I think the problem comes from the way bytes are ordered in memory.
When you treat a 4-byte block as a DWORD, the bytes are not in order from MSB to LSB. It depends upon your hardware.
You can verify this in the debugger. Place a breakpoint anywhere you are using the DWORD variable, and then when it breaks, switch to Disassembly view. (Make sure "Show code bytes" is on.) You'll see the way the bytes are ordered, and it's not what you expect!
The difficult we do right away...
...the impossible takes slightly longer.
In this case we have to implement an algorithm for packing 4 bytes to a single dword programmatically.
Also, there's no default conversion. DWORD data type is 32 bits = 4 bytes long regardless of it's x64 or x86 mode.
Hercules has a function FETCH_FW which will take a MainFrame fullword 4 bytes and put in the right sequence for Windows/Linux However it is still coming in EBCDIC and I need to convert it to ASCII thus I need to access every byte and convert it the function FETCH_FW takes as 1st param a DWORD I thought using unsigned char would produce the same result apparently not
I'm currently doing my Masters in Computer Network Engg and I have decided to do my Final semester project in optimisation of firewalls.
I'm thinking of implementing firewall optimisation using rule re-ordering and rule conflict detection, but I don't have a clue on how to get started.
I got to know that I can make use of Windows Firewall API (NetFwTypeLib) and work on top of Windows Firewall but I'm not quite sure if this would help me or not.
If you have done anything similar or have some pointers for me please guide me.
I have a database creation script. I've run the script after changed the path within the 'FILENAME' option to create the database on an external hard disk and I was able to see and select data from tables as the script run with no errors. However, when I tried to connect to the database from an application and read data from database tables, an exception thrown for SQL Server error 823 "The operating system returned error 21(The device is not ready.) to SQL Server during a read at offset 0x00000000132000 in file 'Database name'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.". I've tried to run database consistency commands against it but they did not carried out and I got an error message. Also when I tried to drop or recover the database, dropping and recovering process failed. Finally, I had to make the database offline then I dropped it. I need to create such database on my external hard disk not on my primary one. Can anyone help?!!!
My English is very pool,pardon me.This is my first time here.Today I come here to introduce a C++ program library which written by myself.This library called Covariant Graphics Library.This library can run on Linux,based on C++14 standard.If you have some questions about me and my library,just tell me.
This program doesn't compile and gives me error "Conficting types of L search" . I ran out of all trials and I am so confused why the heck it gives me this error . I would appreciate your contributions to solve my problem .
the function does front back search of an array, if any number matches it sends back its address.
