推荐答案

您可以使用 MeasureItem [

You can use the ItemHeight[^] property, but using this property is not trivial (your ComboBox must be owner-drawn). Read the remarks section from the MSDN link for ItemHeight property.

Also check out MeasureItem[^]. This page contains a very useful example for you. ;)

Oh, you CAN set it - and for ListBoxes, too.

Public Const CB_SETITEMHEIGHT = &H153
   Public Const CB_GETITEMHEIGHT = &H154
   Public Const LB_SETITEMHEIGHT = &H1A0
   Public Const LB_GETITEMHEIGHT = &H1A1

使用:SendMessage(handleOfContro，CBxx/LBxx，0，PixelHeightInBytes);

Use: SendMessage(handleOfContro, CBxx/LBxx, 0, PixelHeightInBytes);
