use shift registers and locals...The logic should be as follows;

If new file has been double-clicked read the array from it and add it with the results from the previous addition. Wire the result to a shift register and use the left terminal of the shift register to get the previous result used in the addition...

Attached is a picture showing this.

You may also want to put the save case outside the double-clicked case so that you can save whenever you want and not just the next time you double-click(?)..
