Hello All, I am trying to figure out how to execute a third party program
and then stop it and can not seem to figure out how to stop it.

I am using this code to execute it and "Terminate" it, the execute works
fine but the TerminateProcess dosn't.

Here is how I start the app:
myApp.Classes.Globals.testID =
PMMobile.Classes.SHELLEXECUTEEX.ExecuteFile("\\program
files\\WebTechWireless\\wtwnav.exe","");


My Code:


public class SHELLEXECUTEEX
{
public UInt32 cbSize;
public UInt32 fMask;
public IntPtr hwnd;
public IntPtr lpVerb;
public IntPtr lpFile;
public IntPtr lpParameters;
public IntPtr lpDirectory;
public int nShow;
public IntPtr hInstApp;
// Optional members
public IntPtr lpIDList;
public IntPtr lpClass;
public IntPtr hkeyClass;
public UInt32 dwHotKey;
public IntPtr hIcon;
public IntPtr hProcess;

[DllImport("coredll")]
extern static IntPtr ShellExecuteEx( SHELLEXECUTEEX ex );

[DllImport("coredll", EntryPoint="TerminateProcess", SetLastError=true)]
extern static int TerminateProcess(IntPtr hProcess, int uExitCode);

[DllImport("coredll")]
extern static IntPtr LocalAlloc( int flags, int size );

[DllImport("coredll")]
extern static void LocalFree( IntPtr ptr );

public static void StopProcess()
{
int temp = TerminateProcess(myApp.Classes.Globals.testID,0);
}


public static IntPtr ExecuteFile(string strFileName, string strParameters)
{
int nSize = strFileName.Length * 2 + 2;
IntPtr pData = LocalAlloc(0x40, nSize);
Marshal.Copy(Encoding.Unicode.GetBytes(strFileName), 0, pData, nSize -
2);

SHELLEXECUTEEX see = new SHELLEXECUTEEX();
see.cbSize = 60;
see.dwHotKey = 0;
see.fMask = 0;
see.hIcon = IntPtr.Zero;
see.hInstApp = IntPtr.Zero;
see.hProcess = IntPtr.Zero;
see.lpClass = IntPtr.Zero;
see.lpDirectory = IntPtr.Zero;

see.lpIDList = IntPtr.Zero;
if(strParameters.Trim().Length == 0)
{
see.lpParameters = IntPtr.Zero;
}
else
{
int nSizePar = strParameters.Length * 2 + 2;
IntPtr pDataPar = LocalAlloc(0x40, nSizePar);
Marshal.Copy(Encoding.Unicode.GetBytes(strParameters), 0, pDataPar,
nSizePar - 2);
see.lpParameters = pDataPar;
}

see.lpVerb = IntPtr.Zero;
see.nShow = 0;
see.lpFile = pData;
LocalFree(pData);
return see.hProcess;
}
}
 
Thanks, I will see if I can figure how they do it since I do not want to use
the SDF.

Hint: If you don't want to use the SDF binary, or don't want to borrow the
code, then you can at least be "inspired" by it!

Why not use SDF?

In any case, using TerminateProcess() is not a suitable way to cleanly stop
a process (it's a last resort method of shutting down a process which is
messed up). We've been over the list of other things that you might do with
respect to stopping a second application. You can search for them (probably
searching on TerminateProcess is the best way to find them), in the
archives:
