Need Labview so search for dll's

[reza_sed]

Hi

I have 2 dll's with different names, both which work with Labview.  I eventually want to create an application that can be used by myself and say customers, however, I would like to have acces to one dll while the custmers have access to the other.  So basically I would like Labview to automatically search which DLL is available in a specified directory and use that one AND not ask the user "which dll to use" before running the application .  I need the dll's to have different names to differentiate between the two.  I have no idea how to go about this if anybody can help

Worse comes to Worst I will probably create 2 dll's with the same name in different directories and then copy and paste it to the directory Labview will be seraching but again I would like the dll's to have different names to easily differentiate between the 2.

Thanks

You could create two dynamically called sub-vis.  One for each dll.  Then call the one you need at runtime.

yeah, but I don't want to give the user the choice between or access to the 2 dll's.  Meaning if I packaged this on a cd I would include only the dll that they (the sutomers)would need and Labview, upon seeing which dll was available on the cd would then call the appropriate one.

Is that possible?

I can't remember if LabVIEW 8.0 had this feature, but LabVIEW 8.2 and 8.5 have the ability to specify the path for the DLL on the block diagram using an input terminal, rather than in the Call Library Node configuration dialog. So you could actually program the directory searching into your application. Your VI will find the appropriate DLL and use it.

[PJS]

and if you use the dynamic subvi approach, just include the subvi that calls the correct dll.

Jarrod, would you happen to have any examples or information on how to go about doing that......mainly what function allows you to specify the path for the DLL on the block diagram using an input terminal

Thanks

Drop the call library function, open the configuration panel, and there is a check box right under the library name or path that says "Specify path on diagram"
