I've got some experience with Bash, which I don't mind, but now that I'm doing a lot of Windows development I'm needing to do basic stuff/write basic scripts using
the Windows command-line language. For some reason said language really irritates me, so I was considering learning Python and using that instead.
Is Python suitable for such things? Moving files around, creating scripts to do things like unzipping a backup and restoring a SQL database, etc.
Hi. I'm trying to pivot some data in SQL Server 2000, but the user that runs the application only have read/write permissions. I've looked the solutions posted here, but all involving create/destroy temporary tables.
I have to write a drop down query for countries.
But USA should always be first.
The rest of the countries are in alphabetical order
I tried the following query
SELECT
countries_id
,countries_name
FROM get_countries
WHERE
countries_id = 138
UNION
SELECT
countries_id
,countries_name
FROM get_countries
WHERE
countries_id != 138
ORDER BY 2 ASC
Basically I have a navbar and a title, that both have the properties,
position: fixed;
top: (VALUE I INSERTED);
My problem is that obviously when I write the main body of the document the text is underneath the title/navbar. I need to get the text to be underneath the title and navbar, but without it having a fixed position. If any more information with code is needed, just comment saying so.
Thanks in advance.
Similar to this question. I would like to find all commented files. But in my case /* */ is a possibility.
Apparently when you write changes to a database project, dropped objects are only commented out instead of deleting the file. I would like to remove all of these commented out files from the project.
Is is possible to find all files which start with /* and end with */?
Is there a simple way to invert a WPF GridView so that items are bound to columns instead of rows? Or would it be necessary to write a custom view mode?
Hi,
I've had to write an application that lists and plays tutorial videos along with accompanying text. It works well but since the videos are added by the user I need a way of checking to see whether or not a video can be played on the machine.
I'm not sure whether or not there is an easy way to try test the file (and catch errors) or if I need to start looking at codecs installed.
Does anybody have any experience with this?
I need to track the completion of tasks for users.
I started by having a row called "first_login", "profile_complete", "other_thing_complete", etc...
I'd like to combine these all into one row "activity_state".
I just don't know how to properly store data in this field, and how to retrieve it.
What kind of field should it be, and how should I read/write to it?
I have a problem with "pairing" arrays into one (by index). Here is an example:
INPUT:
inputArray = [ [0, 1, 2, 3, 4], [2, 3, 5, 7, 8], [9, 6, 1] ]
OUTPUT:
outputArray = [
[0,2,9],
[1,3,6],
[2,5,1],
[3,7,chooseRandom()],
[4,8,chooseRandom()]]
Questions:
1) How to avoid out of range problem
2) How to write chooseRandom() to choose N neighbour
I'm using python but feel free to share your thoughts in any language.
Hi, I would like to write the following code in c#.
a) small console application that simulates memory leak.
b) small console application that would invoke the above application and release it right away simulating managing memory leak problem..
In other words the (b) application would continuously call and release application (a) to simulate how the "rebellious" memory leak application is being contained with out addressing the root cause which is application (a).
Some sample code for application (a) and (b) would be very helpful.
Thanks

Say I have multiple EditTexts in an application. When I click a Button, I want to test what EditTexts are empty and what EditTexts have content. How would I do that? Could someone write the code for the Button click handler.
Is there anything like Beanshell, which exposes CLR classes instead of Java classes, and lets you write scripts in C# or VB.Net (or any .Net language for that matter)
Should come in handy to test one-liner code snippets
Write a recursive method that converts a decimal number into a binary number as a string. The method header is as follows:
public static String convertDecimalToBinary(int value)
I find myself doing this a lot:
script/generate migration my_new_migration
.. then select & copy the generated filename, then paste it into vi to actually write the migration.
Is there any way to do this in one step? i.e. when the script/generate migration runs, it creates the file the automatically opens that file in an editor?

I have the following questions concerning the differences between the four options:
What is the main difference between the four options?
Which of the above support int64_t or long long without suffix LL. I want a data type of the range 2^63 - 1
If your answer to my second question is not C(gcc 4.3.2) , whether the code I write in C(gcc 4.3.2) for C language will be valid in rest of the three options or do I have to modify something, then what will be those modifications.
I often find this strange CDATA tag in XML files:
<![CDATA[]]>
I have observed that this CDATA tag always comes at the beginning, and then followed by some stuff.
But sometimes it is used, sometimes it is not. I assume it is to mark that some "data" will be inserted after that. But what kind of "data"? Isn't anything I write in XML tags some sort of "data"?
I need to parse a simple DSL which looks like this:
funcA Type1 a (funcB Type1 b) ReturnType c
As I have no experience with grammer parsing tools, I thought it would be quicker to write a basic parser myself (in Java).
Would it be better, even for a simple DSL, for me to use something like ANTLR and construct a proper grammer definition?
I am trying to write a simple Perl CGI script that:
runs a CLI script
reads the resulting .out file and converts the data in the file to an HTML table.

Suppose I have my models set up already.
class books(models.Model):
title = models.CharField...
ISBN = models.Integer...
What if I want to add this column to my table?
user = models.ForeignKey(User, unique=True)
How would I write the raw SQL in my database so that this column works?
The first one below works, but, just wanted to see if there's a better way...
If I'm trying to find all records that start with 'C' with either a flag of 2 or a status of 9, do I need to incorporate the 'C' criteria twice?
i.e.,
"SELECT * FROM mytable WHERE name like 'C%' AND flag = 2 OR name like 'C%' AND status = 9"
Or, is there a way quicker way to write it so that I only need to set 'C%' once?
