PerformancePoint dashboard permissions problem in MOSS

- by Nathan DeWitt

I have a PerformancePoint dashboard running in MOSS 2007 portal. The dashboard consists of one SSRS 2005 report, running in SharePoint Integrated mode. NT Authority\Authenticated Users have read permissions to the report library containing the SSRS report, the dashboard, and the report library containing the dashboard. Users that attempt to access the dashboard receive the following error message: The permissions granted to user 'DOMAIN\firstname.lastname' are insufficient for performing this operation. (rsAccessDenied) Users that then click on the direct link to the report in MOSS will see the report with no problem. Subsequent visits to the dashboard show the report with no problem. The report is using a data source that is located one folder up from the report location. The report has been updated to point to the correct shared data source after deployment. Both the report and the data source have been published. The data source is using stored credentials, with a domain service account that has been set to Use as Windows credentials. This service account is serving other reports in other areas with no problem. Edit: Ok, I've gotten a lot more information on this problem. The request is never actually being made to the data source. The user comes in to the dashboard and requests a report for the first time using their kerberos token identifying themselves. The report looks in the Report Server database and finds that they are not listed in the users table and generates this rsAccessDenied error. Once they view the report directly their name is in this table and they never have the problem again. Unfortunately, removing the user from the Users table in the RS database doesn't actually cause this error to happen again. Everything I've read says that when you run a Report Server in MOSS integrated mode all your permissions are handled at the MOSS report library level, and all Auth users have permissions to the report library, as stated earlier. Any ideas?

RegistryKey ValueCount/SubKeyCount wrong

- by Mark J Miller

I am trying to query the following registry key values: HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SharedMemoryOn HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SuperSocketNetLib\ProtocolOrder But depending on which machine I'm running the program the query returns null. When I debug on my local machine and I inspect the value for ValueCount for: HKLM\SOFTWARE\Microsoft\MSSQLServer\Client HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\SuperSocketNetLib The count is 0 and OpenSubKey returns null. I am a domain admin, in the local administrators group and have added the following to my app.manifest: <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> Any idea why? private static void ValidateSqlClientSettings() { Console.WriteLine("\r\n/////////////// LOCAL SQL CLIENT PROTOCOLS ////////////////"); RegistryKey keyHKLM = Registry.LocalMachine; ///TODO: nullreferenceexception - connect to remote machine and find out why RegistryKey sqlClientKey = keyHKLM.OpenSubKey(@"SOFTWARE\Microsoft\MSSQLServer\Client"); if (sqlClientKey == null) { WriteLine2Console(@"WARNING: unable to read registry key '{0}\SOFTWARE\Microsoft\MSSQLServer\Client'", ConsoleColor.Yellow); } var cliKeyNames = from k in sqlClientKey.GetSubKeyNames() where k == "SuperSocketNetLib" select k; ///TODO: find out why these values are always missing (even if I can see them in regedit) Console.Write("Shared Memory Disabled (cliconfg): "); if (Convert.ToBoolean(sqlClientKey.GetValue("SharedMemoryOn"))) WriteLine2Console("FAILED", ConsoleColor.Red); else if(sqlClientKey.GetValue("SharedMemoryOn") == null) WriteLine2Console(String.Format("WARNING - unable to read '{0}\\SharedMemoryOn'", sqlClientKey.Name), ConsoleColor.Yellow); else WriteLine2Console("PASS", ConsoleColor.Green); Console.Write("Client Protocol Order (cliconfg - tcp first): "); foreach (string cliKey in cliKeyNames) { RegistryKey subKey = sqlClientKey.OpenSubKey(cliKey); object order = subKey.GetValue("ProtocolOrder"); if (order != null && order.ToString().StartsWith("tcp") == false) { WriteLine2Console("FAILED", ConsoleColor.Red); } else if (order == null) { WriteLine2Console(String.Format("WARNING - unable to read '{0}\\ProtocolOrder'", subKey.Name), ConsoleColor.Yellow); } else { WriteLine2Console("PASS", ConsoleColor.Green); } subKey.Close(); } sqlClientKey.Close(); keyHKLM.Close(); }

EF 4.0 : Save Changes Retry Logic

- by BGR

Hi, I would like to implement an application wide retry system for all entity SaveChanges method calls. Technologies: Entity framework 4.0 .Net 4.0 namespace Sample.Data.Store.Entities { public partial class StoreDB { public override int SaveChanges(System.Data.Objects.SaveOptions options) { for (Int32 attempt = 1; ; ) { try { return base.SaveChanges(options); } catch (SqlException sqlException) { // Increment Trys attempt++; // Find Maximum Trys Int32 maxRetryCount = 5; // Throw Error if we have reach the maximum number of retries if (attempt == maxRetryCount) throw; // Determine if we should retry or abort. if (!RetryLitmus(sqlException)) throw; else Thread.Sleep(ConnectionRetryWaitSeconds(attempt)); } } } static Int32 ConnectionRetryWaitSeconds(Int32 attempt) { Int32 connectionRetryWaitSeconds = 2000; // Backoff Throttling connectionRetryWaitSeconds = connectionRetryWaitSeconds * (Int32)Math.Pow(2, attempt); return (connectionRetryWaitSeconds); } /// <summary> /// Determine from the exception if the execution /// of the connection should Be attempted again /// </summary> /// <param name="exception">Generic Exception</param> /// <returns>True if a a retry is needed, false if not</returns> static Boolean RetryLitmus(SqlException sqlException) { switch (sqlException.Number) { // The service has encountered an error // processing your request. Please try again. // Error code %d. case 40197: // The service is currently busy. Retry // the request after 10 seconds. Code: %d. case 40501: //A transport-level error has occurred when // receiving results from the server. (provider: // TCP Provider, error: 0 - An established connection // was aborted by the software in your host machine.) case 10053: return (true); } return (false); } } } The problem: How can I run the StoreDB.SaveChanges to retry on a new DB context after an error occured? Something simular to Detach/Attach might come in handy. Thanks in advance! Bart

Prefuse: Reloading of XML files

- by John

Hello all, I am a new to the prefuse visualization toolkit and have a couple of general questions. For my purpose, I would like to perform an initial visualization using prefuse (graphview / graphml). Once rendered, upon a user click of a node, I would like to completely reload a new xml file for a new visualization. I want to do this in order to allow me to "pre-package" graphs for display. For example. If I search for Ted. I would like to have an xml file relating to Ted load and render a display. Now in the display I see that Ted has nodes associated called Bill and Joe. When I click Joe, I would like to clear the display and load an xml file associated with Joe. And so on. I have looked into loading one very large xml file containing all node and node relationship info and allowing prefuse to handle this using the hops from one level to another. However, eventually I am sure that system performance issues will arise due to the size of data. Thanks in advance for any help, John

python protobufs - avoid the install step ?

- by orion elenzil

i'm writing a small python utility which will be consumed by moderately non-technical users and which needs to interface w/ some protobufs. ideally, i would like the only prerequisites to using this on a local machine to be: have python installed * have an SVN checkout of the repository * run a simple bash script to build the local proto .py definitions * run "python myutility" i'm running into trouble around importing descriptor_pb2.py, tho. i've seen Why do I see "cannot import name descriptor_pb2" error when using Google Protocol Buffers? , but would like to avoid adding the additional prerequisite of having run the proto SDK installer. i've modified the bash script to also generate descriptor_pb2.py in the local heirarchy, which works for the first level of imports from my other _pb2.py files, but it looks like descriptor_pb2.py itself tries to import descriptor_pb2 can't find it: $ python myutility.py Traceback (most recent call last): File "myutility.py", line 4, in <module> import protos.myProto_pb2 File "/myPath/protos/myProto_pb2.py", line 8, in <module> from google.protobuf import descriptor_pb2 File "/myPath/google/protobuf/descriptor_pb2.py", line 8, in <module> from google.protobuf import descriptor_pb2 ImportError: cannot import name descriptor_pb2 my local folder looks like: * myutility.py * google/ * protobuf/ * descriptor.py * descriptor_pb2.py * protos * myProto_ob2.py also, i'm a python n00b, so it's possible i'm overlooking something obvious. tia, orion

Perf4j Not Logging to Separate File

- by Jehud

I setup some stop watch calls in my code to measure some code blocks and all the messages are going into my primary log and not into the timing log. The perfStats.log file gets created just fine but all the messages go to the root log which I didn't think was supposed to happen according to the docs I've read. Is there something obvious I'm missing here? Example log4j.xml  <appender name="fileAppender" class="org.apache.log4j.FileAppender"> <param name="File" value="perfStats.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%m%n"/> </layout> </appender>   <logger name="org.perf4j.TimingLogger" additivity="false"> <level value="INFO"/> <appender-ref ref="CoalescingStatistics"/> </logger> <root> <priority value="info"/> <appender-ref ref="STDOUT-DEBUG"/> </root>

Is there a way in .NET to access the bytecode/IL/CLR that is currently running?

- by Alix

Hi. I'd like to have access to the bytecode that is currently running or about to run in order to detect certain instructions and take specific actions (depending the instructions). In short, I'd like to monitor the bytecode in order to add safety control. Is this possible? I know there are some AOP frameworks that notify you of specific events, like an access to a field or the invocation of a method, but I'd like to skip that extra layer and just look at all the bytecode myself, throughout the entire execution of the application. I've already looked at the following questions (...among many many others ;) ): Preprocessing C# - Detecting Methods What CLR/.NET bytecode tools exist? as well as several AOP frameworks (although not in great detail, since they don't seem to do quite what I need) and I'm familiar with Mono.Cecil. I appreciate alternative suggestions, but I don't want to introduce the overhead of an AOP framework when what I actually need is access to the bytecode, without all the stuff they add on top to make it more user-friendly (... admittedly very useful stuff when you don't want to go low-level). Thanks :)

How to make Nlog archive a file with the date when the logging took place.

- by Carl Bergquist

Hi, We are using Nlog as our logging framework and I cannot find a way to archive files the way I want. I would like to have the date of when the logging took place in the logging file name. Ex All logging that happend from 2009-10-01 00:00 -> 2009-10-01:23:59 should be placed in Log.2009-10-01.log The current NLog.config that I use looks like this. <?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <extensions> <add assembly="My.Awesome.LoggingExentions"/> </extensions> <targets> <target name="file1" xsi:type="File" fileName="${basedir}/Logs/Log.log" layout="${longdate} ${level:uppercase=true:padding=5} ${session} ${storeid} ${msisdn} - ${logger:shortName=true} - ${message} ${exception:format=tostring}" archiveEvery="Day" archiveFileName="${basedir}/Logs/Log${shortdate}-{#}.log" archiveNumbering="Sequence" maxArchiveFiles="99999" keepFileOpen="true" /> </targets> <rules> <logger name="*" minlevel="Trace" writeTo="file1" /> </rules> </nlog> This however sets the date in the logfile to the date when the new logfile is created. Which cause frustration when you want to read logs later. It also seems like I have to have atleast on # in the archiveFileName, which I rather not. So if you got a solution for that also I would be twice as thankful =)

Compiler optimization causing the performance to slow down

- by aJ

I have one strange problem. I have following piece of code: template<clss index, class policy> inline int CBase<index,policy>::func(const A& test_in, int* srcPtr ,int* dstPtr) { int width = test_in.width(); int height = test_in.height(); double d = 0.0; //here is the problem for(int y = 0; y < height; y++) { //Pointer initializations //multiplication involving y //ex: int z = someBigNumber*y + someOtherBigNumber; for(int x = 0; x < width; x++) { //multiplication involving x //ex: int z = someBigNumber*x + someOtherBigNumber; if(soemCondition) { // floating point calculations } *dstPtr++ = array[*srcPtr++]; } } } The inner loop gets executed nearly 200,000 times and the entire function takes 100 ms for completion. ( profiled using AQTimer) I found an unused variable double d = 0.0; outside the outer loop and removed the same. After this change, suddenly the method is taking 500ms for the same number of executions. ( 5 times slower). This behavior is reproducible in different machines with different processor types. (Core2, dualcore processors). I am using VC6 compiler with optimization level O2. Follwing are the other compiler options used : -MD -O2 -Z7 -GR -GX -G5 -X -GF -EHa I suspected compiler optimizations and removed the compiler optimization /O2. After that function became normal and it is taking 100ms as old code. Could anyone throw some light on this strange behavior? Why compiler optimization should slow down performance when I remove unused variable ? Note: The assembly code (before and after the change) looked same.

Create a VPN with Python

- by user213060

I want to make a device "tunnel box" that you plug an input ethernet line, and an output ethernet line, and all the traffic that goes through it gets modified in a special way. This is similar to how a firewall, IDS, VPN, or similar boxes are connected inline in a network. I think you can just assume that I am writing a custom VPN in Python for the purpose of this question: LAN computer <--\ LAN computer <---> [LAN switch] <--> ["tunnel box"] <--> [internet modem] <--> LAN computer <--/ My question is, what is a good way to program this "tunnel box" from python? My application needs to see TCP flows at the network layer, not as individual ethernet frames. Non-TCP/IP traffic such as ICPM and other types should just be passed through. Example Twisted-like Code for my "tunnel box" tunnel appliance: from my_code import special_data_conversion_function class StreamInterceptor(twisted.Protocol): def dataReceived(self,data): data=special_data_conversion_function(data) self.outbound_connection.send(data) My initial guesses: TUN/TAP with twisted.pair.tuntap.py - Problem: This seems to only work at the ethernet frame level, not like my example? Socks proxy - Problem: Not transparent as in my diagram. Programs have to be specifically setup for it. Thanks!

is delete p where p is a pointer to array a memory leak ?

- by Eli

following a discussion in a software meeting I setup to find out if deleting an dynamically allocated primitive array with plain delete will cause a memory leak. I have written this tiny program and compiled with visual studio 2008 running on windows XP: #include "stdafx.h" #include "Windows.h" const unsigned long BLOCK_SIZE = 1024*100000; int _tmain() { for (unsigned int i =0; i < 1024*1000; i++) { int* p = new int[1024*100000]; for (int j =0;j<BLOCK_SIZE;j++) p[j]= j % 2; Sleep(1000); delete p; } } I than monitored the memory consumption of my application using task manager, surprisingly the memory was allocated and freed correctly, allocated memory did not steadily increase as was expected I've modified my test program to allocate a non primitive type array : #include "stdafx.h" #include "Windows.h" struct aStruct { aStruct() : i(1), j(0) {} int i; char j; } NonePrimitive; const unsigned long BLOCK_SIZE = 1024*100000; int _tmain() { for (unsigned int i =0; i < 1024*100000; i++) { aStruct* p = new aStruct[1024*100000]; Sleep(1000); delete p; } } after running for for 10 minutes there was no meaningful increase in memory I compiled the project with warning level 4 and got no warnings. is it possible that the visual studio run time keep track of the allocated objects types so there is no different between delete and delete[] in that environment ?

Apache rewrite rules redux

- by AlexanderJohannesen

I've got a REST framework that when plopped into any directory should Just Work(TM), and it seems to work fine when I've got projects in subdirectories, but not if it's in root. So, given a few example directories; / /project1 /bingo/project2 /hoopla/doopla/minor/project3 All of these works fine, except I'm getting "funnies"* when the project runs in the root directory (bit hard to explain, I suppose, but the second level rewrites are not working properly). Here's my attempt at a generic .htaccess file: RewriteEngine On RewriteRule ^static/ - [L] RewriteCond %{REQUEST_URI} ^$ RewriteRule .* ./ [R,L] RewriteRule ^index.php - [L] RewriteRule (.*) index.php?q=$1 [QSA,PT] (And yes, all projects have a subdirectory ./static which is ignored by rewrites) What I'm trying to achieve is a set of rewrite rules that work for most cases (which is, again, plonking the project in a directory the webserver serves). I'm not a rewrite rules wiz by a long shot, and any good advice and gotchas would be appreciated (and yes, I've gone through too many introductory articles. I need some serious juice.) More info on the funnies; my webserver has docroot in one spot (under /usr/share/apache2/default-site/), but a set of rules that says that /projects is pulled in from somewhere else that's not a subdirectory of docroot (/home/user/Projects/). When I go there, I get a list of /projects subdirectories, and if one of those subdirectories gets called (restmapp) with the proposed rewrite rules, I get ; The requested URL /home/user/Projects/restmapp/index.php was not found on this server.

Why does Java's invokevirtual need to resolve the called method's compile-time class?

- by Chris

Consider this simple Java class: class MyClass { public void bar(MyClass c) { c.foo(); } } I want to discuss what happens on the line c.foo(). At the bytecode level, the meat of c.foo() will be the invokevirtual opcode, and, according to the documentation for invokevirtual, more or less the following will happen: Look up the foo method defined in compile-time class MyClass. (This involves first resolving MyClass.) Do some checks, including: Verify that c is not an initialization method, and verify that calling MyClass.foo wouldn't violate any protected modifiers. Figure out which method to actually call. In particular, look up c's runtime type. If that type has foo(), call that method and return. If not, look up c's runtime type's superclass; if that type has foo, call that method and return. If not, look up c's runtime type's superclass's superclass; if that type has foo, call that method and return. Etc.. If no suitable method can be found, then error. Step #3 alone seems adequate for figuring out which method to call and verifying that said method has the correct argument/return types. So my question is why step #1 gets performed in the first place. Possible answers seem to be: You don't have enough information to perform step #3 until step #1 is complete. (This seems implausible at first glance, so please explain.) The linking or access modifier checks done in #1 and #2 are essential to prevent certain bad things from happening, and those checks must be performed based on the compile-time type, rather than the run-time type hierarchy. (Please explain.)

Why do people hate SQL cursors so much?

- by Steven A. Lowe

I can understand wanting to avoid having to use a cursor due to the overhead and inconvenience, but it looks like there's some serious cursor-phobia-mania going on where people are going to great lengths to avoid having to use one for example, one question asked how to do something obviously trivial with a cursor and the accepted answer proposed using a common table expression (CTE) recursive query with a recursive custom function, even though this limits the number of rows that could be processed to 32 (due to recursive call limit in sql server). This strikes me as a terrible solution for system longevity, not to mention a tremendous effort just to avoid using a simple cursor. what is the reason for this level of insane hatred? has some 'noted authority' issued a fatwa against cursors? does some unspeakable evil lurk in the heart of cursors that corrupts the morals of the children or something? wiki question, more interested in the answer than the rep thanks in advance! Related Info: http://stackoverflow.com/questions/37029/sql-server-fast-forward-cursors EDIT: let me be more precise: I understand that cursors should not be used instead of normal relational operations, that is a no-brainer. What I don't understand is people going waaaaay out of their way to avoid cursors like they have cooties or something, even when a cursor is a simpler and/or more efficient solution. It's the irrational hatred that baffles me, not the obvious technical efficiencies.

Globally disabling FxCop errors in TeamCity

- by Dave

Ok, another FxCop question for today. I've read the arguments regarding the IdentifiersShouldBeCasedCorrectly rule, and whether or not it should be "XML" or "Xml". Well, I'm an "XML" guy and I want to stay that way. Therefore, I do not want FxCop to correct me all of the time. I have been using the SuppressMessage attribute only for specific cases. I have also used FxCop to mark a ton of errors and copied them as "module" level SuppressMessage statements into assemblyinfo.cs. That works pretty well. However, now I really want to globally disable this annoying IdentifiersShouldBeCasedCorrectly rule. I'm using TeamCity 5.0.3, and am not using an FxCop project file (however, I could do this). I was hoping that I could pass a parameter to FxCopCmd to tell it to ignore this error, but it doesn't look that way from the documentation. So... is there anything I can do short of creating an FxCop project file on the TeamCity build server and using it for the FxCop build runner?

Readability and IF-block brackets: best practice

- by MasterPeter

I am preparing a short tutorial for level 1 uni students learning JavaScript basics. The task is to validate a phone number. The number must not contain non-digits and must be 14 digits long or less. The following code excerpt is what I came up with and I would like to make it as readable as possible. if ( //set of rules for invalid phone number phoneNumber.length == 0 //empty || phoneNumber.length > 14 //too long || /\D/.test(phoneNumber) //contains non-digits ) { setMessageText(invalid); } else { setMessageText(valid); } A simple question I can not quite answer myself and would like to hear your opinions on: How to position the surrounding (outermost) brackets? It's hard to see the difference between a normal and a curly bracket. Do you usually put the last ) on the same line as the last condition? Do you keep the first opening ( on a line by itself? Do you wrap each individual sub-condition in brackets too? Do you align horizontally the first ( with the last ), or do you place the last ) in the same column as the if? Do you keep ) { on a separate line or you place the last ) on the same line with the last sub-condition and then place the opening { on a new line? Or do you just put the ) { on the same line as the last sub-condition? Community wiki. EDIT Please only post opinions regarding the usage and placement of brackets. The code needs not be re-factored. This is for people who have only been introduced to JavaScript a couple of weeks ago. I am not asking for opinions how to write the code so it's shorter or performs better. I would only like to know how do you place brackets around IF-conditions.

When does a WPF adorner layer first become available?

- by aoven

I'm trying to add an overlay effect to my UserControl and I know that's what adorners are used for in WPF. But I'm a bit confused about how they supposedly work. I figured that adorner layer is implicitly handled by WPF runtime, and as such, should always be available. But when I create an instance of my UserControl in code, there is no adorner layer there. The following code fails with exception: var view = new MyUserControl(); var target = view.GetAdornerTarget(); // This returns a specific UI control. var layer = AdornerLayer.GetAdornerLayer(target); if (layer == null) { throw new Exception("No adorner layer at the moment."); } Can someone please explain to me, how this is supposed to work? Do I need to place the UserControl instance into a top-level Window first? Or do I need to define the layer myself somehow? Digging through documentation got me nowhere. Thank you!

What programming languages do the top tier Universities teach?

- by Simucal

I'm constantly being inundated with articles and people talking about how most of today's Universities are nothing more than Java vocational schools churning out mediocre programmer after mediocre programmer. Our very own Joel Spolsky has his famous article, "The Perils of Java Schools." Similarly, Alan Kay, a famous Computer Scientist (and SO member) has said this in the past: "I fear — as far as I can tell — that most undergraduate degrees in computer science these days are basically Java vocational training." - Alan Kay (link) If the languages being taught by the schools are considered such a contributing factor to the quality of the school's program then I'm curious what languages do the "top-tier" computer science schools teach (MIT, Carnegie Mellon, Stanford, etc)? If the average school is performing so poorly due in large part the languages (or lack of) that they teach then what languages do the supposed "good" cs programs teach that differentiate them? If you can, provide the name of the school you attended, followed by a list of the languages they use throughout their coursework. Edit: Shog-9 asks why I don't get this information directly from the schools websites themselves. I would, but many schools websites don't discuss the languages they use in their class descriptions. Quite a few will say, "using high-level languages we will...", without elaborating on which languages they use. So, we should be able to get a pretty accurate list of languages taught at various well known institutions from the various SO members who have attended at them.

Not all TFS Build type files are getting copied

- by k4k4sh1

Because I have several builds sharing some assemblies containing common build tasks, I have one TFSBuild.proj for all builds and import different targets depending on the build, like the following: <Project DefaultTargets="DesktopBuild" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="3.5"> <Import Project="Build_1.targets" Condition="'$(BuildDefinition)'=='Build_1'" /> <Import Project="Build_2.targets" Condition="'$(BuildDefinition)'=='Build_2'" /> <Import Project="Build_3.targets" Condition="'$(BuildDefinition)'=='Build_3'" /> </Project> Each target for a particular build has your usual content for a build type file, but in my case, I also reference some tasks inside assemblies checked into the same folder as TFSBuild.proj in source control. I wanted to add folders to contain some test build targets, since my folder was getting a bit full and cluttered. The following illustrates what I mean. $(TFS project)\build\ TFSBuild.proj Build_1.targets ... Assembly1.dll Assembly2.dll ... Folder\ Test_target_1.targets .... When I stated my build, however, I found that Test_target_1.targets and other files in Folder were not being copied to the build directory, while TFSBuild.proj and other files in the root level, as it were, of the build type folder were being copied. This caused my test build to not be able to reference files inside Folder, causing my build to immediately fail. I realize the simplest work-around would be to get rid of Folder and move all of its contents up to the build folder, but I would really like to have Folder if at all possible. Thanks for your help in advance.

MVC View Model Intellisense / Compile error

- by Marty Trenouth

I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed. Controller: return View(new TeraViral_Blog()); View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<com.models.TeraViral_Blog>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Index2 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Index2</h2> <fieldset> <legend>Fields</legend> <p> ID: <%= Html.Encode(Model.ID) %> </p> </fieldset> </asp:Content>

fluent nHibernate mapping of subclassed structure

- by Codezy

I have a workflow class that has a collection of phases, each phase has a collection of tasks. You can design a workflow that will be used by many engagements. When used in engagement I want to be able to add properties to each class (workflow, phase, and task). For example a task in the designer does not have people assigned, but a task in an engagement would need extra properties like who is assigned to it. I have tried many different approaches using subclasses or interfaces but I just can't get it to map the way I want. Currently I have the engagement level versions as subclasses, but I can't get Engagement phases to map to engagement workflows. Public Class WorkflowMapping Inherits ClassMap(Of Workflow) Sub New() Id(Function(x As Workflow) x.Id).Column("Workflow_Id").GeneratedBy.Identity() Map(Function(x As Workflow) x.Description) Map(Function(x As Workflow) x.Generation) Map(Function(x As Workflow) x.IsActive) HasMany(Function(x As Workflow) x.Phases).Cascade.All() End Sub End Class Public Class EngagementWorkflowMapping Inherits SubclassMap(Of EngagementWorkflow) Sub New() Map(Function(x As EngagementWorkflow) x.ClientNo) Map(Function(x As EngagementWorkflow) x.EngagementNo) End Sub End Class How would you approach mapping this in fluent (or hbm) so that you could load just the workflow base class when designing the flow, or the engagement subclass versions of each when being used by an engagement?

WPF: How do I get a reference to a styled window control in code behind?

- by Brad

I have a window defined with a style: <Window x:Class="winBorderless" x:Name="winBorderless" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Local="clr-namespace:WindowStyle" Style="{StaticResource Window_Cartesia}" WindowStartupLocation="CenterScreen" BorderThickness="1" BorderBrush="#FF9CAAC1" Margin="5" Title="[Document Title]"> and the style defined in an application level dictionary: <Style x:Key="Window_Cartesia" TargetType="{x:Type Window}"> <Setter Property="WindowStyle" Value="None"/> <Setter Property="AllowsTransparency" Value="True"/> <Setter Property="Background" Value="Transparent"/> <EventSetter Event="Loaded" Handler="Loaded"/> <EventSetter Event="PreviewKeyDown" Handler="Preview_KeyDown"/> <EventSetter Event="MouseMove" Handler="FullScreen_MouseMove"/> <Setter Property="Template"> In code behind I have a reference to the Window instance set: Win = DirectCast(sender, winBorderless) This allows access to the window properties as the EventSetters pass references to the various controls. However, it doesn't provide for access to the controls defined in the style through the window reference as they don't exist there. So, what is the best way to reference a control through code behind that is defined in the style. I'd prefer not to iterate the trees to find them but ya gotta do....
