当使用“NetApiBufferFree”时，VB6 exe崩溃在win7 [英] VB6 exe crash when is using "NetApiBufferFree" in win7
问题描述
您好，
我在VB6中有一个小应用程序搜索SQL服务器。
I have a little application in VB6 which searchs the SQL servers.
Private Sub getSqlServersWithNetApi（）
On Error GoTo getSqlServersWithNetApi_Error
Dim netStatusRet As Long
Dim entriesread As Long
Dim totalentries As Long
Dim bufptr As Long
Dim level As Long
Dim prefmaxlen As Long
Dim lType As Long
Dim i As Long
Dim sv100 As SERVER_INFO_100
level = 100               '使用SERVER_INFO_100 结构
prefmaxlen = -1
lType = SV_TYPE_SQLSERVER
netStatusRet = NetServerEnum（ByVal 0&，level，bufptr，prefmaxlen，entriesread，totalentries，lType，ByVal 0&，ByVal 0&）
如果netStatusRet = NERR_Success或netStatusRet = ERROR_MORE_DATA则为
   对于i = 0至条目读取 - 1
      RtlMoveMemory sv100，ByVal bufptr，Len（sv100）
      lstSQLServers.AddItem PointerToWStr（sv100.Name）
      bufptr = bufptr + Len（sv100）
   接下来我是
结束如果
NetApiBufferFree bufptr
退出Sub
getSqlServersWithNetApi_Error：
LogError TypeName（Me），" getSqlServersWithNetApi（）"，Err.Description
Private Sub getSqlServersWithNetApi()
On Error GoTo getSqlServersWithNetApi_Error
Dim netStatusRet As Long
Dim entriesread As Long
Dim totalentries As Long
Dim bufptr As Long
Dim level As Long
Dim prefmaxlen As Long
Dim lType As Long
Dim i As Long
Dim sv100 As SERVER_INFO_100
level = 100 ' use SERVER_INFO_100 structures
prefmaxlen = -1
lType = SV_TYPE_SQLSERVER
netStatusRet = NetServerEnum(ByVal 0&, level, bufptr, prefmaxlen, entriesread, totalentries, lType, ByVal 0&, ByVal 0&)
If netStatusRet = NERR_Success Or netStatusRet = ERROR_MORE_DATA Then
For i = 0 To entriesread - 1
RtlMoveMemory sv100, ByVal bufptr, Len(sv100)
lstSQLServers.AddItem PointerToWStr(sv100.Name)
bufptr = bufptr + Len(sv100)
Next i
End If
NetApiBufferFree bufptr
Exit Sub
getSqlServersWithNetApi_Error:
LogError TypeName(Me), "getSqlServersWithNetApi()", Err.Description
End Sub
对于任何操作系统获胜，应用程序工作正常。
For any OS win, the application works fine.
对于OS Win 7，应用程序在"NetApiBufferFree bufptr"行崩溃 - 使用"关闭程序"等。
For OS Win 7, the application crash at line "NetApiBufferFree bufptr" - with "Close the program", etc.
"NetApiBufferFree"已定义
The "NetApiBufferFree" is defined
请你解释一下为什么只发生在Windows 7上？
Could you, please, explain why happend this only for windows 7?
谢谢你，
Gratiela
