  • How to iterate JPA collections in Google App engine

    - by palto
    Hi I use Google App Engine with datanucleus and JPA. I'm having a real hard time grasping how I'm supposed to read stuff from data store and pass it to JSP. If I load a list of POJOs with entitymanager and pass it to JSP, it crashes to org.datanucleus.exceptions.NucleusUserException: Object Manager has been closed. I understand why this is happening. Obviously because I fetch the list, close the entity manager and pass it to JSP, at which point it will fail because the list is lazy. How do I make the list NOT lazy without resorting to hacks like calling size() or something like that? Here is what I'm trying to do: @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { req.setAttribute("parties", getParties()); RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/parties.jsp"); dispatcher.forward(req, resp); } private List<Party> getParties(){ EntityManager em = entityManagerProvider.get(); try{ Query query = em.createQuery("SELECT p FROM Party p"); return query.getResultList(); }finally{ em.close(); } }

  • How to write to a text file in pipe delimited format from SQL Server / ASP.Net?

    - by NJTechGuy
    I have a text file which needs to be constantly updated (regular intervals). All I want is the syntax and possibly some code that outputs data from a SQL Server database using ASP.Net. The code I have so far is : <%@ Import Namespace="System.IO" %> <script language="vb" runat="server"> sub Page_Load(sender as Object, e as EventArgs) Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter ' If Len(Dir$(FILENAME)) > 0 Then Kill(FILENAME) objStreamWriter = File.AppendText(FILENAME) objStreamWriter.WriteLine("A user viewed this demo at: " & DateTime.Now.ToString()) objStreamWriter.Close() Dim objStreamReader as StreamReader objStreamReader = File.OpenText(FILENAME) Dim contents as String = objStreamReader.ReadToEnd() lblNicerOutput.Text = contents.Replace(vbCrLf, "<br>") objStreamReader.Close() end sub </script> <asp:label runat="server" id="lblNicerOutput" Font-Name="Verdana" /> With PHP, it is a breeze, but with .Net I have no clue. If you could help me with the database connectivity and how to write the data in pipe delimited format to an Output.txt file, that had be awesome. Thanks guys!

  • Appending an existing XML file with c#

    - by Farstucker
    I have an existing XML file that I would like to append without changing the format. Existing File looks like this: <Clients> <User username="farstucker"> <UserID>1</UserID> <DOB /> <FirstName>Steve</FirstName> <LastName>Lawrence</LastName> <Location>NYC</Location> </User> </Clients> How can I add another user using this format? My existing code is: string fileLocation = "clients.xml"; XmlTextWriter writer; if (!File.Exists(fileLocation)) { writer = new XmlTextWriter(fileLocation, null); writer.WriteStartDocument(); // Write the Root Element writer.WriteStartElement("Clients"); // End Element and Close writer.WriteEndElement(); writer.Close(); } // Append new data here Ive thought about using XmlDocument Fragment to append the data but Im not certain if I can maintain the existing format ( and empty tags ) without messing up the file. Any advice you could give is much appreciated. EDIT Ive changed the code to read the original XML but the file keeps getting overwritten.

  • Cross-Origin Resource Sharing (CORS) - am I missing something here?

    - by David Semeria
    I was reading about CORS (https://developer.mozilla.org/en/HTTP_access_control) and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going to authenticate the request. Hence, again if I'm not missing something, CORS actually makes it easier to steal sensitive information. I think it would have made much more sense if the original site could also supply an immutable list of servers its page is allowed to access. So the expanded sequence would be: 1) Supply a page with list of acceptable CORS servers (abc.com, xyz.com, etc) 2) Page wants to make an XHR request to abc.com - the browser allows this because it's in the allowed list and authentication proceeds as normal 3) Page wants to make an XHR request to malicious.com - request rejected locally (ie by the browser) because the server is not in the list. I know that malicious code could still use JSONP to do its dirty work, but I would have thought that a complete implementation of CORS would imply the closing of the script tag multi-site loophole. I also checked out the official CORS spec (http://www.w3.org/TR/cors) and could not find any mention of this issue.

  • problem with kCFSocketReadCallBack

    - by zp26
    Hello. I have a problem with my program. I created a socket with "kCFSocketReadCallBack. My intention was to call the "acceptCallback" only when it receives a string to the socket. Instead my program does not just accept the connection always goes into "startReceive" stop doing so and sometimes crash the program. Can anybody help? Thanks readSocket = CFSocketCreateWithNative( NULL, fd, kCFSocketReadCallBack, AcceptCallback, &context ); static void AcceptCallback(CFSocketRef s, CFSocketCallBackType type, CFDataRef address, const void *data, void *info) // Called by CFSocket when someone connects to our listening socket. // This implementation just bounces the request up to Objective-C. { ServerVistaController * obj; #pragma unused(address) // assert(address == NULL); assert(data != NULL); obj = (ServerVistaController *) info; assert(obj != nil); #pragma unused(s) assert(s == obj->listeningSocket); if (type & kCFSocketAcceptCallBack){ [obj acceptConnection:*(int *)data]; } if (type & kCFSocketAcceptCallBack){ [obj startReceive:*(int *)data]; } } -(void)startReceive:(int)fd { CFReadStreamRef readStream = NULL; CFIndex bytes; UInt8 buffer[MAXLENGTH]; CFStreamCreatePairWithSocket( kCFAllocatorDefault, fd, &readStream, NULL); if(!readStream){ close(fd); [self updateLabel:@"No readStream"]; } CFReadStreamOpen(readStream); [self updateLabel:@"OpenStream"]; bytes = CFReadStreamRead( readStream, buffer, sizeof(buffer)); if (bytes < 0) { [self updateLabel:(NSString*)buffer]; close(fd); } CFReadStreamClose(readStream); }

  • Incorrect syntax inserting data into table

    - by SelectDistinct
    I am having some trouble with my update() method. The idea is that the user Provides a recipe name, ingredients, instructions and then selects an image using Filestream. Once the user clicks 'Add Recipe' this will call the update method, however as things stand I am getting an error which is mentioning the contents of the text box: Here is the update() method code: private void updatedata() { // filesteam object to read the image // full length of image to a byte array try { // try to see if the image has a valid path if (imagename != "") { FileStream fs; fs = new FileStream(@imagename, FileMode.Open, FileAccess.Read); // a byte array to read the image byte[] picbyte = new byte[fs.Length]; fs.Read(picbyte, 0, System.Convert.ToInt32(fs.Length)); fs.Close(); //open the database using odp.net and insert the lines string connstr = @"Server=mypcname\SQLEXPRESS;Database=RecipeOrganiser;Trusted_Connection=True"; SqlConnection conn = new SqlConnection(connstr); conn.Open(); string query; query = "insert into Recipes(RecipeName,RecipeImage,RecipeIngredients,RecipeInstructions) values (" + textBox1.Text + "," + " @pic" + "," + textBox2.Text + "," + textBox3.Text + ")"; SqlParameter picparameter = new SqlParameter(); picparameter.SqlDbType = SqlDbType.Image; picparameter.ParameterName = "pic"; picparameter.Value = picbyte; SqlCommand cmd = new SqlCommand(query, conn); cmd.Parameters.Add(picparameter); cmd.ExecuteNonQuery(); MessageBox.Show("Image successfully saved"); cmd.Dispose(); conn.Close(); conn.Dispose(); Connection(); } } catch (Exception ex) { MessageBox.Show(ex.Message); } } Can anyone see where I have gone wrong with the insert into Recipes query or suggest an alternative approach to this part of the code?

  • CSS3PIE issues in IE6 and 8

    - by Gordon
    I'm using CSS3PIE to apply some rounded corners to elements in Internet Explorer that will get them by stylesheet in other browsers. I've run into some issues with it though. In IE8, I discovered that any element that had the PIE behaviour would behave strangely. The container would jump a few pixels to the right, but the content would stay in its original position, giving the appearance that the content had all shifted left relative to its container. This would be especially problematic on elements with no or small amounts of padding. I was able to hack my way around the problem in IE8 by using X-UA-Compatible, but I'd rather avoid this solution if at all possible. I don't have access to IE9 for testing but my understanding hacks like PIE aren't necessary and it would be wasteful to force a compatibility mode in a browser that doesn't need it. I have worse issues in IE6, with the PIE layout breaking down completely on a list that is set up to use display:inline; zoom:1; list items (to simulate inline-block, which works in IE8 and the other browsers). Here the borders of the list items get rendered in completely the wrong place. So ideally, I'd like to have PIE work properly in IE6, and in IE8 without having to resort to compatibility mode. As far as IE6 goes, a graceful fallback where PIE is just not applied will do. IE7 is the only browser where the page displays as intended. I can't provide an example page just at the moment unfortunately, I can add one later though. Follow up: Here are some screen grabs made with IE Tester. I'm hoping they will make things a little more clear for everybody. As you can see, IE7 is fine. However, in IE8, the containers are offset to the left relative to their content, and in IE6 the list elements (with the rounded 1 pixel border) are a complete mess! Full size versions for IE8, IE7 and IE6 are also available

  • How to find whole graph coverage path in dynamic state-flow diagram?

    - by joseph
    Hello, As I've been researching algorithms for path finding in graph, I found interesting problem. Definition of situation: 1)State diagram can have p states, and s Boolean Fields, and z Int Fields 2)Every state can have q ingoing and r outgoing transitions, and h Int fields (h belongs to z - see above) 3)Every transition can have only 1 event, and only 1 action 4)every action can change n Boolean Fields, and x Int Fields 5)every event can have one trigger from combination of any count of Boolean Fields in diagram 6)Transition can be in OPEN/CLOSED form. If the transition is open/closed depends on trigger2 compounded from 0..c Boolean fields. 7) I KNOW algorithm for finding shortest paths from state A to state B. 8) I KNOW algorithm for finding path that covers all states and transitions of whole state diagram, if all transitions are OPEN. Now, what is the goal: I need to find shortest path that covers all states and transitions in dynamically changing state diagram described above. When an action changes some int field, the algorithm should go through all states that have changed int field. The algorithm should also be able to open and close transition (by going through transitions that open and close another transitions by action) in the way that the founded path will be shortest and covers all transitions and states. Any idea how to solve it? I will be really pleased for ANY idea. Thanks for answers.

  • How can I embed images within my application and use them in HTML control?

    - by Atara
    Is there any way I can embed the images within my exe (as resource?) and use it in generated HTML ? Here are the requirements: A. I want to show dynamic HTML content (e.g. using webBrowser control, VS 2008, VB .Net, winForm desktop application) B. I want to generate the HTML on-the-fly using XML and XSL (file1.xml or file2.xml transformed by my.xsl) C. The HTML may contain IMG tags (file1.gif and or file2.gif according to the xml+xsl transformation) and here comes the complicated one: D. All these files (file1.xml, file2.xml, my.xsl, file1.gif, file2.gif) should be embedded in one exe file. I guess the XML and XSL can be embedded resources, and I can read them as stream, but what ways do I have to reference the image within the HTML ? <IMG src="???" /> I do not want to use absolute path and external files. If the image files are resources, can I use relative path? Relative to what? (I can use BASE tag, and then what?) Can I use stream as in email messages? If so, where can I find the format I need to use? http://www.websiteoptimization.com/speed/tweak/inline-images/ are browser dependent. What is the browser used by webBrowser control? IE? what version? Does it matter if I use GIF or JPG or BMP (or any other image format) for the images? Does it matter if I use mshtml library and not the regular webBrowser control? (currently I use http://www.itwriting.com/htmleditor/index.php ) Does it matter if I upgrade to VS 2010 ? Thanks, Atara

  • Replace without the replace function

    - by Molly Potter
    Assignment: Let X and Y be two words. Find/Replace is a common word processing operation that finds each occurrence of word X and replaces it with word Y in a given document. Your task is to write a program that performs the Find/Replace operation. Your program will prompt the user for the word to be replaced (X), then the substitute word (Y ). Assume that the input document is named input.txt. You must write the result of this Find/Replace operation to a file named output.txt. Lastly, you cannot use the replace() string function built into Python (it would make the assignment much too easy). To test your code, you should modify input.txt using a text editor such as Notepad or IDLE to contain different lines of text. Again, the output of your code must look exactly like the sample output. This is my code: input_data = open('input.txt','r') #this opens the file to read it. output_data = open('output.txt','w') #this opens a file to write to. userStr= (raw_input('Enter the word to be replaced:')) #this prompts the user for a word userReplace =(raw_input('What should I replace all occurences of ' + userStr + ' with?')) #this prompts the user for the replacement word for line in input_data: words = line.split() if userStr in words: output_data.write(line + userReplace) else: output_data.write(line) print 'All occurences of '+userStr+' in input.txt have been replaced by '+userReplace+' in output.txt' #this tells the user that we have replaced the words they gave us input_data.close() #this closes the documents we opened before output_data.close() It won't replace anything in the output file. Help!

  • Efficient database access when dealing with multiple abstracted repositories

    - by Nathan Ridley
    I want to know how most people are dealing with the repository pattern when it involves hitting the same database multiple times (sometimes transactionally) and trying to do so efficiently while maintaining database agnosticism and using multiple repositories together. Let's say we have repositories for three different entities; Widget, Thing and Whatsit. Each repository is abstracted via a base interface as per normal decoupling design processes. The base interfaces would then be IWidgetRepository, IThingRepository and IWhatsitRepository. Now we have our business layer or equivalent (whatever you want to call it). In this layer we have classes that access the various repositories. Often the methods in these classes need to do batch/combined operations where multiple repositories are involved. Sometimes one method may make use of another method internally, while that method can still be called independently. What about, in this scenario, when the operation needs to be transactional? Example: class Bob { private IWidgetRepository _widgetRepo; private IThingRepository _thingRepo; private IWhatsitRepository _whatsitRepo; public Bob(IWidgetRepository widgetRepo, IThingRepository thingRepo, IWhatsitRepository whatsitRepo) { _widgetRepo = widgetRepo; _thingRepo= thingRepo; _whatsitRepo= whatsitRepo; } public void DoStuff() { _widgetRepo.StoreSomeStuff(); _thingRepo.ReadSomeStuff(); _whatsitRepo.SaveSomething(); } public void DoOtherThing() { _widgetRepo.UpdateSomething(); DoStuff(); } } How do I keep my access to that database efficient and not have a constant stream of open-close-open-close on connections and inadvertent invocation of MSDTS and whatnot? If my database is something like SQLite, standard mechanisms like creating nested transactions are going to inherently fail, yet the business layer should not have to be concerning itself with such things. How do you handle such issues? Does ADO.Net provide simple mechanisms to handle this or do most people end up wrapping their own custom bits of code around ADO.Net to solve these types of problems?

  • PHP: problem rendering large images (error 321)

    - by JP19
    Hi ... its me again with a php problem :) Following is part of my PHP script which is rendering JPEG images. ... $tf=$requested_file; $image_type="jpeg"; header("Content-type: image/${image_type}"); $CMD="\$image=imagecreatefrom${image_type}('$tf'); image${image_type}(\$image);"; eval($CMD); exit; ... There is no syntactical error, because above code is working fine for small images, but for large images, it gives: Error 321 (net::ERR_INVALID_CHUNKED_ENCODING): Unknown error. in the browser. To be sure, I created two images using imagemagick from same source image - one resized to 10% of original and other 90%. http://mostpopularsports.net/images/misc/ttt10.jpg works http://mostpopularsports.net/images/misc/ttt90.jpg gives Error 301 in the browser. There is a related question with solution posted by OP here Error writing content through Apache. but I cannot understand how to make the fix. Can someome help me with it? I have looked at the headers in Chrome. For the first request, everything is fine. For the second request - the request headers are all garbled. Both images are jpeg (as they are created from imagemagick. But still to be sure I checked): misc/ttt10.jpg: JPEG image data, JFIF standard 1.01 misc/ttt90.jpg: JPEG image data, JFIF standard 1.01 Finally, the way I fixed is, remove the Transfer-Encoding: chunked header from the response. [This header was sent by apache only when the data was large enough]. (I had an internal proxy, so did it in the proxy script - otherwise one may need to do it in apache settings). There were some good answers and I have selected the one that helped me solve the problem best. thanks JP

  • mvc jquery passing form values after user presses "Accept" button

    So I have a form and a submit button that posts the form to an action. But I wanted to show a popup where the user can deny or accept an agreement. Here's my jquery $(document).ready((function () { var dialog = $('#confirmation-dialog').dialog({ autoOpen: false, width: 500, height: 600, resizable: false, modal: true, buttons: { "Accept": function () { $(this).dialog('close'); $.ajax({ type: 'POST', data: {__RequestVerificationToken: $("input[name=__RequestVerificationToken]").val()} }); }, "Cancel": function () { $(this).dialog('close'); } } }); $('#registration-submit').click(function (e) { var action = $(this.form); console.log(action); var form = $('form'); dialog.dialog("open"); return false; }); })); My problem with this is that it would post, but it would only send my AntiforgeryToken, and not the values of the form. But when it goes through the TryupdateModel it would go through for some reason but will not Save (cuz of the missing data that wasn't passed on the formcollection).

  • Images in IFRAME no longer showing after I log out of Flickr?

    - by contact-kram
    I have a iframe window which displays user's flickr images. I use the flickr.photos.search api to download the user's image from flickr. This works great when the user is logged into flickr. But when I explicitly log off the user from flickr and the yahoo network and then attempt to download the flickr images, I get redirected to www.yahoo.com in a full browser window (not in my iframe). If I remember correctly, I did not have this issue when I was not using iframes and I was being redirected to the yahoo login screen. Any suggestions? To elaborate, this URI - http://www.flickr.com/services/api/auth.howto.web.html, lists the below step - Create an auth handler When users follow your login url, they are directed to a page on flickr.com which asks them if they want to authorize your application. This page displays your application title and description along with the logo, if you uploaded one. When the user accepts the request, they are sent back to the Callback URL you defined in step 2. The URL will have a frob parameter added to it. For example, if your Callback URL was http://test.com/auth.php then the user might be redirected to http://test.com/auth.php?frob=185-837403740 (The frob value in this example is '185-837403740'). This does not happen when I am in my iframe window but it does happen in my full browser window.

  • Programmatically parse and edit C++ Source Files

    - by Kryten
    Hi, I want to able programmatically parse and edit C++ source files. I need to be able to change/add code in certain sections of code (i.e. in functions, class blocks, etc). I would also (preferably) be able to get comments as well. Part of what I want to do can be explained by the following piece of code: CPlusPlusSourceParser cp = new CPlusPlusSourceParser(“x.cpp”); // Create C++ Source Parser Object CPlusPlusSourceFunction[] funcs = cp.getFunctions(); // Get all the functions for (int i = 0; i &lt funcs.length; i++) { // Loop through all functions funcs[i].append(/* … code I want to append …*/); // Append some code to function } cp.save(); // Save new source cp.close(); // Close file How can I do that? I’d like to be able to do this preferably in Java, C++, Perl, Python or C#. However, I am open to other language API’s.

  • Line End Problem Reading with Scanner Class in Java

    I am not an experienced Java programmer and i'm trying to write some text to a file and then read it with Scanner. I know there are lots of ways of doing this, but i want to write records to file with delimiters, then read the pieces. The problem is so small. When I look the output some printing isn't seen(shown in below). I mean the bold line in the Output that is only written "Scanner". I would be appreciated if anyone can answer why "String: " isn't seen there. (Please answer just what i ask) I couldn't understand if it is a simple printing problem or a line end problem with "\r\n". Here is the code and output: import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.util.Scanner; public class Tmp { public static void main(String args[]) throws IOException { int i; boolean b; String str; FileWriter fout = new FileWriter("test.txt"); fout.write("Testing|10|true|two|false\r\n"); fout.write("Scanner|12|one|true|"); fout.close(); FileReader fin = new FileReader("Test.txt"); Scanner src = new Scanner(fin).useDelimiter("[|\\*]"); while (src.hasNext()) { if (src.hasNextInt()) { i = src.nextInt(); System.out.println("int: " + i); } else if (src.hasNextBoolean()) { b = src.nextBoolean(); System.out.println("boolean: " + b); } else { str = src.next(); System.out.println("String: " + str); } } fin.close(); } } Here is the output: String: Testing int: 10 boolean: true String: two String: false Scanner int: 12 String: one boolean: true

  • How to validate DataReader is actually closed using FxCop custom rule?

    - by tanmay
    I have written couple of custom rules in for FxCop 1.36. I have written code to find weather an opened DataReader is closed or not. But it does not check which DataReader object is calling the Close() method so I can't be sure if all opened DataReader objects are closed!! 2nd: If I am a DataReader in an 'if/else' like if 1=2 dr = cmd.ExecuteReader(); else dr = cmd2.ExecuteReader(); end if In this case it will search for 2 DataReader objects to be closed. I am putting my code for more clarity. public override ProblemCollection Check(Member member) { Method method = member as Method; int countCatch =0; int countErrLog = 0; Instruction objInstr = null; if (method != null) { for (int i = 0; i < method.Instructions.Count; i++) { objInstr = method.Instructions[i]; if (objInstr.Value != null) { if (objInstr.Value.ToString() .Contains("System.Data.SqlClient.SqlDataReader")) { countCatch += 1; } if (countCatch>0) { if (objInstr.Value.ToString().Contains( "System.Data.SqlClient.SqlDataReader.Close")) { countErrLog += 1; } } } } } if (countErrLog!=countCatch) { Resolution resolu = GetResolution(new string[] { method.ToString() }); Problems.Add(new Problem(resolu)); } return Problems; }

  • PHP.ini Settings Are Ignored By PHP5.3.5 Running With Windows 7 And Apache 2.2.15

    - by Andy
    I did an install of PHP5.3.5 on Windows 7 Home Premium using the MSI installer download. I got it to overwrite a previous version of PHP5 in C:\php5\ When first testing it, the server failed to start. I fixed this by adding the path to PHP in the Apache2.2 httpd file where the installer had inserted 2 lines of coded pointing to the ini file directory and the PHP DLL but had left out the directory path. After doing this, the server starts ok and I can run phpinfo to view the PHP settings in my web browser on local host. In the phpinfo it states that the loaded configuration file is C:\php5\php.ini as expected. But if I make any changes to the settings, and reboot the server, none of the changes are reflected in phpinfo. Yes, I do refresh the browser window. If I rename the php.ini to something else to make it invisible phpinfo then correctly identifies that there is no php.ini file loaded. So the settings in php.ini are being ignored and some default settings are being used (but I have no idea where these are derived from). As far as I can tell, there are no other php.ini files on my computer. In phpinfo it states that the Configuration File (php.ini) Path is C:\Windows but this is the same as on a Windows XP computer that I work on. And in the windows folder I don't see any php.ini file. In the windows registry, there is no mention of PHP5, and the PATH environment variable starts with C:\php5\; So hopefully someone can suggest how I can get PHP5 to take notice of the C:\php5\php.ini settings. :)

    I have a text file which needs to be constantly updated (regular intervals). All I want is the syntax and possibly some code that outputs data from a MS Sql Database using ASP.Net. The code I have so far is : <%@ Import Namespace="System.IO" %> <script language="vb" runat="server"> sub Page_Load(sender as Object, e as EventArgs) Dim FILENAME as String = Server.MapPath("Output.txt") Dim objStreamWriter as StreamWriter ' If Len(Dir$(FILENAME)) > 0 Then Kill(FILENAME) objStreamWriter = File.AppendText(FILENAME) objStreamWriter.WriteLine("A user viewed this demo at: " & DateTime.Now.ToString()) objStreamWriter.Close() Dim objStreamReader as StreamReader objStreamReader = File.OpenText(FILENAME) Dim contents as String = objStreamReader.ReadToEnd() lblNicerOutput.Text = contents.Replace(vbCrLf, "<br>") objStreamReader.Close() end sub </script> <asp:label runat="server" id="lblNicerOutput" Font-Name="Verdana" /> With PHP, it is a breeze, but with .Net I have no clue. If you could help me with the database connectivity and how to write the data in pipe delimited format to an Output.txt file, that had be awesome. Thanks guys!

  • Div's visibility with javascript - problem

    - by sammville
    I am trying to use div's to display content on my page. This is controlled with an onchange element in a select menu. It works perfectly but the problem is I want one div to close when another one is opened. The div's open fine but it does not close the others. An example code is below. What am I doing wrong? JavaScript: if(document.getElementById('catgry').value == '01'){ document.getElementById('post04').style.visibility = "visible"; document.getElementById('post04').style.display = ""; document.getElementById('post07').style.visibility = "hidden"; document.getElementById('post07').style.display = "none"; }else if(document.getElementById('catgry').value == '02'){ document.getElementById('post02').style.visibility = "visible"; document.getElementById('post02').style.display = ""; document.getElementById('post04').style.visibility = "hidden"; document.getElementById('post04').style.display = "none"; document.getElementById('post07').style.visibility = "hidden"; document.getElementById('post07').style.display = "none"; } HTML: <div id="post04" style="visibility:hidden; display:none;"> <table class="posttb"><tr> <td width="30%">Author</td> <td><input type="text" name="author" size="30" class="postfd"></td> </tr> </table> </div>

  • Auto Submitting a form (cURL)

    - by cast01
    Im writing a form to post data off to paypal, and this works fine, i create the form with hidden fields and then have a submit button that submits everything to paypal. However, when the user clicks that button, there is more that i want to do, for example change their cart status in the database. So, i want to be able to execute some code when they click submit and then post the data to paypal. I dont want to use javascript for this. My method at the moment is using cURL, the form posts back to the current page, i then check for $_POST data, do my other commands like updating the status of the cart, and then create a curl command, and post the form data to paypal. Now, it gets posted successfully, but the browser doesnt go off to paypal. At first i was just retirieving the result in a string and then echoing it out and i could see that the post was successful, then i set CURLOPT_FOLLOWLOCATION to 1 assuming this would let the browser go off to paypal but it doesnt, what it seems to do is grab some stuff from paypal and put it on my page. Is using cURL the right thing for this? and if so, how do i get round this problem? I want to stay away from javascript for this as only users with javascript enabled would have their cart updated. The code im using for curl is below, the post_data is an array i created and then read key-value pairs into post_string. //Set cURL Options curl_setopt($curl_connection, CURLOPT_CONNECTTIMEOUT, 30); curl_setopt($curl_connection, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"); curl_setopt($curl_connection, CURLOPT_RETURNTRANSFER, false); curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl_connection, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl_connection, CURLOPT_MAXREDIRS, 20); //Set Data to be Posted curl_setopt($curl_connection, CURLOPT_POSTFIELDS, $post_string); //Execute Request curl_exec($curl_connection);

  • How do I set the LRECL in C#.NET?

    - by donde
    I have been trying to ftp a dtl file from .net to, what I beleive, is an AS400. The error being reported back to me is: "One or more lines have been truncated" and the admin is saying the file is coming over with 256 lines that have variable length columns. I found this explanation online: we have to establish defaults because no specifics about the file exist. The default RECFM is V and LRECL is 256. This means that SAS will scan the input record looking for the CR & LF to tell us that we are at the EOR. If the marker isn't found within the limit of the LRECL, SAS discards the data from the LRECL value to the end of the record and adds a message to the Log that "One or more lines have been truncated". So I need to set the LRECL. How do I do this in C# .NET? FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath); ftp.Credentials = new NetworkCredential(user, pwd); ftp.KeepAlive = false; ftp.UseBinary = false; ftp.Method = WebRequestMethods.Ftp.UploadFile; FileStream fs = File.OpenRead(inputfilepath + ftpfileName); byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); fs.Close(); Stream ftpstream = ftp.GetRequestStream(); int i = 0; int intBlock = 1786; int intBuffLeft = buffer.Length; while (i < buffer.Length) { if (intBuffLeft >= 1786) { ftpstream.Write(buffer, i, intBlock); } else { ftpstream.Write(buffer, i, intBuffLeft); } i += intBlock; intBuffLeft -= 1786; } ftpstream.Close();
