  • Using SqlCacheDependency to get real time updates? - ASP.NET

    - by user102533
    I would like to display real time updates on a web page (based on a status field in a database table that is altered by an external process). Based on my research, there are several ways of doing this. Long Polling (Comet) - This seems to be complex to implement Regular Polling - I can have an AJAX method trigger a database hit every 5seconds to get the current status. But I fear this will have performance issues. Then I read about using SqlCacheDependency - basically the cache gets invalidated based on a field in the table. I am assuming I can use the event trigerred when the cache is invalidated to show the new update to the user? What's an easy solution that will not have performance issues? anyone?

  • RichTextBox doesn't update caret position correctly

    - by shadeMe
    I have a handler consuming the keyDown event of a WinForms RTB, that has the following code: GetTextAtLoc(RTB->SelectionStart); // selects some text at the caret's position RTB->SelectedText = "SomeOfMyOwn"; GetTextAtLoc(RTB->SelectionStart); // selects the replacement string RTB->SelectionStart += RTB->SelectionLength - 1; While this code seems to do its job (SelectionStart/Length properties are updated correctly), the caret doesn't move to the end of the new string - It says right where it was at the time of GetTextAtLoc's first call. Redrawing the textbox does seem to have any effect either.

  • A very weird problem with texbox control in .net

    - by Kazoom
    Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

  • Setting a Silverlight textbox control's width relatively

    - by John K.
    Hello, I tried searching on stackoverflow for an answer to my question but couldn't seem to find anything relevant. Since I'm relatively new to Silverlight, I'm not even sure if this is possible, but I am trying to figure out if it is possible to set a Silverlight textbox control's width value proportionally to it's immediate parent container? It would be nice to avoid hard coding a width value. Say you want to place a textbox control inside a horizontally aligned StackPanel control and have it's width always dynamically adjusted to be 80% of the total width of the StackPanel. Is this possible to do declaratively in your xaml markup, or will I need to resort to some codebehind attached to some event handler to accomplish this? fyi, I am currently using Visual Web Developer Express 2008 to write my silverlight code. thanks in advance, John

  • how to install mysqlDb for MySQL and Python ON WINDOWS

    - by Spikie
    I AM A NET DEVELOPER TRY TO INSTALL MYSQLDB FOR PYTHON I KEEP HAVING THIS ERROR MESSAGE raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb I AM FOLLOWING THIS INSTRUCTION FROM THIS SITE <"http://sourceforge.net/project/shownotes.php?release_id=303257" I DO NOT UNDERSTAND THESE LINES Windows ....... C:... python setup.py install C:... python setup.py bdist_wininst The latter example should build a Windows installer package, if you have the correct tools. In any event, you must have a C compiler. Additionally, you have to set an environment variable (mysqlroot) which is the path to your MySQL installation. In theory, it would be possible to get this information out of the registry, but like I said, I don't do Windows, but I'll accept a patch that does this. I HAVE BEEN SEARCHING FOR ANSWER ALL DAY PLEASE DO ANYBODY REALLY KNOW HOW TO DO THIS OR AT LEAST POINT ME IN THE RIGHT DIRECTION???? THANKS and what is the c compiler for???????

  • change fillColor of selected CAShapeLayer

    - by Frank
    I'm trying to change the fillColor of a CAShapeLayer when the layer it's contained in is touched. I'm able to change the background color of the tapped layer like this: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { CALayer *layer = [(CALayer *)self.view.layer.presentationLayer hitTest:point]; layer = layer.modelLayer; layer.backgroundColor = [UIColor blueColor].CGColor; } This turns the background of "layer" blue as expected. My problem is how do I change the color of the CAShapelayer inside "layer"? Thanks!

  • Insert an ajaxified Webpart into an existing MOSS site

    - by mamoo
    Hi everybody, I need to code a webpart which purpose is to asynchronously fetch some documents and display them into an existing page. Unfortunately I have to face a lot of rescritcions and my struggle to find a solution seems useleess so far. 1) I cannot use Microsoft asp.net ajax 2) I must use Jsonp because the called service (page, whatever...) is outside the site's domain. That's not a big problem. 3) I have no possibility to alter the existing page code, so I cannot reference an external library such as JQuery. 4) For the same reason I have no possibility to call my methods on the window.onLoad event, so here the question is: how can I be sure that everything is correctly loaded before triggering my ajax call? 5) Since several instances of the same webpart can be placed into the same page, can there be some possible conflicts among the various js functions?

  • SL4 - Binding DataGridTextColumn to a property

    - by Brent
    I have a DataGrid. In the DataGrid's AutoGeneratingColumn event I have some code that looks like this: if (e.Property.Name.Contains("MetaData")) { var descCol = new DataGridTextColumn(e.Property); var bnd = new Binding("Description"); bnd.Mode = BindingMode.TwoWay; descCol.Binding = bnd; e.Column = descCol; e.Column.Header = "Description"; return; } The column binds to a type MetaData which has a string property named Description that I would like displayed in my DataGrid. So far I've been unable to get the value of the Description property to display in my DataGrid. I think the path I am passing into the Binding constructor might be incorrect. I've tried "MetaData.Description" as well and it doesn't work either. Can anyone help me properly set up the binding on my DataGridTextColumn?

  • How can I pause a BackgroundWorker? Or something similar...

    - by juan
    I was using a BackgroundWorker to download some web sites by calling WebClient.DownloadString inside a loop. I wanted the option for the user to cancel in the middle of downloading stuff, so I called CancelAsync whenever I found that CancellationPending was on in the middle of the loop. But now I noticed that the function DownloadString kinda freezes sometimes, so I decided to use DownloadStringAsync instead (all this inside the other thread created with BackgroundWorker). An since and don't want to rewrite my whole code by having to exit the loop and the function after calling DownloadStringAsync, I made a while loop right after calling it that does nothing but checks for a variable bool Stop that I turn true either when the DownloadStringCompleted event handler is called or when the user request to cancel the operation. Now, the weird thing is that it works fine on the debug version, but on the release one, the program freezes in the while loop like if it were the main thread.

  • ASP.NET - Web Application, UserControls and NullReferenceExceptions

    - by Echilon
    I have a web application, which works fine if I include my user controls with <%@ Register TagPrefix="mine" TagName="MyUC1" Src="~/UserControls/MyUc1.ascx" %> <%@ Register TagPrefix="mine" TagName="MyUC2" Src="~/UserControls/MyUc2.ascx" %> But I need to use the namespace due to needing to integrate with Umbraco. When I replace the register declaration with: <%@ Register TagPrefix="mine" Namespace="MyAssembly.UserControls" Assembly="MyAssembly"%> I get a null reference exception in the UserControl's Page_Load event (which references an ASP.NET control which is used by the UserControl itself. I find this pretty bizarre, but I've found very little information on how to fix it.

  • Miss a single tap randomly

    - by pion
    I have the following code snippets - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; NSUInteger numberTaps = [touch tapCount]; // Tapping if (numberTaps > 0) { // do something } ... The above code basically detects a single tap on a small image (width = 18 and height = 36). It works 90% of the time detecting a single tap. But it sometime misses it (randomly). I have to tap several times before it picks up the single tap. What did I do wrong or miss so I could consistently detect the single tap 100%? Thanks in advance for your help.

  • Change NSButton Background Image more than once per second

    - by beta
    I am currently working with the iPhone SDK. I have a NSTimer that changes the background image of a NSButton. Once this is complete, it will trigger the same action again (reset the NSTimer) for a predetermined number of times. My problem is that if my NSTimer is set to execute more than once per second. (0.75, say) The background image wont change. I am using NSLog to check that the event fires. But the button image will just remain in its original state. Is there any way to change the background image more often than once per second? Thanks.

  • C# UserControl factory

    - by user1112111
    Let's say you have two classes that extend UserControl. Each of the controls provides a custom event (this could be done by using an interface). You want to display one of the controls in the odd days and the other in the even days. You also want to be able to drag&drop (Visual Studio) the UserControl on your form without knowing what the Control type will finally be. How do you do that ? Is the factory pattern useful here ?

  • Come meet our Interns in Dublin

    - by klaudia.drulis
    Oracle Worldwide Product Translation Group (WPTG) provides solutions for all Oracle product and Content translation requirements. WPTG is a global organisation with its headquarters in Ireland and employees in Oracle offices worldwide. WPTG offer expertise in fields such as process engineering, tools development, linguistic quality, terminology, global product release, financial and vendor management. WPTG provides translation solution for over 40 languages including Asia Pacific, European, American and Middle Eastern languages. WPTG first introduced an intern program over 10 years ago and it has become a key component of our teams structure. The majority of Interns are sourced from a Computer Science related course, these Interns joining the engineering team. Others are sourced from Business courses and work within the Business / Project management area. The intern program allows us to maintain ties with current course curriculum and brings fresh energy and perspective into our Organisation. Four of the full time staff working in Dublin today joined us originally as Interns and subsequently were offered permanent positions. Come Meet some of our 2010 Interns, Come and see what Darragh, Anthony, Caoimhe, James and Artemij thought about working within the WPTG at Oracle: Darragh “Oracle has been a fun, challenging work placement for me. From day one I was treated as a full member of staff, this was both comforting and a little bit scary. The responsibilities stack up but I found I was able to keep on top of everything and even make improvements to how we handle a few things thanks to a great team and a very supportive manager. There’s a very positive atmosphere in work that’s really conducive to getting a lot of work done. Ideas seem to be the central hub in my line of business so all of my ideas and innovations were greeted with enthusiasm. Oracle has given me a fantastic opportunity and I urge you to grab it with both hands, you’ll find that you’re with a set of like minded people from all works of life that make work both interesting and fun. Even when the pressure is on you know that you can always get help and advice from someone nearby. My last word of advice is don’t be afraid to stick your neck out, everyone here is willing to learn, try something new and innovate, your voice will be heard and who knows, you could end up having a large impact on Oracle and your career.” Anthony “I had a great experience working with Oracle, from day one I was treated like a full member of staff with responsibilities of my own. I found that the more I put into the work the more I got out from the experience. Volunteering and being willing to face challenges have made this a more exciting placement. I am given a lot of leeway to do my own projects and so I’ve found that I am really enjoying my time here.” Caoimhe “I am currently spending my year of placement within the Release Management Team in the WPTG. My main role is to handle the finance process of all translation projects under 100k which includes creating workspecs and PO's, sending out kits, dealing with vendor queries and handling the invoicing and payment part. I am really enjoying my time here at Oracle, everyone is very open and friendly and willing to help you out with any questions you may have. I would definitely be interested in returning to Oracle after I graduate!” James “I am currently on a 12 month placement with Oracle, working as part of the Worldwide Product Translation Group in the Business Management. The Business Management team provides a global view on WPTG’s vendor and business strategy and is an interface into WPTG for new business. The business management team work together to support the external translation partner network. My role is to support the Business Management team and also to work on various projects when the need arises. This involves working with translation vendors and working with other Oracle employees worldwide. I am really enjoying my time working for Oracle, at times it can be challenging bit also very rewarding. I would recommend any student wanting to undertake a placement year to apply to Oracle, I made some great friends and I will never forget my time in Dublin.” Artemij “From working within Oracle, I have truly understood what "career path" is, and what opportunities a large corporation like Oracle can offer. Without any illusions, the work itself is exciting, sometimes challenging, tests your ability to handle pressure, to make decisions and take responsibility, to learn quickly and cooperate efficiently in order to solve a problem. I have learned a lot about myself. What I am good at, where and what I can do better. My placement at Oracle has allowed me to get a clearer picture of what I want, and which door I am going to open after college.

  • [C#] Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

    - by Luke Mcneice
    Hi all, I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?
