注册表操作！！windows2000操作

[kstczzyals]

比如我想更改HKEY_CURRENT_USER\Software\Webzen\Mu\Config
里的一个Resolution子键 REG_DWORD 值是0x0000000
我想通过VC API函数更改为0x00000001
应该怎么做。请帮兄弟写详细一点！！！！！！

Dim hk As Long
RegCreateKey HKEY_CURRENT_USER, "Software\Webzen\Mu\Config", hk
RegSetValueEx hk, "Resolution", 0&, REG_DWORD, &H1&, 4
RegCloseKey hk

呵，为什么把Call errlog注掉了？
帖出来瞧瞧。
