Here, Things you did not do...:

1.) Have globalStruct.h in the same folder...
2.) Did not set Direct X sdk root/include as a include directory
3.) Needed to change g_pGlob->hwnd to , g_pGlob->hWnd ( My bad )

---- Files ----
Attached - >>>>

(edit: Oh yeah.. Goto Project Options and Change the include to your DX root )

I decided to put globstruct.h in my include directory so that I wouldn't have to copy it to all my progects. Anyway thanks Eddie B you were a great help. I could kill myself for not seeing that W uncapitalized (Still too used to BASIC where caps don't matter).

It compiled good I am just having a little trouble fining the decorated name in the dll, I can find it in my other dlls. Is there some other way to get it other than by looking at the dll in notepad?

Meh, I dont bother with them, I just do:

What you want it to be called via%LLS%functionname
^^^ - Only an example - ^^

L=int
S=String

and if it returns a value , To be called[%LS or what ever%functionname

That is what I do but you still need the decorated function name. I can usually find it in notepad but now the name I find and use in the stringtable doesn't work. If it helps this is the name I keep finding _clswndw. I know it should be _Z4clswndwv but that doesn't work either

So I just have to add a def file right? When I make my stringtable do I use _clswndw or _Z4clswndwv ? (I found _clswndw in notepad)

I made a def file called Progect1.def, Inside I typed
, I opened up DevC++, opened progect options, used the Parameters tab, under Linker I typed -Progect1.def, I typed Closew%0%mynickname as my stringtable, and in DBP I typed Closew. What is wrong?

hmmm
hmmmmmmmmmmmmmm hmmmmmmmmmmmmmmmmm
what is the error(exactly)
if it says closew isnt found then make sure u copied it to plugins-user and also another thing u should try is try CLOSEW in your stringtable as i think everything must be capitalized except for your c/c++ function name(C/C++ is case sensitive also so check that)

I tried what you said and still got the same error. The error being that it can't find mynickname. (I can't find mynickname in notepad which leads me to believe that Dev isn't compiling the def file for some reason)

I figured out part of the problem in the linker box I typed -Progect1.def when I should have typed --def Progect1.def . My DevC++ compiler now gives me this error
. So do you know what is wrong?

I checked my stringtable, it is fine. This error is coming from my C++ compiler not my dbp compiler though.

It doesn't make sense to me either since my function recieves and returns void. Can anybody else make sense of it? Here is my whole progect if it helps.(Something wierd to look at is the first time you compile, it gives you a different error than the second time.)

to start this
#include <globstruct.h>
should be
#include "globstruct.h"

COMMAND void ReceiveCoreDataPtr (LPVOID _Core)
{

g_pGlob=(GlobStruct*)_Core;
Core = GetModuleHandle("DBProCore.dll");

}

i dont have that in my code and it works fine, i think it might be declared in globstruct.h

extern "C" {
try not using that and see what it does

COMMAND void clswndw( void )

is command defined in globstruct?

thats all i can see that could possibly be wrong

I have globstruct in my include directory so it globsruct has to have the <>. You can't take out the recievecoredataptr function (I tried). Taking out extern "C" { does nothing.

hmmm seems i commented that out oops u do need recievecoredataptr
try this source code/project if this code dont compile then try reinstalling or updating devc++ if there is anything new out

btw
this contains dbpstring function so u can instead of doing tons of compilicated junk to return a string u can just say return dbpstring("hello world!");

All the fuctions in that dll worked, but when I used my function I got the same error. I have now figured out the only thing wrong is the decorated function name in the def file, how am I suppose to get it?

open it in notepadand look, it should have a _Z(number) at the first
edit:
wait!
if u use extern "c" then use the unmangled function name

so now it works since u use extern "c" and the unmangled function name

extern C uses the C dll export method rather than c++ and C dont have mangled names
