 |
|
I've the static address + offset of health value that is float .. when i try to make a trainer with vb.net ..
| Code: |
...blabla code blabla...
Dim val as Double = Textbox1.text
WriteProcessMemory(pHandle,Address, val, 2, 4) |
It doesnt "edit" the health value for example from 10 to 99 but if i write in textbox -> 999999 ... the hp in game go up to, for example, 11 -> 11.003456

Maybe cause your defining the value as a double instead of a float?
Try
| Code: | | Dim val As Single = TextBox1.Text |

Parse the text into your float instead of just attempting to assign it.
| Code: | Dim val As Single
If Single.TryParse(Textbox1.text, val) Then
WriteProcessMemory(pHandle,Address, val, 2, 4)
End If |
Also it would help to post your definition of WriteProcessMemory too since the protoype you give of it here does not match what it should be and appears that you are trying to write two bytes instead of the proper four for a single (float).

About tryparse and see what his api looked like, strange.
Anyway post more code. Looks like it'l be an easy fix but without knowing more about whats going on, i can't say for sure.

| Code: | | Private Declare Function WriteProcessMemory Lib "kernel32" (ByVal hProcess As Integer, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Long, ByVal nSize As Integer, ByRef lpNumberOfBytesWritten As Integer) As Integer |
It keeps add value like 0.0001526 if i write 10 in textbox ... so if i've 200 hp i get 200.0001526

a float is 4 bytes long, not 2, so change the 2 to 4

I just noticed that you declared lpBuffer as a long, which is a normal integer type.
This means that visual basic converts the float to a integer, and then passes the pointer to that
meaning that it writes the integer 333 to the memory instead of the float

Uhm, this is a VB6 method of importing an API.
So which are you using? VB.NET or VB6?
If you are using VB.NET you should import the API like this:
| Code: |
<DllImport("kernel32.dll", SetLastError:=True)> _
Public Shared Function WriteProcessMemory(ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByVal lpBuffer As Byte(), ByVal nSize As System.UInt32, <Out()> ByRef lpNumberOfBytesWritten As IntPtr) As Boolean
End Function
