• Delphi Prism and LINQ to SQL / Entity Framework

  - by Vegar

  I have found many posts and examples of using LINQ-syntax in Delphi Prism (Oxygene), but I have never found anything on LINQ to SQL or Entity Framework. Is it possible to use LINQ to SQL or Entity Framework together with Prism? Where can I found such an example? Update: Olaf is giving an answer through his blog The question is now if any visual tools and code generation is provided, or if everything must be done by hand... Second update: Olaf has answered the tool/code generation-question in a comment on his site: The class designer is there, but there is no Pascal code gen. According to marc hoffman that is currently not on their list. For now you have to live with manual mapping. I guess, if you had Visual Studio (not just the VS shell), that you could add a C# library project to your solution, reference that from your Prism project. Then create the Table-Class mapping in the C# project using the visual designer. Maybe somewhat ugly, but possibly the key to get the Designer + CodeGen integrated into Prism. Who cares what language is used for the mapping . I will say this is a 1 - 0 to c# vs prism. If I did not care which language is used for the mapping - why should I care about which language is used for the rest?

• Code to connect to remote server using perl

  I'm written small code to connect to remote server using perl but observing error messages #!/usr/bin/perl -w use Net::Telnet; $telnet = new Net::Telnet ( Timeout=>60, Errmode=>'die'); $telnet->open('192.168.50.40'); $telnet->waitfor('/login:/'); $telnet->print('queen'); $telnet->waitfor('/password:/'); $telnet->print('kinG!'); $telnet->waitfor('/:/'); $telnet->print('vol >> C:\result.txt'); $telnet->waitfor('/:/'); $telnet->cmd("mkdir vol"); $telnet->print('mkdir vol234'); $telnet->cmd("mkdir vol1"); $telnet->waitfor('/\$ $/i'); $telnet->print('whoamI'); print $output; But while running i'm getting following errors C:\>perl -c E:\test\net.pl E:\test\net.pl syntax OK C:\>perl E:\test\net.pl command timed-out at E:\test\net.pl line 13 C:\> Help me in this regard.. i'm not much aware of perl

• Magento Developers: Is Magento really -that- good?

  - by Kevin

  We are looking at Magento as a possible commerce solution, but we are reading more bad than good on the free product. However Magento sells itself as the best thing ever, so I am confused on its actual value. Thought I'd ask the pros here. Can any seasoned developer here explain the difficulties in using Magento not only as a commerce solution, but a CMS solution? Can it do easy content management like Drupal, Joomla, etc? If I wanted a custom list of products, is that simple or do you have to spend hours learning where to create the code? Is it modular in the way Drupal is where you can say, here is my custom code, and interact with Magento and change some of its function? Is it difficult to conceive how it works from a developer, user, and customer standpoint? We don't use Zend Framework and are not familiar with Smarty syntax (which I think Magento uses for templating). The risk in my mind is that the learning curve will be really steep (especially for the designers), and trouble tickets may take a long time to resolve (resulting in some pissed off customers). Any thoughts from people who have used Magento extensively?

• using Quick Sequence Diagram Editor for sequence diagrams

  - by Jason S

  Anyone have experience with Quick Sequence Diagram Editor? The combination of instant display + text source code + Java implementation is very attractive to me, but I can't quite figure out how to make the syntax do what I want, and the documentation's not very clear. Here's a contrived example: al:Actor bill:Actor atm:ATM[a] bank:Bank[a] al:atm.give me $10 atm:al has $3=bank.check al's account balance al:atm.what time is it atm:al.it's now atm:al.stop bugging me atm:al.you only have $3 atm:bill.and don't you open your mouth bill:atm.who asked you? bill:atm.give me $20 al:atm.hey, I'm not finished! atm:bill has $765=bank.check bill's account balance atm:yes I'm sure, bill has $765=bank.hmm are you sure? atm:bill.here's $20, now go away atm:great, he's a cool dude=bank.I just gave Bill $20 al:atm.what about my $10? atm:al.read my lips: you only have $3 Here's the result from QSDE in single-threaded mode: and in multi-threaded mode: I guess I'm not clear what starts/ends those vertical bars. I have a situation which is single-threaded, but there's state involved, and all the messages are asynchronous. I guess that means I should use an external object to represent that state and its lifetime. What I want is for one timeline to represent the message sequence al:atm.give me $10 atm:bank.check al's account balance bank:atm.al has $3 atm:al.you only have $3 and another timeline to represent the message sequence bill:atm.give me $20 atm:bank.check bill's account balance bank:atm.bill has $765 atm:bank.hmm are you sure? bank:atm.yes I'm sure, bill has $765 atm:bill.here's $20, now go away atm:bank.I just gave Bill $20 bank:atm.great, he's a cool dude with the other "wisecracks" representing other miscellaneous messages that I don't care about right now. Is there a way to do this with QSDE?

• Posting a JSON array to webservice in Android

  - by Sam

  I am having some problems with what should be a rather simple task. I simply need a JSON array with a single JSON object within it to be posted to my webservice. The entire URL request needs to be formatted like this: http://www.myserver.com/myservice.php?location_data=[{"key1":"val1","key2":"val2"....}] I cannot for the life of me figure out how to append the 'location_data' bit using HttpPost. Here is a code snippet to demonstrate the HTTP connection method I am using: HttpClient hClient = new DefaultHttpClient(); HttpPost hPost = new HttpPost(url); try { hPost.setEntity(new StringEntity(string)); hPost.setHeader("Accept", "application/json"); hPost.setHeader("Content-type", "application/json"); //execute request HttpResponse response = (HttpResponse) hClient.execute(hPost); HttpEntity entity = response.getEntity(); I don't have any syntax errors, and my code is accessing the server fine, just not in the exact format the server needs. Any help on how to format my request to look like how I need it would be greatly appreciated!

• Tables created programmatically don't appear in WebBrowser control

  - by John Hall

  I'm creating HTML dynamically in a WebBrowser control. Most elements seems to appear correctly, with the exception of a table. My code is: var doc = webBrowser1.Document; var body = webBrowser1.Document.Body; body.AppendChild(webBrowser1.Document.CreateElement("hr")); var div = doc.CreateElement("DIV"); var table = doc.CreateElement("TABLE"); var row1 = doc.CreateElement("TR"); var cell1 = doc.CreateElement("TD"); cell1.InnerText = "Cell 1"; row1.AppendChild(cell1); var cell2 = doc.CreateElement("TD"); cell2.InnerText = "Cell 2"; row1.AppendChild(cell2); table.AppendChild(row1); div.AppendChild(table); body.AppendChild(div); body.AppendChild(webBrowser1.Document.CreateElement("hr")); The HTML tags are visible in the OuterHTML property of the body, but all that appears in the browser are the two horizontal rules. If I replace div.AppendChild(table); with div.InnerHtml = table.OuterHtml then everything appears as expected.

• jquery Plugins/Validation using submitHandler

  - by Eyla

  Greeting, I'm using jquery Plugins/Validation library. I want to allow validation on submitting but I'm not sure where I should insert the code: I know that I can user submitHandler for that but after reading the document I had hard time to implement it so I need your help guys. jquery validation is working ok but the problem that the form still submitted even there are invalid inputs. here is my validation function and I want to know how can I make it to not submit the form if there is invalid input. by the way, I'm using asp.net button for submitting the form. here is my code: $(document).ready(function() { $("#aspnetForm").validate({ rules: { "<%=txtHomePhone.UniqueID %>": { phonehome: true }, "<%=txtMobileHome.UniqueID %>": { mobilephone: true }, "<%=txtFaxHome.UniqueID %>": { faxhome: true }, "<%=txtEmailHome.UniqueID %>": { email: true }, "<%=txtZipCodeHome.UniqueID %>": { ziphome: true }, //work "<%=txtPhonework.UniqueID %>": { phonework: true }, "<%=txtMobileWork.UniqueID %>": { mobilework: true }, "<%=txtFaxWork.UniqueID %>": { faxwork: true }, "<%=txtEmailWork.UniqueID %>": { email: true }, "<%=txtWebSite.UniqueID %>": { url: true }, "<%=txtZipWork.UniqueID %>": { zipwork: true } }, errorElement: "mydiv", wrapper: "mydiv", // a wrapper around the error message errorPlacement: function(error, element) { offset = element.offset(); error.insertBefore(element) error.addClass('message'); // add a class to the wrapper error.css('position', 'absolute'); error.css('left', offset.left + element.outerWidth()); error.css('top', offset.top - (element.height() / 2)); } });

• antlr grammar multiple alternatives

  - by joe

  I have this simple grammar for a C# like syntax. I can't figure out any way to separate fields and methods. All the examples I've seen for parsing C# combine fields and methods in the same rule. I would like to split them up as my synatx is pretty simple. grammar test; options { language =CSharp2; k = 3; output = AST; } SEMI : ';' ; LCURLY : '{' ; RCURLY : '}' ; LPAREN : '(' ; RPAREN : ')' ; DOT :'.'; IDENTIFIER : ( 'a'..'z' | 'A'..'Z' | '_' ) ( 'a'..'z' | 'A'..'Z' | '_' | '0'..'9' )* ; namespaceName : IDENTIFIER (DOT IDENTIFIER)* ; classDecl : 'class' IDENTIFIER LCURLY (fieldDecl | methodDecl)* RCURLY ; fieldDecl : namespaceName IDENTIFIER SEMI; methodDecl : namespaceName IDENTIFIER LPAREN RPAREN SEMI; I always end up wit this warning Decision can match input such as "IDENTIFIER DOT IDENTIFIER" using multiple alternatives: 1, 2

• Modify python USB device driver to only use vendor_id and product_id, excluding BCD

  - by Tony

  I'm trying to modify the Android device driver for calibre (an e-book management program) so that it identifies devices by only vendor id and product id, and excludes BCD. The driver is a fairly simply python plugin, and is currently set up to use all three numbers, but apparently, when Android devices use custom Android builds (ie CyanogenMod for the Nexus One), it changes the BCD so calibre stops recognizing it. The current code looks like this, with a simple list of vendor id's, that then have allowed product id's and BCD's with them: VENDOR_ID = { 0x0bb4 : { 0x0c02 : [0x100], 0x0c01 : [0x100]}, 0x22b8 : { 0x41d9 : [0x216]}, 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, 0x04e8 : { 0x681d : [0x0222]}, } The line I'm specifically trying to change is: 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, Which is, the line for identifying a Nexus One. My N1, running CyanogenMod 5.0.5, has the BCD 0x0226, and rather than just adding it to the list, I'd prefer to eliminate the BCD from the recognition process, so that any device with vendor id 0x18d1 and product id 0x4e11 or 0x4e12 would be recognized. The custom Android rom doesn't change enough for the specifics to matter. The syntax seems to require the BCD in brackets. How can I edit this so that it matches anything in that field?

• alphanumeric and special character sorting

  - by Kaushik Gopal

  Hi ppl, I wanted to know the different standards of sorting. To be more specific take the sample set: (Please note there's capitals, small letters, special characters, null values and numbers here) A a 3F Zx - 1Ad NULL How would the Oracle Database sort this by default? How would LINQ sort this by default? How would db2 sort this by default? (the following may get even more vague) How does the Windows platform sort this? (I mean say you have a couple of filenames, by default how would this get treated in a name sort) How does the *nix platform sort this? Is there some sort of standard for alphanumeric/special character sorting? The Windows operating system orders with numbers first, then alphabets. The Oracle database however treats alphabets first. I'm not sure of the *nix platform. It would be nice to have one place to know all these rules for the most common platforms (listed in questions above). Would the gurus throw some light on this topic? Cheers, K

• Need help limiting a join in Transact-sql

  - by MsLis

  I'm somewhat new to SQL and need help with query syntax. My issue involves 2 tables within a larger multi-table join under Transact-SQL (MS SQL Server 2000 Query Analyzer) I have ACCOUNTS and LOGINS, which are joined on 2 fields: Site & Subset. Both tables may have multiple rows for each Site/Subset combination. ACCOUNTS: | LOGINS: SITE SUBSET FIELD FIELD FIELD | SITE SUBSET USERID PASSWD alpha bravo blah blah blah | alpha bravo foo bar alpha charlie blah blah blah | alpha bravo bar foo alpha charlie bleh bleh blue | alpha charlie id ego delta bravo blah blah blah | delta bravo john welcome delta foxtrot blah blah blah | delta bravo jane welcome | delta bravo ken welcome | delta bravo barbara welcome I want to select all rows in ACCOUNTS which have LOGIN entries, but only 1 login per account. DESIRED RESULT: SITE SUBSET FIELD FIELD FIELD USERID PASSWD alpha bravo blah blah blah foo bar alpha charlie blah blah blah id ego alpha charlie bleh bleh blue id ego delta bravo blah blah blah jane welcome I don't really care which row from the login table I get, but the UserID and Password have to correspond. [Don't return invalid combinations like foo/foo or bar/bar] MS Access has a handy FIRST function, which can do this, but I haven't found an equivalent in TSQL. Also, if it makes a difference, other tables are joined to ACCOUNTS, but this is the only use of LOGINS in the structure. Thank you very much for any assistance.

• How do you keep all your languages straight?

  - by Chris Blackwell

  I think I'm going a little crazy. Right now, I'm working with the following languages (I was just doing a mental inventory): C++ - our game engine Assembler - low level debugging and a few co-processor specific routines Lua - our game engine scripting language HLSL - for shaders Python - our build system and utility tools Objective C/C++ - game engine platform code for Mac and iPhone C# - A few tools developed in our overseas office ExtendScript - Photoshop exporting tools ActionScript - UI scripting VBScript - some spreadsheet related stuff PHP - some web related stuff SQL - some web and tool related stuff On top of this are the plethora of API's that often have many different ways of doing the same thing: std library, boost, .NET, wxWidgets, Cocoa, Carbon, native script libraries for Python, Lua, etc, OpenGL, Direct3d, GDI, Aqua, augh! I find myself inadvertently conflating languages and api's, not realizing what I'm doing until I get syntax errors. I feel like I can't possibly keep up with it, and I can't possibly be proficient in all of these areas. Especially outside the realm of C++ and Python, I find myself programming more by looking at manuals that from memory. Do you have a similar problem? Ideas for compartmentalizing so you're more efficient? Deciding where you want to stay proficient? Organizational tips? Good ways to remember when you switch from Lua to C++ you need to start using semi-colons again? Rants on how complicated we programmers have made things for ourselves? Any ideas welcome!

• Suggestions for displaying code on webpages, MUST use <br> for newline

  - by bguiz

  Hi, I want to post code snippets online (wordpress.com blog) - and have its whitespace formatted nicely. See the answers suggested by this other SO question: Those would be OK, except that I like to copy code to clip board or clip entire pages using Evernote - and they use either the <pre> tag or <table> (or both) to format the code. So I end up with text whose newlines and white spaces ignored, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } Which I find rather annoying myself. I find that if the code was formatted using <br> tags, they copy/ clip porperly, e.g. string url = "<a href=\"" + someObj.getUrl() + "\" target=\"_blank\">"; // single line comments // second single line override protected void OnLoad(EventArgs e) { if(Attributes["class"]&nbsp;!= null) { //_year.CssClass = _month.CssClass = _day.CssClass = Attributes["class"]; } base.OnLoad(e); } I find this annoying myself, so I don't want to inflict it upon others when I post my own code. Please suggest methods of posting code snippets online that are able to do this. I would like to emphasise that syntax highlighting capability is secondary to correct white space markup. Thank you

• How to call SQL Function with multiple parameters from C# web page

  - by Marshall

  I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this: String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = @ClientID AND LocationName = @LocationName ',10)"; SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection); Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default"; // Real code uses Location Name from user input SqlDataReader reader = Cmd.ExecuteReader(); When I do this, I get the following code from SQL profiler: exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationID nvarchar(20)', @ClientID=7,@LocationName=N'Default' When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists. exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20); SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationName nvarchar(20)', @ClientID=7,@LocationName=N'Default' I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function. Any ideas?

• Google maps API V3 code to V2 help.

  I've started working on a project to inject markers into a map with jQuery by looping through rows on a table in the page. After getting it working I realized that I was accessing the V3 API and using V3 syntax. I've been beating my head against a wall trying to get this working in google maps API V2. If someone could please take a look at my code and help that would be great! Thanks! You can see my little test in action at www.axtsweapons.com/maptest.html. Here is the JS code: <script type="text/javascript"> $(function() { var latlng = new google.maps.LatLng(45.440000,-122.630000); var settings = { zoom: 12, center: latlng, disableDefaultUI: false, mapTypeControl:false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $('tr').each(function(i) { var the_marker = new google.maps.Marker({ title: $(this).find('.views-field-title').text(), map: map, clickable: true, position: new google.maps.LatLng( parseFloat($(this).find('.views-field-latitude').text()), parseFloat($(this).find('.views-field-longitude').text()) ) }); var bounds = new google.maps.LatLngBounds(); var infowindow = new google.maps.InfoWindow({ content: $(this).find('.views-field-title').text() + $(this).find('.adr').text() }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.close(); infowindow.open(map, the_marker); }); }); }); </script>

• Pre Commit Hook for JSLint in Mercurial and Git

  - by jrburke

  I want to run JSLint before a commit into either a Mercurial or Git repo is done. I want this as an automatic step that is set up instead of relying on the developer (mainly me) remembering to run JSLint before-hand. I normally run JSLint while developing, but want to specify a contract on JS files that they pass JSLint before being committed to the repo. For Mercurial, this page spells out the precommit syntax, but the only variables that seem to be available are the parent1 and parent2 changeset IDs involved in the commit. What I really want are a list of file names that are involved with the commit, so that I can then choose the .js file and run jslint over them. Similar issue for GIT, the default info available as part of the precommit script seems limited. What might work is calling hg status/git status as part of the precommit script, parse that output to find JS files then do the work that way. I was hoping for something easier though, and I am not sure if calling status as part of a precommit hook reflect the correct information. For instance in Git if the changes files have not been added yet, but the git commit uses -a, would the files show up in the correct section of the git status output as being part of the commit set? Update: I got something working, it is visible here: http://github.com/jrburke/dvcs_jslint/

• Debuging CUDA kernels called from .NET code in VS2008, emulation mode

  - by Danny Varod

  CUDA has an option to compile code in emulation mode, which is supported in the .rules file they provide. I have C# .NET 3.5 SP1 code that calls a native dll, using DllImport, the native dll is compiled via VS2008 using nvcc and its function is to transfer memory from and to CUDA and to invoke CUDA kernels. When the CUDA kernels are correct, everything runs fine, but when there is a bug, I can only step in to the code until the title of the kernels and see the parameters they receive. (I enabled debugging native code in the startup-project's debug options.) I have tried compiling with emulation mode, however I get the CUDA error "mixed device execution" when calling the CUDA memcopy host--device. I tried switching the alloc+dealloc+memcopy with their equivalent non-CUDA versions, but then the same error occurs when invoking the kernels. What did I do wrong in my attempt to using the debug-emulation mode? P.S. I tried this on Vista x64 SP1 + VS2008, with the same solution complied in both x86 and x64, neither worked in emulation mode, both worked in non-emulation mode.

For example public partial class User : IEntity { public NameValueCollection CheckModel() { return GetRuleViolations(); } /// <summary> /// Method validates incoming data, by given rules in the if statement. /// </summary> /// <returns>NameValueCollection</returns> private NameValueCollection GetRuleViolations() { NameValueCollection errors = new NameValueCollection(); if (string.IsNullOrEmpty(Username)) errors.Add("Username", "A username is required"); // and so on return errors; } } Now what I want to try to do is add validation attributes to the fields. For example I want to try to add the required attribute to the field Username instead/in addtion of using the validation I currently have. My question is how can I achieve this because the dmbl file is auto generated. Or maybe it is not possible and should I use a different approach?

• Permission denied for cvs server via ssh

  - by NovumCoder

  I cant create a new project by importing a java project via eclipse onto my cvs server via internet. I created a directory as root called /priv/cvs/. Then i called "cvs -d /priv/cvs/ init". I created a user named cvs and a groups called cvs. The repository is owned by cvs and in group cvs. Then i created a user "ben" and his only group is cvs. I "chrooted" the user "ben" accessing only the cvs functionality by not allowing to access the server via ssh with password, only by using a public key which is added in his home directory on the server in file authorized_keys2. the contect of authorized_keys2 is as follows: no-port-forwarding,no-X11-forwarding,command="/usr/bin/cvs server" ssh-rsa [public_key_content] rsa-key Connecting to the server works pretty fine. Eclipse asks for the passphrase for the private key to connect to the server. Authentication works and eclipse is able to run cvs commands. But when importing my project by using Team-Share Project. I get the error: The server reported an error: Permission denied projectname: cvs server: cannot open /priv/cvs/CVSROOT/config: Permission denied projectname: Cannot access /priv/cvs/CVSROOT The access right for the cvs root (/priv/cvs/) is set to 770. Which means that the owner, which is cvs and the group participants of the group cvs are allowed to read and write. Why do i get Permission denied? When i set the folder to 777, which means read/write to ALL, then it works. But i dont want that. I only want cvs users read/write to this folder? Is there something i misunderstood about access rules?

• How to override ATTR_DEFAULT_IDENTIFIER_OPTIONS in Models in Doctrine?

  - by user309083

  Here someone explained that setting a 'primary' attribute for any row in your Model will override Doctrine_Manager's ATTR_DEFAULT_IDENTIFIER_OPTIONS attribute: http://stackoverflow.com/questions/2040675/how-do-you-override-a-constant-in-doctrines-models This works, however if you have a many to many relation whereby the intermediate table is created, even if you have set both columns in the intermediate to primary an error still results when Doctrine tries to place an index on the nonexistant 'id' column upon table creation. Here's my code: //Bootstrap // set the default primary key to be named 'id', integer, 4 bytes Doctrine_Manager::getInstance()->setAttribute( Doctrine_Core::ATTR_DEFAULT_IDENTIFIER_OPTIONS, array('name' => 'id', 'type' => 'integer', 'length' => 4)); //User Model class User extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('users'); } public function setUp() { $this->hasMany('Role as roles', array( 'local' => 'id', 'foreign' => 'user_id', 'refClass' => 'UserRole', 'onDelete' => 'CASCADE' )); } } //Role Model class Role extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles'); } public function setUp() { $this->hasMany('User as users', array( 'local' => 'id', 'foreign' => 'role_id', 'refClass' => 'UserRole' )); } } //UserRole Model class UserRole extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles_users'); $this->hasColumn('user_id', 'integer', 4, array('primary'=>true)); $this->hasColumn('role_id', 'integer', 4, array('primary'=>true)); } } Resulting error: SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'id' doesn't exist in table. Failing Query: "CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB". Failing Query: CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB I'm creating my tables using Doctrine::createTablesFromModels();

• Dynamics CRM Customer Portal Accelerator Installation

  - by saturdayplace

  (I've posted this question on the codeplex forums too, but have yet to get a response) I've got an on-premise installation of CRM and I'm trying to hook the portal to it. My connection string in web.config: <connectionStrings> <add name="Xrm" connectionString="Authentication Type=AD; Server=http://myserver:myport/MyOrgName; User ID=mydomain\crmwebuser; Password=thepassword" /> </connectionStrings> And my membership provider: <membership defaultProvider="CustomCRMProvider"> <providers> <add connectionStringName="Xrm" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" name="CustomCRMProvider" type="System.Web.Security.SqlMembershipProvider" /> </providers> </membership> Now, I'm super new to MS style web development, so please help me if I'm missing something. In Visual Studio 2010, when I go to Project ASP.NET Configuration it launches the Web Site Administration Tool. When I click the Security Tab there, I get the following error: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax. Parameter name: connectionString I can't see what I'm doing wrong here. Does the user mydomain\crmwebuser need certain permissions in the SQL database, or somewhere else? edit: On the home page of the Web Site Administration Tool, I have the following: **Application**:/ **Current User Name**:MACHINENAME\USERACCOUNT Which is obviously a different set of credentials than mydomain\crmwebuser. Is this part of the problem?
