  • What does error 0xC02020C4 mean in SSIS?

    I get this error with this description. Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on component "OLE DB Source" (1) returned error code 0xC02020C4. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.

  • Generating a KML heatmap from given data set of [lat, lon, density]

    - by Will Croft
    I am looking to build a static KML (Google Earth markup) file which displays a heatmap-style rendering of a few given data sets in the form of [lat, lon, density] tuples. A very straightforward data set I have is for population density. My requirements are: must be able to feed in data for a given lat, lon must be able to specific the given density of the data at that lat, lon must export to KML The requirements are language agnostic for this project as I will be generating these files offline in order to build the KML used elsewhere. I have looked at a few projects, most notably heatmap.py, which is a port of gheat in Python with KML export. I have hit a brick wall in the sense that the projects I have found to date all rely on building the heatmap from the density of [lat, lon] points fed into the algorithm. If I am missing an obvious way to adapt my data set to feed in just the [lat, lon] tuples but adjusting how I feed them using the density values I have, I would love to know!

  • C# - Kinetic scrolling with ListBox or ListView?

    - by fonix232
    I am doing a simple application for touch screen devices, and I would like to implement today's fashion: kinetic scrolling. Is it possible to do, and if yes, how? PS: Kinetic scrolling: A scrolling mechanism where you don't use a scrollbar to scroll the content, but you touch the list itself, and pull and push it. The "physics engine" then counts out the speed, and stops based on the given settings.

  • C++ Profiling: KiFastSystemCallRet

    - by John
    I searched for this after seeing it's the top rated item when profiling using Very Sleepy, and it seems everyone gets the answer "it's a system function, ignore it". But Sleepy's hint for the function says: Hint: KiFastSystemCallRet often means the thread was waiting for something else to finish. Possible causes might be disk I/O, waiting for an event, or maybe just calling Sleep(). Now, my app is absolutely thrashing the CPU and so it's a bit weird 33% of the time is spent waiting for something to happen. Do I really just ignore it? EDIT: apparently, 77% of the calls to this come from QueryOglResource (?) which is in module nvd3dnum. I think that might be nvidia Direct3D stuff, i.e rendering.

  • Overlay WriteableBitmap with color

    - by rajenk
    I'm trying to overlay a WriteableBitmap with a certain color in Silverlight. I have a black and white base image, which I'm using to create smaller WriteableBitmap images for a new composite image and I want to overlay either the black or white part of the source image cut-out with a certain color before adding it to the composite image. What I'm doing now is: var cutOut = new WriteableBitmap(8, 14); /* cut out the image here */ cutOut.Render(sourceImage, transform); // sourceImage is the base image cutOutImage.Source = cutOut; // cutOutImage is an Image element in XAML compositeImage.Render(cutOutImage, transform2); // compositeImage is the final WriteableBitmap that is shown on screen I tried the methods on http://blogs.silverarcade.com/silverlight-games-101/15/silverlight-blitting-and-blending-with-silverlights-writeablebitmap/ and using the extension methods from hxxp://writeablebitmapex.codeplex.com/, but I cannot seem to get a color overlay on the cutOut image before rendering it to the compositeImage. Does anyone know of a good method to do this? Thanks in advance.

  • Running IE6, IE7, and IE8 on the same machine

    - by Alessandro Vernet
    Like everyone else ;), I need to test my code on IE6 and IE7. Now IE8 has some great tools for developer, which I'd like to use. I'd also like to start testing my code with IE8, as it will soon be released. The question is: how to run IE6, IE7, and IE8 on the same machine. So far with IE6 and IE7 I've been using Multiple IE. But people have reported (see comments on the page linked in the previous sentence) issue with IE6 after installing IE8. Those errors are related to focus in form fields. Running IE7 wouldn't matter so much as IE8 can use the IE7 rendering engine, but we still need IE6. Any recommendation on how to IE6, IE7, and IE8 on the same machine?

  • Shared Cookies between WebView and HTTPClient?

    - by Arpit
    An Android app I am building requires web authentication for users to make data calls. In Adobe AIR and later the iPhone, we did this by rendering a login page in a webview-equivalent page and setting a cookie when the user signs in. Subsequent data calls use the same Cookie Jar and so are seen as authenticated. In the Android version, I authenticate the user using a WebView and then once thats done, I make a data call using DefaultHttpClient, however I cant seem to load the data on the second call. Is there some cookie gotcha I am missing? I imagine the HTTPClient and WebView would share the same Cookie space. Am I wrong?

  • how to replace latex macros with their definitions (using latex)

    - by RamyenHead
    How can I replace all occurrence of user defined latex macros with their definitions? For example, given this file old.tex \newcommand{\blah}[2]{#1 \to #2} ... foo \blah{egg}{spam} bar ... how to generate the file below in an automatic way new.tex ... foo egg \to spam bar ... Instead of reimplementing latex macro logic with perl, can I use latex or tex engine itself to do this?

  • How to use Bouncy Castle lightweight API with AES and PBE

    - by Adrian
    I have a block of ciphertext that was created using the JCE algorithim "PBEWithSHA256And256BitAES-CBC-BC". The provider is BouncyCastle. What I'd like to do it decrypt this ciphertext using the BouncyCastle lightweight API. I don't want to use JCE because that requires installing the Unlimited Strength Jurisdiction Policy Files. Documentation seems to be thin on the ground when it comes to using BC with PBE and AES. Here's what I have so far. The decryption code runs without exception but returns rubbish. The encryption code, String password = "qwerty"; String plainText = "hello world"; byte[] salt = generateSalt(); byte[] cipherText = encrypt(plainText, password.toCharArray(), salt); private static byte[] generateSalt() throws NoSuchAlgorithmException { byte salt[] = new byte[8]; SecureRandom saltGen = SecureRandom.getInstance("SHA1PRNG"); saltGen.nextBytes(salt); return salt; } private static byte[] encrypt(String plainText, char[] password, byte[] salt) throws NoSuchAlgorithmException, InvalidKeySpecException, NoSuchPaddingException, InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException { Security.addProvider(new BouncyCastleProvider()); PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, 20); PBEKeySpec pbeKeySpec = new PBEKeySpec(password); SecretKeyFactory keyFac = SecretKeyFactory.getInstance("PBEWithSHA256And256BitAES-CBC-BC"); SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec); Cipher encryptionCipher = Cipher.getInstance("PBEWithSHA256And256BitAES-CBC-BC"); encryptionCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec); return encryptionCipher.doFinal(plainText.getBytes()); } The decryption code, byte[] decryptedText = decrypt(cipherText, password.getBytes(), salt); private static byte[] decrypt(byte[] cipherText, byte[] password, byte[] salt) throws DataLengthException, IllegalStateException, InvalidCipherTextException, InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException { BlockCipher engine = new AESEngine(); CBCBlockCipher cipher = new CBCBlockCipher(engine); PKCS5S1ParametersGenerator keyGenerator = new PKCS5S1ParametersGenerator(new SHA256Digest()); keyGenerator.init(password, salt, 20); CipherParameters keyParams = keyGenerator.generateDerivedParameters(256); cipher.init(false, keyParams); byte[] decryptedBytes = new byte[cipherText.length]; int numBytesCopied = cipher.processBlock(cipherText, 0, decryptedBytes, 0); return decryptedBytes; }

  • Looping to provide multiple lines in linechart (django-googlecharts)

    - by mighty_bombero
    Hi, I'm trying to generate some charts using django-googlecharts. This works fine for rather static data but in one case I would like to render a different number of lines, based on a variable. I tried this: {% chart %} {% for line in line_data %} {% chart-data line %} {% endfor %} {% chart-size "390x200" %} {% chart-type "line" %} {% chart-labels days %} {% endchart %} Line data is a list containing lists. The template code fails with "Caught an exception while rendering: max() arg is an empty sequence". I guess the problem is that I try to loop over templatetags. What approach could be used here? Or am I completely missing something? Is this doable using inclusion tags? Thanks for your help.

  • Why aren't we programming on the GPU???

    - by Chris
    So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

  • underline text in UIlabel

    - by semix
    How to underline a text that could be multiple lines of string? I find some people suggest UIWebView, but it is obviously too heave a class for just text rendering. My thoughts was to figure out the start point and length of each string in each line. And draw a line under it accordingly. I meet problems at how to figure out the length and start point forthe string. Can anybody help me on this? I try to use UILable::textRectForBounds, this should be the drawing bounding rect for the text right? Then I have to work on the aligment ? How can I get the start point of each line when it is center-justified and right justfied? I am new here, so thank in advance.

  • Accessing original WordPress blog's DB from sub-blogs in network mode

    - by aendrew
    I'm helping with a university radio station website that runs WordPress and was recently switched over to Network (Multi-site/multi-user) mode by myself. The setup is as such: The parent site (www.stationID.com) runs a bunch of custom-built plugins to construct things like the show schedule calendar, the "Now Playing" widget, podcast list, et cetera. The new network websites ("wiki.stationID.com", "buddypress.stationID.com" for instance) run the same template as the parent site, but it stops after rendering the first section because the widgets from point 1 grab data from the main site's database that is not available to sub-blogs. My question is: how do I get data from the main site's tables on the sub-domain sub-blogs? A related question is: how do I set the $wpdb->prefix to be the same as the parent site on the child websites without it negatively effecting how the child website pulls data from its own database? Any help would be awesome, thanks!

  • MVP on Asp.Net WebForms

    - by Nicolas Irisarri
    I'm not clear about this.... When having a gridview on the View, is the controller who has to set up the Data source, columns, etc? or I just have to expose the DataBinding stuff, fire it from the controller and let the html/codebehind on the view handle all the rendering and wiring up? To be more precise: on the view should I have private GridView _gv public _IList<Poco> Source { get {_gv.DataSource;} set {_gv.DataSource = value; _gv.DataBind();} } Or should it be (from http://stackoverflow.com/questions/153222/mvp-pattern-passive-view-and-exposing-complex-types-through-iview-asp-net-web) private GridView _datasource; public DataSource { get { return _datasource; } set { _datasource = value; _datasource.DataBind(); } } Maybe I'm having it all wrong .... Where can I find an example that is not a "Hello world" example on MVP for ASP.Net???

  • CSS regression tool?

    - by ronaldwidha
    I'm looking for a visual regression testing tool for CSS refactoring and see whether or not there are any unintended cascading behavior in a website. Ideally, the tool that can crawl a website (even locally) and grab snapshots of each page and store it in a single repository. When run for the second time, it will show the pages that are visually different since the last time it was run. Even better: if it can show the overlapper XOR view of the 2 version of the page. compare rendering results of different browsers (almost like an automated Microsoft Expression Web compare feature). Thanks

  • JavaScript tree / treegrid libraries

    - by desau
    I'm looking for a good JavaScript tree / treegrid package. Now -- before you answer: It needs to be able to perform well with lots of nodes. Perhaps 1,000 sibling nodes. It needs to be able to draw to a usable state within 2 or 3 seconds with 1,000 nodes. It doesn't necessarily need to draw all 1,000 nodes at once -- if it supports some sort of "smart rendering" or fake scrolling. Beyond that, column resizing, drag and drop, inline editing would all be nice, although I could probably add that functionality myself. I've already tried dojo's tree and yahoo's YUI treeview. Both are too slow.

  • glPushName + glPopName stack overflow and underflow

    Can anybody please explain me how to use glPushName and glPopName. I like to use them instead of glLoadName, but I laways get GL_STACK_OVERFLOW and GL_STACK_UNDERFLOW errors. (First, under then overflow). Example code would help me too. Thanks for any advice. Note #1: My Rendering/selection_rednering code consists of multiple glBegin(...)/glEnd() blocks, if this is any problem plus various Rotations and Transformations. Note #2: I know that GL selection / picking is deprecated, but I have to implement it within a Application which was developed a with OpenGL2.1 a while ago.
