获取当前应用程序的文件名

获取应用程序名称，如果文件名在运行时被改变，QueryFullProcessImageName()同样可以获取文件名。

#include "stdafx.h"
#include <Windows.h>
#include <Psapi.h>
#include <stdio.h>

#pragma comment(lib, "Psapi.lib")

void OutputSelfpath()
{
    char szFile[MAX_PATH] = {0};
    GetModuleFileName(NULL, szFile, MAX_PATH);
    printf("GetModuleFileName:

%s

", szFile);

    memset(szFile, 0, MAX_PATH);

    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, GetCurrentProcessId());
    if (!hProcess)
    {
        printf("OpenProcess failed!
");
    }
    else
    {
        DWORD dwRet = GetProcessImageFileName(hProcess, szFile, MAX_PATH);
        if (dwRet)
        {
            printf("GetProcessImageFileName:

%s

", szFile);
        }
        else
        {
            printf("GetProcessImageFileName failed!
");
        }

        DWORD dwSize = MAX_PATH;
        if (QueryFullProcessImageName(hProcess, 0, szFile, &dwSize))
        {
            printf("QueryFullProcessImageName:

%s

", szFile);
        }
        else
        {
            printf("QueryFullProcessImageName failed
", szFile);
        }
    }
}

int main()
{
    const char* pszFile = "ConsoleTest.exe";
    const char* pszNewFile = "ConsoleTest_bak.exe";
    remove(pszNewFile);

    OutputSelfpath();
    
    int nRet = rename(pszFile, pszNewFile);

    if (0 != nRet)
    {
        printf("rename file failed!
");
    }
    else
    {
        OutputSelfpath();
    }

    system("pause");
    return 0;
}
