C++ 将字符串(REG#u SZ)值写入C+中的注册表+;

C++ 将字符串(REG#u SZ)值写入C+中的注册表+;,c++,registry,C++,Registry,我已经有了将值写入windows注册表的大部分代码,但是当我将路径更改为一个伪键时,我为测试它而设置的值失败了。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) {

我已经有了将值写入windows注册表的大部分代码,但是当我将路径更改为一个伪键时,我为测试它而设置的值失败了。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 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.");
    }
所有三个测试都会产生错误状态

让我困惑的是,当我将代码指向注册表的其他部分时,我能够运行这段代码。有什么想法吗

谢谢,
布莱恩,我觉得自己很傻。解决方案是需要按如下方式正确转义字符串中的斜杠:

LPCTSTR sk = TEXT("SOFTWARE\\TestSoftware");
希望有人会觉得这很有用……

HKEY OpenKey(HKEY hRootKey,char*strKey)

void SetintVal(HKEY hKey, LPCTSTR lpValue, DWORD data)
{

  if (nError==ERROR_FILE_NOT_FOUND)
     data = 0; 
  SetVal() is called.
  else if (nError)

  return data;

}
{ HKEY HKEY; LONG nError=RegOpenKeyEx(hRootKey、strKey、NULL、KEY\u ALL\u ACCESS和hKey); 如果(错误==找不到错误文件) {
cout对于
UNICODE
环境:

//Writing to registry
HKEY hKey;
LPCTSTR sk = TEXT("SOFTWARE\\Microsoft\\Windows");

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("Sample");
WCHAR path[80] = TEXT("C:\\samples\\app.exe");

LONG setRes = RegSetValueEx(hKey, value, 0, REG_SZ, (LPBYTE)path, sizeof(path));

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.");
}

请注意,
RegSetValueEx
函数以字节(而非字符)为单位获取字符串长度因此,您最好使用<代码> StutcCbLimeS/<代码>,而不是<代码> StLeN<代码>。请直接编辑您以前的代码,而不是发布第二个问题的答案。请考虑编辑您的答案,包括解释您的代码是如何解决手头的问题的。或者,从VC++ 2013开始:< COD。e> LR“(“软件\测试软件”)”
这些被称为原始字符串文字。虽然
sizeof(path)
肯定足够大,但我相信您想要的不是
sizeof(path)
而是
wcslen(path)*sizeof(WCHAR)
。这也足以容纳整个字符串。在我的代码中,我将
LPCWSTR I\u lpStringValue
传递给我的函数,并使用
wcslen(I\u lpStringValue)*sizeof(wchar\u t)
用于
RegSetValueEx
函数的
cbData
参数。它似乎保存了所有字符。如果我有误解,请随时更正。
