VB importing of DLL functions with build type conditionals
So I'm trying to import a function from a library I'm developing. I have "libraryD.dll" built for debugging and "library.dll" for release. Unfortunately, that means that I have to do this:
#If Debug
Declare Function someFunction Lib "library.dll" Alias "someFunc" () As Integer
#Else
Declare Function someFunct开发者_如何学编程ion Lib "libraryD.dll" Alias "someFunc" () As Integer
#EndIf
Now this would be fine but for ALL 40 functions this would make things very ugly to look at (and a tad bit unfriendly).I would like to do something more like this:
#If Debug
#Const dllName = "libraryD.dll"
#Else
#Const dllName = "library.dll"
#EndIf
Declare Function someFunction Lib dllName Alias "someFunc" () As Integer
Is there ANY way to do this in VB? :-(
TIA!
You simply do one thing...
Dim dllName as string
#If Debug
dllName = "libraryD.dll"
#Else
dllName = "library.dll"
Declare Function someFunction Lib dllName Alias "someFunc" () As Integer
This will certainly solve your problem...
Happy coding... :)
Try using the DLLImport attribute:
#If Debug
Const dllName = "libraryD.dll"
#Else
Const dllName = "library.dll"
#EndIf
<System.Runtime.InteropServices.DllImport(dllName)> Private Shared Function somefunction() As Integer
End Function
