need a sample dll for generic plugin

[Unbeliever]

Hi, Im new to dll's and winamp plugins.

I was wondering if anyone has a sample gen_plugin dll which is completely empty and doesnt do anything, just has all the necessary methods needed for winamp to register it?

Im using VS.NET, but shouldnt make a difference.

This is the main hurdle Im facing. I know how to do the rest once I have the bare bones dll to work with

Cheers.

I'd like to get my hands on one of those also..I'm using a wrapper which isnt very efficient, but it works

This can be compiled with vc++ 6.0

Put the code in two files: gen_empty.h and gen_empty.c (not *.cpp)

//-----------------------
//gen_empty.h
//-----------------------
#ifndef gen_empty_h
#define gen_empty_h

typedef struct {
int version;
char *description;
int (*init)();
void (*config)();
void (*quit)();
HWND hwndParent;
HINSTANCE hDllInstance;
} winampGeneralPurposePlugin;

#define GPPHDR_VER 0x10

extern winampGeneralPurposePlugin *gen_plugins[256];
typedef winampGeneralPurposePlugin * (*winampGeneralPurposePluginGetter)();

#endif //gen_empty_h

//-----------------------
//gen_empty.c
//-----------------------
#include <windows.h>
#include "gen_empty.h"

int init(void);
void config(void);
void quit(void);
winampGeneralPurposePlugin plugin = {
GPPHDR_VER, //
"Empty (gen_empty.dll)",// Description
init, // Initialization function
config, // Configuration function
quit // Deinitialization function
};

int init()
{
MessageBox(plugin.hwndParent,"init","",MB_OK);
return 0;
}

void config()
{
MessageBox(plugin.hwndParent,"config","",MB_OK);
}

void quit()
{
MessageBox(plugin.hwndParent,"quit","",MB_OK);
}

__declspec( dllexport ) winampGeneralPurposePlugin * winampGetGeneralPurposePlugin()
{
return &plugin;
}

//-----------------

Ah.. could you convert this to C++?

What do you think this was written in???

My first post was written in C, not C++.

I use VC++ 6.0 - and I'm NOT AN EXPERT IN C++

I zipped the project as well :-)

I didn't find out myself - most of it has been posted before.

1. Make a new project : MFC AppWizard DLL, name it gen_test4 if you want to copy paste the code below.
2. Add the 2 header files to the project (frontend.h, gen.h) (gen.h is listed below - frontend.h: http://www.winamp.com/nsdn/winamp2x/dev/sdk/FRONTEND.H)


-- gen.h - start ---
typedef struct {
int version;
char *description;
int (*init)();
void (*config)();
void (*quit)();
HWND hwndParent;
HINSTANCE hDllInstance;
} winampGeneralPurposePlugin;

#define GPPHDR_VER 0x10

extern winampGeneralPurposePlugin *gen_plugins[256];
typedef winampGeneralPurposePlugin * (*winampGeneralPurposePluginGetter)();
-- gen.h - end ---

[bananskib]

and the project zipped !

forgot it :-)

Yes I have seen this before.. excellent work. it is not what I meant though. I was looking for a plugin written in C++ in the Win32 API, not MFC.

[peter]

C code should compile fine in CPP after adding a few typecast fixes and extern "C" on _declspec(dllexport) function.

[paulhemmings]

also like an example Win32 project

I've managed to build a general plug in using the MFC example gen_test4 but i'd also rather build one from a stripped down Win32 dll project as well.

i've downloaded the SDK, if anyone has a Win32 project which compiles using that SDK and could zip it up and put it on this thread, it'd be very cool.

remember - VB sucks.

[Gourou]

anyone got a template in VB (other than genwrapper, ick) for a plugin? I know it wont be by any means short enough to paste in here, but I would love to be able to turn all these programs I have into plugins.

[baafie]

For all of you who are as dumb as myself, here it is then

gen.h

code:


typedef struct {

	int version;

	char *description;

	int (*init)();

	void (*config)();

	void (*quit)();

	HWND hwndParent;

	HINSTANCE hDllInstance;

} winampGeneralPurposePlugin;



#define GPPHDR_VER 0x10



extern "C" winampGeneralPurposePlugin *gen_plugins[256];

typedef winampGeneralPurposePlugin * (*winampGeneralPurposePluginGetter)();

main.cpp

code:


#include <windows.h>

#include "gen.h"



#define PLUGINNAME "Empty plug-in v0.1"



BOOL APIENTRY _DllMainCRTStartup(HANDLE hMod, DWORD r, void *empty)

{

	return 1;

}



extern "C" winampGeneralPurposePlugin plugin;



int init() {return 0;}

void config() {}

void quit() {}



winampGeneralPurposePlugin plugin = {

	GPPHDR_VER,

	PLUGINNAME,

	init,

	config,

	quit,

	0

};



extern "C" __declspec( dllexport ) winampGeneralPurposePlugin * winampGetGeneralPurposePlugin()

{

	return &plugin;

}

I don't get your point, what you're writing is still C code.

[baafie]

Yes, but this way I can use C++ in my application, which is great for me because I suck at C.
