  • C# - Erase all property values from a class?

    - by John M
    In a C# Winforms (3.5) application I have added a class that contains many properties (get/set) used to stored values from a 12 form long process. After form 12 I would like wipe out all the property values in the storing class so that the next user won't accidentally record values when starting the process at form 1. Is it possible to erase/destroy/dispose of all property values in a class? My class looks like this: private static int battery; public int Battery { get { return storeInspectionValues.battery; } set { storeInspectionValues.battery = value; } }

  • Extreamely fast way to clone the values of an array into a second array?

    - by George
    I am currently working on an application that is responsible for calculating random permutations of a multidemensional array. Currently the bulk of the time in the application is spent copying the array in each iteration (1 million iterations total). On my current system, the entire process takes 50 seconds to complete, 39 of those seconds spent cloning the array. My array cloning routine is the following: public static int[][] CopyArray(this int[][] source) { int[][] destination = new int[source.Length][]; // For each Row for (int y = 0; y < source.Length; y++) { // Initialize Array destination[y] = new int[source[y].Length]; // For each Column for (int x = 0; x < destination[y].Length; x++) { destination[y][x] = source[y][x]; } } return destination; } Is there any way, safe or unsafe, to achieve the same effect as above, much faster?

  • Debug.writeline locks

    - by Carra
    My program frequently stops with a deadlock. When I do a break-all and look at the threads I see that three threads are stuck in our logging function: public class Logging { public static void WriteClientLog(LogLevel logLevel, string message) { #if DEBUG System.Diagnostics.Debug.WriteLine(String.Format("{0} {1}", DateTime.Now.ToString("HH:mm:ss"), message)); //LOCK #endif //...Log4net logging } } If I let the program continue the threads are still stuck on that line. I can't see where this can lock. The debug class, string class & datetime class seem to be thread safe. The error goes away when I remove the "#if DEBUG System... #endif" code but I'm curious why this behavior happens. Thread one: public void CleanCache() { Logging.WriteClientLog(LogLevel.Debug, "Start clean cache.");//Stuck } Thread two: private void AliveThread() { Logging.WriteClientLog(LogLevel.Debug, "Check connection");//Stuck }

  • Why did I get a 400 Bad Request when getting a page with PHP Curl?

    - by user307272
    Hi, I was trying to access a page using curl. I could access it perfectly using the browser and using "static" strings as the URL, like: $url = "http://www.example.com/?q=1234" But when I tried to access the page using a variable in the URL string like: $url = "http://www.example.com/?q=$param" I got a 400 error code. I checked out on the web and found some comments here in this stackoverflow thread: Then, just for curiosity I did the following: $url = "http://www.example.com/?q=" . trim($param); and it worked! And no, $param did NOT contain any spaces. To me, it seems that it can be some encoding error, but I really can't find an explanation for it. Does anyone here in stackoverflow know what it can possibly be? Thanks in advance :)

  • Why is the Dependency Property not returning its value?

    - by B-Rad
    I have a MyUserControl with the following Xaml: <TextBox Text="{Binding InputValueProperty}" /> In the MyUserControl.xaml.cs I have: public string InputValue { get { return (string)GetValue(InputValueProperty); } set { SetValue(InputValueProperty, value); } } public static readonly DependencyProperty InputValueProperty = DependencyProperty.Register("InputValueProperty", typeof(string), typeof(MyUserControl)); In my MainWindow.xaml I create a user control: <local:MyUserControl InputValue="My Input" /> Later on in my MainWindow.xaml.cs I am trying to access this string. All instances of MyUserControl are contained in a List and I access them with a foreach. string temp = userControl.InputValue; This is always null. In my MainWindow.xaml I can see the "My Input" in the text box of the user control but I can't ever seem to get it out of there.

  • Why does GetExportedValues<T>() no longer work after using the .net 4 final version of MEF?

    - by BigJason
    I have been developing a managed extensibility framework application for the last several months using the community preview. I have been using the GetExportedValues() method and the PartCreationPolicy(CreationPolicy.NonShared) to fake a class factory (since only the silverlight version supports a factory). This was working great until I upgraded the project to use .net 4.0. There is no error, it just doesn't work. So why did this code stop working? The code follows: The factory method: public static IEnumerable<DataActionBase> GetActionsFromDirectory(string PluginsFolder) { IEnumerable<DataActionBase> result = null; var catalog = new DirectoryCatalog(PluginsFolder); var container = new CompositionContainer(catalog: catalog); result = container.GetExportedValues<DataActionBase>(); return result; } Example Export Class: [Export(typeof(DataActionBase))] [PartCreationPolicy(CreationPolicy.NonShared)] public class AnAction : DataActionBase { .... }

  • Virtual PC (XPMode) - How to access Webserver on guest from host

    - by sannoble
    I have Windows XP running inside Windows 7 via Virtual PC (XPMode) and installed Zend Server CE on the virtual XP guest. The webserver is running and can be accessed on the guest, but I cannot access the webserver from the Win7 host. I configured a static IP address and subnet of 255.255.255.0 on the guest and can ping this IP from the guest but not from the host. The other way it works fine, i.e. I can ping the host from the guest. I can also access the internet from the virtual XP guest. I tried different Network Options in the VirtualPC settings, but nothing helps. Googling the topic I couldn't find anything helpful yet. Any idea, what I could try to access the webserver on the virtual XP guest from the Win7 host?

    i need my code to replace the ? with the letter guessed. The ? needs to be replaced with a for only those to spots. The word in array is parameter. public static void replace(String[] wordOne, String blanks, char guess) { int i; blanks = wordOne[0]; for (i = 0; i < wordOne.length; i++) { for (int j = 0; j < wordOne[0].length(); j++) { blanks = blanks.replace(blanks.charAt(j), '?'); if (wordOne[0].charAt(i) == guess) { blanks = blanks.replace(blanks.charAt(i), guess); } } } System.out.println(blanks); } }

  • How to continue copying on error with copyDirectory from FileUtils (Apache Commons IO 2.4)

    - by Exocom
    I am trying to copy files from one folder to another using the FileUtils method "static void copyDirectory(File srcDir, File destDir)" from apache commons io (2.4) with the following code: String srcDir = "/sourceDirectory/examples/"; String destDir = "/tmp/examples/"; try{ FileUtils.copyDirectory(new File(srcDir), new File(destDir)); } catch (IOException e){ e.printStackTrace(); } The file structure looks like the following: examples/ (read access) examples/.subdirectory (NO access) examples/file1.txt (read access) examples/file2.txt (read access) examples/subdirectory2/file1.txt (read access) examples/subdirectory2/file2.txt (NO access) The problem is, that in srcDir there are a few files and one subdirectory I don't have access to. FileUtils.copyDirectory throws an "java.io.FileNotFoundException: .subdirectory (Permission denied)" and aborts. Is it possible to ignore those files I don't have permission to and just copy all the other files I can read?

    - by bartq
    I want to open from c# an application (standalone flashplayer) and set it position to (0,0) on the screen. How can I do this?

  • Could someone explain __declspec(naked) please?

    - by Scott
    I'm looking into porting a script engine written for Windows to Linux; it's for Winamp's visualization platform AVS. I'm not sure if it's even possible at the moment. From what I can tell the code is taking the addresses of the C functions nseel_asm_atan and nseel_asm_atan_end and storing them inside a table that it can reference during code execution. I've looked at MS's documentation, but I'm unsure what __declspec(naked) really does. What is prolog and epilog code mentioned in the documentation? Is that related to Windows calling conventions? Is this portable? Know of any Linux-based examples using similar techniques? static double (*__atan)(double) = &atan; __declspec ( naked ) void nseel_asm_atan(void) { FUNC1_ENTER *__nextBlock = __atan(*parm_a); FUNC_LEAVE } __declspec ( naked ) void nseel_asm_atan_end(void) {}

  • Data structure name: combination array/linked list

    - by me_and
    I have come up with a data structure that combines some of the advantages of linked lists with some of the advantages of fixed-size arrays. It seems very obvious to me, and so I'd expect someone to have thought of it and named it already. Does anyone know what this is called: Take a small fixed-size array. If the number of elements you want to put in your array is greater than the size of the array, add a new array and whatever pointers you like between the old and the new. Thus you have: Static array ————————————————————————— |1|2|3|4|5|6|7|8|9|a|b|c| ————————————————————————— Linked list ———— ———— ———— ———— ———— |1|*->|2|*->|3|*->|4|*->|5|*->NULL ———— ———— ———— ———— ———— My thing: ———————————— ———————————— |1|2|3|4|5|*->|6|7|8|9|a|*->NULL ———————————— ————————————

  • Address of array vs. address of array[0] - C language

    - by user324994
    My question is why does the address of an array differ from the address of its first position? I'm trying to write my own malloc, but to start out I'm just allocating a chunk of memory and playing around with the addresses. My code looks roughly like this: #define BUFF_SIZE 1024 static char *mallocbuff; int main(){ mallocbuff = malloc(BUFF_SIZE); printf("The address of mallocbuff is %d\n", &mallocbuff); printf("The address of mallocbuff[0] is %d\n", &mallocbuff[0]); } &mallocbuff is the same address every time I run it. &mallocbuff[0] is some random address every time. I was expecting the addresses to match each other. Can anyone explain why this isn't the case?

  • Flash: How to get a list to be processed synchronous instead of asynchronous?

    - by Quandary
    Question: In Flash I have the below function. Now the problem is SaveFurniture, SavePolygons and SaveComments all save to the same XML file. Now SaveFurniture sends JSON encoded data to a ashx handler, which saves it in the xml on the server. The problem is, because flash sends the data asynchronous, the polygons get sent to the polygonsave ashx handler, but before saving of the furniture has completed, thus access error, write process already in progress... // cSaveData.SaveData(); public static function SaveData():void { trace("cSaveData.SaveData"); //NotifyASPXofNewScale(cGlobals.nPlanScale); SaveFurniture(); SavePolygons(); SaveComments(); } What's the best way to process this list, ONE AFTER ANOTHER ? Making a callback in all of them does make the program flow structure very confusing...

  • Converting java language output to Joomla language output

    - by jax
    in java if I run : Locale.getDefault().toString() I get zh_tw I am sending this to a joomla site and setting the language like this: $lang = &JFactory::getLanguage(); $lang->setLanguage( $_GET['lang'] ); $lang->load(); however the site requires the following format zh-TW It appears that if it is not in that exact format the language will not change. Is there a function somewhere in java or php that will convert the format for me? I realise that I could write the method myself like this: public static String convertLanguageToJoomlaFormat(String lang) { String[] parts = lang.split("_"); if(parts.length ==2) return parts[0]+"-"+parts[1].toUpperCase(); return lang; } but am unsure if there are any cases where the format changes for particular languages.

  • Animate a e.Graphics.DrawLine with arrowhead

    - by Fer
    I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it to delete it from the screen, and its background is really transparent (no color.transparent) so i can't paint the background to "clear" the previous line. I have it static already (drawn from origin to end) but i can't animate it. I tried to add a timer in the user control but I fail to get a correct algorithm to calculate the intermediate ends of the line while it is growing. Any help would be appreciated. Thanks

  • View is moved 3 pixels

    - by Jakub
    Hello, In my app I move the table view (in order to make the text fields visible when the keyboard appears). The view is looks following: This is the code I use for resizing the view and moving it up: static const NSUInteger navBarHeight = 44; CGRect appFrame = [[UIScreen mainScreen] applicationFrame]; tableView.frame = CGRectMake(0, navBarHeight, appFrame.size.width, appFrame.size.height-navBarHeight-216); //216 for the keyboard NSIndexPath *indPath = [self getIndexPathForTextField:textField]; //get the field the view should scroll to [tableView scrollToRowAtIndexPath:indPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES]; The problem is that when the view is moved up it also moves 3 pixels into right direction (it is hard to see the difference in the screenshot, but it is visible when the animation is on and I measured the difference with PixelStick tool). Here it is how it looks after the move: My analysis shows that scrolling the table does not influence the move to the right. Any ideas what is wrong in the code above that makes the view move to the right?

  • C# .NET 2.0 components

    - by Ervin
    How can I check what objects, tools, variables, anything... are used from .NET 2.0 in a C# application. How can I get a C# application run without .NET 2.0 ? UPDATE: sorry, I didn't clarify enought. Here's my situation: I have developed a pretty simple application in C#: embeded browser which displayes static webpages with an option of searching inside of these html pages. I'm using simple textbox, buttons components for this. The application will be distribuited for people wich have very old PCs, even with windows 95. I would like the app to be runable on it, or at least on win 98, without telling the people to install .NET 2.0, as the users don;t really have PC usage skills :) .

  • Run .exe packaged in .jar

    - by user1471327
    I am trying to merge 2 programs I have made to one .jar file. One program is a .jar written in java and the second one is an .exe written in c++. I put both files to the new .jar, wrote this code but it didn't work. When this code was exported to .jar and executed neither of 2 files ran and I got error "no main manifest attribute, in merged.jar" in cmd. Though it worked perfectly when run in eclipse. public class main { public static void main(String[] args) { try { Runtime.getRuntime().exec("cmd /c project1.jar"); Runtime.getRuntime().exec("cmd /c project2.exe"); } catch(Exception exce) { /*handle exception*/ } } } Any idea how to fix this or is there another way to do it? I am new to java, so can't think of anything good. Maybe it would be possible to drop these files to a temporary location in windows and delete them after they're executed?
