You will needed to create a DIB section and routines to read and write the pixels directly. The book "Programming Windows" contains code for doing this (no trig. required). Alternatly, on windows 2000 and above you can use world transforms (a bit tricky).

1) How to set the sound channel volumes and (un)mute those channels using the Windows API?
2) I saw SpyXX.exe Loading a library remotely (loading spyhook55.dll under winamp.exe, for instance). How can I do that?

Hi folks!
I want to program a tool that only stays as a tray-icon.
My problem is how to design it in MFC.
The application is a CWinApp, but without a Window in m_pMainWnd it closes immediately.
How do I build an application that runs without a window?
Do I need a valid hwnd for Shell_NotifyIcon()? (I tryed with NULL as hwnd and it seemed to work..)
One solution may be to create a window but never show it. But perhaps there is a better way out there... 
Thanks!

You could actually search this site...
One of the very first articles here was a Tray icon application by Chris Maunder.
Just search for tray icon etc.

I am writting a C/S program based by Socket and IO completion.
I use CreateIoCompletionPort and GetQueuedCompletionStatus to build and get the connected socket. The Server program goes well when it is built.
I also built a client for testing server.But a problem comes.
If I use one client to connect the server, everything is fine.
IF I use two more client to connect the server at the same time, the server handle them one by one.It doesn't handle them synchronously as I expected.
Does anyone know the reason. Anyone is so kind to replay me?
Thanks.

Really?
Sorry, i have tried a lot. But it isn't improved.
I am locked by the it.
Can u tell the detail of the key ?

hmm, unless you have 2+ CPU box, it will handle them always synchronously. IOCP only can help somehow masquerade it.
Checklist for the very beginning
- are your sockets initialized as OVERLAPPED?
- are there more threads waiting in GetQueuetCompletionStatus?
- what about the return codes from WSASend/FileWrite, are they correct?
- is the problem while accepting the clients, or while communicating?

My xml file is below:
<?xml version="1.0" encoding="GB2312"?>
<root>
<node1>
<bmname>sichuan.bmp</bmname>
</node1>
<list>
<city>
<cityname>ganzi</cityname>
<point>(190,270)</point>
</city>
<city>
<cityname>mianyang</cityname>
<point>(467,190)</point>
</city>
<city>
<cityname>yaan</cityname>
<point>(346,335)</point>
</city>
</list>
</root>
There will be many cities in xml file,and I want to get city name,point of a city at a time and store them into a struct,then I use selectNodes("list"),but it return a NULL pointer, thus I consider that the only list node is the reason,so I use selectSingleNode("list"),but it also cannot work and return NULL pointer,I've no idea,hope your help

hi,
use XPath query language.
"//list/city/*"
pass this query to SelectNodes(); it will return u list of cities.
Try it out. I cannot give u compilable code as I am using .NET IDE now a days.
Search on MSDN @ writting XPath query.

I have tried it, but it's the same, I have to ask for your help.When I use XPath:"//list/city/*", it returns a zero length, when I use "//city/*", it returns all of the nodes in list node rather than the number of citis, but I have to get the number of cities.
I love Aquamarine.

hi,
try to understand syntax of XPath. its simple.
first "/" means root node, second "/" means child node, in ur case "list" level, now u need to fire query to enumerate cities.
when u say "//city/*" u r on level of "city" node and u r gathering infor inside city node.
try this
"/list/city/*"
Try this out, till the time I will explore how 2 use XML in .NET!!

Solve it with XPath:"//citylist[1]/*", thank you for your reply.

 In the project of cximage! How to debug ? In details ,I want to know when and how the program run in the j2k's code ? who can tell me? I thank you him/her first!!!
|
|
|
|
|
You should ask this question directly to the author, but as far as i know, you should compile the cximage in debug version, put the breakpoint where you need them and then debug the appilcation, surely you will get to the point where you want to debug..

Prakash.
