CreateNamedPipe identifier not found? - Chickendipper - Mar 25, 2016

Code:
Code
#include "pch.h" //windows.h
#include <stdio.h>
#include <iostream>

using namespace std;

DWORD WINAPI hook(LPVOID lpParam);
BOOL startsWith(const char *needle, const char *haystack);
void externalCall(const char *called);

BOOL WINAPI APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        threadHandle = CreateThread(NULL, 0, hook, 0, 0, NULL);
        break;
    case DLL_THREAD_ATTACH: break;
    case DLL_THREAD_DETACH: break;
    case DLL_PROCESS_DETACH:
        //TerminateThread(threadHandle, 0);
        //CloseHandle(threadHandle);
        break;
    }
    return TRUE;
}

DWORD WINAPI hook(LPVOID lpParam) {
    HANDLE pipeHandle;
    char buffer[1024];
    DWORD dwRead;

    pipeHandle = CreateNamedPipe(TEXT("\\\\.\\pipe\\OmniBotPipe"), PIPE_ACCESS_DUPLEX | PIPE_TYPE_BYTE | PIPE_READMODE_BYTE, PIPE_WAIT, 1, (1024 * 16), (1024 * 16), NMPWAIT_USE_DEFAULT_WAIT, NULL);
    while (pipeHandle != NULL) {
        if (ConnectNamedPipe(pipeHandle, NULL) != FALSE) {
            while (ReadFile(pipeHandle, buffer, sizeof(buffer), &dwRead, NULL) != FALSE) {
                externalCall(buffer);
            }
        }
    }
    DisconnectNamedPipe(pipeHandle);
}

void externalCall(const char *called) {
    if (startsWith("char", called)) {
        //todo
    }
}

BOOL startsWith(const char *needle, const char *haystack) {
    return (strncmp(haystack, needle, strlen(needle)) == 0);
}

In short, it tells me that CreateNamedPipe, ConnectNamedPipe and DisconnectNamedPipe are not found even though they're in WinBase.h (which is included in Windows.h) - is there any reason for this?

You have to use either the ASCII or Unicode version of it, so either CreateNamedPipeW or CreateNamedPipeA.
Same for the other APIs

Same problem when trying to use W/A versions.

Are you using a non-standard build config? (whats up with the pch.h)

make sure you include windows.h in your project.

I literally just opened up VS2015, made a new Universal DLL and put in that code. I think pch is just a precompiled header which I already include windows.h in

It's in pch.h

Define it in your C/CPP file, there is nothing wrong with that and as a recommendation, I suggest you switch to VS2013. VS2015 is unstable and overloads the CPU on large projects.

Exact same code, switched to VS2013, and no errors. Amazing.

Thanks :D
