【Win32】打开文件，选择文件夹的实现

这里只提供代码。

//打开文件
BOOL OpenFile(CString& strPath)
{
	//定义相应变量
	OPENFILENAME ofn;
	wchar_t file[MAX_PATH] = TEXT("");

	//对变量进行初始化 - 设置相应属性
	ZeroMemory(&ofn, sizeof(ofn));
	ZeroMemory(file, MAX_PATH);
	ofn.lStructSize = sizeof(OPENFILENAME);
	ofn.lpstrFilter = TEXT("音乐文件 (wav/mp3/flac)\0*.wav;*.mp3;*.flac\0All files\0*.*\0\0");
	ofn.lpstrFile = file;
	ofn.nMaxFile = MAX_PATH;
	ofn.Flags = OFN_FILEMUSTEXIST;

	//选择文件
	if(!GetOpenFileName(&ofn))
	{
		return FALSE;
	}
	strPath = ofn.lpstrFile;
#ifdef DEBUG
	//弹框提示文件信息
	MessageBox(NULL, strPath, TEXT("文件名称"), MB_OK);
#endif
	return TRUE;
}

//选择文件夹
BOOL SelectDir(HWND hWnd, CString &strPath)
{
	//定义相应变量
	BROWSEINFO bifolder;
	LPITEMIDLIST idl;
	WCHAR FileName[MAX_PATH];

	//初始化变量
	ZeroMemory(&bifolder, sizeof(BROWSEINFO));
	ZeroMemory(&FileName, MAX_PATH);
	bifolder.hwndOwner = hWnd;								// 拥有者句柄  
	bifolder.pszDisplayName = FileName;						// 存放目录路径缓冲区  
	bifolder.lpszTitle = TEXT("请选择文件夹");				// 标题  
	bifolder.ulFlags = BIF_NEWDIALOGSTYLE | BIF_EDITBOX;	// 新的样式,带编辑框  

	if(!(idl = SHBrowseForFolder(&bifolder)))
	{
		return FALSE;
	}
	SHGetPathFromIDList(idl, FileName);
	strPath = FileName;

#ifdef DEBUG
	//弹框提示文件信息
	MessageBox(NULL, strPath, TEXT("文件夹名称"), MB_OK);
#endif

	return TRUE;
}

//打开文件

BOOL OpenFile(CString& strPath)

{

//定义相应变量

OPENFILENAME ofn;

wchar_t file[MAX_PATH] = TEXT("");

//对变量进行初始化 - 设置相应属性

ZeroMemory(&ofn, sizeof(ofn));

ZeroMemory(file, MAX_PATH);

ofn.lStructSize = sizeof(OPENFILENAME);

ofn.lpstrFilter = TEXT("音乐文件 (wav/mp3/flac)\0*.wav;*.mp3;*.flac\0All files\0*.*\0\0");

ofn.lpstrFile = file;

ofn.nMaxFile = MAX_PATH;

ofn.Flags = OFN_FILEMUSTEXIST;

//选择文件

if(!GetOpenFileName(&ofn))

{

return FALSE;

}

strPath = ofn.lpstrFile;

#ifdef DEBUG

//弹框提示文件信息

MessageBox(NULL, strPath, TEXT("文件名称"), MB_OK);

#endif

return TRUE;

}

//选择文件夹

BOOL SelectDir(HWND hWnd, CString &strPath)

{

//定义相应变量

BROWSEINFO bifolder;

LPITEMIDLIST idl;

WCHAR FileName[MAX_PATH];

//初始化变量

ZeroMemory(&bifolder, sizeof(BROWSEINFO));

ZeroMemory(&FileName, MAX_PATH);

bifolder.hwndOwner = hWnd; // 拥有者句柄

bifolder.pszDisplayName = FileName; // 存放目录路径缓冲区

bifolder.lpszTitle = TEXT("请选择文件夹"); // 标题

bifolder.ulFlags = BIF_NEWDIALOGSTYLE | BIF_EDITBOX; // 新的样式,带编辑框

if(!(idl = SHBrowseForFolder(&bifolder)))

{

return FALSE;

}

SHGetPathFromIDList(idl, FileName);

strPath = FileName;

#ifdef DEBUG

//弹框提示文件信息

MessageBox(NULL, strPath, TEXT("文件夹名称"), MB_OK);

#endif

return TRUE;

}

使用头文件如下：

#include “shlwapi.h”
#include “shlobj.h”
#include <windows.h>
#include <atlstr.h>

#pragma comment(lib, “shlwapi.lib”)
