Hi All,
once I was assigned in a project which is concerned with some streaming to the clients connected. anyway I have implemented a single server - multi client system which can be used for stream video from the server to the number of clients connected. Initially the clients were showing the video very slowly (even if there's only one client connected) in an 100 mbps network. the frames are send in compressed jpg format (around 70%). Now I have came out from that project. now some other person working on that for the performance improvement of server client system. ( when I was there, this feature was in not included in the first phase so I escaped ) that story over.
When I worked with remote deskop of Windows XP, I really get impressed because of the peformance hit I had in my system. anybody can give some inputs to make sure that, the network transfer is optimum and how to improves the streaming across?

I think the color depths is scaled down to 256 colors to minimize data. (->Citrix)
Another possible optimization can be to only transport parts of the client which had changed recently. It leeds to compression schemes as mpeg.
I hope it helps.

How do I send keys to application?
I tried like
::SendMessage(hwnd,WM_CHAR,(WPARM)VK_KEY,NULL)
But it's not right I guess.. please help me.
NULL

sendInput doesn't take Hwnd as a param so is it not possible to specify the window? and hence you said "The window must have focus" ?
NULL

Yes it's not possible to specify a window as it's simulating keys at the lowest level. You would have to set the window as the foreground window.
Raymond talks about this. You can also read the comments for more good info.

Using PostMessage with WM_KEYDOWN / WM_KEYUP / WM_SYSKEYDOWN / WM_SYSKEYUP (WM_CHAR is generated by the TranslateMessage function) might work with a number of applications though (there's that problem with key states though). You would have to test with all the applications you wish to send input to if you would like to still continue with this route.

then First SetFocus on window and then send Keyinput to that window. Is setting focus on That window incurred any problem?

I haven't tried that yet. There must be no problem in setting the focus. But still I'd try to do it with a sendMessage.

then Simulate KeyPress by sending WM_KEYDOWN and WM_KEYUP message one after another!

hi,
Assuming m_pWnd is pointer to the window you want to send keys then use,
m_pWnd->SendMessage(WM_KEYDOWN,WPARAM(VK_DELETE),LPARAM(0x01530001));<br />
m_pWnd->SendMessage(WM_KEYUP,WPARAM(VK_DELETE),LPARAM(0xC1530001));
or
::SendMessage(hwnd,WM_KEYDOWN,WPARAM(VK_DELETE),LPARAM(0x01530001));<br />
::SendMessage(hwnd,WM_KEYUP,WPARAM(VK_DELETE),LPARAM(0xC1530001));
if this answers you then, vote for 5

What's being stored in LPARAM here? Can you explain a bit?
NULL

|
|
|
|
what If I'd do the try the same with VK_F1 ? should I change the LPARAM accordingly?
NULL
|
|
|
|

No I guess not, is it working with VK_F1?
|
|
|
|

ok here is your explaination
1. Run your Application,
2. run spy++ and set it to capture KeyBorad messages (using Finder tool).
3. Press F1 key (or what ever key you want to send).
4. analyze the Messages log window and double click on the message having WM_KEYDOWN and nVirtualKey:VK_F1 or WM_KEYUP and nVirtualKey:VK_F1 . Get LPARAM value from there.
you are done.
The LPARAM valur for F1 remains constant. no matter where you run your application and when you run it.
This way u can get LPARAM values for all your virtual key simulations,
infact LPARAM contains bit combinations for ScanCode,RepeatCout,AltDown, Extended Value for the WM_KeyDown event.
Thanks
Azam
