• Rendering a different controller and action while keeping errors

  - by DerNalia

  I have a form in one controller(A) that renders a partial from another controller(B), and stays on A's edit page during editing / updating etc. However... When the partial form form controller B has an error, the error doesn't show up on A's edit page right now, if there is an error, I am doing (in controller B's update method) redirect_to :controller => "A", :action => "edit" and then this is built in... but I don't know what to do with it... the error needs to be sent to controller A... but.. it doesn't format.xml { render :xml => @varFromB.errors, :status => :unprocessable_entity } thanks

• VBScript Permission Denied on CopyFile

  - by Chris

  I'm running a VBScript in SQL Agent but I get a 'Permission Denied' on line 34 (the first copy attempt). I've run this script outside SQL Agent with no problems Function Main() Const SourceDrive As String = "X:\" Dim fso Dim Today Dim FileName Dim FromFile Dim FromDrive Dim ArchivePath Set fso = CreateObject("Scripting.FileSystemObject") Today = Format(Now, "yyyyMMdd") 'To add more sources just add them to the array list Dim Sources() As Variant Sources() = Array("Item1", _ "Item2") 'To add more targets just add them to the array list Dim Targets() As Variant Targets() = Array("C:\Users\myalias\Desktop\MyToFolder", _ "C:\Users\myalias\Desktop\MyToFolder2") For i = 0 To UBound(Sources) FileName = "WebSurveyAlertCallbacks_" & Sources(i) & "_" & Today & ".xls" FromDrive = fso.BuildPath(SourceDrive, Sources(i)) FromFile = fso.BuildPath(FromDrive, FileName) ArchivePath = fso.BuildPath(FromDrive, "Archive") If fso.FileExists(FromFile) Then For t = 0 To UBound(Targets) fso.CopyFile FromFile, fso.BuildPath(Targets(t), FileName), True Next fso.CopyFile FromFile, fso.BuildPath(ArchivePath, FileName), True fso.DeleteFile FromFile End If Next Set fso = Nothing Main = DTSTaskExecResult_Success End Function

• Help with IE bugs when writing JSON via an ASPX response

  - by Jereme

  I have an ASPX page that I am using to write JSON. It works great in Firefox and Chrome, but when I try and use it in IE 8 it gives me an "The XML page cannot be displayed" error instead of allowing jQuery to load the JSON being written by the response. Any ideas? Here is what my code looks like: protected override void OnLoad(EventArgs e) { Response.Clear(); Response.ClearHeaders(); Response.ContentType = "application/json"; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Write(string.Format("[ {{ \"Foo\": \"{0}\", \"bar\": \"{1}\" }} ]", "Foo Content", "Bar Content")); Response.End(); }

• Build turns partially transparent image pixels black

  - by Sean O'Hollaren

  I'm very new to C# and I've run into a problem and haven't been able to solve it. I have a row of buttons that have .png images assigned to them. The images are in .png format to allow transparency, and smoothing the edges in GIMP leaves some semi-transparent pixels. I've set the Image List Toolbar (imglToolbar)'s properties to recognize "Transparent" as the designated color to show up as transparent. I'm working in Visual Studio 2005. The strange thing is that everything looks great when I'm viewing the Visual C# form preview window. The icons look exactly as they should. However, once I actually build the project, the buttons treat every semi-transparent pixel near the edge of the image as if it's black. It seems like it can't handle one that's both transparent and has color. Image of it via the Visual C# form editor: Image of what it looks like when built: Any ideas as to why this is happening?

• How can you setup multiple WSGI apps on one server?

  - by Shakakai

  I'm working on a python based server product where a user can install WSGI-based python apps on their server. I can enforce any restriction on the application structure or format to make this easy. The user workflow would be: browse an app market, showing a list of WSGIpython apps select an app and choose "install" the app would be downloaded from a remote server to the user's server the http server would then have to be configured to start serving that application from the app's id, ex. a blog app with an id of "blog" at "/blog/", so all requests below /blog/ would be seen as root by the blog application. Any suggestions on how to set something like this up? Holler if my flow of consciousness lost you ;)

• Using Public/Private keys in reverse

  - by Wizzarding

  Hi, I have a situation where I need to make some data available for reading by anyone from a specific device, where the data is pre-loaded on the device, but I cannot allow anyone to create their own device and populate it with their own data in the same format. I know this sounds a little crazy, but there is a good reason! I was planning to use Public Key cryptography, encrypting the data with a public key, but then publishing the private key to anyone who wants to read the data. However, after looking at the RSACryptoServiceProvider and how it works it looks like I cannot just publish the private key as the private key can be used to create the public key. Could someone confirm that suspicion, or give me some hints on how I might be able to make this work! Many Thanks.

• Line by line image swing

  - by user1046017

  I want to show an image as it is downloading, I have the URL, and I am trying to get the image parts like this: InputStream openStream = url.openStream(); DataInputStream dis = new DataInputStream(new BufferedInputStream(openStream)); ByteArrayOutputStream os = new ByteArrayOutputStream(); while ((s = dis.read(b)) != -1) { os.write(b , 0, s); support.firePropertyChange("stream", null, os); } This way, any listener get the stream and creates an image, this way: if("stream".equals(evt.getPropertyName())){ try { ByteArrayOutputStream stream = (ByteArrayOutputStream) evt.getNewValue(); byte[] byteArray = stream.toByteArray(); stream.flush(); Image createImage = Toolkit.getDefaultToolkit().createImage(byteArray); this.getContentPane().add(new JLabel(new ImageIcon(createImage))); } catch (IOException ex) { Logger.getLogger(ImageTest.class.getName()).log(Level.SEVERE, null, ex); } } However, I am getting a "Premature end of JPEG file sun.awt.image.ImageFormatException: JPEG datastream contains no image" error, the image is a JPG image format, is there any library or method known to make something similar?

• k-means clustering in R on very large, sparse matrix?

  - by movingabout

  Hello, I am trying to do some k-means clustering on a very large matrix. The matrix is approximately 500000 rows x 4000 cols yet very sparse (only a couple of "1" values per row). The whole thing does not fit into memory, so I converted it into a sparse ARFF file. But R obviously can't read the sparse ARFF file format. I also have the data as a plain CSV file. Is there any package available in R for loading such sparse matrices efficiently? I'd then use the regular k-means algorithm from the cluster package to proceed. Many thanks

• C# Count registry keys existing using a partial value

  - by cheeseman

  Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing"); Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point"); I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it. Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword. At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient. for (int i = 0; i <= highestEntryPointValue; i++) { Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i)); if (entryKey != null) { count++; } }

• How to convert "9:00 PM EST" to a Date object

  - by Bara

  I am developing an Android application and require some basic datetime manipulation. I have a Date object (from Java.util.Date) holding a specific date. I need to add a specific time to it. The time I have is a string in this format: "9:00 PM EST" How would I "add" this time to the previous date? If the Date object currently has: "4/24/10 00:00:00" How would I change it to instead be: "4/24/10 09:00:00 EST" I would prefer to do this without the use of an external library, if possible.

• Get client timezone (not GMT offset amount) in JS

  - by Rex M

  I need to determine the client timezone (e.g. CET, GMT, EST) in JS. Getting the offset is straightforward, but doesn't have all the info necessary to determine the TZ, at least not easily. I have a feeling it might be possible to use a combination of offset, whether DST is in use and in effect, etc. but I'm hoping someone else has done the work already, especially considering the weird exceptions when dealing with time. This question is similar but both the question and the answer are based on the (incorrect) assumption every browser's DateString format includes the name of the timezone - which it does not. That is an implementation detail. So, with that I am currently stuck.

• jQuery selector after dynamically created element

  - by Bryan Williams

  I am trying to get an dynamically created element using a jQuery selector but it is returning an empty array. The first thing I am doing is grabbing an empty div: var packDiv = document.getElementById('templates'); packDiv.innerHTML = ""; then adding items to it in a loop: packDiv.innerHTML = packDiv.innerHTML + "<img id='" + thumbName + "' src='thumbs/" + thumbName + "'/>"; after the loop finishes I try to select an item using: console.log($("#"+thumbName)); and it returns the empty array. All the things I search on show to use .on but all the examples show that is to set event handlers. My question is how do I format a selector for dynamically created elements?

• Escaping and unescaping a string with single and double quotes in Javascript

  - by Reina

  I have a search box that a user can search for any string including single AND double quotes, once they have searched, the backend is passing the keyword back to me so I can put it back in the box. I don't know what the string is so I can't escape quotes myself, below is an example: var keyword = "hello"; $("#selectionkeywords").val(); The issue I am having is that if the user enters "hello" the keyword becomes ""hello"" and I get this error: missing ) after argument list [Break On This Error] jQuery("#selectionkeywords").val(""hello""); The user could also enter single quotes so that rules it out as well. I tried using escape unescape but I still have the same issue e.g. escape(""hello"") I could get the value in an unescaped format e.g. "hello" but I don't know what to do with it, escape doesn't work on it I end up with this %26%23034%3Bhello%26%23034%3B So I'm pretty much stuck at the moment as I can't do anything to the string, any ideas?

• Parsing plain data with Javascript (JQuery)

  - by Angelus

  Well , I have this text in a Javascript Var: GIMP Palette Name: Named Colors Columns: 16 # 255 250 250 snow (255 250 250) 248 248 255 ghost white (248 248 255) 245 245 245 white smoke (245 245 245) 220 220 220 gainsboro (220 220 220) 255 250 240 floral white (255 250 240) 253 245 230 old lace (253 245 230) 250 240 230 linen (250 240 230) 250 235 215 antique white (250 235 215) 255 239 213 papaya whip (255 239 213) And What I need is to cut it in lines and put them in one Array , after that i must separate each number and the rest in an string. I'm getting crazy searching functions to do that but now i can't see anyone in Javascript. modified End expected format will be first the next: array[0]='255 250 250 snow (255 250 250)' Then i wanna take it and extract each line into some vars to use them: colour[0]=255; colour[1]=250; colour[2]=250; string=snow (255 250 250); (the vars will be reused with each line)

• Force Decimal Regex

  - by babyangel86

  Hi, I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed. The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer. This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal. I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it. Any help would be much appreciated.

• Help with dates in Android

  - by SamRowley

  Hi guys, Looking for a bit of help with taking a dat from a DatePicker Widget and storing it in an sqlite database within the app. I have the following code: java.util.Date utilDate = null; String y = Integer.toString(date.getDayOfMonth()) + "/" + (date.getMonth()+1) + "/" + Integer.toString(date.getYear()); SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyy"); utilDate = formatter.parse(y); java.sql.Date z = new java.sql.Date(utilDate.getDate()); x = z.toString(); Log.v("The date: ", x); } Where date is the DatePicker widget. If I output the utilDate variable (i.e. the Java version of date) using logCat it seems to work fine and gives me a format like: Tue Jan 04 00:00:00 GMT 2011 which I am expecting but using the code above to get the sql version of the date, it always gives me the date 1970-01-01. I'm pretty sure the solution is very simple but I just can't see it.

• static images aren't caching with php-generated page

  - by scootklein

  Our website was just converted to being generated by mod_rewrite and php scripts. Images aren't caching in browsers when they seemingly should be. All images follow format: <img src="/images/header.png" /> I must avoid the script completely caching because the PHP parser needs to handle each page dynamically on each request; however, the download overhead of the large images is cumbersome on every single page load. I would ideally provide headers for "Cache-Control: no-cache, must-revalidate" and "Expires: some_date_in_the_past" to force revalidation of the PHP script. Why isn't the browser caching static images with consistent href values across all pages?

• How i store the images pixels in matrix form?

  Hi, I developing an application in which the pixelize image i want to be store in matrix format. The code is as follows. struct pixel { //unsigned char r, g, b,a; Byte r, g, b; int count; }; (NSInteger) processImage1: (UIImage*) image { // Allocate a buffer big enough to hold all the pixels struct pixel* pixels = (struct pixel*) calloc(1, image.size.width * image.size.height * sizeof(struct pixel)); if (pixels != nil) { // Create a new bitmap CGContextRef context = CGBitmapContextCreate( (void*) pixels, image.size.width, image.size.height, 8, image.size.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast ); NSLog(@"1=%d, 2=%d, 3=%d", CGImageGetBitsPerComponent(image), CGImageGetBitsPerPixel(image),CGImageGetBytesPerRow(image)); if (context != NULL) { // Draw the image in the bitmap CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, image.size.width, image.size.height), image.CGImage); NSUInteger numberOfPixels = image.size.width * image.size.height; I confusing about how to initialize the 2-D matrix in which the matrix store data of pixels.

• Sorting issues in flexigrid with "json" data

  - by John Sieber

  I'm currently using flexigrid to display data in a current project, but am running into issues with its ability to properly sort certain columns that contain dates or numbers. The data is being sent from a ColdFusion CFC that selects the appropriate data and then delivers it in the proper "json" format. As the date/time stamps and other fields containing numbers are sent as "strings" they do not sort properly in the data grid. Is this a limitation of Flexigrid or am I sending the data improperly to Flexigrid? I can provide examples of my code if that is helpful.

• Convert Military time to string representation

  - by RRUZ

  I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

• Developing a project which is an implementation of an open standard/protocol

  - by dotnetdev

  Hi, A lot of interesting code/projects are implementations of protocols, eg SNMP. How are projects like these, which depend on implementing a certain format, developed? Is the process something like get the guidelines of the protocol and then implement code which follows it. For example, XML-RPC is about transmitting XML docs between client/server, so the documentation on this protocol must outline the structure of the XML documents and then the way the transportation between client and server works, so the coder will implement this sort of functionality (xml doc construction, networking between the client and server). Projects I am thinking of (not to develop) are C# libraries which can interpret .PSDs, make VHDs, etc. So if I was to develop a C# app to implement .AI files (Illustrator files), what would be the steps I would look at (such as contacting Adobe, etc)? Is this the way such projects are developed?

• All things equal what is the fastest way to output data to disk in C++?

  - by user260197

  I am running simulation code that is largely bound by CPU speed. I am not interested in pushing data in/out to a user interface, simply saving it to disk as it is computed. What would be the fastest solution that would reduce overhead? iostreams? printf? I have previously read that printf is faster. Will this depend on my code and is it impossible to get an answer without profiling? Edit: Output data needs to be in text format, whether tab or comma separated. This will require formatting, precision, etc. Running in Windows.

• Axis xsd:dateTime issue

  - by milostrivun

  Here is the whole thing. I 'm using a webservice, with wsdl2java I generate classes and communicate with another application. Problem is , when I use a method from my generated WS client that is resulting in data that contains some object with data in format xsd:dateTime(Axis 1.4), and that data is represensted by java.util.Calendar object in java has time shifted to GMT(about two hours before my time zone). That results in bad data that I have to substract two hours to display correct value. My question is, considering I didn't work on building that webservice(all I have is wsdl url) where is the problem and can I fix it or the problem is at the side of the webservice creator. If I'm it is not clear what I am asking I will gladly explain as much as I can.
