WinBinder Manual/wb set registry key

wb_set_registry_key writes a string or integer value to the Windows registry.

Syntax

bool wb_set_registry_key (string key, string subkey [, string entry [, mixed value]])

• Together, key, subkey and entry reference a value in the Windows registry.
• If the value does not exist, the function creates it.

• key can be one of the following values:
  • "HKCU" or "HKEY_CURRENT_USER"
  • "HKLM" or "HKEY_LOCAL_MACHINE"
  • "HKCR" or "HKEY_CLASSES_ROOT"
  • "HKU" or "HKEY_USERS"
  • "HKCC" or "HKEY_CURRENT_CONFIG"
  • "HKD" or "HKEY_DYN_DATA"

• subkey may contain forward or reverse slashes.

• If entry is an empty string, a NULL value or is not supplied, the function sets the default value for the subkey.

• value may be a string, an integer or a floating-point type; if value is NULL, the entry is deleted.

NOTE: Registry keys, subkeys and entries are case-insensitive.

Example

// Creates or sets various values

wb_set_registry_key("HKCU", "Software\\WinBinder", "String value", "1234");
wb_set_registry_key("HKCU", "Software\\WinBinder", "Integer value", 1234);
wb_set_registry_key("HKCU", "Software\\WinBinder", "Floating-point value", 1.234);
wb_set_registry_key("HKCU", "Software\\WinBinder", "", "The default");

// Delete the new entries

wb_set_registry_key("HKCU", "Software\\WinBinder", "String value", null);
wb_set_registry_key("HKCU", "Software\\WinBinder", "Integer value");
wb_set_registry_key("HKCU", "Software\\WinBinder", "Floating-point value");
wb_set_registry_key("HKCU", "Software\\WinBinder", "");
