Dynamic vi not in memory in exe

Question

Hello,
I am using LV 2009 SP1.
I am trying to build a "Main.vi" into an exe, in which this Main.vi needs to dynamically call two vi "A.vi" and "B.vi" using call by reference node.
Therefore in the Build Specs/Source Files, I've put A.vi and B.vi into "always included" before building the exe.
I assume this way A.vi and B.vi will be in memory already inside the exe and I can simply wire string constants "A.vi" and "B.vi" to the Open VI reference's vi path input, instead of loading the VI from the hard drive.
Unfortunately the loading from memory - string input approach gets me an error message and told me to provide a path to the input to load this VI into memory.
It kind of suggests that A.vi and B.vi is not in memory at all even though I've put them inside "always included" during the Build exe setup.
I would really want to get the string constant path input working instead of loading these VIs through the hard drive. Based on the above description, I would like to seek some help and determine what can I do to get it working.
Any help will be deeply appreciated.
Cheers
Will

Hi,
Mike is right with what he explained.  I just wanted to add, that if you're using paths (to the dynamic VI's) that you should be carefull with those.  The path to a VI in development mode is different then in runtime mode.
Development : ../Folder/VI
Runtime : ../Application.exe/VI
So you will have to check whether you are in development or in runtime.  More info on how to do that can be found here .  You can compare the output of this property to a certain value and determine which kind it is.
When you use the modern 2009 and newer application layout (the default unless selecting the 8.x layout in the build options), the path is actually the same in an executable than in the development system, at least in respect to the project file.
Another point: If the OP expects the VIs to be in memory anyhow why not include them as static VI reference? Or call them as simple subVI anyhow?
