current directory problem

[Neil.Pate]

Hi there.
How can I force LabVIEW to go to a specific directory on the hard-drive? I have a DLL function which loads some .exe files into a DSP, but if (for example) a different directory had been previously specified by the file dialog then the DLL function fails (to locate the .exe files). I have tried all sorts of combinations of getting the current vi path etc, running an arbitrary batch file in the directory i want etc. None of this seems to work. The DLL (which I cannot edit) looks in the same directory for the .exe files.

pls help!
thanks
neil

Are you passing a path to the DLL or is the DLL looking for files in the current directory? If you need to set the current directory, a call to SetCurrentDirectoryA in kernel32.dll might do the trick. I've attached an example in LabVIEW 7.0 to show what I mean. It has a path constant that you can set to whatever you want.

Dennis,

the DLL is looking in the current directory, but
using the kernel32 function worked perfectly! 🙂

thanks a lot!
