1.求在VB中修改注册表的代码

2.C++修改注册表键值的问题

3.工行u盾驱动是怎么回事？急急········

5.在C语言中加什么代码使程序开机运行

错误写入注册表键regsetvalue ex代码5怎么解决_

再一次帖出这个注册表操作通用函数如果楼主用到就用用不到就算了~~~

我已经怕了RegQueryValue了

求在VB中修改注册表的代码

问题是RegDeleteValue的最后一次虽然成功执行，但返回值却是2，导致程序退出。是不是？你可以对返回值的判断语句改一下，如：

if(info!=ERROR_SUCCESS && info != ERROR_FILE_NOT_FOUND)

ERROR_FILE_NOT_FOUND即是2号错误啦，字面意思是没有找到文件错误。if中的&&表示如果info不等于ERROR_SUCCESS同时info不等于ERROR_FILE_NOT_FOUND，就进入if内部执行，因为这里的代码没有错，RegDeleteValue函数成功执行时为什么返回2而不是0，这无从知道，可能内部发生了什么错误，我猜想。如果不想让程序退出只能添加if的后半部分了。这可以算是没有办法的办法吧。

工行u盾驱动是怎么回事？急急········

写入一个 DWORD 要什么 strVal，又不是字符串。

DWORD dwValue = 0;

RegSetValueEx(hKey, _T("ProxyEnable"),0, REG_DWORD, (BYTE*)&dwValue, sizeof(DWORD));

不过你这方法还是过于繁琐，这么多步骤用一行就能解决：

DWORD dwValue = 0;

SHSetValue(HKEY_CURRENT_USER, _T("Software\\Microsoft\\Windows\\Internet Settings"), _T("ProxyEnable"), REG_DWORD, &dwValue, sizeof(DWORD));
