  • Set predefine form value (webbrowser control)

    - by Khou
    Hi I want to load my windows form: web browser thats using the webbrowser control, It would load a web page, and load my defination and search for elements that has been define, it will then assign the default values and these values can not be changed by the end user. Example If my application finds "FirstName" it would always assign the value "John" If my application finds "LastName" it would always assign the value "Smith" (these values should not be changed by the end user). Here's how to do it in HTML/JAVASCRIPT, but how do i do this in a windows form? HTML <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>page title</title> <script script type="text/javascript" src="demo1.js"></script> </head> <body onload="def(document.someform, 'name', 'my default name value');"> <h2 style="color: #8e9182">test form title</h2> <form name="someform" id="someform_frm" action="#"> <table cellspacing="1"> <tr><td><label for="name">NameX: </label></td><td><input type="text" size="30" maxlength="155" name="name" onchange="def(document.someform, 'name', 'my default name value');"></td></tr> <tr><td><label for="name2">NameY: </label></td><td><input type="text" size="30" maxlength="155" name="name2"></td></tr> <tr><td colspan="2"><input type="button" name="submit" value="Submit" onclick="showFormData(this.form);" ></td></table> </form> </body> </html> JAVASCRIPT function def(oForm, element_name, def_txt) { oForm.elements[element_name].value = def_txt; }

  • Improve Efficiency for This Text Processing Code

    - by johnv
    I am writing a program that counts the number of words in a text file which is already in lowercase and separated by spaces. I want to use a dictionary and only count the word IF it's within the dictionary. The problem is the dictionary is quite large (~100,000 words) and each text document has also ~50,000 words. As such, the codes that I wrote below gets very slow (takes about 15 sec to process one document on a quad i7 machine). I'm wondering if there's something wrong with my coding and if the efficiency of the program can be improved. Thanks so much for your help. Code below: public static string WordCount(string countInput) { string[] keywords = ReadDic(); /* read dictionary txt file*/ /*then reads the main text file*/ Dictionary<string, int> dict = ReadFile(countInput).Split(' ') .Select(c => c) .Where(c => keywords.Contains(c)) .GroupBy(c => c) .Select(g => new { word = g.Key, count = g.Count() }) .OrderBy(g => g.word) .ToDictionary(d => d.word, d => d.count); int s = dict.Sum(e => e.Value); string k = s.ToString(); return k; }

  • Correlating traditional Windows joystick axes with HID

    - by Wade Williams
    I'm a bit confused on the description of joystick axes and I'm hoping that someone has a link or document which could help clear my confusion. I'm not a Windows guy, so trying to port some traditional Windows gameport code has me a bit confused. We all know about the common first three axes: X Y Z My understanding was that in the gameport-style interface the three other axes are: R U V However, looking in my IOHIDUsageTables (OS X), I see: kHIDUsage_GD_X = 0x30, /* Dynamic Value */ kHIDUsage_GD_Y = 0x31, /* Dynamic Value */ kHIDUsage_GD_Z = 0x32, /* Dynamic Value */ kHIDUsage_GD_Rx = 0x33, /* Dynamic Value */ kHIDUsage_GD_Ry = 0x34, /* Dynamic Value */ kHIDUsage_GD_Rz = 0x35, /* Dynamic Value */ kHIDUsage_GD_Vx = 0x40, /* Dynamic Value */ kHIDUsage_GD_Vy = 0x41, /* Dynamic Value */ kHIDUsage_GD_Vz = 0x42, /* Dynamic Value */ kHIDUsage_GD_Vbrx = 0x43, /* Dynamic Value */ kHIDUsage_GD_Vbry = 0x44, /* Dynamic Value */ kHIDUsage_GD_Vbrz = 0x45, /* Dynamic Value */ kHIDUsage_GD_Vno = 0x46, /* Dynamic Value */ This has me a bit confused due to the three R axis (though that does not appear to be uncommon) and the lack of a U axis. Two questions: 1) Can anyone confirm to what axis the traditional U axis would be? I saw one document describe it as "the axis for rudder pedals" leading me to believe it would be Rz. 2) Can anyone describe in more detail the typical usages of the V and Vbr axes? I understand the descriptions are "vector" and "relative vector,' respectively, but I'm having difficult visualizing what that means in terms of a physical device. All enlightenment and documentation pointers welcome.

  • javascript addEventListener onStateChange not working in IE

    - by user347456
    Hi, I have two colorbox popup boxes which show a youtube video in each. When they're finished playing, I'm trying to have them automatically close the colorbox window. This code below works perfect in firefox, but in IE I can't get addEventListener to work. I've tried attachEvent with no success. Can anybody offer any suggestions as to how to solve this? It seems simple but I'm exhausted trying to find a solution. By the way, this is my first time as stackoverflow and it's very impressive. var params = { allowScriptAccess: "always" }; var atts = { id: "ytplayer1" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO1&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo1", "popupVideoContainer1", "640", "385", "8", null, null, params, atts); var params2 = { allowScriptAccess: "always" }; var atts2 = { id: "ytplayer2" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO2&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo2", "popupVideoContainer2", "640", "385", "8", null, null, params2, atts2); function onYouTubePlayerReady(playerId) { if(playerId == 'ytvideo1'){ var ytplayer = document.getElementById('ytplayer1'); ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if(playerId == 'ytvideo2'){ var ytplayer = document.getElementById("ytplayer2"); //ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); if (ytplayer.addEventListener) { ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if (ytplayer.attachEvent) { ytplayer.attachEvent("onStateChange", onytplayerStateChange); } } } function onytplayerStateChange(newState) { if(newState == 0){ $.fn.colorbox.close(); } }

  • SignalR recording when a Web Page has closed

    - by Benjamin Rogers
    I am using MassTransit request and response with SignalR. The web site makes a request to a windows service that creates a file. When the file has been created the windows service will send a response message back to the web site. The web site will open the file and make it available for the users to see. I want to handle the scenario where the user closes the web page before the file is created. In that case I want the created file to be emailed to them. Regardless of whether the user has closed the web page or not, the message handler for the response message will be run. What I want to be able to do is have some way of knowing within the response message handler that the web page has been closed. This is what I have done already. It doesnt work but it does illustrate my thinking. On the web page I have $(window).unload(function () { if (event.clientY < 0) { // $.connection.hub.stop(); $.connection.exportcreate.setIsDisconnected(); } }); exportcreate is my Hub name. In setIsDisconnected would I set a property on Caller? Lets say I successfully set a property to indicate that the web page has been closed. How do I find out that value in the response message handler. This is what it does now protected void BasicResponseHandler(BasicResponse message) { string groupName = CorrelationIdGroupName(message.CorrelationId); GetClients()[groupName].display(message.ExportGuid); } private static dynamic GetClients() { return AspNetHost.DependencyResolver.Resolve<IConnectionManager>().GetClients<ExportCreateHub>(); } I am using the message correlation id as a group. Now for me the ExportGuid on the message is very important. That is used to identify the file. So if I am going to email the created file I have to do it within the response handler because I need the ExportGuid value. If I did store a value on Caller in my hub for the web page close, how would I access it in the response handler. Just in case you need to know. display is defined on the web page as exportCreate.display = function (guid) { setTimeout(function () { top.location.href = 'GetExport.ashx?guid=' + guid; }, 500); }; GetExport.ashx opens the file and returns it as a response. Thank you, Regards Ben

  • How can I transform XML to invalid XML using XSLT?

    - by Damovisa
    I need to transform a valid XML document to the OFX v1.0.2 format. This format is more or less XML, but it's technically invalid and therefore cannot be parsed as XML. I'm having trouble getting my Xml transformation working because the .Net XslCompiledTransform object insists on interpreting the XSL as an XML document (which is fair enough). If I escape the xml-ish tags using &lt; and &gt, they get removed when I download the file. Here's the start of my XSLT: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="text"></xsl:output> <xsl:param name="currentdate"></xsl:param> <xsl:template match="Transactions"> OFXHEADER:100 DATA:OFXSGML VERSION:102 SECURITY:NONE ENCODING:USASCII CHARSET:1252 COMPRESSION:NONE OLDFILEUID:NONE NEWFILEUID:NONE <OFX> <SIGNONMSGSRSV1> <SONRS> <STATUS> <CODE>0 <SEVERITY>INFO </STATUS> <DTSERVER><xsl:value-of select="$currentdate" /> <LANGUAGE>ENG Any suggestions?

  • Silverlight 4 Default Button Service

    - by Mark Cooper
    For a few months I have been successfully using David Justices Default Button example in my SL 3 app. This approach is based on an attached property. After upgrading to SL4, the approach no longer works, and I get a XAML exception: "Unknown parser error: Scanner 2148474880" Has anyone succesfully used this (or any other) default button attached behaviours in SL4? Is there any other way to achieve default button behaviour in SL4 with the new classes that are available? Thanks, Mark

  • WPF WebBrowser: How to set element click event?

    - by Ralph
    I've figured out how to make everything red as soon as the page is finished loading: private void webBrowser1_LoadCompleted(object sender, NavigationEventArgs e) { var doc = (IHTMLDocument2)webBrowser1.Document; foreach (IHTMLElement elem in doc.all) { elem.style.backgroundColor = "#ff0000"; } } Now what if I want to make the element only change color when it's clicked? I see that elem has an onclick property, but it's type is dynamic so I don't know what to do with it. The documentation is pretty useless.

  • Jquery galleria - make the first image in the gallery appear automatically

    - by Agrajag
    I've added the excellent galleria-plugin to a website I'm working on. However unlike the demo, I've been unable to make the first image display automatically on page-load. Currently, you have to click an image, before one will appear, after that everything works as expected. And yes, I've tried setting the class of the first image to "active", but without that having any effect. Is there anything obvious I'm missing ? There's a live example at: http://kaciekimber.co.za/property/r8453d

  • Silverlight Dataform validation doesn't work

    Hi I can't get dataform and it's controls to catch exceptions when validating. Fir instance, I have: <PasswordBox Password="{Binding Password,Mode=TwoWay,NotifyOnValidationError=true,ValidatesOnExceptions=true}" /> All required properties are set to true. In the setter of my Password property I throw a ValidationException upon failed validation, but the data form doesn't catch it, it just causes the application to crash as if it were a normal exception. Am I doing something wrong? Thanks

  • Insert video clip in a lyx presentation and play it in GNU/Linux.

    - by Orjanp
    How can I insert a video clip into a presentation created in Lyx? Have seen http://www.latex-community.org/forum/viewtopic.php?f=19&t=48. It works, but there the video starts in the background in an external player. I would prefer it to be played in the presentation itself. If an external player is used it it should at least start in the foreground. But the presentation takes the foreground. Using evince in GNU/linux as pdf viewer. Beamer is used as a presentation template. Is it possible to play a video file in an embedded player in the presentation itself? Created an example presentation.

  • Overflow in DIV by wrapping not scrollbars

    Given a DIV with a fixed width, is there a way to have it use as much vertical space as it needs by wrapping the content (which is plain text)? The CSS "overflow" property provides for scrollbars (overflow:scroll) and chopping content (overflow:hidden) but that's not what I want. Help? Thanks

  • Use native HBitmap in C# while preserving alpha channel/transparency. Please check this code, it works on my computer...

    - by David
    Let's say I get a HBITMAP object/handle from a native Windows function. I can convert it to a managed bitmap using Bitmap.FromHbitmap(nativeHBitmap), but if the native image has transparency information (alpha channel), it is lost by this conversion. There are a few questions on Stack Overflow regarding this issue. Using information from the first answer of this question (How to draw ARGB bitmap using GDI+?), I wrote a piece of code that I've tried and it works. It basically gets the native HBitmap width, height and the pointer to the location of the pixel data using GetObject and the BITMAP structure, and then calls the managed Bitmap constructor: Bitmap managedBitmap = new Bitmap(bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); As I understand (please correct me if I'm wrong), this does not copy the actual pixel data from the native HBitmap to the managed bitmap, it simply points the managed bitmap to the pixel data from the native HBitmap. And I don't draw the bitmap here on another Graphics (DC) or on another bitmap, to avoid unnecessary memory copying, especially for large bitmaps. I can simply assign this bitmap to a PictureBox control or the the Form BackgroundImage property. And it works, the bitmap is displayed correctly, using transparency. When I no longer use the bitmap, I make sure the BackgroundImage property is no longer pointing to the bitmap, and I dispose both the managed bitmap and the native HBitmap. The Question: Can you tell me if this reasoning and code seems correct. I hope I will not get some unexpected behaviors or errors. And I hope I'm freeing all the memory and objects correctly. private void Example() { IntPtr nativeHBitmap = IntPtr.Zero; /* Get the native HBitmap object from a Windows function here */ // Create the BITMAP structure and get info from our nativeHBitmap NativeMethods.BITMAP bitmapStruct = new NativeMethods.BITMAP(); NativeMethods.GetObjectBitmap(nativeHBitmap, Marshal.SizeOf(bitmapStruct), ref bitmapStruct); // Create the managed bitmap using the pointer to the pixel data of the native HBitmap Bitmap managedBitmap = new Bitmap( bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); // Show the bitmap this.BackgroundImage = managedBitmap; /* Run the program, use the image */ MessageBox.Show("running..."); // When the image is no longer needed, dispose both the managed Bitmap object and the native HBitmap this.BackgroundImage = null; managedBitmap.Dispose(); NativeMethods.DeleteObject(nativeHBitmap); } internal static class NativeMethods { [StructLayout(LayoutKind.Sequential)] public struct BITMAP { public int bmType; public int bmWidth; public int bmHeight; public int bmWidthBytes; public ushort bmPlanes; public ushort bmBitsPixel; public IntPtr bmBits; } [DllImport("gdi32", CharSet = CharSet.Auto, EntryPoint = "GetObject")] public static extern int GetObjectBitmap(IntPtr hObject, int nCount, ref BITMAP lpObject); [DllImport("gdi32.dll")] internal static extern bool DeleteObject(IntPtr hObject); }

  • x-dom-event-stream in Opera 10 Only Working on First Event

    - by Brad
    I have a python script (in the CherryPy framework) that sends Event: and data: text as this Opera blog post describes to a client browser. The javascript that recieves the x-dom-event-stream content is almost identical to what they show in the blog post. However, the browser displays only the first event sent. Anyone know what I'm missing? I tried a few older versions of Opera and found that it works in Opera 9.52 but not in any newer versions. What did they change? Here is the python code: class dumpData(object): def index(self): cherrypy.response.headers['Content-Type'] = "application/x-dom-event-stream" def yieldData(): i = 0 while 1: yield "Event: count\n" yield "data: " yield i yield "\n\n" i = i + 1 time.sleep(3); return yieldData() index._cp_config = {'response.stream': True} index.exposed = True And here is the javascript/html. Making a request to /data/ runs the python function above. <head> <script> onload = function() { document.getElementById("count").addEventListener("cout", cout, false); } function count(e) { document.getElementById("stream").firstChild.nodeValue = e.data; } </script> <event-source id="count" src="/data/"> </head> <body> <div id="stream"></div> </body> Opening the direct /data/ url in Firefox saves the stream to a file. So I know the output is in the correct format and that the stream works at all.
