C# Signature:
[DllImport("kernel32.dll")]
static extern bool WriteProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress,
byte [] lpBuffer, uint nSize, out int lpNumberOfBytesWritten);
VB.Net Signature:
<DllImport("kernel32.dll")> _
Public Shared Function WriteProcessMemory(ByVal hProcess As IntPtr, ByVal lpBaseAddress As IntPtr, ByVal lpBuffer As Byte(), ByVal nSize As UInt, <Out()> ByRef lpNumberOfBytesWritten As Int) As Boolean
End Function
User-Defined Types:
None.
Notes:
None.
Tips & Tricks:
Please add some!
Sample Code:
public int WriteByteArray( IntPtr BaseAddress, byte [] NewVal )
{
// Return Value
int ReturnVal;
// Write Memory Byte Array
ReturnVal = WriteProcessMemory( this.hProcess, BaseAddress, NewVal, NewVal.Length, out this.BytesWritten );
return this.BytesWritten;
}
'VB.Net
Public Shared Function Poke(ByVal proc As Process, ByVal target As Integer, ByVal data As Byte()) As Boolean
Return WriteProcessMemory(proc.Handle, New IntPtr(target), data, data.Length, 0)
End Function
Alternative Managed API:
The ManagedWindowsApi project (http://mwinapi.sourceforge.net) provides a ProcessMemoryChunk class to allocate and access memory of a different process.
