• Need an ASP.NET MVC long running process with user feedback

  - by Jason

  I've been trying to create a controller in my project for delivering what could turn out to be quite complex reports. As a result they can take a relatively long time and a progress bar would certainly help users to know that things are progressing. The report will be kicked off via an AJAX request, with the idea being that periodic JSON requests will get the status and update the progress bar. I've been experimenting with the AsyncController as that seems to be a nice way of running long processes without tying up resources, but it doesn't appear to give me any way of checking on the progress (and seems to block further JSON requests and I haven't discovered why yet). After that I've tried resorting to storing progress in a static variable on the controller and reading the status from that - but to be honest that all seems a bit hacky! All suggestions gratefully accepted!

• StyleCop 4.4 works inside VS.NET 2010 but not MSBuild command line

  - by Steve Michelotti

  We are seeing extremely strange results where StyleCop will correctly report violations when run from within Visual Studio 2010. However, when we run msbuild on the command line (e.g., "MSBuild.exe mySolution.sln") it reports "No violations encountered" when clearly there are the same violations as when we ran it within Visual Studio. Is this a bug in the latest release of StyleCop? Or in the 2010 integration? Is there anything you can tell me about possible differences with StyleCop executing from within VS.NET versus MSBuild command line? Thanks.

• Add columns to SqlWebEventProvider

  - by Julien N

  In an asp.net application, we'd like to use the SqlWebEventProvider to log any Event that occurs during the application lifetime. The problem is that we think that the table aspnet_WebEvent_Event doesn't provide enough columns and should log more information (we need to keep the Logged user). I'm aware that this information could be stored in the "Details" column but it wouldn't then be really simple to filter the results and build reports. So I'm searching for a simple solution to add a column. I wish I could derive SqlWebEventProvider but the methods used to build the stocked procedure parameters are private (PrepareParams() and FillParams()). Any simple solution that doesn't imply to rewrite the entire Provider class ?

• How to synchronize SQL Server 2008 database with SQL Server 2005 database?

  - by James McFarland

  I am using VS 2008 Team Suite and SQL Server 2008 in my development environment. I am deploying to a shared-host website with shared-host SQL Server 2005. I want to push changes from my development environment to my production host. I tried using Data | Schema Compare... and it reports to me that it does not support SQL Server 2008. What do people use for this (Besides Red-Gate tools - I use those at my day job, and they rock...this is a volunteer thing for my son's school)? I am looking for something very inexpensive if not free.

• Wrapping WPF UserControl inside VisualStudio Item Template

  - by karthik84

  I am currently started working on a project which will allow users to design reports inside visual studio. Previously, for my similar Winforms App, I had extended the IComponent (Component Class) and wrote our VS Like designer kind of custom control which will allow users to drag drop controls from the visual studio toolbox and then I export it as a VisualStudio C#&VB ItemTemplate. Now I am trying to recreate the same control using WPF considering its power, extensiblity. Could anyone shed some lights on this, on what would be the most preferable way of doing this ? Thanks in advance.

• Basic questions about SNMP

  - by David Hodgson

  Hi, I'm learning about SNMP, and writing some applications using it. I have some basic questions about the protocol: Do the agents store its state on the device itself? If there is a trap set on an agent, can you do a poll on the same OID to get the same information? Without using a mib file, is there a way to query a device for all of its information at once? If not, and you're writing your own customized manager, do you have to know the structure of what it reports up front? If you're setting up an agent to report, is there usually a way to control the frequency of how often it sends a trap? Or does it usually send a trap as often as some condition is satisfied?

• How to create a custom ADO Multi Dimensional Catalog with no database

  - by Alan Clark

  Does anyone know of an example of how to dynamically define and build ADO MD (ActiveX Data Objects Multidimensional) catalogs and cube definitions with a set of data other than a database? Background: we have a huge amount of data in our application that we export to a database and then query using the usual SQL joins, groups, sums etc to produce reports. The data in the application is originally in objects and arrays. The problem is the amount of data is so large the export can take 2 hours. So I am trying to figure out a good way of querying the objects in memory, either by a custom OLAP algorithm or library, or ADO MD. But I haven't been able to find an example of using ADO MD without a database behind it. We are using Delphi 2010 so would use ADO ActiveX but I imagine the ADO.NET MD is similar. I realize that if the application data was already stored in a database the problem would solve itself. Also if Delphi had LINQ capability I could query the objects and arrays that way.

• Qooxdoo REST JSON request problem - unexpected token and then timeout

  - by freiksenet

  Hello! I am learning Qooxdoo framework and I am trying to make it work with a small Django web service. Django webservice just returns JSON data like this: { "name": "Football", "description": "The most popular sport." } Then I use the following code to query that url: var req = new qx.io.remote.Request(url, "GET", "application/json"); req.toggleCrossDomain(); req.addListener("completed", function(e) { alert(e.getContent()); }); req.send(); Unfortunately when I execute the code I get unexpected token error and then request timeouts. Uncaught SyntaxError: Unexpected token : Native.js:91013011 qx.io.remote.RequestQueue[246]: Timeout: transport 248 Native.js:91013011 qx.io.remote.RequestQueue[246]: 5036ms > 5000ms Native.js:91013013 qx.io.remote.Exchange[248]: Timeout: implementation 249 JSLint reports that this is a valid JSON, so I wonder why Qooxdoo doesn't parse it correctly.

• Core Data (NSFetchedResultsController) displaying one row per section

  - by Urizen

  I have a CoreData application which uses NSFetchedResultsController. NSFetchedResultsController is useful in that it allows me to access the fetched objects more easily etc. but I find that I have problems with the following: I get a crash when I display a single row for each section (irrespective of the number of actual rows present) as a summary of the information in that section (e.g. showing a statistical analysis of the data contained in the fetched rows for that section). I understand that the NSFetchedResultsControllerDelegatemethods have to agree with the number of rows reported per section by the UITableView Delegate method but I would like to be able to fetch all of the records for each section without necessarily displaying each of the rows. The above causes me inconsistency crashes, when I try to insert or delete data for a section, which reports that the number of rows for each section is not as it should be given the number of insertions/deletions. Is there any way I can do what I'm trying to achieve? Thanks for any help.

• gcc std=gnu++0x option

  - by Neeraj

  Hi everyone, I need to compile a C++ code that uses std=gnu++0x option to the g++ compiler in the Makefile.am , As this option is compatible only with gcc 4.3 and above, the build crashes on my machine where i have gcc 4.2. What are my alternatives ? I tried removing that option from the Makefile.am but that reports some other error. Do i need to install gcc 4.3 or above? How can I do it in ubuntu hardy through apt-get ? Thanks.

• Get correct output from UTF-8 stored in VarChar using Entity Framework or Linq2SQL?

  - by jasonpenny

  Borland StarTeam seems to store its data as UTF-8 encoded data in VarChar fields. I have an ASP.NET MVC site that returns some custom HTML reports using the StarTeam database, and I would like to find a better solution for getting the correct data, for a rewrite with MVC2. I tried a few things with Encoding GetBytes and GetString, but I couldn't get it to work (we use mostly Delphi at work); then I figured out a T-SQL function to return a NVarChar from UTF-8 stored in a VarChar, and created new SQL views which return the data as NVarChar, but it's slow. The actual problem appears like this: “description†instead of “description”, in both SSMS and in a webpage when using Linq2SQL Is there a way to get the proper data out of these fields using Entity Framework or Linq2SQL?

• Project tracking/management tool

  - by Alvaro Rodriguez

  Which project tracking tool do you use? Does it allow programmers to bill hours worked to projects/tasks? Does it allow to track items promised vs. items delivered? Does it allow to forecast personnel needs when you have only a ballpark estimate of how many hours you are going to need for different task types? Does it integrate with your bug tracker? [Mantis] Does it integrate with your source control tool? [Subversion] Does it allow you to easily publish your schedule and current priorities to team members? Does it produce reports on any or all of the above? Am I even right in calling a tool that does those things a "Project tracking/management tool"? What does your tool have that makes you love it and use it every day? I don't really care about Gantt charts. I find Microsoft Project quite clunky for this needs (although I'm hardly an expert user).

• Importing war file into eclipse and build path problem

  - by Todd

  Hi, I am facing some weird problem when importing .war file into eclipse. The problem is, the build folder does not contain any necessary class folder. So when I try to set the build path, eclipse reports "Error while adding to build path. Reason: cannot nest output folder 'projectName/build/class' inside 'projectName/build'. From what I understand, 'build' folder is what classes get collected(as build version) right? I tried to ignore build path and just export .war file into tomcat server, but somehow servlet file keeps showing old code, which I changed in eclipse. So, I am thinking without proper build folder, exported .war will not contain modified servlect code.( I am sorry if this doesn't sound clear) What can I do to fix this problem? I already tried to create a whole new workspace and restarted eclipse several times and it didn't solve the problem.

• TFS Best Practices Project Hierarchy

  - by CWinKY

  I've recently installed and started using TFS. Mainly using for source repository initially and then will get into using the Work Item features. I'm moving from using Vault as repository and have some questions on best practices for setting up the project structure. My current structure from Vault is: Projects - CustomerName1 -- Application1 -- Application2 - CustomerName2 -- Application1 -- Application2 Can I have a smiliar structure in TFS? Is there any good documentation that has real examples and instructions on how to set this up? From what I see is all real basic and the books I have don't have real-life repository examples that mimic the structure I have. I have created a new Team Project called CustomerName1, then added other Team Projects, Application1, underneath CustomerName1. However, I lose on the Application1 the separate folders like Work Items, Documents, Reports, and Builds. So this doesn't appear set-up correctly. Thanks ...

• Grails Testing hickups

  - by egervari

  I have two testing questions. Both are probably easily answered. The first is that I wrote this unit test in Grails: void testCount() { mockDomain(UserAccount) new UserAccount(firstName: "Ken").save() new UserAccount(firstName: "Bob").save() new UserAccount(firstName: "Dave").save() assertEquals(3, UserAccount.count()) } For some reason, I get 0 returned back. Did I forget to do something? The second question is for those who use IDEA. What should I be running - IDEA's junit tests, or grails targets? I have two options. Also, why does IDEA say that my tests pass and it provides a green light even though the test above actually fails? This will really drive me nuts if I have to check the test reports in html every time I run my tests..... Help?

• How to run report in ReportViewer without having to click View Report button?

  - by user259286

  I've set up my report with params and it's value. When I run the page, it wants me to click the View Report button, but I need it to just run instead of interacting. Any ideas on this? Here's my code: rptViewer.Reset(); rptViewer.ProcessingMode = ProcessingMode.Remote; rptViewer.ServerReport.ReportServerUrl = new Uri("http://rptserver/reportserver"); rptViewer.ServerReport.ReportPath = "/Reports/My Report"; ReportParameterInfoCollection param = rptViewer.ServerReport.GetParameters(); ReportParameter[] rps = new ReportParameter[] {new ReportParameter(param[0].Name, param[0].ValidValues[0].Value)}; rptViewer.ServerReport.SetParameters(rps); IReportServerCredentials netCred = new CustomReportCredentials("me", "pwd", "domain"); rptViewer.ServerReport.ReportServerCredentials = netCred; rptViewer.ServerReport.Refresh(); rptViewer.SizeToReportContent = true; Thanks!

• Are there any programs to aid in the mass-editing of Visual SourceSafe checkin comments?

  - by Schnapple

  I know that in Visual SourceSafe you can go in and drill down to the history of an individual file and then drill down to an individual check-in and apply a comment to the check-in that way but that's tedious and time consuming - if you have a lot of files that were checked in at the same time and you want the same comment to apply to all of them this will take forever. I use the tool VSSReporter to generate reports of checkins and other stuff from VSS, but it cannot edit anything, only report on them. Are there any tools which will let you go back and retroactively apply comments to check-ins in an efficient and easy manner?

• synchronized block in JSP tag class

  - by Sudhakar

  Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())

• How to use Linq to group DateTime by month and days calculation

  - by Daoming Yang

  Hi all, I have two questions: First one: I have a order list and want to group them by the created month for the reports. Each order's created datetime will be like "2010-03-13 11:17:16.000" How can I make them only group by date like "2010-03"? Note: the DateCreated is the DateTime tpye The following code is not correct. var items = orderList.GroupBy(t => t.DateCreated.Month) .Select(g => new Order() { DateCreated = g.Key }) .OrderByDescending(x => x.OrderID).ToList(); Second one: Output the full months between two dates in C# If an user choose 2010-04-08 and 2010-06-04, I want to output the 2010-04-01 and 2010-06-30. I can always get the first day and last day of the months, but I want to find out some other options Many thanks. Many thanks.

• Use of COM object in IIS 7

  - by Wouter d.A.

  Hi all, I am currently moving an ASP.NET web-project from an IIS 6 to a IIS 7 hosting environment. Everything seems to be running OK, except my calls to a COM object. I can perfectly instantiate an object of the COM type, but when I call one of its methods, the IIS crashes. The event log reports an error code "0xc0000374", which indicates a heap corruption. When I run the application inside the visual studio development server, everything goes well and the COM object code gets executed without any errors. This is also the case when the application is hosted on an IIS 6 machine. I have looked through all settings of the IIS 7 and have not found anything configurable for COM objects, like security or ... I have been struggling with this for a while and I'm out of ideas. Does anyone have any experience deploying COM objects on IIS 7? Your help would be very appreciated!

• gcov and switch statements

  - by Matt

  I'm running gcov over some C code with a switch statement. I've written test cases to cover every possible path through that switch statement, but it still reports a branch in the switch statement as not taken and less than 100% on the "Taken at least once" stat. Here's some sample code to demonstrate: #include "stdio.h" void foo(int i) { switch(i) { case 1:printf("a\n");break; case 2:printf("b\n");break; case 3:printf("c\n");break; default: printf("other\n"); } } int main() { int i; for(i=0;i<4;++i) foo(i); return 0; } I built with "gcc temp.c -fprofile-arcs -ftest-coverage", ran "a", then did "gcov -b -c temp.c". The output indicates eight branches on the switch and one (branch 6) not taken. What are all those branches and how do I get 100% coverage?

• ReportViewer height issue. Hiding scrollbars.

  - by Tommy Jakobsen

  Hi, I'm using MSSQL 2005 Reporting Services and in this case I need to display some reports on an ASP.NET page using the ReportViewer control (I guess thats the only way, right?). The problem is that I can't get the property SizeToReportContent to work. When displaying the report, I get a vertical scrollbar because the report is too large. It looks like an iframe window. Searching on google it seems to be a bug. It can be fixed by setting AsyncRendering to false but I don't want that. I need another solution. I was wondering if it's possible to set the height on the report element using JavaScript after the report has been loaded? Or do you know of another solution? This is really annoying. Thanks in advance.
