• WCF AuthenticationService in IIS7 Error

  - by germandb

  I have a WCF Server running on IIS 7 using default application pool, with SSL activate, the services is installed in a SBS Server 2008. I implement client application services with wcf and SQL 2005 for setting the access control in my application. The application run under windows vista and is make with WPF. In my developer machine the application and the WCF services run well, the IIS i'm use for the trials is the local IIS 7 and the database is the SQL Server 2005 database hosting in my server. I'm using Visual Studio Project Designer to enable and configure client application services. using https://localhost/WcfServidorFundacion. When i'm change the authentication services location to https://WcfServices:5659/WcfServidorFundacion and recompile the application, the following error show up. Message: The web service returned the error status code: InternalServerError. Details of service failure: {"Message":" Error while processing your request ","StackTrace":"","ExceptionType":""} Stack Trace: en System.Net.HttpWebRequest.GetResponse() en System.Web.ClientServices.Providers.ProxyHelper.CreateWebRequestAndGetResponse(String serverUri, CookieContainer& cookies, String username, String connectionString, String connectionStringProvider, String[] paramNames, Object[] paramValues, Type returnType) InnerException: System.Net.WebException Message="Remote Server Error: (500) Interal Server Error." I can access the WCF service from the navigator using the url mentioned above and even make a webReference in my project. I make a capture of the response but I'cant post it because i don't have 10 reputation points I activate the error log in the IIS 7 server, and the result is a Warning in the ManagedPipilineHandler. I appreciate if any one can help me Errors & Warnings No.?

• How I can add JScroll bar to NavigableImagePanel which is an Image panel with an small navigation vi

  - by Sarah Kho

  Hi, I have the following NavigableImagePanel, it is under BSD license and I found it in the web. What I want to do with this panel is as follow: I want to add a JScrollPane to it in order to show images in their full size and let the users to re-center the image using the small navigation panel. Right now, the panel resize the images to fit them in the current panel size. I want it to load the image in its real size and let users to navigate to different parts of the image using the navigation panel.

• Issues with HLSL and lighting

  - by numerical25

  I am trying figure out whats going on with my HLSL code but I have no way of debugging it cause C++ gives off no errors. The application just closes when I run it. I am trying to add lighting to a 3d plane I made. below is my HLSL. The problem consist when my Pixel shader method returns the struct "outColor" . If I change the return value back to the struct "psInput" , everything goes back to working again. My light vectors and colors are at the top of the fx file // PS_INPUT - input variables to the pixel shader // This struct is created and fill in by the // vertex shader cbuffer Variables { matrix Projection; matrix World; float TimeStep; }; struct PS_INPUT { float4 Pos : SV_POSITION; float4 Color : COLOR0; float3 Normal : TEXCOORD0; float3 ViewVector : TEXCOORD1; }; float specpower = 80.0f; float3 camPos = float3(0.0f, 9.0, -256.0f); float3 DirectLightColor = float3(1.0f, 1.0f, 1.0f); float3 DirectLightVector = float3(0.0f, 0.602f, 0.70f); float3 AmbientLightColor = float3(1.0f, 1.0f, 1.0f); /*************************************** * Lighting functions ***************************************/ /********************************* * CalculateAmbient - * inputs - * vKa material's reflective color * lightColor - the ambient color of the lightsource * output - ambient color *********************************/ float3 CalculateAmbient(float3 vKa, float3 lightColor) { float3 vAmbient = vKa * lightColor; return vAmbient; } /********************************* * CalculateDiffuse - * inputs - * material color * The color of the direct light * the local normal * the vector of the direct light * output - difuse color *********************************/ float3 CalculateDiffuse(float3 baseColor, float3 lightColor, float3 normal, float3 lightVector) { float3 vDiffuse = baseColor * lightColor * saturate(dot(normal, lightVector)); return vDiffuse; } /********************************* * CalculateSpecular - * inputs - * viewVector * the direct light vector * the normal * output - specular highlight *********************************/ float CalculateSpecular(float3 viewVector, float3 lightVector, float3 normal) { float3 vReflect = reflect(lightVector, normal); float fSpecular = saturate(dot(vReflect, viewVector)); fSpecular = pow(fSpecular, specpower); return fSpecular; } /********************************* * LightingCombine - * inputs - * ambient component * diffuse component * specualr component * output - phong color color *********************************/ float3 LightingCombine(float3 vAmbient, float3 vDiffuse, float fSpecular) { float3 vCombined = vAmbient + vDiffuse + fSpecular.xxx; return vCombined; } //////////////////////////////////////////////// // Vertex Shader - Main Function /////////////////////////////////////////////// PS_INPUT VS(float4 Pos : POSITION, float4 Color : COLOR, float3 Normal : NORMAL) { PS_INPUT psInput; float4 newPosition; newPosition = Pos; newPosition.y = sin((newPosition.x * TimeStep) + (newPosition.z / 3.0f)) * 5.0f; // Pass through both the position and the color psInput.Pos = mul(newPosition , Projection ); psInput.Color = Color; psInput.ViewVector = normalize(camPos - psInput.Pos); return psInput; } /////////////////////////////////////////////// // Pixel Shader /////////////////////////////////////////////// //Anthony!!!!!!!!!!! Find out how color works when multiplying them float4 PS(PS_INPUT psInput) : SV_Target { float3 normal = -normalize(psInput.Normal); float3 vAmbient = CalculateAmbient(psInput.Color, AmbientLightColor); float3 vDiffuse = CalculateDiffuse(psInput.Color, DirectLightColor, normal, DirectLightVector); float fSpecular = CalculateSpecular(psInput.ViewVector, DirectLightVector, normal); float4 outColor; outColor.rgb = LightingCombine(vAmbient, vDiffuse, fSpecular); outColor.a = 1.0f; //Below is where the error begins return outColor; } // Define the technique technique10 Render { pass P0 { SetVertexShader( CompileShader( vs_4_0, VS() ) ); SetGeometryShader( NULL ); SetPixelShader( CompileShader( ps_4_0, PS() ) ); } } Below is some of my c++ code. Reason I am showing this is because it is pretty much what creates the surface normals for my shaders to evaluate. for the lighting for(int z=0; z < NUM_ROWS; ++z) { for(int x = 0; x < NUM_COLS; ++x) { int curVertex = x + (z * NUM_VERTSX); indices[curIndex] = curVertex; indices[curIndex + 1] = curVertex + NUM_VERTSX; indices[curIndex + 2] = curVertex + 1; D3DXVECTOR3 v0 = vertices[indices[curIndex]].pos; D3DXVECTOR3 v1 = vertices[indices[curIndex + 1]].pos; D3DXVECTOR3 v2 = vertices[indices[curIndex + 2]].pos; D3DXVECTOR3 normal; D3DXVECTOR3 cross; D3DXVec3Cross(&cross, &D3DXVECTOR3(v2 - v0),&D3DXVECTOR3(v1 - v0)); D3DXVec3Normalize(&normal, &cross); vertices[indices[curIndex]].normal = normal; vertices[indices[curIndex + 1]].normal = normal; vertices[indices[curIndex + 2]].normal = normal; indices[curIndex + 3] = curVertex + 1; indices[curIndex + 4] = curVertex + NUM_VERTSX; indices[curIndex + 5] = curVertex + NUM_VERTSX + 1; v0 = vertices[indices[curIndex + 3]].pos; v1 = vertices[indices[curIndex + 4]].pos; v2 = vertices[indices[curIndex + 5]].pos; D3DXVec3Cross(&cross, &D3DXVECTOR3(v2 - v0),&D3DXVECTOR3(v1 - v0)); D3DXVec3Normalize(&normal, &cross); vertices[indices[curIndex + 3]].normal = normal; vertices[indices[curIndex + 4]].normal = normal; vertices[indices[curIndex + 5]].normal = normal; curIndex += 6; } } and below is my c++ code, in it's entirety. showing the drawing and also calling on the passes #include "MyGame.h" //#include "CubeVector.h" /* This code sets a projection and shows a turning cube.

• Jdbc - Connect remote Mysql Database error

  I'm using JDBC to connect my program to a MySQL database. I already put the port number and yes, my database have permission to access.

• IIRF reverse proxy problem

  - by Sergei

  Hi everyone, We have a java application ( Atlassian Bamboo) running on port 8085 on Windows 2003. It is accessile as http: //bamboo:8085. I am trying to setup reverse proxy for IIS6 using IIRF so content is accessible via http: //bamboo. It seems that I set it ip correctly, and I can retrieve Status page. This is how my IIRF.ini looks like: RewriteLog c:\temp\iirf RewriteLogLevel 2 StatusUrl /iirfStatus RewriteCond %{HTTP_HOST} ^bambooi$ [I] #This setup works #ProxyPass ^/(.*)$ http://othersite/$1 #This does not ProxyPass ^/(.*)$ http://bamboo:8085/$1 However when I type in http: //bamboo in IE, I get 'page cannot be displayed ' message. FF does not return anything at all. I made Wireshark network dump, selected 'follow TCPstream' and it seems like correct page is being retrieved.Why cannot I see it then? I also noticed that I can retrieve http: //bamboo/favicon.ico so I must be very close to the solution.. This is the Wireshark output: GET / HTTP/1.1 Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */* Accept-Language: en-gb User-Agent: Mozilla/4.0 (compatible;

• Referencing movie clips from within an actionscript class

  - by Ant

  Hi all, I have been given the task of adding a scoring system to various flash games. This simply involves taking input, adding functionality such as pausing and replaying and then outputting the score, time left etc. at the end. I've so far successfully edited two games. Both these games used the "actions" code on frames. The latest game I'm trying to do uses an actionscript class which makes it both easier and harder. I'm not very adept at flash at all, but I've worked it out so far. I've added various movie clips that are to be used for displaying the pause screen background, buttons for replaying etc. I've been showing and hiding these using: back._visible = true; //movie clip, instance of back (back.png) I doubt it's best practice, but it's quick and has been working. However, now with the change of coding style to classes, this doesn't seem to work. I kinda understand why, but I'm now unsure how to hide/show these elements. Any help would be greatly appreciated :) I've attached the modified AS. class RivalOrbs extends MovieClip { var infinite_levels, orbs_start, orbs_inc, orbs_per_level, show_timer, _parent, one_time_per_level, speed_start, speed_inc_percent, max_speed, percent_starting_on_wrong_side, colorize, colors, secs_per_level; function RivalOrbs() { super(); mc = this; this.init(); } // End of the function function get_num_orbs() { if (infinite_levels) { return (orbs_start + (level - 1) * orbs_inc); } else if (level > orbs_per_level.length) { return (0); } else { return (orbs_per_level[level - 1]); } // end else if } // End of the function function get_timer_str(secs) { var _loc2 = Math.floor(secs / 60); var _loc1 = secs % 60; return ((_loc2 > 0 ?

• Followup: Python 2.6, 3 abstract base class misunderstanding

  - by Aaron

  I asked a question at Python 2.6, 3 abstract base class misunderstanding. My problem was that python abstract base classes didn't work quite the way I expected them to. There was some discussion in the comments about why I would want to use ABCs at all, and Alex Martelli provided an excellent answer on why my use didn't work and how to accomplish what I wanted. Here I'd like to address why one might want to use ABCs, and show my test code implementation based on Alex's answer. tl;dr: Code after the 16th paragraph. In the discussion on the original post, statements were made along the lines that you don't need ABCs in Python, and that ABCs don't do anything and are therefore not real classes; they're merely interface definitions. An abstract base class is just a tool in your tool box. It's a design tool that's been around for many years, and a programming tool that is explicitly available in many programming languages. It can be implemented manually in languages that don't provide it. An ABC is always a real class, even when it doesn't do anything but define an interface, because specifying the interface is what an ABC does. If that was all an ABC could do, that would be enough reason to have it in your toolbox, but in Python and some other languages they can do more. The basic reason to use an ABC is when you have a number of classes that all do the same thing (have the same interface) but do it differently, and you want to guarantee that that complete interface is implemented in all objects. A user of your classes can rely on the interface being completely implemented in all classes. You can maintain this guarantee manually. Over time you may succeed. Or you might forget something. Before Python had ABCs you could guarantee it semi-manually, by throwing NotImplementedError in all the base class's interface methods; you must implement these methods in derived classes. This is only a partial solution, because you can still instantiate such a base class. A more complete solution is to use ABCs as provided in Python 2.6 and above. Template methods and other wrinkles and patterns are ideas whose implementation can be made easier with full-citizen ABCs. Another idea in the comments was that Python doesn't need ABCs (understood as a class that only defines an interface) because it has multiple inheritance. The implied reference there seems to be Java and its single inheritance. In Java you "get around" single inheritance by inheriting from one or more interfaces. Java uses the word "interface" in two ways. A "Java interface" is a class with method signatures but no implementations. The methods are the interface's "interface" in the more general, non-Java sense of the word. Yes, Python has multiple inheritance, so you don't need Java-like "interfaces" (ABCs) merely to provide sets of interface methods to a class. But that's not the only reason in software development to use ABCs. Most generally, you use an ABC to specify an interface (set of methods) that will likely be implemented differently in different derived classes, yet that all derived classes must have. Additionally, there may be no sensible default implementation for the base class to provide. Finally, even an ABC with almost no interface is still useful. We use something like it when we have multiple except clauses for a try. Many exceptions have exactly the same interface, with only two differences: the exception's string value, and the actual class of the exception. In many exception clauses we use nothing about the exception except its class to decide what to do; catching one type of exception we do one thing, and another except clause catching a different exception does another thing. According to the exception module's doc page, BaseException is not intended to be derived by any user defined exceptions. If ABCs had been a first class Python concept from the beginning, it's easy to imagine BaseException being specified as an ABC. But enough of that. Here's some 2.6 code that demonstrates how to use ABCs, and how to specify a list-like ABC. Examples are run in ipython, which I like much better than the python shell for day to day work; I only wish it was available for python3. Your basic 2.6 ABC: from abc import ABCMeta, abstractmethod class Super(): __metaclass__ = ABCMeta @abstractmethod def method1(self): pass Test it (in ipython, python shell would be similar): In [2]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 Notice the end of the last line, where the TypeError exception tells us that method1 has not been implemented ("abstract methods method1"). That was the method designated as @abstractmethod in the preceding code. Create a subclass that inherits Super, implement method1 in the subclass and you're done. My problem, which caused me to ask the original question, was how to specify an ABC that itself defines a list interface. My naive solution was to make an ABC as above, and in the inheritance parentheses say (list). My assumption was that the class would still be abstract (can't instantiate it), and would be a list. That was wrong; inheriting from list made the class concrete, despite the abstract bits in the class definition. Alex suggested inheriting from collections.MutableSequence, which is abstract (and so doesn't make the class concrete) and list-like. I used collections.Sequence, which is also abstract but has a shorter interface and so was quicker to implement. First, Super derived from Sequence, with nothing extra: from abc import abstractmethod from collections import Sequence class Super(Sequence): pass Test it: In [6]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods __getitem__, __len__ We can't instantiate it. A list-like full-citizen ABC; yea! Again, notice in the last line that TypeError tells us why we can't instantiate it: __getitem__ and __len__ are abstract methods. They come from collections.Sequence. But, I want a bunch of subclasses that all act like immutable lists (which collections.Sequence essentially is), and that have their own implementations of my added interface methods. In particular, I don't want to implement my own list code, Python already did that for me. So first, let's implement the missing Sequence methods, in terms of Python's list type, so that all subclasses act as lists (Sequences). First let's see the signatures of the missing abstract methods: In [12]: help(Sequence.__getitem__) Help on method __getitem__ in module _abcoll: __getitem__(self, index) unbound _abcoll.Sequence method (END) In [14]: help(Sequence.__len__) Help on method __len__ in module _abcoll: __len__(self) unbound _abcoll.Sequence method (END) __getitem__ takes an index, and __len__ takes nothing. And the implementation (so far) is: from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() Test it: In [34]: a = Super() In [35]: a Out[35]: [] In [36]: print a [] In [37]: len(a) Out[37]: 0 In [38]: a[0] --------------------------------------------------------------------------- IndexError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() /home/aaron/projects/test/test.py in __getitem__(self, index) 10 # Abstract method in Sequence, implemented in terms of list. 11 def __getitem__(self, index): ---> 12 return self._list.__getitem__(index) 13 14 # Abstract method in Sequence, implemented in terms of list. IndexError: list index out of range Just like a list. It's not abstract (for the moment) because we implemented both of Sequence's abstract methods. Now I want to add my bit of interface, which will be abstract in Super and therefore required to implement in any subclasses. And we'll cut to the chase and add subclasses that inherit from our ABC Super. from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() @abstractmethod def method1(): pass class Sub0(Super): pass class Sub1(Super): def __init__(self): self._list = [1, 2, 3] def method1(self): return [x**2 for x in self._list] def method2(self): return [x/2.0 for x in self._list] class Sub2(Super): def __init__(self): self._list = [10, 20, 30, 40] def method1(self): return [x+2 for x in self._list] We've added a new abstract method to Super, method1. This makes Super abstract again. A new class Sub0 which inherits from Super but does not implement method1, so it's also an ABC. Two new classes Sub1 and Sub2, which both inherit from Super. They both implement method1 from Super, so they're not abstract. Both implementations of method1 are different. Sub1 and Sub2 also both initialize themselves differently; in real life they might initialize themselves wildly differently. So you have two subclasses which both "is a" Super (they both implement Super's required interface) although their implementations are different. Also remember that Super, although an ABC, provides four non-abstract methods. So Super provides two things to subclasses: an implementation of collections.Sequence, and an additional abstract interface (the one abstract method) that subclasses must implement. Also, class Sub1 implements an additional method, method2, which is not part of Super's interface. Sub1 "is a" Super, but it also has additional capabilities. Test it: In [52]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 In [53]: a = Sub0() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Sub0 with abstract methods method1 In [54]: a = Sub1() In [55]: a Out[55]: [1, 2, 3] In [56]: b = Sub2() In [57]: b Out[57]: [10, 20, 30, 40] In [58]: print a, b [1, 2, 3] [10, 20, 30, 40] In [59]: a, b Out[59]: ([1, 2, 3], [10, 20, 30, 40]) In [60]: a.method1() Out[60]: [1, 4, 9] In [61]: b.method1() Out[61]: [12, 22, 32, 42] In [62]: a.method2() Out[62]: [0.5, 1.0, 1.5] [63]: a[:2] Out[63]: [1, 2] In [64]: a[0] = 5 --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: 'Sub1' object does not support item assignment Super and Sub0 are abstract and can't be instantiated (lines 52 and 53). Sub1 and Sub2 are concrete and have an immutable Sequence interface (54 through 59). Sub1 and Sub2 are instantiated differently, and their method1 implementations are different (60, 61). Sub1 includes an additional method2, beyond what's required by Super (62). Any concrete Super acts like a list/Sequence (63). A collections.Sequence is immutable (64). Finally, a wart: In [65]: a._list Out[65]: [1, 2, 3] In [66]: a._list = [] In [67]: a Out[67]: [] Super._list is spelled with a single underscore. Double underscore would have protected it from this last bit, but would have broken the implementation of methods in subclasses. Not sure why; I think because double underscore is private, and private means private. So ultimately this whole scheme relies on a gentleman's agreement not to reach in and muck with Super._list directly, as in line 65 above. Would love to know if there's a safer way to do that.

exist for the emailaddress dont update data else create a user and update its profilexml from data fecthed from gedcom. for this i think i need some soln by which i can do only one roundtrip to database and can update all user's xml. or i can execute one sp to get userid from all users where i'll check if user exist then return userid else insert basic data and return inserted userid then for every user make xml from data and update it. please provide be suggestion what is best practice to do this kind of development. if need any more details please write me

• racket scheme get-argb-pixels

  - by Giles Roberts

  I have a 32 by 32 pixel png file. I'm trying to read the values within it using get-argb-pixels. My code is as follows: #lang racket/gui (require racket/gui/base) (define floor (make-object bitmap% "C:\\floortile.png")) (define pixels (make-bytes (* 32 32 4))) (send floor get-argb-pixels 0 0 32 32 pixels) After executing the code I was expecting a series of 8 bit values to be contained within pixels. Examining pixels gives me the following output: > pixels

• NSXMLParser and Geonames

  - by Xcoder

  I'm trying to parse a call from Geonames with NSXMLParser in the iPhone SDK. I've used this before but for some reason I'm getting an empty dictionary back even though I get results back in a web browser. Can someone please point out what I may be doing wrong. Below is the code I'm using and the results that comes back pasting it in a browser. Thanks in advance #pragma mark - #pragma mark - Parcer Services -(void)beginLoadingFeed{ //[self startLoadingWithMessage:@"Loading Results...."]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(loadFeed) object:nil]; [operationQueue addOperation:operation]; [operation release]; } - (void)loadFeed{ NSString *path = [NSString stringWithFormat:@"http://ws.geonames.org/postalCodeSearch?placename=%@&long&maxRows=20",self.location]; [Logger log:@"Geonames Query: %@",path]; [self parseXMLFileAtURL:path]; [self performSelectorOnMainThread:@selector(didfinishedLoadingFeed) withObject:nil waitUntilDone:YES]; } -(void)didfinishedLoadingFeed{ } - (void)parserDidStartDocument:(NSXMLParser *)parser{ [Logger log:@"found file and started parsing"]; } //Called when the parser runs into an open tag (<tag>) - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict { if ([elementName isEqualToString:@"code"]) { currentResult = [NSMutableDictionary dictionary]; } else { currentElement = [elementName copy]; } } //This is just to resolve random HTML entities - (NSData *)parser:(NSXMLParser *)parser resolveExternalEntityName:(NSString *)entityName systemID:(NSString *)systemID { return [entityName dataUsingEncoding:NSASCIIStringEncoding]; } - (void)parseXMLFileAtURL:(NSString *)URL{ self.results = [[[NSMutableArray alloc] init] autorelease]; NSURL *xmlURL = [NSURL URLWithString:URL]; NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; [parser setDelegate:self]; [parser parse]; [parser autorelease]; } - (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { NSString * errorString = [NSString stringWithFormat:@"Unable to connect to web site (Error code %i )", [parseError code]]; [Logger log:@"error parsing : %@", errorString]; [self stopLoadingView]; [self showMessage:@"Error loading content" withTitle:@"Error Loading"]; } /*** Called when the parser runs into a close tag (</tag>).

• Sensible Way to Pass Web Data in XML to a SQL Server Database

  - by Emtucifor

  After exploring several different ways to pass web data to a database for update purposes, I'm wondering if XML might be a good strategy. The database is currently SQL 2000. In a few months it will move to SQL 2005 and I will be able to change things if needed, but I need a SQL 2000 solution now. First of all, the database in question uses the EAV model. I know that this kind of database is generally highly frowned on, so for the purposes of this question, please just accept that this is not going to change. The current update method has the web server inserting values (that have all been converted first to their correct underlying types, then to sql_variant) to a temp table. A stored procedure is then run which expects the temp table to exist and it takes care of updating, inserting, or deleting things as needed. So far, only a single element has needed to be updated at a time. But now, there is a requirement to be able to edit multiple elements at once, and also to support hierarchical elements, each of which can have its own list of attributes. Here's some example XML I hand-typed to demonstrate what I'm thinking of. Note that in this database the Entity is Element and an ID of 0 signifies "create" aka an insert of a new item. <Elements> <Element ID="1234"> <Attr ID="221">Value</Attr> <Attr ID="225">287</Attr> <Attr ID="234"> <Element ID="99825"> <Attr ID="7">Value1</Attr> <Attr ID="8">Value2</Attr> <Attr ID="9" Action="delete" /> </Element> <Element ID="99826" Action="delete" /> <Element ID="0" Type="24"> <Attr ID="7">Value4</Attr> <Attr ID="8">Value5</Attr> <Attr ID="9">Value6</Attr> </Element> <Element ID="0" Type="24"> <Attr ID="7">Value7</Attr> <Attr ID="8">Value8</Attr> <Attr ID="9">Value9</Attr> </Element> </Attr> <Rel ID="3827" Action="delete" /> <Rel ID="2284" Role="parent"> <Element ID="3827" /> <Element ID="3829" /> <Attr ID="665">1</Attr> </Rel> <Rel ID="0" Type="23" Role="child"> <Element ID="3830" /> <Attr ID="67" </Rel> </Element> <Element ID="0" Type="87"> <Attr ID="221">Value</Attr> <Attr ID="225">569</Attr> <Attr ID="234"> <Element ID="0" Type="24"> <Attr ID="7">Value10</Attr> <Attr ID="8">Value11</Attr> <Attr ID="9">Value12</Attr> </Element> </Attr> </Element> <Element ID="1235" Action="delete" /> </Elements> Some Attributes are straight value types, such as AttrID 221. But AttrID 234 is a special "multi-value" type that can have a list of elements underneath it, and each one can have one or more values. Types only need to be presented when a new item is created, since the ElementID fully implies the type if it already exists. I'll probably support only passing in changed items (as detected by javascript). And there may be an Action="Delete" on Attr elements as well, since NULLs are treated as "unselected"--sometimes it's very important to know if a Yes/No question has intentionally been answered No or if no one's bothered to say Yes yet. There is also a different kind of data, a Relationship. At this time, those are updated through individual AJAX calls as things are edited in the UI, but I'd like to include those so that changes to relationships can be canceled (right now, once you change it, it's done). So those are really elements, too, but they are called Rel instead of Element. Relationships are implemented as ElementID1 and ElementID2, so the RelID 2284 in the XML above is in the database as: ElementID 2284 ElementID1 1234 ElementID2 3827 Having multiple children in one relationship isn't currently supported, but it would be nice later. Does this strategy and the example XML make sense? Is there a more sensible way? I'm just looking for some broad critique to help save me from going down a bad path. Any aspect that you'd like to comment on would be helpful. The web language happens to be Classic ASP, but that could change to ASP.Net at some point. A persistence engine like Linq or nHibernate is probably not acceptable right now--I just want to get this already working application enhanced without a huge amount of development time. I'll choose the answer that shows experience and has a balance of good warnings about what not to do, confirmations of what I'm planning to do, and recommendations about something else to do. I'll make it as objective as possible. P.S. I'd like to handle unicode characters as well as very long strings (10k +). UPDATE I have had this working for some time and I used the ADO Recordset Save-To-Stream trick to make creating the XML really easy. The result seems to be fairly fast, though if speed ever becomes a problem I may revisit this. In the meantime, my code works to handle any number of elements and attributes on the page at once, including updating, deleting, and creating new items all in one go. I settled on a scheme like so for all my elements: Existing data elements Example: input name e12345_a678 (element 12345, attribute 678), the input value is the value of the attribute. New elements Javascript copies a hidden template of the set of HTML elements needed for the type into the correct location on the page, increments a counter to get a new ID for this item, and prepends the number to the names of the form items. var newid = 0; function metadataAdd(reference, nameid, value) { var t = document.createElement('input'); t.setAttribute('name', nameid); t.setAttribute('id', nameid); t.setAttribute('type', 'hidden'); t.setAttribute('value', value); reference.appendChild(t); } function multiAdd(target, parentelementid, attrid, elementtypeid) { var proto = document.getElementById('a' + attrid + '_proto'); var instance = document.createElement('p'); target.parentNode.parentNode.insertBefore(instance, target.parentNode); var thisid = ++newid; instance.innerHTML = proto.innerHTML.replace(/{prefix}/g, 'n' + thisid + '_'); instance.id = 'n' + thisid; instance.className += ' new'; metadataAdd(instance, 'n' + thisid + '_p', parentelementid); metadataAdd(instance, 'n' + thisid + '_c', attrid); metadataAdd(instance, 'n' + thisid + '_t', elementtypeid); return false; } Example: Template input name _a678 becomes n1_a678 (a new element, the first one on the page, attribute 678). all attributes of this new element are tagged with the same prefix of n1. The next new item will be n2, and so on. Some hidden form inputs are created: n1_t, value is the elementtype of the element to be created n1_p, value is the parent id of the element (if it is a relationship) n1_c, value is the child id of the element (if it is a relationship) Deleting elements A hidden input is created in the form e12345_t with value set to 0. The existing controls displaying that attribute's values are disabled so they are not included in the form post. So "set type to 0" is treated as delete. With this scheme, every item on the page has a unique name and can be distinguished properly, and every action can be represented properly. When the form is posted, here's a sample of building one of the two recordsets used (classic ASP code): Set Data = Server.CreateObject("ADODB.Recordset") Data.Fields.Append "ElementID", adInteger, 4, adFldKeyColumn Data.Fields.Append "AttrID", adInteger, 4, adFldKeyColumn Data.Fields.Append "Value", adLongVarWChar, 2147483647, adFldIsNullable Or adFldMayBeNull Data.CursorLocation = adUseClient Data.CursorType = adOpenDynamic Data.Open This is the recordset for values, the other is for the elements themselves. I step through the posted form and for the element recordset use a Scripting.Dictionary populated with instances of a custom Class that has the properties I need, so that I can add the values piecemeal, since they don't always come in order. New elements are added as negative to distinguish them from regular elements (rather than requiring a separate column to indicate if it is new or addresses an existing element). I use regular expression to tear apart the form keys: "^(e|n)([0-9]{1,10})_(a|p|t|c)([0-9]{0,10})$" Then, adding an attribute looks like this. Data.AddNew ElementID.Value = DataID AttrID.Value = Integerize(Matches(0).SubMatches(3)) AttrValue.Value = Request.Form(Key) Data.Update ElementID, AttrID, and AttrValue are references to the fields of the recordset. This method is hugely faster than using Data.Fields("ElementID").Value each time. I loop through the Dictionary of element updates and ignore any that don't have all the proper information, adding the good ones to the recordset. Then I call my data-updating stored procedure like so: Set Cmd = Server.CreateObject("ADODB.Command") With Cmd Set .ActiveConnection = MyDBConn .CommandType = adCmdStoredProc .CommandText = "DataPost" .Prepared = False .Parameters.Append .CreateParameter("@ElementMetadata", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Element)) .Parameters.Append .CreateParameter("@ElementData", adLongVarWChar, adParamInput, 2147483647, XMLFromRecordset(Data)) End With Result.Open Cmd ' previously created recordset object with options set Here's the function that does the xml conversion: Private Function XMLFromRecordset(Recordset) Dim Stream Set Stream = Server.CreateObject("ADODB.Stream") Stream.Open Recordset.Save Stream, adPersistXML Stream.Position = 0 XMLFromRecordset = Stream.ReadText End Function Just in case the web page needs to know, the SP returns a recordset of any new elements, showing their page value and their created value (so I can see that n1 is now e12346 for example). Here are some key snippets from the stored procedure. Note this is SQL 2000 for now, though I'll be able to switch to 2005 soon: CREATE PROCEDURE [dbo].[DataPost] @ElementMetaData ntext, @ElementData ntext AS DECLARE @hdoc int --- snip --- EXEC sp_xml_preparedocument @hdoc OUTPUT, @ElementMetaData, '<xml xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema" />' INSERT #ElementMetadata (ElementID, ElementTypeID, ElementID1, ElementID2) SELECT * FROM OPENXML(@hdoc, '/xml/rs:data/rs:insert/z:row', 0) WITH ( ElementID int, ElementTypeID int, ElementID1 int, ElementID2 int ) ORDER BY ElementID -- orders negative items (new elements) first so they begin counting at 1 for later ID calculation EXEC sp_xml_removedocument @hdoc --- snip --- UPDATE E SET E.ElementTypeID = M.ElementTypeID FROM Element E INNER JOIN #ElementMetadata M ON E.ElementID = M.ElementID WHERE E.ElementID >= 1 AND M.ElementTypeID >= 1 The following query does the correlation of the negative new element ids to the newly inserted ones: UPDATE #ElementMetadata -- Correlate the new ElementIDs with the input rows SET NewElementID = Scope_Identity() - @@RowCount + DataID WHERE ElementID < 0 Other set-based queries do all the other work of validating that the attributes are allowed, are the correct data type, and inserting, updating, and deleting elements and attributes. I hope this brief run-down is useful to others some day! Converting ADO Recordsets to an XML stream was a huge winner for me as it saved all sorts of time and had a namespace and schema already defined that made the results come out correctly. Using a flatter XML format with 2 inputs was also much easier than sticking to some ideal about having everything in a single XML stream.

Note this is SQL 2000 for now, though I'll be able to switch to 2005 soon: CREATE PROCEDURE [dbo].[DataPost] @ElementMetaData ntext, @ElementData ntext AS DECLARE @hdoc int --- snip --- EXEC sp_xml_preparedocument @hdoc OUTPUT, @ElementMetaData, '<xml xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema" />' INSERT #ElementMetadata (ElementID, ElementTypeID, ElementID1, ElementID2) SELECT * FROM OPENXML(@hdoc, '/xml/rs:data/rs:insert/z:row', 0) WITH ( ElementID int, ElementTypeID int, ElementID1 int, ElementID2 int ) ORDER BY ElementID -- orders negative items (new elements) first so they begin counting at 1 for later ID calculation EXEC sp_xml_removedocument @hdoc --- snip --- UPDATE E SET E.ElementTypeID = M.ElementTypeID FROM Element E INNER JOIN #ElementMetadata M ON E.ElementID = M.ElementID WHERE E.ElementID >= 1 AND M.ElementTypeID >= 1 The following query does the correlation of the negative new element ids to the newly inserted ones: UPDATE #ElementMetadata -- Correlate the new ElementIDs with the input rows SET NewElementID = Scope_Identity() - @@RowCount + DataID WHERE ElementID < 0 Other set-based queries do all the other work of validating that the attributes are allowed, are the correct data type, and inserting, updating, and deleting elements and attributes. I hope this brief run-down is useful to others some day! Converting ADO Recordsets to an XML stream was a huge winner for me as it saved all sorts of time and had a namespace and schema already defined that made the results come out correctly. Using a flatter XML format with 2 inputs was also much easier than sticking to some ideal about having everything in a single XML stream.

• DropDownList Value not changing with UpdatePanel and ModalPopupExtender

  - by Richard

  Greetings, I have an asp.net webpage with an modalpopupextender inside of an updatepanel. When I click Ok on the popup, I can get the textbox values from the popup just fine, but the DropDownLists have the old/default value, not the new value I have selected for them. All the controls on the popup are set to enableviewstate = true, and autopostback = false (I just want to make the trip to the server when I click the ok button, not every time I change the value of the popups). Here is the relevant code. ========================== Client Side <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:Panel ID="EditIssuePanel" runat="server" CssClass="modalPopup" Style="display:block;" > <table style="width:500px;"> <tr style="height:50px;"> <td colspan="2" align="center"> <asp:Label ID="lblEditIssueHeader" runat="server" Text="Edit Issue"></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblIssueName" runat="server" Text="Name:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtName" runat="server" Width="250px" MaxLength="50"></asp:TextBox> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblDescription" runat="server" Text="Description:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtDescription" runat="server" Width="250px" MaxLength="1000"></asp:TextBox> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblType" runat="server" Text="Type:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlType" runat="server"> <asp:ListItem Selected="True" Value="B">Bug</asp:ListItem> <asp:ListItem Value="R">Request</asp:ListItem> <asp:ListItem Value="O">Other</asp:ListItem> </asp:DropDownList> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblStatus" runat="server" Text="Status:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlStatus" runat="server"> <asp:ListItem Selected="True" Value="L">Logged</asp:ListItem> <asp:ListItem Value="I">In Process</asp:ListItem> <asp:ListItem Value="C">Complete</asp:ListItem> </asp:DropDownList> &nbsp; </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblPriority" runat="server" Text="Priority:"></asp:Label> </td> <td class="datacolumn"> <asp:DropDownList ID="ddlPriority" runat="server" EnableViewState="true" AutoPostBack="false"> <asp:ListItem Selected="True" Value="L">Low</asp:ListItem> <asp:ListItem Value="M">Medium</asp:ListItem> <asp:ListItem Value="H">High</asp:ListItem> </asp:DropDownList> &nbsp;</td> </tr> <tr style="height:30px"> <td class="labelscolumn">Logger</td> <td class="datacolumn"> <asp:Label ID="lblEnteredByClientUserID" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn"> <asp:Label ID="lblDateResolutionRequested" runat="server" Text="Requested Complete Date:"></asp:Label> </td> <td class="datacolumn"> <igsch:WebDateChooser ID="wdcRequestCompleteDate" runat="server"> </igsch:WebDateChooser> &nbsp;</td> </tr> <tr style="height:30px"> <td class="labelscolumn">Logged Date</td> <td class="datacolumn"> <asp:Label ID="lblLoggedDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px"> <td class="labelscolumn">In Process Date</td> <td class="datacolumn"> <asp:Label ID="lblInProcessDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px"> <td class="labelscolumn">Resolved Date</td> <td class="datacolumn"> <asp:Label ID="lblResolvedDate" runat="server" Text=""></asp:Label> </td> </tr> <tr style="height:30px;"> <td class="labelscolumn" valign="top"> <asp:Label ID="lblEmailCCList" runat="server" Text="Email CC:"></asp:Label> </td> <td class="datacolumn"> <asp:TextBox ID="txtEmailCCList" runat="server" MaxLength="2000" Rows="0" TextMode="MultiLine" Height="83px" Width="250px"></asp:TextBox> &nbsp;</td> </tr> <tr> <td> <asp:Label ID="lblIssueID" runat="server" Text="" Visible="false"></asp:Label> <asp:Label ID="lblClientID" runat="server" Text="" Visible="false"></asp:Label> </td> <td align="right"> <asp:Button ID="btnEditOk" runat="server" Text="Ok" onclick="btnEditOk_Click"/>&nbsp;&nbsp; <asp:Button ID="btnEditCancel" runat="server" Text="Cancel" onclick="btnEditCancel_Click" />&nbsp;&nbsp;&nbsp;&nbsp; </td> </tr> </table> </asp:Panel> . . .

• trouble running smooth animation in thread only when using key listener

  - by heysuse renard

  first time using a forum for coding help so sorry if i post this all wrong. i have more than a few classes i don't think screenManger or core holds the problem but i included them just incase. i got most of this code working through a set of tutorials. but a certain point started trying to do more on my own. i want to play the animation only when i'm moving my sprite. in my KeyTest class i am using threads to run the animation it used to work (poorly) but now not at all pluss it really gunks up my computer. i think it's because of the thread. im new to threads so i'm not to sure if i should even be using one in this situation or if its dangerous for my computer. the animation worked smoothly when i had the sprite bouce around the screen forever. the animation loop played with out stopping. i think the main problem is between the animationThread, Sprite, and keyTest classes, but itcould be more indepth. if someone could point me in the right direction for making the animation run smoothly when i push down a key and stop runing when i let off it would be greatly apriciated. i already looked at this Java a moving animation (sprite) obviously we were doing the same tutorial. but i feel my problem is slightly different. p.s. sorry for the typos. import java.awt.*;

• Problems Allocating Objects of Derived Class Where Base Class has Abstract Virtual Functions

  - by user1743901

  I am trying to get this Zombie/Human agent based simulation running, but I am having problems with these derived classes (Human and Zombie) who have parent class "Creature". I have 3 virtual functions declared in "Creature" and all three of these are re-declared AND DEFINED in both "Human" and "Zombie".

• Xml failing to deserialise

  - by Carnotaurus

  I call a method to get my pages [see GetPages(String xmlFullFilePath)]. The FromXElement method is supposed to deserialise the LitePropertyData elements to strongly type LitePropertyData objects. Instead it fails on the following line: return (T)xmlSerializer.Deserialize(memoryStream); and gives the following error: <LitePropertyData xmlns=''> was not expected. What am I doing wrong? I have included the methods that I call and the xml data: public static T FromXElement<T>(this XElement xElement) { using (var memoryStream = new MemoryStream(Encoding.ASCII.GetBytes(xElement.ToString()))) { var xmlSerializer = new XmlSerializer(typeof(T)); return (T)xmlSerializer.Deserialize(memoryStream); } } public static List<LitePageData> GetPages(String xmlFullFilePath) { XDocument document = XDocument.Load(xmlFullFilePath); List<LitePageData> results = (from record in document.Descendants("row") select new LitePageData { Guid = IsValid(record, "Guid") ? record.Element("Guid").Value : null, ParentID = IsValid(record, "ParentID") ? Convert.ToInt32(record.Element("ParentID").Value) : (Int32?)null, Created = Convert.ToDateTime(record.Element("Created").Value), Changed = Convert.ToDateTime(record.Element("Changed").Value), Name = record.Element("Name").Value, ID = Convert.ToInt32(record.Element("ID").Value), LitePageTypeID = IsValid(record, "ParentID") ? Convert.ToInt32(record.Element("ParentID").Value) : (Int32?)null, Html = record.Element("Html").Value, FriendlyName = record.Element("FriendlyName").Value, Properties = record.Element("Properties") != null ? record.Element("Properties").Element("LitePropertyData").FromXElement<List<LitePropertyData>>() : new List<LitePropertyData>() }).ToList(); return results; } Here is the xml: <?xml version="1.0" encoding="utf-8"?> <root> <rows> <row> <ID>1</ID> <ImageUrl></ImageUrl> <Html>Home page</Html> <Created>01-01-2012</Created> <Changed>01-01-2012</Changed> <Name>Home page</Name> <FriendlyName>home-page</FriendlyName> </row> <row xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Guid>edeaf468-f490-4271-bf4d-be145bc6a1fd</Guid> <ID>8</ID> <Name>Unused</Name> <ParentID>1</ParentID> <Created>2006-03-25T10:57:17</Created> <Changed>2012-07-17T12:24:30.0984747+01:00</Changed> <ChangedBy /> <LitePageTypeID xsi:nil="true" /> <Html> What is the purpose of this option?

Nevertheless, let me explain my issues with Bobby and Cynthia: First, certain W3C standards for designing web documents are often too strict and unworkable. For instance, in some versions W3C standards for HTML, certain tags should not include a particular attribute, whereas in others they are requisite if the document is to be ???well-formed???. The standard that a designer chooses is determined usually by the requirements specification document. This specifies which browsers and versions of those browsers that the web page is expected to correctly display. Forcing a hypertext document to conform strictly to a specific W3C standard for HTML is often no simple task. In the worst case, it cannot conform without losing some aesthetics or accessibility functionality. Second, the case of HTML documents is not an isolated case. Standards for XML, XSL, JavaScript, VBScript, are analogous. Therefore, you might imagine the problems when you begin to combine these languages and formats in an HTML document. Third, there is always more than one way to skin a cat. For example, Bobby and Cynthia may flag those IMG tags that do not contain a TITLE attribute. There might be good reason that a web developer chooses not to include the title attribute. The title attribute has a limited numbers of characters and does not support carriage returns. This is a major defect in the design of this tag. In fact, before the TITLE attribute was supported, there was the ALT attribute. Most browsers support both, yet they both perform a similar function. However, both attributes share the same deficiencies. In practice, there are instances where neither attribute would be used. Instead, for example, the developer would write some JavaScript or VBScript to circumvent these deficiencies. The concern is that Bobby and Cynthia would not notice this because it does not ???understand??? what the JavaScript does. </Html> <FriendlyName>unused</FriendlyName> <IsDeleted>false</IsDeleted> <Properties> <LitePropertyData> <Description>Image for the page</Description> <DisplayEditUI>true</DisplayEditUI> <OwnerTab>1</OwnerTab> <DisplayName>Image Url</DisplayName> <FieldOrder>1</FieldOrder> <IsRequired>false</IsRequired> <Name>ImageUrl</Name> <IsModified>false</IsModified> <ParentPageID>3</ParentPageID> <Type>String</Type> <Value xsi:type="xsd:string">smarter.jpg</Value> </LitePropertyData> <LitePropertyData> <Description>WebItemApplicationEnum</Description> <DisplayEditUI>true</DisplayEditUI> <OwnerTab>1</OwnerTab> <DisplayName>WebItemApplicationEnum</DisplayName> <FieldOrder>1</FieldOrder> <IsRequired>false</IsRequired> <Name>WebItemApplicationEnum</Name> <IsModified>false</IsModified> <ParentPageID>3</ParentPageID> <Type>Number</Type> <Value xsi:type="xsd:string">1</Value> </LitePropertyData> </Properties> <Seo> <Author>Phil Carney</Author> <Classification /> <Copyright>Carnotaurus</Copyright> <Description> What is the purpose of this option?

• Internet Explorer 8 Standards Mode Results In Broken Blank Page

  - by Agent_9191

  I'm running into a weird issue that I'm struggling to figure out what's causing the page to break. I have an internal website that's still under development (thus no link to the page) that works great in Firefox and Internet Explorer 8 in IE 7 Standards mode. But when I force it to IE 8 Standards mode the page will only display the title text in the browser tab and an otherwise completely blank page. It seems so broken that the blank page doesn't even have a context menu. The page generally looks like this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="IE=8" http-equiv="X-UA-Compatible" /> <title>Page Title</title> <link rel="shortcut icon" href="/Images/favicon.ico" type="image/x-icon" /> <link href="/Style/main.less" rel="stylesheet" type="text/css" /> </head> <body> ... </body> </html> You may notice the .less extension for the stylesheet. This is an ASP.NET MVC application and I'm making use of DotLess. I have the HttpHandler hooked up for it in the web.config. Of course there's some additional info on the page, but (in theory) it shouldn't be causing this issue. I've run the CSS and the HTML through the W3C validators and both have come back as completely valid. I'm trying the arduous task of removing/re-adding elements until it displays, but any insight into what could cause this would help. EDIT: it appears to be something related to the DotLess stylesheet. The resulting CSS is valid according to the W3C CSS validator. EDIT 2: Digging further, and making use of IE's Developer Tools to control the styles, it appears that IE is reading a single statement twice even though it only occurs once in the output.

I don't know what's causing that as it's only appearing once in the output stream. Here's an image of it too: EDIT 3: It appears that even though it duplicates that particular selector, if I change the font-size to a whole number like 61% instead of the current 60.95% (that specific to defaultly match the existing desktop app as closely as possible) it works fine. So something specific to IE duplicating that selector block and the font-size being a percentage specific to two decimal places appears to kill IE8 Standards mode completely.

Constructive feedback and criticism greatly welcome (...and needed)!

• Reading data in from file

  - by user667430

  Hi Here is link if you want to download application: Simple banking app Text file with data to read I am trying to create a simple banking application that reads in data from a text file. So far i have managed to read in all the customers which there are 20 of them. However when reading in the accounts and transactions stuff it only reads in 20 but there is alot more in the text file. Here is what i have so far. I think it has something to do with the nested for loop in the getNextCustomer method. using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Data;
