 |
|
Dear all:
I have an BCB application, which should invoke another application to
execute some command.
for example, i would like invoke a command like this: " bslw200.exe -b
19200 -e cpu1568 sbu410.hex";
How can i do it??
Thank you in advance. |

Look at the CreateProcess() function in the Win32 API.

Thank you for your hint!
but i still has problem.since my addtional application is a command line
application(bslw200.exe), it needs dos shell to run it.
here is source code:
AnsiString strCmd = AnsiString("c:\\windows\\system32\\cmd.exe /c start ");
AnsiString strCmdLine = AnsiString("f:\\bslw200.exe -b 38400 -r
sbu410.hex");
PROCESS_INFORMATION piProcInfo;
STARTUPINFO siStartInfo;
// Set up members of STARTUPINFO structure.
siStartInfo.cb = sizeof(STARTUPINFO);
siStartInfo.lpReserved = NULL;
siStartInfo.lpReserved2 = NULL;
siStartInfo.cbReserved2 = 0;
siStartInfo.lpDesktop = NULL;
siStartInfo.dwFlags = 0;
// Create the child process.
CreateProcess(
strCmd.c_str(),
strCmdLine.c_str(),
NULL, // process security attributes
NULL, // primary thread security attributes
0, // handles are inherited
0, // creation flags
NULL, // use parent's environment
NULL, // use parent's current directory
&siStartInfo, // STARTUPINFO pointer
&piProcInfo); // receives PROCESS_INFORMATION
I don't know what wrong with it. Can you help me?

So? Every win32 application has a command line available. You can
run an application without caring whether it requires a console or
not.

A DOS console will be created automatically when CreateProcess() tries
to run a console application. The console will be freed after the
console application exits. So what exactly are you having a problem
with?

You don't need that. The OS already know which command processor to
use. You can run bslw200.exe directly instead, ie:
STARTUPINFO siStartInfo = {sizeof(STARTUPINFO), 0};
PROCESS_INFORMATION piProcInfo = {0};
CreateProcess(
NULL,
"f:\\bslw200.exe -b 38400 -r sbu410.hex",
NULL,
NULL,
0,
0,
NULL,
NULL,
&siStartInfo,
&piProcInfo);

there is no console open, The bslw200 command can't be execute. when
bslw200 is executing, it will look into Serial interface and wait for a
response from other component in our system, the timeout period of waiting
is quite long.
I don't know whether it is feasible to send you relative files to
you(bslw200 and so on), maybe you can see my problem more clearly.
Thanks you very much for your answer.

| Quote: | Actually, it doesn't work with CreateProcess
|
Yes, it does. CreateProcess() works with DOS console applications
just fine. I have several projects of my own that run console
utilities and they run without any problems.
| Quote: | there is no console open
|
Yes, there is. It may be hidden by default, though. You can use the
STARTUPINFO structure to tell CreateProcess() to show the console
window, ie:
siStartInfo.dwFlags = STARTF_USESHOWWINDOW;
siStartInfo.wShowWindow = SW_SHOW;
| Quote: | The bslw200 command can't be execute.

Yes, it can.

CreateProcess() does not wait for the spawned executable to finish its
work. It always exits immediately. If you need to wait for the DOS
application to finish, then you need to use WaitForSingleObject(), or
GetExitCodeProcess() in a loop. For example:
if( CreateProcess(...) )
{
CloseHandle(piProcInfo.hThread);
WaitForSingleObject(piProcInfo.hProcess, INFINITE);
CloseHandle(piProcInfo.hProcess);
}
Or:
if( CreateProcess(...) )
{
CloseHandle(piProcInfo.hThread);
DWORD dwExitCode;
while( GetExitCodeProcess(piProcInfo.hProcess, &dwExitCode) )
{
if( dwExitCode != STILL_ACTIVE )
break;
Sleep(1000);
}
CloseHandle(piProcInfo.hProcess);
}

That will not be necessary.
