4c51a665c6
Applied patch by snowleopard2 fixing a bunch of typos such as misspellings and double words in the documentation. Combined the patch with some local queued typos waiting to be committed as well as adding new typo fixes inspired by the patch.
Function names with American spelling were not changed nor was third-party code touched. The only code changes involve some changes in strings that are translated ("Can not" -> "Cannot").
Closes #13063 (again).

@class 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:
|
|
|
|
@li @c HKEY_CLASSES_ROOT (HKCR)
|
|
@li @c HKEY_CURRENT_USER (HKCU)
|
|
@li @c HKEY_LOCAL_MACHINE (HKLM)
|
|
@li @c HKEY_CURRENT_CONFIG (HKCC)
|
|
@li @c HKEY_USERS (HKU)
|
|
|
|
After creating a key, it can hold a value. The values can be:
|
|
|
|
@li String Value
|
|
@li Binary Value
|
|
@li DWORD Value
|
|
@li Multi String Value
|
|
@li Expandable String Value
|
|
|
|
@onlyfor{wxmsw}
|
|
|
|
@b Example:
|
|
|
|
@code
|
|
// This assume that the key already exists, use HasSubKey() to check
|
|
// for the key existence if necessary.
|
|
wxRegKey key(wxRegKey::HKLM, "Software\\MyKey");
|
|
|
|
// Create a new value "MyValue" and set it to 12.
|
|
key.SetValue("MyValue", 12);
|
|
|
|
// Read the value back.
|
|
long value;
|
|
key.QueryValue("MyValue", &value);
|
|
wxMessageBox(wxString::Format("%d", value), "Registry Value", wxOK);
|
|
|
|
// Get the number of subkeys and enumerate them.
|
|
size_t subkeys;
|
|
key.GetKeyInfo(&subkeys, NULL, NULL, NULL);
|
|
|
|
wxString key_name;
|
|
key.GetFirstKey(key_name, 1);
|
|
for(int i = 0; i < subkeys; i++)
|
|
{
|
|
wxMessageBox(key_name, "Subkey Name", wxOK);
|
|
key.GetNextKey(key_name, 1);
|
|
}
