  • Show PDF in HTML in web

    - by Anil
    Hi, I'm using the object tag to render PDF in HTML, but I'm doing it in MVC like this: <object data="/JDLCustomer/GetPDFData?projID=<%=ViewData["ProjectID"]%>&folder=<%=ViewData["Folder"] %>" type="application/pdf" width="960" height="900"> </object> and Controller/Action is public void GetPDFData(string projID, Project_Thin.Folders folder) { Highmark.BLL.Models.Project proj = GetProject(projID); List<File> ff = proj.GetFiles(folder, false); if (ff != null && ff.Count > 0 && ff.Where(p => p.FileExtension == "pdf").Count() > 0) { ff = ff.Where(p => p.FileExtension == "pdf").ToList(); Response.ClearHeaders(); Highmark.BLL.PDF.JDLCustomerPDF pdfObj = new JDLCustomerPDF(ff, proj.SimpleDbID); byte[] bArr = pdfObj.GetPDF(Response.OutputStream); pdfObj = null; Response.ContentType = "application/" + System.IO.Path.GetExtension("TakeOffPlans").Replace(".", ""); Response.AddHeader("Content-disposition", "attachment; filename=\"TakeOffPlans\""); Response.BinaryWrite(bArr); Response.Flush(); } } The problem is, as I'm downloading data first from server and then return the byte data, it is taking some time in downloading, so I want to show some kind of progress to show processing. Please help me on this.

  • Misalignement in the output Bitmap created from a byte array

    - by Daniel
    I am trying to understand why I have troubles creating a Bitmap from a byte array. I post this after a careful scrutiny of the existing posts about Bitmap creation from byte arrays, like the followings: Creating a bitmap from a byte[], Working with Image and Bitmap in c#?, C#: Bitmap Creation using bytes array My code is aimed to execute a filter on a digital image 8bppIndexed writing the pixel value on a byte [] buffer to be converted again (after some processing to manage gray levels) in a 8BppIndexed Bitmap My input image is a trivial image created by means of specific perl code: https://www.box.com/shared/zqt46c4pcvmxhc92i7ct Of course, after executing the filter the output image has lost the first and last rows and the first and last columns, due to the way the filter manage borders, so from the original 256 x 256 image i get a 254 x 254 image. Just to stay focused on the issue I have commented the code responsible for executing the filter so that the operation really performed is an obvious: ComputedPixel = InputImage.GetPixel(myColumn, myRow).R; I know, i should use lock and unlock but I prefer one headache one by one. Anyway this code should be a sort of identity transform, and at last i use: private unsafe void FillOutputImage() { OutputImage = new Bitmap (OutputImageCols, OutputImageRows , PixelFormat .Format8bppIndexed); ColorPalette ncp = OutputImage.Palette; for (int i = 0; i < 256; i++) ncp.Entries[i] = Color .FromArgb(255, i, i, i); OutputImage.Palette = ncp; Rectangle area = new Rectangle(0, 0, OutputImageCols, OutputImageRows); var data = OutputImage.LockBits(area, ImageLockMode.WriteOnly, OutputImage.PixelFormat); Marshal .Copy (byteBuffer, 0, data.Scan0, byteBuffer.Length); OutputImage.UnlockBits(data); } The output image I get is the following: https://www.box.com/shared/p6tubyi6dsf7cyregg9e It is quite clear that I am losing a pixel per row, but i cannot understand why: I have carefully controlled all the parameters: OutputImageCols, OutputImageRows and the byte [] byteBuffer length and content even writing known values as way to test. The code is nearly identical to other code posted in stackOverflow and elsewhere. Someone maybe could help to identify where the problem is? Thanks a lot

  • Conflict between two Javascripts (MailChimp validation etc. scripts & jQuery hSlides.js)

    - by Brian
    I have two scripts running on the same page, one is the jQuery.hSlides.js script http://www.jesuscarrera.info/demos/hslides/ and the other is a custom script that is used for MailChimp list signup integration. The hSlides panel can be seen in effect here: http://theatricalbellydance.com. I've turned off the MailChimp script because it was conflicting with the hSlides script, causing it not to to fail completely (as seen here http://theatricalbellydance.com/home2/).

    I have a web service with the following contract: POST /Service/service.asmx HTTP/1.1 Host: xxx.xxx.xxx Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "xxx.xxx.xxx/Service/Method" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <Request xmlns="xxx.xxx.xxx/Service/"> <transactiontype>string</transactiontype> <username>string</username> <password>string</password> </Request> </soap:Header> <soap:Body> <Method xmlns="xxx.xxx.xxx/Service/"> <xml>xml</xml> </Method> </soap:Body> </soap:Envelope> And I am trying to call the service using jquery.

  • Perform Grouping of Resultsets in Code, not on Database Level

    - by NinjaBomb
    Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it? EDIT I have attempted to group the result in SQL using the exact same grouping query suggested by Thomas Levesque and both times our entire RDBMS crashed trying to process the query. I was under the impression that Linq was not available until .NET 3.5. This is a .NET 2.0 web application so I did not think it was an option. Am I wrong in thinking that? EDIT Starting a bounty because I believe this would be a good technique to have in the toolbox to use no matter where the different resultsets are coming from. I believe knowing the most concise way to group any 2 somewhat similar sets of data in code (without .NET LINQ) would be beneficial to more people than just me.

  • Escaping single quote in PHP when inserting into MySQL

    - by hairdresser-101
    PLEASE NOTE: I am reposting as the original was not answered correctly... I AM LOOKING FOR THE WHY - NOT THE SOLUTION - I KNOW THE SOLUTION, WHAT I DON'T UNDERSTAND IS THE WHY! I have a perplexing issue that I can't seem to comprehend... I'm hoping someone here might be able to point me in the right direction... I have two SQL statements: - the first enters information from a form into the database. - the second takes data from the database entered above, sends an email and then logs the details of the transaction The problem is that it a appears that a single quote is triggering a MySQL error on the second entry only!!! The first instance works without issue but the second instance triggers the mysql_error(). Does the data from a form get handled differently from the data captured in a form? Query#1 - This works without issue (and without escaping the single quote) $result = mysql_query("INSERT INTO job_log (order_id, supplier_id, category_id, service_id, qty_ordered, customer_id, user_id, salesperson_ref, booking_ref, booking_name, address, suburb, postcode, state_id, region_id, email, phone, phone2, mobile, delivery_date, stock_taken, special_instructions, cost_price, cost_price_gst, sell_price, sell_price_gst, ext_sell_price, retail_customer, created, modified, log_status_id) VALUES ('$order_id', '$supplier_id', '$category_id', '{$value['id']}', '{$value['qty']}', '$customer_id', '$user_id', '$salesperson_ref', '$booking_ref', '$booking_name', '$address', '$suburb', '$postcode', '$state_id', '$region_id', '$email', '$phone', '$phone2', '$mobile', STR_TO_DATE('$delivery_date', '%d/%m/%Y'), '$stock_taken', '$special_instructions', '$cost_price', '$cost_price_gst', '$sell_price', '$sell_price_gst', '$ext_sell_price', '$retail_customer', '".date('Y-m-d H:i:s', time())."', '".date('Y-m-d H:i:s', time())."', '1')"); Query#2 - This fails when entering a name with a single quote (i.e. O'Brien) $query = mysql_query("INSERT INTO message_log (order_id, timestamp, message_type, email_from, supplier_id, primary_contact, secondary_contact, subject, message_content, status) VALUES ('$order_id', '".date('Y-m-d H:i:s', time())."', '$email', '$from', '$row->supplier_id', '$row->primary_email' ,'$row->secondary_email', '$subject', '$message_content', '1')");

  • Unit test insert/update/delete

    - by Kurresmack
    Hey, I have googled this a little and didn't really find the answer I needed. I am working on a webpage in C# with MSSQL and LINQ for a customer. I want the users to be able to send messages to each other. So what I do is that I unit test this with data that actually goes into the database. The problem is that I now depend on having at least 2 users who I know the ID of. Furthermore I have to clean up after my self. This leads to rather large unit tests that test alot in one test. Lets say I would like to update a user. That would mean that I would have to ceate the user, update it, and then delete it. This a lot of assertions in one unit test and if it fails with updating i have to manually delete it. If I would do it any other way, without saving the data to DB, I would not for sure be able to know that the data was present in the database after updating etc. What is the proper way to do this without having a test that tests a lot of functuality in one test?

  • What is the right approach to checksumming UDP packets

    - by mr.b
    I'm building UDP server application in C#. I've come across a packet checksum problem. As you probably know, each packet should carry some simple way of telling receiver if packet data is intact. Now, UDP already has 2-byte checksum as part of header, which is optional, at least in IPv4 world. Alternative method is to have custom checksum as part of data section in each packet, and to verify it on receiver. My question boils down to: is it better to rely on (optional) checksum in UDP packet header, or to make a custom checksum implementation as part of packet data section? Perhaps the right answer depends on circumstances (as usual), so one circumstance here is that, even though code is written and developed in .NET on Windows, it might have to run under platform-independent Mono.NET, so eventual solution should be compatible with other platforms. I believe that custom checksum algorithm would be easily portable, but I'm not so sure about the first one. Any thoughts? Also, shouts about packet checksumming in general are welcome.

  • inverse relation to multiple inheriting classes in django

    - by Ofri Raviv
    Here are my schematic models: class Law(models.Model): ... class Bill(models.Model): ... # data for a proposed law, or change of an existing law class PrivateBill(Bill): ... # data for a Bill that was initiated by a parliament member class GovernmentBill(Bill): ... # data for a Bill that was initiated by the government It is possible and likely that in the future I (or maybe someone else) would want to add more Bill types. Every Bill should point to a Law (indicating what law this bill is going to change) and my question is: What is the best way to implement this? If I add the ForeignKey(Law) to Bill, I'll have a relation from every Bill to Law, but a Law would only have an inverse relation to Bills (bill_set), and not a different inverse relation to each type of bill. Of course I'll be able to filter each type of bill to get only the ones pointing to a specific Law, but this is something I think I'll need to use often, so I think having privatebill_set, governmentbill_set etc would make the code more readable. Another possible solution is to add the foreign key to each of the inheriting classes (this would give me a privatebill_set, governmentbill_set, futurebill_set), but that seems hairy because I would be relying on future programmers to remember to add that relation. How would you solve this?

  • Serial.begin(speed, config) not compiling for Leonardo Board

    - by forgemo
    I would like to configure my serial communication to have no parity, 1 start- and 2 stop-bits. The documentation for Serial.begin(speed, config) states: (...) An optional second argument configures the data, parity, and stop bits. The default is 8 data bits, no parity, one stop bit. The documentation also lists the possible configuration-values. According to my (limited) understanding, I need SERIAL_7N2 or SERIAL_8N2 to meet my requirements. (I'm not sure how the data-bits relate to the the 1-start-bit that I need.) However, I can't even compile because I have no idea how to supply that config value to the begin method. (I don't have much Arduino/C++ experience) I've tried in my code the following two variants: Serial.begin(9600, SERIAL_8N2); Serial.begin(9600, "SERIAL_8N2"); Am I missing something? Additional Information: Serial.begin(speed, config) has been introduced with the latest Arduino 1.0.2 IDE version. The code defining/implementing the begin methods can be found here. HardwareSerial.h HardwareSerial.cpp Edit: According to the replies from PeterJ and borges, the following variant is correct. Serial.begin(9600, SERIAL_8N2); However, it's still not working. I found that the compile error doesn't occur if I change the configured board from my Arduino Leonardo to Arduino uno. Therefore, it could be a bug occurring only with a subset of boards ... or maybe it's not supported?!

  • WPF ListView GridView DisplayMemberBinding Center alignin content

    - by Bigginn
    I'm trying to center align data in a ListView/Gridview where I use DisplayMemberBinding. This is (partially) how my gridview looks: <ListView> <ListView.View> <GridView> <GridView.Columns> <GridViewColumn DisplayMemberBinding="{Binding Path=Timi}" Width="Auto"> <GridViewColumnHeader Content="Tími" Click="GridViewColumnHeader_Click" ></GridViewColumnHeader> </GridViewColumn> </GridView.Columns> </GridView> </ListView.View> </ListView> I tried to use CellTemplate like explained on this page http://msdn.microsoft.com/en-us/library/system.windows.controls.gridviewcolumn.celltemplate.aspx but it didn't work and then later I read somewhere that one should never use cellTemplate and DisplayMemberBinding together. So the question is : How do I center the gridview data when I use DisplayMemberBinding to bind the data to the gridview? Thanks in advance.

    - by Grzegorz
    I have two entities, A and B. I need to easily retrieve entities A, joined with entities B on the condition of equal values of some column (some column from A equal to some column in B). Those columns are not primary or foreign keys, they contain same business data. I just need to have access from each instance of A to the collection of B's with the same value of this column. So I model it like this: class A { @OneToMany @JoinColumn(name="column_in_B", referencedColumnName="column_in_A") Collection<B> bs; This way, I can run queries like "select A join fetch a.bs b where b...." (Actually, the real relationship here is many-to-many. But when I use @ManyToMany, Hibernate forces me to use join table, which doesnt exist here. So I have to use @OneToMany as workaround). So far so good. The main problem is: whenever I delete an instance of A, hibernate calls "Update B set column_in_B = null", becuase it thinks the column_in_B is foreign key pointing at primary key in A (and because row in A is deleted, it tries to clean the foreign key in B). BUT the column_in_B IS NOT a foreign key, and can't be modified, because it causes data lost (and this column is NOT NULL anyway in my case, causing data integerity exception to be thrown). Plese help me with this. How to model such relationships with Hibernate? (I would call it "virtual relationships", or "secondary relationships" or so: as they are not based on foreign keys, they are just some shortcuts which allows for retrieving related objects and quering for them with HQL)

  • Is it possible to output cache by host name? ie varybyhost or varbyhostheader?

    - by Pure.Krome
    Hi folks, i've got a website that has a number of host headers. Depending on the host header, the results are different - both visually (theme'd) and data. So lets imagine i have a website called 'Foo' - that returns search results (original, eh?). Now, the same code runs both sites. It is physically the same server/website (using Host Headers) :- www.foo.com www.foo.com.au Now, if i goto '.com', the site is theme'd in blue. if i goto the '.com.au' site, it's theme'd in red. And the data is different for the same search result, based on the host name (ie. us results for .com, au results for .com.au) SO .. if i wish to use OutputCaching .. can this be handled / differ by the host name? I don't want to have the first person goto the .com site .. grab the results ... and the a second person goto my .com.au .. same search data .. and get the theme and results for the .com site. Possible?

  • "do it all" page structure and things to watch out for?

    - by Andrew Heath
    I'm still getting my feet wet in PHP (my 1st language) and I've reached the competency level where I can code one page that handles all sorts of different related requests. They generally have a structure like this: (psuedo code) <?php include 'include/functions.php'; IF authorized IF submit (add data) ELSE IF update (update data) ELSE IF list (show special data) ELSE IF tab switch (show new area) ELSE display vanilla (show default) ELSE "must be registered/logged-in" ?> <HTML> // snip <?php echo $output; ?> // snip </HTML> and it all works nicely, and quite quickly which is cool. But I'm still sorta feeling my way in the dark... and would like some input from the pros regarding this type of page design... is it a good long-term structure? (it seems easily expanded...) are there security risks particular to this design? are there corners I should avoid painting myself into? Just curious about what lies ahead, really...

  • PDF Form Field Manipulation

    - by 108039818756939362532
    I'm making a web interface to autofill pdf forms with user data from a database. The admin needs to be able to upload a pdf (right now targeted at IRS pdf forms) and then associate the fields in the pdf with data fields in the database. I need a way to help the admin associate the field names (stuff like "topmostSubform[0].Page2[0].p2-t66[0]") with the the data fields in the database. I'm looking for a way to modify the PDF programatically to in some way provide this information. Basically I'm open to suggestions on how I might make the field names appear in an obvious manner on a modified version of the original pdf. The closest I've gotten is being able to insert Tooltips into the fields in the pdf by just editting the raw pdf line by line. However when editting the pdf in this manner the field names are gibberish, and so I can't just use them. An optimal solution would be anything that could automatically parse a pdf and set each field's tooltip to be the fields name. Anything that can be run from the command line, or any python tool, or just a basic how to correctly parse a field's name from a raw pdf file would be amazing.

  • best way to switch between secure and unsecure connection without bugging the user

    - by Brian Lang
    The problem I am trying to tackle is simple. I have two pages - the first is a registration page, I take in a few fields from the user, once they submit it takes them to another page that processes the data, stores it to a database, and if successful, gives a confirmation message. Here is my issue - the data from the user is sensitive - as in, I'm using an https connection to ensure no eavesdropping. After that is sent to the database, I'd like on the confirmation page to do some nifty things like Google Maps navigation (this is for a time reservation application). The problem is by using the Google Maps api, I'd be linking to items through a unsecure source, which in turn prompts the user with a nasty warning message. I've browsed around, Google has an alternative to enterprise clients, but it costs $10,000 a year. What I am hoping is to find a workaround - use a secure connection to take in the data, and after it is processed, bring them to a page that isn't secure and allows me to utilize the Google Maps API. If any of you have a Netflix account you can see exactly what I would like to do when you sign-in, it is a secure page, which then takes you to your account / queue, on an unsecure page. Any suggestions? Thanks!

  • Troubleshooting FORM POST problems

    - by brettr
    I'm using the following code to submit to a WCF service. I keep getting an error that the key is invalid. I have a webpage on the same server that I submit the same data (but different key) using a FORM POST. It works fine that way. I put the URL below all in a URL (including valid key from server webpage) and get the key is invalid error. I'm thinking the data I'm submitting through the iPhone isn't really going across as a FORM POST but rather as a URL. Is there anything I may be doing wrong in the following code or any other suggestions? NSString *stringForURL = @"https://abc.com/someservice.aspx"; NSURL *URL=[[NSURL alloc] initWithString:stringForURL]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL]; NSString *request_body = [NSString stringWithFormat:@"prop1=value1&key=%@", [@"r2xHEuzgDTQEWA5Xe6+k9BSVrgsMX2mWQBW/39nqT4s=" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSData *postData = [request_body dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [NSThread sleepForTimeInterval:1]; self.receivedData = [[NSMutableData data] retain];

  • Changing the color of dot depending from value on Morris js graph

    - by Michal Lipa
    Im rendering graph by morris js. Im using data from mysql database by JSON. Everything works fine, but I would like to add one more feature to the graph. (change dot color if there is something in buy action). My JSON: [{"longdate":"2014-08-20 18:20:01","price":"1620","action":"buy"},{"longdate":"2014-08-20 18:40:01","price":"1640","action":""},{"longdate":"2014-08-20 19:00:01","price":"1620","action":""}] So I would like to change dot color for values with buy action. My code for graph: $.getJSON('results.json', function(day_data) { Morris.Line({ element: 'graph', data: day_data, xkey: 'longdate', ykeys: ['price'], labels: ['Cena'], lineColors: lineColor, pointSize: 0, hoverCallback: function(index, options, content) { var date = "<b><font color='black'>Data: "+day_data[index]['longdate']+"</font></b><br>"; var param1 = "<font color='"+lineColor[0]+"'>Cena - "+day_data[index]['price']+"</font><br>"; return date+param1; }, xLabelFormat : function (x) { return changeDateFormat(x); } /*My TRIAL if(action == 'buy'){ pointSize: 4, lineColors: green, } */ }); }); So my code doesnt work, how can I make this working?

  • How to terminate all [grand]child processes using C# on WXP (and newer MSWindows)

    - by NVRAM
    Question: How can I determine all processes in the child's Process Tree to kill them? I have an application, written in C# that will: Get a set of data from the server, Spawn a 3rd party utility to process the data, then Return the results to the server. This is working fine. But since a run consumes a lot of CPU and may take as long as an hour, I want to add the ability to have my app terminate its child processes. Some issues that make the simple solutions I've found elsewhere are: My app's child process "A" (InstallAnywhere EXE I think) spawns the real processing app "B" (a java.exe), which in turns spawns more children "C1".."Cn" (most of which are also written in Java). There will likely be multiple copies of my application (and hence, multiple sets of its children) running on the same machine. The child process is not in my control so there might be some "D" processes in the future. My application must run on 32-bit and 64-bit versions of MSWindows. On the plus side there is no issue of data loss, a "clean" shutdown doesn't matter as long as the processes end fairly quickly.

  • MVVM: Thin ViewModels and Rich Models

    - by Dan Bryant
    I'm continuing to struggle with the MVVM pattern and, in attempting to create a practical design for a small/medium project, have run into a number of challenges. One of these challenges is figuring out how to get the benefits of decoupling with this pattern without creating a lot of repetitive, hard-to-maintain code. My current strategy has been to create 'rich' Model classes. They are fully aware that they will be consumed by an MVVM pattern and implement INotifyPropertyChanged, allow their collections to be observed and remain cognizant that they may always be under observation. My ViewModel classes tend to be thin, only exposing properties when data actually needs to be transformed, with the bulk of their code being RelayCommand handlers. Views happily bind to either ViewModels or Models directly, depending on whether any data transformation is required. I use AOP (via Postsharp) to ease the pain of INotifyPropertyChanged, making it easy to make all of my Model classes 'rich' in this way. Are there significant disadvantages to using this approach? Can I assume that the ViewModel and View are so tightly coupled that if I need new data transformation for the View, I can simply add it to the ViewModel as needed?

  • How can I know when a Button in a Flex DataGrid itemRenderer is clicked?

    - by Eric Belair
    I have a DataGrid component that displays a few columns of data. It has one additional column that displays a Button that allows the user to take an action with regard to the record. <mx:DataGrid dataProvider="{myData}"> <mx:columns> <mx:DataGridColumn dataField="firstName" headerText="First Name" width="75" /> <mx:DataGridColumn dataField="LastName" headerText=" Last Name" width="150" /> <mx:DataGridColumn dataField="phone" headerText="Phone" width="120" /> <mx:DataGridColumn headerText="" width="110"> <mx:itemRenderer> <mx:Component> <mx:Box horizontalAlign="center" width="100%"> <mx:Button label="Take Action" /> </mx:Box> </mx:Component> </mx:itemRenderer> </mx:DataGridColumn> </mx:columns> </mx:DataGrid> I need to perform an action in the parent component, using other data that is available there, but unrelated to the data in the DataGrid. What is the best way to catch the Button click in the parent component, and know what record it corresponds to? Should I use a Custom Event, or an itemEditor, or something else completely?

  • c# web extracting programming, which libraries, examples samples please

    - by user287745
    I have just started programming and have made a few small applications in C and C#. My understanding is that programming for web and thing related to web is nowadays a very easy task. Please note this is for personnel learning, not for rent a coder or any money making. An application which can run on any Windows platform even Windows 98. The application should start automatically at a scheduled time and do the following. Connect to a site which displays stock prices summary (high low current open). Capture the data (excluding the other things in the site.) And save it to disk (an SQL database) Please note:- Internet connection is assumed to be there always. Do not want to know how to make database schema or database. The stock exchange has no law prohibiting the use of the data provided on its site, but I do not want to mention the name in case I am wrong, but it's for personal private use only. The data of summary of pricing is arranged in a table such that when copied pasted to MS Excel it automatically forms a table. need steps guidance please, examples, lbraries

  • Rijndael managed: plaintext length detction

    - by sheepsimulator
    I am spending some time learning how to use the RijndaelManaged library in .NET, and developed the following function to test encrypting text with slight modifications from the MSDN library: Function encryptBytesToBytes_AES(ByVal plainText As Byte(), ByVal Key() As Byte, ByVal IV() As Byte) As Byte() ' Check arguments. If plainText Is Nothing OrElse plainText.Length <= 0 Then Throw New ArgumentNullException("plainText") End If If Key Is Nothing OrElse Key.Length <= 0 Then Throw New ArgumentNullException("Key") End If If IV Is Nothing OrElse IV.Length <= 0 Then Throw New ArgumentNullException("IV") End If ' Declare the RijndaelManaged object ' used to encrypt the data. Dim aesAlg As RijndaelManaged = Nothing ' Declare the stream used to encrypt to an in memory ' array of bytes. Dim msEncrypt As MemoryStream = Nothing Try ' Create a RijndaelManaged object ' with the specified key and IV. aesAlg = New RijndaelManaged() aesAlg.BlockSize = 128 aesAlg.KeySize = 128 aesAlg.Mode = CipherMode.ECB aesAlg.Padding = PaddingMode.None aesAlg.Key = Key aesAlg.IV = IV ' Create a decrytor to perform the stream transform. Dim encryptor As ICryptoTransform = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV) ' Create the streams used for encryption. msEncrypt = New MemoryStream() Using csEncrypt As New CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write) Using swEncrypt As New StreamWriter(csEncrypt) 'Write all data to the stream. swEncrypt.Write(plainText) End Using End Using Finally ' Clear the RijndaelManaged object. If Not (aesAlg Is Nothing) Then aesAlg.Clear() End If End Try ' Return the encrypted bytes from the memory stream. Return msEncrypt.ToArray() End Function Here's the actual code I am calling encryptBytesToBytes_AES() with: Private Sub btnEncrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEncrypt.Click Dim bZeroKey As Byte() = {&H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0} PrintBytesToRTF(encryptBytesToBytes_AES(bZeroKey, bZeroKey, bZeroKey)) End Sub However, I get an exception thrown on swEncrypt.Write(plainText) stating that the 'Length of the data to encrypt is invalid.' However, I know that the size of my key, iv, and plaintext are 16 bytes == 128 bits == aesAlg.BlockSize. Why is it throwing this exception? Is it because the StreamWriter is trying to make a String (ostensibly with some encoding) and it doesn't like &H0 as a value?
