Prevent vi running when opened

[Miakatt]

Hi,

I have a vi in which I've made a mistake with the pointer allocation in to a Call Library Node block. When I tried to run the vi, LabView crashed. 

Now when I try to open the vi again, it immediately crashes with 'Exception: Access violation (0xC0000005) at EIP=0x01CA3B32. It isn't reaching the vi GUI window or the edit window.

Is there a way to prevent the vi from allocating memory when opening. I'm surprised it is even doing this considering the code isn't even running! 

Thanks in advance.

Not sure if this is what you need, but you can open a new VI and drop your problem VI onto its block diagram. Then you should be able to right click it and edit properties.

Hi Gregory,

Thanks for the suggestion. Unfortunately, the error I've introduced is in the master vi, which contains around 15 sub-vi's. I can drag any of the sub vi's to a blank vi and open as you suggest. But when I try to do this with my master vi, my laptop cannot handle it and LabView stops responding. 😞

I've installed an evaluation copy of LabView on my Macbook and can open the master vi. So at least I have a vi to copy from (by hand). So it looks like that's the quickest solution.  Now back to the original problem of trying to understand how to pass a pointer to a call library node and obtain the data from the buffer that the pointer points to..! 

Thanks for your help.
