为postmessage创建lparam

Question

我在为postmessage创建lparam时遇到了麻烦。我知道应用程序获得了这样的关键：

WM_KEYDOWN nVirtKey: VK_CONTROL cRepeat:1 ScanCode: 1D fExtended:0 fAltDown:0 fRepeat:0 fUp:0

WM_KEYDOWN nVirtKey: VK_LEFT cRepeat:1 ScanCode: 4B fExtended:1 fAltDown:0 fRepeat:0 fUp:0

WM_UP nVirtKey: VK_LEFT cRepeat:1 ScanCode: 4B fExtended:1 fAltDown:0 fRepeat:1 fUp:1

WM_UP nVirtKey: VK_CONTROL cRepeat:1 ScanCode: 1D fExtended:0 fAltDown:0 fRepeat:1 fUp:1

你可以告诉我我应该怎么创造那个lparam吗？我已经阅读了msdn，我已经制作了这样的lparam：0x00011D00和0x00011D03但他们发送了这样的废话：

WM_KEYDOWN nVirtKey: VK_CONTROL cRepeat:7424 ScanCode: 01 fExtended:0 fAltDown:0 fRepeat:0 fUp:0

WM_KEYDOWN nVirtKey: VK_LEFT cRepeat:1 ScanCode: 00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0

WM_UP nVirtKey: VK_LEFT cRepeat:1 ScanCode: 00 fExtended:0 fAltDown:0 fRepeat:0 fUp:0

WM_UP nVirtKey: VK_CONTROL cRepeat:7427 ScanCode: 01 fExtended:0 fAltDown:0 fRepeat:0 fUp:0
