The base class("PluginServ") implements the DllCanUnloadNow, DllGetClassObject, DllRegisterServer, and DllUnregisterServer.

So your definition of DllRegisterServer is PluginServ::DllRegisterServer, ie. it resides inside a class? These functions must be global, ie. not in a class, and they must be defined as __declspec(dllexport). Other than that, you'll have to give a bit more information.

Hi,

I need to implement code that detects a RegistryChangeEvent, but I haven't been able to figure out how to do this. Any ideas?

DO you want to know which changes were made in which key or just you want to know that something is changed?
The first is really difficult the second is easy... (I have the code for the second... I can post)

Well... I am a beginner ...

What I really need is to know that something has changed in a given key and that it is not an interim change.

Yes, please post your code.

Thanks,
Royce

Well you open the key you want normally and you use this code to intercept changes:

<br />
RegNotifyChangeKeyValue(yourHKEY, true ,REG_NOTIFY_CHANGE_ATTRIBUTES + REG_NOTIFY_CHANGE_LAST_SET + REG_NOTIFY_CHANGE_NAME + REG_NOTIFY_CHANGE_SECURITY , 0 ,false);<br />

It will not return until a change is made in the key so I recommand using this in a thread...
You can find more info about REG_NOTIFY_CHANGE... on MSDN...
I hope this helps...

Well... I am a beginner ...

WIN 32 programming questions. what do these libraries do?

I wonder what do the following libraries do?

odbc32.lib
odbccp32.lib
comctl32.lib
wsock32.lib

Those libraries were used in a open source project.
I downloaded the source code, and I'm now studying
them. Please tell me what do they do and used for
if you know.

Thanks.

odbc32.lib and odbccp32.lib are ODBC (Open Database Connection) libs. comctl32.lib is the Windows common controls lib, and wsock32.lib is the Windows sockets library. These are all import libs for the corresponding dlls.

Hi Ravi,

Thanks for your reply. However, I'm just started in
windows programming, would you give me more details
about those libraries?

What is Open Database Connections?
What is the difference between odbc32.lib and odbccp32.lib?
Do I have to include both of them to utilitize ODBC?

What is Windows sockets library? What is it used for?

Thanks

When you want to call any of the Windows multimedia APIs, for example to play WAV files, eject a CD, play an AVI loop, etc. See the Multimedia section at CP for more information.

DirectX pixel manipulator

vxje14-Aug-04 14:14

14-Aug-04 14:14

Hi,

I was just wondering if it's possible to build a pixel manipulator for directx so that the output image (the rendered scene) can be manipulated. Let's say I want to convert a normal scene as it would be rendered and shown on the screen to a black&white scene where pixels in the front are light and pixels in the back are darker.

Is this possible and where do I have to look for?

Thanks in advance,
Nicolas

This possibly isn't the best place for help on DirectX, www.gamedev.net [^]and www.flipcode.com[^] tend to have a larger audience of DirectX programmers who know the best answers to these types of questions.

Possibly all you need is a light source (point or spot) positioned in the correct position in your scene - it's hard to tell from your post.

If by 'pixel manipulator' you mean pixel shader I'm assuming that yes, it can be done - but it depends alot on your video card. I haven't done it myself, but I have seen some impressive results from cel-shading (essentially the opposite of what you're describing - it discards information to produce cartoonish output) but searching the nvidia or ati websites should dig up a few good resources on pixel-shading.

The other alternative is to render to texture, and then to apply some type of transformation directly to that texture. This approach works well for PC's without video cards with grunt, but beware it's resource hungry and reasonably slow.

If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.

Hi,

It's no possible, but you can use static members

class CMyClass
{
static CString m_sArr[4];
};

CString CMyClass::m_sArr[4] = {"a","b","c","d"};

How can I switch between "Code Comments" by keyboard!?

Visual C++ 6 editor help us to complete our Code by showing some useful data in Tooltip such as "Auto Type Info" or "Code Comments".

This option by default enabled in Tools->Option->Editor->"Statement Completion Option".

Some "Code Comments" has more than one comments.
e.g: "[1 of 3] void CMyClass::_MyOverloadedFunc(...);" will displayed in Tooltip.

We can switch between them by clicking on it by mouse.

So, How can I switch between "Code Comments" by keyboard!?

so can anybody give some hint how to do it , or article abut such news ticker.

even i dont mind to buy some news ticker component or stuff but i am not able to find one.
