C语言根据进程名字查找进程

效果如下:

#include "stdafx.h"
#include 
#include 
#include 
#include 

BOOL judge = FALSE;

DWORD GetProcessID(char *ProcessName){
	PROCESSENTRY32 pe32;
	pe32.dwSize = sizeof(pe32);

	HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
	if (hProcessSnap == INVALID_HANDLE_VALUE){
		printf("CreateToolhelp32Snapshot errorn");
		return 0;
	}

	BOOL bProcess = Process32First(hProcessSnap, &pe32);
	while (bProcess){
	char* str1 = pe32.szExeFile;
		char* str2 = ProcessName;

		// 创建一个字符串数组
		char arr1[255] = { 0 };		

		// 利用字符串拷贝函数进行拷贝
		strcpy(arr1, str1);

		// 例如内存拷贝函数进行拷贝
		memcpy(arr1, str1, sizeof(arr1));

		// 创建一个字符串数组
		char arr2[255] = { 0 };

		// 利用字符串拷贝函数进行拷贝
		strcpy(arr2, str2);

		// 例如内存拷贝函数进行拷贝
		memcpy(arr2, str2, sizeof(arr2));



		if (strcmp(strupr(arr1), strupr(arr2)) == 0){
			judge = true;
		}

		
		bProcess = Process32Next(hProcessSnap, &pe32);
	}
	CloseHandle(hProcessSnap);
	return 0;
}

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)

	GetProcessID("chrome.exe");

	if (judge == TRUE){
		MessageBox(NULL, "find chrome.exe ","Test",0);
	}else{
