如何在win32中使用GetSaveFileName保存文件? [英] how to save file with GetSaveFileName in win32?

问题描述

我编写此代码是为了让 fileName 保存我的文件:

I write this code to get fileName to save my file :

#include "stdafx.h"
#include <windows.h>


int _tmain(int argc, _TCHAR* argv[])
{            
    OPENFILENAME ofn;

    char szFileName[MAX_PATH] = "";

    ZeroMemory(&ofn, sizeof(ofn));

    ofn.lStructSize = sizeof(ofn); 
    ofn.hwndOwner = NULL;
    ofn.lpstrFilter = (LPCWSTR)L"Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
    ofn.lpstrFile = (LPWSTR)szFileName;
    ofn.nMaxFile = MAX_PATH;
    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
    ofn.lpstrDefExt = (LPCWSTR)L"txt";

    GetSaveFileName(&ofn);
    printf("the path is : %s\n", ofn.lpstrFile);
    getchar();
    return 0;
}

但输出是:

 the path is : H 

为什么?我做错了什么吗?
我在 Windows 7 上使用 Visual Studio 2008.

why ? Am I doing something wrong ?
I'm using Visual Studio 2008 on Windows 7.

推荐答案

这一行:

printf("the path is : %s\n", ofn.lpstrFile);

应该使用 printf 的宽字符版本.

should use the wide char version of printf.

wprintf(L"the path is : %s\n", ofn.lpstrFile);
