information under this root key is not placed in the registry.4 Permissions to access the registrySometimes the following error occurs when the program executes, such as the following code:LONG X1 =regcreatekey (Hkey_local_machine,text ("Software\\vc++mfc\\adminss"), hkey);After running X1 = 5, the corresponding error message is "Access Denied". Of course, this program does not create a key in the registry after the reason is that the previous said t

Here we look at the use of these five interface functions: First, create key RegCreateKeyEx You can create a key in the registry by using the RegCreateKeyEx function, and if the key you want to create already exists, open the key. The function prototype is as follows: LONG

This article from http://www.vckbase.com/document/viewdoc? Id = 645 For ease of use, I have written some operations as functions for convenient calling. The specific code is as follows: I. Definition Hkey; char content [256]; // DWORD dwtype = REG_SZ; // defines the data read type DWORD dwlength = 256; struct hkey _ * rootkey; // registry primary key name tchar * subkey; // the address of the registry key

Recently, it is necessary to operate the Registry in a self-written program. I would like to sum up some experience and make a demo for future use. Now I will share it with you... For ease of use, some operations are written as functions for convenient calling. The specific code is as follows: I. Definition Hkey; char content [256]; // DWORD dwtype = REG_SZ; // defines the data read type DWORD dwlength = 256; struct

. HKEY_CLASSES_USER is the information used for the current (LOGIN) user. HKEY_CURRENT_CONFIG contains information about the current system configuration.

Recently, when I was working on a project, I used some functions that operate the Registry. Now I want to record these functions for future use. 1. Open the registry key long regopenkeyex (hkey, // handle to open key primary key lpctstr lpsubkey, // subkey name subkey DWORD uloptions, // reserved.
