• Using graphical ActiveX (COM) controls in WinForms project

  - by alex

  I have a collection (set) of ActiveX controls. I recieved them from our vendor company. I created a wrappers for them using tlbimp.exe and aximp.exe. All non-graphical controls work good. All graphical controls don't react on some methods. When I call their methods I get: TargetInvocativeException (InnerException is null). or Attempt to read/write protected memory. Our vendor company assure that their graphical activex controls work good. But they don't provide support service, so I have to find solution of my problem alone. And some more, All graphical activex controls don't react on mouseclick or any other mouse manipulations. But documentation says: it must change the color on mouse click. Maybe, someone have same symptoms and can help me ! I googled over that problem many pages but they don't help me. Maybe it's some Visual Studio settings or compiler options ? I use VS 2005.

• When does a WPF adorner layer first become available?

  - by aoven

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

• How do I create a .NET Web Service that Posts items to a users Facebook Wall?

  - by Jourdan

  I'm currently toying around with the Clarity .NET Facebook API but am finding certain situations with authentication to be kind of limiting. I keep going through the tutorials but always end up hitting a brick wall with what I want to do. Perhaps I just cannot do it? I want to make a Web Service that takes in the require credentials (APIKey, SecretKey, UsersId (or Session Key?) and whatever else I would need), and then do various tasks: Post to users wall, add events etc. The problem I am having is this: The current documentation, examples and support provide a way to do this within the context of a Web site. Within this context, the required "connect" popup can be initiated and allow the user to authenticate and and connect the application. From that point on the Web can go on with its business to do what it needs to do. If I close the browser and come back to the page, I have to push the connect button again. Except this time, since I was already logged into facebook, I don't have to go through the whole connection process. But still ... How do applications like Tweetdeck get around this? They seemingly have you connect once, when you install their application, and you don't have to do it again. I would assume that this same idea would have to applied towards making a web service because: You don't know what context the user is in when making the Web service call. The web service methods being called could be coming from a Windows Form app, or code behind in a workflow.

• Missing chars in JpGraph

  - by Álvaro G. Vicario

  I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?

• Globally disabling FxCop errors in TeamCity

  - by Dave

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

• What exactly is the difference between the Dreamhost IDE and Netbeans?

  - by mikemick

  I just started using Netbeans about a week ago, and really like it thus far. Now I'm seeing something about Dreamhost IDE which I guess is a program that is built using the Netbeans platform. I use Dreamhost as the hosting company for many of my projects. What is the benefit of using Dreamhost IDE over Netbeans? Documentation on the software is non-existent from what I can tell (not even a mention in the Dreamhost wiki). All I was able to find was a short description of what it was on a Sourceforge download page, and I found a short silent video on YouTube demoing it. So I guess I'm asking, what features is it bringing to the table, and what is the difference between it and Netbeans? The description on the Sourceforge page is as follows (typos retained)... DreamHost IDE is php and ruby integrated development environment built on NetBeans IDE and provides easy deploy of your applications to the DreamHost services. Also provides you an easy eay hew to setup these services. Maybe the answer is in the description, and I just don't comprehend it?

• Can't open Websphere Portal 7.0 Login Page after its integration with a custom user registry?

  - by jack_sparrow

  I am currently working on a project related to Websphere Portal 7.0 on Windows Server 2008 R2,64 bit. I am trying to integrate websphere portal with my custom user registry.I have completed all the steps required to implement custom user registry in portal as given in IBM documentation.I am adding my custom repository to the default federated repositories of Portal 7.0.I have made the required changes under VMM Federated CUR Properties section in wkplc.properties.I am using configengine.bat file to configure Portal with user registry. But even completing all the steps,when I am trying to open the Portal Login Page through http://ip-address:port_of_portal/wps/portal ,it is throwing an exception on the console: "Error 500: com.ibm.wps.resolver.data.exceptions.URIProcessingIOException: EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: [EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null] " and in logs Systemout.log "EJPSB0005E: Exception occurred during creation of the principal with Name uid=portal,o=defaultWIMFileBasedRealm and Principal Type USER caused by com.ibm.portal.puma.MemberNotFoundException: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null".

• TinyMCE Image Alignment

  - by will.earp.co.uk

  TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

• Swing data binding frameworks

  - by Ahe

  Hi Almost the same question has been asked a year ago, but the there has been some new development in this area. Selecting a (data binding) framework for swing application seems to be quite difficult. JSR-295 is abandoned, many swing frameworks which provide binding are work-in-progress, abandoned or too heavy for my quite simple app. JGoodies Swing suite is expensive, but luckily its libraries are free. Has anyone any real-world experience of new UFaceKit. It looks promising, but quite immature. I am particularly interested in Swing implementation and documentation. Any insight on UFaceKits development schedule would be appreciated, because I can hold by framework choice for a while. Requirements are not anything fancy, just working binding with a nice API. I also found Mogwai dataBinding, but it seems quite incomplete and requires manual synchronization activation, which makes it useless compared to coarse grained synchronization easily written by hand. Incomplete frameworks include at least Spring RCP and many JSR-296 forks. So, is the JGoodies data binding really the only realistic choice? Or are there any other viable solutions available?

• Asynchronous NSURLConnection Throws EXC_BAD_ACCESS

  - by Sheehan Alam

  I'm not really sure why my code is throwing a EXC_BAD_ACCESS, I have followed the guidelines in Apple's documentation: -(void)getMessages:(NSString*)stream{ NSString* myURL = [NSString stringWithFormat:@"http://www.someurl.com"]; NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:myURL]]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { receivedData = [[NSMutableData data] retain]; } else { NSLog(@"Connection Failed!"); } } And my delegate methods #pragma mark NSURLConnection Delegate Methods - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { // This method is called when the server has determined that it // has enough information to create the NSURLResponse. // It can be called multiple times, for example in the case of a // redirect, so each time we reset the data. // receivedData is an instance variable declared elsewhere. [receivedData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { // Append the new data to receivedData. // receivedData is an instance variable declared elsewhere. [receivedData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { // release the connection, and the data object [connection release]; // receivedData is declared as a method instance elsewhere [receivedData release]; // inform the user NSLog(@"Connection failed!

Even if that method simply contains an NSLog, I get the error. Note: receivedData is an NSMutableData* in my header file

• How do I make Views fill the full width of their parent in my Android app?

  - by Omega

  I have the following layout defined for one of my Activities: <?xml version="1.0" encoding="utf-8"?> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TableRow android:id="@+id/TableRow01" android:layout_height="wrap_content" android:layout_width="fill_parent"> <EditText android:text="Resource Name" android:id="@+id/ResourceName" android:lines="1" android:isScrollContainer="false"></EditText> </TableRow> <TableRow android:id="@+id/TableRow02" android:layout_height="wrap_content" android:layout_width="fill_parent"> <Button android:id="@+id/Tile" android:text="Tile"></Button> </TableRow> </TableLayout> The layout renders almost correctly, the only problem is that my text box and my button aren't occupying the full width of their respective rows. I've tried specifying fill_parent for the layout width properties, but to no avail, they still only occupy roughly half of the screen. Documentation overall for Android so far has been great, but there are a few scenarios like this one where I hit an invisible wall! Thanks for all the help!

• What are alternatives to Win32 PulseEvent() function?

  - by Bill

  The documentation for the Win32 API PulseEvent() function (kernel32.dll) states that this function is “… unreliable and should not be used by new applications. Instead, use condition variables”. However, condition variables cannot be used across process boundaries like (named) events can. I have a scenario that is cross-process, cross-runtime (native and managed code) in which a single producer occasionally has something interesting to make known to zero or more consumers. Right now, a well-known named event is used (and set to signaled state) by the producer using this PulseEvent function when it needs to make something known. Zero or more consumers wait on that event (WaitForSingleObject()) and perform an action in response. There is no need for two-way communication in my scenario, and the producer does not need to know if the event has any listeners, nor does it need to know if the event was successfully acted upon. On the other hand, I do not want any consumers to ever miss any events. In other words, the system needs to be perfectly reliable – but the producer does not need to know if that is the case or not. The scenario can be thought of as a “clock ticker” – i.e., the producer provides a semi-regular signal for zero or more consumers to count. And all consumers must have the correct count over any given period of time. No polling by consumers is allowed (performance reasons). The ticker is just a few milliseconds (20 or so, but not perfectly regular). Raymen Chen (The Old New Thing) has a blog post pointing out the “fundamentally flawed” nature of the PulseEvent() function, but I do not see an alternative for my scenario from Chen or the posted comments. Can anyone please suggest one? Please keep in mind that the IPC signal must cross process boundries on the machine, not simply threads. And the solution needs to have high performance in that consumers must be able to act within 10ms of each event.

• Facebook connect PHP API - friends_get() returns empty array

  - by Soufiane Hassou

  Couple of hours ago I succeed to get friends_get() to return an array of friends, but, now I don't know if it is my fault or something is wrong in facebooks' end (API problems?). Anyway I used a code from their documentation: <?php require_once 'facebook-platform/php/facebook.php'; $appapikey = ''; //CHANGE THIS $appsecret = ''; //CHANGE THIS $facebook = new Facebook($appapikey, $appsecret); //$user_id = $facebook->require_login(); $fb_user=$facebook->get_loggedin_user(); //$fb_user = $facebook->user; $friends = $facebook->api_client->friends_get(); $friends = array_slice($friends, 0, 10); $i=0; foreach ($friends as $friend) { $personArray = $facebook->api_client->users_getInfo($friend,"name"); $person[$i]=$personArray[0]; $i++; } $i=0; foreach ($person as $f) { echo " ".$f['name']; //MORE DETAILS HERE IN STEP 2 echo "<br />"; $i++; } echo "<br />"; ?> The login is working great, but, I can't retrieve the list of friends and I test also with api_client->pages_isFan and it doesn't seem to work too (says not a fan while the user is).

• Using EclipseLink

  - by Ross Peoples

  I am still new to Java and Eclipse and I'm trying to get my application to connect to a database. I think I want to use EclipseLink, but all of the documentation on the matter assumes you already know everything there is to know about everything. I keep getting linked back to this tutorial: http://www.vogella.de/articles/JavaPersistenceAPI/article.html But it's basically useless because it doesn't tell you HOW to do anything. For the Installation section, it tells you to download EclipseLink and gives you a link to the download page, but doesn't tell you what to do with it after you download. The download page doesn't either. I used the "Install new software" option in Eclipse to install EclipseLink into Eclipse, but it gave me like 4 different options, none of which are explained anywhere. It gave me options JPA, MOXy, SDO, etc, but I don't know which one I need. I just installed them all. Everything on the web assumes you are already a Java guru and things that are second nature to Java devs are never explained, so it's very frustrating for someone trying to learn. So how do I install and USE EclipseLink in my project and what do I need to do to connect it to a Microsoft SQL server? Again, I am new to all of this so I have no clue what to do. Thanks for the help.

• subgraph cluster ranking in dot

  - by Chris Becke

  I'm trying to use graphviz on media wiki as a documentation tool for software. First, I documented some class relationships which worked well. Everything was ranked vertically as expected. But, then, some of our modules are dlls, which I wanted to seperate into a box. When I added the nodes to a cluster, they got edged, but clusters seem to have a LR ranking rule. Or being added to a cluster broke the TB ranking of the nodes as the cluster now appears on the side of the graph. This graph represents what I am trying to do: at the moment, cluster1 and cluster2 appear to the right of cluster0. I want/need them to appear below. <graphviz> digraph d { subgraph cluster0 { A -> {B1 B2} B2 -> {C1 C2 C3} C1 -> D; } subgraph cluster1 { C2 -> dll1_A; dll1_A -> B1; } subgraph cluster2 { C3 -> dll2_A; } dll1_A -> dll2_A; } </graphviz>

• VSDBCMD deployment for additions to third party databases

  - by Sam

  We have some custom objects (stored procedures etc) in an SQL Server 2005 database belonging to an ERP system. The custom objects are in different schemas to the ERP objects. We're using Database Edition .dbproj projects and vsdbcmd deployment for all our custom application databases and would like to similarly manage our custom objects in the ERP database. It's not clear how this can be done without either: Importing all ERP objects (~4000 tables) into the .dbproj and manually keeping them in sync with ERP development. Visual Studio fell over the only time I tried importing these, so I've no idea whether it can actually handle a project of this size. Somehow excluding the ERP schemas (there are two) from the diff process to ensure they don't get dropped by vsdbcmd. I haven't found any documentation which suggests this is possible. I'm aware of the IgnoreDefaultSchema setting, but there are two schemas I need to ignore and I'm not comfortable with the 'default schema' approach - deployment by different users could be disasterous. Has anyone managed to successfully use .dbproj & vsdbcmd for custom additions to a third party database? If not, how do you manage SQL source control & deployment?

• Can't operator == be applied to generic types in C#?

  - by Hosam Aly

  According to the documentation of the == operator in MSDN, For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object. For the string type, == compares the values of the strings. User-defined value types can overload the == operator (see operator). So can user-defined reference types, although by default == behaves as described above for both predefined and user-defined reference types. So why does this code snippet fail to compile? void Compare<T>(T x, T y) { return x == y; } I get the error Operator '==' cannot be applied to operands of type 'T' and 'T'. I wonder why, since as far as I understand the == operator is predefined for all types? Edit: Thanks everybody. I didn't notice at first that the statement was about reference types only. I also thought that bit-by-bit comparison is provided for all value types, which I now know is not correct. But, in case I'm using a reference type, would the the == operator use the predefined reference comparison, or would it use the overloaded version of the operator if a type defined one? Edit 2: Through trial and error, we learned that the == operator will use the predefined reference comparison when using an unrestricted generic type. Actually, the compiler will use the best method it can find for the restricted type argument, but will look no further. For example, the code below will always print true, even when Test.test<B>(new B(), new B()) is called: class A { public static bool operator==(A x, A y) { return true; } } class B : A { public static bool operator==(B x, B y) { return false; } } class Test { void test<T>(T a, T b) where T : A { Console.WriteLine(a == b); } }

• When anyDensity=false why does getDrawingCache(true) return null?

  - by Robert Nekic

  First off, my application currently defines anyDensity=false in the manifest file. Elsewhere in the app, I'm trying to capture and display a View's DrawingCache but I'm not able to get a clear Bitmap without scaling artifacts. The code below yields a Bitmap but it has scaling artifacts and is generally fuzzy. myView.setDrawingCacheEnabled(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache()); myImageView.setImageBitmap(myBitmap); As I read it, the documentation for getDrawingCache says this is to be expected and to use getDrawingCache(true). Yet, both code examples below throw NullPointer exceptions because the Bitmap returned by getDrawingCache(true) is always null. myView.setDrawingCacheEnabled(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache(true)); myImageView.setImageBitmap(myBitmap); OR myView.buildDrawingCache(true); Bitmap myBitmap = Bitmap.Create(myView.getDrawingCache(true)); myImageView.setImageBitmap(myBitmap); myView.destroyDrawingCache(); Does anyone know how to properly capture and render the drawingCache when anyDensity=false?

• Creating an AJAX Searchable Database.

  - by Austin

  Currently I am using MySQLi to parse a CSV file into a Database, that step has been accomplished. However, My next step would be to make this Database searchable and automatically updated via jQuery.ajax(). Some people suggest that I print out the Database in another page and access it externally. I'm quite new to jquery + ajax so if anyone could point me in the right direction that would be greatly appreciated. I understand that the documentation on ajax should be enough to tell me what I'm looking for but it appears to talk only about retrieving data from an external file, what about from a mysql database? The code so far stands: <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> </head> <body> <input type="text" id="search" name="search" /> <input type="submit" value="submit"> <?php show_source(__FILE__); error_reporting(E_ALL);ini_set('display_errors', '1'); $category = NULL; $mc = new Memcache; $mc->addServer('localhost','11211'); $sql = new mysqli('localhost', 'user', 'pword', 'db'); $cache = $mc->get("updated_DB"); $query = 'SELECT cat,name,web,kw FROM infoDB WHERE cat LIKE ? OR name LIKE ? OR web LIKE ? OR kw LIKE ?'; $results = $sql->prepare($query); $results->bind_param('ssss', $query, $query, $query, $query); $results->execute(); $results->store_result(); ?> </body> </html>

• How to make Fluent NHibernate ignore Dictionary properties

  - by Matt Winckler

  I'm trying to make Fluent NHibernate's automapping ignore a Dictionary property on one of my classes, but Fluent is ignoring me instead. Ignoring other types of properties seems to work fine, but even after following the documentation and adding an override for the Dictionary, I still get the following exception when BuildSessionFactory is called: The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter. I've tried overriding by property name: .Override<MyClass>(map => { map.IgnoreProperty(x => x.MyDictionaryProperty); }) and also tried implementing ignores using a custom attribute, both of which result in the same exception from BuildSessionFactory. The only thing so far that makes this exception go away is removing the Dictionary property entirely. My question seems to be identical to this one which was never answered (though I'll expand the scope by stating it doesn't matter whether the dictionary is on an abstract base class; the problem always happens for me regardless of what class the property is on). Any takers this time around?

• Good resources for building web-app in Tapestry

  - by Rich

  Hi, I'm currently researching into Tapestry for my company and trying to decide if I think we can port our pre-existing proprietary web applications to something better. Currently we are running Tomcat and using JSP for our front end backed by our own framework that eventually uses JDBC to connect to an Oracle database. I've gone through the Tapestry tutorial, which was really neat and got me interested, but now I'm faced with what seems to be a common issue of documentation. There are a lot of things I'd need to be sure that I could accomplish with Tapestry before I'd be ready to commit fully to it. Does anyone have any good resources, be it a book or web article or anything else, that go into more detail beyond what the Tapestry tutorial explains? I am also considering integrating with Hibernate, and have read a little bit about Spring too. I'm still having a hard time understanding how Spring would be more useful than cumbersome in tandem with Tapestry,as they seem to have a lot of overlapping features. An example I read seemed to use Spring to interface with Hibernate, and then Tapestry to Spring, but I was under the impression Tapestry integrates to the same degree with Hibernate. The resource I'm speaking of is http://wiki.apache.org/tapestry/Tapstry5First_project_with_Tapestry5,_Spring_and_Hibernate . I was interested because I hadn't found information anywhere else on how to maintain user levels and sessions through a Tapestry application before, but wasn't exactly impressed by the need to use Spring in the example.

• Free solution for automatic updates with a .NET/C# app?

  - by a2h

  Yes, from searching I can see this has been asked time and time again. Here's a backstory. I'm an individual hobbyist developer with zero budget. A program I've been developing has been in need of constant bugfixes, and me and users are getting tired of having to manually update. Me, because my current solution of Manually FTP to my website Update a file "newest.txt" with the newest version Update index.html with a link to the newest version Hope for people to see the "there's an update" message Have them manually download the update sucks, and whenever I screw up an update, I get pitchforks. Users, because, well, "Are you ever going to implement auto-update?" "Will there ever be an auto-update feature?" Over the past I have looked into: WinSparkle - No in-app updates, and the DLL is 500 KB. My current solution is a few KBs in the executable and has no in-app updates. http://windowsclient.net/articles/appupdater.aspx - I can't comprehend the documentation http://www.codeproject.com/KB/vb/Auto_Update_Revisited.aspx - Doesn't appear to support anything other than working with files that aren't in use wyUpdate - wyBuild isn't free, and the file specification is simply too complex. Maybe if I was under a company paying me I could spend the time, but then I may as well pay for wyBuild. http://www.kineticjump.com/update/default.aspx - Ditto the last sentence. ClickOnce - Workarounds for implementing launching on startup are massive, horrendous and not worth it for such a simple feature. Publishing is a pain; manual FTP and replace of all files is required for servers without FrontPage Extensions. I'm pretty much ready to throw in the towel right now and strangle myself. And then I think about Sparkle... EDIT: I came across SparkleDotNET just then. Looks good, though the DLL is 200 KB. Don't know if that's really that big of an issue, though.

• Vimeo Desktop App OAuth

  - by Barry

  Hi Guys, I'm currently having massive trouble with Vimeo's Oauth implementation and my desktop app. My program does the following correctly. 1- Requests a Unauthorized Request Token with my key and secret and returns - a Token and a Token secret. 2- Generates a URL for the user to go to using the token which then shows our application's name and allows the user to Authorize us to use his/her account. It then shows a verifier which the user returns and puts into our app. The problem is the third step and actually exchanging the tokens for the access tokens. Basically every time we try and get them we get a "Invalid / expired token - The oauth_token passed was either not valid or has expired" I looked at the documentation and there's supposed to be a callback to a server when deployed like that which gives the user an "authorized token" but as im developing a desktop app we can't do this. So I assume the token retrieved in 1 is valid for this step. (actually it seems it is: http://vimeo.com/forums/topic:22605) So I'm wondering now am I missing something here on my actual vimeo application account now? is it treating it as a web hosted app with callbacks? all the elements are there for this to work and I've used this same component to create a twitter Oauth login in exactly the same way and it was fine. Thanks in advance, Barry

  Q1:I am using wxWidgets (C++) and have come accost a problem that i can not locate any help. I have created several wxTextCtrl boxes and would like the program to update the simple calculations in them when the user 'kills the focus.' I could not find any documentation on this subject on the wxWidgets webpage and Googling it only brought up wxPython. The two events i have found are: EVT_COMMAND_KILL_FOCUS - EVT_KILL_FOCUS for neither of which I could find any snippet for. Could anyone give me a short example or lead me to a page that would be helpful? Q2:Would i have to create an event to handle the focus being killed for each of my 8 wxTextCtrl boxes? In the case that i have to create a different event: How would i get each event to differentiate from each other? Will i have to create new wxID's for each of the wxTextCtrl boxes? class BasicPanel : public wxPanel { ... wxTextCtrl* one; wxTextCtrl* two; wxTextCtrl* three; wxTextCtrl* four; ... }

• Correct escaping of delimited identifers in SQL Server without using QUOTENAME

  - by Ross Bradbury

  Is there anything else that the code must do to sanitize identifiers (table, view, column) other than to wrap them in double quotation marks and "double up" and double quotation marks present in the identifier name? References would be appreciated. I have inherited a code base that has a custom object-relational mapping (ORM) system. SQL cannot be written in the application but the ORM must still eventually generate the SQL to send to the SQL Server. All identifiers are quoted with double quotation marks. string QuoteName(string identifier) { return "\" + identifier.Replace("\"", "\"\"") + "\""; } If I were building this dynamic SQL in SQL, I would use the built-in SQL Server QUOTENAME function: declare @identifier nvarchar(128); set @identifier = N'Client"; DROP TABLE [dbo].Client; --'; declare @delimitedIdentifier nvarchar(258); set @delimitedIdentifier = QUOTENAME(@identifier, '"'); print @delimitedIdentifier; -- "Client""; DROP TABLE [dbo].Client; --" I have not found any definitive documentation about how to escape quoted identifiers in SQL Server. I have found Delimited Identifiers (Database Engine) and I also saw this stackoverflow question about sanitizing. If it were to have to call the QUOTENAME function just to quote the identifiers that is a lot of traffic to SQL Server that should not be needed. The ORM seems to be pretty well thought out with regards to SQL Injection. It is in C# and predates the nHibernate port and Entity Framework etc. All user input is sent using ADO.NET SqlParameter objects, it is just the identifier names that I am concerned about in this question. This needs to work on SQL Server 2005 and 2008.
