  • How to get time difference in milliseconds

    - by jason45
    Hi, I can't wrap my brain around this one so I hope someone can help. I have a song track that has the song length in milliseconds. I also have the date the song played in DATETIME format. What I am trying to do is find out how many milliseconds is left in the song play time. Example $tracktime = 219238; $dateplayed = '2011-01-17 11:01:44'; $starttime = strtotime($dateplayed); I am using the following to determine time left but it does not seem correct. $curtime = time(); $timeleft = $starttime+round($tracktime/1000)-$curtime; Any help would be greatly appreciated.

  • Form graphics not set when form loads

    - by Jimmy
    My form has a group box which contains two overlapping rectangles. The form's other controls are two sets of four numeric up down controls to set the rectangles' colors. (nudF1,2,3 and 4 set the rectangle that's in front, and nudB1,2,3 and 4 set the rectangle that's behind.) Everything works fine, except that the rectangles do not display the colors set in the numeric up downs when the form first loads. The numeric up down controls' ChangeValue events all call the ShowColors() method. The form's Load event calls the csColorsForm_Load() method. Any suggestions? namespace csColors { public partial class csColorsForm : Form { public csColorsForm() { InitializeComponent(); } private void csColorsForm_Load(object sender, EventArgs e) { this.BackColor = System.Drawing.Color.DarkBlue; SetColors(sender, e); } private void SetColors(object sender, EventArgs e) { Control control = (Control)sender; String ctrlName = control.Name; Graphics objGraphics; Rectangle rect1, rect2; int colorBack, colorFore; objGraphics = this.grpColor.CreateGraphics(); // If calling control is not a forecolor control, paint backcolor rectangle if (ctrlName.Substring(0,4)!="nudF") { colorBack = int.Parse(SetColorsB("nudB"), NumberStyles.HexNumber); SolidBrush BrushB = new SolidBrush(Color.FromArgb(colorBack)); rect1 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushB, rect1); } // Always paint forecolor rectangle colorFore = int.Parse(SetColorsB("nudF"), NumberStyles.HexNumber); SolidBrush BrushF = new SolidBrush(Color.FromArgb(colorFore)); rect2 = new Rectangle(this.grpColor.Left, this.grpColor.Top, this.grpColor.Width, this.grpColor.Height); objGraphics.FillRectangle(BrushF, rect2); objGraphics.Dispose(); } private string SetColorsB(string nam) { string txt=""; for (int n = 1; n <= 4; ++n) { var ud = Controls[nam + n] as NumericUpDown; int hex = (int)ud.Value; txt += hex.ToString("X2"); } return txt; } private void btnClose_Click(object sender, EventArgs e) { this.Close(); } } }

  • What's the difference between the [OptionalField] and [NonSerialized]

    - by IbrarMumtaz
    I came across this question on transcender: What should you apply to a field if its value is not required during deserialization? Me = [NonSerialized], ANSWER = [OptionalField] My gut reaction was NonSerialised, I have no idea why but in the space of 5 seconds thats what I thought but to my surprise, Transcender says I am wrong. OK fair enough .... but why? looking more closely at the question I have a good idea what to look out for as far as the [Nonseralized] attribute is concerned but still I would really like this clearing up. As far as I can tell the former has relationship with versioning conflicts between newer and older versions of the same assembly. The later is more concerned with not serializing a field FULLSTOP. Is there anything else that might pick these two apart? MSDN does not really say much about this as they both are used on the BinaryFormatters and SoapFormatter with the XMLFormatter using the XMLIgnoreAttribute. My second question is can you mix and match either one of the two attributes ... I am yet to use them as I have not had an excuse to mess about with them. So my curiosity can only go so far. Just throwing this one out there, but does my answer have something to do with the way [OnDeserialized] and the IdeserilizationCallback interface is implemented???? Am guessing here .... Thanks In Advance UPDATE: I know that optional field attribute does not serialize the value held by a data member but NonSerialized will not even serialise the data member or its value. That sounds about a right???? That's all I got on these two attributes.

  • Alias one set of Subdomains to another

    - by Schneems
    I have to domains that I want to effectively mirror one another on select subdomains. Let's say they are pirates.com and ninjas.com and i want ninjas to mirror the content on pirates. When I visit foo.ninjas.com I want to see the content on foo.pirates.com. Due to app restrictions I need to do this in DNS for an undefined number of subdomains. I was under the impression i could do this with a CNAME, but it appears that setting a CNAME for * subdomain of the ninjas.com domain to point to pirates.com will make any subdomain of ninjas.com point at pirates.com instead of the associated subdomain. I.e. foo.ninjas.com would reference pirates.com instead of foo.pirates.com. Is there a way to do this using DNS? Am I missing something basic?

  • How to set Visual Studio to Publish pdf files

    - by TheAlbear
    Is there a way to set visual studio to publish all pdf files? I know that you can set each indivdual pdf file in a project with the "Copy to Outpub Directory" property. But that means doing the same thing 100's of times for my current project, is there a way to change a global setting to do the same thing?

  • Number of elements in Python Set

    - by Tim
    I have a list of phone numbers that have been dialed (nums_dialed). I also have a set of phone numbers which are the number in a client's office (client_nums) How do I efficiently figure out how many times I've called a particular client (total) For example: >>>nums_dialed=[1,2,2,3,3] >>>client_nums=set([2,3]) >>>??? total=4 Problem is that I have a large-ish dataset: len(client_nums) ~ 10^5; and len(nums_dialed) ~10^3.

  • set a global environment variable in linux that sticks when going root

    - by Scott
    When I SSH into a linux box, I want to have the /etc/profile file save the results of the whoami command to a global environment variable. if I were to go root with the command sudo su -, I do not want that command to run again when gonig root, I want it to stick with the result of whoami as my regular username from before I went root, and I need to access that variable as the root user even though it will run the /etc/profile file again when I go root. What can I do to only run that command once in the /etc/profile command?

  • what's the difference between DEFAULT_SIZE and PREFERRED_SIZE?

    - by CD1
    hi, I'm using Swing GroupLayout and I'm confused about the values GroupLayout.DEFAULT_SIZE and GroupLayout.PREFERRED_SIZE. I never know when to use each one of them in methods like GroupLayout.addComponent(Component, int, int, int). suppose I have this code: GroupLayout l = ...; l.setHorizontalGroup(l.createSequentialGroup() .addComponent(tf1) .addComponent(tf2)); l.setVerticalGroup(l.createParallelGroup() .addComponent(tf1) .addComponent(tf2)); there are two JTextFields on a single line laid out with GroupLayout (one sequential group horizontally and one parallel group vertically). if I resize the window now, both components get the available space (50% each). but I want only the first text field to grow/shrink horizontally and only the second text field to grow/shrink vertically. what values of min, pref and max should I use to accomplish that? I know I can just try it and see what combination works but I'd like to know the reasoning behind this problem.

  • Can't set session.http_only for php under Plesk 11

    - by TheFoOL
    I want to enable session.cookie_httponly for my domain. I added these lines for my domain (in additional configuration directives): session.cookie_httponly = On error_log = error.log Error log works fine (a file is created) whereas session.cookie_httponly doesn't (according to phpinfo()). But why not? I use Plesk 11 on Ubuntu Server 12.04. PHP as FastCGI. PHP 5.3.10-1ubuntu3.4. Safe mode is off. Domain is associated to a dedicated IP address. Website powered by Joomla 2.5.7.

  • Need to set up a proxy on Linksys E3200 to filter home internet

    - by Justin Amberson
    the fact that I have a Linksys E3200 may not be important. I can configure the router through the web interface, but I don't know the things I will be toggling are called. I already do simple port forwarding to access applications on my Mac remotely. So router admin is not something I technically need explained. I'm looking to running a proxy on my home computer, that filters all HTTP traffic that goes through my router. So if my daughter is on her iPad and accesses Safari, my Mac will be the judge of the validity of the request. I need something like NetNanny I guess, but local. Actually, anything that can just filter all port 80 traffic that runs locally, but maybe validates with a password? I truly truly hope this question falls within the bounds of Serverfault. I'm not a total internet newb but I'm at a loss for what to Google. If possible answer this question: Is there a webapp that can listen on port 80, and validate requests to port 80 with a password? If so, can I forward all traffic on port 80 to my Mac, to be re-routed to the user? Is this the same as a VPN? Thank you for your help. Justin

  • difference between 2 pieces Python code

    - by draw
    Hello, I'm doing an exercise as following: # B. front_x # Given a list of strings, return a list with the strings # in sorted order, except group all the strings that begin with 'x' first. # e.g. ['mix', 'xyz', 'apple', 'xanadu', 'aardvark'] yields # ['xanadu', 'xyz', 'aardvark', 'apple', 'mix'] # Hint: this can be done by making 2 lists and sorting each of them # before combining them. sample solution: def front_x(words): listX = [] listO = [] for w in words: if w.startswith('x'): listX.append(w) else: listO.append(w) listX.sort() listO.sort() return listX + listO my solution: def front_x(words): listX = [] for w in words: if w.startswith('x'): listX.append(w) words.remove(w) listX.sort() words.sort() return listX + words as I tested my solution, the result is a little weird. Here is the source code with my solution: http://dl.dropbox.com/u/559353/list1.py. You might want to try it out.

  • Unable to set "always open with" checkbox

    - by bas
    Configuration: windows 8 (desktop) firefox (latest version) I've been trying to figure out how to enable the checkbox to "always open with ... application for file type", for quite a while without any luck. Can anybody explain to me how I can enable the checkbox (see red rectangle). It's in Dutch, but I hope you recognize the dialog. Tried so far: - default programs (control panel) - HKCU/Microsoft/.../FileExts: remove the UserChoice (but it was already removed, so no luck there either) Thanks a lot in advance

My goal is to make .htaccess work on the server with plesk and with the directory C:\inetpub\vhosts.
