registry editing

[Guest_imported]

I need to edit a registry key in my registry using a console application. I tried searching microsoft for "registry", but didn't find scripts.

Creating or Opening a Registry Key

Before you can read or write to a key, you must first obtain a handle to it. To do this, use either the RegOpenRegKeyEx or RegCreateKeyEx Microsoft Win32® functions. In practice, you will almost always use RegCreateKeyEx, which will open the key if it exists or create it if it does not. Here is a typical scenario:

Declare an HKEY variable in your code.
Call RegCreateKeyEx, passing HKEY_LOCAL_MACHINE as the parent key and Software/YourCompany/YourApplication as the subkey.
For each setting you wish to read, call RegQueryValueEx, and if the setting is not found set a default value.
Close the handle to the key with RegCloseKey.
Sample code:


void CMyFirstMFCApplicationApp::LoadPreferences()
{
HKEY hkey;
DWORD dwDisposition;

DWORD dwType, dwSize;

// Set the default values
m_dwMaxFileSize = 16 * 1024; // 16k
_tcscpy(m_szLastFileName, TEXT("Datafile.TXT&quot);

if(RegCreateKeyEx(HKEY_LOCAL_MACHINE, TEXT("Software\\My Company\\My
Application&quot, 0, NULL, 0, 0, NULL, &hkey, &dwDisposition)==
ERROR_SUCCESS)
{
dwType = REG_DWORD;
dwSize = sizeof(DWORD);
RegQueryValueEx(hkey, TEXT("MaxFileSize&quot, NULL, &dwType,
(PBYTE)&m_dwMaxFileSize, &dwSize);

dwType = REG_SZ;
dwSize = sizeof(m_szLastFileName);
RegQueryValueEx(hkey, TEXT("LastFileName&quot, NULL, &dwType,
(PBYTE)&m_szLastFileName, &dwSize);

RegCloseKey(hkey);
}
}


void CMyFirstMFCApplicationApp::SavePreferences()
{
HKEY hkey;
DWORD dwDisposition;

DWORD dwType, dwSize;

if(RegCreateKeyEx(HKEY_LOCAL_MACHINE, TEXT("Software\\My Company\\My
Application&quot, 0, NULL, 0, 0, NULL, &hkey, &dwDisposition)==
ERROR_SUCCESS)
{
dwType = REG_DWORD;
dwSize = sizeof(DWORD);
RegSetValueEx(hkey, TEXT("MaxFileSize&quot, 0, dwType,
(PBYTE)&m_dwMaxFileSize, dwSize);

dwType = REG_SZ;
dwSize = (_tcslen(m_szLastFileName) + 1) * sizeof(TCHAR);
RegSetValueEx(hkey, TEXT("LastFileName&quot, 0, dwType,
(PBYTE)&m_szLastFileName, dwSize);

RegCloseKey(hkey);
}
}

I don't get it at all. Can you maybe edit that code a little bit (making the areas I need to edit italic)? And, I will need to make that file edit hkey_local_machine/somecrap/file

Here is what I did (the bold areas are what I edited):

void CMyFirstMFCApplicationApp::LoadPreferences()
{
HKEY hkey;
DWORD dwDisposition;

DWORD dwType, dwSize;

// Set the default values
m_dwMaxFileSize = 16 * 1024; // 16k
_tcscpy(m_szLastFileName, TEXT("Datafile.TXT&quot);

if(RegCreateKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Logitech\\MouseWare\\CurrentVersion\\Control Center\\Schemes\\.Default\\Devices\\Cordless6\\0001\\Assignments\\MiddleMouseShortClick\\AutoScroll\\ScrollCompatibility&quot, 0, NULL, 0, 0, NULL, &hkey, &dwDisposition)==
ERROR_SUCCESS)
{
dwType = REG_DWORD;
dwSize = sizeof(DWORD);
RegQueryValueEx(hkey, TEXT("MaxFileSize&quot, NULL, &dwType,
(PBYTE)&m_dwMaxFileSize, &dwSize);

dwType = REG_SZ;
dwSize = sizeof(m_szLastFileName);
RegQueryValueEx(hkey, TEXT("2&quot, NULL, &dwType,
(PBYTE)&m_szLastFileName, &dwSize);

RegCloseKey(hkey);
}
}


void CMyFirstMFCApplicationApp::LoadPreferences()
{
HKEY hkey;
DWORD dwDisposition;

DWORD dwType, dwSize;

// Set the default values
m_dwMaxFileSize = 16 * 1024; // 16k
_tcscpy(m_szLastFileName, TEXT("Datafile.TXT&quot);

if(RegCreateKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Logitech\\MouseWare\\CurrentVersion\\Control Center\\Schemes\\.Default\\Devices\\Cordless6\\0001\\MacSets\\AutoScroll\\ScrollCompatibility&quot, 0, NULL, 0, 0, NULL, &hkey, &dwDisposition)==
ERROR_SUCCESS)
{
dwType = REG_DWORD;
dwSize = sizeof(DWORD);
RegQueryValueEx(hkey, TEXT("MaxFileSize&quot, NULL, &dwType,
(PBYTE)&m_dwMaxFileSize, &dwSize);

dwType = REG_SZ;
dwSize = sizeof(m_szLastFileName);
RegQueryValueEx(hkey, TEXT("2&quot, NULL, &dwType,
(PBYTE)&m_szLastFileName, &dwSize);

RegCloseKey(hkey);
}
}


void CMyFirstMFCApplicationApp::LoadPreferences()
{
HKEY hkey;
DWORD dwDisposition;

DWORD dwType, dwSize;

// Set the default values
m_dwMaxFileSize = 16 * 1024; // 16k
_tcscpy(m_szLastFileName, TEXT("Datafile.TXT&quot);

if(RegCreateKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Logitech\\MouseWare\\CurrentVersion\\Control Center\\Schemes\\.Default\\MacSets\\DoubleM\\AutoScroll\\ScrollCompatibility&quot, 0, NULL, 0, 0, NULL, &hkey, &dwDisposition)==
ERROR_SUCCESS)
{
dwType = REG_DWORD;
dwSize = sizeof(DWORD);
RegQueryValueEx(hkey, TEXT("MaxFileSize&quot, NULL, &dwType,
(PBYTE)&m_dwMaxFileSize, &dwSize);

dwType = REG_SZ;
dwSize = sizeof(m_szLastFileName);
RegQueryValueEx(hkey, TEXT("2&quot, NULL, &dwType,
(PBYTE)&m_szLastFileName, &dwSize);

RegCloseKey(hkey);
}
}

Yeah, I saw it. But will my script work?

Okay, there are fifty errors. Can you fix it (I can't fix a script I have never worked with)?

what was the errors ?
can u use another language ? so much code so 'simple' task
what other language do u use ?
what do u what exactly ? create one , delete one , read one?
&quot;I can't fix a script I have never worked with&quot;
i didn't work with it either ---------------------------------------

It is supposed to edit three registry valus.

[winsoc]

can you include the whole code, including all required libraries please.

thanks
