\section{\class{wxRegKey}}\label{wxregkey}
|
|
|
|
wxRegKey is a class representing the Windows registry (it is only available
|
|
under Windows). One can create, query and delete registry keys using this
|
|
class.
|
|
|
|
The Windows registry is easy to understand. There are five registry keys,
|
|
namely:
|
|
|
|
\begin{enumerate}\itemsep=0pt
|
|
\item HKEY\_CLASSES\_ROOT (HKCR)
|
|
\item HKEY\_CURRENT\_USER (HKCU)
|
|
\item HKEY\_LOCAL\_MACHINE (HKLM)
|
|
\item HKEY\_CURRENT\_CONFIG (HKCC)
|
|
\item HKEY\_USERS (HKU)
|
|
\end{enumerate}
|
|
|
|
After creating a key, it can hold a value. The values can be:
|
|
|
|
\begin{enumerate}\itemsep=0pt
|
|
\item String Value
|
|
\item Binary Value
|
|
\item DWORD Value
|
|
\item Multi String Value
|
|
\item Expandable String Value
|
|
\end{enumerate}

if( !pRegKey->Exists() )
|
|
pRegKey->Create();
|
|
|
|
//will create a new value MYVALUE and set it to 12
