Using mod_negotiation to serve webp if the UA requests it.

- by Rich Bradshaw

Is it possible to use mod_negotiation to serve up a webp image if the browser supports it, and a jpg otherwise? For instance, if I link to an image with the path /images/test, it serves the image found at /images/test.webp if the UA knows about webp, or jpg otherwise? I've tried poking around, but it seems that the Accept headers in Chrome at least look like Accept:*/*, rather than specifying the image type. If this isn't the way to do it, has anyone got any other suggestions?

Scalable images in Java

- by CodeGuy

I anticipate using some images in my Java application. These images will be drawn onto my JPanel using g.drawImage(). The JPanel is resizable and the images should scale as the JPanel increases/decreases in size Two questions: What image format is best for this type of desired scalable image? For instance, in this application, an image of size 100x100 may be scaled into an image of size 30x30 or 10x10 or 300x300. How can I write code to do this scaling?

load page with inactive scrollbar

- by atwellpub

I have a page that scrolls through images, some taller than the others. When a tall image loads it auto-creates a scrollbar in the browser window, causing a width jerk. Is there a way to load a scroll bar regardless of if it is needed, and when a tall image apears it activates itself accordingly, then deactivates its self accordingly when the image changes to a shorter image? Thank you!

Android. How do I keep a button displayed as PRESSED until the action created by that button is finished?

- by user527405

I have button_focused, button_pressed, and button_normal images. When I press the button, the button_pressed image is displayed and the action related to the button pressing begins. When I quit pressing the button, the action continues but the button returns to button_normal image being displayed. How can I set the button image being displayed to button_pressed during the entire action then reset to the button_normal image? Thank you for your time

Experience the iPad UI On Your PC

- by Matthew Guay

Want to test drive iPad without heading over to an Apple store? Here’s a way you can experience some of the iPad UI straight from your browser! The iPad is the latest gadget from Apple to wow the tech world, and people even waited in line all night to be one of the first to get their hands on one. Thanks to a simple JavaScript trick, however, you can get a feel for some of its new features without leaving your computer. This won’t let you try out everything on the iPad, but it will let you see how the new lists and pop-over menus work just like they do in the new apps. Test drive the iPad’s UI from your browser Normally, the Apple iPhone developer library online looks like a standard webpage. But, on the iPad, it looks and feels like a full-blown native iPad app. With a nifty JavaScript trick from boredzo.org you can use this same interface on your PC. Since the iPad uses the Safari browser, we ran this test in Safari for Windows. If you don’t already have it installed, you can download it from Apple (link below) and setup as normal. Now, open Safari and browse to Apple’s developer page at: http://www.developer.apple.com Now, enter the following in the address bar, and press Enter. javascript:localStorage.setItem('debugSawtooth', 'true') Finally, click this link to go to the iPhone OS documentation. http://developer.apple.com/iphone/library/iPad/ After a short delay, it should open in full iPad style! The left menu works just like the menus on the iPad, complete with transitions. It feels entirely like a native application, instead of a webpage. To scroll through text, click and pull up or down similar to the way you would use it on a touch screen. Some pages even include a pop-over menu like many of the new iPad apps use. Note that the page will be rendered for the size of your browser, and if you resize your window the page will not resize with it. Simply press F5 to reload the page, and it will resize to fit the new window size. If you resize your window to be tall and narrow, like the iPad in horizontal mode, the webpage will change and the left menu will disappear in lieu of a drop-down menu just like it would if you rotated the iPad. This works in Chrome as well, since it, like Safari, is based on Webkit. However, it didn’t seem to work in our test on Firefox or other browsers. We’ve previously covered how you can experience some of the iPhone’s UI with the online iPhone user guide. Check it out if you haven’t yet: View Mobile Websites in Windows with Safari 4 Developer Tools Conclusion Although this doesn’t let you really try out all of the iPad’s interface, it at least gives you a taste of how it works. It’s exciting to see how much functionality can be packed into webapps today. And don’t forget, How-to Geek is giving away an iPad to a random fan!

Game Object Factory: Fixing Memory Leaks

- by Bunkai.Satori

Dear all, this is going to be tough: I have created a game object factory that generates objects of my wish. However, I get memory leaks which I can not fix. Memory leaks are generated by return new Object(); in the bottom part of the code sample. static BaseObject * CreateObjectFunc() { return new Object(); } How and where to delete the pointers? I wrote bool ReleaseClassType(). Despite the factory works well, ReleaseClassType() does not fix memory leaks. bool ReleaseClassTypes() { unsigned int nRecordCount = vFactories.size(); for (unsigned int nLoop = 0; nLoop < nRecordCount; nLoop++ ) { // if the object exists in the container and is valid, then render it if( vFactories[nLoop] != NULL) delete vFactories[nLoop](); } return true; } Before taking a look at the code below, let me help you in that my CGameObjectFactory creates pointers to functions creating particular object type. The pointers are stored within vFactories vector container. I have chosen this way because I parse an object map file. I have object type IDs (integer values) which I need to translate them into real objects. Because I have over 100 different object data types, I wished to avoid continuously traversing very long Switch() statement. Therefore, to create an object, I call vFactoriesnEnumObjectTypeID via CGameObjectFactory::create() to call stored function that generates desired object. The position of the appropriate function in the vFactories is identical to the nObjectTypeID, so I can use indexing to access the function. So the question remains, how to proceed with garbage collection and avoid reported memory leaks? #ifndef GAMEOBJECTFACTORY_H_UNIPIXELS #define GAMEOBJECTFACTORY_H_UNIPIXELS //#include "MemoryManager.h" #include <vector> template <typename BaseObject> class CGameObjectFactory { public: // cleanup and release registered object data types bool ReleaseClassTypes() { unsigned int nRecordCount = vFactories.size(); for (unsigned int nLoop = 0; nLoop < nRecordCount; nLoop++ ) { // if the object exists in the container and is valid, then render it if( vFactories[nLoop] != NULL) delete vFactories[nLoop](); } return true; } // register new object data type template <typename Object> bool RegisterClassType(unsigned int nObjectIDParam ) { if(vFactories.size() < nObjectIDParam) vFactories.resize(nObjectIDParam); vFactories[nObjectIDParam] = &CreateObjectFunc<Object>; return true; } // create new object by calling the pointer to the appropriate type function BaseObject* create(unsigned int nObjectIDParam) const { return vFactories[nObjectIDParam](); } // resize the vector array containing pointers to function calls bool resize(unsigned int nSizeParam) { vFactories.resize(nSizeParam); return true; } private: //DECLARE_HEAP; template <typename Object> static BaseObject * CreateObjectFunc() { return new Object(); } typedef BaseObject*(*factory)(); std::vector<factory> vFactories; }; //DEFINE_HEAP_T(CGameObjectFactory, "Game Object Factory"); #endif // GAMEOBJECTFACTORY_H_UNIPIXELS

Juju Openstack bundle: Can't launch an instance

If it’s the first time that you hear about Microsoft All-In-One Code Framework, please read this Microsoft News Center article http://www.microsoft.com/presspass/features/2011/jan11/01-13codeframework.mspx, or watch the introduction video on YouTube http://www.youtube.com/watch?v=cO5Li3APU58, or read the introduction on our homepage http://1code.codeplex.com/. -------------- New Silverlight code samples CSSLTreeViewCRUDDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215808 The code sample was created by Amit Dey. It demonstrates a custom TreeView with added functionalities of CRUD (Create, Read, Update, Delete) and drag-and-drop operations. Silverlight TreeView control with CRUD and drag & drop is a frequently asked programming question in Silverlight forums. Many customers also requested this code sample in our code sample request service. We hope that this sample can reduce developers' efforts in handling this typical programming scenario. The following blog article introduces the sample in detail: http://blogs.msdn.com/b/codefx/archive/2011/02/15/silverlight-treeview-control-with-crud-and-drag-amp-drop.aspx. CSSL4FileDragDrop and VBSL4FileDragDrop Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215809 http://1code.codeplex.com/releases/view/62253#DownloadId=215810 The code sample demonstrates the new drag&drop feature of Silverlight 4 to implement dragging picures from the local file system to a Silverlight application. Sometimes we want to change SiteMapPath control's titles and paths according to Query String values. And sometimes we want to create the SiteMapPath dynamically. This code sample shows how to achieve these goals by handling SiteMap.SiteMapResolve event. CSASPNETEncryptAndDecryptConfiguration, VBASPNETEncryptAndDecryptConfiguration Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215027 http://1code.codeplex.com/releases/view/62253#DownloadId=215106 In this sample, we encrypt and decrypt some sensitive information in the config file of a web application by using the RSA asymmetric encryption. This project contains two snippets. The first one demonstrates how to use RSACryptoServiceProvider to generate public key and the corresponding private key and then encrypt/decrypt string value on page. The second part shows how to use RSA configuration provider to encrypt and decrypt configuration section in web.config of web application. connectionStrings section in plain text: Encrypted connectionString: Note that if you store sensitive data in any of the following configuration sections, we cannot encrypt it by using a protected configuration provider <processModel> <runtime> <mscorlib> <startup> <system.runtime.remoting> <configProtectedData> <satelliteassemblies> <cryptographySettings> <cryptoNameMapping> CSASPNETFileUploadStatus Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215028 I believe ASP.NET programmers will like this sample, because in many cases we need customers know the current status of the uploading files, including the upload speed and completion percentage and so on. Under normal circumstances, we need to use COM components to accomplish this function, such as Flash, Silverlight, etc. The uploading data can be retrieved in two places, the client-side and the server-side. For the client, for the safety factors, the file upload status information cannot be got from JavaScript or server-side code, so we need COM component, like Flash and Silverlight to accomplish this, I do not like this approach because the customer need to install these components, but also we need to learn another programming framework. For the server side, we can get the information through coding, but the key question is how to tell the client results. In this case, We will combine custom HTTPModule and AJAX technology to illustrate how to analyze the HTTP protocol, how to break the file request packets, how to customize the location of the server-side file caching, how to return the file uploading status back to the client and so on . CSASPNETHighlightCodeInPage, VBASPNETHighlightCodeInPage Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215029 http://1code.codeplex.com/releases/view/62253#DownloadId=215108 This sample imitates a system that needs display the highlighted code in an ASP.NET page . As a matter of fact, sometimes we input code like C# or HTML in a web page and we need these codes to be highlighted for a better reading experience. It is convenient for us to keep the code in mind if it is highlighted. So in this case, the sample shows how to highlight the code in an ASP.NET page. It is not difficult to highlight the code in a web page by using String.Replace method directly. This method can return a new string in which all occurrences of a specified string in the current instance are replaced with another specified string. However, it may not be a good idea, because it's not extremely fast, in fact, it's pretty slow. In addition, it is hard to highlight multiple keywords by using String.Replace method directly. Sometimes we need to copy source code from visual studio to a web page, for readability purpose, highlight the code is important while set the different types of keywords to different colors in a web page by using String.Replace method directly is not available. To handle this issue, we need to use a hashtable variable to store the different languages of code and their related regular expressions with matching options. Furthermore, define the css styles which used to highlight the code in a web page. The sample project can auto add the style object to the matching string of code. A step-by-step guide illustrating how to highlight the code in an ASP.NET page: 1. the HighlightCodePage.aspx page Choose a type of language in the dropdownlist control and paste the code in the textbox control, then click the HighLight button. 2. Display the highlighted code in an ASP.NET page After user clicks the HighLight button, the highlighted code will be displayed at right side of the page. CSASPNETPreventMultipleWindows Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215032 This sample demonstrates a step-by-step guide illustrating how to detect and prevent multiple windows or tab usage in Web Applications. The sample imitates a system that need to prevent multiple windows or tabs to solve some problems like sharing sessions, protect duplicated login, data concurrency, etc. In fact, there are many methods achieving this goal. Here we give a solution of use JavaScript, Sample shows how to use window.name property check the correct links and throw other requests to invalid pages. This code-sample use two user controls to make a distinction between base page and target page, user only need drag different controls to appropriate web form pages. so user need not write repetitive code in every page, it will make coding work lightly and convenient for modify your code. JSVirtualKeyboard Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215093 This article describes an All-In-One framework sample that demonstrates a step-by-step guide illustrating how to build a virtual keyboard in your HTML page. Sometimes we may need to offer a virtual keyboard to let users input something without their real keyboards. This scenario often occurs when users will enter their password to get access to our sites and we want to protect the password from some kinds of back-door software, a Key-logger for example, and we will find a virtual keyboard on the page will be a good choice here. To create a virtual keyboard, we firstly need to add some buttons to the page. And when users click on a certain button, the JavaScript function handling the onclick event will input an appropriated character to the textbox. That is the simple logic of this feature. However, if we indeed want a virtual keyboard to substitute for the real keyboard completely, we will need more advanced logic to handle keys like Caps-Lock and Shift etc. That will be a complex work to achieve. CSASPNETDataListImageGallery Download: http://1code.codeplex.com/releases/view/62261#DownloadId=215267 This code sample demonstrates how to create an Image Gallery application by using the DataList control in ASP.NET. You may find the Image Gallery is widely used in many social networking sites, personal websites and E-Business websites. For example, you may use the Image Gallery to show a library of personal uploaded images on a personal website. Slideshow is also a popular tool to display images on websites. This code sample demonstrates how to use the DataList and ImageButton controls in ASP.NET to create an Image Gallery with image navigation. You can click on a thumbnail image in the Datalist control to display a larger version of the image on the page. This sample code reads the image paths from a certain directory into a FileInfo array. Then, the FileInfo array is used to populate a custom DataTable object which is bound to the Datalist control. This code sample also implements a custom paging system that allows five images to be displayed horizontally on one page. The following link buttons are used to implement a custom paging system: • First • Previous • Next • Last Note We recommend that you use this method to load no more than five images at a time. You can also set the SelectedIndex property for the DataList control to limit the number of the thumbnail images that can be selected. To indicate which image is selected, you can set the SelectedStyle property for the DataList control. VBASPNETSearchEngine Download: http://1code.codeplex.com/releases/view/62253#DownloadId=215112 This sample shows how to implement a simple search engine in an ASP.NET web site. It uses LIKE condition in SQL statement to search database. Then it highlights keywords in search result by using Regular Expression and JavaScript. New Windows General code samples CSCheckEXEType, VBCheckEXEType Downloads: http://1code.codeplex.com/releases/view/62253#DownloadId=215045 http://1code.codeplex.com/releases/view/62253#DownloadId=215120 The sample demonstrates how to check an executable file type. For a given executable file, we can get 1 whether it is a console application 2 whether it is a .Net application 3 whether it is a 32bit native application. 4 The full display name of a .NET application, e.g. System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL New Internet Explorer code samples CSIEExplorerBar, VBIEExplorerBar Downloads: http://1code.codeplex.com/releases/view/62253#DownloadId=215060 http://1code.codeplex.com/releases/view/62253#DownloadId=215133 The sample demonstrates how to create and deploy an IE Explorer Bar which could list all the images in a web page.

Problem displaying tiles using tiled map loader with SFML

I've been searching fruitlessly for what I did wrong for the past couple of days and I was wondering if anyone here could help me.

Problem upgrading kernel on debian 3.1

- by exhuma

Hi, I have a quite old box in a remote server farm. So I have no direct access. Only remote SSH (and via SSH to a serial console). I haven't updated this box in ages. Now, whenever I want to install a new package, a dependency to glibc appears. Unfortunately, the install of glibc depends on a 2.6 kernel and I am running a venerable 2.4 kernel (one more reason to upgrade). The problem is, that the install of a new kernel has an indirect (over locales) dependency to glibc. So, to install glibc, I need a new kernel. For a new kernel, I need to upgrade glibc. Essentially I am blocked. What's the best way to proceed considering I have no "hardware" access? Here's a quick transcript of the upgrade process: [green:~]% sudo aptitude install linux-image-686 Reading Package Lists...

I created a custom (WPF) DataGridBoundColumn and get unexpected behaviour, what am I missing?

- by aspic

Hi, I am using a DataGrid (from Microsoft.Windows.Controls.DataGrid) to display items on and on this DataGrid I use a custom Column which extends DataGridBoundColumn. I have bound an ObservableCollection to the ItemSource of the DataGrid. Conversation is one of my own custom datatypes which a (among other things) has a boolean called active. I bound this boolean to the DataGrid as follows: DataGridActiveImageColumn test = new DataGridActiveImageColumn(); test.Header = "Active"; Binding binding1 = new Binding("Active"); test.Binding = binding1; ConversationsDataGrid.Columns.Add(test); My custom DataGridBoundColumn DataGridActiveImageColumn overrides the GenerateElement method to let it return an Image depending on whether the conversation it is called for is active or not. The code for this is: namespace Microsoft.Windows.Controls { class DataGridActiveImageColumn : DataGridBoundColumn { protected override FrameworkElement GenerateElement(DataGridCell cell, object dataItem) { // Create Image Element Image myImage = new Image(); myImage.Width = 10; bool active=false; if (dataItem is Conversation) { Conversation c = (Conversation)dataItem; active = c.Active; } BitmapImage myBitmapImage = new BitmapImage(); // BitmapImage.UriSource must be in a BeginInit/EndInit block myBitmapImage.BeginInit(); if (active) { myBitmapImage.UriSource = new Uri(@"images\active.png", UriKind.Relative); } else { myBitmapImage.UriSource = new Uri(@"images\inactive.png", UriKind.Relative); } // To save significant application memory, set the DecodePixelWidth or // DecodePixelHeight of the BitmapImage value of the image source to the desired // height or width of the rendered image. If you don't do this, the application will // cache the image as though it were rendered as its normal size rather then just // the size that is displayed. // Note: In order to preserve aspect ratio, set DecodePixelWidth // or DecodePixelHeight but not both. myBitmapImage.DecodePixelWidth = 10; myBitmapImage.EndInit(); myImage.Source = myBitmapImage; return myImage; } protected override FrameworkElement GenerateEditingElement(DataGridCell cell, object dataItem) { throw new NotImplementedException(); } } } All this works as expected, and when during the running of the program the active boolean of conversations changes, this is automatically updated in the DataGrid. However: When there are more entries on the DataGrid then fit at any one time (and vertical scrollbars are added) the behavior with respect to the column for all the conversations is strange. The conversations that are initially loaded are correct, but when I use the scrollbar of the DataGrid conversations that enter the view seems to have a random status (although more inactive than active ones, which corresponds to the actual ratio). When I scroll back up, the active images of the Conversations initially shown (before scrolling) are not correct anymore as well. When I replace my custom DataGridBoundColumn class with (for instance) DataGridCheckBoxColumn it works as intended so my extension of the DataGridBoundColumn class must be incomplete. Personally I think it has something to do with the following: From the MSDN page on the GenerateElement method (http://msdn.microsoft.com/en-us/library/system.windows.controls.datagridcolumn.generateelement%28VS.95%29.aspx): Return Value Type: System.Windows. FrameworkElement A new, read-only element that is bound to the column's Binding property value. I do return a new element (the image) but it is not bound to anything. I am not quite sure what I should do. Should I bind the Image to something? To what exactly? And why? (I have been experimenting, but was unsuccessful thus far, hence this post) Thanks in advance.

How to toggle a WPF Grid column visibility

- by serialhobbyist

I'm having some trouble getting this to work in a WPF app I'm working on. Basically, what I'm after is something like the Task pane in an MMC: The app has three columns in the main part of the display. I need a column on the right side which is resizable. I presume this means using a Grid with a GridSplitter but anything that works will do. I want to be able to save the width of the right-side column when the app is closed and load it when the app is opened but this should be an initial size: the user should be able to resize it. When I resize the window, I want the left- and right-side columns to stay the same size and the middle column to resize with the window width. The left- and right-side columns need to have a minimum width. When I resize the right-side column I want the centre column to get smaller but not the left-side column. I also want to be able to toggle the visibility of the right-side column with a toggle button which is outside the column and when it returns to visibility I want it to be the same width it was before. I'm trying to do as much as possible in XAML and with binding. And can I have it topped with cream, ice cream and chocolate chips, please? :-)

Saving UIImagePickerController images to Core Data without crashing

- by Gordon Fontenot

I have been trying to minimize my memory footprint with UIImagePickerController, but I'm starting to think that the memory problems I am having are resulting from poor memory management, instead of a particular way to handle the UIImagePickerController object. My workflow is this: The "Edit Image" button is clicked, which presents a UIActionSheet. This action sheet allows you to delete, take a picture, choose from the library, or cancel. If you select Choose from the library or Take Picture, I alloc an instance of UIImagePickerController and present it, followed by a release of UIImagePickerController: -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (actionSheet.tag != 999) { UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; BOOL pickImage = nil; if (actionSheet.tag == iPhoneWithDelete) { switch (buttonIndex) { case 0: object.objectImage = nil; pickImage = NO; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; pickImage = YES; break; case 2: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPhoneNoDelete) { switch (buttonIndex) { case 0: imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; pickImage = YES; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPodWithDelete) { switch (buttonIndex) { case 0: object.objectImage = nil; pickImage = NO; break; case 1: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } else if (actionSheet.tag == iPodNoDelete) { switch (buttonIndex) { case 0: imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; pickImage = YES; break; default: pickImage = NO; break; } } if (pickImage) { imagePicker.allowsEditing = YES; [self presentModalViewController:imagePicker animated:YES]; } else { [self setupImageButton]; [self setupChooseImageButton]; } [imagePicker release]; } } Once I get a selection back from the UIImagePickerController, I save 2 images, a resized version of the edited image to use for a thumbnail, and a 800x600 version of the original unedited image into a relationship attribute (Transformational, using the same UIImage to PNG transformations found in the Recipes demo code) for display use: (the resize methods are based on the one demoed in this SO post.) - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [self dismissModalViewControllerAnimated:YES]; NSManagedObject *oldImage = object.imageFull; if (oldImage != nil) { [object.managedObjectContext deleteObject:oldImage]; } NSManagedObject *image = [NSEntityDescription insertNewObjectForEntityForName:@"Image" inManagedObjectContext:object.managedObjectContext]; object.imageFull = image; UIImage *rawImage = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; CGSize size = CGSizeMake(800, 600); UIImage *fullImage = [UIImageManipulator scaleImage:rawImage toSize:size]; [image setValue:fullImage forKey:@"imageFull"]; UIImage *processedImage = [UIImageManipulator scaleImage:[info objectForKey:@"UIImagePickerControllerEditedImage"] toSize:CGSizeMake(75, 75)]; object.objectImage = processedImage; [self setupImageButton]; [self setupChooseImageButton]; rawImage = nil; fullImage = nil; processedImage = nil; } When I go through viewDidUnload I am setting self.object = nil, and [object release] during dealloc, but I'm still getting memory warnings after about 10 image changes, with a crash at around 20. It leads me to believe that I am not getting that full image out of memory the correct way. What am I missing here? And on a second note, does the Camera source use significantly more memory than the Photo Albums source? I tend to get more crashes when using the camera.

Deserializing Metafile

- by Kildareflare

I have an application that works with Enhanced Metafiles. I am able to create them, save them to disk as .emf and load them again no problem. I do this by using the gdi32.dll methods and the DLLImport attribute. However, to enable Version Tolerant Serialization I want to save the metafile in an object along with other data. This essentially means that I need to serialize the metafile data as a byte array and then deserialize it again in order to reconstruct the metafile. The problem I have is that the deserialized data would appear to be corrupted in some way, since the method that I use to reconstruct the Metafile raises a "Parameter not valid exception". At the very least the pixel format and resolutions have changed. Code use is below. [DllImport("gdi32.dll")] public static extern uint GetEnhMetaFileBits(IntPtr hemf, uint cbBuffer, byte[] lpbBuffer); [DllImport("gdi32.dll")] public static extern IntPtr SetEnhMetaFileBits(uint cbBuffer, byte[] lpBuffer); [DllImport("gdi32.dll")] public static extern bool DeleteEnhMetaFile(IntPtr hemf); The application creates a metafile image and passes it to the method below. private byte[] ConvertMetaFileToByteArray(Image image) { byte[] dataArray = null; Metafile mf = (Metafile)image; IntPtr enhMetafileHandle = mf.GetHenhmetafile(); uint bufferSize = GetEnhMetaFileBits(enhMetafileHandle, 0, null); if (enhMetafileHandle != IntPtr.Zero) { dataArray = new byte[bufferSize]; GetEnhMetaFileBits(enhMetafileHandle, bufferSize, dataArray); } DeleteEnhMetaFile(enhMetafileHandle); return dataArray; } At this point the dataArray is inserted into an object and serialized using a BinaryFormatter. The saved file is then deserialized again using a BinaryFormatter and the dataArray retrieved from the object. The dataArray is then used to reconstruct the original Metafile using the following method. public static Image ConvertByteArrayToMetafile(byte[] data) { Metafile mf = null; try { IntPtr hemf = SetEnhMetaFileBits((uint)data.Length, data); mf = new Metafile(hemf, true); } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } return (Image)mf; } The reconstructed metafile is then saved saved to disk as a .emf (Model) at which point it can be accessed by the Presenter for display. private static void SaveFile(Image image, String filepath) { try { byte[] buffer = ConvertMetafileToByteArray(image); File.WriteAllBytes(filepath, buffer); //will overwrite file if it exists } catch (Exception ex) { System.Windows.Forms.MessageBox.Show(ex.Message); } } The problem is that the save to disk fails. If this same method is used to save the original Metafile before it is serialized everything is OK. So something is happening to the data during serialization/deserializtion. Indeed if I check the Metafile properties in the debugger I can see that the ImageFlags, PropertyID, resolution and pixelformats change. Original Format32bppRgb changes to Format32bppArgb Original Resolution 81 changes to 96 I've trawled though google and SO and this has helped me get this far but Im now stuck. Does any one have enough experience with Metafiles / serialization to help..? EDIT: If I serialize/deserialize the byte array directly (without embedding in another object) I get the same problem.

Optimize CUDA with Thrust in a loop

- by macs

Given the following piece of code, generating a kind of code dictionary with CUDA using thrust (C++ template library for CUDA): thrust::device_vector<float> dCodes(codes->begin(), codes->end()); thrust::device_vector<int> dCounts(counts->begin(), counts->end()); thrust::device_vector<int> newCounts(counts->size()); for (int i = 0; i < dCodes.size(); i++) { float code = dCodes[i]; int count = thrust::count(dCodes.begin(), dCodes.end(), code); newCounts[i] = dCounts[i] + count; //Had we already a count in one of the last runs? if (dCounts[i] > 0) { newCounts[i]--; } //Remove thrust::detail::normal_iterator<thrust::device_ptr<float> > newEnd = thrust::remove(dCodes.begin()+i+1, dCodes.end(), code); int dist = thrust::distance(dCodes.begin(), newEnd); dCodes.resize(dist); newCounts.resize(dist); } codes->resize(dCodes.size()); counts->resize(newCounts.size()); thrust::copy(dCodes.begin(), dCodes.end(), codes->begin()); thrust::copy(newCounts.begin(), newCounts.end(), counts->begin()); The problem is, that i've noticed multiple copies of 4 bytes, by using CUDA visual profiler. IMO this is generated by The loop counter i float code, int count and dist Every access to i and the variables noted above This seems to slow down everything (sequential copying of 4 bytes is no fun...). So, how i'm telling thrust, that these variables shall be handled on the device? Or are they already? Using thrust::device_ptr seems not sufficient for me, because i'm not sure whether the for loop around runs on host or on device (which could also be another reason for the slowliness).

java gui changing picture causes heapspace error

- by pie154

I have a java programme than when a button is clicked it updates the image on screen to the according image. this will work for the first 15 or so clicks then it causes a java heapspace error. I think it is because of the way I am updating the jpanel that contains the bufferedimage but not sure what the reason is. My code to get make the JPanel contain the new image is, public class extraScreenPanel { static JPanel screenPanel = new JPanel(new BorderLayout()); public static JPanel extraScreenPanel(int dispNum) { JLabel label = new JLabel("" + dispNum + ""); label.setPreferredSize(new Dimension(800, 600)); //label.setUI( new VerticalLabelUI(true) ); label.setVerticalAlignment( SwingConstants.TOP ); screenPanel = imgDisp(dispNum); label.setForeground(Color.white); label.setFont(new Font("Serif", Font.BOLD, 200)); screenPanel.add(label, BorderLayout.PAGE_END ); return screenPanel; } public static JPanel imgDisp(int picNum) { /* String url[] = new String[5000]; String part1; url[0] = "C:/PiPhotoPic/pic16.jpg"; for(Integer i=1;i<5000;i++){ if(i<10){part1 = "C:/temp/new0000000";} else if(i<100){part1 = "C:/temp/new000000";} else if(i<1000){part1 = "C:/temp/new00000";} else {part1 = "C:/temp/new00000";} String num = Integer.toString(i); url[i]= part1 + num + ".jpg"; } if(picNum<0){picNum=0;} String ref = url[picNum];*/ //this code is just to get specific ref for image location BufferedImage loadImg = loadImage(ref); JImagePanel panel = new JImagePanel(loadImg, 0, 0); panel.setPreferredSize(new Dimension(800, 600)); return panel; } public static class JImagePanel extends JPanel{ private BufferedImage image; int x, y; public JImagePanel(BufferedImage image, int x, int y) { super(); this.image = image; this.x = x; this.y = y; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(image, x, y, null); } } public static BufferedImage loadImage(String ref) { BufferedImage bimg = null; try { bimg = javax.imageio.ImageIO.read(new File(ref)); } catch (Exception e) { e.printStackTrace(); } BufferedImage bimg2 = resize(bimg,800,600); return bimg2; } public static BufferedImage resize(BufferedImage img, int newW, int newH) { int w = img.getWidth(); int h = img.getHeight(); BufferedImage dimg = dimg = new BufferedImage(newW, newH, img.getType()); Graphics2D g = dimg.createGraphics(); g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR); g.drawImage(img, 0, 0, newW, newH, 0, 0, w, h, null); g.dispose(); return dimg; } } And the code that updates my gui is, it works by removing the panel from its containg panel and then readding it to it. picPanel = imgDisp.imgDisp(num); repaintPicPanel(); public static void repaintPicPanel() { picPanel.removeAll(); menuPanel.remove(picPanel);; menuPanel.add(picPanel, BorderLayout.LINE_START); }

C# DotNetNuke Module: GridVIew AutoGenerateEditButton is skipping over a field on update.

- by AlexMax

I have a GridView with an automatically generated Edit button. I wanted some customized behavior for the Image column, since I wanted it to be a drop down list of items as opposed to a simple input field, and I also wanted some nice "fallback" in case the value in the database didn't actually exist in the drop down list. With the code I have done so far, I have gotten the behavior I desire out of the Image field. The problem is that when i attempt to update that particular field, I get an error spit out back at me that it can't find a method to update the form with: ObjectDataSource 'objDataSource' could not find a non-generic method 'UpdateDiscovery' that has parameters: ModuleId, Visible, Position, Title, Link, ItemId. That's not good, because I DO have an UpdateDiscovery method. However, between Title and Link, there is supposed to be another param that belongs to the Image field, and it's not being passed. I realize that it's probably the update button doesn't know to pass that field, since it's a TemplateField and not a BoundField, and when I use Bind('image') as the selected value for the drop down list, it seems to update fine...but only as long as the field in the database when I try and edit the row actually exists, otherwise it bombs out and gives me an error about the value not existing in the drop down list. I have the following GridView defined: <asp:GridView ID="grdDiscoverys" runat="server" DataSourceID="objDataSource" EnableModelValidation="True" AutoGenerateColumns="false" AutoGenerateEditButton="true" AutoGenerateDeleteButton="true" DataKeyNames="ItemId" OnRowDataBound="cmdDiscovery_RowDataBound"> <Columns> <asp:BoundField DataField="ItemId" HeaderText="#" ReadOnly="true" /> <asp:BoundField DataField="Visible" HeaderText="Visible" /> <asp:BoundField DataField="Position" HeaderText="Position" /> <asp:TemplateField HeaderText="Image"> <ItemTemplate> <asp:Label ID="lblViewImage" runat="server" /> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlEditImage" runat="server" title="Image" DataValueField="Key" DataTextField="Value" /> </EditItemTemplate> </asp:TemplateField> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField DataField="Link" HeaderText="Link" /> </Columns> </asp:GridView> The datasource that this is tied to: <asp:ObjectDataSource ID="objDataSource" runat="server" TypeName="MyCompany.Modules.Discovery.DiscoveryController" SelectMethod="GetDiscoverys" UpdateMethod="UpdateDiscovery" DeleteMethod="DeleteDiscovery"> <SelectParameters> <asp:QueryStringParameter Name="ModuleId" QueryStringField="mid" /> </SelectParameters> <UpdateParameters> <asp:QueryStringParameter Name="ModuleId" QueryStringField="mid" /> </UpdateParameters> <DeleteParameters> <asp:QueryStringParameter Name="ModuleId" QueryStringField="mid" /> </DeleteParameters> </asp:ObjectDataSource> The cmdDiscovery_RowDataBound method that gets called when the row's data is bound is the following C# code: protected void cmdDiscovery_RowDataBound(object sender, GridViewRowEventArgs e) { try { if (e.Row.RowIndex >= 0) { int intImage = ((DiscoveryInfo)e.Row.DataItem).Image; if (grdDiscoverys.EditIndex == -1) { // View Label lblViewImage = ((Label)e.Row.FindControl("lblViewImage")); if (GetFileDictionary().ContainsKey(intImage)) { lblViewImage.Text = GetFileDictionary()[intImage]; } else { lblViewImage.Text = "Missing Image"; } } else { // Edit DropDownList ddlEditImage = ((DropDownList)e.Row.FindControl("ddlEditImage")); ddlEditImage.DataSource = GetFileDictionary(); ddlEditImage.DataBind(); if (GetFileDictionary().ContainsKey(intImage)) { ddlEditImage.SelectedValue = intImage.ToString(); } } } } catch (Exception exc) { //Module failed to load Exceptions.ProcessModuleLoadException(this, exc); } } How do I make sure that the Image value in the drop down list is passed to the update function?

Making a table in a scrolling div resizable?

- by Mason Jones

I've got a table in a div, with a vertical scrollbar on the div to allow the table to be longer than the div can hold. Works fine. But I'd like to allow the user to resize the div vertically if they want to be able to view more of the table. I've been playing with the jQueryUI resizable interaction, but it doesn't seem to quite do what I want; at least, not so far. I've tried making the wrapper div resizable, but the behavior's erratic. If I have the style "height:20em; overflow:auto;" on it, then I can resize the table horizontally, but not vertically. If I remove the overflow, then the table flows outside the div of course. If I remove the height, then the table is actually resizable, but it is initially drawn at full height. Anyone know of a way to specify an initial height, but allow it to be resized larger than that? If I make the table resizable rather than the div, then I can resize the table horizontally within the div but I can't increase the height of the displayed table. Which makes sense, of course, but I thought I'd mention it. Also, is there a way to make the resize "handle" the corner between the horizontal and vertical scrollbars? Right now it's a sort of invisible handle in the bottom-right of the table. Thanks for any thoughts.

How do I get a button to show on mouseover using jQuery?

z-index not working in IE8 with the sortable jQuery plugin

- by Ojtwist

I'm working with the jQuery Sortable plugin to drag and drop images from one box to another box. This works fine in ff,chrome and safari but it fails in IE8. It seems that when you start dragging that the image is send to the back. I've tried to solve this by adding the z-index option to the sortable plugin, i've tried appending it to a node higher in the hierarchy (body). It appears that setting a z-index on every other item in the page would fix this, haven't tried it yet and i'm not planning on doing this because this would mess up alot. So the user can drag an image from 1 gallery to the next gallery screenshot of how it should work: http://img69.imageshack.us/i/draganddrop.jpg/ Some html:  <a class="flickr_accordeon_header" id="flickr_second_header" href="javascript:;">__MSG__SEARCH_FOR_PHOTOS__</a> <div> <p class ="flickr_text" > __MSG__SEARCH_FOR_PHOTOS__</p> <form method="GET" action="javascript:;"> <p> <input type="text" value="__MSG__SEARCH__" id="flickr_key_input" class="flickr_changeColorNormal" /> <button class="s3d-button flickr_search" id="flickr_seach_button"> <span class="s3d-button-inner" >__MSG__SEARCH__</span> </button> <img src="/devwidgets/flickr/images/ajax-loader-gray.gif" alt="__MSG__LOADING_IMAGE__" id="flickr_loading_img" /> <a href="javascript:;" id="flickr_refresh_key_button"><img src="/dev/_images/recent_activity_icon.png" alt="refresh" title='refresh' /></a> </p> </form> <div id="flickr_input_error">__MSG__INPUT_ERROR__</div> <div id="flickr_input_same_error">__MSG__INPUT_SAME_ERROR__</div> **<div id="flickr_key_gallery" ><ul class="flickr_key_ul"><li></li></ul></div>** <div id="flickr_key_pagging" ></div> </div> </div>  <div id="flickr_sidebar" class="jcarousel-skin-tango"> <div id="flickr_side_paging"></div> **<ul> <li><img src="/devwidgets/flickr/images/drop-image.png" alt="__MSG__DROP_HERE__" class="flick_drop_here"></li> </ul>** </div> The images get rendered into the ul, so basically it's just an ul with li's with images javascript for sortable: horizontal: { helper: "clone", // Instead of dragging the real image a copy will be dragged connectWith: ["#flickr_sidebar ul"], // To be able to drag and drop an image to another image gallery they need to be connected cursor: 'pointer', //change the cursor when dragging opacity: 0.50, //Change the opacity while dragging appendTo: 'body', //When dropped the images need to be appended to the image gallery where they are dropped containment: 'body', //Make sure the user can't drag the images outside the widget revert: true, // if the user releases the image ouside the dropbox it'll return to it's original position zIndex: 9999 } I've tried it with setting the dragged image to absolute and the container on relative... doesn't work Anyone know how to solve this in IE8 ?

Modern/Metro Internet Explorer: What were they thinking???

- by Rick Strahl

As I installed Windows 8.1 last week I decided that I really should take a closer look at Internet Explorer in the Modern/Metro environment again. Right away I ran into two issues that are real head scratchers to me.Modern Split Windows don't resize Viewport but Zoom OutThis one falls in the "WTF, really?" department: It looks like Modern Internet Explorer's Modern doesn't resize the browser window as every other browser (including IE 11 on the desktop) does, but rather tries to adjust the zoom to the width of the browser. This means that if you use the Modern IE browser and you split the display between IE and another application, IE will be zoomed out, with text becoming much, much smaller, rather than resizing the browser viewport and adjusting the pixel width as you would when a browser window is typically resized.Here's what I'm talking about in a couple of pictures. First here's the full screen Internet Explorer version (this shot is resized down since it's full screen at 1080p, click to see the full image):This brings up the first issue which is: On the desktop who wants to browse a site full screen? Most sites aren't fully optimized for 1080p widescreen experience and frankly most content that wide just looks weird. Even in typical 10" resolutions of 1280 width it's weird to look at things this way. At least this issue can be worked around with @media queries and either constraining the view, or adding additional content to make use of the extra space. Still running a desktop browser full screen is not optimal on a desktop machine - ever.Regardless, this view, while oversized, is what I expect: Everything is rendered in the right ratios, with font-size and the responsive design styling properly respected.But now look what happens when you split the desktop windows and show half desktop and have modern IE (this screen shot is not resized but cropped - this is actual size content as you can see in the cropped Twitter window on the right half of the screen):What's happening here is that IE is zooming out of the content to make it fit into the smaller width, shrinking the content rather than resizing the viewport's pixel width. In effect it looks like the pixel width stays at 1080px and the viewport expands out height-wise in response resulting in some crazy long portrait view.There goes responsive design - out the window literally. If you've built your site using @media queries and fixed viewport sizes, Internet Explorer completely screws you in this split view. On my 1080p monitor, the site shown at a little under half width becomes completely unreadable as the fonts are too small and break up. As you go into split view and you resize the window handle the content of the browser gets smaller and smaller (and effectively longer and longer on the bottom) effectively throwing off any responsive layout to the point of un-readability even on a big display, let alone a small tablet screen.What could POSSIBLY be the benefit of this screwed up behavior? I checked around a bit trying different pages in this shrunk down view. Other than the Microsoft home page, every page I went to was nearly unreadable at a quarter width. The only page I found that worked 'normally' was the Microsoft home page which undoubtedly is optimized just for Internet Explorer specifically.Bottom Address Bar opaquely overlays ContentAnother problematic feature for me is the browser address bar on the bottom. Modern IE shows the status bar opaquely on the bottom, overlaying the content area of the Web Page - until you click on the page. Until you do though, the address bar overlays the bottom content solidly. And not just a little bit but by good sizable chunk.In the application from the screen shot above I have an application toolbar on the bottom and the IE Address bar completely hides that bottom toolbar when the page is first loaded, until the user clicks into the content at which point the address bar shrinks down to a fat border style bar with a … on it. Toolbars on the bottom are pretty common these days, especially for mobile optimized applications, so I'd say this is a common use case. But even if you don't have toolbars on the bottom maybe there's other fixed content on the bottom of the page that is vital to display. While other browsers often also show address bars and then later hide them, these other browsers tend to resize the viewport when the address bar status changes, so the content can respond to the size change. Not so with Modern IE. The address bar overlays content and stays visible until content is clicked. No resize notification or viewport height change is sent to the browser.So basically Internet Explorer is telling me: "Our toolbar is more important than your content!" - AND gives me no chance to re-act to that behavior. The result on this page/application is that the user sees no actionable operations until he or she clicks into the content area, which is terrible from a UI perspective as the user has no idea what options are available on initial load.It's doubly confounding in that IE is running in full screen mode and has an the entire height of the screen at its disposal - there's plenty of real estate available to not require this sort of hiding of content in the first place. Heck, even Windows Phone with its more constrained size doesn't hide content - in fact the address bar on Windows Phone 8 is always visible.What were they thinking?Every time I use anything in the Modern Metro interface in Windows 8/8.1 I get angry. I can pretty much ignore Metro/Modern for my everyday usage, but unfortunately with Internet Explorer in the modern shell I have to live with, because there will be users using it to access my sites. I think it's inexcusable by Microsoft to build such a crappy shell around the browser that impacts the actual usability of Web content.

trouble running smooth animation in thread only when using key listener

- by heysuse renard

first time using a forum for coding help so sorry if i post this all wrong. i have more than a few classes i don't think screenManger or core holds the problem but i included them just incase. i got most of this code working through a set of tutorials. but a certain point started trying to do more on my own. i want to play the animation only when i'm moving my sprite. in my KeyTest class i am using threads to run the animation it used to work (poorly) but now not at all pluss it really gunks up my computer. i think it's because of the thread. im new to threads so i'm not to sure if i should even be using one in this situation or if its dangerous for my computer. the animation worked smoothly when i had the sprite bouce around the screen forever. the animation loop played with out stopping. i think the main problem is between the animationThread, Sprite, and keyTest classes, but itcould be more indepth. if someone could point me in the right direction for making the animation run smoothly when i push down a key and stop runing when i let off it would be greatly apriciated. i already looked at this Java a moving animation (sprite) obviously we were doing the same tutorial. but i feel my problem is slightly different. p.s. sorry for the typos. import java.awt.*;

How do I scale a UIButton's imageView?

- by vcLwei

Hey guys! I create a UIButton instance(named "button") with a image use [UIButton setImage:forState:] function, the button.frame is larger than the image's size. Now I want to scale this button's image smaller. I had tried to change button.imageView.frame, button.imageView.bounds and button.imageView.contentMode, but all seem ineffective. Hopefully someone can help me how to scale a UIButton's imageView.Thanks! my create UIButton instance code: UIButton *button = [[UIButton alloc] init]; [button setImage:image forState:UIControlStateNormal]; my try to scale the image code: button.imageView.contentMode = UIViewContentModeScaleAspectFit; button.imageView.bounds = CGRectMake(0, 0, 70, 70); and: button.imageView.contentMode = UIViewContentModeScaleAspectFit; button.imageView.frame = CGRectMake(0, 0, 70, 70);
