  • How to display icons next to a select1 control with xxforms:tree appearance

    - by user557060
    Hi, I display a list of items via select1 control using xxforms:tree appearance. They are displayed via a code block like: <xforms:itemset nodeset="instance('dataInstance')/*"> <xforms:label ref="fn:concat(./NAME,', ','ID: ',./ID)"/> <xforms:value ref="./ID"/> </xforms:itemset> </xforms:select1> I want to display two icons for each item on the same row as the item: one icon for deleting and one for editing that item, which would all invoke XPL with the item ID as the parameter. The question, how do I render those icons - does itemset support nested trigger elements? If not, how do I go about achieving it (clicking on the item results in an action other than edit or delete, so cannot use that; can show delete/edit on the page shown when user clicks on the item, but want to save that one click if the user just wants to delete the item for example). Thanks.

  • Using Java method to display HTML code

    - by javArc
    Hey folks, ok so this is my problem, I need to display HTML code in a jsp, which wouldn't be a problem, except a requirement for this project is that we place all the code in a public class file and have seperate methods for each chunk(header, sidebar footer, etc). Now here's where i'm confused: "Your method should take the PrintWriter as a parameter to print out each line of HTML, and should have a return type of void" What does that mean? How do I pass the PrintWriter into a method? Does this make sense to anyone?

  • Reading in a file - Warning Message in R

    - by Sheila
    I have a file that has 22268 rows BY 2521 columns. When I try to read in the file using this line of code: file <- read.table(textfile, skip=2, header=TRUE, sep="\t", fill=TRUE, blank.lines.skip=FALSE) I get the following error: Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : number of items read is not a multiple of the number of columns I also used this command to see what rows had an incorrect number of columns: x <-count.fields("train.gct", sep="\t", skip=2) which(x != 2521) and got back a list of about 20 rows that were incorrect. Is there a way to fill these rows with NA values? I thought that is what the "fill" parameter does in the read.table function, but it doesn't appear so. Any help would be greatly appreciated. Thank you.

    - by Andrey Khataev
    Hello, I have my app, using functionality that is based on unity application block. Sometimes I need to throw ResolutionFailedException manually. In v1.2 constructor of ResolutionFailedException had three parameters - typerequested, namerequested and exception. In v2.0 fourth parameter was added - buildercontext.

Roughly speaking, I'm only overriding Resolve method in particular way and I'm not interfere in standard mechanism of policies, strategies and so on. Could anyone help?

  • Open URL with Safari no matter what system browser is set to

    - by Mark
    In my objective-c program, I need to open a URL in Safari no matter what the system's default browser is. That means that this won't work, because it could launch Firefox or whatever other browser: NSWorkspace * ws = [NSWorkspace sharedWorkspace]; [ws openURL: url]; I think I'm close with this: [ws launchAppWithBundleIdentifier: @"com.apple.Safari" options: NSWorkspaceLaunchWithoutActivation additionalEventParamDescriptor: NULL launchIdentifier: nil]; only need to figure out how to pass in the URL as parameter... Is there an easier way? Thanks!

  • Wrap Sub as Function for use in Lambda

    - by Luhmann
    I have a problem with VB and Moq. I need to call a verify on a Sub. Like so: logger.Verify(Function(x) x.Log, Times.AtLeastOnce) And my logger looks like this: Public Interface ILogger Sub Log() End Interface But with VB this is not possible, because the Log method is a Sub, and thereby does not produce a value. I don't want to change the method to be a function. Whats the cleanest way of working around this limitation and is there any way to wrap the Sub as a Function like the below? logger.Verify(Function(x) ToFunc(AddressOf x.Log)) I have tried this, but i get: Lambda Parameter not in scope

  • Serialze an Object to a String

    - by Vaccano
    I have the following method to save an Object to a file: // Save an object out to the disk public static void SerializeObject<T>(this T toSerialize, String filename) { XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType()); TextWriter textWriter = new StreamWriter(filename); xmlSerializer.Serialize(textWriter, toSerialize); textWriter.Close(); } I confess I did not write it (I only converted it to a extension method that took a type parameter). Now I need it to give the xml back to me as a string (rather than save it to a file). I am looking into it, but I have not figured it out yet. I thought this might be really easy for someone familiar with these objects. If not I will figure it out eventually.

  • How to pass a const unsigned char * from c++ to c#

    - by tzup
    So I have a function in unmanaged c++ that gets called when some text happens to have "arrived": #using <MyParser.dll> ... void dump_body(const unsigned char *Body, int BodyLen) { // Need to pass the body to DumpBody, but as what type? ... lMyParser::Parser::DumpBody(???); } DumpBody is a function defined in a C# DLL that should take one parameter of type? Body holds an array of characters (text) of length BodyLen. There's obviously some marshalling to be done here but I have no idea how. Please help.

  • How to do REST with PUT and DELETE

    - by Svish
    It says about the type option of the jQuery.ajax() method that The type of request to make ("POST" or "GET"), default is "GET". Note: Other HTTP request methods, such as PUT and DELETE, can also be used here, but they are not supported by all browsers. So... Does that mean that PUT and DELETE won't work if the browser does not support it, or just that PUT and DELETE can not be done natively by the user in the browser? If I can't or shouldn't use those, what do people usually do instead? Send the method as a a GET or POST parameter instead? Or?

  • Operator as and generic classes

    - by abatishchev
    I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

  • how to listen to Enter button when using JOptionPane.showOptionDialog

    - by MemoryLeak
    I use: char[] password = null; JPasswordField jpf = new JPasswordField(30); java.lang.Object [] messageInput = { prompt, jpf }; java.lang.Object [] options = { jpf , "OK", "Cancel"}; int result = JOptionPane.showOptionDialog(null, messageInput, title, JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, ""); JOptionPane.showMessageDialog(null, result); if (result == 1) { password = jpf.getPassword(); } else if(result == JOptionPane.CANCEL_OPTION) { } return password; to get password, but this can not listen to the Enter button. I know if I set the options parameter to null, can make the dialog listen to "enter" button, but if I do that, the dialog don't focus to the textbox when show up. Can someone help me on this ? Thanks in advance !

  • How to use php variables (arrays) in mysql select statements?

    - by davidconn
    Hi everybody, How do you use a php variable (array) inside a mysql select statement? I am designing an auction site and currently working on a page that lets people view a list of all the current bids for an item. I want to display 3 columns: amountbid - the amount each bidder has bid for the item (held in tblbid) bidderid - the id of each bidder who has bid (found in tbluser) total_positivity_feedback - how many users have left positive feedback for the bidder (calculated from tblfeedback) To find the 'amount' and the 'bidderid' columns i pass the essayid URL parameter from the previous page. This works fine. Despite this, i can't display the total_positivity_feedback column for the various users who have made each bid. My mysql query looks like this: select tblbid.bidderid, tblbid.amount, (select count(tblfeedback.feedbackid) from tblfeedback WHERE tblfeedback.writerid = "ARRAY VARIABLE GOES HERE") AS total_positivity_feedback FROM tblbid WHERE tblbid.essayid = $essayid_bids I assume that the only way to accomplish this is to make the variable contain the bidderid's of those people who bid for that particular essay? I can't seem to work out how to do this tho?!? Many thanks for your help

  • Stored procedure for selecting multiple records

    - by padmavathi
    I need to select records say 2000 from a table with a matching timestamp from c# .net code. Eg: SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME='Item1' and TimeStamp='2010-04-26 17:15:05.667' The above query has to execute for 2000 items more for the same timestamp. for this we can use SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME in ('Item1','Item2','Item3','Item4',......) AND TimeStamp='2010-04-26 17:15:05.667' from SQL Server Management Studio. I have tried appending all Item names to one string variable and giving it as a parameter to the stored procedure,but it resulted into a wrong concatenation. How can I do this as a stored procedure executing from the .net code? Can anyone suggest me/correct me in doing this? Thanks & Regards Padma

  • How do I make a multiple file upload?

    - by Bluemagica
    I am trying to make a multiple image uploader. The file upload fields are being added in the form dynamically using jquery. I tried making an array of the fields since I don't want to have a hidden field. so my generated upload fields look like <input type="file" id="img0" name="img[]"/> <input type="file" id="img1" name="img[]"/> <input type="file" id="img2" name="img[]"/> ..... .. And on the php side I did something like if(isset($_FILES['img'])) { foreach($_FILES['img'] as $k=>$v) { if($v!="") { uploadImage($k,0,0,0,"content/gallery/"); } } } Now I know I am way too wrong, since in that code I am looping through the 'img' file's properties instead of all images....but I have no idea how to fix this. PS: uploadImage is a function I wrote which expects the file input field's name as the first parameter.

  • Segmentation fault C++ in recursive function

    Why do I get a segmentation fault in my recursive function.

  • Beginner C++ Question

    - by Donal Rafferty
    I have followed the code example here toupper c++ example And implemented it in my own code as follows void CharString::MakeUpper() { char* str[strlen(m_pString)]; int i=0; str[strlen(m_pString)]=m_pString; char* c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } } But this gives me the following compiler error CharString.cpp: In member function 'void CharString::MakeUpper()': CharString.cpp:276: error: invalid conversion from 'char*' to 'int' CharString.cpp:276: error: initializing argument 1of 'int toupper(int)' CharString.cpp: In member function 'void CharString::MakeLower()': This is line 276 putchar (toupper(c)); I understand that toupper is looking for int as a parameter and returns an int also, is that the problem? If so how does the example work?

  • Why is this consider bad practice? or is it? (ASP.Net)

    - by user318573
    Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

  • What's the most auditable way to organize database maintenance scripting/scheduling?

    - by RenderIn
    I'm using PHP, Oracle and crontab. Crontab is invoking a php script, which is going to synchronize some data between a local and remote database. First I thought about putting this all in one large, anonymous inline PL/SQL block and executing it in PHP. The problem is that without creating a table to audit the procedure it's really opaque to my PHP code until it returns. And then when it does return, the best I can do is receive a string in an out parameter which I've concatenated together as an audit log. Then I considered breaking it up into several SQL statements and have PHP do some intermediate auditing/logging and manipulation of the data between each of them. I'm not really satisfied with either of these. How do you organize maintenance code that is called in a cronjob?

  • How to update (append to) an href in jquery?

    - by John Isaacks
    I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

  • Can I use a single instance of a delegate to start multiple Asynchronous Requests?

    - by RobV
    Just wondered if someone could clarify the use of BeginInvoke on an instance of some delegate when you want to make multiple asynchronous calls since the MSDN documentation doesn't really cover/mention this at all. What I want to do is something like the following: MyDelegate d = new MyDelegate(this.TargetMethod); List<IAsyncResult> results = new List<IAsyncResult>(); //Start multiple asynchronous calls for (int i = 0; i < 4; i++) { results.Add(d.BeginInvoke(someParams, null, null)); } //Wait for all my calls to finish WaitHandle.WaitAll(results.Select(r => r.AsyncWaitHandle).ToArray()); //Process the Results The question is can I do this with one instance of the delegate or do I need an instance of the delegate for each individual call? Given that EndInvoke() takes an IAsyncResult as a parameter I would assume that the former is correct but I can't see anything in the documentation to indicate either way.
