• Are Visual Studio Setup Projects suitable for complex setups

  - by Robert

  Are "Visual Studio Setup" Projects suitable for complex setups in different versions? The application is rather large ( 500.000 lines of code) and is under continuous development. Every 6 to 10 month a new version gets released. We have multiple configuration files (INI and XML), registry keys, database migration scripts, etc. The application is in the progress of being migrated from VB6 to .NET . The old installer was build with Installshield. The feedback to Installshield is: Bad adaptability, bad reuse - thats way we are evaluating "Visual Studio Setup" as an alternative. Other products we consider: Free Solutions WiX NSIS Commercial Solutions Installshield (again..) Wise Advanced Installer sth. missing? Solutions we don't like to consider: Inno Setup (It just doesn't feel right)

• How to install plugins on Eclipse.

  - by Metz

  Hi, i know there already are other questions like this, but i could't find anything useful. And it's becoming such a painful issue.. I was trying to install ObjectAid on Eclipse 3.5.1. So, lets google, http://www.objectaid.com shows up. i added it to the repository list, then checked ObjectAid UML Explorer. It says: Cannot complete the install because one or more required items could not be found. Software being installed: ObjectAid Class Diagram 0.9.86 (com.objectaid.uml.feature.group 0.9.86) Missing requirement: ObjectAid Class Diagram 0.9.86 (com.objectaid.uml.feature.group 0.9.86) requires 'org.eclipse.draw2d 0.0.0' I've had a look into /opt/eclipse/plugins and i've found org.eclipse.draw2d_3.5.2.v20091126-1908, but i coudnt figure out how to install it. The operating system is Ubuntu. Thanks for any help.

• Cannot iterate of a collection of Anonymous Types created from a LINQ Query in VB.NET

  - by Atari2600

  Ok everyone, I must be missing something here. Every LINQ example I have seen for VB.NET anonymous types claims I can do something like this: Dim Info As EnumerableRowCollection = pDataSet.Tables(0).AsEnumerable Dim Infos = From a In Info _ Select New With {.Prop1 = a("Prop1"), .Prop2 = a("Prop2"), .Prop3 = a("Prop3") } Now when I go to iterate through the collection(see example below), I get an error that says "Name "x" is not declared. For Each x in Infos ... Next It's like VB.NET doesn't understand that Infos is a collection of anonymous types created by LINQ and wants me to declare "x" as some type. (Wouldn't this defeat the purpose of an anonymous type?) I have added the references to System.Data.Linq and System.Data.DataSetExtensions to my project. Here is what I am importing with the class: Imports System.Linq Imports System.Linq.Enumerable Imports System.Linq.Queryable Imports System.Data.Linq Any ideas?

• Can't open .svn/text-base/file.svn-base ?

  - by Earlz

  I'm using TortoiseSVN. I just made quite a few changes to my working copy and now I went to do a commit some of the files went through but at one file named Search.aspx.cs it says Commit failed (details follow): Can't open file 'C:\-----\trunk\.svn\text-base\Search.aspx.cs.svn-base': The system cannot find the file specified. I have tried doing a SVN update and SVN cleanup and nothing is restoring this file. I can't even create a diff because it gives a similar error about missing files. How do I fix this? What did I do to cause it?

• WPF 3D - Need help writing conversion methods between 2D and 3D (Point3DToPoint and PointAndZToPoint

  - by DanM

  I'm new to WPF 3D, so I may just be missing something obvious, but how do I convert from 3D to 2D and (for a given z location) from 2D to 3D? Specifically, I need two conversion methods: Point3DToPoint - If I have an (x, y, z) coordinate in the 3D world, how do I determine the (x, y) coordinate on the projected 2D surface. Method signature: public Point Point3DToPoint(Point3D point3D) PointAndZToPoint3D - If I have an (x, y) coordinate on the projected 2D surface and a z location in the 3D world, how do I determine the intersecting (x, y, z) coordinate in the 3D world? Method signature: public Point3D PointAndZToPoint3D(Point point, double z) I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. Note 1: I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date. Note 2: I'm currently using .NET 3.5, but if there are improvements in .NET 4.0 that would help me, please let me know.

• Explain difference in SQLIO numbers for RAID 0 versus RAID 5 over 6 disks

  - by markn

  When using the SQLIO benchmark tool on a 4-core Dell server with 6 15k 450GB (fast) drives, RAID 0, we found the max throughput was 2MB per second. But when configured as RAID 5, we get 30 MB per second. It seems that the RAID controller, Dell Perc 5i integrated controller, is maxing out the throughput per disk. With RAID 5, I expect to get a bump due to stripping, but not a 15x difference. Like good programmers, we suspect the hardware , but we could be missing something. This is predominately write traffic.

• How To debug Android app on Emulator using NetBeans IDE

  - by tobrien

  I recently downloaded the latest NetBeans IDE (for MACOSX) and imported/migrated a project over from the ECLIPSE environment. Everything looks, and works well... except that EMULATOR gets stuck "waiting for the debugger to attach." I tried "Attaching Debugger..." and set the PORT value to every case I've ever read about (8200, 8700, 5555, etc.) but the connection is refused. I am of the opinion that this is not the preferred way to start a debugging session in NetBeans for Android. What am I missing?

• Trouble Deploying .Net Framework 4 Website on IIS7

  - by Cyril Gupta

  Okay, I am trying to deploy a .Net framework 4 website on IIS7 server. I have already changed the application-pool's target framework to .Net 4, but the app is still showing me the error: "The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration" I am guessing that has something to do with the new feature of .Net4 that lets me have a compact Web config file. I think for some reason IIS7 is not happy with this. What can I do to deploy this app successfully or do I have to scale back to v3.5? I am sure there is a solution out there. Do you have any suggestions?

• Html.DropDownListFor not behaving as expected ASP.net MVC

  - by rybl

  Hello, I am new to ASP.net MVC and I am having trouble getting dropdown lists to work correctly. I have a strongly typed view that is attempting to use a Html.DropDownListFor as follows: <%=Html.DropDownListFor(Function(model) model.Arrdep, Model.ArrdepOptions)%> I am populating the list with a property in my model as follows: Public ReadOnly Property ArrdepOptions() As List(Of SelectListItem) Get Dim list As New List(Of SelectListItem) Dim arriveListItem As New SelectListItem() Dim departListItem As New SelectListItem() arriveListItem.Text = "Arrive At" arriveListItem.Value = ArriveDepart.Arrive departListItem.Text = "Depart At" departListItem.Value = ArriveDepart.Depart Select Case Me.Arrdep Case ArriveDepart.Arrive : arriveListItem.Selected = True Case Else : departListItem.Selected = True End Select list.Add(departListItem) list.Add(arriveListItem) Return list End Get End Property The Select Case works find and it sets the right SelectListItem as Selected, but when my view renders the dropdown list no matter what is marked as selected the generated HTML does not have anything selected. Am I obviously doing something wrong or missing something, but I can't for the life of me figure out what.

• Standalone GUI client for TFS 2010 Source Control

  - by Seth Reno

  I'm looking for a TFS 2010 GUI client that I can use outside of an IDE. I'm only looking to use the source control features in this case. I'm not talking about work items or build management. Ideally it would be a complete client that can be used on a machine where Visual Studio is not installed. Options I know about and why I'm not satisfied with them: TFS Power Tools - Windows Shell Extension Must have a working copy to use... see chicken or the egg Missing features: view history, branch / merge, revert SvnBridge TFS 2010 not yet supported Are there others that I don't know about?

• Require extended permissions in FBML pyfacebook app

  - by jlpp

  I'm trying to get my FBML canvas page to automatically prompt new app users for permission to publish_stream. Following Facebook's documentation I tried using the required_permissions argument to require_login. That is, I tried to use the pyfacebook require_login decorator like this: @facebook.require_login(required_permissions='publish_stream') as in: @decorator_from_middleware(FacebookMiddleware) @facebook.require_login(required_permissions='publish_stream') def canvas(request, template): ... Requesting extended permissions in a pyfacebook-based Facebook iFrame app has been discussed. Requesting extended permissions in an FBML app too. My objective is to require extended permissions in an FBML app. Am I missing something or can anyone suggest a workaround? Thanks.

• VSDBCMD returns "An unexpected failure occurred: Object reference not set to an instance of an objec

  - by Matt Wrock

  I have been succesfully using the command line database deployment tool VSDBCMD on my dev and test environments but the tool fails in our integration environmrnt. I am using the VS 2010 version of the tool. The servers have all of the prerequisites including: .net 4.0 sql server compact edition 3.5 sp1 (as well as the full edition of 2008) sql server 2008 server management objects sql server 2008 native client sql server system clr types msxml 6 all of the dependent DLLs included in: C:\Program Files\Microsoft SQL Server Compact Edition\v3.5\desktop*.dll C:\Program Files\Microsoft SQL Server Compact Edition\v3.5*.dll C:\Program Files (x86)\Microsoft Visual Studio 10.0\VSTSDB\Deploy**. The only reference to this error that I have been able to find has to do with a bug in the VS 2008 edition when the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0 key is missing. In my case the 10.0 version of the key exists. Has anyone else encountered this?

• MVC Dropdown List isn't binding to the model.

  - by Rod McLeay

  Hi, I am trying set up a simple dropdown list but I dont seem to be able to get it to bind to the Model. I am using Asp.Net MVC and nhibernate. My dropdown list is declared like so: <%= Html.DropDownListFor(model => model.Project, (IEnumerable<SelectListItem>)ViewData["Projects"], " -- Select -- ", new { name = "Project" })%> I set up the select list like so: ViewData["Projects"] = new SelectList(projectRepository.GetAll(), "EntityGUID", "Name", editEntity.Project); This seems to bind the select list to the Dropdown fine, but the SelectedValue is not set. it shows up as the default --- Select --- Also when I save this data, the dropdown does not bind to the model, I have to manually set the object like so to save it: entity.Project = projectRepository.GetById(new Guid(Request["Project"].ToString())); I believe I have take the correct messures to have this item bind directly to my model. Is there something I am missing here? Many thanks for your time, Rod

• The directory or file specified does not exist on the Web server.

  - by Guy

  I have a hybrid asp.net web forms / mvc application that I recently converted to .net 4 with mvc2. I have set-up that application to run on IIS 7.5 (on Windows 7) and the web forms part of the site is running okay but the MVC part is not. Whenever I try and access a page that needs to go through the routing engine I get HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. Module IIS Web Core Notification MapRequestHandler Handler StaticFile Error Code 0x80070002 I'm debugging this web site through VS2010 (so I've set-it-up to use IIS instead of Cassini) and when I put a break point in the Application_Start function it is never hit so the routes are never registered. When I put a break point in the Page_Load function in one of the aspx page code-behinds it gets hit. So it seems that the problem is that the route is not being registered. What am I missing?

• Giving a child window focus in IE8

  - by Andrew K

  I'm trying to launch a popup window from a Javascript function and ensure it has focus using the following call: window.open(popupUrl, popupName, "...").focus(); It works in every other browser, but IE8 leaves the new window in the background with the flashing orange taskbar notification. Apparently this is a feature of IE8: http://msdn.microsoft.com/en-us/library/ms536425%28VS.85%29.aspx It says that I should be able to focus the window by making a focus() call originating from the new page, but that doesn't seem to work either. I've tried inserting window.focus() in script tags in the page and the body's onload but it has no effect. Is there something I'm missing about making a focus() call as the page loads, or another way to launch a popup that IE8 won't hide?

• How to code Microsoft Excel "Shift Cells Up" feature in SQL

  - by user293249

  Take a simple table like below: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Home Base Row 2: Jeff || 7:00 AM || Virtual Base Row 3: Ryan || 6:30 PM || Test Base Now lets say that a single cell is deleted so the table now looks like this: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Row 2: Jeff || 7:00 AM || Virtual Base Row 3: Ryan || 6:30 PM || Test Base Notice that "Home Base" is missing. Now in excel you can delete the cell and shift the rest so the finished product looks like below: Column Headings: || Agent's Name || Time Logged In || Center || Row 1: Andrew || 12:30 PM || Virtual Base Row 2: Jeff || 7:00 AM || Test Base Row 3: Ryan || 6:30 PM || And you can see we are left with a blank cell last row. How do I code this procedure of shifting the cells up in SQL? I've been struggling on this problem for weeks! Thank you!

• ASP.NET MVC - ValidationMessageFor

  - by Murat

  Hi, I have asked this question on asp.net forums (http://forums.asp.net/t/1545006.aspx) but i had no valid answer therefore i'll try this here as well. I was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation. The below is the selectlist in my View <%=Html.DropDownListFor(model => model.SecurityQuestions[0].Question, "Some Security question", new { @class = "form_element_select" })%> The below code works fine and i can see the validation message came from modelstate. <%= Html.ValidationMessage("SecurityQuestions_0__Question")%> but this one does not work: <%= Html.ValidationMessageFor(model => model.SecurityQuestions[0].Question)%> SecurityQuestions is a generic list in my model public List<SecurityQuestion> SecurityQuestions { get; set; } Is this somewhat a bug in "ValidationMessageFor" or am i missing something here?

• Entity Framework - Using Transactions or SaveChanges(false) and AcceptAllChanges()?

  - by mark smith

  Hi there, I have been investigating transactions and it appears that they take call of them selves in EF as long as i pass false to savechanges.. SaveChanges(false) and if all goes well then AcceptAllChanges() Question is what is something goes bad, don't have to rollback? or as soon as the my method goes out of scope its ended? What happens to any indentiy columns that were assigned half way through the transaction.. i presume if somebody else added a record after mine before mine went bad then this means there will be a missing Identity value. Is there any reason to use standard "transactionScope" in code? ideas? - thanks

• Change webserver used by Flex in FlexBuilder to .NET Framework 3.5

  - by Simon_Weaver

  I just had to reformat and reinstall Flex and reconstruct a project. The problem is i am using ASP.NET as my server side technology and using LINQ in my files. The version of WebDev.Webserver.exe that FlexBuilder starts up is the wrong version so I get this error : Compiler Error Message: CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?) Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.3053 for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727 Copyright (C) Microsoft Corporation 2001-2005. All rights reserved. I know that changing to the latest version of ASP.NET / Framework will fix this - but I just can't figure out HOW to make that change in Flexbuilder. I cant even remember if i ever successfully did it before or if I just created a virtual directory in IIS7. Where would I change the version?

• Update EntitySet<> LINQ to SQL references

  - by gtas

  I know that when attaching an entity into a DataContext you have to also attach the related referenced objects manually too. While I'm attaching the EntityRef<'s everything works as expected and my entities are updated to the database. But i have noticed that a problem occurs while trying to attach the EntitySet<'s. I dont use rowversion columns so I'm attaching for every entity on the EntitySet< using original values. Tried just attaching AttachAll() the EntitySet< with no luck and no exception too. There is no exception but the update is not really happening. What am i missing?

• WMI Win32_OperatingSystem OSArchitecture field causes exception

  - by Andrew J. Brehm

  I am trying to get information on the version of Windows installed from WMI. Most fields work. I can get the operating system "Name" as well as the "Version", both are fields of the Win32_OperatingSystem object I have. But another field "OSArchitecture" generates an exception ("Not found"). strScope = "\\" + strServer + "\root\CIMV2" searcher = New ManagementObjectSearcher(strScope, "SELECT * FROM Win32_OperatingSystem") For Each mo In searcher.Get strOSName = mo("Name") strOSVersion = mo("Version") strOSArchitecture = mo("Architecture") strStatus = mo("Status") strLastBoot = mo("LastBootUpTime") Next Ignore the for each loop, I don't think it has anything to do with the field missing. The documentation says that the field ought to exist and is a String: http://msdn.microsoft.com/en-us/library/aa394239(VS.85).aspx Any ideas?

• Generating a KML heatmap from given data set of [lat, lon, density]

  - by Will Croft

  I am looking to build a static KML (Google Earth markup) file which displays a heatmap-style rendering of a few given data sets in the form of [lat, lon, density] tuples. A very straightforward data set I have is for population density. My requirements are: must be able to feed in data for a given lat, lon must be able to specific the given density of the data at that lat, lon must export to KML The requirements are language agnostic for this project as I will be generating these files offline in order to build the KML used elsewhere. I have looked at a few projects, most notably heatmap.py, which is a port of gheat in Python with KML export. I have hit a brick wall in the sense that the projects I have found to date all rely on building the heatmap from the density of [lat, lon] points fed into the algorithm. If I am missing an obvious way to adapt my data set to feed in just the [lat, lon] tuples but adjusting how I feed them using the density values I have, I would love to know!
