  • Dealing w/ Sqlite Join results in a cursor

    - by Bill
    I have a one-many relationship in my local Sqlite db. Pretty basic stuff. When I do my left outer join I get back results that look like this: the resulting cursor has multiple rows that look like this: A1.id | A1.column1 | A1.column2 | B1.a_id_fk | B1.column1 | B1.column2 A1.id | A1.column1 | A1.column2 | B2.a_id_fk | B2.column1 | B2.column2 and so on... Is there a standard practice or method of dealing with results like this ? Clearly there is only A1, but it has many B-n relationships. I am coming close to using multiple queries instead of the "relational db way". Hopefully I am just not aware of the better way to do things. I intend to expose this query via a content provider and I would hate for all of the consumers to have to write the same aggregation logic.

  • SharePoint 2010 is forcing me to safe PDF when opening from doc library

    - by Tobias Funke
    I have a document library with a PDF file. Whenever I click on the PDF file, I am prompted to save the file. I do not get the option of opening the file, I am forced to save it. What I want is for the PDF file to open, either in the browser or in a separate Adobe Reader window, depending on the Adobe Reader settings. I'm pretty sure SharePoint is responsible for this behavior, because if I put the PDF on my hard drive, then create a HTML file with a link to the file, it opens in the browser when I click on it. Please note: I looked at this question and did not help. I don't care if the PDF opens in the browser or in a separate Adobe Reader window, I just want it to open.

  • Do you leave historical code commented out in classes that you update?

    - by 18Rabbit
    When you need to obsolete a section of code (say either the business rules changed, or the old system has been reworked to use a new framework or something) do you delete it from the file or do you comment it out and then put in the new functionality? If you comment it out, do you leave a note stating why it was removed and what it was originally intended to do? I ask mainly because I've done a lot of contract work for different places over the years and sometimes it's like excavating a tomb to find the actual code that is still being used. Why comment it out and leave it in the file if source control has a record of what used to be there? If you comment out a method do you also comment out/delete any methods that were exclusively used by that method? What do you think the best practices for this should be?

  • GWT Calendrical Calculations

    - by Kyle Hayes
    We have a GWT application that needs to display various holidays. Is there a library available to do these calendrical calculations? If not, we'll have to do our own that we can ingest a set of rules to. Cheers

  • Static vs Non Static constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • Force download through markup or JS

    - by mschoening
    Lets assume I have a file on a CDN (Cloud Files from Rackspace) and a static html page with a link to that file. Is there any way I can force download this file (to prevent it from opening in the browser -- for mp3s for example)? We could make our server read the file and set the corresponding header to: header("Content-Type: application/force-download") but we have about 5 million downloads per month so we would rather let the CDN take care of that. Any ideas?

  • Python - Code snippet not working on Python 2.5.6, using IDLE

    - by Francisco P.
    Hello, everyone I am using a piece of self-modifying code for a college project. Here it is: import datetime import inspect import re import sys def main(): # print the time it is last run lastrun = 'Mon Jun 8 16:31:27 2009' print "This program was last run at ", print lastrun # read in the source code of itself srcfile = inspect.getsourcefile(sys.modules[__name__]) f = open(srcfile, 'r') src = f.read() f.close() # modify the embedded timestamp timestamp = datetime.datetime.ctime(datetime.datetime.now()) match = re.search("lastrun = '(.*)'", src) if match: src = src[:match.start(1)] + timestamp + src[match.end(1):] # write the source code back f = open(srcfile, 'w') f.write(src) f.close() if __name__=='__main__': main() Unfortunately, it doesn't work. Error returned: # This is the script's output This program is last run at Mon Jun 8 16:31:27 2009 # This is the error message Traceback (most recent call last): File "C:\Users\Rui Gomes\Desktop\teste.py", line 30, in <module> main() File "C:\Users\Rui Gomes\Desktop\teste.py", line 13, in main srcfile = inspect.getsourcefile(sys.modules[__name__]) File "C:\Python31\lib\inspect.py", line 439, in getsourcefile filename = getfile(object) File "C:\Python31\lib\inspect.py", line 401, in getfile raise TypeError('{!r} is a built-in module'.format(object)) TypeError: <module '__main__' (built-in)> is a built-in module I'd be thankful for any solutions.

  • Disassembler that tracks what value is where

    - by Martin C. Martin
    So lately I've been looking at the disassembly of my C++ code, and having to manually track what's in each register, like this: 95: 48 8b 16 mov (%rsi),%rdx ; %rdx = raggedCross.sink 98: 48 8b 42 38 mov 0x38(%rdx),%rax ; %rax = sink.table 9c: 8b 4a 10 mov 0x10(%rdx),%ecx ; %ecx = sink.baseCol 9f: 48 8b 70 50 mov 0x50(%rax),%rsi ; %rsi = table.starts a3: 89 c8 mov %ecx,%eax ; %eax = baseCol a5: 83 c1 1c add $0x1c,%ecx ; %ecx = baseCol + 1 And so on. The comments are mine, added by hand, from looking up the offset of various fields (e.g. sink, table, baseCol, starts) in the C++ classes. It's straight forward to do, but tedius and time consuming: the perfect thing for a program to be doing. gdb seems to know the offset of various fields within a struct: I can do &((Table *)0x1200)-starts and it tells the the right address. So, this information is around. Is there some disassembler that can use this info to annotate the code for me? Failing that, I could write my own. Where does gdb get the offsets?

  • Learning networking fundamentals

    - by bplus
    Not having a CS degree has left large holes in my programming related knowledge. In particular I'd really like to learn some of the computer networking stuff I would have got in a good CS degree. The problem I really have is "not knowing what I don't know". So far I know I don't know anything about the following (as far as computer networks are concearned) -sockets -ports -internet protocol (the whole IP stack I keep hearing about). Can anyone add more to the list? Can anyone suggest a project (writing a toy web server?) Thanks in advance

  • Null reference but it's not?

    - by Clint Davis
    This is related to my previous question but it is a different problem. I have two classes: Server and Database. Public Class Server Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Private _databases As List(Of Database) Public Property Databases() As List(Of Database) Get Return _databases End Get Set(ByVal value As List(Of Database)) _databases = value End Set End Property Public Sub LoadTables() Dim db As New Database(Me) db.Name = "test" Databases.Add(db) End Sub End Class Public Class Database Private _server As Server Private _name As String Public Property Name() As String Get Return _name End Get Set(ByVal value As String) _name = value End Set End Property Public Property Server() As Server Get Return _server End Get Set(ByVal value As Server) _server = value End Set End Property Public Sub New(ByVal ser As Server) Server = ser End Sub End Class Fairly simple. I use like this: Dim s As New Server s.Name = "Test" s.LoadTables() The problem is in the LoadTables in the Server class. When it hits Databases.Add(db) it gives me a NullReference error (Object reference not set). I don't understand how it is getting that, all the objects are set. Any ideas? Thanks.

  • Encrypt ONE system directory?

    - by acidzombie24
    I dont want to encrypt my whole hard drive. But one app i ENJOY using stores my password in a not so secure way in the AppData folder. I would like to encrypt the folder. One note is the folder is inside my user/name directory. Maybe that will help or hinder the solution. I am fine with encrypting all of AppData if necessary. However i prefer not to encrypt C:\Users\NAME\ since it is heavily used by many apps. C:\Users\NAME\AppData\Local\APPNAME

  • jquery to php (wait for php script until result/finish)

    - by user354051
    Hi, I am executing a php call from javascript(jQuery), php sript is sending result back. The problem is that these php scripts are taking some time (milliseconds), and java script is not waiting for them to finish, thus variables are not getting initialized with correct values. The code is simple: $.get("php/validation.php",{'email':email},function(data){ // valid_email now contains true/false alert(data); if(data=="true"){ var valid_email = true;} }); The "alert" is printing true but value of valid_mail is recognized as "false" in the code below. Is there any other better way to call php scripts and wait for until they are not finished? Prashant

  • Web service accessing client database

    - by chupinette
    Hello all! I am new to web services and i have a question: Should a web service be able to access the client database? Sorry if i am not using the proper terms. Lets say i have a web service method called : GetCarDetails(string name) which will actually return details from car table. in this method i have an sql statement like SELECT * FROM car WHERE name = ?. In the client application, i have a textbox where i can input a name and a button on which when i click, fill a gridview. So im kinda confused, should the web service normally know that the client has a table called car?Please correct me if ive used the wrong terms. Thanks

  • How to apply CSS theme to only a specific jQuery-UI element?

    - by Thierry-Dimitri Roy
    I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

  • SQL - Two foreign keys that have a dependency between them

    - by Brian
    The current structure is as follows: Table RowType: RowTypeID Table RowSubType: RowSubTypeID FK_RowTypeID Table ColumnDef: FK_RowTypeID FK_RowSubTypeID (nullable) In short, I'm mapping column definitions to rows. In some cases, those rows have subtype(s), which will have column definitions specific to them. Alternatively, I could hang those column definitions that are specific to subtypes off their own table, or I could combine the data in RowType and RowSubType into one table and work with a single ID, but I'm not sure either is a better solution (if anything, I'd lean towards the latter, as we mostly end up pulling ColumnDefs for a given RowType/RowSubType). Is the current design SQL Blasphemy? If I keep the current structuree, how do I maintain that if RowSubTypeID is specified in ColumnDef, that it must correspond to the RowType specified by RowTypeID? Should I try to enforce this with a trigger or am I missing a simple redesign that would solve the problem?

  • Saving the modified contents of a pdf

    - by Anthony Webb
    I've got a form that I downloaded, I'd like to prefill some content on the form (this is easy using cfpdfform). Where it gets tricky is I would like to allow the user to modify the contents of that form, and then somehow have those modified contents accessible to me. I didnt build the source PDF so I dont know how to allow the user to "save" the new contents so they can be read. Any ideas on where I might start on this one?
