ReadBoolean(ValueName: String): Boolean;
ValueName. Name of the parameter, which value should be obtained.
The ReadBoolean method reads logical value from the REG_DWORD parameter in the registry without checking parameter availability.
If the ValueName parameter does not exist, an exception is thrown.
Executing the example requires that the registry subkey [HKEY_CURRENT_USER\Software\MyProject\Params] contains the REG_DWORD parameter with the Param1 name.
Add a link to the Registry system assembly.
Sub UserProc;
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 UserProc;
After executing the example the Param1 parameter is searched in the specified registry subkey. If the parameter exists, logical value that is contained in this parameter is read into the "b" variable.
