Note that minimum supported clients for this function are Windows Vista and Windows XP with SP1. If you want to support older windows versions you can use NtQuerySystemInformation[^]. Look for SYSTEM_PROCESS_INFORMATION class and read the documentation carefully before using this function. I hope this helps. Re: how to get all handles of process so0_lanhlung216-Mar-11 5:09 so0_lanhlung2 16-Mar-11 5:09  thanks. i 'll research...do you have a help document for me? Re: how to get all handles of process Nuri Ismail16-Mar-11 7:00 Nuri Ismail 16-Mar-11 7:00  Well I already gave you the link to the documentations of two APIs. The usage of GetProcessHandleCount is trivial, documentation says everything you need. For NtQuerySystemInformation you can check out this[^] thread, where you will find a sample code that actually retrieves Handle Count, Thread Count, etc. The example code actually uses ZwQuerySystemInformation[^] function but in fact this does not change anything for you, the usage is exactly the same. P.S. If you actually want to know the difference between 'Nt' and "Zw' prefixed native API functions, have a look at this interesting article[^]. How to write a safe RPC program?

But i wrote 9 or 11 or any other number than 10 ,it increase offset by 1 means offset increase from 152 to 153. it works fine on Linux but giving issue on windows. Regards, Sachin Re: Issue to write a value 10 using fwrite «_Superman_»15-Mar-11 20:20 «_Superman_» 15-Mar-11 20:20  The value 10 in binary means a new line character. In Windows, a new line is converted to a new line / carriage return character pair. Linux and Unix do not do this. Thats the reason for this behavior. «_Superman_»  I love work.

If in windows writing 10 to file treat as different operation as mentioned above, Can you please suggest me alternate way to write value 10 in file i.e. in which format I should pass parameter to fwrite() Regards, Sachin Re: Issue to write a value 10 using fwrite cancerion15-Mar-11 21:10 cancerion 15-Mar-11 21:10  Thanks once again Santosh.

How to Capture Screenshot of a Full Screen Game Made with Direct X SoftwareDeveloperGoa15-Mar-11 8:36 SoftwareDeveloperGoa 15-Mar-11 8:36  Hello Friends Is there a way in which we can capture screenshot of a game built in direct x. I registered a shortcut key using RegisterHotKey to display a test messagebox, launched Star Wars and pressed the shortcut key configured. No messagebox appeared and hence it seems that the system wide shortcut keys of keyboard registered using RegisterHotKey do not work. Or it means that Direct X creates it's own secure environment in which no other software made in directx or win32 or c++ can internein ? Regards Writing vKVM/VNC/Remote Desktop Server using C in LINUX Andy Rama15-Mar-11 4:55 Andy Rama 15-Mar-11 4:55  Hi All, I am working on my college project "Virtual Keyboard Video Mouse (vKVM) Server using C on LINUX". (Probably Server will have Graphics Data available in provided memory location) I searched on Internet. It's similar to to "Virtual Networking Computing (VNC)" & "Remote Desktop". VNC uses Remote Frame Buffering (RFB) Protocol for it. I studied "LibVNCServer" but couldn't use it. Please suggest me how to approach for this project? How should I start writing code for it? Initial requirement of project is Basic Server to transmit video/desktop data is also fine. Please help me for that. Thanks & Regards, Aniket A.

In that case you are going to have to write your own versions of the client and the server modules. I suspect that this is not a trivial task and an understanding of the existing libraries is a prerequisite. If you mean that you cannot understand these libraries then you probably need to reconsider the task you have set yourself. I must get a clever new signature for 2011. Re: Writing vKVM/VNC/Remote Desktop Server using C in LINUX CPallini15-Mar-11 9:12 CPallini 15-Mar-11 9:12  Well, for a college project it's probably easier going on without studying VNC protocols and libraries. I would study TCP/IP, design a basic, very simple, protocol and implement my own client and server (they won't be light-fast, but I suppose that's not required). If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

I've seen other articles floating around with implementations of remote control software, try looking around for those...

Dirk van Boxel14-Mar-11 23:26 Dirk van Boxel 14-Mar-11 23:26  I am using Visual Studio 5 C++. The platform is Windows CE 6.0 R3. I need to load a bitmap from file and need the HBITMAP handle to use in my program. I have searched the Internet for this with no result. SHLoadImagefile() I can't use. OleLoadPicture() I may can use but gives me a unresolved external. Maybe someone has encountered this problem before and want to share the solution with me. Re: how to load a bitmap from file?

Dirk van Boxel15-Mar-11 0:32 Dirk van Boxel 15-Mar-11 0:32  LoadImage() is suppoted for Windows CE but dous not support load from file (LR_LOADFROMFILE) I am afreid. Thanks for your answer. Re: how to load a bitmap from file? Code-o-mat15-Mar-11 1:28 Code-o-mat 15-Mar-11 1:28  Does SHLoadDIBitmap[^] work maybe? [MSDN RANT]Is it me or does MSDN confuse the hell out of one? If you check it here[^] it says: lpszName ... If the fuLoad parameter includes the LR_LOADFROMFILE value, lpszName is the name of the file that contains the image. fuLoad [in] Set to zero. ... So basicly this says: if you use LR_LOADFROMFILE then you can load a bitmap from file, but wait, you can't because you have to specify 0 for fuLoad. Gee, thanks.

Dirk van Boxel15-Mar-11 2:30 Dirk van Boxel 15-Mar-11 2:30  Does SHLoadDIBitmap[^] work maybe? No it does not work, but it compiled OK and the handle it returnes looks OK. The LR_LOADFROMFILE is not supported for win CE and yes that MSDN article is confusing. Thanks for your time.
