我想知道为什么我的 updateresource 不起作用。它始终是资本，不会更新/替换资源，只会添加一个。
这是我在 VB.NET 中的代码
Imports System.Runtime.InteropServices
Public Class Form1
Private Sub btnStart_Click(sender As Object, e As EventArgs) Handles btnStart.Click
Dim strMiniConfig As String
strMiniConfig = TextBox1.Text
Dim encoder As New System.Text.UnicodeEncoding()
WriteResource("UpdateMyRes.exe", encoder.GetBytes(strMiniConfig))
MsgBox("Resources are now updated.", vbOKOnly + MsgBoxStyle.Information)
End Sub
<DllImport("kernel32.dll", SetLastError:=True, CharSet:=CharSet.Unicode)> _
Private Shared Function UpdateResource(ByVal hUpdate As IntPtr, ByVal lpType As String, ByVal lpName As String, ByVal wLanguage As UShort, ByVal lpData As IntPtr, ByVal cbData As UInteger) As Boolean
End Function
<DllImport("kernel32.dll", SetLastError:=True, CharSet:=CharSet.Unicode)> _
Private Shared Function BeginUpdateResource(ByVal pFileName As String, <MarshalAs(UnmanagedType.Bool)> ByVal bDeleteExistingResources As Boolean) As IntPtr
End Function
<DllImport("kernel32.dll", SetLastError:=True, CharSet:=CharSet.Unicode)> _
Private Shared Function EndUpdateResource(ByVal hUpdate As IntPtr, ByVal fDiscard As Boolean) As Boolean
End Function
Public Function WriteResource(ByVal filename As String, ByVal bytes As Byte()) As Boolean
Try
Dim handle As IntPtr = BeginUpdateResource(filename, False)
Dim file1 As Byte() = bytes
Dim fileptr As IntPtr = ToPtr(file1)
Dim res As Boolean = UpdateResource(handle, "RCData", "CONFIG", 1, fileptr, System.Convert.ToUInt16(file1.Length))
EndUpdateResource(handle, False)
Catch ex As Exception
Return False
End Try
Return True
End Function
Private Function ToPtr(ByVal data As Object) As IntPtr
Dim h As GCHandle = GCHandle.Alloc(data, GCHandleType.Pinned)
Dim ptr As IntPtr
Try
ptr = h.AddrOfPinnedObject()
Finally
h.Free()
End Try
Return ptr
End Function
End Class
这应该替换 RCData\CONFIG 中的资源，但它总是添加名称为 RCDATA\CONFIG 的资源？这是为什么？
这是 C++ 中的相同代码：
WCHAR * newD = L"I am updated resource at the RCData\CONFIG";
HANDLE hUpdate = BeginUpdateResourceW(L"Stub.exe", false);
UpdateResourceW(hUpdate, MAKEINTRESOURCEW(10), L"CONFIG", 1, newD, wcslen(newD)*2);
EndUpdateResource(hUpdate, false);
