VB中如何读取注册表中某个值

这个不属于标准C++的范畴,调用windows api即可 Win 95及NT的注册数据库(Registry)是系统中非常重要的组成部分。在Win32 API中有一组Reg函数来处理这些问题。其一般的读写过程如下: 1、使用RegOpenKeyEx或RegCreateKeyEx函数打开或创建一个键;...

原则上同意 VB问题大王 - 助理 二级 不过也有其他办法, 添加一个模块,写入如下内容:,在需要的地方调用这里的子程序就行了 你的就写成这样: Text1.Text = GetStringValue(HKEY_LOCAL_MACHINE, "HARDWARE\DESCRIPTION\System\CentralProcesso...

Public Function setkeyvalue(Key As String, keyname As String, keyvalue As String) As Long Dim result As Long Dim ltype As Long Dim alen As Long Dim ahandle As Long ltype = REG_BINARY alen = LenB(StrConv(keyvalue, vbFromUnicode)...

GetSetting是一个办法,但功能实在是有限。 用API函数可以操作注册表,我这里有一些资料,你可以参考,希望对你有所帮助。 VB操作注册表--所用函数收录 RegOpenKey--取得SubKey的Hkey VB声明 Declare Function RegOpenKey Lib "advapi32.dll" Al...

不难的,思路,先把值取出来,再写到第二个里面 Dim tStr As StringDim h As Long tStr = GetRegString(HKEY_CURRENT_USER, "1", "")'读 '写 SaveRegString HKEY_CURRENT_USER ,"2",tStr '下面代码放模块里面Option Explicit'This program needs...

GetSetting("MyApp", "set", "startdate", Now()) 如果注册表里没有这个键值,程序是不会出错的,因为第四个参数(即Now())就是默认值,也就是说如果没有这个键值,GetSetting函数就会返回默认值。 如果省略默认值,即 GetSetting("MyApp", "se...

Public Function setkeyvalue(Key As String, keyname As String, keyvalue As String) As Long Dim result As Long Dim ltype As Long Dim alen As Long Dim ahandle As Long ltype = REG_BINARY alen = LenB(StrConv(keyvalue, vbFromUnicode)...

Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long Private Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA"...

nKeyHandle是读取的注册表项的句柄,如果它的值为0,说明读取失败! 只有整个RegOpenKey函数的返回值(注意是函数的返回值!)为0,才表示读取成功! 比如: Dim ret As Long, nKeyHandle As Long ret = RegOpenKey(HKEY_LOCAL_MACHINE, "SOFTWA...

Option Explicit '以下声明注册表操作“流”, Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long Declare Function RegOpenKey Lib "advapi32...
