如何在本机C ++中获取进程名称和日期时间戳

Question

In Native C++, how can I get the current process Name and date time. I am not a C++ programmer.

In C#, it is very trivial to do it like this:

Process name:

Process.GetCurrentProcess().ProcessName

Date Time:

DateTime.Now.ToString("yyyy-MM-dd_HH.mm.ss.ff")

How can they be retrieved in C++ native?

Answer 1

To get the name of the current process you can use GetModuleFileName() :

char exe_path[MAX_PATH];
GetModuleFileName(NULL, exe_path, MAX_PATH);

You can then extract the part of exe_path after the last \\ character.

To get the current time, you can use std::time() .

Answer 2

GetSystemTime

Syntax

void WINAPI GetSystemTime(
  __out  LPSYSTEMTIME lpSystemTime
);

Parameters: lpSystemTime [out]

A pointer to a SYSTEMTIME structure to receive the current system date and time. The lpSystemTime parameter must not be NULL. Using NULL will result in an access violation.

Return value: This function does not return a value or provide extended error information.

Remarks: To set the current system date and time, use the SetSystemTime function.

Requirements: Minimum supported client Windows 2000 Professional

Minimum supported server: Windows 2000 Server

Header : Winbase.h (include Windows.h)

Library : Kernel32.lib

DLL : Kernel32.dll

And for process name:

QueryFullProcessImageName function

GetModuleFileNameEx function

Answer 3

Process name:

char name[256];
GetProcessImageFileName(GetCurrentProcess(),name,256);

You can also get it from the command-line arguments

And for the date use localtime() from time.h, example here
