• .NET DataGridView rows' default alignment all set to left

  - by Xster

  DataGridView gets bound to DataTable. I then try to set some columns' DefaultCellStyle.Alignment to right. It doesn't work. After a bunch of tinkering, it turns out that every single row's DefaultCellStyle.Alignment is set to left and overrides it. DataGridView.DefaultCellStyle or RowsDefaultCellStyle doesn't do anything. Makes sense since a particular row's DefaultCellStyle is more specific but what gives. Why are they all set to something and not NotSet? How do I get rid of it instead of iterating through all rows?

• mysql C connector unresolved symbols on Win2k8 but not on XP?

  - by jimmy glick

  I have a visual C++ 2008 express project which compiles fine on Windows XP with mysql C connector 6.0.2. When I copy the project over to a Windows Server 2008 x64 machine, it gets a bunch of linker errors like "unresolved external symbol _mysql_server_end@0" "unresolved external symbol _mysql_close@4" "unresolved external _mysql_real_connect@32". Is the mysql C connector 6.0.2 known to not work with Win Server 2008? (Note, the C connector is installed into the same place on both machines, and since I just copied over the project wholesale, it still has the correct libmysql.lib include. The interesting thing is that the errors I get on XP if I remove the libmysql.lib are not the same errors I'm getting on Win2k8, so that's what makes me think it might be an incompatibility...or maybe it's just because win2k8 is x64 and XP is x86?) Thanks

• How do you perform macro expansion within #ifdef?

  - by Malvineous

  Hi all, I have some fairly generic code which uses preprocessor macros to add a certain prefix onto other macros. This is a much simplified example of what happens: #define MY_VAR(x) prefix_##x "prefix_" is actually defined elsewhere, so it will be different each time the file is included. It works well, but now I have some code I would like to skip if one of the tokens doesn't exist, but this doesn't work: #if defined MY_VAR(hello) What I want it to expand to is this: #ifdef prefix_hello But I can't figure out how. I need to use the MY_VAR() macro to do the expansion, so I can't just hardcode the name. (It's actually for some testing code, the same code gets included with a different prefix each time to test a bunch of classes, and I want to skip a couple of tests for a handful of the classes.) Is this possible with the C++ preprocessor?

• Voice Communication over TCP/IP

  - by Micha

  Hello, I'm currently developing application using DirectSound for communication on an intranet. I've had working solution using UDP but then my boss told me he wants to use TCP/IP for some reason. I've tried to implement it in pretty much the same way as UDP, but with very little success. What I get is basically just noise. 20% of it is the recorded sound and the rest is just weird noise. My guess for the reason is that TCP needs to read all the accepted data several times until it gets the final sound I can play. Now two questions: Am I on the right tracks? Is it even good idea to use TCP/IP for this kind of application (voice conferencing of sorts)? I'm doing it in C# but I don't think this is language specific.

• TinyMCE converts &lt;xxx&gt; into <xxx></xxx> - how do I stop it?

  - by Petras

  I can successfully save the characters < and . I do this with these options: entities : """ cleanup : false verify_html : false So far no problems. However, whenever I put anything between that text it gets converted into a tag: &lt;xxx&gt; converts to <xxx></xxx> How do I stop that?I am trying to enter sample HTML into TinyMCE so I can document some XML. There must be a standard way of doing this I imagine.

• ASP.NET aspxerrorpath in URL

  - by theog

  I have a site where I use CustomErrors in the web.config to specify a custom error page, and that's working just fine. The custom 404 page is also specified in the IIS configuration (because if it's not, I don't get my custom 404 page). But I have some logic that kicks in if a user gets a 404 that looks at their requested URL and make a navigation suggestion, if appropriate. This logic relies on the aspxerrorpath value. On my development PC, the aspxerrorpath is correctly appended to the URL, like so: http://localhost:3092/FileNotFound.aspx?aspxerrorpath=/badpage.aspx, but on my test site, there's no aspxerrorpath appended to the URL, so all of my custom logic is bypassed and my suggestions don't work. I'm not sure if this is an IIS config issue or something else. The web server is Windows Server 2008 with IIS 7. Any thoughts? Many Thanks.

• Avoid implicit conversion from date to timestamp for selects with Oracle using Hibernate

  - by sapporo

  I'm using Hibernate 3.2.7.GA criteria queries to select rows from an Oracle Enterprise Edition 10.2.0.4.0 database, filtering by a timestamp field. The field in question is of type java.util.Date in Java, and DATE in Oracle. It turns out that the field gets mapped to java.sql.Timestamp, and Oracle converts all rows to TIMESTAMP before comparing to the passed in value, bypassing the index and thereby ruining performance. One solution would be to use Hibernate's sqlRestriction() along with Oracle's TO_DATE function. That would fix performance, but requires rewriting the application code (lots of queries). So is there a more elegant solution? Since Hibernate already does type mapping, could it be configured to do the right thing? Update: The problem occurs in a variety of configurations, but here's one specific example: Oracle Enterprise Edition 10.2.0.4.0 Oracle JDBC Driver 11.1.0.7.0 Hibernate 3.2.7.GA Hibernate's Oracle10gDialect Java 1.6.0_16

• jqueryForm and empty uploads

  - by Aiden Bell

  Hi All, Been scratching my head for too long on this: Using jquery.form, (http://malsup.com/jquery/form) with PHP ... my $_FILES['someimage'] gets set but the error number is always UPLOAD_ERR_NO_FILE, size is also 0. The JavaScript: $('form input[type=file]').change(function(){ $(this).clone().appendTo('#imgform'); $('#imgform').ajaxForm(); $('#imgform').ajaxSubmit( { type:'POST' } ); }); Which appends to: <form id="imgform" method="POST" action="/api/images.php" enctype="multipart/form-data"></form> From another form which has bog-standard file inputs. PHP logs are clean, but var_dumping $_FILES always shows that the index is set to the name of the form element ... but no data. Thanks guys! (Sorry, I know jQuery-like questions are too frequent round these parts).

• Unable to resolve user environment variable correctly

  - by Junaid

  I am trying to resolve %USERPROFILE% using WScript.Shell. When I create a vbs file and run directly from Windows, I get the correct path for the logged-in user C:\Documents and Settings\Administrator but it gets resolved to C:\Documents and Settings\Default User instead of logged-in user when I used it inside my classic ASP webapp running on the local machine on IIS. The code I used is as below var oShell = new ActiveXObject("Wscript.Shell"); var userPath = oShell.ExpandEnvironmentStrings("%USERPROFILE%"); Is there a permission/setting which I need to check to get correct value of USERPROFILE when retrieving value from the webapp? PS: I am using javascript to code.

• problem with closing sockets

  - by Samantha

  Hi, I'm trying to write a client/server program with threads. I close the socket once the connexion is finished. The servers gets plenty of new connexions, and the socket number (file descriptor) increases very quickly: after 5 minutes running I was already at around file descriptor number 800! Is this a normal thing? Do threads share file descriptors? When I do close(sockfd); is the number released immediatly or after a some time? PS: I used to do with fork(), and I didn't have this issue. Thanks

• Bitmap files added in .rc not listed in resource.h

  - by ame

  I added a large number of bitmap files to my MFC project in resource view (Visual Studio). However, the resource.h file does not list any of these files. I would want them to be listed with exactly the same name as they are added in .rc bitmap list (say the name is xxx) I want it listed as #define IDB_xxx If I try to click on the bitmap in the .rc list and import it, it gets listed as IDB_BITMAP1. Owing to the large number of files it is not feasible for me to manually rename them for use in my code.

• Remove innerHTML from div

  - by coffeeaddict

  I'm trying to clear the div's innerHTML before repopulating it. I tried removeData() but once that's called, when I try to add the data, I get nothing from the next line after remove whereas if I remove the removeData() it's fine again. I just want to clear out any previous content in that div before I re-populate it. divToUpdate.removeData(); //clean out any existing innerHTML div content first divToUpdate.html(data); It looks like it never gets to my divToUpdate.html(data) for some reason after it calls that removeData();

• How to control Time zone formatting in System.Xml.Serialization or during application execution?

  - by Beal

  I'm developing a C# .Net Application that is executing on a system located in the Central Time Zone. The application gets information from a third party using an API they provide. I have used the WSDL to produce the code that my application access the API with...their reporting API allows you to define a start date and end date for the report. These are C# DateTime fields and XSD:dateTime. Now when I set the start date and end dates and allow the API to create the SOAP messages the dates don't always include a Time Zone unless I set the date fields using the ToLocalTime method; however, the method will create the DateTime fields in the Central Time Zone (CST) but I need to have it create these fields in the Pacific Time Zone (PST). If I set my machine time to PST all is good...but of course that causes other time issues. What methods can I use to control the formatting of the DateTime? Alternatively, is there a application setting that can be set in C# that allows timezone control?

• Can't append space at end of UITextView

  - by Sam V

  I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have the UITextView text property ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this? I tried using the \s char and no success.

• ASP MVC 2: Regular expression attribute working on clientside but not on serverside

  - by wh0emPah

  [Required(ErrorMessage = "Date is required")] [RegularExpression(@"^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((1[6-9]|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((1[6-9]|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((1[6-9]|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$", ErrorMessage="Date is not valid must be like (dd/mm/jjjj)")] public DateTime Startdate{ get; set;} The client-side validation works perfectly. So it seems that JavaScript can successfully understand my regular expression. But when I do a postback, and the modelstate.Isvalid() gets called. My date isn't valid anymore. So I'm guessing that when .NET performs the matching with the regEx it doesn't match. My question: Why does this regular expression match on the client side but not on the server side?

• Spring 3 MVC - how to turn a form into a query string?

  - by caerphilly

  I have a simple Spring form that gets bound to a form object on post. The http POST handler does some work, and then needs to redirect to a new URL, passing the form data as querystring parameters. So, assuming I have a form backing object with properties "param1" and "param2", I want to build a string that looks something like this: redirect:/app/new/page?param1=value;param2=value Now, Spring will automatically bind values FROM a querystring or a form post into my form object, but I want to GENERATE a querystring with values taken from the form object. Obviously it's trivial to do this manually but since I'm going to have lots of different form backing objects, is there some built-in facility in Spring to generate a query string from a form object, suitable for building into a URL? Thanks.

• Materialized Query Table in SQL Server 2005

  - by Azho KG

  In DB2 there is a support for Materialized Query Table (MQT). Basicly you write a query and create a MQT. But the difference from View is that the query is pre-executed and resulting data is stored in MQT and there are some options when to refresh/syncronize the MQT with base tables. I want same functionality in SQL Server. Is there a way to achieve same result? I've tables with millions of rows, and I want to show summary (like total # of members, total expense and etc) in dashboard. So I don't want to count every time user gets to dashboard, instead I want to store them in table and I want that table to be refresh each night. Any kind of hints, answers,suggestions and ideas are welcome. Thanks.

• Odd Series of Packets, How would I reproduce this behavior?

  - by JustSmith

  I recorded a series of http packets that I cant programmatically recreate. The series of packets goes like this: HTTP GET /axis-cgi/admin/param.cgi?action=list&group=Network.eth0.MACAddress,Properties.System.SerialNumber,DVTelTest,SightLogix.ProdShortName HTTP/1.1 HTTP HTTP/1.1 200 OK (text/plain) HTTP GET /axis-cgi/admin/param.cgi?action=list&group=Properties.Image.Resolution HTTP/1.1 HTTP HTTP/1.1 200 OK (text/plain) HTTP GET /axis-cgi/admin/param.cgi?action=update&Network.RTSP.ProtViewer=password HTTP/1.1 HTTP GET /axis-cgi/admin/param.cgi?action=list&group=Event HTTP/1.1 HTTP HTTP/1.1 200 OK (text/plain) HTTP GET /axis-cgi/admin/param.cgi?action=list&group=ImageSource.I0.Sensor HTTP/1.1 HTTP HTTP/1.1 200 OK (text/plain) Notice the two GET followed by one response. I though the two gets were going out at the same time but there is no corresponding number of responses. Also when trying to reproduce this pattern as the server if I abort the first GET request the client waits until it times out and starts the request over with out sending any other requests. What is happening here? How can I reproduce it?

• Handling dynamic data from javascript or rails

  - by 99miles

  I have page consisting of a calendar view ( http://code.google.com/p/calendardateselect/ ) as well as divs, each of which contain information about a person. In each div I want to have a link to a new controller and action, and pass the id for the person and the date selected in the calendar. I can think of a one way, but I'm thinking there's likely a better solution: 1) Do something like: =link_to_function "Week", "weekClicked(#{person.id})" Then in the weekClicked() javascript method I get the selected date from the calendar, such as: $('e_date').selected_date; then with javascript I could make a post request as mentioned here: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit 2) Or, is there a way that I could make each link a button in it's own form and maybe have a hidden field that gets the selected date from the calendar as or before the form is submitted? I tried this too, but couldn't figure it out. This definitely seems like it's more on the right track than #1. Thanks.

• Characters in string changed after downloading HTML from the internet.

  - by Callum Rogers

  Using the following code, I can download the HTML of a file from the internet: WebClient wc = new WebClient(); // .... string downloadedFile = wc.DownloadString("http://www.myurl.com/"); However, sometimes the file contains "interesting" characters like é to é, ? to ↠and ????? to フシギダãƒ. I think it may be something to do with different unicode types or something, as each character gets changed into 2 new ones, perhaps each character being split in half but I have very little knowledge in this area. What do you think is wrong?

• Inserting only unique values into an array

  - by karl

  I have a set of values that I'm pushing into an array in the order they occur $valsArray = array(); //I process each value from a file (code removed for simplicity) //and then add into the array $valsArray[] = $val; How do I turn this into an associative array instead where the value gets inserted (as $key of associative array) only if it doesn't exist. If it does exist increment its count ($value of associative array) by 1. I'm trying to find a more efficient way of handling those values compared to what I'm doing now.

• Regex find the first word

  - by Pez Cuckow

  I'm trying to use regex to add a span to the first word of content for a page, however the content contains HTML so I am trying to ensure just a word gets chosen. The content changes for every page. Current script is: preg_match('/(<(.*?)>)*/i',$page_content,$matches); $stripped = substr($page_content,strlen($matches[0])); preg_match('/\b[a-z]* \b/i',$stripped,$strippedmatch); echo substr($page_content, 0, strlen($matches[0])).'<span class="h1">'.$strippedmatch[0].'</span>'.substr($stripped, strlen($strippedmatch[0])); However if the $page_content is <p><span class="title">This is </span> my title!</p> Then my regex thinks the first word is "span" and adds the tags around that. Is there any way to fix this? (or a better way to do it).

• C# HttpRequest - Accessing hashtags in url

  - by CloudyOne

  Unfortunately because of the wide use of the word "hashtag" and "httprequest" i couldn't find any search results that gave me an answer on whether something like this is even possible. If i have a url like this: /Orders/Product#12345 The HttpRequest class shows me that the FilePath, RawUrl, and all other members that show the url as /Orders/Product It just gets rid of the hashtag, and i can't find a place to view it. Is there any way for me to be able to see what hashtag is on the end of the URL from the codebehind? I know i could easily make this a QueryString parameter, but i like the way this looks better, so if there's a way to do it, i'd like to find out what it is :) Thanks in advance!

• How do I include 2 tables in one LocalStorage item?

  - by Noor

  I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

• Assignments failing

  - by Andrei Krotkov

  I'm debugging part of a large project in Visual Studio 2005, and stepping through the code line by line. int speed = this->values.speed; int ref = this->values.ref_speed; After stepping past the first line, values.speed has a value of 61, but for some reason, speed is getting assigned the value 58. After the second line, values.ref_speed has a value of 58, but ref gets assigned the value 30. When paused, you can see that the original values are in fact 61 and 58 respectively, but the values getting stored are different. What is causing this behaviour?
