Question

After running the following code everything does as I would like except the folder shows this: test2﷽﷽ꮫꮫꮫꮫﻮﻮﻮ

What is going on here?

            std::string arrString[3] = {" /C mkdir C:\\Users\\Andrew\\Desktop\\test1"," /C mkdir C:\\Users\\Andrew\\Desktop\\test2"," /C mkdir C:\\Users\\Andrew\\Desktop\\test3"};
            LPWSTR cmd =L"C:\\Windows\\System32\\cmd.exe";
            int i;


            for(i=0; i<3; i++)
            {
                STARTUPINFO info={sizeof(info)};
                PROCESS_INFORMATION processInfo;
                vector<wchar_t> cmdline(arrString[i].begin(), arrString[i].end());
                CreateProcessW(cmd, &cmdline[0], NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo);
                OutputDebugStringW(L"My output\nstring.");
            }
        }

cmdline is not properly ASCIIZ terminated. You can check if this is the cause just adding an ending 0 (note: not tested and a quick hack):

cmdline.push_back(0);
