According to the docs:
"If you want your application to use ComCtl32.dll version 6, you must add an application manifest or compiler directive to specify that version 6 should be used if it is available."
Notice the logical OR above? So what is this mysterious compiler directive?
I've got a native Win32 C++ application that is wholly contained in a single .cpp file. There are no resource files, manifest files, etc. I'd like to keep it that way, but I would also like to use visual styles.
There's actually a third way with no manifests whatsoever, though it's rather hacky:
#include <windows.h>
// NOTE: It is recommended that you delay-load ComCtl32.dll (/DelayLoad:ComCtl32.dll)
// and that you ensure this code runs before GUI components are loaded.
// Otherwise, you may get weird issues, like black backgrounds in icons in image lists.
ULONG_PTR EnableVisualStyles(VOID)
{
TCHAR dir[MAX_PATH];
ULONG_PTR ulpActivationCookie = FALSE;
ACTCTX actCtx =
{
sizeof(actCtx),
ACTCTX_FLAG_RESOURCE_NAME_VALID
| ACTCTX_FLAG_SET_PROCESS_DEFAULT
| ACTCTX_FLAG_ASSEMBLY_DIRECTORY_VALID,
TEXT("shell32.dll"), 0, 0, dir, (LPCTSTR)124
};
UINT cch = GetSystemDirectory(dir, sizeof(dir) / sizeof(*dir));
if (cch >= sizeof(dir) / sizeof(*dir)) { return FALSE; /*shouldn't happen*/ }
dir[cch] = TEXT('\0');
ActivateActCtx(CreateActCtx(&actCtx), &ulpActivationCookie);
return ulpActivationCookie;
}
If you're using Visual Studio, you can add this line to your stdafx.cpp for example:
#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
If you had kept reading, you would have found the answer:
If you are using Microsoft Visual C++ 2005 or later, you can add the following compiler directive to your source code instead of manually creating a manifest. For readability, the directive is broken into two lines here.
#pragma comment(linker,"\"/manifestdependency:type='win32' name='Microsoft.Windows.Common-Controls'
version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

I am pretty new user of Eigen and have run into a weird problem. I am adding to a C++ project that uses OpenMP (Visual Studio 2012 compiler, /openmp set). I get a compilation error:
include\eigen\src/Core/products/Parallelizer.h(34): error C3861:
'omp_get_max_threads': identifier not found
I have tried to google around for an answer, but have failed to find a solution. We have another project, not using openmp, where Eigen has been used successfully for a while. Adding /openmp to that project did not trigger the problem. I also tried to disable openmp in Eigen, using the EIGEN_DONT_PARALLELIZE preprocessor directive. The problem persists. All suggestions to solve the problem are more than welcome.
Long comment, not really an answer: Something appears to be broken in your project. I'm using Eigen 3.2.9 as a reference, as you haven't specified which version you're using. In Eigen/Core (133) we have
#if (defined _OPENMP) && (!defined EIGEN_DONT_PARALLELIZE)
#define EIGEN_HAS_OPENMP
#endif
#ifdef EIGEN_HAS_OPENMP
#include <omp.h>
#endif
So, if you properly defined EIGEN_DONT_PARALLELIZE in your project, EIGEN_HAS_OPENMP shouldn't be defined and omp.h shouldn't be included. Additionally, in Parallelizer.h(30):
#ifdef EIGEN_HAS_OPENMP
if(m_maxThreads>0)
*v = m_maxThreads;
else
*v = omp_get_max_threads();
#else
*v = 1;
#endif
So if you had properly defined EIGEN_DONT_PARALLELIZE, you would not be getting the error you are getting.
Regarding the C3861 error, it means that the compiler is not able to find a declaration for omp_get_max_threads (called in Parallelizer.h). As that code is called within a #ifdef EIGEN_HAS_OPENMP as is the line #include <omp.h> in Core, and omp_get_num_threads is only wrapped in an #if defined( __cplusplus) you could add a check in Core or omp.h to make sure that the code is active
// This is in Eigen/Core
#ifdef EIGEN_HAS_OPENMP
static_assert(0, "OMP FILE IS INCLUDED IN CORE...");
#include <omp.h>
#endif
and
// This is in omp.h
static_assert(0, "OMP FILE IS PROPERLY INCLUDED...");
_OMPIMP int _OMPAPI
omp_get_num_threads(
void
);
You should get both as errors if omp is loaded correctly.
I built the simple MS example for TaskDialogIndirect (see https://msdn.microsoft.com/en-us/library/windows/desktop/bb760544(v=vs.85).aspx)
When I run it I get "The ordinal 345 could not be located in the dynamic link library COMCTL32.dll"
The above page says it needs ComCtl32.DLL version 6 but C:\Windows\System32\ComCtl32.DLL is 5.82.7601.18201 and I can't find a version 6 anywhere on the disk.
I am running Windows 7 with VS2012. TaskDialog was added in Vista so why don't I have the correct version of ComCtl32.DLL???
Here's a common and useful block of code that should help to load the correct common controls, comctl32.dll:
#if defined _M_IX86
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_IA64
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='ia64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#elif defined _M_X64
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='amd64' publicKeyToken='6595b64144ccf1df' language='*'\"")
#else
#pragma comment(linker, "/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")
#endif
There are two versions of ComCtl32.dll on Windows XP and later (SxS). v5.8x is the default, you need to opt-in to get v6 because of possible incompatibility's with the new Themes/Visual Styles. Most new features and controls have only been added to v6.
To get v6 you must add a manifest to your application. It is recommended that you embed the manifest in the applications resources but you can also use a external manifest; just name the XML file yourappname.exe.manifest.
You can run sfc /scannow to resolve this issue. [Reference].
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 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
