hello all,

I am making a dll for dbpro and i am getting confused here.
When I excute my commands in dbpro I get a failed to write error :S

Here is the function I am using:

+ Code Snippet

MYCOMMAND void TESTP( void )
{
// Use Core PRINT to display output
 g_pGlob->PrintStringFunction( "HELLO WORLD", true );

}

And here is the string table:

+ Code Snippet

HW%0%?TESTP@@YAXXZ

It knows the function is there becuase it compiled. Then I i got the error.

Many Thanks, Edday

first of all have you got the core pointer - via adding the 3 extra functions?

if you have then define my command as extern "C" __declspec(dllexport)

and change you string table to Test%0%TESTP%void

and try it again

That still does not work, Here is my hole source code now:

+ Code Snippet

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

#include "stdafx.h"
#include "globstruct.h"
 GlobStruct* g_pGlob = NULL;

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

#define MYCOMMAND __declspec ( dllexport )


MYCOMMAND void TESTP( void )
{
// Use Core PRINT to display output
 g_pGlob->PrintStringFunction( "HELLO WORLD", true );

}

EDIT: It says here it cannot be found in dbpcore.

try this instead

+ Code Snippet

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

#include "stdafx.h"
#include "globstruct.h"
 GlobStruct* g_pGlob = NULL;

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

#define MYCOMMAND __declspec ( dllexport )

 MYCOMMAND void ReceiveCoreDataPtr ( LPVOID pCore )
 {
	// Get Core Data Pointer here
	g_pGlob = (GlobStruct*)pCore;
 }

MYCOMMAND void TESTP( void )
{
// Use Core PRINT to display output
 g_pGlob->PrintStringFunction( "HELLO WORLD", true );

}

the problem is is that you are using the core data pointer, but you have not recieved it
