如何使用shell32.dll从C ++控制台应用程序 [英] How to use shell32.dll from C++ console application
问题描述
我需要做的是得到 ApplicationData
路径,我发现在Google有一个函数叫做
HRESULT SHGetFolderPath(
__in HWND hwndOwner,
__in int nFolder,
__in HANDLE hToken,
__in DWORD dwFlags,
__out LPTSTR pszPath
);
但它存在于shell32.dll
在C#中,我会做一些类似
[DllImport]
static extern HRESULT SHGetFolderPath()等。
在C ++控制台应用程序中需要做什么,才能调用此API?
也许,我可以使用 LoadLibrary()
?
但是什么是正确的方法呢?
我可以以静态方式将此dll链接到我的exe中吗?
我使用Visual Studio 2010。
您需要#include shlobj.h并链接到shell32.lib 。像这样:
#includestdafx.h
#include< windows.h>
#include< shlobj.h>
#include< assert.h>
#pragma comment(lib,shell32.lib)
int _tmain(int argc,_TCHAR * argv [])
{
TCHAR路径[MAX_PATH] ;
HRESULT hr = SHGetFolderPath(NULL,CSIDL_APPDATA,NULL,0,path);
assert(SUCCEEDED(hr));
//等..
return 0;
}
#pragma注释告诉链接器。 >
What I need to do is to get ApplicationData
path , I've found in Google that there is function called
HRESULT SHGetFolderPath(
__in HWND hwndOwner,
__in int nFolder,
__in HANDLE hToken,
__in DWORD dwFlags,
__out LPTSTR pszPath
);
But it exists in shell32.dll In C# I'd do something like
[DllImport]
static extern HRESULT SHGetFolderPath() and so on.
What do I need to do in C++ Console application, to be able to call this API?
Maybe, I can use LoadLibrary()
?
But what is the right way to do this?
Can I somehow statically link this dll to be part of my exe? I am using Visual Studio 2010.
You need to #include shlobj.h and link to shell32.lib. Like this:
#include "stdafx.h"
#include <windows.h>
#include <shlobj.h>
#include <assert.h>
#pragma comment(lib, "shell32.lib")
int _tmain(int argc, _TCHAR* argv[])
{
TCHAR path[MAX_PATH];
HRESULT hr = SHGetFolderPath(NULL, CSIDL_APPDATA, NULL, 0, path);
assert(SUCCEEDED(hr));
// etc..
return 0;
}
The #pragma comment takes care of telling the linker about it.
