Hi.

I have a problem. I am trying to use LoadLibrary on a symatnec dll. It's exports are shown below but I don't know where to begin. I've used LoadLibrary before on standard DLL's but not classes.

Can anyone see any problems with using this DLL, could someone help me.

C++

private: __thiscall Func::Func(void)
private: __thiscall Func::~Func(void)

public: int __thiscall Func::Clear(void)
public: int __thiscall Func::Init(void)
public: static class Func* __cdecl Func::New(void)
public: unsigned long __thiscall Func::Function(void)
public: void __thiscall Func::Delete(void)
public: void __thiscall Func::Free(void)

Thank you very much.

I have never used this website before so please forgive me. I have just found the improve question button.

I am using VS2005 but I am looking to download Symantec C++ now, although it does look very out of date.

As Aesceal suggested, you should state the compiler you're using (C++ function name mangling is implementation-dependent).

Solution 1

This should help - Using classes exported from a DLL using LoadLibrary[^]

Solution 2

Why don't you go with the standard way of doing it then: load the dll implicitely by using its library file ? If the DLL exports classes, then it is clearly meant to be used with implicit loading.

Solution 4

Are you using Symantec's C++ compiler to call the functions you're manually loading?

If you're not then there's a world of hurt coming your way. It's not impossible but it's a complete pain in the bum.

Cheers,

Ash

Hi.

I'm not but my end motive is trying to figure out how they ZIP Compress a stream. Although it looks like a zip there is something else going on.

I'll keep trying, thanks for the advice.

I am not I am using VS2005. I will take a look into it thankyou. The end goal is trying to figure out how Symantec compresses its zip streams because although I know they are zip compression if I try compressing a stream a handful of different ways they never decompress successfully. So I am hoping the information the DLL might provide might help me with this quest. Thankyou.
