IRegistryKey.ReadString

Syntax

ReadString(ValueName: String): String;

Parameters

ValueName - name of the parameter, which value must be obtained.

Description

The ReadString method reads string from string parameter in the registry without checking parameter availability. If the parameter with the ValueName name does not exist, an exception is thrown.

Example

Executing the example requires that the registry subkey HKEY_CURRENT_USER\Software\MyProject\Params contains a string parameter with the Param1 name with a value stored in it.

Sub Main;

Var

RegKey, SubKey: IRegistryKey;

s: String;

Begin

RegKey := RegistryClass.CurrentUser;

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

If SubKey.ValueExists("Param1") Then

s := SubKey.ReadString("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, parameter string value is read into the "s" variable.
