VB.NET app calling C++ dll, DLLNotFoundException
Posted on 2008-11-17
I have here C++ dlls that has been compiled as a 32bit dll.
It is called by .NET windows service, compiled as 32bit as well.
Provided below is a sample code to to use the methods of the C++dll
<DllImport("mytest.dll") , entrypoint:="mytestmethod1")>
public shared function mytestmethod1() as string
This works in 32 bit.
My problem is this - to make same code run in 64bit.
The C++ dll and the .NET windows service are now compiled as 64bit.
When i start to run the .NET windows service, I get an error as soon as I hit a code calling the C++ method - a DllNotFoundException exception. so nonetheless, i added try catch statements for DllNotFoundException.
Im still getting this error but Im dead sure i have the c++ dll in the .NET windows service bin directory.
