But Now I want to delete that key and value from registry entry and for that I am using RegDeleteKey but its giving error 2 which is "The system cannot find the file specified.", can you tell me how can I solve this.

推荐答案

你能显示任何代码吗?它不能帮助这里的任何人缩小您的问题.

Can you show any codes at all? It doesn't help anyone here narrow down your problem.

不过，如果我猜测一下，您在 RegOpenKeyEx 或 RegDeleteKey 中指定 LPCTSTR lpSubKey 的方式有问题.

If I would take a guess though, there's something wrong with the way you have specified LPCTSTR lpSubKey in either RegOpenKeyEx or RegDeleteKey.

示例:

如果您创建了一个密钥:

If you created a key:

HKEY_LOCAL_MACHINE\Software\Test

为了删除它，你需要这样的东西:

In order to delete it, you would need something like this:

RegOpenKeyEx(HKEY_LOCAL_MACHINE, L"Software", 0, KEY_ALL_ACCESS, &RegHandle)
RegDeleteKey(RegHandle, test)

或

RegOpenKeyEx(HKEY_LOCAL_MACHINE, someNullValue, 0, KEY_ALL_ACCESS, &RegHandle)
RegDeleteKey(RegHandle, L"Software\\test")

请务必在 MSDN 上再次检查这些功能.
