  • dynamic LinkButton OnClick event not working on ASP.Net

    - by user1004472
    I want to create dynamic LinkButton for image, <img> tag is not working dynamically so I am using LinkButton with image. I don't want to provide ID to LinkButton because I want to generate more LinkButton dynamically. I am using following code in Default.aspx <%@ Page Language="C#"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { Response.Write(@"<asp:LinkButton runat=""server"" OnClick=""btn_click""><img src=""close-icon (1).png"" /></asp:LinkButton>"); } public void btn_click(object sender, EventArgs e) { Response.Write("HELLO"); } </script> </head> <body> <form id="form1" runat="server"> <div> </div> </form> </body> </html> I also tried to write tag code in Default.aspx.cs file but not work. It's showing me following error. Error 1 'ASP.default_aspx' does not contain a definition for 'img_Click' and no extension method 'img_Click' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?) Please help me to solve this problem.

  • How to move from custom to transluscent NavigationBar and back? Display problems!

    - by jd291
    So, i got this Navigation-based App (with a custom NavigationBar - Category) and I have 2 problems here... @implementation UINavigationBar (Custom) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"bg_toolbar.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end Because of the Navigation-based App, most of the views have a height of 436px (= ScreenSize - NavigationBar height, as you probably know ;). I got one view similar to the photo app overview showing all the thumbnails, from there I push a viewcontroller containing the scroll view (like in photos app) on the stack, like so - (void)buttonPressed:(id)sender { UIButton *btn = (UIButton *)sender; PhotoSetScrollViewController *psc = [[PhotoSetScrollViewController alloc] initWithPhotoArray:photos andID:btn.tag]; [self.navigationController pushViewController:psc animated:YES]; } Problem 1: The view holding the fullscreen scrollview has a height of 480px which seems to be a problem because when poping the viewcontroller by hitting the back button, the view containing the thumbnails (height 436px) moves upward below the navigation bar. And also the Toolbar keeps showing. What could be the problem? Problem 2: How could I switch between my custom navigation bar and the standard black translucent style?

  • 32 vs 64-bit software for same machine?

    - by GorillaSandwich
    What is the difference between 32 and 64-bit software? My understanding is that 64-bit can use more RAM, if it's available, because it has a larger address space for it. Is this correct? And, specifically: If I have a 64-bit operating system with lots of RAM, and I install, say, the 32-bit version of MySQL instead of the 64-bit version, will it be unable to use all the available RAM and therefore run slower than the 64-bit version might on the same machine (assuming RAM becomes the bottleneck before processing speed or disk access speed or whatever)? If I have a 32-bit operating system and I install a 64-bit piece of software on it, will it (probably) fail to run?

  • How to batch convert video files on OSX for AppleTV2 / iPhone4?

    - by Luke404
    I'd like to have a solution to batch convert video files to a format suitable for the AppleTV2, iPad2, iPhone4, while at the same time preserving as much quality as possible; I want a single output file that will play on both devices and also good for consumption by other Mac software (eg. Aperture, iMovie, iTunes). Batch processing is a requirement since I'm gonna convert many many files from different sources (mainly lots of videos captured by compact digital cameras, cell phones, and so on). I'm looking into ffmpeg and MEncoder (both installed via MacPorts), but I can't seem to find a suitable preset for libx264 even if everyone out there is talking about them. A different approach involving different software would be ok too as long as I can script it somehow and run it on a whole directory full of files to be converted.

  • Help with MySQL query... Need help ordering a group of rows

    - by user156814
    I can tell it best by explaining the query I have, and what I need. I need to be able to get a group of items from the database, grouped by category, manufacturer, and year made. The groupings need to be sorted based on total amount of items within the group. This part is done with the query below. Secondly, I need to be able to show an image of the most expensive item out of the group, which is why I use MAX(items.current_price). I thought MAX() gets the ENTIRE row corresponding to the largest column value. I was wrong, as MAX only gets the numeric value of the largest price. So the query doesnt work well for that. SELECT items.id, items.year, items.manufacturer, COUNT(items.id) AS total, MAX(items.current_price) AS price, items.gallery_url, FROM ebay AS items WHERE items.primary_category_id = 213 AND items.year <> '' AND items.manufacturer <> '' AND items.bad_item <> 1 GROUP BY items.primary_category_id, items.manufacturer, items.year ORDER BY total DESC, price ASC LIMIT 10 if that doesnt explain it well, the results should be something like this id 10548 year 1989 manufacturer bowman total 451 price 8500.00 (The price of the most expensive item in the table/ not the price of item 10548) gallery_url http://ebay.xxxxx (The image of item 10548) A little help please. Thanks

  • Objective-C / Cocoa: Uploading Images, Working Memory, And Storage.

    - by Finley Still
    Hello. I'm in the process of porting an application originally in java to cocoa, but I'm rewriting it to make it much better, since I prefer cocoa a lot anyway. One of the problems I had in the application, was that when you uploaded images to it, I had the images created, (as say an NSImage object) and then I just had them sitting in memory, the more I uploaded the more memory they took up, and I ended up running out of memory. My question is this: if I am going to have users upload images to this application in cocoa, how should I go about storing them? I don't just want to copy the file paths, because I want what is saved to contain the images, etc. Is there any way to upload an image and copy it into a different place only for my application? Then load that image with the new path name as needed? Only I would like it all to be consolidated. I'm going to implement saving by archiving one "master" object into an NSData*- so I'd like the images to be saved with that. Is there a temporary location maybe where I could write the images to disk for my application, and then when I saved, they would all be archived into a single file? Also, how do I do this? Thanks.

  • Semantically correct XHTML markup

    - by Dori
    Hello all. Just trying to get the hang of using the semantically correct XHTML markup. Just writing the code for a small navigation item. Where each button has effectivly a title and a descrption. I thought a definition list would therefore be great so i wrote the following <dl> <dt>Import images</dt> <dd>Read in new image names to database</dd> <dt>Exhibition Management</dt> <dd>Create / Delete an exhibition </dd> <dt>Image Management</dt> <dd>Edit name, medium and exhibition data </dd> </dl> But...I want the above to be 3 buttons, each button containing the dt and dd text. How can i do this with the correct code? Normally i would make each button a div and use that for the visual button behaviour (onHover and current page selection stuff). Any advice please Thanks

  • Jquery selectors question

    - by Ben
    Hi all, I am not an expert at jquery but trying to get a menu to work. Basically, I have a menu made of up to 3 levels of nested lists. The first level has a little arrow has a background image that opens or close when opening the first level list. Any other nested lists don't need to have the background image. My script opens the menu when you click on it and is also supposed to switch the first level list from a class "inactive" to a class "active". Here is the script: $(document).ready(function(){ $("#left-navigation-holder ul.level1 li.inactive").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); $("#left-navigation-holder li a").click(function(){ menu = $(this).parent('li').children('ul'); menu.toggle(); }); }); The problem is that the toggle function also happens when clicking on second and third level lists causing the arrows to toggle even if the first level list isn't clicked on. I thought using $("#left-navigation-holder ul.level1 li.inactive").toggle would limit the function to the first level list with a class "inactive". Any help would be really appreciated. Ben

  • Supporting Piping (A Useful Hello World)

    - by blastthisinferno
    I am trying to write a collection of simple C++ programs that follow the basic Unix philosophy by: Make each program do one thing well. Expect the output of every program to become the input to another, as yet unknown, program. I'm having an issue trying to get the output of one to be the input of the other, and getting the output of one be the input of a separate instance of itself. Very briefly, I have a program add which takes arguments and spits out the summation. I want to be able to pipe the output to another add instance. ./add 1 2 | ./add 3 4 That should yield 6 but currently yields 10. I've encountered two problems: The cin waits for user input from the console. I don't want this, and haven't been able to find a simple example showing a the use of standard input stream without querying the user in the console. If someone knows of an example please let me know. I can't figure out how to use standard input while supporting piping. Currently, it appears it does not work. If I issue the command ./add 1 2 | ./add 3 4 it results in 7. The relevant code is below: add.cpp snippet // ... COMMAND LINE PROCESSING ... std::vector<double> numbers = multi.getValue(); // using TCLAP for command line parsing if (numbers.size() > 0) { double sum = numbers[0]; double arg; for (int i=1; i < numbers.size(); i++) { arg = numbers[i]; sum += arg; } std::cout << sum << std::endl; } else { double input; // right now this is test code while I try and get standard input streaming working as expected while (std::cin) { std::cin >> input; std::cout << input << std::endl; } } // ... MORE IRRELEVANT CODE ... So, I guess my question(s) is does anyone see what is incorrect with this code in order to support piping standard input? Are there some well known (or hidden) resources that explain clearly how to implement an example application supporting the basic Unix philosophy? @Chris Lutz I've changed the code to what's below. The problem where cin still waits for user input on the console, and doesn't just take from the standard input passed from the pipe. Am I missing something trivial for handling this? I haven't tried Greg Hewgill's answer yet, but don't see how that would help since the issue is still with cin. // ... COMMAND LINE PROCESSING ... std::vector<double> numbers = multi.getValue(); // using TCLAP for command line parsing double sum = numbers[0]; double arg; for (int i=1; i < numbers.size(); i++) { arg = numbers[i]; sum += arg; } // right now this is test code while I try and get standard input streaming working as expected while (std::cin) { std::cin >> arg; std::cout << arg << std::endl; } std::cout << sum << std::endl; // ... MORE IRRELEVANT CODE ...

  • Telerik chart not loading correctly in new window (ajax issue?)

    - by Phillip Schmidt
    I have a page which contains user controls with Telerik Charts (grids also, but they work fine). From this page, the user can click on a button to be redirected to a "Printer-Friendly Version" type page, which opens a new window via javascript and goes through a slightly different view (for formatting and stuff), but the telerik code is all the same. The problem is, my Chart displays just fine in the original window, but the new window displays basically an empty chart with no data. This bug is only present in IE, and only applies to Charts. Grids work fine, for whatever reason. I'm thinking this is due to differences in script caching between browsers -- correct me if I'm wrong, I'm semi-new to client-directed web development. Anyway I read somewhere that Telerik has issues with loading data and/or js files when loaded via ajax, so maybe that's the problem? If so, how could I get around this? And if not, any ideas on what could be causing this issue? It's causing me a great deal of frustration, since a print preview page seems like it should be the easiest of jobs. Edit: The charts are being rendered as html (if somebody can explain how to render them as images, that would be awesome). And dev tools shows basically the same thing between chrome and IE. Whenever my web service goes back up ill WinMerge them and look for any peculiarities/differences between them. In the mean time, though, the "render as an image" concept sounds promising. That way I could just save the image from the first page, and insert it right into the print preview page, right?. And since it's a print-preview page, it's not going to need to be interactive or anything, so that'd work out nicely. Another (important) Edit: These are probably the culprit... And here is a little more detail on that: And here is a side-by-side of it working(in chrome) and not working (in IE):

  • iPhone: How to Determine Average Light/Dark of an Area of an UIImage

    - by TechZen
    I need to place labels with a transparent background over a variable-content UIImage. Readability will vary significantly depending on the relationship between the color of the label's text and the color/luminosity of the area of the image displayed under the label. Since the image will be constantly changing, the color of the label's text needs to change in sync. I have found several techniques for determining the color, perceived luminosity etc of a single pixel. However, I need to rather quickly (while a view loads) determine the rough perceived color/luminosity of an area of the UIImage under the frame of the UILabel. I presume I will also need to measure the alpha because the same color/luminosity looks different at different alpha values. Is there a way to calculate such a value for an area? Will I be reduced to simply summing pixels? If it comes to that, is there an algorithm to accomplish this? I've thought of two possible approaches: Perform some "folding" operations i.e. combining pixels from one half of the area to the other half. Then repeat until I get a single value. Would this be practical? How would you logically combine pixels to average their perceived color/luminosity? Sample a statistically significant number of pixels in the area and then combine them (somehow) to get a rough measure. I think this problem comes up a lot these days with people being so found of customizing backgrounds. Seems like something that would be worth my time to bang out a category or class to handle this and then share it around.

  • Get ViewData IList back on postback in ASP.NET MVC

    - by Thomas
    I have the following in my view: <%using (Html.BeginForm()) {%> <% foreach (var item in Model.Cart) { %> <div> <%= Html.TextBox("Cart.Quantity", item.Quantity, new { maxlength = "2" })%> <%= Html.Hidden("Cart.ItemID", item.ItemID)%> </div> <% } %> <input name="update" type="image" src="image.gif" /> <% } % I then have this code in my controller: public ActionResult Index() { CartViewData cartViewData = new CartViewData(); IList<Item> items = ItemManager.GetItems(); cartViewData.Cart = items; return View("Index", cartViewData); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Index(CartViewData cartViewData) { // cartviewData is null } Is there a way to grab the List on the postback to see if the values in the textboxes have changed? Thanks Below is a simplified example since it was requested: <% for (int i = 0; i < Model.Cart.Count; i++ ) { %> <a href="javascript:void(0);" onclick="removeItem(<%= Model.Cart[i].ShoppingCartItemID %>);">Remove</a> <% } %> Hope this helps.

  • IE7: container of hidden Div displays incorrectly

    - by dmr
    There is a search box div that contains a boxhead div and a boxbody div. Inside the boxbody div, there is a searchToggle div. When the user clicks a certain link on the page, the display style property of the searchToggle div is toggled between block and none. The 2 background-images for the body of the search box are set via the css of the searchBox div and the boxbody div. In IE7, when the searchToggle div is hidden, the background-image from the searchBox div extends on the left more than it should. It shows up correctly when the display of the searchToggle div is block. Everything show up correctly, in both cases in IE8 and FF. Any ideas why this is happening? The relevant HTML: <div class="searchBox"> <div class="boxhead"> <h2></h2> </div> <div class="boxbody"> <div id="searchToggle" name="searchToggle"> </div> </div> </div> The relevant CSS: .searchBox { margin: 0 auto; width: 700px; background: url(/images/myImageRight-r.gif) no-repeat bottom right; font-size: 100%; text-align: left; overflow: hidden; } .boxbody { margin: 0; padding: 5px 30px 31px; background-image: url(/images/myImageLeft.gif); background-repeat: no-repeat; background-position: left bottom; }

  • CSS to specify positions over a scanned document

    - by itsols
    I'm trying to write the CSS rules to position text over a scanned document. Reason: The document is a pre-printed form. I am trying to position the text on-screen so that it relates to the 'spaces' on the actual form. Issue: Although I position the values using centimeters, they don't seem to get aligned with the ones on the actual page. I can see this misalignment since my scanned image is in the background of the page. What I've tried: I used a ruler to physically measure the locations and specify them with CSS. But on-screen, it doesn't tally. I used the scanned image to position the CSS values. Then the printout is not correct. I even scaled the scanned page using Inkscape to the exact dimensions in centimeters and took into account all margins, etc... What I need: I am trying to correctly show the output values on-screen AND have them print in the correct manner as well. I know that using two CSS sheets (one for print) is an option. But I'm developing this program away from where the actual printing is to be done. So is there a convenient way of matching the exact screen locations with those on the actual/final prinout? Thanks!

  • Advise guidance on how to form this jQuery script for show/hide fade element

    - by Rick
    Hey guys.. I basically have several links on the left side of the screen and on the right is a preview window. Below the preview window is another box for the affiliate link code. So what I am trying to do is create an affiliate page where you choose the banner size on the left by clicking on the link and on the right you see it dynamically change to the banner size and the code changes accordingly as well. So far I have the following code and it works but it seems very very cumbersome and bloated. Can you see if I can trim this down? jQuery(".banner-style li").click(function() { jQuery(".banner-style li").removeClass("selected"); jQuery(this).addClass("selected"); var $banner = jQuery(this).attr("class"); $banner = $banner.replace(" selected",""); jQuery(".preview img").fadeOut('fast',function() { jQuery(".preview img").attr("src", "http://localhost/site/banners/"+$banner+".jpg") .fadeIn('slow'); }); jQuery(".code p").removeClass('hide').hide(); jQuery(".code p."+$banner).show(); }); Also to note the funny thing is in FF, when you click for the first to on any link, the original image on the right fades out and in real quick and then it loads the "clicked" image. This does not happen in other browsers...

    I have two ordered lists and user can move items between them. I am using jQuery UI's Selectable for both of them.

  • How to "reset" subviews of scrollview for new items?

    - by Tom Tallak Solbu
    I have a MasterViewController displaying Items. Selecting an Item (ItemA), displays images of ItemA in a DetailViewController. The DeatilViewController contains a scrollView, displaying all the images. When tableView:didSelectRowAtIndexPath is called, the images is added to an UIImageView, that is tagged and added as a subview to a scrollview. NSUInteger i; for (i = 1; i <= numberOfImages; i++) { NSString *imageName = [ItemAImages objectAtIndex:i-1]; UIImage *image = [UIImage imageNamed:imageName]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.tag = i; [scrollView addSubview:imageView]; } Works fine. But when I go back to the MasterViewController, and selects a ItemB, the ItemA is still displayed, like the iPhone simulator refuses to forget the previous scrollview,containing ItemA images. I have tried [subview removeFromSuperview]; which results in either no scrollview at all, or no effect. Depending on when this method is called. How can I "reset" the scrollview for the next Item?

    I'm trying to display a grid of items, with each item having a photo on the left and a description on the right, something like this: ---------------------------- | photo | item description | ---------------------------- I want to display these items in a 3x3 grid on the page. I have the grid part worked out, what I'm having trouble with is alignment of the photo and description. When the height of the description exceeds the height of the photo, I don't want the text to wrap under the photo. I essentially want to maintain two separate columns. I have tried this: .item{ padding-left: 60px; // size of photo + 5px margin background-position: 5px 0px; } <div class="item" style="background-image: url('/img/photo123.jpg');"> Here is the item description </div> That has worked very well. the markup is clean and I don't have to mess around with absolute/relative, however, now I can't add a border to the image. Can anyone suggest a workaround or alternative?

  • Cannot change font size /type in plots

    - by Sameet Nabar
    I recently had to re-install my operating system (Ubuntu). The only thing I did differently is that I installed Matlab on a separate partition, not the main Ubuntu partition. After re-installing, the fonts in my plots are no longer configurable. For example, if I ask the title font to be bold, it doesn't happen. I ran the sample code below on my computer and then on my colleague's computer and the 2 results are attached. This cannot be a problem with the code; rather in the settings of Matlab. Could somebody please tell me what settings I need to change? Thanks in advance for your help. Regards, Sameet. x1=-pi:.1:pi; x2=-pi:pi/10:pi; y1=sin(x1); y2=tan(sin(x2)) - sin(tan(x2)); [AX,H1,H2]=plotyy(x1,y1,x2,y2); xlabel ('Time (hh:mm)'); ylabel (AX(1), 'Plot1'); ylabel (AX(2), 'Plot2'); axes(AX(2)) set(H1,'linestyle','none','marker','.'); set(H2,'linestyle','none','marker','.'); title('Plot Title','FontWeight','bold'); set(gcf, 'Visible', 'off'); [legh, objh] = legend([H1 H2],'Plot1', 'Plot2','location','Best'); set(legend,'FontSize',8); print -dpng Trial.png; Bad image: http://imageshack.us/photo/my-images/708/trial1u.png/ Good image: http://imageshack.us/photo/my-images/87/trial2.png/

  • Newbie: Render RGB to GTK widget -- howto?

    - by Billy Pilgrim
    Hi All, Big picture: I want to render an RGB image via GTK on a linux box. I'm a frustrated GTK newbie, so please forgive me. I assume that I should create a Drawable_area in which to render the image -- correct? Do I then have to create a graphics context attached to that area? How? my simple app (which doesn't even address the rgb issue yet is this: int main(int argc, char** argv) { GdkGC * gc = NULL; GtkWidget * window = NULL; GtkDrawingArea * dpage = NULL; GtkWidget * page = NULL; gtk_init( &argc, & argv ); window = gtk_window_new( GTK_WINDOW_TOPLEVEL ); page = gtk_drawing_area_new( ); dpage = GTK_DRAWING_AREA( page ); gtk_widget_set_size_request( page, PAGE_WIDTH, PAGE_HEIGHT ); gc = gdk_gc_new( GTK_DRAWABLE( dpage ) ); gtk_widget_show( window ); gtk_main(); return (EXIT_SUCCESS); } my dpage is apparently not a 'drawable' (though it is a drawing area). I am confused as to a) how do I get/create the graphics context which is required in subsequent function calls? b) am I close to a solution, or am I so completely *#&@& wrong that there is no hope c) a baby steps tutorial. (I started with hello world as my base, so I got that far). any and all help appreciated. bp
