Usually things like Google apps (apps or libraries) tend to have forums for their users to interact and ask questions, have you looked to see if such forum exists? You may have better luck with people who have used that specific API there.
I have a multi threaded MFC exe built with all its basic classes including CSocket, with TCP connection through mainframe etc. , I want to split it to two different components. ATL service and MFC GUI. Can I do it and can I use the MFC classes in the ATL service.
Thanks in advance,
hello guys... Is it possible to encrypt voice just like we can encrypt data. Encryption methodology can be any like: reversing the voice. For example, If I speak hello then I want it to be converted to olleh. Thnx
This world is going to explode due to international politics, SOON.
You can encrypt any bit stream using the various libraries available for the purpose. To do what you are asking would require analysis of the stream and separation at each character of each word, which is impossible in spoken sounds.
Try saying "hello" with different stresses and see if you can determine the exact point where each letter starts and ends; do you hear one or two 'l's?
As long as the data is digitized (using PCM or some other encoding technique) it can be encrypted. Speech recognition is a completely different issue, and quite frankly I would advice you to not try to do that at this point (that's a pretty involved task). I would start with:
0. Learn how to turn voice into digital data using PCM (learn capture and playback techniques).
1. Learn how to use encryption (using a library is the fastest method).
This is a callback function definition used in capAVI frame callback.
The LPVIDEOHDR structure supplies useful data and one of the members ( dwUser) can be user defined. Is there a way to set this before the system executes this callback?
Could someone point me to a sample code which actually uses this member in any capAVI callbacks.
There is a MFC-Based Application，his window tree structure as below:
Root Parent Window
Sub-Parent Window3：ListCtrl、Progress Bar
Sub-Parent Window4：Check Box
I want to know if user click any window(including controls) or Get Focus，which message can Root parent window receive.
Since you are using nonstandard nomenclature, please define Root Window, Sub window and Child window. What is relationship between all windows?
In general message about gaining focus (by any means including mouse click) is sent to a window that is gaining focus and loosing focus.
If this window is a child window, the parent does not know about what child gained focus.
You have two choices: write code in the child window to notify parent window about gaining focus using custom defined message, or write windows hook that will receive messages before any window does and post a message from the hook procedure to a parent window.
In both cases you would pass a handle to a window that gains focus.
