Case Structure

[ctk]

Hi

  I have 10 case in a case structure and I need error handling for each case. From pic attach which method use less memory? case 1 or case 2? Thank.

Your guess ?

Actually my case has more than 60 case and the VI which contain this case structure file size almost 17MB. I wonder why the file size so large.

Now looking a way to reduce the size. Anyway I using case 2 method now.

Good ! So you don't need help 😉

o.. that mean case2 use less memory? Thank

I doubt that the way you have the errors wired up is contributing too much to a 17M VI.

It is much more likly you have large array constants on the diagram or you saved some graphs or arrays on the front panel with default values.  You can attach your VI for us to look at, but I would be surprised if the error wire changes effected it at all.

Evan is right. You can get some information about your vi memory allocation by right-clicking the vi icon at the top right, and choosing "VI properties" then selecting "Memory usage" from the menu ring button. If you have stored a large amount of data as default values, this will appear in the data field.
This being said, the solution n°2 is of course much better.

Hi Evan, I make the VI to a library file and zip it. Hope all subvi will be in.  

 I am still trying to modify this subvi to make it use less memory.

Hi chilly charly

I attach that memory pic.

Your case structure holds about 300 cases. And each case uses at least 50Kb. Guess what ? 50K x 300 = 15000Kb = 15 Mo
Since most of the cases look to be duplicates, a better program structure, with some carefull planning, would probably have saved 90% of memory space.
Apart rewritting your vi from scratch, I don't think there is something you could do now.
Too late.
Sorry.
