  • Learning by doing (and programming by trial and error)

    - by AlexBottoni
    How do you learn a new platform/toolkit while producing working code and keeping your codebase clean? When I know what I can do with the underlying platform and toolkit, I usually do this: I create a new branch (with GIT, in my case) I write a few unit tests (with JUnit, for example) I write my code until it passes my tests So far, so good. The problem is that very often I do not know what I can do with the toolkit because it is brand new to me. I work as a consulant so I cannot have my preferred language/platform/toolkit. I have to cope with whatever the customer uses for the task at hand. Most often, I have to deal (often in a hurry) with a large toolkit that I know very little so I'm forced to "learn by doing" (actually, programming by "trial and error") and this makes me anxious. Please note that, at some point in the learning process, usually I already have: read one or more five-stars books followed one or more web tutorials (writing working code a line at a time) created a couple of small experimental projects with my IDE (IntelliJ IDEA, at the moment. I use Eclipse, Netbeans and others, as well.) Despite all my efforts, at this point usually I can just have a coarse understanding of the platform/toolkit I have to use. I cannot yet grasp each and every detail. This means that each and every new feature that involves some data preparation and some non-trivial algorithm is a pain to implement and requires a lot of trial-and-error. Unfortunately, working by trial-and-error is neither safe nor easy. Actually, this is the phase that makes me most anxious: experimenting with a new toolkit while producing working code and keeping my codebase clean. Usually, at this stage I cannot use the Eclipse Scrapbook because the code I have to write is already too large and complex for this small tool. In the same way, I cannot use any more an indipendent small project for my experiments because I need to try the new code in place. I can just write my code in place and rely on GIT for a safe bail-out. This makes me anxious because this kind of intertwined, half-ripe code can rapidly become incredibly hard to manage. How do you face this phase of the development process? How do you learn-by-doing without making a mess of your codebase? Any tips&tricks, best practice or something like that?

  • Technique to Solve Hard Programming logic

    - by Paresh Mayani
    I have heard about many techniques which are used by developer/software manager to solve hard programming logic or to create flow of an application and this flow will be implemented by developers to create an actual application. Some of the technique which i know, are: Flowchart Screen-Layout Data Flow Diagram E-R Diagram Algorithm of every programs I'd like to know about two facts: (1) Are there any techniques other than this ? (2) Which one is the most suitable to solve hard programming logic and process of application creation?

  • Collaborative work (small team) - Best practices

    - by LEM01
    I'm currently working in a very small team of programmers (2-3) and I'm looking for advices/best practices on how to organise our work. We're all working on the same application using PHP. Today we're kind of all working on our way. Today situation: List item that have to be worked on by each dev 1/week. What has to be done is defined at a high functional level (ex: Build the search engine for this product..) Commit / merge our individual branches (git) every week before the next meeting No real dev rules, no code review No test written (aouutch) Problems faced: Code quality issue: discovering someone else code is sometime tough (inline, variable+function+class names, spaces, comments..) Changes in already existing classes (impact on someone else work) Responsibility of each dev unclear: after getting someone else code and discover something messy, should I make the change? Should he make the change? How to plan those things,... What I'm looking for: Basically I'm looking into structuring the way we develop things in order to avoid frustration and improve overall quality. How to define coding standards (naming convention, code rules...)? Do you you any validation script to make sure code is valid before committing? Do you think that defining an architect role in the team is needed? Someone that would actually define what has to be developed during the next phase. By defining interfaces or class descriptions that have to be written. (Does it make sense in such a small team?) Today we're losing time into understanding what others did or tried to do, we're also losing time in discussion like "you should have done it that way! Why is this class doing that and not that..? Shouldn't we have a embedded class rather that this set of data...". I'm looking into a work process, maybe with more defined responsibilities and process in order to improve our performance. If you have experience, advices, best practices or anything to share that we could benefit from it will be much appreciated! Thanks a lot for your time!

  • SQL Server 2008 error message from stored procedure

    - by George2
    Hello everyone, I am using SQL Server 2008 Enterprise. When we met with such error message from stored procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in advance, George

  • When should I use a Process Model versus a Use Case?

    - by Dave Burke
    This Blog entry is a follow on to https://blogs.oracle.com/oum/entry/oum_is_business_process_and and addresses a question I sometimes get asked…..i.e. “when I am gathering requirements on a Project, should I use a Process Modeling approach, or should I use a Use Case approach?” Not surprisingly, the short answer is “it depends”! Let’s take a scenario where you are working on a Sales Force Automation project. We’ll call the process that is being implemented “Lead-to-Order”. I would typically think of this type of project as being “Process Centric”. In other words, the focus will be on orchestrating a series of human and system related tasks that ultimately deliver value to the business in a cost effective way. Put in even simpler terms……implement an automated pre-sales system. For this type of (Process Centric) project, requirements would typically be gathered through a series of Workshops where the focal point will be on creating, or confirming, the Future-State (To-Be) business process. If pre-defined “best-practice” business process models exist, then of course they could and should be used during the Workshops, but even in their absence, the focus of the Workshops will be to define the optimum series of Tasks, their connections, sequence, and dependencies that will ultimately reflect a business process that meets the needs of the business. Now let’s take another scenario. Assume you are working on a Content Management project that involves automating the creation and management of content for User Manuals, Web Sites, Social Media publications etc. Would you call this type of project “Process Centric”?.......well you could, but it might also fall into the category of complex configuration, plus some custom extensions to a standard software application (COTS). For this type of project it would certainly be worth considering using a Use Case approach in order to 1) understand the requirements, and 2) to capture the functional requirements of the custom extensions. At this point you might be asking “why couldn’t I use a Process Modeling approach for my Content Management project?” Well, of course you could, but you just need to think about which approach is the most effective. Start by analyzing the types of Tasks that will eventually be automated by the system, for example: Best Suited To? Task Name Process Model Use Case Notes Manage outbound calls Ö A series of linked human and system tasks for calling and following up with prospects Manage content revision Ö Updating the content on a website Update User Preferences Ö Updating a users display preferences Assign Lead Ö Reviewing a lead, then assigning it to a sales person Convert Lead to Quote Ö Updating the status of a lead, and then converting it to a sales order As you can see, it’s not an exact science, and either approach is viable for the Tasks listed above. However, where you have a series of interconnected Tasks or Activities, than when combined, deliver value to the business, then that would be a good indicator to lead with a Process Modeling approach. On the other hand, when the Tasks or Activities in question are more isolated and/or do not cross traditional departmental boundaries, then a Use Case approach might be worth considering. Now let’s take one final scenario….. As you captured the To-Be Process flows for the Sales Force automation project, you discover a “Gap” in terms of what the client requires, and what the standard COTS application can provide. Let’s assume that the only way forward is to develop a Custom Extension. This would now be a perfect opportunity to document the functional requirements (behind the Gap) using a Use Case approach. After all, we will be developing some new software, and one of the most effective ways to begin the Software Development Lifecycle is to follow a Use Case approach. As always, your comments are most welcome.

  • Click Once Deployment Process and Issue Resolution

    - by Geordie
    Introduction We are adopting Click Once as a deployment standard for Thick .Net application clients.  The latest version of this tool has matured it to a point where it can be used in an enterprise environment.  This guide will identify how to use Click Once deployment and promote code trough the dev, test and production environments. Why Use Click Once over SCCM If we already use SCCM why add Click Once to the deployment options.  The advantages of Click Once are their ability to update the code in a single location and have the update flow automatically down to the user community.  There have been challenges in the past with getting configuration updates to download but these can now be achieved.  With SCCM you can do the same thing but it then needs to be packages and pushed out to users.  Each time a new user is added to an application, time needs to be spent by an administrator, to push out any required application packages.  With Click Once the user would go to a web link and the application and pre requisites will automatically get installed. New Deployment Steps Overview The deployment in an enterprise environment includes several steps as the solution moves through the development life cycle before being released into production.  To make mitigate risk during the release phase, it is important to ensure the solution is not deployed directly into production from the development tools.  Although this is the easiest path, it can introduce untested code into production and result in unexpected results. 1. Deploy the client application to a development web server using Visual Studio 2008 Click Once deployment tools.  Once potential production versions of the solution are being generated, ensure the production install URL is specified when deploying code from Visual Studio.  (For details see ‘Deploying Click Once Code from Visual Studio’) 2. xCopy the code to the test server.  Run the MageUI tool to update the URLs, signing and version numbers to match the test server. (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) 3. xCopy the code to the production server.  Run the MageUI tool to update the URLs, signing and version numbers to match the production server. The certificate used to sign the code should be provided by a certificate authority that will be trusted by the client machines.  Finally make sure the setup.exe contains the production install URL.  If not redeploy the solution from Visual Studio to the dev environment specifying the production install URL.  Then xcopy the install.exe file from dev to production.  (For details see ‘Moving Click Once Code to a new Server without using Visual Studio’) Detailed Deployment Steps Deploying Click Once Code From Visual Studio Open Visual Studio and create a new WinForms or WPF project.   In the solution explorer right click on the project and select ‘Publish’ in the context menu.   The ‘Publish Wizard’ will start.  Enter the development deployment path.  This could be a local directory or web site.  When first publishing the solution set this to a development web site and Visual basic will create a site with an install.htm page.  Click Next.  Select weather the application will be available both online and offline. Then click Finish. Once the initial deployment is completed, republish the solution this time mapping to the directory that holds the code that was just published.  This time the Publish Wizard contains and additional option.   The setup.exe file that is created has the install URL hardcoded in it.  It is this screen that allows you to specify the URL to use.  At some point a setup.exe file must be generated for production.  Enter the production URL and deploy the solution to the dev folder.  This file can then be saved for latter use in deployment to production.  During development this URL should be pointing to development site to avoid accidently installing the production application. Visual studio will publish the application to the desired location in the process it will create an anonymous ‘pfx’ certificate to sign the deployment configuration files.  A production certificate should be acquired in preparation for deployment to production.   Directory structure created by Visual Studio     Application files created by Visual Studio   Development web site (install.htm) created by Visual Studio Migrating Click Once Code to a new Server without using Visual Studio To migrate the Click Once application code to a new server, a tool called MageUI is needed to modify the .application and .manifest files.  The MageUI tool is usually located – ‘C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin’ folder or can be downloaded from the web. When deploying to a new environment copy all files in the project folder to the new server.  In this case the ‘ClickOnceSample’ folder and contents.  The old application versions can be deleted, in this case ‘ClickOnceSample_1_0_0_0’ and ‘ClickOnceSample_1_0_0_1’.  Open IIS Manager and create a virtual directory that points to the project folder.  Also make the publish.htm the default web page.   Run the ManeUI tool and then open the .application file in the root project folder (in this case in the ‘ClickOnceSample’ folder). Click on the Deployment Options in the left hand list and update the URL to the new server URL and save the changes.   When MageUI tries to save the file it will prompt for the file to be signed.   This step cannot be bypassed if you want the Click Once deployment to work from a web site.  The easiest solution to this for test is to use the auto generated certificate that Visual Studio created for the project.  This certificate can be found with the project source code.   To save time go to File>Preferences and configure the ‘Use default signing certificate’ fields.   Future deployments will only require application files to be transferred to the new server.  The only difference is then updating the .application file the ‘Version’ must be updated to match the new version and the ‘Application Reference’ has to be update to point to the new .manifest file.     Updating the Configuration File of a Click Once Deployment Package without using Visual Studio When an update to the configuration file is required, modifying the ClickOnceSample.exe.config.deploy file will not result in current users getting the new configurations.  We do not want to go back to Visual Studio and generate a new version as this might introduce unexpected code changes.  A new version of the application can be created by copying the folder (in this case ClickOnceSample_1_0_0_2) and pasting it into the application Files directory.  Rename the directory ‘ClickOnceSample_1_0_0_3’.  In the new folder open the configuration file in notepad and make the configuration changes. Run MageUI and open the manifest file in the newly copied directory (ClickOnceSample_1_0_0_3).   Edit the manifest version to reflect the newly copied files (in this case 1.0.0.3).  Then save the file.  Open the .application file in the root folder.  Again update the version to 1.0.0.3.  Since the file has not changed the Deployment Options/Start Location URL should still be correct.  The application Reference needs to be updated to point to the new versions .manifest file.  Save the file. Next time a user runs the application the new version of the configuration file will be down loaded.  It is worth noting that there are 2 different types of configuration parameter; application and user.  With Click Once deployment the difference is significant.  When an application is downloaded the configuration file is also brought down to the client machine.  The developer may have written code to update the user parameters in the application.  As a result each time a new version of the application is down loaded the user parameters are at risk of being overwritten.  With Click Once deployment the system knows if the user parameters are still the default values.  If they are they will be overwritten with the new default values in the configuration file.  If they have been updated by the user, they will not be overwritten. Settings configuration view in Visual Studio Production Deployment When deploying the code to production it is prudent to disable the development and test deployment sites.  This will allow errors such as incorrect URL to be quickly identified in the initial testing after deployment.  If the sites are active there is no way to know if the application was downloaded from the production deployment and not redirected to test or dev.   Troubleshooting Clicking the install button on the install.htm page fails. Error: URLDownloadToCacheFile failed with HRESULT '-2146697210' Error: An error occurred trying to download <file>   This is due to the setup.exe file pointing to the wrong location. ‘The setup.exe file that is created has the install URL hardcoded in it.  It is this screen that allows you to specify the URL to use.  At some point a setup.exe file must be generated for production.  Enter the production URL and deploy the solution to the dev folder.  This file can then be saved for latter use in deployment to production.  During development this URL should be pointing to development site to avoid accidently installing the production application.’

  • Calling oracle stored procedure from Excel - VBA

    - by Ram
    I have to execute an Oracle stored procedure from vba (Excel) with around 38 input parameters. The stored procedure will insert some values in the destination table once that is executed. When it is executed through VBA the number of fields which is inserted is less than when it is executed directly from the backend (oracle). For example it is creating around 17 fields of records while executing directly from the back end. (I have created a wrapper class in the back-end and passing the same parameter values in the back-end.). It is creating around 15 fields of records while executing from the excel VBA in the destination table. Kindly let me know what could be the possible reasons for this.

  • Subsonic 3 fails to identify Stored Procedure Output Parameter

    - by CmdrTallen
    Hi using Subsonic 3.0.0.3 it appears there is some issue with Subsonic identifying Stored Procedure paramters as output parameters. In the StoredProcedures.cs class I find my stored procedure definition but the last parameter is defined incorrectly as a 'AddParameter'. sp.Command.AddParameter("HasPermission",HasPermission,DbType.Boolean); When I sp.Execute() and attempt to read the value of the sp.Command.OutputValues[0] the value is null. If the definition is edited to be like this; sp.Command.AddOutputParameter("HasPermission", DbType.Boolean); Then the value is returned and is correct value type I am not sure how I 'fix' this - as everytime I regen the SP class via the 'Run Custom Tool' the parameter definitions require editing. Should I edit a T4 template somehow? Please advise. EDIT: I forgot to mention I am using MS SQL 2008 (10.0.2531)

  • Generating a text file in MYSQL stored procedure

    - by Pablo
    Hi, I'm new to MySQL, I am trying to create a text file using a stored procedure. I'm currently at the stage where I have a temporary table that contains all of the records that I want to output to a text file. I have the following line at the end of my SP, it works in PHPMYAdmin's query but it does not work when part of a stored procedure the code is as follows: SELECT * into outfile '../../htdocs/VIP/Temp/temp.txt' from tmp_Menu2; note that tmp_Menu2 is a table that only includes one field of type VARCHAR(1000) Any help would be greathly appreciated. Thank you,

  • Visual Studio - "attach to particular instance of the process" macro

    - by Steve
    I guess prety much everyone who does a lot of debugging have a handy macro in Visual Studio (with shortcut to it on a toolbar) which when called automatically attaches to a particular process (identified by name). it saves a lot of time rather than clicking "Debug" - "Attach to the process ...", but it only works if one is running a single instance of the process one wants to attach to. If theres is more than one instance of particular process in memory - the first one (with a smaller PID?) is being choose by debugger. Does anyone have a macro which shows a dialog (if more that 1 process with a specified name running) and lets developer to select to one he/she really wants to attach to. I guess the selection could be made based on a windwow caption text (which would be suffice in most of cases) and when the particular instance is selected macro passes the PID of the process to the Debugger object? If someone has that macro or knows how to write it - please share. Thanks.

  • Finding the stored procedure that a Crystal Report is using

    - by Brandon
    I need to retrieve the name of the stored procedure that a crystal report is running. Is there any way to do this in C# using the CrystalDecisions.CrystalReports.Engine.ReportDocument object? I can't seem to find a property that will give me the stored procedure name. Is this even possible? I've been through almost all the properties I can think of. The DataDefinition object has collections for the Formula, Parameter, Group Name, and Running Total Fields, but not one for the Database Fields.

  • One project in Delphi 2007 doesn't show procedure name in the IDE Obj Inspector's Events

    - by lgallion
    I have a Delphi project in 2007 that doesn't show the procedure names in the Object Inspector's Events such as Form OnClose, OnCreate or OnShow in the IDE. The code is there and if you click on OnCreate (for example) you are taken to the code and the IDE fills in the name of procedure. However on reload, the procedures are missing from the IDE again. This same project causes various error messages when Delphi closes also, but I am not sure if this is related (no other project developed under this Delphi does but this one is the largest app and uses several 3rd party add-in libraries). I have moved this app to various Delphi 2007 installations and it reacts the same, so it isn't a corrupt Delphi situation. Is there any way to rebuild or fix a corrupt project like this? Any help would be appreciated.

  • System.Diaganostics.Process.Id Isn't the Same Process Id Shown in Task Manger. Why?

    - by LonnieBest
    I'm using c#'s System.Diagnostic.Process object. One of its properties is Id. The Id this produces is not the same as the PID, shown in Windows Task Manager. Why is this? You see, once this process is started. It launches two other unmanaged processes, for which I can't explicitly get IDs for by object property references. I have to search through all processes to find them by process name via System.Diagnostics.Process.GetProcesses(). I'm trying to find a reliable way to kill this process and all associated processes by PID, the one that shows in Task Manager. Is there a better way? I can't just kill all processes with the associated process names, because that might kill other instances of those processes that have nothing to do with my program.

  • switch between two cursors based on parameter passed into stored procedure

    - by db83
    Hi, I have two cursors in my procedure that only differ on the table name that they join to. The cursor that is used is determined by a parameter passed into the procedure if (param = 'A') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table2 b BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; elsif (param = 'B') then DECLARE CURSOR myCursor IS SELECT x,y,z FROM table1 a, table3 b -- different table BEGIN FOR aRecord in myCursor LOOP proc2(aRecord.x, aRecord.y, aRecord.z); END LOOP; COMMIT; END; end if I don't want to repeat the code for the sake of one different table. Any suggestions on how to improve this? Thanks in advance

  • Procedure or function expects parameter which was not supplied

    - by eftpotrm
    Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.) C#: SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn); l_oCmd.Parameters.Add(new SqlParameter("@test", SqlDbType.NVarChar)); l_oCmd.Parameters[0].Value = "hello world"; SqlDataAdapter da = new SqlDataAdapter(l_oCmd); da.Fill(l_oPage); SQL: create procedure usp_test ( @test nvarchar(1000) ) as select @test What have I missed?

  • Java framework "suggestion" for persisting the results from an Oracle 9i stored procedure using Apac

    - by chocksaway
    Hello, I am developing a Java servlet which calls an Oracle stored procedure. The stored procedure is likely to "grow" over time, and I have concerns the amount of time taken to "display the results on a web page". While I am at the implementation stage, I would like some suggestions of a Persistence framework which will work on Apache Tomcat 5.5? I see two approaches to persisting the database results. A scheduled database query every N minutes, or something which utilises triggers. Hibernate seems like the obvious answer, but I have never called stored procedures from Hibernate (HQL and Criteria). Is there a more appropriate framework which can be used? Thank you. cheers Miles.
