Hi, I hope someone can help? I am working with ‘Beginner’s corner: Using the sdk: learn to work with the software development kit’ in AUM31. I am using Microsoft Visual Studio.Net 2003.

I can build the first dll and get the following message:

Compiling…
Stdafx.cpp
first.cpp
Linking

Build log was saved at \\File://c:\MyDlls\first\Debug\Buildlog.htm

Build:1 Succeeded, 0 Failed, 0 Skipped

---------Done-------

Build: 1 Succeeded, 0 Failed, 0 Skipped

When I then modify the first.cpp file and add:

DLLFUNC fixed KillFile(long file)
{
fixed *temp = (fixed*)adll_getwdlobj("temp");
A4_STRING *my_file = (A4_STRING *)file;
return INT2FIX(remove (my_file -> chars));

I get the following message when I click on 'build':

------ Build started: Project: first, Configuration: Debug Win32 ------

Compiling...
first.cpp
c:\My Dlls\first\adll.h(14) : fatal error C1083: Cannot open include file: 'atypes.h': No such file or directory

Build log was saved at "file://c:\My Dlls\first\Debug\BuildLog.htm"
first - 1 error(s), 0 warning(s)


---------------------- Done ----------------------

Would anyone know how to overcome the problemn when using Microsoft Visual Studio.Net 2003?

Thanks in advance!

put the atypes.h file in your project directory

Hi

Thanks for your help. I have been away for some time but have returned to the problem. I now get the following error when I compile. Would you know if there is a simple reason for this?

Below is the code which I think is OK:

// first.cpp : Defines the entry point for the DLL application.


#include "stdafx.h"
#include "adll.h"
#include "afuncs.h"
#include <io.h>

BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
return TRUE;
}

DLLFUNC fixed KillFile(long file)
{
fixed *temp = (fixed *)adll_getwdlobj("temp");
A4_STRING *my_file = (A4_STRING *)file;
return INT2FIX(remove (my_file -> chars));

Code:

---

DLLFUNC var fixed KillFile(long file)
{
fixed *temp = (fixed *)adll_getwdlobj("temp");
STRING *my_file = (STRING *)file;
if(remove(my_file->chars))
{
return _VAR(1);
}
else
{
return _VAR(-1);
}
}

No idea if it works, but you could try it

I'm not sure what version of the engine you are using to test the dll; as an example, "temp" has disappeared from the current version of the engine. Anyway, reading the email I've got from you makes me think that you might have forgotten to link the .lib file to the project.

One more thing: the syntax has changed a lot since Aum31, so my ancient code will only run with the old sdk. The new sdk is much more user friendly.

Hi

I am still struggling with this but haven't given up. I tried the code above which did not help. I noticed when I click on 'T' I get the message 'Malfunction W1523 KillFile Not found in DLL'. When I then click 'OK' it incorrectly says 'The file was deleted successfully'. My questions are:

1. Does anyone know what 'Malfunction W1253' means?
2. Does anyone know how to check that I have linked the lib.file to the project?

Thanks for all the support received previously!

Three days later you probably have this solved already, but if you don't:
Remove fixed?
Code:

---

DLLFUNC var KillFile(long file) {
	STRING *my_file = (STRING *)file;
	if(remove(my_file->chars)) {
		return _VAR(1);
	} else {
		return _VAR(-1);
	}
}
	//fixed *temp = (fixed *)adll_getwdlobj("temp");
	// temp is a pointer to VECTOR structure with newer SDK?
	VECTOR* vTemp = (VECTOR*) engine_getobj("temp");
	if (vTemp == NULL) { return _VAR(0); }
	vTemp->x = _VAR(3.14f); 

---

Alternately, use the SDK packaged with 6.40.5 or 6.50.6 along with the applicable 3DGS version, and this should probably work:
Code:

---

DLLFUNC var KillFile(STRING* _sFile) {
	if (_sFile == NULL
	|| _sFile->chars == NULL
	|| strlen(_sFile->chars) < 1) { 
		return _VAR(0); 
	}
	return _VAR(remove(_sFile->chars));
}

// in C-Script
plugindir = ".";		// place the dll plugin in your project directory "."
							// or set this string to Visual C++ Directory
dllfunction KillFile(_sFile);

Hi

Thanks for the help. I have taken some time to get back to it.
When I try to build the DLL with the following code mentioned above:


#include "stdafx.h"
#define DLL_USE
#include "adll.h"

BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
engine_bind();
return TRUE;
}
DLLFUNC var KillFile(long file) {
STRING *my_file = (STRING *)file;
if(remove(my_file->chars)) {
return _VAR(1);
} else {
return _VAR(-1);
}
//fixed *temp = (fixed *)adll_getwdlobj("temp");
// temp is a pointer to VECTOR structure with newer SDK?
VECTOR* vTemp = (VECTOR*) engine_getobj("temp");
if (vTemp == NULL) { return _VAR(0); }
vTemp->x = _VAR(3.14f);
}

I get the following three errors.

c:\Projects\Last\Last.cpp(17): warning C4312: 'type cast' : conversion from 'long' to 'STRING *' of greater size
c:\Projects\Last\Last.cpp(18): error C3861: 'remove': identifier not found, even with argument-dependent lookup
c:\Projects\Last\Last.cpp(25): warning C4312: 'type cast' : conversion from 'long' to 'VECTOR *' of greater size

Would you have any advice on how to correct these? I found a good tutorial on the GameStudio site about creating a DLL in .Net which seems to have helped me as well.
