[VB2010exp] ending a process

[gh0st]

well guys I would like to make a tool in visual basic 2010 express which ends a specific process by just pressing f1 or any other buttom
any kind of suggestion will be apreciated thanx in advance

Code: [Select]

shell("tskill NAME")

That will kill your process, by name NAME. To make it work with a hotkey(globally), you have to look into the GetAsyncKeyState(). Here is an example:

Code: [Select]

<DllImport("user32.dll")> _
Public Shared Function GetAsyncKeyState(ByVal vKey As System.Windows.Forms.Keys) As integer
End Function

Sub BackgroundThreadThatWillLoopForever()
while (1)
     Dim x as integer = GetAsyncKeyState(keys.f1)
     If x = 1 or x = -32767 then
          shell("tskill NAME")
     End if
     System.threading.thread.sleep(1)
     application.doevents()
loop
End sub

I coded that by hand now, and have not tested it but im pretty sure that should work

[iMorg]

I would suggest using TerminateProcess and provide a handle to the process. That way if your program doesnt have the access rights to kill the selected process you can update the security token of the program.


Example:

Code: [Select]

// iMorg->EvilZone

bool KillProc(unsigned long pid)
{
     HANDLE pHandle = OpenProcess(PROCESS_ALL_ACCESS,
                                                         FALSE,
                                                         pid);
     if (pHandle == NULL)
          return false;
     if( !TerminateProcess(pHandle, 0) )
        return false;
     else
        return true;
}


To do it when a key is pressed you can use GetAsyncKeyState() as ande said or you can hook the keyboard and look for the correct message.


EDIT: Shit didnt see the VB, nvm. Ill leave it if you ever need a c++ example anyway.
