You can use the BitConverter.GetBytes() method to convert another type to bytes, or simply declate the array and type the value reversed, for example for 65534 you could do:
new byte[] { 0xFE, 0xFF }

Tombana, you beat me to it. A byte can only go up to 255, so try using int instead, because i'm pretty sure it can go up to 3903284824284284207402057207507 and higher.

Just be careful to take the Endianness into account when writing bytes like that.

Range - signed = -(2^(nBits-1))~2^(nBits-1)-1
Range - unsigned = 0~2^nBits-1

For example:
signed 32-bit: -(2^31)~2^(31)-1 = -2147483648~2147483647
unsigned 32-bit: 0~2^32-1 = 4294967296-1 = 4294967295

2 problems here.

<DllImport("kernel32.dll")> _
Public Shared Function WriteProcessMemory( _
ByVal hProcess As IntPtr, _
ByVal lpBaseAddress As IntPtr, _
ByVal lpBuffer As Byte(), _
ByVal nSize As UInt32, _
ByRef lpNumberOfBytesWritten As UInt32 _
) As Boolean
End Function


1. your buffer is not just a byte, but a byte array.


WriteProcessMemory(hProcess(0).Handle, &H100579C, New Byte() {255}, 4, 0)

2. your byte array of 1 is writing 4 bytes. where are the other 3 coming from?

if you wanna write a specific amount of bytes to memory try lopping off the array part (ByVal lpBuffer As Byte) designate an array of bytes (dim mybytes() as byte) and then write them (WriteProcessMemory(Handle, address, mybytes(0), amountofbytes, 0))

if you want to write 436434 to memory change the buffer to an int or something (ByVal lpBuffer As integer) (dim hax as integer = 436434 ) (WriteProcessMemory(Handle, address, hax, 4 , 0))

you write 4 bytes the second time because an int is 4 bytes (in most cases. definitely yours.)


*note* if anything is incorrect or doesn't work, do note that i wrote it in the browser. you may need to change some stuff.

or you could use two writeprocessmemory s and... yea.

Just use the BitConverter class, it has a method that will convert whatever to a byte array.
