Creates a key in the Windows registry.
// Create the "HKEY_LOCAL_MACHINE\SOFTWARE\MyApp" key
ResCreateKey = RegistryCreateKey("HKEY_LOCAL_MACHINE\SOFTWARE\MyApp")
Syntax
<Result> = RegistryCreateKey(<Key Path>)
<Result>: Boolean
  • True if the key was created,
  • False otherwise.
The key is not modified if it already exists: RegistryCreateKey returns False and the ErrorOccurred variable is set to False.
<Key Path>: Character string (with quotes)
Full path of key to create.
Remarks

Creating a key

  • The key creation is recursive: if the directories specified in <Key Path> do not exist, they are automatically created in the registry.
  • Only secondary keys can be created (no primary key can be created).

32-bit application operating on a 64-bit system

On a 64-bit system, the 32-bit applications write into the registry from the following branch:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node
WEBDEV - Server code

Handling the registry in Windows Vista

In Windows Vista (and later), if the UAC mechanism is enabled, you must have the administrator rights to write into "HKEY_LOCAL_MACHINE\SOFTWARE".
If the user does not have the necessary rights, the UAC mechanism performs a redirection to "HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE". The purpose of this redirection is to ensure the compatibility of the applications. The keys written in this directory can be read by the application that has written them.
Reminder: when creating the executable, a manifest can be included in the executable so that administrator rights are granted to the application.

//Criar se nao existe a Pasta System
IF ResExist1 = True AND ResExist2 = False THEN
//cria a pasta da esquerda
RegistryCreateKey("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System")
//cria a chave DisableTaskMgr tipo DWORD 32 dentro da Pasta
RegistrySetValue("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System","DisableTaskMgr",0)
END

if bEnableDisable = false
RegistrySetValue("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System","DisableTaskMgr",1) //disable

else

RegistrySetValue("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System","DisableTaskMgr",0) //enable
