• What Is The Best Database For Delphi Desktop Applications That Supports Stored Procedures?

  - by Cape Cod Gunny

  I started with Turbo Pascal 3, went to TP5, Bought TP6 called Borland the next day and downgraded to TP5.5. Bought Delphi 3, and now have Delphi 5 Enterprise. I sort of lost interest in writing code about 4-5 years ago for two reasons; Spent all day writing ASP & SQL for someone else. PC Techniques magazine went away. I've got a few programs in the shareware market that are solid performers but are in need of serious updating. I love Delphi or did when it was Borland (before Borland bought DBase and all the other crap), I'd like to salvage as much of my D5E code as possible but I doubt I can. I plan on upgrading to Delphi 2010. My next software release needs to interact with a database. I'm very proficient with MS Sql and like to put all of the database code in stored procedures. What is the best database choice that interacts well with Delphi, allows stored procedures and is so easy to deploy that even the Geico gecko could deploy it? 10/25/2009 18:53 PM EST Re-Opened After Reading Install Docs for Delphi 2010 I downloaded a trial version of Delphi 2010 and unzipped the install. I've been reading the install docs included in the package. I started with the install.htm inside the zip package. install.htm wisely tells you to see the following two articles: Installation Notes: http://edn.embarcadero.com/article/39754 Release Notes: http://edn.embarcadero.com/article/39758 the release notes state the following... MSSQL driver requires the installation of the SQL Native Client. SQL Native Client 2008 is required for dbxmss.dll. SQL Native Client 2005 is required for dbxmss9.dll I checked my machine to see if SQL Native Client is installed. Nope. I wasn't done reading the docs so I made a note to install SQL Native Client. I googled dbxmss.dll and dbxmss9.dll and found a very interesting thread on the Embarcadero forums. read thread here. After reading this thread and some careful thought I don't think I will be using Microsoft SQL Express. I can't rely on my customers having the right drivers installed. So, I'm back to looking for a different solution. If I'm selling a $40 product to the general masses I need to have a bulletproof solution that doesn't require my brand new customer to update their machine before my software will work.

• Path for Delphi libraries

  - by Wouter van Nifterick

  Where do you guys store 3rd party (and your own) components? Do you keep separate copies per Delphi version? For years I've been using c:\program files\borland\delphi7\lib\, even for Delphi 2006, 2007, 2009 and 2010, like this: c:\program files\borland\delphi7\lib\AggPas\ c:\program files\borland\delphi7\lib\DeHL\ c:\program files\borland\delphi7\lib\DevExpress\ c:\program files\borland\delphi7\lib\FastCode\ c:\program files\borland\delphi7\lib\FastMM\ c:\program files\borland\delphi7\lib\Fundamentals\ c:\program files\borland\delphi7\lib\Graphics32\ c:\program files\borland\delphi7\lib\JCL\ c:\program files\borland\delphi7\lib\JVCL\ c:\program files\borland\delphi7\lib\OmniThread\ c:\program files\borland\delphi7\lib\Raize\ c:\program files\borland\delphi7\lib\TeeChartPro\ c:\program files\borland\delphi7\lib\TurboPower\ c:\program files\borland\delphi7\lib\VirtualTreeView\ c:\program files\borland\delphi7\lib\Zeos\ However, nowadays I don't even use Delphi7 anymore (what can it do that 2010 can't?), so this path doesn't make much sense anymore. I'm about to install windows7 on my home machine, so I'm thinking on something like this: c:\src\DelphiLib\ Any better ideas?

• SQL SERVER – Tricks to Replace SELECT * with Column Names – SQL in Sixty Seconds #017 – Video

  - by pinaldave

  You might have heard many times that one should not use SELECT * as there are many disadvantages to the usage of the SELECT *. I also believe that there are always rare occasion when we need every single column of the query. In most of the cases, we only need a few columns of the query and we should retrieve only those columns. SELECT * has many disadvantages. Let me list a few and remaining you can add as a comment.  Retrieves unnecessary columns and increases network traffic When a new columns are added views needs to be refreshed manually Leads to usage of sub-optimal execution plan Uses clustered index in most of the cases instead of using optimal index It is difficult to debug. There are two quick tricks I have discussed in the video which explains how users can avoid using SELECT * but instead list the column names. 1) Drag the columns folder from SQL Server Management Studio to Query Editor 2) Right Click on Table Name >> Script TAble AS >> SELECT To… >> Select option It is extremely easy to list the column names in the table. In today’s sixty seconds video, you will notice that I was able to demonstrate both the methods very quickly. From now onwards there should be no excuse for not listing ColumnName. Let me ask a question back – is there ever a reason to SELECT *? If yes, would you please share that as a comment. More on SELECT *: SQL SERVER – Solution – Puzzle – SELECT * vs SELECT COUNT(*) SQL SERVER – Puzzle – SELECT * vs SELECT COUNT(*) SQL SERVER – SELECT vs. SET Performance Comparison I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can. If we like your idea we promise to share with you educational material.

• Removing non-alphanumeric characters in an Access Field.

  - by Jacques Tardie

  I need to remove hyphens from a string in a large number of access fields. What's the best way to go about doing this? Currently, the entries are follow this general format: 2010-54-1 2010-56-1 etc. I'm trying to run append queries off of this field, but I'm always getting validation errors causing the query to fail. I think the cause of this failure is the hypens in the entries, which is why I need to remove them. I've googled, and I see that there are a number of formatting guides using vbscript, but I'm not sure how I can integrate vb into Access. It's new to me :) Thanks in advance, Jacques

• Why does setting a geometry shader cause my sprites to vanish?

  - by ChaosDev

  My application has multiple screens with different tasks. Once I set a geometry shader to the device context for my custom terrain, it works and I get the desired results. But then when I get back to the main menu, all sprites and text disappear. These sprites don't dissappear when I use pixel and vertex shaders. The sprites are being drawn through D3D11, of course, with specified view and projection matrices as well an input layout, vertex, and pixel shader. I'm trying DeviceContext->ClearState() but it does not help. Any ideas? void gGeometry::DrawIndexedWithCustomEffect(gVertexShader*vs,gPixelShader* ps,gGeometryShader* gs=nullptr) { unsigned int offset = 0; auto context = mp_D3D->mp_Context; //set topology context->IASetPrimitiveTopology(m_Topology); //set input layout context->IASetInputLayout(mp_inputLayout); //set vertex and index buffers context->IASetVertexBuffers(0,1,&mp_VertexBuffer->mp_Buffer,&m_VertexStride,&offset); context->IASetIndexBuffer(mp_IndexBuffer->mp_Buffer,mp_IndexBuffer->m_DXGIFormat,0); //send constant buffers to shaders context->VSSetConstantBuffers(0,vs->m_CBufferCount,vs->m_CRawBuffers.data()); context->PSSetConstantBuffers(0,ps->m_CBufferCount,ps->m_CRawBuffers.data()); if(gs!=nullptr) { context->GSSetConstantBuffers(0,gs->m_CBufferCount,gs->m_CRawBuffers.data()); context->GSSetShader(gs->mp_D3DGeomShader,0,0);//after this call all sprites disappear } //set shaders context->VSSetShader( vs->mp_D3DVertexShader, 0, 0 ); context->PSSetShader( ps->mp_D3DPixelShader, 0, 0 ); //draw context->DrawIndexed(m_indexCount,0,0); } //sprites void gSpriteDrawer::Draw(gTexture2D* texture,const RECT& dest,const RECT& source, const Matrix& spriteMatrix,const float& rotation,Vector2d& position,const Vector2d& origin,const Color& color) { VertexPositionColorTexture* verticesPtr; D3D11_MAPPED_SUBRESOURCE mappedResource; unsigned int TriangleVertexStride = sizeof(VertexPositionColorTexture); unsigned int offset = 0; float halfWidth = ( float )dest.right / 2.0f; float halfHeight = ( float )dest.bottom / 2.0f; float z = 0.1f; int w = texture->Width(); int h = texture->Height(); float tu = (float)source.right/(w); float tv = (float)source.bottom/(h); float hu = (float)source.left/(w); float hv = (float)source.top/(h); Vector2d t0 = Vector2d( hu+tu, hv); Vector2d t1 = Vector2d( hu+tu, hv+tv); Vector2d t2 = Vector2d( hu, hv+tv); Vector2d t3 = Vector2d( hu, hv+tv); Vector2d t4 = Vector2d( hu, hv); Vector2d t5 = Vector2d( hu+tu, hv); float ex=(dest.right/2)+(origin.x); float ey=(dest.bottom/2)+(origin.y); Vector4d v4Color = Vector4d(color.r,color.g,color.b,color.a); VertexPositionColorTexture vertices[] = { { Vector3d( dest.right-ex, -ey, z),v4Color, t0}, { Vector3d( dest.right-ex, dest.bottom-ey , z),v4Color, t1}, { Vector3d( -ex, dest.bottom-ey , z),v4Color, t2}, { Vector3d( -ex, dest.bottom-ey , z),v4Color, t3}, { Vector3d( -ex, -ey , z),v4Color, t4}, { Vector3d( dest.right-ex, -ey , z),v4Color, t5}, }; auto mp_context = mp_D3D->mp_Context; // Lock the vertex buffer so it can be written to. mp_context->Map(mp_vertexBuffer, 0, D3D11_MAP_WRITE_DISCARD, 0, &mappedResource); // Get a pointer to the data in the vertex buffer. verticesPtr = (VertexPositionColorTexture*)mappedResource.pData; // Copy the data into the vertex buffer. memcpy(verticesPtr, (void*)vertices, (sizeof(VertexPositionColorTexture) * 6)); // Unlock the vertex buffer. mp_context->Unmap(mp_vertexBuffer, 0); //set vertex shader mp_context->IASetVertexBuffers( 0, 1, &mp_vertexBuffer, &TriangleVertexStride, &offset); //set texture mp_context->PSSetShaderResources( 0, 1, &texture->mp_SRV); //set matrix to shader mp_context->UpdateSubresource(mp_matrixBuffer, 0, 0, &spriteMatrix, 0, 0 ); mp_context->VSSetConstantBuffers( 0, 1, &mp_matrixBuffer); //draw sprite mp_context->Draw( 6, 0 ); }

• Rails AtomFeedBuilder Entry :Url option appears in url tag but not in link tag

  - by Nick

  Hello, I'm using the AtomFeedHelper and everything is working fine except for one feed where I need to link each entry to a URL which is not the default polymorphic_url for the record. Per the documentation I've specified an :url option for the entry. This correctly renders a <url> tag in the atom node but the <link rel="alternate" still points to the default polymorphic_url. Looking at the source and the documentation I don't understand why this is happening. Here's an example builder: atom_feed do |feed| feed.title("Reports") feed.updated(@reports.first.created_at) for report in @reports content = report.notes feed.entry(report) do |entry| entry.title(report.title) entry.content(content, :type => 'html') entry.url("http://myhost/page/") entry.updated(report.updated_at.strftime("%Y-%m-%dT%H:%M:%SZ")) entry.author do |author| author.name(report.user.username) end end end end Here's an example of a problem node: <entry> <id>tag:molly.recargo.com,2005:SiteReport/2</id> <published>2010-03-30T13:11:07-07:00</published> <updated>2010-03-30T13:11:07-07:00</updated> <link rel="alternate" type="text/html" href="http://myhost/site_reports/2"/> <title>Test Title</title> <content type="html">Test Content</content> <url>http://myhost/page/</url> <updated>2010-03-30T13:11:07Z</updated> <author> <name>Author</name> </author> </entry> I wan the href value in the link tag to match the value in the url tag but it does not. When I look at the source listed for entry here http://api.rubyonrails.org/classes/ActionView/Helpers/AtomFeedHelper/AtomFeedBuilder.html I'd assume that this line would work correctly: @xml.link(:rel => 'alternate', :type => 'text/html', :href => options[:url] || @view.polymorphic_url(record)) Confused. Has anyone encountered this before? Thanks all!

• CLR via C# 3rd Edition is out

  - by Abhijeet Patel

  Time for some book news update. CLR via C#, 3rd Edition seems to have been out for a little while now. The book was released in early Feb this year, and needless to say my copy is on it’s way. I can barely wait to dig in and chew on the goodies that one of the best technical authors and software professionals I respect has in store. The 2nd edition of the book was an absolute treat and this edition promises to be no less. Here is a brief description of what’s new and updated from the 2nd edition. Part I – CLR Basics Chapter 1-The CLR’s Execution Model Added about discussion about C#’s /optimize and /debug switches and how they relate to each other. Chapter 2-Building, Packaging, Deploying, and Administering Applications and Types Improved discussion about Win32 manifest information and version resource information. Chapter 3-Shared Assemblies and Strongly Named Assemblies Added discussion of TypeForwardedToAttribute and TypeForwardedFromAttribute. Part II – Designing Types Chapter 4-Type Fundamentals No new topics. Chapter 5-Primitive, Reference, and Value Types Enhanced discussion of checked and unchecked code and added discussion of new BigInteger type. Also added discussion of C# 4.0’s dynamic primitive type. Chapter 6-Type and Member Basics No new topics. Chapter 7-Constants and Fields No new topics. Chapter 8-Methods Added discussion of extension methods and partial methods. Chapter 9-Parameters Added discussion of optional/named parameters and implicitly-typed local variables. Chapter 10-Properties Added discussion of automatically-implemented properties, properties and the Visual Studio debugger, object and collection initializers, anonymous types, the System.Tuple type and the ExpandoObject type. Chapter 11-Events Added discussion of events and thread-safety as well as showing a cool extension method to simplify the raising of an event. Chapter 12-Generics Added discussion of delegate and interface generic type argument variance. Chapter 13-Interfaces No new topics. Part III – Essential Types Chapter 14-Chars, Strings, and Working with Text No new topics. Chapter 15-Enums Added coverage of new Enum and Type methods to access enumerated type instances. Chapter 16-Arrays Added new section on initializing array elements. Chapter 17-Delegates Added discussion of using generic delegates to avoid defining new delegate types. Also added discussion of lambda expressions. Chapter 18-Attributes No new topics. Chapter 19-Nullable Value Types Added discussion on performance. Part IV – CLR Facilities Chapter 20-Exception Handling and State Management This chapter has been completely rewritten. It is now about exception handling and state management. It includes discussions of code contracts and constrained execution regions (CERs). It also includes a new section on trade-offs between writing productive code and reliable code. Chapter 21-Automatic Memory Management Added discussion of C#’s fixed state and how it works to pin objects in the heap. Rewrote the code for weak delegates so you can use them with any class that exposes an event (the class doesn’t have to support weak delegates itself). Added discussion on the new ConditionalWeakTable class, GC Collection modes, Full GC notifications, garbage collection modes and latency modes. I also include a new sample showing how your application can receive notifications whenever Generation 0 or 2 collections occur. Chapter 22-CLR Hosting and AppDomains Added discussion of side-by-side support allowing multiple CLRs to be loaded in a single process. Added section on the performance of using MarshalByRefObject-derived types. Substantially rewrote the section on cross-AppDomain communication. Added section on AppDomain Monitoring and first chance exception notifications. Updated the section on the AppDomainManager class. Chapter 23-Assembly Loading and Reflection Added section on how to deploy a single file with dependent assemblies embedded inside it. Added section comparing reflection invoke vs bind/invoke vs bind/create delegate/invoke vs C#’s dynamic type. Chapter 24-Runtime Serialization This is a whole new chapter that was not in the 2nd Edition. Part V – Threading Chapter 25-Threading Basics Whole new chapter motivating why Windows supports threads, thread overhead, CPU trends, NUMA Architectures, the relationship between CLR threads and Windows threads, the Thread class, reasons to use threads, thread scheduling and priorities, foreground thread vs background threads.

• NULL value when using NSDateFormatter

  - by David A Gibson

  Hello, I am using the following code to try and display in a time in a table cell. TimeSlot *timeSlot = [timeSlots objectAtIndex:indexPath.row]; NSDateFormatter *timeFormat = [[NSDateFormatter alloc] init]; [timeFormat setDateFormat:@"%1m/%1d/%Y"]; NSLog(@"Time: %@", timeSlot.time); NSDate *mydate = timeSlot.time; NSLog(@"Time: %@", mydate); NSString *theTime = [timeFormat stringFromDate:mydate]; NSLog(@"Time: %@", theTime); The log output is this: 2010-04-14 10:23:54.626 MyApp[1080:207] Time: 2010-04-14T10:23:54 2010-04-14 10:23:54.627 MyApp[1080:207] Time: 2010-04-14T10:23:54 2010-04-14 10:23:54.627 MyApp[1080:207] Time: (null) I am new to developing for the iPhone and as it all compiles with no errors or warnings I am at a loss as to why I am getting NULL in the log. Is there anything wrong with this code? Thanks

• Problem with Google App Engine Appstats

  - by Taylor L

  I'm having an issue getting Appstats to work correctly. Using /appstats or /appstats/stats ends up in an infinite loop that keeps redirecting back to /appstats/stats. This results in a 404 error saying the page isn't redirecting properly. Any idea what the issue is? Here are the relevant lines in my appengine-web.xml. I've tried using both /appstats/stats and /appstats and they both have the same issue. <admin-console> <page name="Appstats" url="/appstats/stats" /> </admin-console> Below are the http headers showing the infinite redirect loop: http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcHiwT8jH7e01V9O5iFu3kpBhDd3k3oBwwxylv5u0DbJ- utvdpsgdb4Xim2WXwobkJmgTGGljvuh94_yVQ__- VPnBsTtUAhRjSyZ2Lv3G7oUHAxTsCWHJIMChGT3- XUyUNx8wxwvJisL_RTXH8Hc4TTLh_rVHm2k8gk8kgdbVZXexSV0K- a3coELTecWIBolt0qLd5L-5vALm382KsqbHorPXqoZMPTvR_06g_mR1cbmF2Ihnk6YhP7no58BNpESM9HvFyKNKXODo39hF4oaZCcW0Q9TBqUMgsrBqlcIh3- VvC7qvH0n_nAtrLTBbK_swnOFvCDcaf3whT9ty0CJ0VRNuNqIPOLHIeQAMgwXUNMr89P64EsgmuyONHR67glCQXEPOGXIaT1vcBJFwFoeNUqjdp824fHvoVhaL7Xlav- LTIFuM3f_ymHLmibk57PRuXUYEaAG HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.645553 X-AppEngine-Resource-Usage: ms=18965 cpu_ms=27884 api_cpu_ms=0 Set-Cookie: ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS; expires=Mon, 12-Apr-2010 19:41:49 GMT; path=/ Date: Sun, 11 Apr 2010 19:42:08 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, must-revalidate Content-Type: text/html Server: Google Frontend Content-Length: 0 ---------------------------------------------------------- http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.002243 X-AppEngine-Resource-Usage: ms=64 cpu_ms=93 api_cpu_ms=0 Date: Sun, 11 Apr 2010 19:42:08 GMT Content-Type: text/html Server: Google Frontend Content-Length: 0

• Accessing TFS from Powershell

  - by w4ymo

  Hello I am new to PowerShell and I am trying to get branches from TFS and merge them using a PowerShell script. Unfortunately I am failing a first hurdle. I do have Visual Studio 2010 install on my local machine and can access the TFS server (also 2010) fine. I am running the script from my local machine and have the following lines: $tfs = get-tfs http://TFSServerName:8080/TFSProject $branchfolders = $tfs.VCS.GetItems('$/Dev/Branches/', $tfs.RecursionType::OneLevel) and I receive the following error on the second line 2 above Exception calling "GetItems" with "2" argument(s): "Unable to connect to the remote server" I have configured the TFS server to accept incoming connections on port 8080 which works but I am now not to sure how to resolve this error. Is further configuration required? Thanks for any help given.

• Formatting the date in unix to include suffix on day (st, nd, rd and th)

  - by skymook

  How can I add the suffix on the day number of a unix date? I'll explain. I have a TextMate bundle snippit that writes out today's date. It uses unix date and formatting. Here is the code: `date +%A` `date +%d` `date +%B` `date +%Y` It outputs: Monday 22 March 2010 I would like to add the suffix to the day (st, nd, rd and th) like so: Monday 22nd March 2010 As far as I can see, there is no native function in the unix date formatting, like there is in PHP (j). How would I achieve this in unix? A complicated regex on the day number?

• Does Javascript/EcmaScript3 support ISO8601 date parsing?

  - by AlexanderN

  How are you currently parsing ISO8601 dates e.g. 2010-02-23T23:04:48Z in JavaScript? Some browsers return NaN (including Chrome) when using the code below, FF3.6+ works though. <html> <body> <script type="text/javascript"> var d = Date.parse("2010-02-23T23:04:48Z"); document.write(d); </script> </body> </html> You can try this here http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_parse ps: DateJs doesn't seem to support ISO8601 parsing.

• WPF MVVM Pattern, ViewModel DataContext question

  - by orangecl4now

  I used this side to create my demo application http://windowsclient.net/learn/video.aspx?v=314683 The site was very useful in getting my started and in their example, they created a file called EmployeeRepository.cs which appears to be the source for the data. In their example, the data was hard-wired in code. So I'm trying to learn how to get the data from a data source (like a DB). In my specific case, I want to get the data from a Microsoft Access DB. (READ ONLY, So I'll only use SELECT commands). using System.Collections.Generic; using Telephone_Directory_2010.Model; namespace Telephone_Directory_2010.DataAccess { public class EmployeeRepository { readonly List<Employee> _employees; public EmployeeRepository() { if (_employees == null) { _employees = new List<Employee>(); } _employees.Add(Employee.CreateEmployee("Student One", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); _employees.Add(Employee.CreateEmployee("Student Two", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); _employees.Add(Employee.CreateEmployee("Student Three", "IT201", "Information Technology", "IT4207", "Building1", "Room650")); } public List<Employee> GetEmployees() { return new List<Employee>(_employees); } } } I found another example where an Access DB is used but it doesn't comply with MVVM. So I was trying to figure out how to add the DB file to the project, how to wire it up and bind it to a listbox (i'm not that far yet). Below is my modified file using System.Collections.Generic; using Telephone_Directory_2010.Model; // integrating new code with working code using Telephone_Directory_2010.telephone2010DataSetTableAdapters; using System.Windows.Data; namespace Telephone_Directory_2010.DataAccess { public class EmployeeRepository { readonly List<Employee> _employees; // start // integrating new code with working code private telephone2010DataSet.telephone2010DataTable employeeTable; private CollectionView dataView; internal CollectionView DataView { get { if (dataView == null) { dataView = (CollectionView) CollectionViewSource.GetDefaultView(this.DataContext); } return dataView; } } public EmployeeRepository() { if (_employees == null) { _employees = new List<Employee>(); } telephone2010TableAdapter employeeTableAdapter = new telephone2010TableAdapter(); employeeTable = employeeTableAdapter.GetData(); this.DataContext = employeeTable; } public List<Employee> GetEmployees() { return new List<Employee>(_employees); } } } I get the following error messages when building Error 1 'Telephone_Directory_2010.DataAccess.EmployeeRepository' does not contain a definition for 'DataContext' and no extension method 'DataContext' accepting a first argument of type 'Telephone_Directory_2010.DataAccess.EmployeeRepository' could be found (are you missing a using directive or an assembly reference?)

• Why can't I install MVC (1 or 2) with Visual Web Developer Express 2008 RC1?

  - by Stefan

  Hi all, I have installed VWD 2010 Express and love MVC2. I have an existing ASP.NET 3.5 website that I'd like to redevelop with ASP.NET MVC2 under VWD 2008 with the 3.5 framework (the host only supports .Net 3.5, and Express 2010 doesn't support targeting of .Net framework versions) I am however unable to install MVC2 with VWD 2008. The installer (for 2008 SP1) says it has installed, but the MVC project templates don't show up when I create a new project. I also had this problem originally with MVC1 which is why I gave up at some point and just created it as a normal ASP.NET website. I tried uninstalling and installing VWD 2008, and then installing MVC2, but this didn't solve the problem. Does anyone know why this problem occurs, or how to solve it? Or is there a way to add these templates and the tooling manually?

• Using IIRF to redirect to a PDF

  - by Michael Itzoe

  I'm using IIRF to redirect certain URLs to specific PDF files. For instance, for the URL /newsletter/2010/02 I'd like it to redirect to /pdf/newsletters/Feb2010.pdf. I'm not too hot at regular expressions, but I created the following rule: RedirectRule ^/newsletter/2010/01 /pdf/newsletters/Newsletter012010.pdf [I,R=301] and it does redirect, but the address bar doesn't change, and when trying to save the file it wants to save as 01 instead of Feb2010.pdf. I don't presume my users will be savvy enough to enter a PDF extension before saving, and they shouldn't have to. Is there anything I can do about this?

• How does the Twitter rate limit API work with multiple accounts?

  - by dfrankow

  I know there's a Rest API to check the Twitter rate limit. To summarize policy: 150 for an IP, and 150 per non-whitelisted account except for searches (which are IP only). However, my app is using Twython, authenticated, but the limit seems to decrease for both my accounts as I use it. Example: No authentication: $ wget http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <hourly-limit type="integer">150</hourly-limit> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> </hash> Authentication with account #1: $ wget --user b... --password=youwish http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> <hourly-limit type="integer">150</hourly-limit> </hash> Authentication with account #2: $ wget --user d... --password=youwish http://api.twitter.com/1/account/rate_limit_status.xml -O - <?xml version="1.0" encoding="UTF-8"?> <hash> <reset-time type="datetime">2010-02-23T23:49:21+00:00</reset-time> <remaining-hits type="integer">134</remaining-hits> <hourly-limit type="integer">150</hourly-limit> <reset-time-in-seconds type="integer">1266968961</reset-time-in-seconds> </hash> You see how both accounts seem to have exactly the same rate limit info (134/150)? I only used one account in my app, so why do both accounts show decrease?

• How does .NET determine the week in a TimeZoneInfo.TransitionTime ?

  - by Travis Brooks

  Greetings I'm trying to do some DateTime math for various time zones and I wanted to take daylight savings into account. Lets say I have a TimeZoneInfo and i've determined the appropriate AdjustmentRule for a given DateTime. Lets also say the particular TimeZoneInfo i'm dealing with is specified as rule.DaylightTransitionStart.IsFixedDateRule == false, so I need to figure out if the given DateTime falls within the start/end TransitionTime.Week values. This is where I'm getting confused, what is .NET considering as a "week"? My first thought was it probably used something like DayOfWeek thisMarksWeekBoundaries = Thread.CurrentThread.CurrentUICulture.DateTimeFormat.FirstDayOfWeek; and went through the calendar assigning days to week, incrementing week every time it crossed a boundary. But, if I do this for May 2010 there are 6 week boundary buckets, and the max valid value for TransitionTime.Week is 5 so this can't be right. Whats the right way to slice up May 2010?

• Creating an XML sitemap with PHP

  - by iMaster

  I'm trying to create a sitemap that will automatically update. I've done something similiar with my RSS feed, but this sitemap refuses to work. You can view it live at http://designdeluge.com/sitemap.xml I think the main problem is that its not recognizing the PHP code.

• How to get image capture date and video duration when uploading files using SWFUpload and Paperclip

  - by Hatem

  Hi Guys, I'm using SWFUpload and Paperclip on Rails 2.3.5 to upload images and videos. How can I store the capture date of images and duration of videos? The following works correctly in irb: irb(main):001:0> File.new('hatem.jpg').mtime => Tue Mar 09 16:56:38 +0200 2010 But when I try to use Paperclip's before_post_process: before_post_process :get_file_info def get_file_info puts File.new(self.media.to_file.path).mtime # =>Wed Apr 14 18:36:22 +0200 2010 end I get the current date instead of the capture date. How can I fix this? Also, how can I get the video duration and store it with the model? Thank you.
