  • How to measure how long is a function running?

    - by rhose87
    I want to see how long a function is running. So I added a timer object on my form and I came out with this code: private int counter = 0; //inside button click I have: timer = new Timer(); timer.Tick += new EventHandler(timer_Tick); timer.Start(); Result result = new Result(); result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia); timer.Stop(); and: private void timer_Tick(object sender, EventArgs e) { counter++; btnTabuSearch.Text = counter.ToString(); } But this is not counting anything. Any ideas?

  • What the best way to convert from String to HashMap?

    - by eugenn
    I would like to serialize a Java HashMap to string representation. The HashMap will contains only primitive values like string and integer. After that this string will be stored to db. How to restore back the HashMap? Is it make sense to use BeanUtils and interface Converter or use JSON? For example: List list = new ArrayList(); list.add(new Long(1)); list.add(new Long(2)); list.add(new Long(4)); Map map = new HashMap(); map.put("cityId", new Integer(1)); map.put("name", "test"); map.put("float", new Float(-3.2)); map.put("ids", list); map.toString() -> {float=-3.2,ids=[1, 2, 4],name=test,cityId=1} map.toJSON -> {"float":-3.2,"ids":[1,2,4],"name":"test","cityId":1}

  • asp.net: moving from session variables to cookies

    - by P a u l
    My forms are losing session variables on shared hosting very quickly (webhost4life), and I think I want to replace them with cookies. Does the following look reasonable for tracking an ID from form to form: if(Request.Cookies["currentForm"] == null) return; projectID = new Guid(Request.Cookies["currentForm"]["selectedProjectID"]); Response.Cookies["currentForm"]["selectedProjectID"] = Request.Cookies["currentForm"]["selectedProjectID"]; Note that I am setting the Response cookie in all the forms after I read the Request cookie. Is this necessary? Do the Request cookies copy to the Response automatically? I'm setting no properties on the cookies and create them this way: Response.Cookies["currentForm"]["selectedProjectID"] = someGuid.ToString(); The intention is that these are temporary header cookies, not persisted on the client any longer than the browser session. I ask this since I don't often write websites.

  • 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 }

  • Override onDraw to change how the drawing occurs (Android)

    - by Casebash
    I want to change how my UI elements display, so I am overriding onDraw. The following code allows me to change a View to be drawn using PorterDuff.Mode.DARKEN. Unfortunately, this method involves creating a bitmap the size of the entire screen, then drawing to it then drawing this large bitmap the main screen again, for each UI element. This isn't at all efficient. Is it possible to achieve this in a more effecient way? @Override protected void onDraw(Canvas canvas) { //TODO: Reduce the burden from multiple drawing Bitmap bitmap=Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Config.ARGB_8888); Log.e("tmp",canvas.getClipBounds().toString()); Canvas offscreen=new Canvas(bitmap); super.onDraw(offscreen); //Then draw onscreen Paint p=new Paint(); p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DARKEN)); canvas.drawBitmap(bitmap, 0, 0, p); }

  • 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.

  • How to add on to an existing onclick event?

    - by Corey Sarnia
    I'm currently writing a Greasemonkey script for a page, so I can't modify the script myself. There is a form submit button on the page. When you click this button, it executes some fancy AJAX calls and such to update the page and do serverside things. What I'm trying to is basically set a "lastClick" value when the button is clicked. I want to add the code GM_setValue("lastClicked", (new Date()).getTime().toString()) to store the last time the button was clicked (for future uses of the script, it will actually do something with this date). How exactly can I accomplish this?

  • How can I generate an RFC1123 Date string, from C code (Win32)

    - by Cheeso
    RFC1123 defines a number of things, among them, the format of Dates to be used in internet protocols. HTTP (RFC2616) specifies that date formats must be generated in conformance with RFC1123. It looks like this: Date: Wed, 28 Apr 2010 02:31:05 GMT How can I generate an RFC1123 time string from C code, running on Windows? I don't have the use of C# and DateTime.ToString(). I know I could write the code myself, to emit timezones and day abbreviations, but I'm hoping this already exists in the Windows API. Thanks.

  • allow only distinct values in ComboBox

    - by Ravinder Gangadher
    In my project, I am trying to populate ComboBox from DataSet. I succeeded in populating but the values inside the ComboBox are not distinct (Because it just showing the values present in DataSet). I cant bind the ComboBox to DataSet because I am adding "Select" text at first of populating the values. Here is my code. ComboBox --> cmb DataSet --> ds DataSet Column Name --> value(string) cmb.Items.Clear(); cmb.Items.Add("Select"); for (int intCount = 0; intCount < ds.Tables[0].Rows.Count; intCount++) { cmb.Items.Add(ds.Tables[0].Rows[intCount][value].ToString()); } cmb.SelectedIndex = 0; My question is how to allow distinct values (or restrict duplicate values) inside the ComboBox.

  • EF Query using .Contains() and .ToLowerInvariant() Results in no matches when match is found at the end of a string

    - by MyNameIsJob
    Is it possible to step into a linq query? I have a linq to entity framework 4 query in it's simplest form: List = List.Where(f => f.Value.ToString().ToLowerInvariant().Contains(filter.ToLowerInvariant())); It's a query against an Entity Framework DbContext and I'm having trouble seeing why it works for something like: List searching for 001 yields no results against the following list Test001 Test002 Test003 Test004 However any other search yields results (Such as t00 or Test) Update Basically I'm looking for why a query such as the above wouldn't return a result when I'm using a contains and the value matches the end of a string vs just the middle or begining. It's really confusing. OK, it appears to have something to do with ToLowerInvariant() - when I removed that method it works just fine.

  • Is it possible to create an enum whose instance can't be created but can be used for readonly purpos

    - by Shantanu Gupta
    I created an enum where I stored some table names. I want it to be used to get the name of the table like ds.Tables[BGuestInfo.TableName.L_GUEST_TYPE.ToString()]. public class a { public enum TableName : byte { L_GUEST_TYPE = 0 ,L_AGE_GROUP = 1 ,M_COMPANY = 2 ,L_COUNTRY = 3 ,L_EYE_COLOR = 4 ,L_GENDER = 5 ,L_HAIR_COLOR = 6 ,L_STATE_PROVINCE = 7 ,L_STATUS = 8 ,L_TITLE = 9 ,M_TOWER = 10 ,L_CITY = 11 ,L_REGISTER_TYPE = 12 } } class b { a.TableName x; //trying to restrict this ds.Tables[a.TableName.L_GUEST_TYPE] //accessible and can be used like this } This is my enum. Now I have not created any instance of this enum so that no one can use it for other than read only purpose. For this enum to be accessible in outer classes as well I have to make it public which means some outer class can create its object as well. So what can i do so as to restrict its instance creation.
