  • Are frameworks using byte-code generation creating leaky abstractions?

    - by Gabriel Šcerbák
    My point is, if you don't understand the abstraction of a framework, you can still decompile it and understand it, because you know the language e.g. Java. However, when byte-code generation happens, you have to understand even a lower level - JVM level byte-codes. I am really affraid of using any of such frameworks, which are many. Most of the time I think the reason for byte-code generation is simply lack of language features such as metaprogramming. Do you agree? What is your opinion and argument? How do you take over the problem with leaky abstractions in those frameworks?

  • Oracle get previous day records

    - by Phill Pafford
    Ok I think I'm getting the previous year instead of the previous day, but I need to previous day. SELECT TO_DATE(TO_CHAR(CURRENT_DATE, 'YYYY-MM-DD'),'YYYY-MM-DD') - 1 FROM Dual I'm comparing it to a datetime stamp in this format and wish to get all the rows from the previous day. YYYY-MM-DD HH:MM:SS So I'm trying something like this SELECT field,datetime_field FROM database WHERE datetime_field > TO_DATE(TO_CHAR(CURRENT_DATE, 'YYYY-MM-DD'),'YYYY-MM-DD') - 1

  • c# - SQL - speed up code to DB

    - by user228058
    I have a page with 26 sections - one for each letter of the alphabet. I'm retrieving a list of manufacturers from the database, and for each one, creating a link - using a different field in the Database. So currently, I leave the connection open, then do a new SELECT by each letter, WHERE the Name LIKE that letter. It's very slow, though. What's a better way to do this? TIA

  • Python: Get items at depth? (set library?)

    - by Mark
    I have a nested list something like this: PLACES = ( ('CA', 'Canada', ( ('AB', 'Alberta'), ('BC', 'British Columbia' ( ('van', 'Vancouver'), ), ... )), ('US', 'United States', ( ('AL', 'Alabama'), ('AK', 'Alaska'), ... I need to retrieve some data out of it. If depth is 0 I need to retrieve all the countries (and their codes), if depth == 1, I need to retrieve all the states/provinces, if depth == 2 I need to retrieve all the cities... and so forth. Is there some set library for doing stuff like this? Or can someone point me in the right direction? I started coding up a solution only to realize it wouldn't work for levels deeper than 1 because you have to go in and out of each list...

  • Refactoring many nested ifs or chained if statements

    - by Icarus
    Hi, I have an object with large number of similar fields (like more than 10 of them) and I have to assign them values from an array of variable length. The solution would be either a huge nested bunch of ifs based on checking length of array each time and assigning each field OR a chain of ifs checking on whether the length is out of bounds and assigning each time after that check. Both seem to be repetitive. Is there a better solution ?

  • VB - Convert Web Site to Web Application

    - by Dave
    Hi This is my first time doing VB :-) I've inherited a web site, which I've converted into a web application in VS2008. The conversion has worked for everything except a Gallery control. The compile error I'm getting is: Type 'Gallery' is not defined in file: gallery_oct07.aspx.designer.vb Option Strict On Option Explicit On Partial Public Class gallery_oct07 '''<summary> '''Gallery1 control. '''</summary> '''<remarks> '''Auto-generated field. '''To modify move field declaration from designer file to code-behind file. '''</remarks> Protected WithEvents Gallery1 As Global.Gallery End Class with squiggly lines under Global.Gallery. The gallery_oct07.aspx.vb is: Partial Class gallery_oct07 Inherits System.Web.UI.Page End Class Gallery.ascx is: <%@ Control Language="C#" AutoEventWireup="true" Codebehind="Gallery.ascx.cs" Inherits="WebApplication1.Gallery"%> <asp:Repeater runat="server" ID="rptGallery"> <HeaderTemplate> <ul class='<%#CssClass%>'> </HeaderTemplate> <ItemTemplate> <li><a href='<%#ImageFolder + Eval("Name") %>' class="thickbox" rel="gallery"><img src='<%#ImageFolder + "thumb/" + Eval("Name") %>' /></a></li> </ItemTemplate> <FooterTemplate> </ul></FooterTemplate> </asp:Repeater> and the code behind is: using System; using System.IO; namespace WebApplication1 { public partial class Gallery : System.Web.UI.UserControl { public string _ImageFolder; public string ImageFolder { get { return _ImageFolder; } set { _ImageFolder = value; } } private string _cssClass = "gallery"; public string CssClass { get { return _cssClass; } set { _cssClass = value; } } protected void Page_Load(object sender, EventArgs e) { DirectoryInfo dir = new DirectoryInfo(MapPath(ImageFolder)); FileInfo[] images = dir.GetFiles("*.jpg"); rptGallery.DataSource = images; rptGallery.DataBind(); } protected void Page_PreRender(object sender, EventArgs e) { } } } The feels like a namespace issue.. My project namespace is WebApplication1. Cheers!

  • How do I get selected background color from SecondView to pass to FirstView?

    - by rob
    I am going insane! This is a simple app with two Views. FirstView is a text field with info button to flip to SecondView. In SecondView I have 6 buttons for background color choice. When button is pushed the color of background changes perfectly but cannot make it also change background color for FirstView. Any help would be GREAT! Thanks! I am using Objective C class working on a iPhone app. Sorry new at this. The SecondView acts almost like a settings page in the fact that when a button is pushed the background color changes to the button color. I need it so when I push the "back" button to go back to FirstView the background color has also changed to that color choice. Been thru sooooooooo many tutorials and codes that now I am totally lost......... Thanks again!

  • Connection to DB2 in Python

    - by Mestika
    Hi, I'm trying to create a database connection in a python script to my DB2 database. When the connection is done I've to run some different SQL statements. I googled the problem and has read the ibm_db API (http://code.google.com/p/ibm-db/wiki/APIs) but just can't seem to get it right. Here is what I got so far: import sys import getopt import timeit import multiprocessing import random import os import re import ibm_db import time from string import maketrans query_str = None conn = ibm_db.pconnect("dsn=write","usrname","secret") query_stmt = ibm_db.prepare(conn, query_str) ibm_db.execute(query_stmt, "SELECT COUNT(*) FROM accounts") result = ibm_db.fetch_assoc() print result status = ibm_db.close(conn) but I get an error. I really tried everything (or, not everything but pretty damn close) and I can't get it to work. I just need to make a automatic test python script that can test different queries with different indexes and so on and for that I need to create and remove indexes a long the way. Hope someone has a solutions or maybe knows about some example codes out there I can download and study. Thanks Mestika

    I have a small app with Category model and want to make a required foreign key referencing it from Photologue Gallery model. What's the right approach?

  • Display an Image using C# in Web Application

    - by Josh
    Hello again, I have a Web Application that I built a C# class in that generates a Report. This report takes nearly 40 seconds to generate because it searches hundreds of folders for certain files. So I was hoping there was a way to display a "Loading.." icon as this report is generating. I have a gif stored in my Images folder that would be perfect. The research that I've done at this point mostly talks about picturebox's and image controls that can hold the image but I was hoping there was just a way of displaying the image above the report while its being created. The Web Application is from a Web ADF Geocortex website and again I created a C# class that generates this report. Below is some code that may help. /// <summary> /// Generates HTML for the current report using the data in /// the given table. /// </summary> /// <param name="reportLayers">The layers to include in the report.</param> /// <returns> public override string GenerateReportHtml(List<ReportLayer> reportLayers) { StringBuilder htmlString = new StringBuilder(); StringWriter stringWriter = new StringWriter(htmlString); HtmlTextWriter writer = new HtmlTextWriter(stringWriter); string holdAPI = ""; List<string> exclusions = GetExcludedFields(); foreach (ReportLayer layer in reportLayers) { string[] strFiles = null; Boolean val = false; if (layer.Layer.Name == "Bottom Hole Location (OP)") writer.RenderBeginTag(HtmlTextWriterTag.P); // <p> writer.RenderBeginTag(HtmlTextWriterTag.Strong); // <strong> writer.Write(layer.Layer.Name); writer.RenderEndTag(); // end </strong> writer.RenderEndTag(); // end </p> writer.WriteBreak(); // <br /> foreach (ReportFeature feature in layer.ReportFeatures) { // each feature will be in a table writer.RenderBeginTag(HtmlTextWriterTag.Table); // <table> foreach (ReportField field in feature.ReportFields) { string fieldName = field.Alias; if (!exclusions.Contains(fieldName)) {

  • Rails: Generated tokens missing occasionally

    - by Vincent Chan
    We generate an unique token for each user and store it on database. Everything is working fine in the local environment. However, after we upload the codes to the production server on Engine Yard, things become weird. We tried to register an account right after the deploy. It is working fine and we can see the token in the db. But after that, when we register new accounts, we cannot see any tokens. We only have NULL in the db. Not sure what caused this problem because we can't re-produce this in the local machine. Thanks for your help.

  • How can I make an SQL statement that finds unassociated records?

    - by William Calleja
    I have two tables as follows: tblCountry (countryID, countryCode) tblProjectCountry(ProjectID, countryID) The tblCountry table is a list of all countries with their codes and the tblProjectCountry table associates certain countries with certain projects. I need an SQL statement that gives me a list of the countries with their country code that do NOT have an associated record in the tblProjectCountry table. so far I got to here: SELECT tblCountry.countryID, tblCountry.countryCode FROM tblProjectCountry INNER JOIN tblCountry ON tblProjectCountry.countryID = tblCountry.countryID WHERE (SELECT COUNT(ProjectID) FROM tblProjectCountry WHERE (ProjectID = 1) AND (countryID = tblCountry.countryID)) = 0 The above statement parses as correct but doesn't give the exact result I'm looking for. Can anyone help?
