problem adding reference

[shashank.aka.invi]

Hi someone plz help me. I have made a dll in VC++ .NET using following
specifications

extern "C"
{
__declspec(dllexport) void Probe_Interfaces_Local()
{
//some code
}
}

i compiled it successfully and add the dll formed to another C# project
directory. The c# code looks like this...

using System;
using System.Runtime.InteropServices;

namespace read
{
class Capture
{
[DllImport("mod2.dll")]
public static extern void Probe_Interfaces_Local();
//some code
}
}
The C# project compiles successfully but when i run it it breaks with
dll exception and says unable to load dll(mod2.dll)

I am not very familiar with C# syntax, but have you investigated the
error code ? Also, is it possible that some dependent DLLs of mod2.dll
are not present and the loadlib of the mod2.dll is failing.
just my 2 cents worth..

You must have the DLL in the path of the caller, that is the same directory
or in a directory which is in the path environment.
DllImport uses LoadLibrary to load the DLL, so the same search rules apply
here.

And in case the C++ DLL is compiled with /MD(d) and Visual C++
2005 you also need an embedded manifest to bind to the correct CRT
DLL. See the /MANIFESTDEPENDENCY linker switch.

Depends.exe, NT LDR (gflags.exe, "Show Loader Snaps" or _ShowSnaps
variable) are your friends.
