I have a CVI 5.5.1 application that was working on a XP test station up
until a few days ago, until it started crashing at exactly the same
point during execution. I am trying to debug the app but I am
having problems with the 'Dig_In_Line' function that should be in a
Traditional NI-DAQ Library. When the project is compiled, an
error message is displayed with the "Dig_In_line@16 in files...." error
message. For some reason the library is not listed in the project
files and it is not in user library paths. This should be a
standard library - how do I find the library and reference it in my
project.
I am not really sure what happened with your system. As you stated
everything was working, so your code is probably functional. However,
something obviously happened that caused the change. It seems to be that
maybe a reference to a nidaq.dll is missing or something along those lines.
One thing I would recommend is try running one of the examples for a digital
line operation. You should be able to find them in a folder path similar
to this: C:\Program Files\National Instruments\NI-DAQ\Examples
Are the errors that you are getting related to a compilation issue or are
you actually getting back some errors stating that something is going wrong
when you are running the code? We will have to narrow the issue down and
find out more specifically what changed to make the working application no
longer functional. Once we have found what the root of the problem is we
can find a solution to fix it.
