  • How can I retain the editing in the tableView of the search result with UISearchDisplayController?

    - by wal
    I want to search a table in editing mode, but when I type a letter the variable tableView.editing is changed to NO. And when I cancel the search, the tableView.editing return to YES. I'd like to retain the editing YES in the result of the search. I put breakpoint in several methods. Until the filterContentForSearchText method, the variable is YES, but in the cellForRowAtIndexPath, it is NO. Image of the table in editing mode just before type a letter in the search bar.

  • getting window screenshot windows API

    - by Oliver
    Hi, I am trying to make a program to work on top of an existing GUI to annotate it and provide extra calculations and statistical information. I want to do this using image recognition, as I have learned a fair amount about this in University using Matlab and similar things. I can get a handle to the window I want to perform image recognition on, but I don't know how to turn that handle into an image of that window, and all its visible child windows. I suppose I am looking for something like the screenshot function, but restricted to a single window. How would I go about doing this? I suppose I'd need something like a .bmp to mess about with. Also, it would have to be efficient enough that I could call it several times a second without my PC grinding to a halt. Hopefully this isn't an obvious question, I typed some things into google but didn't get anything related.

  • How can I unbind JQZOOM in my JQuery Script?

    - by Andy Barlow
    Hello, I have this script at the moment, which changes an image when a thumbnail has been changed. I then want JQZOOM to be added to that new image. However, if I put it inside the Onclick event, it gets slower and slower the more times you click on it... I guess because its running multiple instances. Is there anyway to unbind the JQZOOM from something then rebind it to something else? Here is my jquery at the moment: var options = { zoomWidth: 400, zoomHeight: 325, xOffset: 25, yOffset: 0, position: "right", lens: true, zoomType: "reverse", imageOpacity: 0.5, showEffect: "fadein", hideEffect: "fadeout", fadeinSpeed: "medium", title: false }; $('.jqzoom').jqzoom(options); $('.single-zoom-image').click ( function () { $('#bigProductImage').attr("src", $(this).attr("zoom")); $('.jqzoom').attr("href", $(this).attr("extrazoom")); }); Thanks in advance if anyone can help me. Cheers!

  • Flex datagrid multiple rows single file

    - by Vish
    Hi, I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.. Thanks, Vish.

    Hi, I've customized my UINavigationBar with an image like that : @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"NavigationBar.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end When I launch a video my custom NavigationBar (with the picture) is on the top or I would like to have the default navigationBar style when I'm playing a video. I tried to hide the navigationBar with [self.navigationController setNavigationBarHidden:YES animated:animated]; but it just remove the navigationBar in my controller but I still have the NavigationBar.png when I'm playing a video. I tried to set the barstyle but it doesn't work either ... self.navigationController.navigationBar.barStyle = UIBarStyleDefault; Could you help me ?

  • If/else isn't working properly

    - by luckytaxi
    I have a validation function I'm using inside of codeigniter. function valid_image() { if ( ($_FILES["file"]["type"] != "image/jpeg") || ($_FILES["file"]["type"] != "image/gif") ) { $this->form_validation->set_message('valid_image', 'Wrong file type..'); return false; } else { return true; } With just the "image/jpeg" part in the if statement it works fine. If I try to upload anything other than a jpg file it fails. If I run the code above, it fails with both a jpg or a gif file. And before someone says "why not use the upload class," I can't. I'm saving my pics directly into MongoDB, so the upload class doesn't help much.

  • Edit a video to embed a bitmap.

    - by Rajkumar R
    I would like to edit a video so that i can embed a small bitmap image at any corner. The bitmap image has to be replaced with another image, for every two video frames. If somehow it is possible to covert a group of pictures into slideshow video then i want that video to be embedded at the corner of the main video. The size of the bitmap is about the size of a channel logo and that is exact space it will occupy in the video. Please guide me in accomplishing. Is there any existing libraries available to do this. I am working on .Net 4 platform but i do

  • Help need to with MySQL query to join data spanning multiple tables and use data as column names

    - by gurun8
    I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset aren't really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results than it did for me to assemble this question. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

  • Adding a dynamic-height UITableView into a scrolling view?

    - by Greg
    Hello all – I'm getting into iPhone development and have hit my first confusing UI point. Here's the situation: My app is tab-based, and the view that I'm confused about has a static featured content image at the top, then a dynamic list below into which X headlines are loaded. My goal is to have the height of the headline table grow as elements are added to it, and then to have the whole view scroll (both featured image on top and headline list below). So, I guess my question comes in two parts: 1) First, how do you set up a dynamic-height table view that will grow as cells are added to it. So far I've only been able to have my tables handle their own scrolling. 2) Then, what is the root NIB view that the featured image and the table should live in to enabled scrolling? I've dropped oversized content into a UIScrollView now, although did seem to have any success with having it automatically scroll. Thanks in advance for any help on this subject!

  • Call function under object from string

    - by sam
    I have a script which creates a drag-and-drop uploader on the page from a div. My DIV will look something like <div class="well uploader" data-type="image" data-callback="product.addimage" data-multi="1"></div> Then I'll have a function something like var product = new function(){ /* Some random stuff */ this.addimage = function(image){ alert('W00T! I HAZ AN IMAGE!'); } /* More random stuff */ } When the upload is complete, I need to call the function in data-callback (In this example, product.addimage). I know with global functions you can just do window[callback]() but I'm not sure the best way to do this with functions under objects. My first thought was to do something like* var obj = window; var parts = callback.split('.'); for(part in parts){ obj = obj[parts[part]]; } obj(); but that seems a bit dirty, is there a better way without using eval because eval is evil? I haven't tested this so I have no idea if it will work

  • how to write barcode in html format when using tcpdf

    - by JewelThief
    I am using TCPDF to generate PDF file using following command $pdf-writeHTML($htmlcontent, true, 0, true, 0); TCPDF also provides a way to create barcode with following commands $pdf-Cell(0, 0, 'C39+', 0, 1); $pdf-write1DBarcode('Code 39', 'C39+', '', '', 80, 15, 0.4, $style, 'N'); $pdf-Ln(); I want to be able to write barcode as part of the HTML code above. Is there easy way? I can potentially call a barcode image inthe writeHTML code above, but not sure how to use above barcode function ( or any in TCPDF) which would allow me to create image and then get that image into HTML generation

  • Altering CSS for nav bar images to accomodate IE

    - by Kim
    My horizontal nav bar is populated with images for the links that are coming from one image that includes all the sub-images; each nav item image is identified by the pixel location within the larger image. This works perfectly fine in Firefox and Safari, but in IE, all of the images are misplaced too low within the nav bar (can only barely see the tops of the words). Two questions: How do I fix this in the css so it is back-compatible with the more recent versions (and current versions) of IE Do I need a separate IE stylesheet? Thanks!

  • Detecting bad jpeg images

    - by Gerard Cerchio
    The question on validating jpegs on network transfer is very helpful. Could we take this question one step further? What if the image data is incomplete or corrupt from the server? The complete transport works, the MIME type is image/jpeg, the UIImage is constructed and non-nil but the renderer discovers inconsistencies in the data and the log shows "Bad Huffman code" or "premature end of data segment" How would I capture this error before tossing the UIImage into the view context and thereby getting a not-pretty image on the screen? Could I render it to a non-screen context and capture the error?

  • OnPage Load display one sentence - hide others

    - by Paul
    Hi I have created http://techavid.com/design/test3.html and when you load the page you see there are 3 images. The sun image is focused(in color), while the others are greyed out until clicked. That is how it should be for the images. Under each image you see a sentence 1st: Sun, 2nd: Airplane & 3rd: Nano, but when page loads you see all three sentences. How to make it so when page loads the first sentence underneath the active image (sun) shows only and the others do not show, they only show when clicked (though that works just need to figure out onpage load only show "1st: Sun")? thanks :) paul J.

  • button inside table view cell shows highlighted state on tapping on cell

    - by Vivek Dandage
    Hi there! I have an issue with the background image of button which is dependent of button state. I have a button inside customized table view cell and i have set different images for button's different states. Please look into the code below. [btnNow setImage:[UIImage imageNamed:@"now_norm.png"] forState:UIControlStateNormal]; [btnNow setImage:[UIImage imageNamed:@"now_focus.png"] forState:UIControlStateHighlighted]; Whenever i tap on the actual button this works great but if i tap on area outside of button but which is still inside that same cell then this button changes its background image from UIControlStateNormal to UIControlStateHighlighted. If i remove background image from UIControlStateHighlighted state then this issue doesn't exists but i need pressed state of the button. Please help me out. Thanks in advance! Vivek Dandage.

  • Scala Lift - Robust method to protect files from hotlinking

    - by sirjamm
    I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)

  • jQuery Animate width to the left and up

    - by efru
    Hi all- I'm trying to animate an image's width and height properties. Currently the image (as expected) animates to the right and down, however I'd like for the animation to occur to the left and upwards. Here's my current code : http://jsfiddle.net/7UbYy/ I've read a few other posts on this subject which all refer to setting a marginLeft or left property but I can't seem to get the desired effect. I need the image to animate to the left and upwards while remaining in place. Let me know if this is possible...I can't seem to think of a way to do it right now.. Thanks in advance. Appreciate it.

  • Why does UIImageView "darken"/saturate PNG images, and can I stop it?

    - by Ben
    I have a PNG file in a UIImageView, and next to that I have an EAGLView which displays the continuation of that same image (long story) as a texture, carved from the same original PNG. The point is, that these images, which should match up flawlessly, actually have somewhat differing color saturation. Normally I'd blame my handling of the PNG texture load in GL, but when I hold Preview (with the PNG) up to the iPhone simulator, it's GL that's spot on, and the UIImageView that's wrong! It's taken the image and made it ever-so-slightly more saturated. The image view is opaque with 100% alpha. I verified this on a clean UIImageView with another PNG file when put next to Preview. Anyone know what's up?

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

    I've run into a major display problem on newly installed fedora 11, on my 6 years old pc which runs a pentium4 2.4 GHz processor, 1 gb ddr ram, intel 845 motherboard with integrated graphics card. When i open an image or play a video, my complete screen turns garbled. I simply cannot make out whats on my screen. With difficulty i have to close the image/video window and move around the folder window to clean the screen image. Is it because of my display drivers? How can i fix it? I also ran into mp3 plugins and flash issues which i was able to resovle. I'm new to linux, the sole purpose of isntalling it on my old pc was to learn linux but this display problem is frustrating me. Thanks, Salman

} Screenshot Lightmap I believe the problem comes from the difference between the lightmap uv coordinates and the pixel center coordinates...for example, here are the lightmap uv coordinates( generated by D3DXUVAtlasCreate() ) for a specific face( tri ) within the mesh, keep in mind that I'm using the mesh uv coordinates to write the pixels for the texture: v[ 0 ].uv = D3DXVECTOR2( 0.003581, 0.295631 ); v[ 1 ].uv = D3DXVECTOR2( 0.003581, 0.003581 ); v[ 2 ].uv = D3DXVECTOR2( 0.295631, 0.003581 ); the lightmap texture size is 128 x 128 pixels. The upper-left pixel center coordinates are: float halfPixel = 0.5 / 128 = 0.00390625; D3DXVECTOR2 pixelCenter = D3DXVECTOR2( halfPixel, halfPixel ); will the mapping and sampling of the lightmap texture will require that an offset be taken into account or that the uv coordinates are snapped to the pixel centers..? ...Any ideas on the best way to approach this situation would be appreciated...What are the common practices?
