文件前加上
Imports System.Management
''' summary
''' 获取系统内存大小
''' /summary
''' returns内存大小（单位Byte）/returns
Private shared Function GetPhisicalMemory()As Long
dim searcher = new ManagementObjectSearcher() '用于查询一些如系统信息的管理对象
searcher.Query = new SelectQuery("Win32_PhysicalMemory ", "", new string() { "Capacity" })'设置查询条件
dim collection = searcher.Get() '获取内存容量
dim em = collection.GetEnumerator()
dim capacity as long= 0
While (em.MoveNext())
dim baseObj = em.Current
If (baseObj.Properties("Capacity").Value IsNot Nothing) Then
Try
capacity += long.Parse(baseObj.Properties("Capacity").Value.ToString())
Catch
return 0
End Try
End If
End While
return capacity
End Function
vb.net 读取内存失败 求高手解答
你是想读取游戏进程吧 这个问题刚开始也 让我郁闷了很久 其实很多 游戏对读取内存做了特殊处理 常规的 调用api打开进程 读取内存 无效可以尝试 用token 直接调用就ok了 返回true说明调用成功下面是详细代码 Public Class ToKen
#Region "常数及结构声明"
Private Const SE_PRIVILEGE_ENABLED As Int32 = 2
Private Const EWX_SHUTDOWN As Int32 = 1
Private Const EWX_REBOOT As Int32 = 2
Private Const EWX_LOGOFF As Int32 = 0
Private Structure LUID_AND_ATTRIBUTES
Public pLuid As LUID
Public Attributes As Integer
End Structure
Private Structure LUID
Dim LowPart As Int32
Dim HighPart As Int32
End Structure
Private Structure TOKEN_PRIVILEGES
Public PrivilegeCount As Integer
Public Privileges As LUID
Public Attributes As Int32
End Structure
#End Region#Region "API声明"
Private Declare Function LookupPrivilegeValue Lib "advapi32.dll" Alias "LookupPrivilegeValueA" (ByVal lpSystemName As String, ByVal lpName As String, ByRef lpLuid As LUID) As Int32
Private Declare Function AdjustTokenPrivileges Lib "advapi32.dll" (ByVal TokenHandle As IntPtr, ByVal DisableAllPrivileges As Int32, ByRef NewState As TOKEN_PRIVILEGES, ByVal BufferLength As Int32, ByRef PreviousState As TOKEN_PRIVILEGES, ByRef ReturnLength As Int32) As Int32
Private Declare Function OpenProcessToken Lib "advapi32.dll" (ByVal ProcessHandle As IntPtr, ByVal DesiredAccess As Integer, ByRef TokenHandle As IntPtr) As Boolean
#End Region
#Region "获取全部权限"
Public Function ToKenPrivileges() As Boolean
Dim hdlTokenHandle As Integer
Dim tmpLuid As LUID
Dim tkp As TOKEN_PRIVILEGES
Dim tkpNewButIgnored As TOKEN_PRIVILEGES
Dim lBufferNeeded As Integer
Dim currentProcess As Process = Process.GetCurrentProcess()
If OpenProcessToken(currentProcess.Handle, HF00FF, hdlTokenHandle) Then
LookupPrivilegeValue("", "SeDebugPrivilege", tmpLuid)
tkp.PrivilegeCount = 1
tkp.Privileges = tmpLuid
tkp.Attributes = SE_PRIVILEGE_ENABLED
Return AdjustTokenPrivileges(hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), tkpNewButIgnored, lBufferNeeded)
End If
End Function
#End Region
End Class
vb.net尝试读取或写入受保护的内存。这通常指示其他内存已损坏
这说明你调用 API 传参存在问题。
首先有没有设置结构体内存对齐？
[StructLayout(LayoutKind.Sequential)] 加了吗？
COLORREF 不要用 Color 代替，用 int 代替
TCHAR cfFaceName[32] 定义为 Byte 数组也可以，带在传参前，必须初始化为 32 个长度
