Escaping Dash Character in batch file using Visual C++ -

i working on simple program in file containing computer names read c++ file seen in following:

//previously, file containing names opened ,  //getline() in use read each line //note 'line' string containing current line being read   string comp = lower(trim(line.erase(0, 2)));  //lower converts lowercase (for later in program) ,  //trim trims beginning , ends of string.   //i have erased first 2 characters, since contain 2 \'s ofstream bat; bat.open("names_get.bat"); if (bat.is_open()) {                                          bat << "wmic.exe /node:"+comp+" computersystem username >compnames.txt";     bat.close(); } 

this functions well. however, encountering problem when batch file executed using shellexecute. problem command prompt encountering computer names such "owner-pc" , taking - parameter, resulting in invalid global switch error. can please point me in correct direction concerning how escape dash in such event. thank you, , sorry long question!

you should surround compname "like

 wmic.exe /node:"prefix-suffix" computersystem username 

so add \" in code , should work

if (bat.is_open()) {                                          bat << "wmic.exe /node:\""+comp+"\" computersystem username >compnames.txt";     bat.close(); }
