Usually I do all what I can inside a class, in every method (try and catch). Am I doing it wrong? Recently I heard better way is handle error in program body...
What is good habit?
I'm looking for test vectors for AES-256 in CBC mode with essiv:sha256 for the IV-generation,

I was trying to get SDL to work on my mac but kept running into mysterious errors. After some googling, I realized that my issue was that SDL compiled in 32 bits, or was 32 bits, or something, and XCode was compiling my program in 64 bits. There were some solutions, as well, but all were very technical or required arcane knowledge which my novice brain did not comprehend. So, how can I either get a version of SDL that will work with a 64 bit compiler, or tell XCode to compile in 32 bits?
I have written a simple python module, it has this code:
_log = logging.getLogger("mymodule")
_started = False
def set_log_level(level):
_log.setLevel(level)
if not _started:
_hdlr = logging.FileHandler('mymodule.log')
When I call set_log_level() program fails because symbol _started is not found. It is normal because global _started is missing in the method. But my question is: symbol _log has the same visibility as _started, so why does this symbol can be found?

I need to implement searching for SD-cards in my program.
Currently I'm using search for all removable devices like:
searcher = New Management.ManagementObjectSearcher("\\localhost\root\cimv2", "SELECT DeviceId FROM Win32_LogicalDisk WHERE DriveType=2 AND Size>0");
But it find USB flash drives also. Is there a proper way to find SD-cards only?
What I need is in general only drive letter for available SD-cards (like "F:" or so).
I am a new iphone developer and was wondering if I could get some help with some code. I just want to know how to export basic character strings and variables to a website to be used by a third-party program.
Basically, if I had something as basic as:
int variableOne;
int variableTwo;
What code would I use to export these variables to a website?
I'm debugging a program with GDB.
unsigned int example = ~0;
gives me:
(gdb) x/4bt example
0xffd99788: 10101000 10010111 11011001 11111111
why is this not all 1's? i defined it as ~0... then the next line of code is:
example>>=(31);
and GDB gives me this when I try to examine the memory at bits:
(gdb) x/4bt example
0xffffffff: Cannot access memory at address 0xffffffff
what is going on???

I've been wondering if using long descriptive variable names in WinForms C# matters for performance? I'm asking this question since in AutoIt v3 (interpreted language) it was brought up that having variables with short names like aa instead of veryLongVariableName is much much faster (when program is bigger then 5 liner). I'm wondering if it's the same in C#?
Currently, I am testing every integer element against each other to find which ones match. The arrays do not contain duplicates within their own set. Also, the arrays are not always equal lengths. Are there any tricks to speed this up? I am doing this thousands of times, so it starting to become a bottle neck in my program, which is in C#.
I need to use C# to get data from database(sql) and the data in database is updated every few seconds. So do I have to make a loop or there is a better way to do that? Is it possible that when database is updating, the program can wait until it finishes updating? thx!

Hi all
When we install some applications in Winodws, we would get a dialog ask us if we want to attend the some consumer program, and send some system/applcation information to the company. Or when the Window server meets failure, it would also send error report to MS. I want to know, how can a application send information from client to report?

Besides Arduino, what other ways are there to learn hardware programming in a hands-on way? Are there any nifty kits available, either a pre-assembled robot, that you can program to move a certain way, or do certain things, or anything similar to that?

I am using Visual Studio to compile some C++ Code. When I compile my program in Debug mode it works perfectly, but when I try compiling it in Release mode, VS halts when Generating Code (ie: took 20 mins and still didn't finish). After I forced VS to stop the build process, the executable generated was huge 2MB while it should be about 304KB.
Please can you help figure this out. How should I setup the configuration parameters for Release mode to work?
Thanks,

I just got a bug report from someone running an app I wrote under Windows XP. He says it won't start up.
The application failed to initialize
properly (0xc0150002). Click on OK to
terminate the application.
It works fine at my end, (under Windows 7,) and I don't have any Win7- or Vista-specific stuff in the program, so it should work on XP too. How do I go about tracking this down and debugging it?
I am writing a program in Python, and want to get it to make the OS open the current working directory, making for instance Windows open explorer.exe and navigating to the wanted directory. Any ideas on how to do this?
The directory is already given by os.getcwd.
Cross platform methods preferred :)
I am getting confused with this plug in.
basically my target is to Deploy files from Server1 to Server2
now the buildoutput dir is in a specific location in Server1
example
E:\BuildOutput\Apps\Application1\Bin\
I need to deploy them in Server2
C:\Program Files\Tools\Application1\Bin\
How do I set up this plugin to work to what i need?
I am getting stressed in the amount of files that needs to be deployed to another server, i just wished a simple xcopy tool to another server could work.
I have written a java application which is a RMI server. I need to start rmiregistry to run this application and i also want my apllication to start automatically when the system starts.
I have converted my application into a windows servise. When i try to start my service it shows this error
Error 1067: The process terminated unexpectedly
Is it because my program throws an exception when my application is started before the rmiregistry is started.
