void CCommandDlg::OnOK()
{
// TODO: Add extra validation here
UpdateData(true);
AfxMessageBox(m_ipstart);
AfxMessageBox(m_ipend);
CString parameter;
parameter = "ipscan" + m_ipstart + " " + m_ipend + "text8.txt";

ShellExecute (NULL, "Open", "C:\WINDOWS\Desktop\Ipscan.exe", parameter, "C:\WINDOWS\Desktop", SW_MAXIMIZE);

try to do it like this:

ShellExecute (NULL, "Open", "C:/WINDOWS/Desktop/Ipscan.exe", 
	parameter, "C:/WINDOWS/Desktop",  SW_MAXIMIZE);

May be, you forget: backslash in C/C++ string literals is an escape character. You must write it twice: "C:\\Windows...", not "C:\Win...".

Better is to use CreateProcess insetad of ShellExecute

Why is it considered better to use CreateProcess instead of ShellExecute?

 

[Cagliostro]

ShellExecute returns a value what is not a true hinstance of a process. So you can not use it to wait until termination or to close that process. Moreover, it is a simulation of anything what you can do with doubleckick on windows explorer or type in cmd line. Would be very interesting, how will you use results of execution... For example the process terminated with error.. Let's imaginate, you create an install programm and to install you should call the installer of other program and after that install yours. The instalation of first one failed... How will you handle this situation? Or you know what if instalation is more than 10 sec(for example) the instalation hangs up and you should abort instalation... You will be able only to use CreateProcess where.
