ShellExecuteEx

**Magos** · 03-01-2006

I have this oddity when calling ShellExecuteEx with SEE_MASK_NOCLOSEPROCESS in the fMask member. The function returns TRUE as in success but the hProcess member is still NULL. How can this be? If no process remains shouldn't the function return FALSE?

EDIT: nm, for some reason this error disappeared. Must've been a recompilation or something...

Use to indicate that the hProcess member receives the process handle. This handle is typically used to allow an application to find out when a process created with ShellExecuteEx terminates. In some cases, such as when execution is satisfied through a DDE conversation, no handle will be returned. The calling application is responsible for closing the handle when it is no longer needed.

Often, you'll get a process handle only if there is no instance of the program open when you make the call.

Magos, I noticed that you asked a question about a browser through your program, and that
someone answered with ShellExecuteEx() and SEE_MASK_NOCLOSEPROCESS. And now
you are asking a question about ShellExecuteEx() and SEE_MASK_NOCLOSEPROCESS,
meaning you have some script to have a browser in your program? If so, could you share the code
you have with me? The reason I am asking is because I have tried to use ShellExecuteEx() before,
and I couldn't get it to work, so if I got some working code, it would help me.

Thanks, August.

I have no browser, that was another guy.
Launching a new process aint that hard though:

Code:

SHELLEXECUTEINFO Info;
std::string FileName;

FileName = "C:\\MyFile.txt";

ZeroMemory(&Info, sizeof(SHELLEXECUTEINFO));
Info.cbSize = sizeof(SHELLEXECUTEINFO);
Info.fMask = SEE_MASK_NOCLOSEPROCESS | SEE_MASK_FLAG_NO_UI;
Info.lpFile = FileName.c_str();
Info.hInstApp = GetModuleHandle(NULL);
Info.nShow = SW_SHOW;

if(!ShellExecuteEx(&Info)) return FALSE;

//The created process is in:
Info.hProcess;
