I'm using Microsoft Visual C++ Express 2012. I have the following as part of my header setup:
#include <windows.h>
#include <Ole2.h>
When I include windows.h on it's own there's no build errors, but when I include Ole2.h either with windows.h or without windows.h I get the following compiler error:
Error 1 error C2628: '_RPC_ASYNC_NOTIFICATION_INFO::$UnnamedClass$0x1c06c483$29$' followed by 'int' is illegal (did you forget a ';'?) C:\Program Files (x86)\Windows Kits\8.0\Include\shared\rpcasync.h 127 1 Test`
Any ideas what might be going wrong? Ultimately I'm trying to write some simple code to interface with Kinect, but even without any Kinect includes present the above error is still generated.
When I double click the error I am taken to rpcasync.h and the following code:
#if !defined(RPC_NO_WINDOWS_H)
//
// Notification by window message
//
struct {
HWND hWnd;
UINT Msg;
} HWND; //<<<-------- the error points here (HWND is underlined in red)
#endif // RPC_NO_WINDOWS_H
PS The reason I'm including Ole2.h at all is because I'm following this tutorial.

I'm trying to write a simple program to display shapes using 3dCoin
however when starting to debug the program it gives me 51 errors in cmath file in which I did not change anything in it since it is a standard file.
#include <Inventor/Win/SoWin.h>
#include <Inventor/Win/viewers/SoWinExaminerViewer.h>
#include <Inventor/nodes/SoSeparator.h>
#include <vector>// when I include vector it gives me the errors
int main(int, char ** argv) {
HWND window = SoWin::init("0.off");
if (window == NULL) exit(1);
SoSeparator * root = new SoSeparator;
root->ref();
SoWinExaminerViewer *viewer = new SoWinExaminerViewer(window);
viewer->setSize(SbVec2s(640, 480));
viewer->setSceneGraph(root);
viewer->show();
SoWin::show(window);
SoWin::mainLoop();
delete viewer;
root->unref();
return 0;
}
The type of errors I'm getting are:
Severity Code Description Project File Line Suppression State
Error C2589 '(': illegal token on right side of '::' project c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.10.25017\include\cmath 19

and many more.....
Can anyone help find the reason I have been trying to find a solution for a while but could not understand the reason behind such errors?
I've received exactly the same error with you. More than 30 lines of cmath and also int8_t type redefinition error. I've solved this problem by putting each of my header files above Inventors and then I've put #define HAVE_INT8_T above everything in my source files due to the int8_t type redefinition error. Then, compile error is gone.
I have written a callback method and when I am trying to compile the project in vs2012, I am getting the following error:
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C2143: syntax error : missing ',' before '&'
the both error present in same line.
These are the following code which I am trying:
#include <windows.h>
#include "atlstr.h"
///////////////////////////////////////////////////////////////////////////////
class CInf;
typedef BOOL (*PENUMDEVCALLBACK)(CInf* inf, const CString& devname, const CString& instsecname, const CStringArray& devid, PVOID context, DWORD& code);
I think the error will be present in CStringArray& argument because when I include the afxcoll.h.
the fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>.
When I removed the windows.h. the above error gone but I need windows.h header also.
Any idea how to include windows.h and afxcoll.h in same file.
It is not possible to include only isolated parts of the MFC. When you want to use CStringArray you Need to include the afx.h or afxwin.h file.
It is possible to use CString alone. If you just want an Array of CString and you don't Need the complete MFC than it is easier to use std::vector. CString works perfect with all STL container.
I am trying to use mciSendString in visual studio express 2013 (Visual C++) but I keep getting an error
Error 1 error C3861: 'mciSendStringA': identifier not found
I assume this i because I have not linked to the correct dll, but I cannot find any details online or on msdn about how to link to the dll. It seems quite strange that there wouldn't be more obvious documentation about this. Can someone tell me how to link to the dll?
EDIT:
Here is the code I am trying to run:
#include <Windows.h>
#include <iostream>
#include <mmsystem.h>
extern char command1[] = "open C:\\boing.mp3 type MPEGVideo alias 0";
extern char command2[] = "play 0 from 0";
int main()
{
mciSendStringA(command1, NULL, 0, 0);
mciSendStringA(command2, NULL, 0, 0);
}
To make mciSendString() to work, you need to link to winmm.lib.
Just adding winmm.lib to Project Properties > Linker > Input > Additional Dependencies will be fine.
Looking at mmsystem.h (admittedly from the V7.1A Windows SDK, which is the most recent I have installed), I can see that there's a #ifdef _WIN32 block in there. If _WIN32 is not defined, then mciSendStringA is not declared. Instead mciSendString is declared.
Check your project options and ensure that both WIN32 and _WIN32 are defined. I'm guessing that you started from a console project, rather than a Windows Application project, and that at least one of those isn't defined.
I have been trying to get GTK 3.0 to work, and have followed all the steps here
How to configure gtk on Visual studio 2010
And changing to 3.0 where needed to get GTK to work, and it seems to have loaded everything it needs in order to compile, but it gives me the error
Error 3 error LNK1104: cannot open file 'gtk-3.lib'
Whenever I try to run the program.
I am using visual studios 2012, but this was the only place i found anything about getting GTK to run on any visual studios.
Here is the code I am using:
#include <gtk-3.0\gtk\gtk.h>
int main(int argc, char* argv[])
{
gtk_init(&argc, &argv);
GtkWidget* window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
//gtk_widget_get_preferred_size(window, 300, 200);
g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_window_set_title(GTK_WINDOW(window), "GTK+ with VS2010");
gtk_widget_show(window);
gtk_main();
return 0;
}
I commented out the gtk_widget_get_prefered_size call because it is irrelevant to the problem
any suggestions? I've looked in several places but none came up with clear answers.
The library gtk-3.lib does not exist. In fact, the library reference is not required to build your GTK 3 application. The pkg-config helper doesn't seem to generate the correct linker flags needed to link your application.
Just add in your Additional Options area all the existing libraries found in your GTK package (\gtk3\lib). The lib files for my bundle (gtk+-bundle_3.6.4-20130921) were as follows:
atk-1.0.lib cairo.lib fontconfig.lib gailutil.lib gdk-win32-3.0.lib gdk_pixbuf-2.0.lib gio-2.0.lib glib-2.0.lib gmodule-2.0.lib gobject-2.0.lib gthread-2.0.lib gtk-win32-3.0.lib pango-1.0.lib pangocairo-1.0.lib pangoft2-1.0.lib pangowin32-1.0.lib
(or you can go to your library path via a command prompt and enter dir *.lib /B)
Don't forget to include the /ENTRY:mainCRTStartup flag mention in the initial answer you started with.
you may have to edit your project settings or use a pragma comment to link with your gtk library:
#pragma comment(lib, "gtk-3")//if the libray is on your project's path
#define PATH "C:\\example\\"
#pragma comment(lib, PATH"gtk-3")//if the library is on PATH
I am not able to link RtlIpv4StringToAddressExW(). This is a simplified version of my program.
#include <WinSock2.h>
#pragma comment(lib, "ws2_32.lib")
#include <Windows.h>
#include <cstdio>
#include <MSTcpIP.h>
HRESULT doMAin()
{
LONG error;
PSOCKADDR_IN sin4;
error = RtlIpv4StringToAddressExW(
L"127.0.0.1",
TRUE,
&sin4->sin_addr,
&sin4->sin_port);
return S_OK;
}
And the error I am getting is:
main.obj : error LNK2001: unresolved external symbol __imp__RtlIpv4StringToAddressExW#16
Does anyone know what could be wrong?
"An import library containing the RtlIpv4StringToAddressEx function is not included in the Microsoft Windows Software Development Kit (SDK) released for Windows Vista. The RtlIpv4StringToAddressEx function is included in the Ntdll.lib import library included in the Windows Driver Kit (WDK). An application could also use the GetModuleHandle and GetProcAddress functions to retrieve the function pointer from the Ntdll.dll and call this function."
from the docs.
If there was a lib to pragma comment, it would be Ntdll.lib. To repeat the docs, you can either grab the one from the DDK, or GetProcAddress the sucker.
GetProcAddressing would look like
typedef LONG (NTAPI *pfRtlIpv4StringToAddressEx)(PCWSTR,BOOLEAN,IN_ADDR *,PUSHORT);
pfRtlIpv4StringToAddressEx pRtlIpv4StringToAddressEx = (pfRtlIpv4StringToAddressEx)GetProcAddress(GetModuleHandle("ntdll.dll"), "RtlIpv4StringToAddressExW");
error = (*pRtlIpv4StringToAddressEx)(
L"127.0.0.1",
TRUE,
&sin4->sin_addr,
&sin4->sin_port);
