• Does anyone know a better alternative to MS Excel's Solver?

  - by tundal45

  My company has to crunch a lot of data and part of the process involves running the solver and plotting a graph through resulting data points. Obviously there is a lot of copy and paste involved and the whole process is shaky, error prone and all round cluster-fudge. I was wondering if there was an alternative to the solver that can be used so that even if we have to use excel to plot the final graph, there will be a lot less data that needs to be copied and pasted back and forth. It would be great especially if the tool could be easily integrated into a .NET application but I am open to suggestions that may require a little bit of code-fu to get this to work. Thanks!

• Debug C# Windows Service

  - by Goober

  Scenario I've got a windows service written in C#. I've read all the google threads on how to debug it, but I still can't get it to work. I've run "PathTo.NetFramework\InstallUtil.exe C:\MyService.exe"........It said the install was successful, however when I run "Services.msc", The service isn't displayed at all, anywhere. If I go into Task Manager, there is a process called "MyService.vshost.exe".....pretty sure that's not it, because it's a service, not a process........Any suggestions and/or help? Greatly appreciated. Other I'm running VS2008.

• How do you update the aspnetdb membership IsApproved value?

  - by Matt

  I need to update existing users IsApproved status in the aspnet_Membership table. I have the code below that does not seem to be working. The user.IsApproved property is updated but it is not saving it to the database table. Are there any additional calls I need to make? Any suggestions? Thanks. /// <summary> /// Updates a users approval status to the specified value /// </summary> /// <param name="userName">The user to update</param> /// <param name="isApproved">The updated approval status</param> public static void UpdateApprovalStatus(string userName, bool isApproved) { MembershipUser user = Membership.GetUser(userName); if (user != null) user.IsApproved = isApproved; }

• What CPAN module can summarize error logs?

  - by mithaldu

  I'm maintaining some website code that will soon dump all its errors and warnings into a log file. In order to make this a bit more pro-active i plan to parse this log file daily, summarize the warnings and errors (i.e. count the occurrence of each specific one and group by either warning/error) and then email this to the devs on the project. This would likely admittedly be rather trivial with a hash and some further fiddling, I wondered if there is a suitable module on CPAN that i could use to do this task. It would either be one that summarizes specifically perl error/warnings logs or one that summarizes arbitrary text files. Any suggestions?

  Hi folks, Got a little issue where my client is pasting in content from Word into my little text editor in a CMS. The double quotes are coming back encoded in what looks like some form of UTF.

Here is the link to the page that spits out the dodgy characters, you can see the 'black diamonds of doom' which are causing the headaches. http://linq.milkbarstudios.com/news_detail.php?id=3 Any suggestions would be greatly accepted!

• How to get rid of the double scroll bar problem when using an iframe

  - by stu

  I've seen this problem on the web, and all the suggested solutions aren't working for me, so I thought I'd come here. I have a page that has an iframe. The top of the page is a dropdown menu, the rest of the page is the iframe. The idea like I'm sure everybody else does, is to have the menu stay stationary and the menu selection runs an application in the iframe. The contents of the iframe should scroll, but the page as a whole should not. I've tried putting the iframe width=height=100% inside a single table element also with width=height=100% but I get two scrollbars if I make the window too short vertically. Any suggestions?

• Accurate Timings with Oscilloscopes on PC

  - by Paul Bullough

  In the world of embedded software (firmware) it is fairly common to observe the order of events, take timings and optimise a program by getting it to waggle PIO lines and capturing their behavior on an oscilloscope. In days gone by it was possible to toggle pins on the serial and parallel ports to achieve much the same thing on PC-based software. This made it possible to capture host PC-based software events and firmware events on the same trace and examine host software/firmware interactions. Now, my new laptop ... no serial or parallel ports! This is increasingly the case. So, does anyone have any suggestions as to go about emitting accurate timing signals off a "modern" PC? It strikes me that we don't have any immediately programmable, lag-free output pins left. The solution needs to run off a laptop, so using add-on cards that only plug into desktops are not permitted.

• setting up log4j for gmail, does not recognize System.setProperty("mail.smtps.port", "587")

  - by Alex Le

  Hi I am trying to setup a smtpappender for log4j using gmail as the smtp host. I have read that the port number needs to be 465 or 587 (depending on tls or ssl) and that log4j for some reason doesnt allow a different port to be set inside log4j.properties configuration file. I have read that the best way of doing this would be to use System.setProperty which would change the default javaxmail port to gmail. However when I try to set the System.property entries the the default port still remains as 25 System.setProperty("mail.smtp.starttls.enable", "true"); System.setProperty("mail.smtp.port", "587"); I was wondering if someone could help me out, I am open to suggestions, I just need to smtpAppender to work for gmail, dont really care how to get it to work. Thanks

  I have a database in SQL server 2005 that originaly comes fom an old mainframe. All relations was set in the surrounding software and there are non i the database. I need to find the relations, not by field name but by actual contence in the registers.

There are some 200 registers with max 2 000 000 posts in any register. Does any one know of a software that can help me with this? The software I can find presuposes that relations are set in the database :(

• Drupal path alias not found

  - by Eric M

  Got a Drupal6 install, and I'm using a webform to collect some data. The webform has a path alias set on the edit page as 'contact_us'. The issue that I can't figure out (and hard to reproduce) is from time to time, some users end up on the page 'node/'. Seems like that is a possible failure trying to find the alias or system path. Any one seen this before? Any suggestions on some places to look or to why this is happening? Regards

• Web service reference location?

  - by Damien Dennehy

  I have a Visual Studio 2008 solution that's currently consisting of three projects: A DataFactory project for Business Logic/Data Access. A Web project consisting of the actual user interface, pages, controls, etc. A Web.Core project consisting of utility classes, etc. The application requires consuming a web service. Normally I'd add the service reference to the Web project, but I'm not sure if this is best practice or not. The following options are open to me: Add the reference to the Web project. Add the reference to the Web.Core project, and create a wrapper method that Web will call to consume the web service. Add a new project called Web.Services, and copy step 2. This project is expected to increase in size so I'm open to any suggestions.

• binary file formats: need for error correction?

  - by Jason S

  I need to serialize some data in a binary format for efficiency (datalog where 10-100MB files are typical), and I'm working out the formatting details. I'm wondering if realistically I need to worry about file corruption / error correction / etc. What are circumstances where file corruption can happen? Should I be building robustness to corruption into my binary format? Or should I wrap my nonrobust-to-corruption stream of bytes with some kind of error correcting code? (any suggestions? I'm using Java) Or should I just not worry about this?

• Online product demo environment for Windows applications

  - by Stefanos Tses

  I'm looking for a way to allow potential customers to try my application before they buy it. The product is a windows forms application that requires an SQL Server database to operate. Although I have a functional demo that the customer can install on their network, I want to make it easier for them by have them "play" with it at my environment. I remember Microsoft had (has?) something similar. I was testing Visual Studio a few years ago in a virtual environment where I was connecting to a server at Microsoft. Any suggestions? Thanks.

• Web Performance testing using VS2010 "Testing a file download"

  - by cheedep

  Hi All, I am trying out the VS 2010 testing tools for the first time. And I tried recording a web performance test and my actions had a file download implemented as in the KB article here http://support.microsoft.com/kb/812406 by streaming chunks of 10000 bytes. However my test is failing at the download saying "The response stream has been closed". Please help me understand why it is happening this way also any suggestions how you would test such a file download. My main aim was to see how the download was performing for a load test with Intercontinental 350kbps connection on files of about 30-50 MB. Thanks.

• How to parse a string into a nullable int in C# (.NET 3.5)

  - by Glenn Slaven

  I'm wanting to parse a string into a nullable int in C#. ie. I want to get back either the int value of the string or null if it can't be parsed. I was kind of hoping that this would work int? val = stringVal as int?; But that won't work, so the way I'm doing it now is I've written this extension method public static int? ParseNullableInt(this string value) { if (value == null || value.Trim() == string.Empty) { return null; } else { try { return int.Parse(value); } catch { return null; } } } Is there a better way of doing this? EDIT: Thanks for the TryParse suggestions, I did know about that, but it worked out about the same. I'm more interested in knowing if there is a built-in framework method that will parse directly into a nullable int?

• DRYing Search Logic in Rails

  - by Kevin Sylvestre

  I am using search logic to filter results on company listing page. The user is able to specify any number of parameters using a variety of named URLs. For example: /location/mexico /sector/technology /sector/financial/location/argentina Results in the following respectively: params[:location] == 'mexico' params[:sector] == 'technology' params[:sector] == 'financial' and params[:location] == 'argentina' I am now trying to cleanup or 'DRY' my model code. Currently I have: def self.search(params) ... if params[:location] results = results.location_permalink_equals params[:location] if results results = Company.location_permalink_equals params[:location] unless results end if params[:sector] results = results.location_permalink_equals params[:sector] if results results = Company.location_permalink_equals params[:sector] unless results end ... end I don't like repeating the searchs. Any suggestions? Thanks.

• Adding Boost Library to a C++ project in Windows Eclipse

  - by kingrichard2005

  I recently installed the Boost Library on Windows using the installer, I'm trying to link to the library in Eclipse but am not having any luck. I tried going through Project Properties - C/C++ Build - Settings - MinGW C++ Linker - Libraries and add the reference "boost_filesystem" according to this website: http://www.ferdychristant.com/blog//archive/DOMM-76JN6N , but I think that only applies to Unix variants. Everytime I compile I get the error: "cannot find -lboost_filesystem" . I've scoured the net, but cannot find a way to properly use Boost in Eclipse under a Windows platform. Any help or suggestions are appreciated.

• default webmail url workaround

  - by jan

  Hi, Is there a way or at least a workaround on masking default webmail urls or disabling access webmail urls so users will not be able to change their passwords? Website is PHP based and is using apache server under a shared hosting account. The thing is that http://domain.com/webmail will let users access the main panel where they can change their individual passwords. We do not need this. Most solutions point to changing httpd.conf which we are not allowed to change since this is on a shared hosting service. I'm looking for at least a workaround to this issue. How about disabling it through their browsers if my client is under a network server, this would be a decent workaround isn't it? or are there any more suggestions aside from this? Please help. This is my urgent issue. Thank you very much!

• C#: How do I get the path of the assembly the code is in?

  - by George Mauer

  Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code. Basically my unit test needs to read some xml test files which are located relative to the dll. I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else. Edit: People seem to be misunderstanding what I'm asking. My test library is located in say c:\projects\myapplication\daotests\bin\Debug\daotests.dll and I would like to get the "*c:\projects\myapplication\daotests\bin\Debug*" path. The three suggestions so far fail me when I run from the MbUnit Gui: Console.Out.Write(Environment.CurrentDirectory) gives c:\Program Files\MbUnit Console.Out.Write(System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location) gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll Console.Out.Write(System.Reflection.Assembly.GetExecutingAssembly().Location) gives the same as the previous

• Opencart not working

  - by user1588341

  I can go to http://www.sunnybrookfs.com/sstore/upload/ and it works awesome. But when I change the physical path in the basic settings for this website in the iis manager to the sstore/upload/ directory only text shows up. No images can be found or css style sheets. So basically www. sunnybrookfs. com/ goes to my xampp page, then I can access my OpenCart by going to http://www.sunnybrookfs.com/sstore/upload/. If I want www.sunnybrookfs.com to point to my store it does not work. Any suggestions? Thank you.

• How can I break into the development business scene if I'm the new kid on the block?

  - by Sergio Tapia

  I'm about 1 semester short of graduating from college with my Systems Engineer degree. I've started my own software development company here in a country in South America last week, and so far I managed to land myself a nice account. I have to build a simple enough program that will take me 6-7weeks to complete and I'll charge 2000$. 40% up front and the rest on completion. While this is great and I'm really excited about my first project (Hell it's a landmark for any professional!), I'm already setting my eye on landing projects that will be visible for other companies to see. I've spoken with many people in my trade around town and it seems there are two companies that manage the big accounts with other small companies scrounging around for the scraps. How can I break this so called fellowship that is pretty much a monopoly here? Any and all suggestions will be massively appreciated.
