For example, the timeout does not keep counting down while the computer is asleep. The input types for which an input event object handle will be added to the array of object handles.

This parameter can be one or more of the following values. This value is cleared when you call GetMessage or PeekMessage without filtering messages. This value is cleared when you call GetMessage or PeekMessage , whether or not you are filtering messages.

If the function succeeds, the return value indicates the event that caused the function to return. It can be one of the following values. This value is also returned upon the occurrence of a system event that requires the thread's action, such as foreground activation.

If the conditions have not been met, the calling thread enters the wait state until the conditions of the wait criteria have been met or the time-out interval elapses. When dwFlags is zero, this function checks the handles in the array in order starting with index 0, until one of the objects is signaled. If multiple objects become signaled, the function returns the index of the first handle in the array whose object was signaled.

This is because functions such as PeekMessage , GetMessage , GetQueueStatus , and WaitMessage check the queue and then change the state information for the queue so that the input is no longer considered new. If this flag is not used, the existing unread input received prior to the last time the thread checked the queue is ignored. The function modifies the state of some types of synchronization objects. Modification occurs only for the object or objects whose signaled state caused the function to return.

For example, the system decreases the count of a semaphore object by one. For more information, see the documentation for the individual synchronization objects. Synchronization Functions.

I have simple function in my appliction that just launches a setup. The problem is in the do-while loop shown below. It seems like the my application gets stuck inside the loop.

The setup. Is there something different with messenging in Vista? I am out of ideas. The content you requested has been removed. Ask a question. Quick access. Search related threads. Remove From My Forums.
