DBP says "Parameter for 'XSDKMESSAGEBOX_OK' do not match Message$,Title$ at line 1."

DPB Call:

returnval = XSDKMESSAGEBOX_OK ("Test Message", "Test Title")

C++ Code:

// MESSAGE BOX OK ////////////////////////////////////////////
EXPORT int XSDKMESSAGEBOX_OK(LPSTR smessage, LPSTR stitle)
{
	int ireturnval=0;

	if(smessage[0]!='\0')

		 if (MessageBox(NULL,smessage,stitle,MB_OK) == IDOK)
		 {
			ireturnval = 0;

	else if(smessage[0]=='\0')
	{
		 MessageBox(NULL, "Error Code MBO162: \"LPSTR smessage\" is invalid.",

			ireturnval = 1;
	}

	return (int) ireturnval;

}

XSDKPUSHBUTTON%SLLLLLL%?XSDKPUSHBUTTON@@YAHPADHHHHH@Z% Text$, Xpos, Ypox, Width, Height, ID

probably your version of C..

alternatively you can export like

+ Code Snippet

extern "C"
{
  Function int xsdkMessageBox(string, string);
};

also you've got to make sure to set these definitions first.

If you want to return a value, that return value comes first in the stirng table.

Put:

+ Code Snippet

extern "C"
{
EXPORT int XSDKPUSHBUTTON(LPSTR stext, int ixpos, int iypos, int iheight, int iwidth , int ibid);
}

before the function declaration. Then for string table:

+ Code Snippet

XSK Push Button[%LSLLLLL%xskPushButton%String Text, Integer X, Integer Y, Integer Height, Integer Width, Integer ID

(err... that's exatly what Ravn put

oops

So whole VC6 code is

+ Code Snippet

#include "stdafx.h"

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

#ifndef EXPORT
#define EXPORT __declspec( dllexport ) extern "C"
#else
#define EXPORT __declspec( dllimport ) extern "C"
#endif

// Export the functions
extern "C"
{
EXPORT int XSDKPUSHBUTTON(LPSTR stext, int ixpos, int iypos, int iheight, int iwidth , int ibid);
}

int XSDKPUSHBUTTON(LPSTR stext, int ixpos, int iypos, int iheight, int iwidth , int ibid)
{

	CreateWindowEx(NULL,
					"button",
					stext,
					WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
					ixpos, iypos,
					iwidth, iheight,
					NULL,
					(HMENU) (ibid),
					NULL,
					NULL);

	return(0);
}

=/ i dont know why this is not working.

DB Source:

+ Code Snippet

 XSDKPUSHBUTTON "TEST",50,40,30,20,100

DLL Source:

+ Code Snippet

#include "stdafx.h"

BOOL APIENTRY DllMain( HANDLE hModule, 
                       DWORD  ul_reason_for_call,

					 )
{
    return TRUE;
}

#ifndef EXPORT
#define EXPORT __declspec( dllexport ) extern "C"
#else
#define EXPORT __declspec( dllimport ) extern "C"
#endif

extern "C"
{
EXPORT void XSDKPUSHBUTTON(LPSTR stext, int ixpos, int iypos, int iheight, int iwidth , int ibid);
}

void XSDKPUSHBUTTON(LPSTR stext, int ixpos, int iypos, int iheight, int iwidth , int ibid)

					WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON,
					ixpos, iypos,
					iwidth, iheight,

					NULL,
					NULL);
}

String Table:

+ Code Snippet

XSDKPUSHBUTTON%SLLLLL%XSDKPUSHBUTTON%String Text, Integer X, Integer Y, Integer Height, Integer Width, Integer ID

It keeps saying it cannot find XSDKPUHBUTTON in dbprocore.dll

No because he's EXTERN "C"ed.

I can't honestly see what's causing it. Make sure the plugin is in plugins-user and there's NO version of your plugin dll in the same directory as the EXE you're trying to run.
