Not sure whether your problem is the same since it isn't too specific. I've seen different people ask me about this and i tell them to unregister C:\Windows\System32\scrrun.dll and register the COM DLL manually. This might not solve your problem. This helped me when i got that error but i can't assure it will get you your fix.

just add an .h files with:

Wiccaan i did exactly what you wrote but i'm still getting the error:
"Attempted to read or write protected memory. This is often an indication
that other memory is corrupt" it says build succeeded but when i tick my checkbox it says that error :s
do i need to #include the .def file in the dllmain by any chance?

btw i'm using the full visual studio 2008 not the express edition

Ok so you say it happens when you click a checkbox. Whats your checkbox code for when it's clicked?

[Stylo]

well it coded in c# so:

Well mind not "blurring" out the function names and params? Those are kind of important to the error at hand. You are attempting to access something that you do not have access to, which is causing the error.

With this being coded in C#, I'm not sure if you have to take extra measures when importing a C++ DLL or not. I don't code in C#.

oh sry i haven't thought it's that matter
but the function name is PostMessage
i'm trying to make a dll like PMX that hop over the hook to the function
using the PMX method so relate to the Function as PostMessage2(hwnd,msg,wparam,lparam);

omg i think i forgot something very stupid now it's working without any errors lol i forgot to call some procedure XD
thanks alot for your help <3 you guys
btw my function goes like this : __declspec(naked) and not (dllexport)
and there's no error so is that ok?

[atom0s]

__declspec(naked) is mostly used if it is injected, not called from an outside source.

I would suggest you don't use it unless you are using it to write code caves and such.

Instead your function should be exported using:

Inside your .h file that defines the function exports:

[Stylo]

i have 2 .h files and 3 .cpp files in the project
i think i screw it up a little bit XD.

my dll name is pmx2.dll
my function name is postmessage2.

i wrote in "targetver.h"

ok i deleted my .h files and .def file
after that my cpp file was compileable
then i added a new header file and called it myHeader.h
i wrote in it:
