  • Images inside of UILabel

    - by enby
    hello everyone! I'm trying to find the best way to display images inside of UILabels (in fact, I wouldn't mind switching to something other than UILabel if it supports images with no hassle) The scenario is: I have a table view with hundreds of cells and UILabel being the main component of each cell The text I assign to each cell contains sequences of characters that need to be parsed out and represented as an image In simpler words, imagine a TableView of an instant messenger that parses replaces all ":)", ":(", ":D" etc with corresponding smiley images Any input would be greatly appreciated!

  • Error:A generic error occurred in GDI+

    - by sanfra1983
    Hi, I created a web project on the server, and when I upload an image shows me the error Error: A generic error occurred in GDI +. I have read many links on the net that talk about this issue, and although I made the changes, nothing went wrong. I was thinking if the case is not an issue of permissions to folders. In fact I have two folders one inside the other. This is the code to resize the image: public Bitmaps ResizeImage (Stream stream, int? width, int? height) ( System.Drawing.Bitmap bmpOut = null; const int defaultWidth = 800; const int defaultHeight = 600; int width = lnWidth == null? defaultWidth: (int) width; int height = lnHeight == null? defaultHeight: (int) height; try ( LoBMP bitmap = new Bitmap (stream); ImageFormat loFormat = loBMP.RawFormat; decimal lnRatio; lnNewWidth int = 0; lnNewHeight int = 0; if (loBMP.Width <& & lnWidth loBMP.Height <lnHeight) ( loBMP return; ) if (loBMP.Width> loBMP.Height) ( lnRatio = (decimal) lnWidth / loBMP.Width; lnNewWidth = lnWidth; decimal = lnTemp loBMP.Height lnRatio *; lnNewHeight = (int) lnTemp; ) else ( lnRatio = (decimal) lnHeight / loBMP.Height; lnNewHeight = lnHeight; decimal = lnTemp loBMP.Width lnRatio *; lnNewWidth = (int) lnTemp; ) bmpOut = new Bitmap (lnNewWidth, lnNewHeight); Graphics g = Graphics.FromImage (bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.FillRectangle (Brushes.White, 0, 0, lnNewWidth, lnNewHeight); g.DrawImage (loBMP, 0, 0, lnNewWidth, lnNewHeight); loBMP.Dispose (); ) catch ( return null; ) bmpOut return; ) and this is the code that I insert in the codebehind: string filepath = AppDomain.CurrentDomain.BaseDirectory + img_veterinario / "; string = filepathM AppDomain.CurrentDomain.BaseDirectory + img_veterinario / img_veterinarioM; Reseize Reseize R = new (); Bitmap = photosFileOriginal r.ResizeImage (fucasiclinici.PostedFile.InputStream, 400, 400); Bitmap = photosFileMiniatura r.ResizeImage (fucasiclinici.PostedFile.InputStream, 72, 72); String filename = Path.GetFileName (fucasiclinici.PostedFile.FileName); photosFileOriginal.Save (Path.Combine (filepath, filename)); photosFileMiniatura.Save (Path.Combine (filepathM, filename)); Can you help me? Thanks

  • how can I change top-margin the right way if multiple css class assigned?

    - by Radek
    I assigned these classes menu second_menu menu_about_author to ul so the html code looks like <ul class="menu second_menu menu_about_author"> I wanted this ul to have the same properties like menu and second_menu and then I wanted to move the menu_about_author little bit down. I did so by .menu_about_author { margin-top:40px; } but it didn't work any idea why the margin-top:40px; is crossed? the link to the image is [1]: http://img153.imageshack.us/img153/882/58daeef0c3c846e4a8d6321.png

  • vagrant box add: where does .box file get downloaded to?

    - by Calvin Cheng
    What actually happens to the .box file (which according to the docs is simply a vbox image in tar form, in a particular format) after the first command vagrant box add lucid32 http://files.vagrantup.com/lucid32.box is executed? I can't seem to find the filesystem location of lucid32.box after the download has successfully completed... I am aware it doesn't really matter as vagrant init lucid32 vagrant up vagrant ssh will get me into the vm irregardless. But I am curious where .box is located.

  • Android browser touch events stop display being updated inc. canvas/elements - How to work around?

    - by Ed Kirk
    On some android's native browser touching the page seems to stop the display from being updated until the finger is released. This occurs for both html element based animation (switching classes) and for canvas based animation. It does not however stop normal js execution and other events are fired as normal. On devices with this problem the dolphin browser also seems effected (not firefox though). Touchstart/move both have preventDefault() fired as well as stopPropergation(), cancelBubble = true; and e.returnValue = false;. In the CSS webkit selection has also been disabled. The page will not scroll. A similar question has been asked here: Does Android browser lock DOM on touchStart? but I'd like to find out if this behaviour can be overcome, or at least to discover what devices will be effected by the problem, is it a device or version android issue? If you cannot answer the question running the demo and reporting your experience along with your device model and useragent (displayed at bottom of demo page) as a comment might help others or myself answer the question. Here is a demo and steps to reproduce the behaviour. A QR code for the link can be found here https://s3-eu-west-1.amazonaws.com/canvas-test-pd/tmp.png. https://s3-eu-west-1.amazonaws.com/canvas-test-pd/index.html The web page has a canvas at the top and a div with a background image at the bottom. Every second the canvas is cleared and a different image displayed and the div has it's class switched (both toggle between 0 and 1 pngs). Once this has toggled a few times place your finger on the canvas (the top grey box) and hold it there. Wait to see if the animation continues (sometimes it will once or twice then stops) and if there are any visual distortions. Update It seems that the Galaxy Tab running 3.2 requires handlers for touchstart/end of document, not just required divs for the screen to continue updating the display. Thanks jimpic. I'm starting to believe it's an issue caused by manufacturers skins, although this is difficult to prove.

  • .net compact framework backward compatibility 3.5 and 2.0

    - by mack369
    Do I need to install .net 2.0 on the device, where .net 3.5 is installed? So far my application works on .net 2.0 (which potentially should be faster) but the long term plan is to port it to .net 3.5. I need to order devices and the OEM needs to know which version of .net should be add to Windows CE image (version 5.0). Shall I ask him to add both .net 2.0 and .net 3.5 ?
