Detailed Description

Member Enumeration Documentation

WoW64Mode

enum WindowsRegistry::WoW64Mode

These values can be used to specify whether the 32- or 64-bit registry should be used.

When running on a 32-bit OS, there is no 64-bit registry, so the mode will be ignored.

Enumerator
WoW64_Default	Default handling: 32-bit apps will use the 32-bit registry, and 64-bit apps will use the 64-bit registry.
WoW64_64bit	Always use the 64-bit registry store. (KEY_WOW64_64KEY).
WoW64_32bit	Always use the 32-bit registry store. (KEY_WOW64_32KEY).

Member Function Documentation

getValue()

static String JUCE_CALLTYPE WindowsRegistry::getValue ( const String &  regValuePath, const String &  defaultValue = String(), WoW64Mode  mode = WoW64_Default  )

static

Returns a string from the registry.

The path is a string for the entire path of a value in the registry, e.g. "HKEY_CURRENT_USER\Software\foo\bar"

getBinaryValue()

static uint32 JUCE_CALLTYPE WindowsRegistry::getBinaryValue ( const String &  regValuePath, MemoryBlock &  resultData, WoW64Mode  mode = WoW64_Default  )

static

Reads a binary block from the registry.

The path is a string for the entire path of a value in the registry, e.g. "HKEY_CURRENT_USER\Software\foo\bar"

Returns

a DWORD indicating the type of the key.

setValue() [1/4]

static bool JUCE_CALLTYPE WindowsRegistry::setValue ( const String &  regValuePath, const String &  value, WoW64Mode  mode = WoW64_Default  )

static

Sets a registry value as a string.

This will take care of creating any groups needed to get to the given registry value.

setValue() [2/4]

static bool JUCE_CALLTYPE WindowsRegistry::setValue ( const String &  regValuePath, uint32  value, WoW64Mode  mode = WoW64_Default  )

static

Sets a registry value as a DWORD.

This will take care of creating any groups needed to get to the given registry value.

setValue() [3/4]

static bool JUCE_CALLTYPE WindowsRegistry::setValue ( const String &  regValuePath, uint64  value, WoW64Mode  mode = WoW64_Default  )

static

Sets a registry value as a QWORD.

This will take care of creating any groups needed to get to the given registry value.

setValue() [4/4]

static bool JUCE_CALLTYPE WindowsRegistry::setValue ( const String &  regValuePath, const MemoryBlock &  value, WoW64Mode  mode = WoW64_Default  )

static

Sets a registry value as a binary block.

This will take care of creating any groups needed to get to the given registry value.

valueExists()

static bool JUCE_CALLTYPE WindowsRegistry::valueExists ( const String &  regValuePath, WoW64Mode  mode = WoW64_Default  )

static

Returns true if the given value exists in the registry.

keyExists()

static bool JUCE_CALLTYPE WindowsRegistry::keyExists ( const String &  regKeyPath, WoW64Mode  mode = WoW64_Default  )

static

Returns true if the given key exists in the registry.

deleteValue()

static bool JUCE_CALLTYPE WindowsRegistry::deleteValue ( const String &  regValuePath, WoW64Mode  mode = WoW64_Default  )

static

Deletes a registry value.

deleteKey()

static bool JUCE_CALLTYPE WindowsRegistry::deleteKey ( const String &  regKeyPath, WoW64Mode  mode = WoW64_Default  )

static

Deletes a registry key (which is registry-talk for 'folder').

registerFileAssociation()

static bool JUCE_CALLTYPE WindowsRegistry::registerFileAssociation ( const String &  fileExtension, const String &  symbolicDescription, const String &  fullDescription, const File &  targetExecutable, int  iconResourceNumber, bool  registerForCurrentUserOnly, WoW64Mode  mode = WoW64_Default  )

static

Creates a file association in the registry.

This lets you set the executable that should be launched by a given file extension.

Parameters

fileExtension	the file extension to associate, including the initial dot, e.g. ".txt"
symbolicDescription	a space-free short token to identify the file type
fullDescription	a human-readable description of the file type
targetExecutable	the executable that should be launched
iconResourceNumber	the icon that gets displayed for the file type will be found by looking up this resource number in the executable. Pass 0 here to not use an icon
registerForCurrentUserOnly	if false, this will try to register the association for all users (you might not have permission to do this unless running in an installer). If true, it will register the association in HKEY_CURRENT_USER.
mode	the WoW64 mode to use for choosing the database
