IRegistryKey.ReadBoolean

Syntax

ReadBoolean(ValueName: String): Boolean;

Parameters

ValueName. Name of the parameter, which value should be obtained.

Description

The ReadBoolean method reads logic value from the REG_DWORD parameter in the registry. If the ValueName parameter does not exist, an exception is thrown.

Example

Executing the example requires that the registry subkey HKEY_CURRENT_USER\Software\MyProject\Params contains the REG_DWORD parameter with the Param1 name.

Sub Main;

Var

RegKey, SubKey: IRegistryKey;

b: Boolean;

Begin

RegKey := RegistryClass.CurrentUser;

SubKey := RegKey.OpenSubKey("Software\MyProject\Params", False);

If SubKey.ValueExists("Param1") Then

b := SubKey.ReadBoolean("Param1")

End If;

End Sub Main;

After executing the example the Param1 parameter is searched in the registry subkey HKEY_CURRENT_USER\Software\MyProject\Params. If the parameter exists, logical value that is contained in this parameter is read into the "b" variable.
