  • What is unit testing?

    - by Alon
    What is unit testing and unit testing libraries like xUnit? I understood it's testing specific code, so what's the difference between this and just opening a new project and test this specific code?

  • VB.NET Function Return

    - by waves
    In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?

  • Can a power loss break an hard disk?

    - by dag729
    Today I was working when all of a sudden a power loss (in the entire house) occurs. I tried to reboot the machine but it states that there's an "Ebios error"; tried with an Ubuntu 9.04 live cd and while booting it states that there are various I/O errors on the first partition (the one with the boot sector). Now I managed to backup all of my data (using the live cd aforementioned) but I don't know if it'll worth the hassle of a reinstallation (and if it could do something useful) or if the only thing to do is to drop the hard disk as far as possible... Thanks in advance.

  • Decrypting a TrueCrypt drive pulled from another machine

    - by Blakeg08
    I work in a corporate environment and we are now required to encrypt laptops. I have already encrypted about 5 or 6 out of 40. I still have a few questions before we go all out with TrueCrypt. Can I decrypt a hard drive by plugging it into my desktop using a data transfer kit? I tried this and the hard drive showed up asking me to format before using the volume. If I have the TRD from each laptop backed up do I still need to backup the volume headers? What else do I need to back up? Thanks.

  • Equivalent of System.Windows.Forms.Cursor in Web Application(Asp.Net)

    - by Vishwa
    Hi I have a code in windows application now i am trying to implement in web Application but it is showimg that it ths no cursor class (System.Windows.Forms.Cursor )so..wat is the equivalent in web application. Here is my code private void btnGo_Click(System.Object sender, System.EventArgs e) { this.Cursor = Cursors.WaitCursor; Application.DoEvents(); // Load the images. Bitmap bm1 = (Bitmap) (Image.FromFile(txtFile1.Text)); Bitmap bm2 = (Bitmap) (Image.FromFile(txtFile2.Text)); // Make a difference image. int wid = Math.Min(bm1.Width, bm2.Width); int hgt = Math.Min(bm1.Height, bm2.Height); Bitmap bm3 = new Bitmap(wid, hgt); // Create the difference image. bool are_identical = true; int r1; int g1; int b1; int r2; int g2; int b2; int r3; int g3; int b3; Color eq_color = Color.White; Color ne_color = Color.Transparent; for (int x = 0; x <= wid - 1; x++) { for (int y = 0; y <= hgt - 1; y++) { if (bm1.GetPixel(x, y).Equals(bm2.GetPixel(x, y))) { bm3.SetPixel(x, y, eq_color); } else { bm1.SetPixel(x, y, ne_color); are_identical = false; } } } // Display the result. picResult.Image = bm1; Bitmap Logo = new Bitmap(picResult.Image); Logo.MakeTransparent(Logo.GetPixel(1, 1)); picResult.Image = (Image)Logo; this.Cursor = Cursors.Default; if ((bm1.Width != bm2.Width) || (bm1.Height != bm2.Height)) { are_identical = false; } if (are_identical) { MessageBox.Show("The images are identical"); } else { MessageBox.Show("The images are different"); } //bm1.Dispose() // bm2.Dispose() }

  • Attaching a function to the parent window from an iframe and getting proper scope

    - by Ronald
    I working on adding file uploading to my web application. I'm using an iframe to post my upload. When my php script processes the upload it writes some JavaScript to the iframe. This JavaScript is attempting to attach a function to the parent, this works, but when this function actually gets called it doesn't have the correct scope. Here is the code I'm attaching to the parent window: parent.window.showPreview = function(coords) { if (parseInt(coords.w) > 0) { var rx = 200 / coords.w; var ry = 250 / coords.h; $('#preview').css({ width: Math.round(rx * 400) + 'px', height: Math.round(ry * 533) + 'px', marginLeft: '-' + Math.round(rx * coords.x) + 'px', marginTop: '-' + Math.round(ry * coords.y) + 'px' }); } } When this function gets executed I get an error that says $ is not defined. I've tried adding changing the JQuery call to parent.$('#preview').css..., but then it says that parent is undefined. Any ideas?

  • c++ std::ostringstream vs std::string::append

    - by NickSoft
    In all examples that use some kind of buffering I see they use stream instead of string. How is std::ostringstream and << operator different than using string.append. Which one is faster and which one uses less resourses (memory). One difference I know is that you can output different types into output stream (like integer) rather than the limited types that string::append accepts. Here is an example: std::ostringstream os; os << "Content-Type: " << contentType << ";charset=" << charset << "\r\n"; std::string header = os.str(); vs std::string header("Content-Type: "); header.append(contentType); header.append(";charset="); header.append(charset); header.append("\r\n"); Obviously using stream is shorter, but I think append returns reference to the string so it can be written like this: std::string header("Content-Type: "); header.append(contentType) .append(";charset=") .append(charset) .append("\r\n"); And with output stream you can do: std::string content; ... os << "Content-Length: " << content.length() << "\r\n"; But what about memory usage and speed? Especially when used in a big loop. Update: To be more clear the question is: Which one should I use and why? Is there situations when one is preferred or the other? For performance and memory ... well I think benchmark is the only way since every implementation could be different. Update 2: Well I don't get clear idea what should I use from the answers which means that any of them will do the job, plus vector. Cubbi did nice benchmark with the addition of Dietmar Kühl that the biggest difference is construction of those objects. If you are looking for an answer you should check that too. I'll wait a bit more for other answers (look previous update) and if I don't get one I think I'll accept Tolga's answer because his suggestion to use vector is already done before which means vector should be less resource hungry.

  • Is it possible to use SQL XML to insert, and get output from each record?

    - by nbolton
    I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible? I guess it doesn't matter if the result is/isn't XML, but the input certainly has to be.

  • ActionScript 3 Context Menu Per Sprite?

    - by TheDarkIn1978
    is it not possible to have different context menus for different sprites on the stage? i've tried adding a custom context menu to a sprite but it's applied to the entire stage: mySprite.contextMenu = myMenu; then after reading the documentation where it states: You can attach a ContextMenu object to a specific button, movie clip, or text field object, or to an entire movie level. You use the menu property of the Button, MovieClip, or TextField class to do this. ok, so i though i had to write it like: mySprite.menu.contextMenu = myMenu; only to be greeted with a nice migration issue stating that menu is legacy code and to use contextMenu instead. ??? um, thanks for the headsup, documentation. this process would be entirely much more easier if i could extend the ContextMenu, but for some reason it's marked as "final" and can't be extended... i'm sure adobe's reasons for finalizing the context menu class are as good as their reasons for including misleading documentation. thoughts?

  • C++: ptr->hello(); /* VERSUS */ (*ptr).hello();

    - by Joey
    i was learning about c++ pointers... so the "-" operator seemed strange to me... instead of ptr-hello(); one could write (*ptr).hello(); because it also seems to work, so i thought the former is just a more convenient way is that the case or is there any difference?

  • How to build a tree from a list of items and their children recursively in php?

    - by k1lljoy
    I have a list of items stored in the DB, simplified schema is like this: id, parent, name I need to generate a tree structure (in a form of a multi-dimensional array) that can be infinite levels deep. Top level items would have parent = 0. Next level down would have parent equal to the the id of the parent item, fairly straight forward. What would be the best way to do this, while consuming as little resources as possible?

  • YAHOO.util.Connect.asyncRequest does not work in Safari

    - by 24x7Programmer
    When I request a webpage using YAHOO.util.Connect.asyncRequest in Safari I always get Communication Failure message in callback's failure properties statusText. The same method works in IE. What could be wrong here? Here is the code. When the code is executed I always get two alerts: "Three" and "communications failure undefined" (corresponding to the second alert in the failure part below.) Also when I attach the debugger and put break point in the SAProvision.aspx's page load event, the break point is not hit. So it is sure that in safari the page is not being called. While the same is called when executed from IE. function ProvisionBlade() { var path = "http://localhost/SC/Dashboard/SAProvision.aspx" YAHOO.util.Connect.asyncRequest("POST", path, callbacks1, null); } var callbacks1 = { success: function(o) { var check = "test"; alert(o.responseText); }, failure: function(o) { alert("Three"); alert(o.statusText + ' ' + o.responseText); } }

  • How does a parser LL(*) works?

    - by freezer878
    Hi, I cannot find any complete description about LL() parser, such as ANTLR, on Internet. I'm wondering what is the difference between an LL(k) parser and an LL() one and why they can't support left-recusrive grammars despite their flexibility. Thanks in advance. Fabio.

  • Passing around a SqlConnection

    - by Chris
    I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?
