• Remote application monitoring through Visual GC

  - by Poole

  I am trying to monitor an application available on remote machine using VisualVM & Visual GC. I have enabled the jmxremote on the remote side as follows: -Dcom.sun.management.jmxremote, -Dcom.sun.management.jmxremote.port=8888, -Dcom.sun.management.jmxremote.ssl=false, -Dcom.sun.management.jmxremote.authenticate=false While monitoring through VisualVM, everything runs fine but VisualGC doesn't displays any stats (getting Not Supported for this JVM error). While tried to monitor one local application, VisualGC runs fine... Got success with the remote app once started jstad on the remote jvm. Is this a known issue with VisualGC...? Remote JVM - 1.5 Local JVM - 1.6

• WPF MenuItem Content "Name"...

  - by Kyle

  Hi, I have a LOT of MenuItem(s), and I want to be able to change their "Content" so that it displays in the program. When I load up the program, their "Content Name" is set in a Setter I created.. but the only problem is that I have almost a hundred MenuItem objects, and I need their display names in the program to be different (not the setter's default). I could just create over 100 different "Setter"'s and change one line in them.. but that is very time consuming. Is there a simpler approach? I want to be able to do this in the XAML where I am declaring them. Is there a way to do this? I've been searching and trying different attempts, but nothing so far.. perhaps someone knows? Thanks

• DataGridView: how to focus the whole row instead of a single cell?

  - by Tomas Sedovic

  I'd like to use the DataGridView control as a list with columns. Sort of like ListView in Details mode but I want to keep the DataGridView flexibility. ListView (with Details view and FullRowSelect enabled) highlights the whole line and shows the focus mark around the whole line: DataGridView (with SelectionMode = FullRowSelect) displays focus mark only around a single cell: So, does anyone know of some (ideally) easy way to make the DataGridView row selection look like the ListView one? I'm not looking for a changed behaviour of the control - I only want it to look the same. Ideally, without messing up with the methods that do the actual painting.

• Simply display RSS feed in/on aspx page

  - by Louis van Tonder

  Maybe I am being a n00b here, but for the life of me, I cant find a simple drop in type solution for displaying an rss feed inside an aspx page? I am looking for a simple solution, as when Firefox gets pointed to an rss feed, it just plainly displays it, no thrills, no fuss. I don't want to get into the xml and format it extensively. I just want a basic feed, will style it with font and a:styles. Thats it. Any ideas? EDIT: I am attempting to show a worpress "feed" inside an aspx page...

• Display Ajax Loader while page rendering

  - by Dean

  This is probably a simple question but how can I best use an AJAX loader in ASP.NET to provide a loading dialog whilst the page is being built? I currently have an UpdatePanel with an associated UpdateProgressPanel which contains the loading message and gif in a ProgressTemplate. Currently I have a page that onLoad() goes and gets the business entities and then displays them. While it is doing this I would like to display an AJAX loader. Would it be better to have nothing in the page load and have a hidden button that is triggered onLoadComplete or unLoad() which would then wait for the button click method to complete displaying the UpdateProgressPanel?

• Different background colors for the top and bottom of a UITableView

  - by Aaron Brethorst

  If you look at your Inbox in iPhone OS 3.0's Mail app, you'll see that swiping down displays a grayish background color above the UISearchBar. Now, if you scroll down to the bottom of the table, you'll see that the background color at that end is white. I can think of a couple ways of solving this problem, but they're pretty hacky: Change the table view's background color depending on the current scrollOffset by overriding -scrollViewDidScroll: Give the UITableView a clear background color and then set its superview's backgroundColor to a gradient pattern image. Does anyone know what the "best practice" solution is for this problem? thanks.

• Silverlight, Grids, MVC, HTTP Post

  - by bplus

  I'm trying to create an editable grid using Asp.Net MVC 2 and Silverlight (specifically a grid that displays info from a db and allows users to update that info). So far I've managed to put a silverlight grid on an a view, using this technique However I have no way of getting the updated data from the silver light grid. Is there anyway to get these values posted back to my controller? I'm pretty new to Asp.Net MVC and I'm really only getting started using silverlight. Thanks for any help!

• iPhone SDK: Can a UIButton with custom images display the title?

  - by Harkonian

  If I create a custom UIButton with images for UIControlState normal and UIControlStateSelected, am I still supposed to be able to display the title for the button? Currently I can't. This is how I create my button: UIImage *moveButtonImage = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"button_move_inactive" ofType:@"png"] ]; UIImage *moveButtonSelectedImage = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"button_move_pressed" ofType:@"png"] ]; self.moveButton = [UIButton buttonWithType:UIButtonTypeCustom]; [self.moveButton setImage : moveButtonImage forState : UIControlStateNormal]; [self.moveButton setImage : moveButtonSelectedImage forState : UIControlStateSelected]; [self.moveButton setTitle:@"Test" forState:UIControlStateNormal]; The button title never displays in this case and I'm forced to create my own label to display on the button, which seems like a hacky way of doing things. Maybe I'm doing something wrong here?

  - by James W

  Hello, sorry if this questions is overly basic or has been asked before but I simply cannot figure it out. On my Ruby on Rails site, I have a controller that accesses the fields of a table in my database and displays their "Name" field as a drop-down menu in one of my views. My problem is I need to change the options of that dropdown menu so I need a way to get into the MySQL database and change the values of those fields. Anyone know of a way to do this? It would be much appreciated. Thank you.

• Clean way to output values in ASP.NET MVC Views when value is not null

  - by Swoop

  Is there a better way to write the code below? I have quite a few blocks that are similar, and this is making the code in the Viewpage very messy to work with. The data value with the associated label only needs to be output when certain conditions are met, which is almost always if the value is not null. The options I can think is to use a response.write to atleast minimize the usage of the ASP script tags, or to format the webpage is such a way that the label displays with an appropriate n/a type value. <% if (myData.Balance != null) { %> Balance: <%= String.Format("{0:C}", (myData.Balance))%> <% } %>

• Easy framework for OpenGL Shaders in C/C++

  - by Nils

  I just wanted to try out some shaders on a flat image. Turns out that writing a C program, which just takes a picture as a texture and applies, let's say a gaussian blur, as a fragment shader on it is not that easy: You have to initialize OpenGL which are like 100 lines of code, then understanding the GLBuffers, etc.. Also to communicate with the windowing system one has to use GLUT which is another framework.. Turns out that Nvidia's Fx composer is nice to play with shaders.. But I still would like to have a simple C or C++ program which just applies a given fragment shader to an image and displays the result. Does anybody have an example or is there a framework?

• MySQL searching using many 'like' operators: is there a better way?

  - by DrAgonmoray

  I have a page that gets all rows from a table in a database, then displays the rows in an HTML table. That works great, but now I want to implement a 'search' feature. There is a searchbox, and search-terms are separated by a space. I am going to make it search three fields for the search terms, 'make' 'model' and 'type.' These three fields are VARCHAR(30). Currently if I wanted to search using 3 terms (say 'cool' 'abc' and '123') my query would look something like this. SELECT * FROM table WHERE make LIKE '%cool%' OR make LIKE '%abc%' OR make LIKE '%123%' OR model LIKE '%cool%' OR model LIKE '%abc%' OR model LIKE '%123%' OR type LIKE '%cool%' OR type LIKE '%abc%' OR type LIKE '%123%' That looks really bad, and it will get even worse if there are more search terms or more fields to search. My question to you: is there a better way to search? If so, what?

• Why does java have an interpreter? and not a compiler?

  - by Galaxin

  Iam a newbie to java and was wondering why java have a interpreter and not a compiler? While shifting from c++ to java we come across the differences between these two Compilation process being one of them. 1.A major difference between a compiler and interpreter is that compiler compiles the whole code at once and displays all the errors at a time whereas an interpreter interprets line by line. 2.Also a compiler takes a less time to compile a code when compared to an interpreter. When java was developed for more advanced and easy features and implementations why has it been restricted to a interpreter based on above facts? Is there any special reason why this is so? If yes what is it?

• wordpress image showing up multiple times

  - by JCHASE11

  I am writing a wordpress theme, and have run into a fairly basic problem. By default, when you inset an image into the post, it displays that image at the size you specify, on both the homepage and the single post. I would like to have different sized images, displaying a thumbnail on the homepage, and a full sized image when you click through to the post. I am using wordpress 2.9's new thumbnail feature, which has created great thumbnails for the homepage. But now, I am stuck with a nice thumbnail next to a large photo (on the index/home page). On the single page, it is displaying correctly with just the large picture. Basically, I need to know how to tell wordpress to only display the large post image on the single page, not on the index. Also: I have used the timthumb script, but I think the answer is far more basic then needing plugins or scripts Thanks!

• Business Objects Web Intelligence-style reporting in a Winform app. Is this possible?

  - by George

  I have a WinForm app that displays results in a Gridview control. If a user right mouse clicks on a row, he can then, from a popup menu, select a command to perform on the row much like windows File Explorer. But now I want to be able to give the user the ability to construct a filter so that he can control which rows are displayed in the grid w/o effecting the functionality of the application. I would also like the user to be able to select the columns/fields that he sees in the grid. For the basis of this question, let's assume that the data displayed in grid comes from a single table. business Objects' Web Intelligence and Desktop Intelligence applications give me very flexible and powerful reporting capabilities, but I want to integrate this capability into my WinForm application. Does Business Objects, or maybe Crystal Reports provide this sort of functionality? I can construct my own query builder but I'd rather not reinvent sliced bread.

• Using __str__ representation for printing objects in containers in Python

  - by BobDobbs

  I've noticed that when an instance with an overloaded str method is passed to the print() function as an argument, it prints as intended. However, when passing a container that contains one of those instances to print(), it uses the repr method instead. That is to say, print(x) displays the correct string representation of x, and print(x, y) works correctly, but print([x]) or print((x, y)) prints the repr representation instead. First off, why does this happen? Secondly, is there a way to correct that behavior of print() in this circumstance?

• How do you create a Google Maps-esque drop down dialog?

  - by Daniel Lew

  In the Google Maps application, when you open the menu and click on "Directions", it pops up a dialog that is unique to Google Maps. It keeps the MapView in the background, but displays the search dialog from the top (or bottom, if you're on an old version of Android). I was curious if anyone knew how they achieved this effect. I'm willing to create a custom Dialog, but it seems that Dialogs are designed to pop into the middle of the screen (any other types of dialogs are denied permission as system dialogs). What trick is Google Maps using?

• UIScrollView Does not Scroll

  - by paul simmons

  I have added a long info screen to my iPhone app. The info is a long UIImageView, and it is contained inside a UIScrollView. They are both defined in .xib file. At run-time, initially I set scrollview's position outside window, and when user clicks a button, set its position inside window. This part is OK. But scrollview displays the image but does not scroll. Isn't it enough to place in MainViewContoller.xib, set the contained content, and (at code) set its contentSize equal to the content's size? BTW: I try it at simulator currently.

• Sharepoint navigation customization

  - by ifunky

  Hi, I've just started to use Sharepoint 2007, MOSS is installed but for the extranet I'm working on the publishing isn't switched on. What I need to do is customise the global navigation so that it displays all top level & subsite links, custom links and format it nicely with css for the brand. Sounds easy but it isn't for some reason! I've been reading numerous blogs and things about it but can't seem to find anything other than writing lots of code (which I don't mind) to hook into the API or use a customer provider which sounds extreme for something so simple. I was wondering what are the options for this and any good links to articles appreciated so I can finally get this simeple task done. I see the MOSS navigation has extra options for global navigation but I presume as this isn't enabled I couldn't use the same code/control in the master page? Thanks Dan

• Python - react to custom keyboard interrupt

  - by flixic

  Hello. I am writing python chatbot that displays output through console. Every half second it asks server for updates, and responds to message. In the console I can see chat log. This is sufficient in most cases, however, sometimes I want to interrupt normal workflow and write custom chat answer myself. I would love to be able to press a button (or combination) that would switch to "custom reply mode". What is the best way to do that, or achieve similar result? Thanks a lot!

• Poll database using jQuery/Ajax

  - by Gav

  Hi guys, I am trying to use jQuery (latest version) & ajax to poll a mysql db every x seconds, post.php does a simple search query on the table and limits to 1 row. (eg SELECT id FROM TABLE LIMIT 1) I've got some other jQuery UI (using v1.8) code that displays some modal/dialog boxes on the screen, simply put if post.php returns something from the db I need to initialise the dialog to pop up onto the screen. I've done all the popup stuff I am just having issues joining all these bits together - i've added some pseudo code of how i expect this to work. Thanks in advance var refreshId = setInterval(function(){ $.ajax({ type: "POST", url: "post.php", data: "", success: function(html){ $("#responsecontainer").html(html); } }); }, 2000 );s /* proposed pseudocode */ if (ajax is successful & returns a db row to #responsecontainer) { show jQueryUI modal (done this bit already fortunately) }

• execution of instructions in a child process

  I want to exit from a child process when the execution of os.system(comm) will be executed. My code is: pid = os.fork() if pid == 0: #instruction else: comm = "python file.py" os.system(comm) os.exit(error) Now, my file file.py contains a loop, and I can get out from it only if a condition is satisfied. But, even when the condition is not satisfied, the program exits from the loop and displays the message error. Also it doesn't execute the rest of instructions in file.py. file.py is : while 1: if(condition): break # rest of instructions
