Hi All,

i know this question is somewhat duplicated however i have tried the solutions i have seen so far to no avail so i am looking to your for help.

I have an Unmanaged DLL (i do not have the source for the DLL only the DLL, LIB and Header file (C++). I have attempted to write a C++/CLR wrapper but i have no skills in C++ and really struggling.

The class has several entry points (but looking at the header file these functions are inside a class) but i am not sure how the CPP file is performing the function.

The documentation from the provider doesnt not show any thing regarding the construction of the class / functions or if anything needs doing before calling the functions directly.

This is the DllImport that i am trying to use to call teh InsertExclusion entry point but i keep getting the error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

VB
<DllImport("AGDGatewayInterface.dll", CallingConvention:=CallingConvention.Cdecl, EntryPoint:="?InsertExclusion@CAGDGatewayInterface@@QAE?AW4AGDClientError@@JPADJ00@Z")> _
Public Sub InsertExclusion(
                                    lExclusionType As Integer,
                                   <MarshalAs(UnmanagedType.LPStr)> ByRef szValue As String,
                                    lAppId As Integer,
                                   <MarshalAs(UnmanagedType.LPStr)> ByRef szStartDate As String,
                                   <MarshalAs(UnmanagedType.LPStr)> ByRef szEndate As String
                               )
End Sub

        Dim val1 As String, val2 As String, val3 As String, val4 As Long, val5 As Long
        val1 = "012345678910"
        val2 = "2016-06-08 00:00:00"
        val3 = "2016-06-08 23:59:59"
        val4 = 3
        val5 = 0

        Call InsertExclusion(val4, val1, val5, val2, val3)


My question is really is that i do not know where i am going wrong to try and call this function or how if i need to call the CAGDGatewayInterface Class and then call the function from within the class?

Please can someone help me create the wrapper or get the right DllImports right for this please?

What I have tried:

Writing a C++/CLR wrapper
Changing the DllImport CallingConvention
Several variations on pushing the strings through such as marshal.

Your are working in the wrong direction. The declaration is straitforward and not with "decorared names" and even so the data type declaration.

My tip is to write a C++ wrapper dll which calls the other dll. So you can separate the problems from marshalling and calling the dll.

But somebody else got already an answer to this question.

I have tried without the decorated names but only works with decorated calls but then i get the AccessViolation.

I have tried writing a wrapper for this DLL several times but C++ i do not know, i dont know the syntax, structure or how it is laid out. i dont know how to reference the class object or instantiate them (never used C++ before)

THis is why i tried with the marshalling but that doesnt work. do you know any services that i could supply this information to that could write it for me (even if its paid for) becuase ive spent over a week on this already and getting nowhere fast.
