在C ++中将字符串（REG_SZ）值写入注册表 [英] Writing string (REG_SZ) values to the registry in C++

问题描述

我有大部分的代码写入一个值到Windows注册表，但是当我将路径更改为一个虚拟键和值，我设置为测试失败。我的代码如下：

  HKEY hKey; 
 LPCTSTR sk = TEXT（SOFTWARE\TestSoftware）; 
 
 LONG openRes = RegOpenKeyEx（HKEY_LOCAL_MACHINE，sk，0，KEY_ALL_ACCESS，& hKey）; 
 
 if（openRes == ERROR_SUCCESS）{
 printf（Success opening key。）; 
} else {
 printf（Error opening key。）; 
} 
 
 LPCTSTR值= TEXT（TestSoftwareKey）; 
 LPCTSTR data =TestData\0; 
 
 LONG setRes = RegSetValueEx（hKey，value，0，REG_SZ，（LPBYTE）data，strlen（data）+1）; 
 
 if（setRes == ERROR_SUCCESS）{
 printf（Success writing to Registry。）; 
} else {
 printf（Write to Registry。）; 
} 
 
 LONG closeOut = RegCloseKey（hKey）; 
 
 if（closeOut == ERROR_SUCCESS）{
 printf（Success closing key。）; 
} else {
 printf（Error closing key。）; 
} 
  

这三个测试都会产生错误状态。

令我困惑的部分是，我能够在将其指向注册表的其他部分时运行此代码。任何想法？

感谢，

解决方案

我觉得很蠢。解决方案是，需要正确转义字符串中的斜杠，如下所示：

  LPCTSTR sk = TEXT（SOFTWARE\\\ \\ TESTSoftware）;希望有人发现这有用... 
I've got most of the code for writing a value to the windows registry, however when I change the path to a dummy key and value that I've set up for testing it fails.  My code is below:
    HKEY hKey;
    LPCTSTR sk = TEXT("SOFTWARE\TestSoftware");

    LONG openRes = RegOpenKeyEx(HKEY_LOCAL_MACHINE, sk, 0, KEY_ALL_ACCESS , &hKey);

    if (openRes==ERROR_SUCCESS) {
    	printf("Success opening key.");
    } else {
    	printf("Error opening key.");
    }

    LPCTSTR value = TEXT("TestSoftwareKey");
    LPCTSTR data = "TestData\0";

    LONG setRes = RegSetValueEx (hKey, value, 0, REG_SZ, (LPBYTE)data, strlen(data)+1);

    if (setRes == ERROR_SUCCESS) {
    	printf("Success writing to Registry.");
    } else {
    	printf("Error writing to Registry.");
    }

    LONG closeOut = RegCloseKey(hKey);

    if (closeOut == ERROR_SUCCESS) {
    	printf("Success closing key.");
    } else {
    	printf("Error closing key.");
    }
All three tests yield error statuses.

The part that confuses me is that I was able to run this code when pointing it at other portions of the registry.  Any ideas?

thanks,
brian
解决方案
I feel silly.  The solution is that need to properly escape the slash in the string as follows:
LPCTSTR sk = TEXT("SOFTWARE\\TestSoftware");
Hopefully someone finds this useful...
