program inside of a program??

[GUJUm0deL]

Is it possiable to open another C++ program inside of another?? I know some1 who has a C++ program and they wanna be able to open another C++ program inside that one...
example -- like in DOS, you can open program.exe inside of DOS... I have not failed; I merely found 100,000 different ways of not succeding...

there should be many functions. The simpliest is
system("xxx.exe" John Fill

So in the first C++ program, where does the 'system(*.exe)' go?? Towards the end?? In other words, how does the person actually call the other program to run inside the first one?? I have not failed; I merely found 100,000 different ways of not succeding...

instead of system(*.exe) put system("*.exe") John Fill

ok, but where in the first program would that go?? in the bottom at the top?? Does anything else have to called to bring up the second program?? Just add: system("*.exe&quot and thas it?? I have not failed; I merely found 100,000 different ways of not succeding...

you should call one by one programs by theirs names
system("xx.exe"
system("xxx.exe"
system("c:\\xxx\\yyyy.exe" John Fill

Use the API call Create Process. You will need Winbase.h and kernel32.lib if you are not inside a Visual C++.

BOOL CreateProcess(
LPCTSTR pApplicationName,// name of executable module
LPTSTR lpCommandLine, // command line string
LPSECURITY_ATTRIBUTES lpProcessAttributes, // SD
LPSECURITY_ATTRIBUTES lpThreadAttributes, // SD
BOOL bInheritHandles, // handle inheritance option
DWORD dwCreationFlags, // creation flags
LPVOID lpEnvironment, // new environment block
LPCTSTR lpCurrentDirectory, // current directory name
LPSTARTUPINFO lpStartupInfo, // startup information
LPPROCESS_INFORMATION lpProcessInformation // process information
);

I Know it is a little bit lengthy, but it works like a charm, and you get also control of the created process(exe).

Hope this helps,

I want to do something similar. I have an executable that I do not have access to source that I want to run within a windows program and get the output from it (mainly stderr). I had it working using non-visual c++ using popen, however that won't work now that I'm coding a windows app. I tried using the section "Creating a Child Process with Redirected Input and Output" in the Win32 SDK, but I'm new to Vis C++ and couldn't get it to work. Can somebody please help me/walk me through this?
