• asp.net dynamic sitemap with querystring? Session variable seems like overkill.

  - by Mike

  Hi, I'm using ASP.NET WebForms. I'm using the standard sitemap provider. Home User Account Entry Going to the home page should have a user selection screen. Clicking on a user should list out the user's accounts with options to edit, delete, add accounts. Selecting an account should list out all the user's account's entries with options to edit delete and add entries. How do you normally pass this information between pages? I could use the query string, but then, the sitemap doesn't work. The sitemap only has the exact page without the query string and therefore loses the information. /User/Account/List.aspx?User=123 /User/Account/Entry/List.aspx?User=123&Account=322 I could use a session variable, but this seems overkill. Thoughts and suggestions very appreciated. Thanks!

• WCF via Windows Service - Authinticating Clients

  - by Sean

  I am a WCF / Security Newb. I have created a WCF service which is hosted via a windows service. The WCF service grabs data from a 3rd party data source that is secured via windows authentication. I need to either: Pass the client's priveleges through the windows service, through the WCF service and into the 3rd party data source, or... Limit who can call the windows service / wcf service to members of a particular AD group. Any suggestions on how I can do either of these tasks?

• Is it possible for parent window to notice if child window has been closed ???

  - by masato-san

  I have parent window (opener) and child (popup) ---------- -------------- | | | | | parent | -----> opens popup | child | | | | | ----------- -------------- Let's say, in parent page, I have js function hello() In order for child to call parent's hello() when the child window is closed and also pass an argument, I can do, window.close(); window.opener.hello(someArgument); This will close the window and also call parent's hello(); But what if I don't want to have the code window.opener.hello() in child page? I mean I want the code to be in parent page only One thing I can think of is: Somewhat parent knows when the child is closed (event listenr??? not sure in js) But in such case how to receive the argument? (i.e. some data back from the child)

• Silverlight chart with behavior/bitmap image tooltip passthrough

  - by isitdanny

  I have a chart showing bound data as tooltips and it works well. I have added a magnifier(set of behaviors class) that captures a bitmap image at two times scale that shows in a circular area over the hover spot. The tooltip does not display. I have tried a custom tooltip service but cannot bind it to the behaviors. I added the tooltip to the behavior class and got a tooltip and data but could not move it with the magnifier. It just sits in the middle and laughs. I added a usercontrol "tooltip"-same issues, could not hook it to the magnifier behavior. I know I can probably build a popup, but really wanted to just pass through the bitmap layer with the tootip. Any ideas would be greatly appreciated. Danny

• Repeater itemdatabound event value type and reference type

  - by Sune

  Im trying to bind a list with datetime objects to my repeater. if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) { DateTime actualDate = e.Item.DataItem as DateTime; } When I want access the itemdatabound event on the repeater Then I get an errormessage which says that DateTime is a valuetype and not a reference type. My solution is that a wrap the datetime in a custom object (reference type) and pass that to the repeater datasource instead of the datetime. But Im wondering if there are other solutions where the repeater takes valuetypes (DateTime objects)........

• JSP tag lifecycle

  - by mkoryak

  i just introduced a bug into my code because i seem to have misunderstood the jsp tag lifecycle. The tag worked like this before the bug: i pass the tag some collection as an attribute, and it displays it as a table. The collection was passed into the JSP from the controller. after the bug: a removed the attribute which set the collection. instead, in the tag i check if the collection is null, and then grab it by name from the request (using a naming convention). the thing that i didnt expect: after the collection was initially set in the tag, it would never become null on subsequent executions! it was still defined as an non-requred attribute in the TLD. I expected the tag to not hold on to previous values between executions.

• unittest tests reuse for family of classes

  - by zaharpopov

  I have problem organizing my unittest based class test for family of tests. For example assume I implement a "dictionary" interface, and have 5 different implementations want to testing. I do write one test class that tests a dictionary interface. But how can I nicely reuse it to test my all classes? So far I do ugly: DictType = hashtable.HashDict In top of file and then use DictType in test class. To test another class I manually change the DictType to something else. How can do this otherwise? Can't pass arguments to unittest classes so is there a nicer way?

• How to provide custom connection string for Logging Application Block instead of using the one in .c

  - by Rory

  I'm modifying an existing winforms application to use the Logging Application Block. For historical reasons this app gets its main database connection string from the registry, and I'd like the Logging Application Block to use the same details for logging to the database. How can I do this? The approaches i can think of are: 1) Create a new TraceListener and implement the same sort of functionality as in FormattedDatabaseTraceListener. If I take this approach, should I inherit from CustomTraceListener, and if so how do I pass an attribute of the formatter to use? 2) Create a new ConfigurationSource that provides different details when asked for the database connection. All other requests would be passed through to a FileConfigurationSource, but when asked for the database connection details the object would read the appropriate bits from the registry instead. but it's not obvious which is more appropriate, or how to go about doing it. Any suggestions? I'm using EntLib 3.1. thanks, -Rory

• write client ip in iis 7.0 log over firewalls

  - by Guy Bertental

  Hi, I a solution for IIS 7.0 which runs on windows server 2008 64bit to write my clients IP to IIS logs while the server is behind firewalls and proxies (Pass X-Forwarded-For header value). I've tried to install the an ISAPI Filter written by Joe Pruitt. it works great on Windows Server 2003 32bit IIS 6.0, but seems to do nothing at all on windows server 2008 64bit IIS 7.0. Did anyone try this ISAPI filter on this version of OS? or have another solution? link to the Joe Pruitt's (from F5) ISAPI filter: http://devcentral.f5.com/weblogs/Joe/archive/2009/08/19/x_forwarded_for_log_filter_for_windows_servers.aspx best regards, guy bertental

• add methods in subclasses within the super class constructor

  - by deamon

  I want to add methods (more specifically: method aliases) automatically to Python subclasses. If the subclass defines a method named 'get' I want to add a method alias 'GET' to the dictionary of the subclass. To not repeat myself I'd like to define this modifation routine in the base class. But if I check in the base class init method, there is no such method, since it is defined in the subclass. It will become more clear with some source code: class Base: def __init__(self): if hasattr(self, "get"): setattr(self, "GET", self.get) class Sub(Base): def get(): pass print(dir(Sub)) Output: ['__doc__', '__init__', '__module__', 'get'] It should also contain 'GET'. Is there a way to do it within the base class?

• javascript eval backslash in window NT path problem

  - by Hammad Tariq

  I am experiencing a classic JS case (in my opinion) but after a lot of googling, still not able to find a solution. Backslash is considered as a escape character in JS but what you need when you need to pass windows path from the JS and print it? I am using eval because my java applet is executing the code and placing bits when it has a string to evaluate. That's why eval is necessary, however I have made an example which is below: <div id="mainTabs"></div> <script> var s = "document.getElementById('mainTabs').innerHTML='\\C\ganye\file.doc'"; eval(s); </script> I tried double backslashes, not working, if anyone could help me get around this with as less hassle as possible, I will feel grateful.

• Viewing large text file in a browser

  - by MeLight

  Hi, I need to write a text file viewer (not the directory tree, but the actual file contents) for use in a browser. It will be used to view large files. I want to give the user the ability to actually ummm, browse the file, ie prev page & next page buttons, while each page will show only a portion of the file. Two question: Is there anyway to pass the file descriptor through POST (or something) so that on each page I can keep reading from an already open file, and not starting all over again (again - huge files) Is there a way to read the file backwards? Will be very useful for browsing back in a file. Any other implementation ideas are very welcome. Thanks

• stringtemplate .net dynamic object

  - by Mark Milford

  Hi I am using string template to render some content, but the content may be variable so not sure how to pass it in (using .net / c#) Basic idea is I have a List which need to end up as parameters, e.g. List<KeyValuePair<string, object>> ret = new List<KeyValuePair<string, object>>(); ret.Add(new KeyValuePair<string, object>("elem1", true)); ret.Add(new KeyValuePair(string, object>("elem2", false)); Now I want these to show up in string template as: $item.elem1$ $item.elem2$ I can get them to be $elem1$ or $elem2$ but i need them inside of a structure. So I in effect need to convince the string template setAttribute that I'm passing in an object with properties elem1 and elem2 when in fact I have a List of KeyValuePairs. Thanks

• What's the best way to resolve a filepath?

  - by BillyONeal

  Hello everyone :) I've got a series of filepaths that look something like this: C:\Windows\System32\svchost.exe -k LocalSystemNetworkRestricted C:\Windows\System32\svchost C:\Program Files (x86)\Common Files\Steam\SteamService.exe /RunAsService "C:\Program Files (x86)\Common Files\Steam\SteamService.exe" /RunAsService and I need to find these paths' actual locations. So, respectively, the above would be: C:\Windows\System32\svchost.exe C:\Windows\System32\svchost.exe C:\Program Files (x86)\Common Files\Steam\SteamService.exe C:\Program Files (x86)\Common Files\Steam\SteamService.exe What's the best way to go about doing this? Does windows have an API function to accomplish it? I essentially am trying to figure out what executable CreateProcess will call if I pass it that path. Thanks! Billy3

• Extracting dates from html meta data in FAST-ESP

  - by Neil

  During document processing I want to extract all dates from html meta data and then identify the latest date which will be used to populate a date field (dtgeneric1). <meta name="OriginalPublicationDate" content="2010/04/21 12:06:36" /> <meta name="LastModificationDate" content="2010/04/22 14:10:16" /> + other non-date meta data Inspection using spy stages shows that our pipeline already adds meta_* attributes but the meta data names will be different across documents from different sources. #### ATTRIBUTE meta_originalpublicationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/21 12:06:36 #### ATTRIBUTE meta_lastmodificationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/22 14:10:16 + other non-date meta attributes Ideally we would like to pass all the meta_* attributes to a Python stage and use that to work out which are dates and which is the largest but there seems to be no way of specifying "all meta attributes" as input. Has anyone done something similar and can offer any advice on the best way to do this. Thanks Neil

• What can i do about an ObjectDisposedException in a dll i cannot access?

  - by djerry

  Hey guys, I'm using a dll to monitor calls (Atapi.dll). Sometimes when events occur, there's an ObjectDisposedException. This seems to be random, i don't know what causes it. I can't debug it and i don't have the source code to it. The events that cause the exception are call events (conencting calls) through Tapi 2.0. It does not causes my app to crash. If i press on the continue button of the window visual studio is generating, the app continues ignoring the exception, but i'd rather not see it happening. I tried catching all code (not much) i have writting, but nothing catches it, and it also says i cannot debug it, because it is thrown in the dll. Does anyone have any idea how to solve or get pass this obstacle? Thanks in advance.

• Specific checkboxes checked in symfony 1.4

  - by Tom

  Hi, I'm able to do the following for all checkboxes in a set (in an action): $this->form->getWidget('some_form_field')->setAttribute('checked', 'checked'); ... but I'm unable to set specific checkboxes to ticked on the basis of data returned from the db. I'm after something like: $this->form->getWidget('some_form_field')->setAttributes(array(....)); ... where I can refer to the specific checkboxes to be ticked somehow, or pass an array to it. There's nothing in the symfony documentation on this specifically and I've had enough of trying a dozen combinations to get it work. Any help would be appreciated. Thanks.

• Function parameter types in Python

  - by Leif Andersen

  Unless I'm mistaken, creating a function in python works like this def my_func(param1, param2): /*stuff*/ However, you don't actually give the types of those parameters. Also, if I remember, python is a strongly typed language, as such, it seams like python shouldn't let you pass in a parameter of a different type then the function creator expected. However, how does python know that the user of the function is passing in the proper types? Or will the program just die if it's the wrong type, assuming the function actually uses the parameter? Or do you have to specify the type/I'm missing something? Thank you.

• Combine guava's ImmutableList and varargs

  I want create constructor that will take one or more integers and save it into field as ImmutableList. According to "The right way to use varargs to pass one or more arguments" by Bloch's Item 42 I create smt like class Foo{ private final ImmutableList<Integer> bar; public Foo(Integer first, Integer... other) { this.bar = ImmutableList.<Integer>builder() .add(first) .addAll(Arrays.asList(other)) .build(); } } Why builder doesn't get generic automatically? And, as it smells. How I can rewrite it?

• Entity Framework - Using a list as a paramater in a compiled query

  - by vdh_ant

  Hi guys Just wondering if anyone knows whether I should be able to pass in list into a compiled query and have the query perform a contains operation? The reason why I ask is that I have a scenario where I need to do this, yet at run time I am getting the following error... The specified parameter 'categories' of type 'System.Collections.Generic.List`1[[System.Int32, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' is not valid. Only scalar parameters (such as Int32, Decimal, and Guid) are supported. I can understand why this might be the case but I was wondering if anyone knows a way around it. Cheers Anthony

• PHP and writing clean code

  - by Pirkka

  Hello Im trying to find best practices to write PHP. I just wonder is this a bad habit. For example, processing variables. $var = 1 $var = doSomething($var); $var = doSomething2($var); $var = doSomething3($var); It looks a bit awful. Here is a example of a real code that I just did: $this->rSum = explode(",", $this->options["rSum"]); $this->rSum = array_combine(array_values($this->rSum), array_fill(0, count($this->rSum), 0)); If someone could pass me some good tutorials of writing cleaner code generally it would be nice! Its me again asking stupid questions. :)
