Copying files from one to other location.. How to check status in run mode on front panel?

[Naqqash]

Hi guys , can anyone tel me that how can I check the copying status in real time while VI is running.. e.g lets say I am coping files from location A to location B and the data is quite large so if somewhere in between there is an error I can not figure out when the problem occurred. Is this possible that I know while staying on the front panel about the amount of data copied and how much is left etc..because I think it will be easy to track error if there will be any..

Hi,

It`s not possible with the function copy file of LabVIEW. But has two solutions, the first solution is: open the source file, read the contents in blocks and then write to destination file. The second is making API calls to SO. I take the second, in my opinion. See the function SHFileOperation which shows standard windows progress bar.

Thanks for the help. But I am afraid I didn't get the idea. Can you explain more or suggest me some link or can share some example vi. I'll be thankful.

Regards,

Naqqash.

Hi,

I tried to do it, but from some reason I failed. Here are some links about function and how to do it:

In the attachment is what I've been trying for the last half an hour. I did it before, but never using cluster -> structure casting.

If the problem you are having is calling a structure, there is a an example vi called Call DLL.vi in the example finder.  This post also might give you some more insight into this issue.
