• How to use Map element as text of a JComboBox

  - by llm

  I am populating a JComboBox (using addItem()) with all the elements of a collection. Each element in the collection is a HashMap (so its a ComboBox of Hashmaps..). My question is - Given that I need each item to be a HashMap how do I set the text to apear in the combobox on the GUI? It needs to be the value of a certain key in the map. Normally if I am populating a combobox with my own type, I would just overide the toString() method...but I am not sure how to acheive this since I am using a Java HashMap. Any ideas (if possible, without implementing my own HashMap)? Update: It seems like there isn't anyway to avoid having the object int the JComboBox overide toString() if I want custom functionality..I wish there was a way to (1) specify the objects to be loaded into the JComboBox and (2) specify how these objects are to appear in the GUI.

• Making a relevant search of text in database using regex

  - by madphp

  Can anyone tell me how I could count the possible instances of a keyword in a block of text? I've split a search term up into separate tokens, so just need to run through and do a count for every instance and removing punctuation or other special characters when making the count. Secondly, if someone has inserted search terms surrounded by double quotes, i want to be able to skip explode, but just count instances of that exact phrase. It doesn't have to be case sensitive and I would like to remove punctuation from the phrase when doing the count. Thirdly, in both cases i want to be able to ignore wordpress and html tags. Lastly, if anyone know any good tutorials for relevant searches that answer the questions above, that would cool too. I've got this far. $results = $wpdb->get_results($sql); $tokens = explode('search_terms'); // Re-arrange Relevant Results foreach ($results As $forum_topic){ foreach($tokens As $token){ // count tokens in topic_title if ($token ){ } } }

• WPF TextBlock Overflow Text to the Left

  - by shf301

  As background I have a very long ID that too long to display in the given area of the TextBlock. The interesting portion of the ID is the end, that is the rightmost portion. What I would like to do is have the TextBlock, rather than the text overflowing right and cutting off the rightmost portion, overflow left and cutoff the leftmost portion. That is given the ID 123456 and a TextBlock with enough space to hold four characters, to get the TextBlock to display 3456 rather than 1234 as it does by default. I could manually trim my ID for display, but given a variable spaced font that's not ideal. So is there someway to get WPF do change the overflow direction?

• Firefox 3.5.9 pushes down input:text when all other browsers render it fine

  - by Ad Taylor

  Hi, I have run into a really odd bug with FF3.5.9 (and potentially lower) where it is moving the input:text below the input:submit. The strangest thing with this is that it is working on IE6/7/8, Chrome, Safari and Firefox 3.6. Here is a test page so you can see how it is marked up: http://paste-it.net/public/s6479e6/ I can fix the issue for FF3.5.9 by adding padding-bottom (15px) but this then puts the other browsers out of action. Has anyone else had a similar issue and found a fix? Seems like such a minor issue but I just can't find a fix for it and I am not really into having to absolute position the inputs as that seems too hacky! Thanks for your time, Ad

• Creating C# form fields with events based off of a text file

  - by evolve

  I need to generate windows form fields based off of a text file that I am parsing. I also want to automatically generate validation event handlers which all will be basically the same only the form field and the regular expression which is used to validate the field will change. I'm having a difficult time figuring out the quickest and easiest method to go about doing this. Any pointers in the right direction would really be great, maybe even some keywords that I'm missing. I can only imagine this type of question has been covered before, I just don't know what I'm searching for really.

• Truncate text if it atempts to run into three lines

  - by Jigs

  I have a small about 140px wide aligned next to a picture. In total there is space for four lines of text. The first two lines are reserved for the title and there are two lines of other info. I want the title to be cut if it spans more than two lines else it will push the other info out of line with the bottom of the image. The only solution I could think of was to create a div the height of two lines with an overflow to hidden. However, if the title is only one line it leaves a big gap. The solution can be Jquery, plain javascript, CSS or even PHP (if its possible). TIA

• Improve performance writing 10 million records to text file using windows service

  - by user1039583

  I'm fetching more than 10 millions of records from database and writing to a text file. It takes hours of time to complete this operation. Is there any option to use TPL features here? It would be great if someone could get me started implementing this with the TPL. using (FileStream fStream = new FileStream("d:\\file.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite)) { BufferedStream bStream = new BufferedStream(fStream); TextWriter writer = new StreamWriter(bStream); for (int i = 0; i < 100000000; i++) { writer.WriteLine(i); } bStream.Flush(); writer.Flush(); // empty buffer; fStream.Flush(); }

• MySQL : incrementing text id in DB

  - by BarsMonster

  I need to have text IDs in my application. For example, we have acceptable charset azAZ09, and allowed range of IDs [aaa] - [cZ9]. First generated id would be aaa, then aab, aac, aad e.t.c. How one can return ID & increment lower bound in transaction-fashion? (provided that there are hundreds of concurrent requests and all should have correct result) To lower the load I guess it's possible to define say 20 separate ranges, and return id from random range - this should reduce contention, but it's not clear how to do single operation in the first place. Also, please note that number of IDs in range might exceed 2^32. Another idea is having ranges of 64-bit integers, and converting integer-char id in software code, where it could be done asyncroniously. Any ideas?

• how to add markup to text using JavaScript regex

  - by Richard

  I need to add markup to some text using JavaScript regular expressions. In Python I could do this with: >>> import re >>> re.sub('(banana|apple)', r'<b>{\1}</b>', 'I have 1 banana and 2 apples!') 'I have 1 <b>{banana}</b> and 2 <b>{apple}</b>s!' What is the equivalent in JavaScript? string.replace(regex, newstring) seems to only take a raw string for replacing.

• How to make DropDownList automatically be selected based on the Label.Text

  - by Archana B.R

  I have a DropDownlist in the GridView, which should be visible only when edit is clicked. I have bound the DropDownList from code behind. When I click on Edit, the label value of that cell should automatically get selected in the DropDownList. The code I have tried is: protected void GridView3_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { SqlCommand cmd = new SqlCommand("SELECT Location_Name FROM Location_Table"); DropDownList bind_drop = (e.Row.FindControl("DropList") as DropDownList); bind_drop.DataSource = this.ExecuteQuery(cmd, "SELECT"); bind_drop.DataTextField = "Location_Name"; bind_drop.DataValueField = "Location_Name"; bind_drop.DataBind(); string Loc_type = (e.Row.FindControl("id2") as Label).Text.Trim(); bind_drop.Items.FindByValue(Loc_type).Selected = true; } } When I run the code, it gives an exception error Object reference not set in the last line of the above code. Cannot find out whats wrong. Kindly help

• jQuery - Change background of input field if text getting replaced

  - by ywickham

  I'm currently using jQuery to restrict a text box to number only input as follows: $('input.numbersOnly').keyup(function () { this.value = this.value.replace(/[^0-9\.]/g,''); }); I'd like to let the user know that what they are typing is being rejected by changing the background color of the field. I know that I can change the background of a field using something like this: $('input.numbersOnly').addClass('alertClass'); My question is, how do I combine the two code examples above so that the color of the field changes as the character is getting replaced? My goal is to alert the user that something is wrong with their input as they type it in the field. Thanks!

• Putting links into text in Django

  - by Dane Larsen

  I have a notifications app that generates notifications for users. The notification class has to be really general, because notifications are generated by all sorts of different things. My question is this: How do I insert links into the text of the notifications? What I tried was this: note = Notification(..., notification="""%s %s has accepted the task: <a href="/tasks/%d/">%s</a>.""" % (request.user.first_name, request.user.last_name, task.id, task.name), ...) In retrospect, it's obvious this wouldn't work. How should I go about this? Thanks in advance!

• iPhone SDK 3.0 deprecation of UITableViewCell .text

  - by djt9000

  Came across an SDK3.0 deprecation that I am having a bit of trouble tryinig to figure out. If my declaration of @property (nonatomic, retain) UIImage *rowImage; does not work, nor @property (nonatomic, readonly, retain) UIImage *rowImage; and I @synthesize rowImage; Do I need to write my own setter because @synthesize will not properly handle this? cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell] autorelease]; // Dpericated in SDK 3.0 // //cell.text = controller.title; //cell.image = controller.rowImage; // Using what the documentation says to use Error=== cell.textLabel = controller.title; Error=== cell.imageView = controller.rowImage; Error: Object cannot be set - Either readonly property or no setter found. Hope this makes sense, any help would be appreciated.

• Avoiding jagged text when pasting into vi?

  - by overtherainbow

  Hello Although I have no problem using SecureCRT (5.1.2 build 274) to work from Windows and connect to PC's running Linux, I have a problem when connecting to an embedded Asterisk appliance that provides"vi" through BusyBox 1.4.1 (2008-03-10). The issue I'm having, is that when I paste code into vi, the text appears jagged like this: <?php try { $dbh = new PDO("sqlite:./db.sqlite"); $dbh->exec("CREATE TABLE IF NOT EXISTS customer (id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(255))"); Does someone what the problem is? Is there a way to reconfigure either BusyBox or SecureCRT so that I can paste successfully? Thank you.

• UILabels text disappears when animating

  - by Wilhelm Michaelsen

  I have this code: - (void)my_button_tapped { if (my_button.tag == 0) { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5]; my_label.frame = CGRectMake(450, 455, 200, 20); [UIView commitAnimations]; [my_button setBackgroundImage:[UIImage imageNamed:@"check.png"] forState:UIControlStateNormal]; my_button.tag = 1; } else { [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5]; my_label.frame = CGRectMake(450, 455, 0, 20); [UIView commitAnimations]; [my_button setBackgroundImage:nil forState:UIControlStateNormal]; my_button.tag = 0; } } When I tap my_button first time the label is expanded into 200px width, when I press the button again the label decreases to 0px width but immediately at button press the text disappears. What's wrong?

• How to return an enum ID instead of the enum text in WebAPI

  - by Rodney

  I am using the WebAPI with .NET 4.5. I have a enum called DareStatus which is a list of statuses and their corresponding integer ID's. To minimize bandwidth traffic I want to send the int values of the enums, not the full text as it is currently doing. (I have control over the client so I can map it on the clientside). The strange thing is that in my RTFM-ing everyone seems to have the opposite issue! http://www.ftter.com/desktopmodules/framework/api/dare/getalldares public enum DareStatus : int { All = 0, Accepted = 2, Pending = 1, Declined = 3, Cancelled = 4, Failed = 5, Won = 6 } public IEnumerable<DareInfo> GetDares() { IEnumerable<DareInfo> dareInfos; using (IDataContext ctx = DataContext.Instance()) { var rep = ctx.GetRepository<DareInfo>(); dareInfos = rep.Get(); } return dareInfos; }

• Concatenate text files with Windows command line, dropping leading lines

  - by James

  I need to concatenate some relatively large text files, and would prefer to do this via the command line. Unfortunately I only have Windows, and cannot install new software. type file1.txt file2.txt > out.txt allows me to almost get what I want, but I don't want the 1st line of file2.txt to be included in out.txt. I have noticed that more has the +n option to specify a starting line, but I haven't managed to combine these to get the result I want. I'm aware that this may not be possible in Windows, and I can always edit out.txt by hand to get rid of the line, but is there a simple way of doing it from the command line?

Not sure how this could be done as how would I define what relevance is? Should I maybe read from a RSS feed? Any thoughts on this?
