How to terminate process

[Davidw]

Hi,
I am trying to terminate a running process.

HANDLE lProcSnapshot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
lRes=Process32First(lProcSnapshot,&procEntry);
while(lRes)
{
if (procEntry.szExeFile == "myapp.exe")
{
hProcess = (HANDLE)procEntry.th32ProcessID;
if (!TerminateProcess(hProcess,113))
{
dwLaseError = GetLastError();
}
break;
}
lRes=Process32Next(lProcSnapshot,&procEntry);
}
CloseToolhelp32Snapshot(lProcSnapshot);

The process found, but I get dwLaseError = 6
Which is: ERROR_INVALID_HANDLE The handle is invalid.

Thanks,
David

The handle is invalid because you casting procEntry.th32ProcessID (the
process ID, a number) to a handle.

Given the process ID you can pass it to OpenProcess to retrieve the handle
to use in TerminateProcess.

Check even %_WINCEROOT%\PUBLIC\WCESHELLFE\OAK\TASKMAN to see how Task
Manager kills processes

In addition to Luca's very clear response, I'd like to note that you really,
really don't want to terminate a process, in most cases. Bad things happen
when you do this. The only case where it makes sense is when the process is
irrevocably locked and you have to exit it to keep the device operational.
That is, if you are doing some 'scripting' of the device (open Pocket Word,
do some stuff, close Pocket Word), you should not do the close operation via
TerminateProcess.

I just posted a function to kill a process on my blog at
