  • Problem installing RMagick rubygem on Centos 5

    - by Keith Pitty
    I'm having problems installing the RMagick rubygem on Centos 5. I've followed the steps detailed in http://rmagick.rubyforge.org/install2-linux.html but when I try: sudo gem install rmagick the result is: Building native extensions. This could take a while...

  • ASP.NET MVC 2: Mechanics behind an Order / Order Line in a edit form

    - by Dr. Zim
    In this question I am looking for links/code to handle an IList<OrderLine> in an MVC 2 edit form. Specifically I am interested in sending a complete order to the client, then posting the edited order back to an object (to persist) using: Html.EditorFor(m = m.orderlines[i]) (where orderlines is an enumerable object) Editing an Order that has multiple order lines (two tables, Order and OrderLine, one to many) is apparently difficult. Is there any links/examples/patterns out there to advise how to create this form that edits an entity and related entities in a single form (in C# MVC 2)? The IList is really throwing me for a loop. Should I have it there (while still having one form to edit one order)? How could you use the server side factory to create a blank OrderLine in the form while not posting the entire form back to the server? I am hoping we don't treat the individual order lines with individual save buttons, deletes, etc. (for example, they may open an order, delete all the lines, then click cancel, which shouldn't have altered the order itself in either the repository nor the database. Example classes: public class ViewModel { public Order order {get;set;} // Only one order } public class Order { public int ID {get;set;} // Order Identity public string name {get;set;} public IList<OrderLine> orderlines {get;set;} // Order has multiple lines } public class OrderLine { public int orderID {get;set;} // references Order ID above public int orderLineID {get;set;} // Order Line identity (need?) public Product refProduct {get;set;} // Product value object public int quantity {get;set;} // How many we want public double price {get;set;} // Current sale price }

  • Analyzing data from same tables in diferent db instances.

    - by Oscar Reyes
    Short version: How can I map two columns from table A and B if they both have a common identifier which in turn may have two values in column C Lets say: A --- 1 , 2 B --- ? , 3 C ----- 45, 2 45, 3 Using table C I know that id 2 and 3 belong to the same item ( 45 ) and thus "?" in table B should be 1. What query could do something like that? EDIT Long version ommited. It was really boring/confusing EDIT I'm posting some output here. From this query: select distinct( rolein) , activityin from taskperformance@dm_prod where activityin in ( select activityin from activities@dm_prod where activityid in ( select activityid from activities@dm_prod where activityin in ( select distinct( activityin ) from taskperformance where rolein = 0 ) ) ) I have the following parts: select distinct( activityin ) from taskperformance where rolein = 0 Output: http://question1337216.pastebin.com/f5039557 select activityin from activities@dm_prod where activityid in ( select activityid from activities@dm_prod where activityin in ( select distinct( activityin ) from taskperformance where rolein = 0 ) ) Output: http://question1337216.pastebin.com/f6cef9393 And finally: select distinct( rolein) , activityin from taskperformance@dm_prod where activityin in ( select activityin from activities@dm_prod where activityid in ( select activityid from activities@dm_prod where activityin in ( select distinct( activityin ) from taskperformance where rolein = 0 ) ) ) Output: http://question1337216.pastebin.com/f346057bd Take for instace activityin 335 from first query ( from taskperformance B) .

  • Multimedia files written over WAN are getting truncated

    - by Dean
    I use the windows Multimedia API to create .wav files. 1. Open file with mmsioOpen 2. Creates WAVE,frm and data chunks using mmioCreateChunk 3. Write audio data using mmioWrite 4. Ascend out of the chunks using mmioAscend 5. Close file using mmioClose The file is being written into a temporary location, so after it has been closed it gets copied to another location using the CopyFile. This program is written in C++ and works great until the file it is writing resides over a WAN in a different city or country. The end result is a wav file that should be 20-30 seconds long ends up being 4 secodns long. It is always the last bit that is missing, so when you play it back it just stops before then of the recording. I initially thought that maybe I was copying the file too soon so as a test I put in a pause of 30 seconds after closing the file using Sleep(30000), but this made no difference to either it being truncated or by how much. I have modified the program to write to a file in parrallel using CreateFile and WriteFile, and the result is the same, so it is not an issue specifically with the mmio API's. Does anyone have any ideas why this is happening and if there is a work-around to it? I suspect that I may end up having the temporary location on the local drive, but this is quite a big change to the application as well as existing deployments. thanks for everyones time Dean

  • VB.NET invalid cast exception

    - by user127147
    Hi there, I have a simple application to store address details and edit them. I have been away from VB for a few years now and need to refreash my knowledge while working to a tight deadline. I have a general Sub responsible for displaying a form where user can add contact details (by pressing button add) and edit them (by pressing button edit). This sub is stored in a class Contact. The way it is supposed to work is that there is a list with all the contacts and when new contact is added a new entry is displayed. If user wants to edit given entry he or she selects it and presses edit button Public Sub Display() Dim C As New Contact C.Cont = InputBox("Enter a title for this contact.") C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text frmStart.lstContact.Items.Add(C.Cont.ToString) End Sub I call it from the form responsible for adding new contacts by Dim C As New Contact C.Display() and it works just fine. However when I try to do something similar using the edit button I get errors - "Unable to cast object of type 'System.String' to type 'AddressBook.Contact'." Dim C As Contact If lstContact.SelectedItem IsNot Nothing Then C = lstContact.SelectedItem() C.Display() End If I think it may be something simple however I wasn't able to fix it and given short time I have I decided to ask for help here. Thank you

  • Thumbnail Provider not working

    - by Dan
    I'm trying to write a Windows Explorer thumbnail handler for our custom file type. I've got this working fine for the preview pane, but am having trouble getting it to work for the thumbnails. Windows doesn't even seem to be trying to call the DllGetClassObject entry point. Before I continue, note that I'm using Windows 7 and unmanaged C++. I've registered the following values in the registry: HKCR\CLSID\<my guid> HKCR\CLSID\<my guid>\InprocServer32 (default value being path to my DLL) HKCR\CLSID\<my guid>\InprocServer32\ThreadingModel (value = "Apartment") HKCR\.<my ext>\shellex\{E357FCCD-A995-4576-B01F-234630154E96} (value = my guid) I've also tried using the Win SDK sample, and that doesn't work. And also the sample project in this article (http://www.codemonkeycodes.com/2010/01/11/ithumbnailprovider-re-visited/), and that doesn't work. I'm new to shell programming, so not really sure the best way of debugging this. I've tried attaching the debugger to explorer.exe, but that doesn't seem to work (breakpoints get disabled, and none of my OutputDebugStrings get displayed in the output window). Note that I tried setting the "DesktopProcess" in the registry as described in the WinSDK docs for debugging the shell, but I'm still only seeing one explorer.exe in the task manager - so that "may" be why I can't debug it?? Any help with this would be greatly appreciated! Regards, Dan.

  • Question about SQL Server HierarchyID depth-first performance

    - by AndalusianCat
    I am trying to implement hierarchyID in a table (dbo.[Message]) containing roughly 50,000 rows (will grow substantially in the future). However it takes 30-40 seconds to retrieve about 25 results. The root node is a filler in order to provide uniqueness, therefor every subsequent row is a child of that dummy row. I need to be able to traverse the table depth-first and have made the hierarchyID column (dbo.[Message].MessageID) the clustering primary key, have also added a computed smallint (dbo.[Message].Hierarchy) which stores the level of the node. Usage: A .Net application passes through a hierarchyID value into the database and I want to be able to retrieve all (if any) children AND parents of that node (besides the root, as it is filler). A simplified version of the query I am using: @MessageID hierarchyID /* passed in from application */ SELECT m.MessageID, m.MessageComment FROM dbo.[Message] as m WHERE m.Messageid.IsDescendantOf(@MessageID.GetAncestor((@MessageID.GetLevel()-1))) = 1 ORDER BY m.MessageID From what I understand, the index should be detected automatically without a hint. From searching forums I have seen people utilizing index hints, at least in the case of breadth-first indexes, as apparently CLR calls may be opaque to the query optimizer. I have spent the past few days trying to find a solution for this issue, but to no avail. I would greatly appreciate any assistance, and as this is my first post, I apologize in advance if this would be considered a 'noobish' question, I have read the MS documentation and searched countless forums, but have not came across a succinct description of the specific issue.

  • LINQ to SQL - Left Outer Join with multiple join conditions

    - by dan
    I have the following SQL which I am trying to translate to LINQ: SELECT f.value FROM period as p LEFT OUTER JOIN facts AS f ON p.id = f.periodid AND f.otherid = 17 WHERE p.companyid = 100 I have seen the typical implementation of the left outer join (ie. into x from y in x.DefaultIfEmpty() etc.) but am unsure how to introduce the other join condition ('AND f.otherid = 17') EDIT Why is the 'AND f.otherid = 17' condition part of the JOIN instead of in the WHERE clause? Because f may not exist for some rows and I still want these rows to be included. If the condition is applied in the WHERE clause, after the JOIN - then I don't get the behaviour I want. Unfortunately this: from p in context.Periods join f in context.Facts on p.id equals f.periodid into fg from fgi in fg.DefaultIfEmpty() where p.companyid == 100 && fgi.otherid == 17 select f.value seems to be equivalent to this: SELECT f.value FROM period as p LEFT OUTER JOIN facts AS f ON p.id = f.periodid WHERE p.companyid = 100 && AND f.otherid = 17 which is not quite what I'm after.

  • Doubts About Core Data NSManagedObject Deep Copy

    - by Jigzat
    Hello everyone, I have a situation where I must copy one NSManagedObject from the main context into an editing context. It sounds unnecessary to most people as I have seen in similar situations described in Stackoverflow but I looks like I need it. In my app there are many views in a tab bar and every view handles different information that is related to the other views. I think I need multiple MOCs since the user may jump from tab to tab and leave unsaved changes in some tab but maybe it saves data in some other tab/view so if that happens the changes in the rest of the views are saved without user consent and in the worst case scenario makes the app crash. For adding new information I got away by using an adding MOC and then merging changes in both MOCs but for editing is not that easy. I saw a similar situation here in Stackoverflow but the app crashes since my data model doesn't seem to use NSMutableSet for the relationships (I don't think I have a many-to-many relationship, just one-to-many) I think it can be modified so I can retrieve the relationships as if they were attributes for (NSString *attr in relationships) { [cloned setValue:[source valueForKey:attr] forKey:attr]; } but I don't know how to merge the changes of the cloned and original objects. I think I could just delete the object from the main context, then merge both contexts and save changes in the main context but I don't know if is the right way to do it. I'm also concerned about database integrity since I'm not sure that the inverse relationships will keep the same reference to the cloned object as if it were the original one. Can some one please enlighten me about this?

  • What Is The Proper Location For One-Offs In VCS Repos?

    - by Joe Clark
    I have recently started using Mercurial as our VCS. Over the years, I have used RCS, CVS, and - for the last 5 years - SVN. Back 13 years ago, when I primarily used CVS and RCS, large projects went into CVS and one-offs were edited in place on the specific server and stored in RCS. This worked well as the one-offs were usually specific to the server and the servers were backed up nightly. Jump forward a decade and a lot of the one-off scripts became less centralized - they might be needed on any server at some random time. This was also OK, because now I was a begrudging SVN user. Everything (except for docs) got dumped into one repo. Jump to 2010. Now I am using Mercurial and am putting large projects in their own repo again. But what to do with the one-offs? The options as I see them: A repo for each script. It seems a bit cluttered to create a repo for every one page script that might get ran once a year. RCS Not an option. There are many possible servers that might need a specific script. Continuing to use SVN just for one-offs. No. There no advantage I see over the next option. Create a repo in Mercurial named "one-offs". This seems the most workable. The last option seems the best to me - however; is there a best practice regarding this? You also might be wondering if these scripts are truly one-offs if they will be reused. Some of them may be reused 6 months or a year from now - some, never. However, nearly all of them involve several man-hours of work due to either complex logic or extensive error checking. Simply discarding them is not efficient.

  • Java: How do you really force a GC using JVMTI's ForceGargabeCollection?

    - by WizardOfOdds
    I'm not looking for the usual "you can only hint the GC in Java using System.gc()" answers, this is not at all what this question is about. My questions is not subjective and is based on a reality: GC can be forced in Java for a fact. A lot of programs that we use daily do it: IntelliJ IDEA, NetBeans, VisualVM. They all can force GC to happen. How is it done? I take it they're all using JVMTI and more specifically the ForceGarbabeCollection (notice the "Force") but how can I try it for myself? http://java.sun.com/javase/6/docs/platform/jvmti/jvmti.html#ForceGarbageCollection Also note that this question is not about "why" I'd want to do this: the "why" may be "curiosity" or "we're writing a program similar to VisualVM", etc. The question is really "how do you force a GC using JVMTI's ForceGarbageCollection"? Does the JVM needs to be launched with any special parameters? Is any JNI required? If so, what code exactly? Does it only work on Sun VMs? Any complete and compilable example would be most welcome.

  • codingBat separateThousands using regex (and unit testing how-to)

    - by polygenelubricants
    This question is a combination of regex practice and unit testing practice. Regex part I authored this problem separateThousands for personal practice: Given a number as a string, introduce commas to separate thousands. The number may contain an optional minus sign, and an optional decimal part. There will not be any superfluous leading zeroes. Here's my solution: String separateThousands(String s) { return s.replaceAll( String.format("(?:%s)|(?:%s)", "(?<=\\G\\d{3})(?=\\d)", "(?<=^-?\\d{1,3})(?=(?:\\d{3})+(?!\\d))" ), "," ); } The way it works is that it classifies two types of commas, the first, and the rest. In the above regex, the rest subpattern actually appears before the first. A match will always be zero-length, which will be replaceAll with ",". The rest basically looks behind to see if there was a match followed by 3 digits, and looks ahead to see if there's a digit. It's some sort of a chain reaction mechanism triggered by the previous match. The first basically looks behind for ^ anchor, followed by an optional minus sign, and between 1 to 3 digits. The rest of the string from that point must match triplets of digits, followed by a nondigit (which could either be $ or \.). My question for this part is: Can this regex be simplified? Can it be optimized further? Ordering rest before first is deliberate, since first is only needed once No capturing group Unit testing part As I've mentioned, I'm the author of this problem, so I'm also the one responsible for coming up with testcases for them. Here they are: INPUT, OUTPUT "1000", "1,000" "-12345", "-12,345" "-1234567890.1234567890", "-1,234,567,890.1234567890" "123.456", "123.456" ".666666", ".666666" "0", "0" "123456789", "123,456,789" "1234.5678", "1,234.5678" "-55555.55555", "-55,555.55555" "0.123456789", "0.123456789" "123456.789", "123,456.789" I haven't had much experience with industrial-strength unit testing, so I'm wondering if others can comment whether this is a good coverage, whether I've missed anything important, etc (I can always add more tests if there's a scenario I've missed).

  • Call Multiple Stored Procedures with the Zend Framework

    - by Brian Fisher
    I'm using Zend Framework 1.7.2, MySQL and the MySQLi PDO adapter. I would like to call multiple stored procedures during a given action. I've found that on Windows there is a problem calling multiple stored procedures. If you try it you get the following error message: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. I found that to work around this issue I could just close the connection to the database after each call to a stored procedure: if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { //If on windows close the connection $db->closeConnection(); } This has worked well for me, however, now I want to call multiple stored procedures wrapped in a transaction. Of course, closing the connection isn't an option in this situation, since it causes a rollback of the open transaction. Any ideas, how to fix this problem and/or work around the issue.

  • Error displaying a WinForm in Design mode with a custom control on it.

    I have a UserControl that is part of a Class library. I reference this project from my solution. This adds a control from the referenced project to my toolbox. I add tghe control to a form. Everything looks good, I compile all and run. Perfect... But when I close the .frm with the control on it and re-open it, I get this error. The code continues to run.

  • Saving/Associating slider values with a pop-up menu

    - by James
    Hi, Following on from a question I posted yesterday about GUIs, I have another problem I've been working with. This question related to calculating the bending moment on a beam under different loading conditions. On the GUI I have developed so far, I have a number of sliders (which now work properly) and a pop-up menu which defines the load case. I would like to be able to select the load case from the pop-up menu and position the loads as appropriate, in order to define each load case in turn. The output that I need is an array defining the load case number (the rows) and a number of loading parameters (the itensity and position of the loads, which are controlled by the sliders). The problem I am having is that I can produce this array (of the size I need) and define the loading for one load case (by selecting the pop-up menu) using the sliders, but when I change the popup menu again, the array only keeps the loading for the load case selected by the pop-up menu. Can anyone suggest an approach I can take with (specifically to store the variables from each load case) or an example that illustrates a similar solution to the problem? The probem may be a bit vague, so please let me know if anything needs clearing up. Many Thanks, James

  • Getting error: "This webpage is not available" for my chrome app's options page

    - by Don Rhummy
    My CRX had the proper html page options.html in it, the manifest declares it properly (it shows up as a link on the chrome://extensions page) but when I click that link, Chrome gives the error: This webpage is not available The webpage at chrome-extension://invalid/ might be temporarily down or it may have moved permanently to a new web address. It says "invalid" but the app runs perfectly well (all the content scripts run, the background created a database and saved to it). Why would it show as invalid? Why doesn't it have the extensions' id? Here's the manifest: { "manifest_version": 2, "name": "MyAPP", "description": "My App", "version": "0.0.0.32", "minimum_chrome_version": "27", "offline_enabled": true, "options_page": "options.html", "icons": { "16": "images/icon16.png", "48": "images/icon48.png", "128": "images/icon128.png" }, "app": { "background": { "scripts": [ "scripts/background.js" ] } }, "permissions": [ "unlimitedStorage", "fullscreen", { "fileSystem": [ "write" ] }, "background", "<all_urls>", "tabs" ] } Does it need to be declared in "web_accessible_resources"? Any idea what's wrong? Update Adding to "web_accessible_resources" does not fix the issue. I added everything on that page too. update 2 It looks like it might be a Chrome bug for packaged apps. When I remove the "app" section in the manifest, it works! This is a bug since the Chrome app documentation states that apps can have options pages: https://developer.chrome.com/apps/options.html

  • Archive log transfer from Oracle 9i to Oracle 10g

    - by Jamie Love
    Hi all, I have a situation where I need to transfer Oracle 9i archive logs to an Oracle 10g database, from where they are to be mined by a log-miner and then used by an Oracle streams capture/apply processes. (Oracle 9 archive logs can be read by the Oracle 10 logminer - I can manually copy the archive logs across, manually register them and have them mined, captured then applied). The difficulty is that the way Oracle does archive log transfer changed quite a bit between 9i and 10g and setting up the 9i database to transfer to the remote machine like so: log_archive_dest_state_2 = enable log_archive_dest_2 = "service=OTHERMACHINE arch optional" no longer works. I get this in the 9i logs: *** 2009-05-22 04:03:44.149 RFS network connection lost at host 'OTHERMACHINE' Error 3113 attaching RFS server to standby instance at host 'OTHERMACHINE' Error 3113 attaching to destination LOG_ARCHIVE_DEST_2 standby host 'OTHERMACHINE' Heartbeat failed to connect to standby 'OTHERMACHINE'. Error is 3113. *** 2009-05-22 04:03:44.150 kcrrfail: dest:2 err:3113 force:0 ORA-03113: end-of-file on communication channel And in the 10g log I get: Fri May 22 04:07:42 2009 WARNING: inbound connection timed out (ORA-3136) My question is: Does anyone know how I could configure my 9i or 10g server such that the 10g server will accept the 9i connection in such a way that I can transfer the 9i archive logs to the 10g server. It would be a bonus if the archive logs would be automatically registered in the 10g server. Note I have not set up a full DataGuard configuration here and the 10g database is not a secondary server. Thanks for any suggestions. Edit Note that I can log on to the 10g server from the 9i server via sqlplus, so connectivity is not the problem Edit 2 After a large amount of time searching for a solution, I've finally decided that such a mechanism doesn't work, and that a non-Oracle method of transferring archive logs from 9i to 10g will need to be used (e.g. rsync).

  • How to save a picture to a file?

    - by Peter vdL
    I'm trying to use a standard Intent that will take a picture, then allow approval or retake. Then I want to save the picture into a file. Here's the Intent I am using: Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); startActivityForResult( intent, 22 ); The docs at http://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE say "The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT." I don't pass extra output, I hope to get a Bitmap object in the extra field of the Intent passed into onActivityResult() (for this request). So where/how do you extract it? Intent has a getExtras(), but that returns a Bundle, and Bundle wants a key string to give you something back. What do you invoke on the Intent to extract the bitmap?

  • what is this internet explorer (javascript?) syntax error -2146827286?

    - by ben
    Hi everyone, So, I've been trying to troubleshoot this bug where some big percentage of windows users who are on my ajax (jquery) web app are not able to play. I haven't been able to reproduce it on my end with a windows 7 IE8 running in a parallels vm. The main problem seems to be in the javascript somewhere because what users are complaining about is an ajax button isn't working. They click it and nothing happens, so either the event isn't firing, or my ajax call is failing, and possibly the return from the ajax could be failing. After trying some ideas, a friend suggested I check out damnit! https://damnit.jupiterit.com/ which will catch exceptions in javascript and email them to you. This is a pretty awesome tool! So, now i have a little more data, but, am stuck. Basically it seems like the majority of the exceptions seem to be complaining about a syntax error. I will paste the samples below. message: Syntax error number: -2146827286 description: Syntax error Browser: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; .NET CLR 1.0.3705; OfficeLiveConnector.1.3; OfficeLivePatch.0.0) What's interesting is that the syntax error is consistently occurring in browsers reporting MSIE 8.0 but with windows vista, xp, and below, so older OS with the latest IE. Does anyone know of this error? Could this possibly be some weird slow computer/slow internet connection thing where may be my javascript files aren't fully loaded before I call the functions. I am using the jquery $(document).ready() to wait before I setup anything.

  • STLport crash (race condition, Darwin only?)

    - by Jonas Byström
    When I run STLport on Darwin I get a strange crash. (Haven't seen it anywhere else than on Mac, but exactly same thing crash on both i686 and PowerPC.) This is what it looks like in gdb: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: 13 at address: 0x0000000000000000 [Switching to process 21097] 0x000000010120f47c in stlp_std::__node_alloc_impl::_M_allocate () It may be some setting in STLport, I noticed that Mac.h and MacOSX.h seemed far behind on features. I also know that it it must be some type of race condition, since it doesn't occur just by calling this method (implicity called). The crash happens mainly when I push the system, running 10 simultaneous threads that do a lot of string handling. Other theories I come up with have to do with compiler flags (configure script) and g++ 4.2 bugs (seems like 4.4.3 isn't on Mac yet with Objective-C support, which I need to link with). HELP!!! :) Edit: I run unit tests, which do all sorts of things. This problem arise when I start 10 threads that push the system; and it always comes down to std::string::append which eventually boils down to _M_allocate. Since I can't even get a descent dump of the code that's causing the problem, I figure I'm doing something bad. Could it be so since it's trying to execute at instruction pointer 0x000...000? Are dynlibs built as DLLs in Windows with a jump table? Could it perhaps be that such a jump table has been overwritten for some reason? That would probably explain this behavior. (The code is huge, if I run out of other ideas, I'll post a minimum crashing sample here.)

  • WCF Double Hop questions about Security and Binding.

    - by Ken Maglio
    Background information: .Net Website which calls a service (aka external service) facade on an app server in the DMZ. This external service then calls the internal service which is on our internal app server. From there that internal service calls a stored procedure (Linq to SQL Classes), and passes the serialized data back though to the external service, and from there back to the website. We've done this so any communication goes through an external layer (our external app server) and allows interoperability; we access our data just like our clients consuming our services. We've gotten to the point in our development where we have completed the system and it all works, the double hop acts as it should. However now we are working on securing the entire process. We are looking at using TransportWithMessageCredentials. We want to have WS2007HttpBinding for the external for interoperability, but then netTCPBinding for the bridge through the firewall for security and speed. Questions: If we choose WS2007HttpBinding as the external services binding, and netTCPBinding for the internal service is this possible? I know WS-* supports this as does netTCP, however do they play nice when passing credential information like user/pass? If we go to Kerberos, will this impact anything? We may want to do impersonation in the future. If you can when you answer post any reference links about why you're answering the way you are, that would be very helpful to us. Thanks!

  • ORM model and DAO in my particular case

    - by EugeneP
    I have the DB structure as follows: table STUDENT (say, id, surname, etc) table STUDENT_PROPERTIES (say, name_of_the_property:char, value_of_the_property:char, student_id:FK) table COURSE (id, name, statusofcourse_id) table STATUSOFCOURSE (id, name_of_status:char ('active','inactive','suspended' etc)) table STUDENT_COURSE (student_id,course_id,statusofcourse_id) Let's try to pick up domain objects in my database: Student and Course are main entities. Student has a list of courses he attends, also he has a list of properties, that is all for this student. Next, Course entitity. It may contain a list of students that attend it. But in fact, the whole structure looks like this: the starting point is Student, with it's PK we can look a list of his properties, then we look into the STUDENT_COURSE and extract both FK of the Course entity and also the Status of the combination, it would look like "Student named bla bla, with all his properties, attends math and the status of it is "ACTIVE". now, quotation 1) Each DAO instance is responsible for one primary domain object or entity. If a domain object has an independent lifecycle, it should have its own DAO. 2) The DAO is responsible for creations, reads (by primary key), updates, and deletions -- that is, CRUD -- on the domain object. Now, first question is What are entities in my case? Student, Course, Student_Course, Status = all except for StudentProperties? Do I have to create a separate DAO for every object?

  • WinForms data binding with a Save button?

    - by Mat
    How is data binding in C# WinForms supposed to work when you have a Save button? I don't want the data updated until I press Save! I have two forms (list and detail) backed by a BindingList<T> collection and my custom object from that collection, respectively. I can bind each form to the list or object appropriately. However, any changes made in the detail form are immediately reflected in the list form - I don't want to save the changes and update the details shown in the list until the Save button is pressed. Is data binding designed to support this? Is there a common pattern for doing so? Whichever way I look at it, binding doesn't seem to be able to support this scenario. I've considered the following: Pass a clone of the object to the detail form, but then I have to reconcile the changes on Save - changes may have been made to the copy in the list in the meantime. Implementing IEditableObject and calling EndEdit on save almost works as I can prevent the list being notified of the changes made until Save is pressed, but if something else causes a refresh the list is updated with the interim data. I'm currently left with dispensing with data binding in my detail view, and doing it all manually. Which is rather annoying.

  • Log4net Logging Problem : Very simple file appender logging not working

    - by contactmatt
    Here's my web.config information <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <root> <level value="ALL" /> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\log-file.txt" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> </log4net> ... Here's the code that initalizes the logger protected void SendMessage() { log4net.Config.XmlConfigurator.Configure(); ILog log = LogManager.GetLogger(typeof(Contact)); ... log.Info("here we go!"); log.Debug("debug afasf"); ... } it doesn't work, no matter what I seem to do. I am referencing the 'log4net.dll' correctly, and by debugging the application i can see that the log object is getting initiated properly. This is a asp.net 3.5 framework web project. Any ideas/suggestions? I thought originally this error may be due to a file write permission constraint, but that doesn't seem to be the case (or so I think).
