• SQL Server 2008 Management Studio Activity Monitor

  - by Angelo

  Hi, I tried to turn on the Activity Monitor using SQL Server 2008 Management Studio (SSMS) through the options window of the application (Tools | Options | Environment | General | At Startup). I restarted SSMS and I am getting the following message: "This operation does not support connections to Microsoft SQL Server Standard Edition version 8.00.2249." I need to be able to monitor the processes and activities inside the database since I am investigating a particular application which takes a lot of time in its database data retrieval access and I am thinking it may be due to some locks or some processes. How do I resolve this? Inputs highly appreciated. Thanks.

• Could not retrieve data from URL

  - by user1655065

  I have a lot of websites which are using the same CMS, and they are hosted in 3 seperated servers, only one of this servers has a problem with retrieving the title, description, and the image of any url, and in the FaceBook debugger I get this error: Could not retrieve data from URL. From previous questions, I read that the reason may be an HTML error, but as I said before on other servers there is no problem using the same CMS. You can try putting this URL for example in the debugger: http://www.shaharah.net/2010/news-10054.htm Also, other websites on the same server which are using another CMS, or is just HTML pages are also not retrieved. Thanks. Best regards, Aws Aleryani

• Multiple column foreign key contraints

  - by eugene4968

  I want to setup table constraints for the following scenario and I’m not sure how to do it or if it’s even possible in SQL Server 2005. I have three tables A,B,C. C is a child of B. B will have a optional foreign key(may be null) referencing A. For performance reasons I also want table C to have the same foreign key reference to table A. The constraint on table C should be that C must reference its parent (B) and also have the same foreign key reference to A as its parent. Anyone have any thoughts on how to do this?

• Authorization/Licensing of Webservice

  - by Burhan

  I have developed a web service which accepts the login credentials from the XML message passed to it. I have concerns over this method as the developer who consumes the service can easily share the login credentials and my service can be called from some other application that uses the same credentials. Is there any way that I can issue a 'license' to some specific applications? So that, even if credentials are shared among the consuming apps, only authorized ones can successfully consume the service. P.S: I thought about implementing IP restrictions but that doesn't serve the purpose as we may have different applications installed on a same server (we do have such a scenario implemented).

• Display continious dates in Pivot Chart

  - by Douglas

  I have a set of data in a pivot table with date times and events. I've made a pivot chart with this data, and grouped the data by day and year, then display a count of events for each day. So, my horizontal axis goes from 19 March 2007 to 11 May 2010, and my vertical axis is numeric, going from zero to 140. For some days, I have zero events. These days don't seem to be shown on the horizontal axis, so 2008 is narrower than 2009. How do I display a count of zero for days with no events? I'd like my horizontal axis to be continuous, so that it does not miss any days, and every month ends up taking up the same amount of horizontal space. (This question is similar to the unanswered question here, but I'd rather not generate a table of all the days in the last x number of years just to get a smooth plot!)

• fstream file I/O question

  - by Konrad

  Hi, I am trying to work out if I need to call close on a fstream object if the intial open failed. i.e. std::fstream strm; strm.open( "filename" ); if( ! strm.fail() ) { // Do something strm.close(); // [1] } strm.close(); // [2] Where should close be called here - should it always be called [2] or only if the open succeeds[1]? I may be going over the top here, but coming from the Windows API way of typically doing this I have CloseHandle( ... ); embedded in my mind :-)

• Displaying conditional amount of fields in UI (Android)

  - by Sochin

  I am using layout xml documents for my ui controls. I need to create and remove these controls (input fields) on the fly, based on how many results I get back from my database. For each group, there can be 0..* fields and these are prepopulated from the database. Also, it would be good if I can invoke a method to create an additional field; something like the address book, where you can click + or - to add or remove a phone or other detail. In a "psuedo" style, I'm guessing something like this: Check database - How many of X are there [y]? Create Y fields. The user may then add new fields, so once I click submit i need to apply all of that to database. Any examples or hints greatly welcomed. Hope this make sense! :)

• Delphi : What is the best way for passing data between forms?

  - by Flom Enol

  It may seem a little newbie, but I really have got problem with it. I have a form (not the main one)for getting many different data form the user and I want to pass it to a manager class for creating an object with these. The problem is that I can't have this class to use the other unit (getting circle uses) and also it doesn't have access to the manager class instance (which is in main form). So, what shall I do? I've already considered using public variable but I have a bad feeling about it (regarding OOD patterns). Any ideas? thanks in advance.

• MySQL look for missing ratings

  - by Dustin

  Hopefully I can ask this without being confusing. I am a photographer and I am having some of our clients rate pictures that we have taken. We have hundreds of pictures in our portfolio that they may be rating. What I want to do is ask our clients to rate pictures again, but only show them the pictures they haven't yet rated. I currently have three tables: one that stores the actual ratings, one that stores the pictures (or location of each picture), and one that stores the information about the rater. I'm using codeigniter for my db management, if that helps at all. What I have so far is this: "SELECT * FROM ratings LEFT JOIN portfolio ON ratings.portfolioid = portfolio.portfolioid" This will give me a row for each rating, but won't show me where a rating is missing for a picture. Thanks in advance!

• ASP.NET Template Selector/Builder - Dynamic CMS

  - by Ugene

  I am currently building my own CMS for various reasons that could take a long to explain... However i am looking for a dynamic solution to create templates for pages within the CMS and all areas must be editable via the administration area, maybe large text areas broken into multiple areas, text and image area on a page etc. Following on from the above i would like to create the following: Create a new page (selecting a pre-defined template like below) http://img525.imageshack.us/img525/9872/nestedpages.png and then upon editing the page it would have created as many text editors required for each editable region or a file upload control for an image area for example. i am thinking of using nested masterpages for the design elements, just unsure the best-practice way to achieve the above (db structure etc) I somehow hope this provides enough information but are happy to answer any questions you may have. Thanks

• viewForHeaderInSection - create header that would display properly in all cases

  - by sha

  I have an interesting problem/question and i'm not sure if it is even doable. So I have a custom header view for regular UITableView. But it's transparent and it doesn't fill fill table width. So it displayed properly when table is scrolled and this header view is displayed above cell content (sticked to the top). But when same header is displayed between two sections down - it looks ugly, because it's transparent and it's either displayed above black rectangle or above table background. I was wondering is there way to customize header view for when it's stick to the top and when it's not. Or... may be it's possible to specify what needs to be displayed underneath header view when it's between sections. Something like sectionSeparatorView?

• No response in Eclipse: File ->Import->Existing Projects into Workspace

  - by Hula

  I'm trying to import one of the GWT samples into Eclipse by following the instructions below. But when I browse to the directory containing the "Hello" sample and uncheck "Copy projects into workspace", the Finish button is grayed out, preventing me from completing the import. Any ideas why? -- Option A: Import your project into Eclipse (recommended) -- If you use Eclipse, you can simply import the generated project into Eclipse. We've tested against Eclipse 3.3 and 3.4. Later versions will likely also work, earlier versions may not. In Eclipse, go to the File menu and choose: File - Import... - Existing Projects into Workspace Browse to the directory containing this file, select "Hello". Be sure to uncheck "Copy projects into workspace" if it is checked. Click Finish.

• Word VBA: How to know if the actual save operation is completed?

  - by Edwin

  Hi, I am having a problem with the Document.SaveAs method in Word VBA with large Word documents, it seems that the save operation is asynchronous, ie. after calling SaveAs it returns immediately, but with large Word documents the actual save operation may not has been completed and it's in progress in another thread. So what I want to ask is that if there is a way to detect if the actual save operation is in progress or finished? PS. I use Delphi to call the automation interface of Word, if it means something in discussing this problem, but I don't' think so? Thank you in advance.

• Using ManagementClass.Getinstances() from IronPython

  - by Leo Bontemps

  I have an IronPython script that looks for current running processes using WMI. The code looks like this: import clr clr.AddReference('System.Management') from System.Management import ManagementClass from System import Array mc = ManagementClass('Win32_Processes') procs = mc.GetInstances() That last line where I call the GetInstances() method raises the following error: Traceback (most recent call first): File "<stdin>", line 1, in <module> SystemError: Not Found I am not understanding what's not being found?!? I believe that I may need to pass an instance of ManagementOperationObserver and of EnumerationOptions to GetInstance() however, I don't understand why that is, since the method with the signature Getinstance() is available in ManagementClass.

• Is there a way to include commas in CSV columns without breaking the formatting?

  - by editor

  I've got a two column CSV with a name and a number. Some people's name use commas, for example "Joe Blow, CFA." This comma breaks the CSV format, since it's interpreted as a new column. I've read up and the most common prescription seems to be replacing that character, or replacing the delimiter, with a new value (e.g. "this|that|the, other"). I'd really like to keep the comma separator (I know excel supports other delimiters but other interpreters may not). I'd also like to keep the comma in the name, as "Joe Blow| CFA" looks pretty silly. Is there a way to include commas in CSV columns without breaking the formatting, for example by escaping them?

• How can I use git to stage only one line in a file for commit, all from a script?

  - by Sandy

  I'm writing a simple pre-commit git hook that updates the year in copyright headers for files that are staged for commit. After modifying the line with the copyright, I would like the hook to stage that line so that it is part of the commit. It can't just git add the whole file, because there may be other pre-existing changes in there that shouldn't be staged. I don't see any options in the git add manual the let you stage specific lines. I figure I could git stash save --keep-index, apply my change, git add the file, and then git stash pop, but that seems rather crude. Any better approaches?

• How do I run D3D9 programs (that have already been compiled) on a machine without the SDK?

  - by rambo

  I have a simple 3D application programmed in C++ and D3D9 using MSVC++ 2008 Express. Some weeks ago, I had to format my hard disk, so the DirectX SDK is not currently installed. However, I found that the exe file that I found in my "Debug" folder for the project does not run. The error it gives is: "This application has failed to start because d3dx9d_38.dll was not found. Re-installing the application may fix this problem." Of course, it worked after I installed the SDK. Then I compiled a "release build" thinking that that was the solution. Then I uninstalled the SDK and tried to run the .exe file. Still gave me the error. So how does one make such .exe files run on machines without the SDK?

• Debugging ASP.NET in VS

  - by negligible

  A lot of what I'm doing at the moment is figuring out other peoples code and adding or adapting functions, so currently I am debugging more than I am writing code of my own. I'm still new to this, Junior Developer, and I am always finding new ways to improve what I am doing. For example I recently found This Guide which had some excellent tips, such as overriding the ToString() method in your classes so children are readable from their parents. So I am looking for any other tips or tricks to make my debugging more efficient, as I recognise it as a big part of programming, that you more experienced programmers may have picked up or found. Anything appreciated, I can read websites just fine so no need to explain it yourself if you have a good link!

• Is there any way to view PHP code (the actual code not the compiled result) from a client machine?

  - by Columbo

  This may be a really stupid question...I started worrying last night that there might be someway to view PHP files on a server via a browser or someother means on a client machine. My worry is, I have an include file that contains the database username and password. If there were a way to put the address of this file in to a browser or some other system and see the code itself then it would be an issue for obvious reasons. Is this a legitimate concern? If so how do people go about preventing this?

• Creating installers in .net

  - by Manish

  I want to create a installer which would just dump few files and folders at a location specified by user. But the problem is these files are required to be picked up from a fixed source folder and then the installer is build. Also, these files may change any time and then again a new version of the installer is required to be created. I want to do this in .Net using Setup and Deployment project. I'm not sure how to do this. Do I need to create another class library project with a Setup Poject? Does anyone has any idea?

• Using Rails, how can I set my primary key to not be an integer-typed column?

  - by Rudd Zwolinski

  I'm using Rails migrations to manage a database schema, and I'm creating a simple table where I'd like to use a non-integer value as the primary key (in particular, a string). To abstract away from my problem, let's say there's a table employees where employees are identified by an alphanumeric string, e.g. "134SNW". I've tried creating the table in a migration like this: create_table :employees, {:primary_key => :emp_id} do |t| t.string :emp_id t.string :first_name t.string :last_name end What this gives me is what seems like it completely ignored the line t.string :emp_id and went ahead and made it an integer column. Is there some other way to have rails generate the PRIMARY_KEY constraint (I'm using PostgreSQL) for me, without having to write the SQL in an execute call? NOTE: I know it's not best to use string columns as primary keys, so please no answers just saying to add an integer primary key. I may add one anyway, but this question is still valid.

• How to send files along with parameters over http

  I am trying to send a zipfile from my android application to our server and I keep getting a 411 length required error. Here is the code that I am using to do that.

• Loading jQuery multiple times in the same page

  - by Winaji

  I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.

• Aside from performance concerns, is Java still chosen over Groovy/JRuby etc.?

  - by yar

  [This is an empirical question about the state-of-the-art: I am NOT asking if Java is cooler or less cool than the dynamic languages that work in the JVM.] Aside from cases where performance is a main decision factor, do companies/developers still willingly chose Java over Groovy, JRuby or JPython? Personal Note: The reason I am asking is that, while I do some subset of my professional work in Ruby (not JRuby, for now), in my personal projects I use Java. While I have written non-trivial apps in Groovy, I prefer Java, but I wonder if I should just get over it and do everything in Groovy. I like Java because I feel that static typing saves me time and aids refactoring. (No, I am not familiar with Scala.) However, I feel that this very empirical, on-topic programming question may inform my decision.

• Project Reference added to one of the projects in the same solution appears broken in another solution

  - by CSharpLearner

  I have couple of solutions. In the first solution I have many projects. One of the project named 'A' has a project reference of another project 'B' of the same solution. In second solution, the project 'A' is added but not the project 'B'. Both the solutions build successfully. However, in second solution, reference of B added in the project A, appears broken. Why? Now, in first solution, instead of adding Project reference of B into A, i simply add a 'file reference' of B's DLL (which is copied at the common output directory created for all the projects) into A. Now the reference appears broken in both the solution even though both the solutions are built successfully. May I know what should I do when I have such a scenario?
