  • display wait gif until image is fully loaded

    - by Dimitris Baltas
    Most popular browsers, while rendering an image, they display it line-by-line top-to-bottom as it loads. I have a requirement that a wait gif should be displayed while the image is loading. When the image is fully loaded then it should be displayed instead of the wait gif. If it helps, the site is http://farros.gr, main image: /images/bg.jpg and the div containing the image is named #main-content-image.

  • Unfold vCard lines in shell

    - by l0b0
    vCard lines can be folded by inserting "\r\n " (that's a space at the start of the new line), but I'm struggling to unfold them with the line-oriented GNU tools (sed, cut). Any ideas? Effectively, from the string foo bar baz ban bay bal it must return foobar baz banbaybal

  • Looking for a good text parsing library for C#

    - by Chris Stewart
    Has anyone run across a quality library that will parse, line by line, CSV, tab-delimited, and Excel files? I've started to do it manually but have noticed some of the intricacies in parsing a comma-delimited file. Such as situations where a cell has a comma in it as part of the data (blah,\"LastName, Jr.\",blah,blah).

  • tmpfile and gzip combination problem

    - by Vojtech R.
    I have problem with this code: file = tempfile.TemporaryFile(mode='wrb') file.write(base64.b64decode(data)) file.flush() os.fsync(file) # file.seek(0) f = gzip.GzipFile(mode='rb', fileobj=file) print f.read() I dont know why it doesn't print out anything. If I uncomment file.seek then error occurs: File "/usr/lib/python2.5/gzip.py", line 263, in _read self._read_gzip_header() File "/usr/lib/python2.5/gzip.py", line 162, in _read_gzip_header magic = self.fileobj.read(2) IOError: [Errno 9] Bad file descriptor Just for information this version works fine: x = open("test.gzip", 'wb') x.write(base64.b64decode(data)) x.close() f = gzip.GzipFile('test.gzip', 'rb') print f.read()

  • Inline comments for bash?

    - by Lajos Nagy
    I'd like to be able to comment out a single flag in a one-line command. Bash only seems to have `from # till end-of-line' comments. I'm looking at tricks like: ls -l $([ ] && -F is turned off) -a /etc It's ugly, but better than nothing. Anybody has any better suggestions?

  • Difference between WinMain and wWinMain

    - by Sherwood Hu
    The only difference is that Winmain takes char* for lpCmdLine parameter, while wWinMain takes wchar_t*. On Windows XP, if an application entry is WinMain, does Windows convert the command line from Unicode to Ansi and pass to the application? If the command line parameter must be in Unicode (for example, Unicode file name, conversion will cause some characters missing), does that mean that I must use wWinMain as the entry function?

  • How to output formatted HTML from PHP?

    - by Tim
    I like to format all my HTML with tabs for neatness and readability. Recently I started using PHP and now I have a lot of HTML output that comes from in between PHP tags. Those output lines all line up one the left side of the screen. I have to use /n to make a line go to the next. Is there anything like that for forcing tabs, or any way to have neat HTML output coming from PHP?

  • Executing Javascript without a browser?

    - by Daniel
    I am looking into Javascript programming without a browser. I want to run scripts from the Linux or Mac OS X command line, much like we run any other scripting language (ruby, php, perl, python...) $ javascript my_javascript_code.js I looked into spider monkey (Mozilla) and v8 (Google), but both of these appear to be embedded. Is anyone using Javascript as a scripting language to be executed from the command line? If anyone is curious why I am looking into this, I've been poking around node.js

  • Error while creating tests in Visual Studio

    - by Benjol
    When I try to generate a unit test for the following method (in a public static class) private static string[] GetFields(string line, char sep) { char[] totrim = { '"', ' ' }; return line.Split(sep).Select(col => col.Trim(totrim)).ToArray(); } The Tests output says: While trying to generate your tests, the following errors occurred: This method or property cannot be called within an event handler. It works if I make the function public - I've tried running Publicize.exe manually, it doesn't complain, but doesn't make any difference either.

  • How can I call VC# webservice methods without ArgumentException?

    - by Zarius
    Currently, I'm trying to write a small tray application that will show the status and provide control of a server-side application exposed over webservice. The webservice only has 3 operations: start, stop and status. When I call any of these operations in code, they throw an ArgumentException citing "An item with the same key has already been added". I am compiling the webservice on Visual C# Express 2008, and .NET 3.5. The Code: private TelnetConnClient Conn { get { return new TelnetConnClient(); } } private bool Connected //call webservice operations { get { return Conn.Status(); } set { if(value) Conn.Start(); else Conn.Stop(); } } The Stacktrace: A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) at System.ServiceModel.TransactionFlowAttribute.ApplyBehavior(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.TransactionFlowAttribute.System.ServiceModel.Description.IOperationBehavior.AddBindingParameters(OperationDescription description, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection parameters) at System.ServiceModel.Description.DispatcherBuilder.BuildProxyBehavior(ServiceEndpoint serviceEndpoint, BindingParameterCollection& parameters) at System.ServiceModel.Channels.ServiceChannelFactory.BuildChannelFactory(ServiceEndpoint serviceEndpoint) at System.ServiceModel.ChannelFactory.CreateFactory() at System.ServiceModel.ChannelFactory.OnOpening() at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.ChannelFactory.EnsureOpened() at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via) at System.ServiceModel.ChannelFactory`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannel() at System.ServiceModel.ClientBase`1.CreateChannelInternal() at System.ServiceModel.ClientBase`1.get_Channel() at KordiaConnect.ferries.TelnetConnClient.Start() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Service References\ferries\Reference.cs:line 86 at coldshark.ferries.Main.set_Connected(Boolean value) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 22 at coldshark.ferries.Main.<.ctor>b__0(Object sender, EventArgs e) in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 43 at System.Windows.Forms.NotifyIcon.OnClick(EventArgs e) at System.Windows.Forms.NotifyIcon.WmMouseUp(Message& m, MouseButtons button) at System.Windows.Forms.NotifyIcon.WndProc(Message& msg) at System.Windows.Forms.NotifyIcon.NotifyIconNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.PeekMessage(MSG& msg, HandleRef hwnd, Int32 msgMin, Int32 msgMax, Int32 remove) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run() at coldshark.ferries.Main..ctor() in C:\My Dropbox\Coding\RTF\KordiaConnect\KordiaConnect\Main.cs:line 55 I can just call the webservice from the web interface, but this application will give me a handy status notification icon, and I'd really love to know why the out-of-the-box auto-generated code fails for no particular reason.

  • How to restrict operations to certain lines?

    - by Ayman
    I have to work on some relatively huge code files in vim. How do I restrict some operations like find-next normal-n and others to a certain function / block? How would I visually know if I'm within that block or outside it? Looking and line numbers seems awkward, specially that the line numbers I need to work with are generally 5 digits long!

  • "Null" is null or not an object error in IE javascript

    - by user89691
    The following code executes fine in Firefox and Chrome, but gives an error: 'null' is null or not an object when executed in Internet Explorer. if (xmlhttp.responseXML != null) { var xmlDoc = xmlhttp.responseXML.documentElement ; var ResultNodes = xmlDoc.getElementsByTagName ("Result") ; <---- error here if (ResultNodes != null) { (I would have thought the line after the one indicated would be more likely to return the error but the debugger says the run-time error is at the line indicated) Any ideas why?

    I was wondering if there was a way I could program and compile .net applications (c#, asp.net mvc) from a usb stick on any laptop I plugged in. I am lookinjg for a solution that does not have me installing programs on the laptop, so I have to be able to run an ide or editor from an exe and compile presumably from command line. Was also wondering if I can run MS test projects from command line to check tests passed etc. Thanks
