SA-MP trainer, need help
Hi !
I have a question for those that play SA-MP and are creating cheats for it.Is there some way to create a trainer for this in VB.NET ?
And, are GTA SA/ SA-MP's adresses static or dynamic ? Last time i was testing with Cheat Engine, i could change money value from CE, however when i used ReadWriteMemory for vb.net then it couldnt find my gta_sa.exe process, could someone make a simple tutorial for trainer to this game, that will work all the time ?

Just look here - Grand Theft Auto San Andreas Multi Player (SAMP) Hacks - MPGH - MultiPlayer Game Hacking & Cheats - Hacks, Cheats, Downloads, Trainers, Games

Also, instead of asking for help on the forums for a "simple" tutorial on how to hack SA-MP learn how to code.

if you have skype and teamview, I'll show you a couple things with cheatengine and vb.net if you want.

skype is same as my username here.

Hi guys!
Im not some complete noob, i know how to make basic programs, and i got a class to change address values.I have made money hack, unlimited ammo and +100 to money.However i want to change health value, that is a dynamic address.Its pretty simple to find out the address in CE, everything is given here:
Memory Addresses (SA) - GTAModding
Just need to add pointer (CPed) and 0x540 values and voila you got the address and you can change the health value.BUT, i want to do this in VB.NET
I got a class, that can read a dynamic address, write a dynamic addres etc, however its same class that i had problems with some time ago.When i try to use it, it shows a MessageBox with "Failed to open gta_sa" so it detects the process, but idk whats wrong (if i try to use it on a non existing process, it says "process_name isnt open"

Module:
Code:
Module dynamiczne

Functions im trying to use are getAddress, readDynamicInt etc (however i will probably need to use readDynamicFloat as health is float type, but i cant it even get to work)
Someone knows what is wrong here ? Some guy told me it works for him, im using Windows XP SP3 and it doesnt for me

Yes because using Cheat Engine is the really l33t way of making hacks. It's like copy & paste in a sense. You didn't really do any heavy lifting just minimal efforts.

Stahp, you are really hurting my feelings! Seriously though, you look like a hardcore leecher with a skiddie attitude.

"Just need to add pointer (CPed) and 0x540 values and voila you got the address and you can change the health value.BUT, i want to do this in VB.NET"
Code:
Dim ptr1 as Intptr = MemMgr.ReadIntPtr(someAddr) 
Dim ptr2 as IntPtr = Memmgr.ReadIntPtr(ptr1 + &H540) '// Depending on Framework version, you can't ++ on IntPtr.  See IntPtr.Add()
?? Ofc you don't have a function called ReadIntPtr() but you should, and you should understand what it is. Ofc it's possible in vb.net :/ But you have to understand pointers and when/why they are used.

The way you overload RPM is a little weird. I think maybe you should re-structure your class/functions a little.

edit: I read that wrong, sounds like you only need.. (which ofc is still possible in vb.net)
Code:
Dim ptr1 as IntPtr = MemMgr.ReadIntPtr(someAddr)
Dim ptr2 as IntPtr = ptr1 + &H540 '' aka Addr of health value

Dim healthValue as Int32 = MemMgr.ReadInt32(ptr2) '// i assume health is stored as int32
??

Both of you.

CE is an awesome tool (scanner / debugger + more).

OP needs a proper memory library and to understand how it all works / why before attempting something this relatively complex. First learn to read the score value from pinball or something easy, then when you know your memory library works, move on to larger projects. Your code might compile and sort-of work, but it has several nuances that are going to cause you more work later..especially if you don't understand how it all works. Go to the 2nd page of the vb coding section, I wrote a tut w/ a lot of source and explain some of the concepts. You have to know how to program before trying to make a program...obviously.
