IRegistryKey.ReadInteger

Syntax

ReadInteger(ValueName: String): Integer;

Parameters

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

Description

The ReadInteger method reads integer value from the REG_DWORD parameter in the registry without checking parameter availability. 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 with an integer number stored in it.

Sub Main;

Var

RegKey, SubKey: IRegistryKey;

i: Integer;

Begin

RegKey := RegistryClass.CurrentUser;

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

If SubKey.ValueExists("Param1") Then

i := SubKey.ReadInteger("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, the integer number that is contained in this parameter is read into the "i" variable.
