  • Uploading an xml direct to ftp

    - by Joshua Maerten
    i put this direct below a button: XmlDocument doc = new XmlDocument(); XmlElement root = doc.CreateElement("Login"); XmlElement id = doc.CreateElement("id"); id.SetAttribute("userName", usernameTxb.Text); id.SetAttribute("passWord", passwordTxb.Text); XmlElement name = doc.CreateElement("Name"); name.InnerText = nameTxb.Text; XmlElement age = doc.CreateElement("Age"); age.InnerText = ageTxb.Text; XmlElement Country = doc.CreateElement("Country"); Country.InnerText = countryTxb.Text; id.AppendChild(name); id.AppendChild(age); id.AppendChild(Country); root.AppendChild(id); doc.AppendChild(root); // Get the object used to communicate with the server. FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://users.skynet.be"); request.Method = WebRequestMethods.Ftp.UploadFile; request.UsePassive = false; // This example assumes the FTP site uses anonymous logon. request.Credentials = new NetworkCredential("fa490002", "password"); // Copy the contents of the file to the request stream.

  • c programming malloc question

    - by user535256
    Hello guys, Just got query regarding c malloc() function. I am read()ing x number of bytes from a file to get lenght of filename, like ' read(file, &namelen, sizeof(unsigned char)); ' . The variable namelen is a type unsigned char and was written into file as that type (1 byte). Now namelen has the lenght of filename ie namelen=8 if file name was 'data.txt', plus extra /0 at end, that working fine. Now I have a structure recording file info, ie filename, filelenght, content size etc. struct fileinfo { char *name; ...... other variable like size etc }; struct fileinfo *files; Question: I want to make that files.name variable the size of namelen ie 8 so I can successfully write the filename into it, like ' files[i].name = malloc(namelen) ' However, I dont want it to be malloc(sizeof(namelen)) as that would make it file.name[1] as the size of its type unsigned char. I want it to be the value thats stored inside variable &namelen ie 8 so file.name[8] so data.txt can be read() from file as 8 bytes and written straight into file.name[8? Is there a way to do this my current code is this and returns 4 not 8 files[i].name = malloc(namelen); //strlen(files[i].name) - returns 4 //perhaps something like malloc(sizeof(&namelen)) but does not work Thanks for any suggestions Have tried suggested suggestions guys, but I now get a segmentation fault error using: printf("\nsizeofnamelen=%x\n",namelen); //gives 8 for data.txt files[i].name = malloc(namelen + 1); read(file, &files[i].name, namelen); int len=strlen(files[i].name); printf("\nnamelen=%d",len); printf("\nname=%s\n",files[i].name); When I try to open() file with that files[i].name variable it wont open so the data does not appear to be getting written inside the read() &files[i].name and strlen() causes segemntation error as well as trying to print the filename

  • My C# UploadFile method successfully uploads a file, but then my UI hangs...

    - by kyrathaba
    I have a simple WinForms test application in C#. Using the following method, I'm able to upload a file when I invoke the method from my button's Click event handler. The only problem is: my Windows Form "freezes". I can't close it using the Close button. I have to end execution from within the IDE (Visual C# 2010 Express edition). Here are the two methods: public void UploadFile(string FullPathFilename) { string filename = Path.GetFileName(FullPathFilename); try { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(_remoteHost + filename); request.Method = WebRequestMethods.Ftp.UploadFile; request.Credentials = new NetworkCredential(_remoteUser, _remotePass); StreamReader sourceStream = new StreamReader(FullPathFilename); byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); request.ContentLength = fileContents.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); FtpWebResponse response = (FtpWebResponse)request.GetResponse(); response.Close(); requestStream.Close(); sourceStream.Close(); } catch (Exception ex) { MessageBox.Show(ex.Message, "Upload error"); } finally { } } which gets called here: private void btnUploadTxtFile_Click(object sender, EventArgs e) { string username = "my_username"; string password = "my_password"; string host = "ftp://mywebsite.com"; try { clsFTPclient client = new clsFTPclient(host + "/httpdocs/non_church/", username, password); client.UploadFile(Path.GetDirectoryName(Application.ExecutablePath) + "\\myTextFile.txt"); } catch (Exception ex) { MessageBox.Show(ex.Message, "Upload problem"); } }

  • grailsApplication access in Grails unit Test

  • Dynamic vertical menu for Wordpress

    - by buttonstack
    Does anyone know how to achieve a dynamic multi-level page menu for Wordpress? I have found a couple scripts but none of them put the subpages directly under the parent page or some will show every subpage to the entire menu Example: page1 (selected) –subpage1-1 –subpage1-2 page2 page3 This code comes close by inserting the subpages directly under, but it doesn't hide the subpages to the other pages. <?php if($post->post_parent) { $children = preg_replace('@\<li([^>^]*)>\<a([^>^]*)>(.*?)\<\/a>@i','<li$1><a$2><span>$3</span></a>',wp_list_pages('title_li=&amp;amp;amp;amp;amp;child_of='.$post->post_parent.'&amp;amp;amp;amp;amp;echo=0&amp;amp;amp;amp;amp;depth=1')); } else { $children = preg_replace('@\<li([^>^]*)>\<a([^>^]*)>(.*?)\<\/a>@i','<li$1><a$2><span>$3</span></a>',wp_list_pages('title_li=&amp;amp;amp;amp;amp;child_of='.$post->ID.'&amp;amp;amp;amp;amp;echo=0&amp;amp;amp;amp;amp;depth=1')); } if($children) { echo" <ul class=\"submenu\">\n". $children ."</ul>\n"; } ?>

  • Ruby integer to string key

    - by Gene
    A system I'm building needs to convert non-negative Ruby integers into shortest-possible UTF-8 string values. The only requirement on the strings is that their lexicographic order be identical to the natural order on integers. What's the best Ruby way to do this? We can assume the integers are 32 bits and the sign bit is 0. This is successful: (i >> 24).chr + ((i >> 16) & 0xff).chr + ((i >> 8) & 0xff).chr + (i & 0xff).chr But it appears to be 1) garbage-intense and 2) ugly. I've also looked at pack solutions, but these don't seem portable due to byte order. FWIW, the application is Redis hash field names. Building keys may be a performance bottleneck, but probably not. This question is mostly about the "Ruby way".

  • SWT Problem with MouseTrackListener and Shell

    - by Krt_Malta
    Hi! I'm developing an Eclipse plug-in and I have a problem which is reproduced in this small SWT application: public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Text text = new Text(shell, SWT.MULTI | SWT.WRAP | SWT.READ_ONLY | SWT.V_SCROLL); text.setText("Hello"); shell.setLayout(new FillLayout()); shell.addMouseTrackListener(new MouseTrackListener() { public void mouseEnter(MouseEvent arg0) { System.out.println("mouseEnter"); } public void mouseExit(MouseEvent arg0) { System.out.println("mouseExit"); } public void mouseHover(MouseEvent arg0) { System.out.println("mouseHover"); } }); // Display the window shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) { display.sleep(); } } display.dispose(); } As you can see I'm creating a shell and putting a Textbox inside it and putting it all across the shell. Then I attach a MouseTrackListener to the shell. The events don't fire (as in when I hover in the shell "mouseHover" is not printed etc). When I remove the Textbox the events fire. Can anyone tell me where the problem lies please? I don't want to attach a listener to the textbox but to the shell. I'll really appreciate the help because I've been trying to trace it for quite some time now. Thanks and regards, Krt_Malta

  • Row Prefix - ItemsControl with UniformGrid

    - by tenfour
    I am using an ItemsControl to display a List<byte> in hex. The ItemsPanelTemplate is a UniformGrid with a fixed number of columns: <ItemsControl HorizontalAlignment="Left" VerticalAlignment="Top" ItemsSource="{Binding}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <UniformGrid Columns="16"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding StringFormat='\{0:X2\}'}" Margin="5,5,5,0"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I'd like to prefix each row with an 'Address' column, just like you'd see with the Notepad++ 'HEX-Editor' plugin. That is, since I have 16 columns, each row should be prefixed something like this: 0000 [00 01 02 .... 0F] 0010 [10 11 12 .... 1F] 0020 [20 21 22 .... 2F] ... Any suggestions?

  • XmlSerializer 'forgetting' my namespace

    - by Michel
    Hi, i have to create an XML file with all the elements prefixed, like this: <ps:Request num="123" xmlns:ps="www.ladieda.com"> <ps:ClientId>5566</ps:ClientId> <ps:Request> When i serialize my object, c# is smart and does this: <Request num="123" xmlns="www.ladieda.com"> <ClientId>5566</ClientId> <Request> That is good, because the ps: is not necessary. But is there a way to force C# to serialize all the prefixes? My serialize code is this (for incoming object pObject): String XmlizedString = null; MemoryStream memoryStream = new MemoryStream(); XmlSerializer xs = new XmlSerializer(pObject.GetType()); XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); xs.Serialize(xmlTextWriter, pObject); memoryStream = (MemoryStream)xmlTextWriter.BaseStream; XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray()); return XmlizedString; private String UTF8ByteArrayToString(Byte[] characters) { UTF8Encoding encoding = new UTF8Encoding(); String constructedString = encoding.GetString(characters); return (constructedString); }

  • How can I write an XML on my hard drive to GetRequestStream

    - by swolff1978
    I need to post raw xml to a site and read the response. With the following code I keep getting an "Unknown File Format" error and I'm not sure why. XmlDocument sampleRequest = new XmlDocument(); sampleRequest.Load(@"C:\SampleRequest.xml"); byte[] bytes = Encoding.UTF8.GetBytes(sampleRequest.ToString()); string uri = "https://www.sample-gateway.com/gw.aspx"; req = WebRequest.Create(uri); req.Method = "POST"; req.ContentLength = bytes.Length; req.ContentType = "text/xml"; using (var requestStream = req.GetRequestStream()) { requestStream.Write(bytes, 0, bytes.Length); } // Send the data to the webserver rsp = req.GetResponse(); XmlDocument responseXML = new XmlDocument(); using (var responseStream = rsp.GetResponseStream()) { responseXML.Load(responseStream); } I am fairly certain my issue is what/how I am writing to the requestStream so.. How can I modify that code so that I may write an xml located on the hard drive to the request stream?

  • Best solution for an StringToInt function in C#

    - by StefanE
    Hi, I were asked to do an StringToInt / Int.parse function on the white board in an job interview last week and did not perform very good but I came up with some sort of solution. Later when back home I made one in Visual Studion and I wonder if there are any better solution than mine below. Have not bothred with any more error handling except checking that the string only contains digits. private int StrToInt(string tmpString) { int tmpResult = 0; System.Text.Encoding ascii = System.Text.Encoding.ASCII; byte[] tmpByte = ascii.GetBytes(tmpString); for (int i = 0; i <= tmpString.Length-1; i++) { // Check whatever the Character is an valid digit if (tmpByte[i] > 47 && tmpByte[i] <= 58) // Here I'm using the lenght-1 of the string to set the power and multiply this to the value tmpResult += (tmpByte[i] - 48) * ((int)Math.Pow(10, (tmpString.Length-i)-1)); else throw new Exception("Non valid character in string"); } return tmpResult; }

  • Dealing with image upload on server

    - by user1073320
    I have got a the following problem: I have got multi-step form where in one step user upload image to server and then few steps further supplies other information, when this information is invalid no data should be commited - also the image should be deleted. I was thinking about PHP session, but I've read here PHP - Store Images in SESSION data? that it is inefficient way. Every time you proceed step in the form the image is reloaded (in the session) and as somebody mentioned "You will want it to only be as big as it needs to be and you need to delete it as soon as you don't need it because large pieces of information in the session will slow down the session startup." - here i got a question: will it slow down the stratup the session of user who upload file or sessions of all users? I have to mention that I'm looking for solution that doesn't rely on operating system scripts (cron or etc) - I have no permission to run such scripts. The perfect solution for me would be: saving image on disk (for example in some folder named after session id) then after the latest step of form move this image or delete depending on form validation. If user unexpectedly destroy the session (for example closing the browser) of course the folder with image should be deleted. In nutshell I need somethig like callback to event "destroying session".

  • Best suited tool to document message processing done in C written program

    - by user3494614
    I am relatively new to UML and it's seems to be very vast I have a small program which basically receives messages on socket and then depending upon message ID embedded as first byte of message it processes the buffer. There are around 5 different message ID which it processes and communicates on another socket and has around 8 major functions. So program in short is like this. I am not pasting entire .c file or main function but just giving some bits and pieces of it so that to get idea of program flow. int main(int argc, char** argv) { register_shared_mem(); listen(); while(get_next_message(buffer)) { switch((msg)(buffer)->id) { case TYPE1: process1(); answer(); ..... } } } I want to document this is pictorial way like for Message type 1 it calls this function which calls another and which calls another. Please let me know any open source tool which will allow me to quickly draw such kind of UML or sequence diagram and will also allow me to write brief description of what each function does? Thanks In Advance

  • Optimize SQL connection?

    - by user1484035
    I am building a multi-page web project in HTML and Javascript that is constantly reading from AND writing to an SQL database. I can connect to the database and successfully run my project with this type of connection. var connection = new ActiveXObject("ADODB.Connection") ; var connectionstring="Data Source=<server>;Initial Catalog=<catalog>;User ID=<user>; Password=<password>;Provider=SQLOLEDB"; connection.Open(connectionstring); var rs = new ActiveXObject("ADODB.Recordset"); rs.Open("SELECT * FROM table", connection); rs.MoveFirst while(!rs.eof) { document.write(rs.fields(1)); rs.movenext; } rs.close; connection.close; Works great and runs fine. BUT, the first 5 lines (from var connection = to var rs =) causes the whole browser to freeze for a few seconds while it establishes the connection. I need to speed that up since I am constantly connecting to the database throughout my project. Is there a more effective way of connecting to a SQL database? or is my computer just bad and this should run faster?

  • PHP Outputting File Attachments with Headers

I presume all other file types will be corrupt - have not even tried them Any ideas on what I am doing wrong? Thanks - UPDATE: changed line of code as suggested - still same issue.

  • Why does the output look like this?

    I have a c program below, I would like to send out a 32 bit message in a particular order Eg.0x00000001. #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <stdint.h> struct test { uint16_t a; uint16_t b; }; int main(int argc, char const *argv[]) { char buf[4]; struct test* ptr=(struct test*)buf; ptr->a=0x0000; ptr->b=0x0001; printf("%x %x\n",buf[0],buf[1]); //output is 0 0 printf("%x %x\n",buf[2],buf[3]); //output is 1 0 return 0; } Then I test it by print out the values in char array. I got output in the above comments. Shouldn't the output be 0 0 and 0 1? since but[3] is the last byte? Is there anything I missed? Thanks!

  • ecommerce platform or from scratch? customer specific catalogs and purchase orders

    - by rafi
    I have a possible freelance job in front of me for a distributor who wants product ordering set up but the orders are all P.O.s basically - no actual credit card or paypal transaction. The customer is simply billed and the order archived. Customers will need to login to this site and each customer will have their own custom catalog of a few dozen products which have been setup via a control panel this distributor uses. So there will be a master catalog of over 1,000 products (perhaps browsable but not to be ordered from on the site) but each customer will only be able to order from the products specified for their accounts. I know I can build this from scratch but I figured it's worth looking into what ecommerce platforms would get me a nice head start. Obviously shopping cart, order history, catalog management are concepts that I can reuse but are any of the ecommerce systems out there also capable of handling custom catalogs (maybe as multi-stores?) or transactions billed to accounts without credit card? The more I could reuse the better. I've messed with OSCommerce (way back) and a little Zen Cart more recently. I've also worked on a number of totally custom e-commerce sites. But my knowledge of the open source e-commerce tools is pretty limited and I'm trying to keep the effort as simple as I possibly can on this. I'm pretty flexible on the language of the platform by the way. Thanks in advance.

    Our application allows administrators to add “User Properties” in order for them to be able to tailor the system to match their own HR systems. For example, if your company has departments, you can define “Departments” in the Properties table and then add values that correspond to “Departments” such as “Jewelry”, “Electronics” etc… You are then able to assign a department to users. Here is the schema: In this schema, a User can have only one UserPropertyValue per Property, but doesn’t have to have a value for the property. I am trying to build a query that will be used in SSRS 2005 and also have it use the PropertyValues as the filter for users. My query looks like this: SELECT UserLogin, FirstName, LastName FROM Users U LEFT OUTER JOIN UserPropertyValues UPV ON U.ID = UPV.UserID WHERE UPV.PropertyValueID IN (1, 5) When I run this, if the user has ANY of the property values, they are returned. What I would like to have is where this query will return users that have values BY PROPERTY. So if PropertyValueID = 1 is of Department (Jewelry), and PropertyValueID = 5 is of EmploymentType (Full Time), I want to return all users that are in Department Jewelry that are EmployeeType of Full Time, can this be done? Here's a full data example: User A has Department(Jewelry value = 1) and EmploymentType(FullTime value = 5)User B has Department(Electronics value = 2) and EmploymentType(FullTime value = 5)User C has Department(Jewelry value = 1) and EmployementType(PartTime value = 6) My query should only return User A using the above query UPDATE: I should state that this query is used as a dataset in SSRS, so the parameter passed to the query will be @PropertyIDs and it is defined as a multi-value parameter in SSRS. WHERE UPV.PropertyValueID IN (@PropertyIDs)

  • Boost multi_index_container crash in release mode

    - by Zan Lynx
    I have a program that I just changed to using a boost::multi_index_container collection. After I did that and tested my code in debug mode, I was feeling pretty good about myself. However, then I compiled a release build with NDEBUG set, and the code crashed. Not immediately, but sometimes in single-threaded tests and often in multi-threaded tests. The segmentation faults happen deep inside boost insert and rotate functions related to the index updates and they are happening because a node has NULL left and right pointers. My code looks a bit like this: struct Implementation { typedef std::pair<uint32_t, uint32_t> update_pair_type; struct watch {}; struct update {}; typedef boost::multi_index_container< update_pair_type, boost::multi_index::indexed_by< boost::multi_index::ordered_unique< boost::multi_index::tag<watch>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::first> >, boost::multi_index::ordered_non_unique< boost::multi_index::tag<update>, boost::multi_index::member<update_pair_type, uint32_t, &update_pair_type::second> > > > update_map_type; typedef std::vector< update_pair_type > update_list_type; update_map_type update_map; update_map_type::iterator update_hint; void register_update(uint32_t watch, uint32_t update); void do_updates(uint32_t start, uint32_t end); }; void Implementation::register_update(uint32_t watch, uint32_t update) { update_pair_type new_pair( watch_offset, update_offset ); update_hint = update_map.insert(update_hint, new_pair); if( update_hint->second != update_offset ) { bool replaced _unused_ = update_map.replace(update_hint, new_pair); assert(replaced); } }

  • Why does the '#weight' property sometimes not have any effect in Drupal forms?

    - by Adrian
    Hello, I'm trying to create a node form for a custom type. I have organic groups and taxonomy both enabled, but want their elements to come out in a non-standard order. So I've implemented hook_form_alter and set the #weight property of the og_nodeapi subarray to -1000, but it still goes after taxonomy and menu. I even tried changing the subarray to a fieldset (to force it to actually be rendered), but no dice. I also tried setting $form['taxonomy']['#weight'] = 1000 (I have two vocabs so it's already being rendered as a fieldset) but that didn't work either. I set the weight of my module very high and confirmed in the system table that it is indeed the highest module on the site - so I'm all out of ideas. Any suggestions? Update: While I'm not exactly sure how, I did manage to get the taxonomy fieldset to sink below everything else, but now I have a related problem that's hopefully more manageable to understand. Within the taxonomy fieldset, I have two items (a tags and a multi-select), and I wanted to add some instructions in hook_form_alter as follows: $form['taxonomy']['instructions'] = array( '#value' => "These are the instructions", '#weight' => -1, ); You guessed it, this appears after the terms inserted by the taxonomy module. However, if I change this to a fieldset: $form['taxonomy']['instructions'] = array( '#type' => 'fieldset', // <-- here '#title' => 'Instructions', // <-- and here for good measure '#value' => "These are the instructions", '#weight' => -1, ); then it magically floats to the top as I'd intended. I also tried textarea (this also worked) and explicitly saying markup (this did not). So basically, changing the type from "markup" (the default IIRC) to "fieldset" has the effect of no longer ignoring its weight.

  • Software Company Library

    - by dbemerlin
    Hi. A few days ago i had the idea to create a company library since my company has no training and many developers still develop as they did when they learned it 5 years ago. My hope is that they can lend books, read them and hopefully learn something from them (for example: object oriented programming or unit testing, which noone here knows how to use). After asking around most agreed that it was a good idea, so i brought my books, made a simple printed sheet with "Book A belongs to B" and "Developer A took the Book on dd.mm.yyyy" to get it started. Now i want to get some ideas for Books that i could add to the shelf (sadly from my own money since 100€/month for training is too much money for this multi-million euro company). We develop mostly PHP & MySQL so books specific to this topic would be preferred but i think if people learn other languages they might get ideas on how to develop better with the current language so other books are ok, too. Which books would you recommend? PS: Personally i'd like to add some Project Management books, too, as it's a topic i'm interested in, eventhough i'm just a junior developer (We've got Peopleware already, great book btw).
