There is an error enumeration that already exists in the C++ app that I need to use in the C# app.
I don't want to just redeclare the enumeration in C# because that could cause sync issues down the line if the files aren't updated together.

Is there a way for me to taken an enumeration declared like so:
typedef enum

The app actually consists of 2 parts, one runs on Windows and interacts with a user and another is a linux part that runs from a LiveCD. User makes a choice of Windows drive letters and then a linux part performs actions with corresponding partitions. The problem is finding a match between a Windows drive letter (like C:) and a linux device name (like /dev/sda1). This is my current solution that I rate as ugly:
- store partitions information (i.e. drive letter, number of blocks, drive serial number etc.) in Windows in some pre-defined place (i.e. the root of the system partition).
- read a list of partitions from /proc/partitions. Get only those partitions that has major number for SCSI or IDE hard drives and minor number that identifies them as real partitions and not the whole disks.
- Try to mount each of them with either ntfs or vfat file systems. Check whether the mounted partition contains the information stored by Windows app.
- Upon finding the required information written by the Windows app make the actual match. For each partition found in /proc/partitions acquire drive serial number (via HDIO_GET_IDENTITY syscall), number of blocks (from /proc/partitions) and drive offset (/sys/blocks/drive_path/partition_name/start), compare this to the Windows information and if this matches - store a Windows drive letter along with a linux device name.
There are a couple of problems in this scheme:
- This is ugly. Writing data in Windows and then reading it in Linux makes testing a nightmare.
- linux device major number is compared only with IDE or SCSI devices. This would probably fail, i.e. on USB or FireWire disks. It's possible to add these types of disks, but limiting the app to only known subset of possible devices seems to be rather bad idea.
- looks like HDIO_GET_IDENTITY works only on IDE and SATA drives.
- /sys/block hack may not work on other than IDE or SATA drives.
Any ideas on how to improve this schema? Perhaps there is another way to determine windows names without writing all the data in windows app?

===
What are your opinions on developing for the command line first, then adding a GUI on after the fact by simply calling the command line methods?
eg.
W:\ todo AddTask "meeting with John, re: login peer review" "John's office" "2008-08-22" "14:00"
loads todo.exe and calls a function called AddTask that does some validation and throws the meeting in a database.
Eventually you add in a screen for this:
============================================================
Event: [meeting with John, re: login peer review]
Location: [John's office]
Date: [Fri. Aug. 22, 2008]
Time: [ 2:00 PM]
[Clear] [Submit]
============================================================
When you click submit, it calls the same AddTask function.
Is this considered:

Currently: I have three arrays of regex, one for valid filenames, one for files missing an episode name, and one for valid paths.
Then, I loop though each valid-filename regex, if it matches, append it to a "valid" dict, if not, do the same with the missing-ep-name regexs, if it matches this I append it to an "invalid" dict with an error code (2:'missing epsiode name'), if it matches neither, it gets added to invalid with the 'malformed name' error code.
The current code can be found [here](http://github.com/dbr/checktveps/tree/8a6dc68ad61e684c8d8f0ca1dc37a22d1c51aa82/2checkTvEps.py)
I want to add a rule that checks for the presence of a folder.jpg file in each directory, but to add this would make the code substantially more messy in it's current state..
How could I write this system in a more expandable way?
The rules it needs to check would be..
- File is in the format `Show Name - [01x23] - Episode Name.avi` or `Show Name - [01xSpecial02] - Special Name.avi` or `Show Name - [01xExtra01] - Extra Name.avi`
- If filename is in the format `Show Name - [01x23].avi` display it a 'missing episode name' section of the output
- The path should be in the format `Show Name/season 2/the_file.avi` (where season 2 should be the correct season number in the filename)
- each `Show Name/season 1/` folder should contain "folder.jpg"
.any ideas? While I'm trying to check TV episodes, this concept/code should be able to apply to many things..
The only thought I had was a list of dicts in the format:
checker = [
{
'name':'valid files',
'type':'file',
'function':check_valid(), # runs check_valid() on all files
'status':0 # if it returns True, this is the status the file gets

I need to write a stored procedure that returns how many jobs each person has at each stage.
So far I have this (simplified):
DECLARE @ResultTable table
(
StaffName nvarchar(100),
Stage1Count int,
Stage2Count int
)
INSERT INTO @ResultTable (StaffName, Stage1Count)
SELECT StaffName, COUNT(*) FROM ViewJob
WHERE InStage1 = 1
GROUP BY StaffName
INSERT INTO @ResultTable (StaffName, Stage2Count)
SELECT StaffName, COUNT(*) FROM ViewJob
WHERE InStage2 = 1
GROUP BY StaffName
The problem with that is that the rows don't combine. So if a staff member has jobs in stage1 and stage2 there's two rows in @ResultTable. What I would really like to do is to update the row if one exists for the staff member and insert a new row if one doesn't exist.
Does anyone know how to do this, or can suggest a different approach?
I would really like to avoid using cursors to iterate on the list of users (but that's my fall back option).

Something that constantly frustrates me is that people don't want to learn any more than they need to about the programming languages they use every day.
Many programmers seem content to learn some pidgin sub-dialect, and stick with that. If they see a keyword or construct that they aren't familiar with, they'll complain that the code is "tricky."
What would you think of a civil engineer who shied away from calculus because it had "all those tricky math symbols?"
I'm not suggesting that we all need to become "language lawyers." But if you make your living as a programmer, and claim to be a competent user of language X, then I think at a minimum you should know the following:
- What are all the keywords of the language?
- What are all the valid syntactic forms?
- How are memory, files, and other operating system resources managed?
- Where is the official language specification and library reference for the language?
The last one is the one that really gets me. Many programmers seem to have no idea that there is a "specification" or "standard" for any particular language. I still talk to people who think that Microsoft invented C++, and that if a program doesn't compile under VC6, it's not a valid C++ program.
Programmers these days have it easy when it comes to obtaining specs. Newer languages like C#, Java, Python, Ruby, etc. all have their documentation available for free from the vendors' web sites. Older languages and platforms often have standards controlled by standards bodies that demand payment for specs, but even that shouldn't be a deterrent: the C++ standard is available from ISO for $30 (and why am I the only person I know who has a copy?).
Programming is hard enough even when you do know the language. If you don't, I don't see how you have a chance.
What do the rest of you think? Am I right, or should we all be content with the typical level of programming language expertise? | language-features | language-agnostic | rant | null | null | null | open | Do You Really Know Your Programming Languages?
===
I am often amazed at how little some of my colleagues know or care about their craft. Something that constantly frustrates me is that people don't want to learn any more than they need to about the programming languages they use every day.
Many programmers seem content to learn some pidgin sub-dialect, and stick with that. If they see a keyword or construct that they aren't familiar with, they'll complain that the code is "tricky."
What would you think of a civil engineer who shied away from calculus because it had "all those tricky math symbols?"
I'm not suggesting that we all need to become "language lawyers." But if you make your living as a programmer, and claim to be a competent user of language X, then I think at a minimum you should know the following:
- What are all the keywords of the language?
- What are all the valid syntactic forms?
- How are memory, files, and other operating system resources managed?
- Where is the official language specification and library reference for the language?
The last one is the one that really gets me. Many programmers seem to have no idea that there is a "specification" or "standard" for any particular language. I still talk to people who think that Microsoft invented C++, and that if a program doesn't compile under VC6, it's not a valid C++ program.

<request xmlns="http://internalservice.net/messageprocessing">
<task>....various xml</task>

When I capture packets on the wire I can see that the inbound XML to the web service is unmolested so it's the .NET WS stack that's adding this namespace. If I call the web service from a .NET client (Add web reference etc) then the default namespace is empty, as it should be.
It's been so long since I used the ASP/SOAP toolkit to call into .NET webservices, I can't remember all the clever tricks I used to pull to get around stuff like this.
Any ideas? One solution is to knock up a COM callable .NET proxy that takes the XML as a string param and calls the WS on my behalf, but it's an extra layer of complexity/work I hoped not to do.
Thanks for looking.

However, to serialize to XML, I am simply decorating the class and its members with the _Xml???_ attributes ( _XmlRoot_ , _XmlElement_ etc.) and then passing it to the _XmlSerializer_ and a _StringWriter_ to get the string. Which is all good. I intend to put the method to return the string into a generic utility method so I dont need to worry about type etc.

Personally, I think it is A BAD THING.
My reasons are thrice:
1) It circumvents my well architectured MVP framework - with databinding, the view communicates bi-directionally with a model. Ewww.
2) It promotes hooking up view controls to datafields at design time. In my experience, this leads to vital code (binding column A to Field X) being obscure and hidden away in some designer file. IMO this code should be explicit and in-your-face, so that it is easy to modify and see what is going on, without having to use a clunky designer interface.
3) Relating to Point 1) this direct binding makes it harder to isolate each component (view, model, controller/presenter) and unit-test.
The PROS are that it is easy to set up, and you can take advantage of some nice features (validation etc) which come with the plumbing already done for you.
But for me, databinding becomes much more of a hindrance when dealing with a large data-centric application.
Any thoughts?

There are usually plenty of books and tutorials on the subject but you aren't sure there most of them are of any good.
So, how should you plan your learning process in order to get on the right track or to realize that isn't the right thing for you without wasting much time? Or how to grasp the essential concepts of a new technology?
I'm pretty sure there are lot of people who would change the way they learned their first programming language.
There are some questions which look like this one ([1][1],[2][2],[3][3]), but I think I'm trying to ask more general question here.

===
I wonder is there a good strategy to use when you're about to start learning completely new stuff.
For example, you want to learn LISP and you know nothing about functional programming and you've been always working with imperative languages, or you want to learn Aspect-Oriented programming and have no clue what's all about.
There are usually plenty of books and tutorials on the subject but you aren't sure there most of them are of any good.
So, how should you plan your learning process in order to get on the right track or to realize that isn't the right thing for you without wasting much time? Or how to grasp the essential concepts of a new technology?

Status MyFunction()
{
if(...) // something bad
return new Status(false, "Something went wrong")
else
return new Status(true, "OK");
}
You get the idea.
All callers of MyFunction *should* check the returned Status:
Status myStatus = MyFunction();
if ( ! myStatus.IsOK() )
// handle it, show a message,...
Lazy callers however can ignore the Status.
MyFunction(); // call function and ignore returned Status
or
{
Status myStatus = MyFunction();
} // loose all references to myStatus, without calling IsOK() on it
Is it possible to make this impossible? e.g. an throw exception
**In general**: is it possible to write a C# class on which you *have* to call a certain function?
In the C++ version of the Status class, I can write a test on some private bool bIsChecked in the *destructor* and ring some bells when someone doesn't check this instance.
What is the equivalent option in C#?
I read somewhere that "You don't want a destructor in your C# class"
Is the Dispose method of the IDisposable interface an option?
In this case there are no unmanaged resources to free.
Additionally, it is not determined *when* the GC will dispose the object.
When it eventually gets disposed, is it still possible to know where and when you ignored that specific Status instance?
The "using" keyword does help, but again, it is not *required* for lazy callers.
Thanks in advance!

Works perfectly.
The configuration section is present in the App.config but for some reason ConfigurationManager refuses to load the system.ServiceModel section.

Developers are spread around the world, so you can't always meet up and time differences mean that phone/VOIP is not always practical.
I find email hard to manage. You end up with hundreds/thousands of emails in various threads. You get CC'ed on stuff that is of marginal interest to you. Some emails have a useful lifespan on minutes or hours, but you still have to manually delete them.
I'm stuck with Outlook, but gain some benefit from:
1. Arrange by Conversation. So I can easily see if someone has already replied. I often just delete the earlier messages if I can assume that their content will be duplicated in the later ones. One problem is that my own replies will be in my Sent Items
2. Google Desktop Search. Infinitely quicker than Outlook's
So what are the alternatives for office communication?
1. IM - Great for ephemeral info and you can tell if the recipient is around. But not generally archived.
2. Twitter/Identi.ca microblogging - Could be used to track history of group communications if you can work around confidentiality and message length
3. Wiki - I like wikis, but getting people to use them can be hard and no good for instant response. A better place for reference information than directly in emails
Something like Gmail/Gtalk with its searchable archive would be an improvement on what we have, but I don't know how this could integrate with 'standards' like Outlook.
