They typically only supply the number of bytes in the <b>dmSize</b> member of <b>DEVMODE</b>. The number of bytes to be allocated should be the sum of <b>dmSize</b> + <b>dmDriverExtra</b>. When a call is made to the <a href="https://docs.microsoft.com/windows/desktop/api/wingdi/nf-wingdi-createdca">CreateDC</a> function with an incorrect target device, the printer driver tries to access the additional bytes and unpredictable results can occur. To help protect against a crash and make the additional bytes available, OLE pads the size of OLE 2 target devices created from OLE 1 target devices.</remarks>
