Depending on the type of dll, try temporarily switching to the directory
containing the dll

sCur = CurDir
ChDir sPathToDll
' call dll
ChDir sCur

and don't put a path in the Declare

Need to use functions from an external dll. When I start up i do not know
in
advance the location for the dll but have to query registry to get the
full
path. If I then assign this path pluss the dll name to a string variable
fullPath and use this as follows

Declare Function someFnction Lib fullPath .......

I get an error stating that the Lib must be a constant string. Is it
possible to get around this somehow when I do not know the location of the
dll on beforehand and the dll path is not included in the Path setting?
