• Yet Another crosdomain.xml question or: "How to interpret documentation correctly"

  - by cboese

  Hi! I have read a lot about the new policy-policy of flash player and also know the master policy file. Now image the following situation: There are two servers with services (http) running at custom ports servera.com:2222/websiteA serverb.com:3333/websiteB Now I open a swf from server a (eg. servera.com:2222/websiteA/A.swf) that wants to access the service of serverb. Of course I need a crossdomain.xml at the right place and there are multiple variations possible. I dont want to use a master policy file, as I might not have control over the root of both servers. One solution I found works with the following crossdomain: <?xml version="1.0"?> <cross-domain-policy> <allow-access-from domain="*"/> </cross-domain-policy> served at serverb.com:3333/websiteB/crossdomain.xml So now for my question: Is it possible to get rid of the "*" and use a proper (not as general as *) domainname in the allow-access-from rule? All my attempts failed, and from what I understand it should be possible.

• How to set QNetworkReply properties to get correct NCBI pages?

  - by Claire Huang

  I try to get this following url using the downloadURL function: http://www.ncbi.nlm.nih.gov/nuccore/27884304 But the data is not as what we can see through the browser. Now I know it's because that I need to give the correct information such as browser, how can I know what kind of information I need to set, and how can I set it? (By setHeader function??) In VC++, we can use CInternetSession and CHttpConnection Object to get the correct information without setting any other detail information, is there any similar way in Qt or other cross-platform C++ network lib?? (Yes, I need the the cross-platform property.) QNetworkReply::NetworkError downloadURL(const QUrl &url, QByteArray &data) { QNetworkAccessManager manager; QNetworkRequest request(url); request.setHeader(QNetworkRequest::ContentTypeHeader ,"Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7 (.NET CLR 3.5.30729)"); QNetworkReply *reply = manager.get(request); QEventLoop loop; QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit())); loop.exec(); QVariant statusCodeV = reply->attribute(QNetworkRequest::RedirectionTargetAttribute); QUrl redirectTo = statusCodeV.toUrl(); if (!redirectTo.isEmpty()) { if (redirectTo.host().isEmpty()) { const QByteArray newaddr = ("http://"+url.host()+redirectTo.encodedPath()).toAscii(); redirectTo.setEncodedUrl(newaddr); redirectTo.setHost(url.host()); } return (downloadURL(redirectTo, data)); } if (reply->error() != QNetworkReply::NoError) { return reply->error(); } data = reply->readAll(); delete reply; return QNetworkReply::NoError; }

• YUI "Get" utility to parse JSON response?

  - by Sean

  The documentation page for the YUI "Get" utility says: Get Utility is ideal for loading your own scripts or CSS progressively (lazy-loading) or for retrieving cross-domain JSON data from sources in which you have total trust. ...but doesn't have any actual examples for how to do so. Their one example doesn't actually request a JSON document from a remote server, but instead a document containing actual JavaScript along with the JSON data. I'm just interested in the JSON response from the Google Maps API HTTP (REST) interface. Because I can't do cross-site scripting with the "Connect" utility, I am trying the "Get" utility. But merely inserting some JSON data into the page isn't going to do anything, of course. I have to assign it to a variable. But how? Also, just inserting JSON data into the page makes Firefox complain that there's a JavaScript error. And understandably! Plain ol' JSON data isn't going to parse as valid JavaScript. Any ideas?

• JS sort works in Firefox but not IE - can't work out why

  - by Max Williams

  I have a line in a javascript function that sort an array of objects based on the order of another array of strings. This is working in firefox but not in IE and i don't know why. Here's what my data looks like going into the sort call. (I'm using an array of three items just to illustrate the point here). //cherry first then the rest in alphabetical order originalData = ['cherry','apple','banana','clementine','nectarine','plum'] //data before sorting - note how clementine is second item - we wan to to to be after apple and banana csub = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] //after sorting, csub has been rearranged but still isn't right: clementine is before banana csubSorted = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] Here's the actual sort code: csubSorted = csub.sort(function(a,b){ return (originalData.indexOf(a.value) > originalData.indexOf(b.value)); }); Can anyone see why this wouldn't work? Is the basic javascript sort function not cross-browser compatible? Can i do this a different way (eg with jquery) that would be cross-browser? grateful for any advice - max

• SEO: Where do I start?

  - by James

  Hi, I am primarily a software developer however I tend to delve in some web development from time to time. I have recently been asked to have a look at a friends website as they are wanting to improve their position in search engine results i.e. google/yahoo etc. I am aware there is no guarentee that their position will change, however, I do know there are techniques/ways to make your website more visible to search engine spiders and to consequently improve your position in the rankings i.e. performing SEO. Before I started looking at the SEO of the site I did the following prerequsite checks: Ran the website through the W3C Markup Validator and the W3C CSS Validator services. Looked through the markup code manually (check for meta tags etc) Performed a thorough cross browser compatibility test. From those checks, the following was evident: No SEO has been performed on the site before. The website has been developed using a visual editing tool such as dreamweaver (as it failed the validation services miserably and tables where being used everywhere!) The site is fairly cross browser compatibile (only some slight issues with IE8 which are easily resolved). How the site navigation is, isn't very search engine friendly (e.g. index.php?page=home) I can see right away a major improvement for SEO (or I at least think) would be to change the way the website is structured i.e. change from using dynamic pages such as "index.php?page=home" and actually having pages called "home.html". Other area's would be to add meta tags to identify keywords, and then sprinkling these keywords over the pages. As I am a rookie in this department, could anyone give me some advice on how I could perform thorough SEO on this website? Thanks in advance.

• VB.net httpwebrequest For loop hangs every 10 or so iterations

  - by user574632

  Hello, I am trying to loop through an array and perform an httpwebrequest in each iteration. The code seems to work, however it pauses for a while (eg alot longer than the set timeout. Tried setting that to 100 to check and it still pauses) after every 10 or so iterations, then carries on working. Here is what i have so far: For i As Integer = 0 To numberOfProxies - 1 Try 'create request to a proxyJudge php page using proxy Dim request As HttpWebRequest = HttpWebRequest.Create("http://www.pr0.net/deny/azenv.php") request.Proxy = New Net.WebProxy(proxies(i)) 'select the current proxie from the proxies array request.Timeout = 10000 'set timeout Dim response As HttpWebResponse = request.GetResponse() Dim sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If Catch ex As Exception 'MessageBox.Show(ex.ToString) used in testing UpdateListbox(ListBox4, proxies(i)) End Try completedProxyCheck += 1 lblTotalProxiesChecked.CustomInvoke(Sub(l) l.Text = completedProxyCheck) Next I have searched all over this site and via google, and most responses to this type of question say the response must be closed. I have tried a using block, eg: Using response As HttpWebResponse = request.GetResponse() Using sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If End Using End Using And it makes no difference (though i may have implemented it wrong) As you can tell im very new to VB or any OOP so its probably a simple problem but i cant work it out. Any suggestions or just tips on how to diagnose these types of problems would be really appreciated.

• How to get node without children in xQuery?

  - by mbrevoort

  So I have two nodes of elements that I'm essentially trying to join. I want the top level node to stay the same but the child nodes to be replaced by those cross referenced. Given: <stuff> <item foo="foo" boo="1"/> <item foo="bar" boo="2" /> <item foo="baz" boo="3"/> <item foo="blah boo="4""/> </stuff> <list a="1" b="2"> <foo>bar</foo> <foo>baz</foo> </list> I want to loop through "list" and cross reference elements in "stuff" for this result: <list a="1" b="2"> <item foo="bar" boo="2" /> <item foo="baz" boo="3"/> </list> I want to do this without having to know about what attributes might be on "list". In other words I don't want to have to explicitly call them out like attribute a { $list/@a }, attribute b { $list/@b }

• Chrome: Dynamically created <style> tag does not have content?

  - by Shizhidi

  Hello. I encountered a weird problem when trying to write a cross-browser script. Basically my header looks like this <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> </head> Then in the body tag: <p id="hey">Hey</p> <input type="button" value="attachStyle" name="attachStyle" onclick="attachStyle();"></input> <script> function attachStyle() { var strVar=""; strVar += "<style type='text\/css'>#hey {border:5px solid red;}<\/script>"; $("head").append(strVar); } </script> The button works in Firefox, but not in Chrome. When I looked at the html DOM elements in the developer tool, the style tag was inserted but without content, like this: <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <style type='text/css'></script> </head> I'm curious as to what causes this? And how to create CSS style in a way that is cross-browser? Thanks!

• Endianness and C API's: Specifically OpenSSL.

  - by Hassan Syed

  I have an algorithm that uses the following OpenSSL calls: HMAC_update() / HMAC_final() // ripe160 EVP_CipherUpdate() / EVP_CipherFinal() // cbc_blowfish These algorithm take a unsigned char * into the "plain text". My input data is comes from a C++ std::string::c_str() which originate from a protocol buffer object as a encoded UTF-8 string. UTF-8 strings are meant to be endian neutrial. However I'm a bit paranoid about how OpenSSL may perform operations on the data. My understanding is that encryption algorithms work on 8-bit blocks of data, and if a unsigned char * is used for pointer arithmetic when the operations are performed the algorithms should be endian neutral and I do not need to worry about anything. My uncertainty is compounded by the fact that I am working on a little-endian machine and have never done any real cross-architecture programming. My beliefs/reasoning are/is based on the following two properties std::string (not wstring) internally uses a 8-bit ptr and a the resulting c_str() ptr will itterate the same way regardless of the CPU architecture. Encryption algorithms are either by design, or by implementation, endian neutral. I know the best way to get a definitive answer is to use QEMU and do some cross-platform unit tests (which I plan to do). My question is a request for comments on my reasoning, and perhaps will assist other programmers when faced with similar problems.

• Silverlight ClientAccessPolicy issue...I think

  - by Terrence

  Fisrt of all I have my ClientAccessPolicy.xml file in the root of my website. If I access my website using the public domain name like this: h t t p://www.mydomain.com and then go to the page where my SL control is, I get the spinning % numbers up until about 98%, then it quits and my SL control does not appear on the page. If I access my website using the machine name (website is at datacenter, we have vpn setup) like this: h t t p://machinename and then go to the page where my SL control is everything works fine. this must be a ClientAccess Policy issue don't your think? Or what DO you thnik the issue is? Thanks in advance. Here is the contents of my ClientAccessPolicy.xml file: <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*" /> </allow-from> <grant-to> <resource path="/" include-subpaths="true" /> </grant-to> </policy> </cross-domain-access> </access-policy>

• Alternative to using c:out to prevent XSS

  - by lynxforest

  I'm working on preventing cross site scripting (XSS) in a Java, Spring based, Web application. I have already implemented a servlet filter similar to this example http://greatwebguy.com/programming/java/simple-cross-site-scripting-xss-servlet-filter/ which sanitizes all the input into the application. As an extra security measure I would like to also sanitize all output of the application in all JSPs. I have done some research to see how this could be done and found two complementary options. One of them is the use of Spring's defaultHtmlEscape attribute. This was very easy to implement (a few lines in web.xml), and it works great when your output is going through one of spring's tags (ie: message, or form tags). The other option I have found is to not directly use EL expressions such as ${...} and instead use <c:out value="${...}" /> That second approach works perfectly, however due to the size of the application I am working on (200+ JSP files). It is a very cumbersome task to have to replace all inappropriate uses of EL expressions with the c:out tag. Also it would become a cumbersome task in the future to make sure all developers stick to this convention of using the c:out tag (not to mention, how much more unreadable the code would be). Is there alternative way to escape the output of EL expressions that would require fewer code modifications? Thank you in advance.

• Crosstab with multiple items

  - by Michael Wexler

  In SPSS, it is (relatively) easy to create a cross tab with multiple variables using the factors as the table heading. So, something like the following (made up data, etc.). Q1, Q2, and Q3 each have either a 1, a 2, or a 3 for each person. 1 (very Often) 2 (Rarely) 3 (Never) Q1. Likes it 12 15 13 Q2. Recommends it 22 11 10 Q3. Used it 22 12 9 In SPSS, one can even request row, column, or total percentages. I've tried table(), ftable(), xtab(), CrossTable() from gmodels, and CrossTable() from descr, and none of these can handle (afaik) multiple variables; they mostly seem to handle 1 variable crossed with another variable, and the 3rd creates layers. Is there a package with some good cross tabbing/table examples that I could use to figure this out? I'm sure I'm missing something simple, so I appreciate you pointing out what I missed. Perhaps I have to generate each row as a separate list and then make a dataframe and print the dataframe?

• CSS Clearing Floats

  - by Frank

  I'm making more of an effort to separate my html structure from presentation, but sometimes when I look at the complexity of the hacks or workarounds to make things work cross-browser, I'm amazed at huge collective waste of productive hours that are put into this. As I understand it, floats were never created for creating layouts, but because many layouts need a footer, that's how they're often being used. To clear the floats, you can add an empty div that clears both sides (div class="clear"). That is simple and works cross browser, but it adds "non-semantic" html rather than solving the presentation problem within the CSS. I realize this, but after looking at all of the solutions with their benefits and drawbacks, it seems to make more sense to go with the empty div (predictable behavior across browsers), rather than create separate stylesheets, including various css hacks and workarounds, etc. which would also need to change as CSS evolves. Is it o.k. to do this as long as you do understand what you're doing and why you're doing it? Or is it better to find the CSS workarounds, hacks and separate structure from presentation at all costs, even when the CSS presentation tools provided are not evolved to the point where they can handle such basic layout issues?

• gluLookAt alternative doesn't work

  - by Brammie

  Hey guys. I'm trying to calculate a lookat matrix myself, instead of using gluLookAt(). My problem is that my matrix doesn't work. using the same parameters on gluLookAt does work however. my way of creating a lookat matrix: Vector3 Eye, At, Up; //these should be parameters =) Vector3 zaxis = At - Eye; zaxis.Normalize(); Vector3 xaxis = Vector3::Cross(Up, zaxis); xaxis.Normalize(); Vector3 yaxis = Vector3::Cross(zaxis, xaxis); yaxis.Normalize(); float r[16] = { xaxis.x, yaxis.x, zaxis.x, 0, xaxis.y, yaxis.y, zaxis.y, 0, xaxis.z, yaxis.z, zaxis.z, 0, 0, 0, 0, 1, }; Matrix Rotation; memcpy(Rotation.values, r, sizeof(r)); float t[16] = { 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, -Eye.x, -Eye.y, -Eye.z, 1, }; Matrix Translation; memcpy(Translation.values, t, sizeof(t)); View = Rotation * Translation; // i tried reversing this as well (translation*rotation) now, when i try to use this matrix be calling glMultMatrixf, nothing shows up in my engine, while using the same eye, lookat and up values on gluLookAt works perfect as i said before. glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glMultMatrixf(View); the problem must be in somewhere in the code i posted here, i know the problem is not in my Vector3/Matrix classes, because they work fine when creating a projection matrix.

• How can I debug a session

  - by Organ Grinding Monkey

  I have been asked to work of a very large web application and deploy it. The problem that I'm facing here is that when I deploy the application and more that 1 user logs into the system, the sessions seem to cross over i.e: Person A logs in and works on the site, all good. When person B logs in, person A will then be logged in as person B as well. I have been asked to work of a very large web application and deploy it. The problem that I'm facing here is that when I deploy the application and more that 1 user logs into the system, the sessions seem to cross over i.e: Person A logs in and works on the site, all good. When person B logs in, person A will then be logged in as person B as well. If anyone has experienced this behaviour before and can steer me in the right direction, that would be first prize, Second prize would be to show me how I can debug this situation so that I can find out where the problem is and fix it. Some information about the application. From what I've been told and what I've seen within the app is that it started as a .Net 1.1 application and got upgraded to .Net 2 and that's why the log in system was done the way it is. (The application is huge and now complete and that's why I cant rewrite the whole user authentication process, it will just take to long and I don't know what effect it might have) All the Logged in User information is stored in properties that have been added in the Global.asax.vb file. (could this be the problem?) Any help here would be greatly appreciated

• Qt/C++ Error handling

  - by ShiGon

  I've been doing a lot of research about handling errors with Qt/C++ and I'm still as lost as when I started. Maybe I'm looking for an easy way out (like other languages provide). One, in particular, provides for an unhandled exception which I use religiously. When the program encounters a problem, it throws the unhandled exception so that I can create my own error report. That report gets sent from my customers machine to a server online which I then read later. The problem that I'm having with C++ is that any error handling that's done has to be thought of BEFORE hand (think try/catch or massive conditionals). In my experience, problems in code are not thought of before hand else there wouldn't be a problem to begin with. Writing a cross-platform application without a cross-platform error handling/reporting/trace mechanism is a little scary to me. My question is: Is there any kind of Qt or C++ Specific "catch-all" error trapping mechanism that I can use in my application so that, if something does go wrong I can, at least, write a report before it crashes?

• Doctrine: How to traverse from an entity to another 'linked' entity?

  - by ropstah

  I'm loading 3 different tables using a cross-join in Doctrine_RawSql. This brings me back the following object: User -> User class (doctrine base class) Settings -> DoctrineCollection of Setting User_Settings -> DoctrineCollection of User_Setting The object above is the result of a many-to-many relationship between User and Setting where User_Setting acts as a reference table. User_Setting also contains another field named value. This obviously contains the value of the corresponding Setting. All good so far, however the Settings and User_Settings properties of the returned User object are in no way linked to each other (apart from the setting_id field ofcourse). Is there any direct way to traverse directly from the Settings property to the corresponding User_Settings property? This is the corresponding query: $sets = new Doctrine_RawSql(); $sets->select('{us.*}, {s.*}, {uset.*}') ->from('(User us CROSS JOIN Setting s) LEFT JOIN User_Setting uset ON us.user_id = uset.user_id AND s.setting_id = uset.setting_id') ->addComponent('us', 'User us') ->addComponent('uset', 'us.User_Setting uset') ->addComponent('s', 'us.Setting s') ->where('s.category_id = ? AND us.usr_auto_key = ?',array(1, 1)); $sets = $sets->execute();

• is there a signal emiter/consumer engine (like in Django) for .NET (C#)

  - by user118657

  Has .NET (C#) anything like Django's Signals engine? Our business logic become really complicated over few years of adding new features. I'm going to re-architecture it. Currently all features are very coupled that makes regression errors while changing something one one place - some other place may be broken. I really like Django's apps idea where separate applications introduce new functionality and are absolutely separate. Communication between apps is implemented though signals. I wounder if there is something in .NET that allows to divide project business to many separated "apps" (plug-ins, zones, modules, you name it) and make communication using some kind of "signals". For example we have simple order flow. We can add "coupon app" that if exists in the project adds abilities to use discount coupon. We can add "cross sale" module that if exists adds abilities to offer cross-sale products Email notification module that if exists adds abilities to send order email notifications. But in the same time all this modules are "self-contained" means that communication between them is done using emitting signals (ORDER_PROCCESS_START, ORDER_SUCCESS, etcs) and other modules can subscribe to this signals and process them in required way. This architecture is not related to web, all business logic is processed on the server side like without working with HTTP directly. I wonder if it's good architecture from code maintaining and testing point of few, is it possible to do this in .NET? Any drawbacks that I don't realize now?

• XNA, C# - Check if a Vector2 path crosses another Vector2 path.

  - by Nick

  Hello all, I have an XNA question for those with more experience in these matters than myself (maths). Background: I have a game that implements a boundary class, this simply hosts 2 Vector2 objects, a start and an end point. The current implementation crudely handles collision detection by assuming boundaries are always vertical or horizontal, i.e. if start.x and end.x are the same check I am not trying to pass x etc. Ideally what I would like to implement is a method that accepts two Vector2 parameters. The first being a current location, the second being a requested location (where I would like to move it to assuming no objections). The method would also accept a boundary object. What the method should then do is tell me if I am going to cross the boundry in this move. this could be a bool or ideally something representing how far I can actually move. This empty method might explain better than I can in words. /// <summary> /// Checks the move. /// </summary> /// <param name="current">The current.</param> /// <param name="requested">The requested.</param> /// <param name="boundry">The boundry.</param> /// <returns></returns> public bool CheckMove(Vector2 current, Vector2 requested, Boundry boundry) { //return a bool that indicated if the suggested move will cross the boundry. return true; }

• Programmable Home Security Alarm [closed]

  - by stej

  I don't ask for recommendation! (just wanted to say that; anyway it doesn't matter now as the question is closed) I've seen some advertisements about home alarms that notifies me that something is happening in my house. None of them mentioned programmability (with real programming language like e.g C, assembler, whatever). As a programmer I'd like to have a possibility to add some behaviour, that is not part of the alarm itself. This might be: take snapshots of all cameras in a house and send it to some email send email, twitter message, skype message to some predefined account send email to a police (silly, I know) start turning the lights on and off (scary, right?) etc. (would be veeery challenging with assembler, I know; but lets suppose I can use some more high level language) I don't expect that there is a alarm system capable of this stuff, that's why I'm looking for a programmable module. Question: Is it even possible? Is it good idea (my program could crash and cause instability of the system).

• How do Opera's keyboard shortcut settings work?

  - by zem

  Firefox 4 beta is starting to freeze up the way Firefox 3 used to on my machine, and I want a browser that'll play gifs at full speed, so on a Mac my only other choice seems to be Opera. There are just two issues I have with it right now: one, the scrolling is weird compared to every other Mac application, but I can get used to that if there's no way to fix it. Two, cmd-1 through cmd-9 activate the "speed dial" bookmarks instead of selecting tabs 1-9, like in Firefox and Chrome. I can disable those shortcuts easily enough, so I don't keep accidentally loading a different page when I instinctively try to do that, but in an ideal world I could remap those commands to do what I want. The keyboard shortcut editor is weird: There seems to be a scrappy little language for associating actions with commands. It has some limited autocompletion when you type stuff in, and I couldn't find a "select specific tab" action, but some of the existing commands are complicated enough that I'd be surprised if there's not a way to do it. Is there documentation for this language anywhere? Clicking "help" just brings me to this page, which is not very helpful.

• Is there a setting in Exchange Server 2007 that we can set to make these headers propogate and be received by a POP/IMAP client?

  - by Ruruboy

  When using EWS Managed API to send Email via Exchange Server 2007. I noticed that MAPI clients like MS Outlook display all custom headers. But when I use POP3/IMAP clients like MS Outlook Express. I have noticed that these custom headers do not display in the message opened from MS Outlook Express. Is there a setting in Exchange Server 2007 that we can set to make these custom headers propagate and be received by a POP/IMAP client? Also why do custom headers in example below display up in lower case in MAPI clients like MS Outlook? But surprisingly if we use SMTPClient class to send email then these headers display as sent with Case Sensitive letters. eg. Header.

• Change the Default Date setting in Word 2010

  - by Chris

  I am using Word 2010 and Windows 7. You know how when you start typing a date in Word it will automatically suggest what it thinks you want? Like if I start typing “6/29”, a little grey bubble will display “6/29/13 (Press ENTER to Insert)”. How do I get it so the bubble will display the year in a 4 digit format, such as "6/29/2013 (Press Enter to Insert)"? The below picture is how it looks when typing a date into Word. I have already gone to the Date & Time option under the Insert menu and the date format that I want is already selected. I think this is only for using quickparts anyway, so the date automatically updates when you open a document. The Region and Language settings under the Control Panel are correct as well. I thought at one point I found it somewhere under options, but I am sure I looked through everything many times and I can’t find it. I posted this exact question at the Microsoft website and someone replied: Go to the Windows Control Panel and click on Clock, Language and Region and then on Change the date, time, or number format and then modify the Short date format so that it is what you want to be used. So please don't suggest this again, because in my question I did say that I already tried this and it doesn't work, at least not for Word, in this situation. Thanks.
