  • how to show attached files on a TMS WebGrid ???

    - by ahmed
    hi, i have a TMS WebGrid , I would like to attach some files ad show them on a Tms WebGrid. How can I do that in vb.net ? For now I am simply attaching like this on a attach file button ?? If Len(FileUpload1.PostedFile.FileName) > 5 Then length = FileUpload1.PostedFile.InputStream.Length() My_Img_Path = "Attachments/" k_upload_dir = "~/Attachments/" virtualPath = k_upload_dir + my_img_srno.ToString + Path.GetFileName(FileUpload1.PostedFile.FileName) My_Img_Path = My_Img_Path + my_img_srno.ToString + Path.GetFileName(FileUpload1.PostedFile.FileName) phyiscalPath = Server.MapPath(virtualPath) FileUpload1.PostedFile.SaveAs(phyiscalPath) my_html_code = "" lbl_AttahcmnetStatus.Text = "Sucessfully file attached..." end if

  • Faster Matrix Multiplication in C#

    - by Kyle Lahnakoski
    I have as small c# project that involves matrices. I am processing large amounts of data by splitting it into n-length chunks, treating the chucks as vectors, and multiplying by a Vandermonde** matrix. The problem is, depending on the conditions, the size of the chucks and corresponding Vandermonde** matrix can vary. I have a general solution which is easy to read, but way too slow: public byte[] addBlockRedundancy(byte[] data) { if (data.Length!=numGood) D.error("Expecting data to be just "+numGood+" bytes long"); aMatrix d=aMatrix.newColumnMatrix(this.mod, data); var r=vandermonde.multiplyBy(d); return r.ToByteArray(); }//method This can process about 1/4 megabytes per second on my i5 U470 @ 1.33GHz. I can make this faster by manually inlining the matrix multiplication: int o=0; int d=0; for (d=0; d<data.Length-numGood; d+=numGood) { for (int r=0; r<numGood+numRedundant; r++) { Byte value=0; for (int c=0; c<numGood; c++) { value=mod.Add(value, mod.Multiply(vandermonde.get(r, c), data[d+c])); }//for output[r][o]=value; }//for o++; }//for This can process about 1 meg a second. (Please note the "mod" is performing operations over GF(2^8) modulo my favorite irreducible polynomial.) I know this can get a lot faster: After all, the Vandermonde** matrix is mostly zeros. I should be able to make a routine, or find a routine, that can take my matrix and return a optimized method which will effectively multiply vectors by the given matrix, but faster. Then, when I give this routine a 5x5 Vandermonde matrix (the identity matrix), there is simply no arithmetic to perform, and the original data is just copied. ** Please note: What I use the term "Vandermonde", I actually mean an Identity matrix with some number of rows from the Vandermonde matrix appended (see comments). This matrix is wonderful because of all the zeros, and because if you remove enough rows (of your choosing) to make it square, it is an invertible matrix. And, of course, I would like to use this same routine to convert any one of those inverted matrices into an optimized series of instructions. How can I make this matrix multiplication faster? Thanks! (edited to correct my mistake with Vandermonde matrix)

  • Delphi Unicode String Type Stored Directly at its Address

    - by Andreas Rejbrand
    I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right?

  • File upload progress

    - by Cornelius
    I've been trying to track the progress of a file upload but keep on ending up at dead ends (uploading from a C# application not a webpage). I tried using the WebClient as such: class Program { static volatile bool busy = true; static void Main(string[] args) { WebClient client = new WebClient(); // Add some custom header information client.Credentials = new NetworkCredential("username", "password"); client.UploadProgressChanged += client_UploadProgressChanged; client.UploadFileCompleted += client_UploadFileCompleted; client.UploadFileAsync(new Uri("http://uploaduri/"), "filename"); while (busy) { Thread.Sleep(100); } Console.WriteLine("Done: press enter to exit"); Console.ReadLine(); } static void client_UploadFileCompleted(object sender, UploadFileCompletedEventArgs e) { busy = false; } static void client_UploadProgressChanged(object sender, UploadProgressChangedEventArgs e) { Console.WriteLine("Completed {0} of {1} bytes", e.BytesSent, e.TotalBytesToSend); } } The file does upload and progress is printed out but the progress is much faster than the actual upload and when uploading a large file the progress will reach the maximum within a few seconds but the actual upload takes a few minutes (it is not just waiting on a response, all the data have not yet arrived at the server). So I tried using HttpWebRequest to stream the data instead (I know this is not the exact equivalent of a file upload as it does not produce multipart/form-data content but it does serve to illustrate my problem). I set AllowWriteStreamBuffering to false and set the ContentLength as suggested by this question/answer: class Program { static void Main(string[] args) { FileInfo fileInfo = new FileInfo(args[0]); HttpWebRequest client = (HttpWebRequest)WebRequest.Create(new Uri("http://uploadUri/")); // Add some custom header info client.Credentials = new NetworkCredential("username", "password"); client.AllowWriteStreamBuffering = false; client.ContentLength = fileInfo.Length; client.Method = "POST"; long fileSize = fileInfo.Length; using (FileStream stream = fileInfo.OpenRead()) { using (Stream uploadStream = client.GetRequestStream()) { long totalWritten = 0; byte[] buffer = new byte[3000]; int bytesRead = 0; while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0) { uploadStream.Write(buffer, 0, bytesRead); uploadStream.Flush(); Console.WriteLine("{0} of {1} written", totalWritten += bytesRead, fileSize); } } } Console.WriteLine("Done: press enter to exit"); Console.ReadLine(); } } The request does not start until the entire file have been written to the stream and already shows full progress at the time it starts (I'm using fiddler to verify this). I also tried setting SendChunked to true (with and without setting the ContentLength as well). It seems like the data still gets cached before being sent over the network. Is there something wrong with one of these approaches or is there perhaps another way I can track the progress of file uploads from a windows application?

  • Iterate over framesets with XPath expression in JavaScript?

    - by Derek Mahar
    Why does the following JavaScript, when run in Firefox 3.6.3, delete all FRAMESET elements in a document, but the similar script that instead uses an XPath expression to select the FRAMESET elements, does not? Is document.evaluate() simply unable to match FRAMESET elements? Is there an error in the XPath expression? Is there some other error? Select all FRAMESET elements using method document.getElementsByTagName() (succeeds): var framesets = document.getElementsByTagName('frameset'); for (var i = 0; i < framesets.length; i++) { framesets[i].parentNode.removeChild(framesets[i]); } Select all FRAMESET elements using an XPath expression (fails): var framesets = document.evaluate("//frameset", document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null); for (var i = 0; i < framesets.length; i++) { framesets[i].parentNode.removeChild(framesets[i]); }

  • Fading in/Fade out text in IE

    - by tau
    I had a problem and whipped up a quick solution: fade-in and fade-out a series of quotations. My solution works just as I want it in every browser except any of the IEs. The only problem with the IEs is that the text does not fade in and fade out; the text simply pops into existence. I believe I've run into a similar problem before when trying to dynamically change the filter:alpha(opacity=xx) of an element. Any help is greatly appreciated! <html> <head> <style> .fadetext{ background:green; border:1px solid red; height:50px; width:500px; } .fadetext div{ background:yellow; } </style> <script type="text/javascript"> var CI_common = { C:function(cls,elm){ if(!elm) elm = document; if(document.getElementsByClassName){ return elm.getElementsByClassName(cls); }else{ var t = []; var o = elm.getElementsByTagName("*"); var r = new RegExp("(^|\\s)" + cls + "($|\\s)"); for(var i=0;i<o.length;i++){ if(o[i].className.match(r)) t.push(o[i]); } return t; } }, eventAdd:function(obj,evt,func){ if(obj.addEventListener){ obj.addEventListener(evt,func,false); }else if(obj.attachEvent){ obj["x" + evt + func] = func; obj[evt + func] = function(){ obj["x" + evt + func](window.event); } obj.attachEvent("on" + evt,obj[evt + func]); } } } var CI_fadetext = { init:function(){ var c = CI_common.C("fadetext"); // Simply a getElementsByClassName function for(var i=0;i<c.length;i++){ c[i].style.overflow = "hidden"; var kids = c[i].getElementsByTagName("div"); for(var j=0;j<kids.length;j++){ kids[j].style.display = "none"; kids[j].style.filter = "alpha(opacity=0)"; kids[j].style.opacity = "0"; (function(obj,index,len){ obj.fadetexttimeout = setTimeout(function(){ CI_fadetext.fade(obj,true); obj.fadeininterval = setInterval(function(){ CI_fadetext.fade(obj,true); },5000*len) },5000*index); setTimeout(function(){ CI_fadetext.fade(obj,false); obj.fadeoutinterval = setInterval(function(){ CI_fadetext.fade(obj,false); },5000*len) },5000*index+4400); })(kids[j],j,kids.length); } } }, fade:function(elm,dir){ function fade(start){ start = (dir ? start + 10 : start - 10); elm.style.filter = "alpha(opacity=" + start + ")"; elm.style.opacity = start/100; document.getElementById("output").innerHTML = elm.style.filter; if(start > 100 || start <0){ elm.style.display = (dir ?

  • How mod_cache working with "must-revalidate" and "max-age"?

    - by Dmitriy Sosunov
    Quick question before I will explain my flow: ?an mod_cache perform revalidate with if-none-match only if max-age is expired in case if it configured in reverse proxy mode? My goal is to reduce a number of revalidation requests to our the origin server. For instance: The first request goes to the origin server and then mod_cache save a response in to the cache according to header cache-control: max-age. And only when max-age is expired then mod_cache will revalidate with if-none-match. Currently, mod_cache revalidate each request, regardless that max-age is defined or not. My configuration of Apache 2.4.3 (Windows), on linux I see the same behavior that I will show below. ServerName proxy.lo ProxyRequests Off ProxyPreserveHost Off Header set Vary "Accept, Content-Type, Content-Encoding, Accept-Language" RequestHeader set X-Forwarded-Proto "http" # modify header for user agent's Header set Cache-Control "private, no-cache, no-store, no-transform" CacheQuickHandler off CacheDefaultExpire 300 # the origin server do not provide last-modified CacheIgnoreNoLastMod On CacheIgnoreCacheControl On # the origin server define cache-control: private, no-store only for user agents # Therefore, I would like ignore those headers on the proxy server. CacheStorePrivate On CacheStoreNoStore On CacheEnable disk / CacheRoot "C:/Apache.Cache" CacheDirLevels 5 CacheDirLength 4 CacheMinExpire 15 CacheDetailHeader on CacheHeader on KeepAlive Off ProxyPass / http://origin.lo/ ProxyPassReverse / http://origin.lo/ Also, I have turned on debug log level to see how mod_cache handles a content for caching: I provided this to show that mod_proxy always decides that a content isn't fresh. Why?I provided this to show that mod_proxy always decide that a content isn't fresh. Why? max-age was provided (see below).

  • How to create a vector of lists in R?

    - by Martin
    Hi, I have a list (tmpList), which looks like this: $op [1] "empty" $termset $termset$field [1] "entry" $termset[[2]] $termset[[2]]$explode [1] "Y" This is a list with a list inside. If I add this list to a vector theOneVector = c(theOneVector, tmpList) Now the resulting vector is of the length 2, because the first entry ("op") of the list is separated from the tmpList. Is it possible to append the complete tmpList into this vector? I already tried it with theOneVector = c(theOneVector, list(tmpList)) which gives a vector with the length of 1, but it is very cumbersome to access the elements of the list with this extra list around the list. (Too much list in one sentence I think.) Any help would be appreciated, Martin

  • Can I use ruby rest-client to POST a binary file to an http API?

    - by Angela
    I have been using rest-client in ruby in post XML to a third-party API. I need to be able to include a binary image that's uploaded. How do I do that? Uploading Attachments Both letters and postcards will, in most cases, require the attachment of documents. Those attachments might be PDFs in the case of letters or images in the case of postcards. To uploading an attachment, submit a POST to: http://www.postful.com/service/upload Be sure to include the Content-Type and Content-Length headers and the attachment itself as the body of the request. POST /upload HTTP/1.0 Content-Type: application/octet-stream Content-Length: 301456 ... file content here ... If the upload is successful, you will receive a response like the following: 290797321.waltershandy.2

  • Question About MP4(AAC) Binary Tree

    - by DeanMc
    I'm in the very early stages of working on a tag editor for mp4 files and more specifically iTunes AAC ones. After doing some snooping around it seems that the file's structure is not as complicated as I first thought and is built in a sort of tree like the following 4 Bytes [Atom Length] 4 Bytes [Atom Name] X Bytes [Atom Data] An atom's data is as large as the length and can contain either Data(information) or another atom. What I am trying to work out is how one determines if the data is information or an actual atom. Any insight would be much appreciated.

  • iPhone: didSelectRowAtIndexPath not invoked

    - by soletan
    Hi, I know this issue being mentioned before, but resolutions there didn't apply. I'm having a UINavigationController with an embedded UITableViewController set up using IB. In IB the UITableView's delegate and dataSource are both set to my derivation of UITableViewController. This class has been added using XCode's templates for UITableViewController classes. There is no custom UITableViewCell and the table view is using default plain style with single title, only. Well, in simulator the list is rendered properly, with two elements provided by dataSource, so dataSource is linked properly. If I remove the outlet link for dataSource in IB, an empty table is rendered instead. As soon as I tap on one of these two items, it is flashing blue and the GDB encounters interruption in __forwarding__ in scope of a UITableView::_selectRowAtIndexPath. It's not reaching breakpoint set in my non-empty method didSelectRowIndexPath. I checked the arguments and method's name to exclude typos resulting in different selector. I recently didn't succeed in whether delegate is set properly, but as it is set equivalently to dataSource which is getting two elements from the same class, I expect it to be set properly. So, what's wrong? I'm running iPhone/iPad SDK 3.1.2 ... but tried with iPhone SDK 3.1 in simulator as well. EDIT: This is the code of my UITableViewController derivation: #import "LocalBrowserListController.h" #import "InstrumentDescriptor.h" @implementation LocalBrowserListController - (void)viewDidLoad { [super viewDidLoad]; [self listLocalInstruments]; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [entries count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; if ( ( [entries count] > 0 ) && ( [indexPath length] > 0 ) ) cell.textLabel.text = [[[entries objectAtIndex:[indexPath indexAtPosition:[indexPath length] - 1]] label] retain]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if ( ( [entries count] > 0 ) && ( [indexPath length] > 0 ) ) { ... } } - (void)dealloc { [super dealloc]; } - (void) listLocalInstruments { NSMutableArray *result = [NSMutableArray arrayWithCapacity:10]; [result addObject:[InstrumentDescriptor descriptorOn:[[NSBundle mainBundle] pathForResource:@"example" ofType:@"idl"] withLabel:@"Default 1"]]; [result addObject:[InstrumentDescriptor descriptorOn:[[NSBundle mainBundle] pathForResource:@"example" ofType:@"xml"] withLabel:@"Default 2"]]; [entries release]; entries = [[NSArray alloc] initWithArray:result]; } @end

  • Closest Approach question for math/physics heads

    - by Kyle
    I'm using a Segment to Segment closest approach method which will output the closest distance between two segments of length. These objects are moving at variable speed each, so even when it succeeds I'm currently using a 10-step method and calculating the distance between 2 spheres as they move along the two segments. So, basically the length of each segment is the object's traverse in the physics step, and the radius is the objects radius. By stepping, I can tell where they collide, and if they collide (Sort of; for the MOST part.).. I get the feeling that there could be something better. While I sort of believe that the first closest approach call is required, I think that the method immediately following it is a TAD weak. Can anyone help me out? I can illustrate this if needed. Thanks alot!

  • Database Design Primay Key, ID vs String

    - by LnDCobra
    Hi, I am currently planning to develop a music streaming application. And i am wondering what would be better as a primary key in my tables on the server. An ID int or a Unique String. Methods 1: Songs Table: SongID(int), Title(string), Artist*(string), Length(int), Album*(string) Genre Table Genre(string), Name(string) SongGenre: SongID*(int), Genre*(string) Method 2 Songs Table: SongID(int), Title(string), ArtistID*(int), Length(int), AlbumID*(int) Genre Table GenreID(int), Name(string) SongGenre: SongID*(int), GenreID*(int) Key: Bold = Primary Key, Field* = Foreign Key I'm currently designing using method 2 as I believe it will speed up lookup performance and use less space as an int takes a lot less space then a string. Is there any reason this isn't a good idea? Is there anything I should be aware of?

  • iPhone SDK - Comparing characters in string

    - by Karl Daniel
    Basically what I'm trying to do is compare 2 strings one from a plist and one from the user's input. I use a while loop to step through each character and compare it and if true then I increase an integer then once the loop has finished I work out the percentage correct / similarity of the plist answer and the user's answer. I seem to be having a problem however as the only return I'm getting is 0. Below is the code I'm using... The code below is all functioning and the question no longer requires answering... Working code... answerLength = boxAnswer.length; //Gets number of characters of first string. plistLength = plistAnswer.length; //Gets number of characters of second string. characterRange = 0; //Sets the variable for which character to look at. charactersCorrect = 0; //Sets the variable of number of matching characters. unichar answerCharacter; //Declares a unichar for the first string. unichar plistCharacter; //Declares a unichar for the second string. while (answerLength > 0 && plistLength > 0) { answerCharacter = [boxAnswer characterAtIndex:characterRange]; //Gets character of first string at the index of the range integer. plistCharacter = [plistAnswer characterAtIndex:characterRange]; //Gets character of second string at the index of the range integer. answerLength--; //Reduces number of characters left to compare. plistLength--; characterRange++; //Increases integer to tell it to look at next character in string. if (answerCharacter == plistCharacter) { //Checks to see if character of first string and character of second string match. charactersCorrect++; //If true increases the number correct. } } //Works out percentage of matching characters out of the total string. totalChar = plistAnswer.length; totalPercentage = (charactersCorrect/totalChar)*100; percentageCorrect.text = [NSString stringWithFormat:@"%i%%",totalPercentage]; Variable Declarations... int answerLength; int plistLength; int characterRange; double totalChar; double charactersCorrect; int totalPercentage;

  • write() causes fatal crash when filedescriptor becomes invalid

    - by ckrames1234
    I'm writing an iPhone App with a webserver in it. To handle a web request, I take the web request and write() to it the data that I want to send back. When I try to download a moderately sized file (3-6MB) it works fine, but if I cancel the download halfway through, the app crashes and leaves no trace of an error. I'm thinking that the file descriptor becomes invalid halfway through the write, and causes the crash. I really don't know if this is what causes the crash, i'm just assuming. I'm basing my webserver off of this example. NSString *header = @""; NSData *data = [NSData dataWithContentsOfFile:fullPath]; write (fd, [header UTF8String], [header length]); write(fd, [data bytes], [data length]); close(fd); Does anyone know how to fix this? I was thinking about chunking the data and then writing each part, but I don't think it would help.
