[游戏开发]使用ShellExecuteW执行exe并传入参数

ShellExecuteW函数用法

#include <iostream>
#include <Windows.h>
#include <string>
using namespace std;
wchar_t* string_2_LPCWSTR(string orig)
{
	size_t origsize = orig.length() + 1;
	const size_t newsize = 100;
	size_t convertedChars = 0;
	wchar_t* wcstring = (wchar_t*)malloc(sizeof(wchar_t) * (orig.length() - 1));
	mbstowcs_s(&convertedChars, wcstring, origsize, orig.c_str(), _TRUNCATE);
	return wcstring;
}
int main(int argc,char *argv[])
{
    string path = "test.exe";	//这个exe是打印传入的两个参数
    string argv1 = "1", argv2 = "2";
	HINSTANCE x;
	x = ShellExecuteW(
			NULL, 
			string_2_LPCWSTR("open"), 
			string_2_LPCWSTR(path), 
			string_2_LPCWSTR(argv1 + " " + argv2), 
			NULL, 
			SW_SHOW);
	if ((INT_PTR)x < 32) cout << GetLastError() << endl;
	return 0;
}
