C++ (Cpp) RecurseDeleteKeyA Examples

Example #1

File: Register.cpp Project: BuddhismZhang/weasel

void UnregisterServer()
{
	char achIMEKey[ARRAYSIZE(c_szInfoKeyPrefix) + CLSID_STRLEN];
	if (!CLSIDToStringA(c_clsidTextService, achIMEKey + ARRAYSIZE(c_szInfoKeyPrefix) - 1))
		return;
	memcpy(achIMEKey, c_szInfoKeyPrefix, sizeof(c_szInfoKeyPrefix) - 1);
	RecurseDeleteKeyA(HKEY_CLASSES_ROOT, achIMEKey);

	// On Windows 8, we need to manually delete the registry key for our TIP
	char tipKey[ARRAYSIZE(c_szTipKeyPrefix) + CLSID_STRLEN];
	if (!CLSIDToStringA(c_clsidTextService, tipKey + ARRAYSIZE(c_szTipKeyPrefix) - 1))
		return;
	memcpy(tipKey, c_szTipKeyPrefix, sizeof(c_szTipKeyPrefix) - 1);
	RecurseDeleteKeyA(HKEY_CLASSES_ROOT, tipKey);
}

	RecurseDeleteKeyA(HKEY_CLASSES_ROOT, achIMEKey);
}
