Detailed Description

A class to encapsulate the access to the Windows registry.

Vocabulary :

• Key : Node of the registry (kind of "directory").
• Value_Name : Name of a value in a key.
• Value : Value of the Value_Name.

This class is defined for all operating systems. So, it is possible to use it everywhere without complicated conditional compilation. However, all calls return an error on non-Windows systems.

GetValue()

static UString ts::Registry::GetValue ( const UString &  key, const UString &  value_name = UString(), Report &  report = (*(static_cast< ts::Report * >(ts::NullReport::Instance())))  )

static

Get a value in a registry key as a string.

Parameters

[in]	key	Registry key.
[in]	value_name	Name of the value in key.
[in,out]	report	Where to report error.

Returns

An empty string if non-existent or error.

SetValue() [1/2]

static bool ts::Registry::SetValue ( const UString &  key, const UString &  value_name, const UString &  value, bool  expandable = false, Report &  report = (*(static_cast< ts::Report * >(ts::NullReport::Instance())))  )

static

Set the value of a registry key.

Parameters

[in]	key	Registry key.
[in]	value_name	Name of the value in key.
[in]	value	Value to set in value_name.
[in]	expandable	If true, set the type to REG_EXPAND_SZ. Otherwise, set type to REG_SZ.
[in,out]	report	Where to report error.

Returns

True on success, false on error.

SetValue() [2/2]

static bool ts::Registry::SetValue ( const UString &  key, const UString &  value_name, uint32_t  value, Report &  report = (*(static_cast< ts::Report * >(ts::NullReport::Instance())))  )

static

[in]	value_name	Name of the value in key.
[in]	value	Value to set in value_name. Set the data type as REG_DWORD.
[in,out]	report	Where to report error.

Returns

True on success, false on error.
