PostVirtualKeyEvent
- 0 2.0
Posts a virtual key-code event to Windows.
PostVirtualKeyEvent( UINT vk, BOOL fUp )
Parameters
Virtual key. This argument takes a Windows VK_ constant as defined in the
WINDOWS.H include file. Depending on the key, this is either the key scan code or
the ASCII equivalent to represent a character key. For example, VK_A has the
value "A."
fUp
Key-transition flag. This parameter should be FALSE to specify that the key is
down or TRUE to specify that it is up.
Return Value
This function does not return a value.
Comments
PostVirtualKeyEvent does not check the virtual key code for errors.
Normally, an application should follow a key-down message with a corresponding
key-up message to accurately simulate the actual events from the keyboard. You
can post repeating keys by calling PostVirtualKeyEvent consecutively, one call per repeat, with fUp set to FALSE. End the sequence with a single call to PostVirtualKeyEvent with fUp set to TRUE.
The events are posted to the system message queue. The application with the
input focus can receive the messages by calling the Windows GetMessage or PeekMessage function.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
