Hi,
I am writing a projet in C++ according to "CCSDS RECOMMENDEDATION FOR LOSSLESS DATA COMPRESSION" that is base on Rice coding algorithm. I am wondering if anybody has the source code that I can referce it.
Thanks a lot!

Hi, Ravi Bhavani,
Thank you for your information. I found this algorithm is different. What I am going to code is bassed on the NASA's Lossless Data Compression recommendation that modified the original Rice
code algorithm and seperated the algorithm into two parts: preprocessor and Adaptive Entropy Coder( http://www.ccsds.org//ccsds/). I searched throught the internet and found the corresponding source code named "SZIP", but I can not get any idea from there. I am wondering if you have heared
anything about this special Rice coding?

I placed a 'Reset' button on my property sheet right by the 'OK', 'Cancel', and 'Apply' buttons. I was wondering if anybody knew if there was a standard ID number for a 'Reset' button?
OK - IDOK - 1
Cancel - IDCANCEL - 2
Apply - ID_APPLY_NOW - 12321
Reset - ID_RESET??? - ???
I have currently defined a value of ID_RESET to 10055.

I don't think so. The only "standard" ids I found in winuser.h were:
#define IDOK 1
#define IDCANCEL 2
#define IDABORT 3
#define IDRETRY 4
#define IDIGNORE 5
#define IDYES 6
#define IDNO 7
#if(WINVER >= 0x0400)
#define IDCLOSE 8
#define IDHELP 9
#endif /* WINVER >= 0x0400 */ /ravi

Thanks Ravi.
I also found those IDs. It is just that ID_APPLY_NOW is not in that list. It is in AfxRes.h along with the other property sheet buttons. So I was just wondering if the reset button was defined some where. I prefer to use standard IDs if there are any.
I will will leave it as it is.

Hello there
As a beginner in windows application programming I've run into a few problems - the most annoying being at a message posting procedure where the message never receives the intended recipient.
I've got a DLL which is intended for posting messages to an dialog at certain events. This posting are carried out by PostMessage. But the problem is that the message never arrives at the dialog. I've used Spy++ to check the handle of the intended recipient and the handle stored in the DLL, and they match. The return code of the PostMessage, is 0 = successful posting, but the dialog never receives the message (I've checked this with Spy++).
If I use HWND_BROADCAST as the first argument for PostMessage, my dialog receives the message correctly, thus i assume that my event handler in the dialog is correct.
What can be wrong?
Best regards
Thomas René Sidor

If the function fails, the return value is zero. To get extended error information, call GetLastError.

I have used GetLastError, and the function itself does not fail. The problem is just that the message never arrives at the intended window.
Best regards

PostMessage's return type is BOOL. 0 means FALSE, which means that the message was NOT posted. Again, use GetLastError to work out why.

The method does not return 0. Therefore the use of GetLastError just tells that the command was succesfull.

This is from your original post:
The return code of the PostMessage, is 0 = successful posting...
So what is the return value of PostMessage()?

Damn, maybe I could be a little more clear on what I'm trying to say 
My PostMessage does not return 0, that means that it does not fail. By using GetLastError() - i get Error code 0: Succesful...
Sorry for the mixup

I'm creating a console mode based project where there will be a neat looking menu system! What I'd love to know is, can I place the input focus from one part of the screen to another... e.g.
|--Menu---||-----Please input value----------|
|-Option 1-||--Input value:-------------------|
|-Option 2-||--You inputted..----------------|
|-Option 3-||--------------------------------|
|---focus--||--focus-------------------------|
|----------||--------------------------------|
As you can see - I'd like to be able to transfer focus from the menu to the input box (box shapes are created with ASCII characters and a heck of a lot of careful spacing! lol) whenever the user wants to by the press of a button.
Is this possible, and if so can someone please tell me! I'm using Microsoft Visual C++ Standard Edition. Any help would be well appreciated!!!

How can i write a program and get it to start during the Windows boot process? Kind of like chkdsk.exe when you haven't shut your computer down properly, it gets displayed during bootup but XP hasn't fully loaded yet.

The utility is called Autochk.exe. It is a "native application". This category lies somewhere between a device driver and a user mode app.
At boot time, the user mode-style apps cannot run since major window's components used for usermode(user.exe,gdi etc.) are not loaded.
in these cases, a native app is the only choice available. you need the xp/2000 ddk to make this kind of apps.
Notice that when you running autochk.exe after XP/NT has started, you get an error message "The autochk application cannot be run in Win32 mode".
To start such an app at boot time, see the registry key
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager and the value stirng value "BootExecute".
Usually, this value is "autocheck autochk *", but you can change that...

I want to display a large image, so I don't use CScrollView, instead I use CView and add the scroll bar manually with the coolsb library, On the horizontal and vertical scroll bar cross point, that is the bottom-right corner, I want to create a button as a navigation button,just like Gimp(a software like photoshop on Linux) I create it from the child frame class, add some code on the OnCreate()and OnSize(), but the Rect size is difficult to compute, I don't know why. so I need some help.

Hi,
You must adds follow lines in some init function. For example in InitInstance of the your app:
AfxSocketInit();
AfxOleInit();

I'm trying to retrieve the Datbase Name, Server Name, and, if Oracle, the Net 8 Name set in an ODBC DSN without first opening the ODBC Connection. The idea is for the user to specify an ODBC DSN and the application will get the information about the DSN to open an ADO Connection. The only way that I've found to retrieve this information is to first open the connection using ODBC. This seems like an very inefficient way to get the information. I know that i can retrieve if from the registry, but that way has already been shot down by my supervisor. Preferabley I need to get it from some kind of Win32 API call. Anybody have any idea how to do this?

Is it possible to hide or to disable the access to the hard drive by using the registry? If not: Could somebody give me a source code (Win32 APP).

I renumbered via a utility (see http://www.annasplace.me.uk/resorg/)my resouces. This was due to the Icon not being displayed, the help Memu not being displayed and a check box not operating correctly.
I now get the Assertion at
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);<br />
ASSERT(IDM_ABOUTBOX < 0xF000);
in my OnInitDialog routine.
The current value of IDM_ABOUTBOX = 0x10
Are they any way for the resources to be checked
A snipit of the resource.h file is as follows:
#define IDM_ABOUTBOX 0x10<br />
#define IDR_MANIFEST 11<br />
#define IDD_SSIC_EXAMPLE_DIALOG 12<br />
#define IDR_HTML_GENERICRTSIM 13<br />
#define IDR_MAINFRAME 14<br />
#define IDM_MAINFRAME 19<br />

#define ID__LOADPROJECT 32777<br />
...<br />
#define ID_FILE_EXIT 32787<br />
#define ID_HELP_ABOUT 32788<br />

#define _APS_NEXT_CONTROL_VALUE 1452<br />

#endif
I assume that they are bugs with the IDE, any suggestion please.

Your question is not exactly clear. What is the problem? The ASSERT? Well, change the value of IDM_ABOUTBOX then! What are the bugs you suspect in the IDE? The resource.h look ok to me.
