• Closure Tables - Is this enough data to display a tree view?

  - by James Pitt

  Here is the table I have created by testing the closure table method. | id | parentId | childId | hops | | | | | 270 | 6 | 6 | 0 | 271 | 7 | 7 | 0 | 272 | 8 | 8 | 0 | 273 | 9 | 9 | 0 | 276 | 10 | 10 | 0 | 281 | 9 | 10 | 1 | 282 | 7 | 9 | 1 | 283 | 7 | 10 | 2 | 285 | 7 | 8 | 1 | 286 | 6 | 7 | 1 | 287 | 6 | 9 | 2 | 288 | 6 | 10 | 3 | 289 | 6 | 8 | 2 | 293 | 6 | 9 | 1 | 294 | 6 | 10 | 2 I am trying to create a simple tree of this using PHP. There does not seem to be enough data to create the table. For example, when I look purely at parentId = 6: -Part 6 -Part 7 - ? - ? -Part 9 - ? - ? We know that parts 8 and 10 exists below Part 7 or 9, but not which. We know that part 10 exists at both 3 and 4 nodes deep but where? If I look at other data in the table it is possible to tell it should be: - Part 6 - Part 7 - Part 9 - Part 10 - Part 9 - Part 10 I thought one of the benefits of closure tables was there was no need for recursive queries? Could you help explain what I am doing wrong? EDIT: For clarification, this is a mapping table. There is another table called "parts" which has a column called part_id that correlates to both the parentId and childId columns in the "closure" table. The "id" column in the table above (closure) is just for the purposes of maintaining a primary key. It is not really necessary. The methods I have used to create this closure table is described in the following article: http://dirtsimple.org/2010/11/simplest-way-to-do-tree-based-queries.html EDIT2: It can have two and three hops. I will explain easier by assigning names to the items. Part 6 = Bicycle Part 7 = Gears Part 8 = Chain Part 9 = Bolt Part 10 = Nut Nut is part of Bolt. The Bolt and Nut combo exists directly within Bicycle and within Gears which is part of Bicycle. In relation to what method to use I have looked at Adjacency, Edges, Enum Paths, Closures, DAGS(networks) and the Nested Set Model. I am still trying to work out what is what, but this is an extremely complex component database where there are multiple parents and any modification to a sub-tree must propogate through the other trees. More importantly there will be insertions, deletions and tree views that I wish to avoid recursion during general use, even at the cost of database space and query time during entry.

• Lua class instance with nested tables

  - by Anonnobody

  Hello, Simple lua game with simple class like so: creature = class({ name = "MONSTER BADDY!", stats = { power = 10, agility = 10, endurance = 10, filters = {} }, other_things = ... }) creatureA = creature.new() creatureB = creature.new() creatureA.name = "Frank" creatureB.name = "Zappa" creatureA.stats.agility = 20 creatureB.stats.power = 12 -- blah blah blah Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table. Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic? Q2: How would you have each instance of creature have it's own stats table (and sub tables)? PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation. Thanks a bunch.

• Is it possible to preview arbitrary formats in Nautilus?

  - by alfC

  I recently found out that Nautilus (Ubuntu 12.04 at least) can show thumbnails of files of non-image formats, for example (data grapher) grace files (.agr) shows a small version of the graph contained in its data. Obviously, there some library or script that is processing the file, making the image, and allowing nautilus to show a small version of it. This made me think that in principle any file that potentially can be processed into an image can serve as a Nautilus thumbnail. For example, a .tex file (which can be converted to .pdf) or a gnuplot script can be displayed as a thumbnail when possible. In the case of .tex file, the correspoding .pdf can be created by the command pdflatex file.tex. The question is, how can I tell Nautilus to create a thumbnail for an arbitrary format and how do I specify the commands to do so within Nautilus?

• Select row data as ColumnName and Value

  - by Bobcat1506

  I have a history table and I need to select the values from this table in ColumnName, ColumnValue form. I am using SQL Server 2008 and I wasn’t sure if I could use the PIVOT function to accomplish this. Below is a simplified example of what I need to accomplish: This is what I have: The table’s schema is CREATE TABLE TABLE1 (ID INT PRIMARY KEY, NAME VARCHAR(50)) The “history” table’s schema is CREATE TABLE TABLE1_HISTORY( ID INT, NAME VARCHAR(50), TYPE VARCHAR(50), TRANSACTION_ID VARCHAR(50)) Here is the data from TABLE1_HISTORY ID NAME TYPE TRANSACTION_ID 1 Joe INSERT a 1 Bill UPDATE b 1 Bill DELETE c I need to extract the data from TABLE1_HISTORY into this format: TransactionId Type ColumnName ColumnValue a INSERT ID 1 a INSERT NAME Joe b UPDATE ID 1 b UPDATE NAME Bill c DELETE ID 1 c DELETE NAME Bill Other than upgrading to Enterprise Edition and leveraging the built in change tracking functionality, what is your suggestion for accomplishing this task?

• iPhone: Grouped tables and navigation controller issues

  - by Jack Griffiths

  Hi there, I've set up a grouped table on my app, and pushing to new views works fine. Except for one thing. The titles and stack layout are all weird. Here's the breakdown: I have two sections in my table. When I tap on the first row in the first section, it takes me to the correct view, but the title of the new view is the name of the first row in the second section of the table. In turn, the second row in the first section's title is the second row in the second section's title. If I tap on the second row in the second section of the root view table, the navigation button goes to the second row in the first section of the table. So here's a diagram of my table: Table Section 1 Row 1 Row 2 Row 3 Table Section 2 Row A Row B Row C So if I tap on row 3, the title of the pushed view is Row C. The navigation button tells me to go back to Row 3, then eventually ending up at the root view. Here's my implementation file pushing the views: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //CSS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"CSS"]) { CSSViewController *css = [[CSSViewController alloc] initWithNibName:@"CSSViewController" bundle:nil]; [css setTitle:@"CSS"]; [self.navigationController pushViewController:css animated:YES]; } //HTML if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"HTML"]) { HTMLViewController *html = [[HTMLViewController alloc] initWithNibName:@"HTMLViewController" bundle:nil]; [html setTitle:@"HTML"]; [self.navigationController pushViewController:html animated:YES]; } //JS if ([[arryClientSide objectAtIndex:indexPath.row] isEqual:@"JavaScript"]) { JSViewController *js = [[JSViewController alloc] initWithNibName:@"JSViewController" bundle:nil]; [js setTitle:@"JavaScript"]; [self.navigationController pushViewController:js animated:YES]; } //PHP if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"PHP"]) { PHPViewController *php = [[PHPViewController alloc] initWithNibName:@"PHPViewController" bundle:nil]; [php setTitle:@"PHP"]; [self.navigationController pushViewController:php animated:YES]; } //SQL if ([[arryServerSide objectAtIndex:indexPath.row] isEqual:@"SQL"]) { SQLViewController *sql = [[SQLViewController alloc] initWithNibName:@"SQLViewController" bundle:nil]; [sql setTitle:@"SQL"]; [self.navigationController pushViewController:sql animated:YES]; } & the array feeding the table's data: - (void)viewDidLoad { [super viewDidLoad]; arryClientSide = [[NSArray alloc] initWithObjects:@"CSS",@"HTML",@"JavaScript",nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Objective-C", @"PHP",@"SQL",nil]; // arryResources = [[NSArray alloc] initWithObjects:@"HTML Colour Codes", @"Useful Resources", @"About",nil]; self.title = @"Select a Language"; [super viewDidLoad]; // Uncomment the following line to display an Edit button in the navigation bar for this view controller. // self.navigationItem.rightBarButtonItem = self.editButtonItem; } Any help would be greatly appreciated.

• Java: file write on finalize method

  - by sowrov

  In my understanding a singleton object will destroy only when the application is about to terminate. So in C++ I write a Singleton class to log my application and in that Singleton logger's destructor I log the time when my application was terminated. Things worked perfectly in C++. Now I want to have that same logger in Java, as in java there is no destructor so I implemented the finalize method for that singleton logger. But it seem that finalize method actually never get called. So, I add that System.runFinalizersOnExit(true); line, somewhere in my code (though I know it is deprecated) and that finalize method get called every time before termination of the app. But still there is a problem! If I try to write anything on file in that finalize method, It does not work, though System.out work without any problem! :( Can you guys help me on this problem? Here is a sample code of what I am try to do: Singleton Logger Class: public class MyLogger { FileWriter writer; private MyLogger() { try { this.writer = new FileWriter("log.txt"); } catch (IOException ex) { } } public static MyLogger getInstance() { return MyLoggerHolder.INSTANCE; } private static class MyLoggerHolder { private static final MyLogger INSTANCE = new MyLogger(); } @Override protected void finalize () { try { super.finalize(); System.out.println("Here"); //worked correctly. this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write("End"); this.writer.flush(); //does not work! this.writer.close(); } catch (Throwable ex) { } } public synchronized void log(String str) { try { this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write(str+"\n"); this.writer.flush(); } catch (IOException ex) { } } } Main: public class Main { public static void main(String[] args) { System.runFinalizersOnExit(true); MyLogger logger = MyLogger.getInstance(); logger.log("test"); } }

• mysql update too slow when joining multiple tables

  - by user293487

  Hi, I have two tables. they looks like as follows: Id (int) Tags char(128). the column Tags in table A does not have value. It is empty. The column Tags in table B has value. What I want to copy the Tags in table B to corresponding place of table A. the mapping is based on Id. My sql query is: update A INNER JOIN B set A.Tags = B.Tags where A.Id = B.Id There are about 2,000,000 rows in table A, and 50,000 rows in table B. The update seems very slow.... Could anyone tell me how to make it run faster?

• Do MySQL Locked Tables affect related Views?

  - by CogitoErgoSum

  So after reading http://stackoverflow.com/questions/1415602/performance-in-pdo-php-mysql-transaction-versus-direct-execution in regards to performance issues I was thinking about I did some research on locking tables in MySQL. On http://dev.mysql.com/doc/refman/5.0/en/table-locking.html Table locking enables many sessions to read from a table at the same time, but if a session wants to write to a table, it must first get exclusive access. During the update, all other sessions that want to access this particular table must wait until the update is done. This part struck me particularly becuase most of our queries will be updates rather than inserts. I was wondering if one created a table called foo on which all updates/inserts were carried out and then a view called foo_view (A copy of foo, or perhaps foo and a linkage of several other tables plus foo) on which all selects occured, would this locking issue still occur? That is, would SELECT quries on foo_view still have to wait for an update to finish on foo?

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• AJAX spreadsheet editor interfaced to own website

  - by Ole Tange

  My website has records that are tables. I would like for my users to be able to edit these records in an easy way. Currently they download a .csv-file, edit it in their favourite spreadsheet, and upload it again. But this often fails (they upload in wrong format or edit fields that they are not supposed to touch). I would therefore like to present the users with an editor directly on the website. So just like you can have WYSIWYG editors in CMSes for text I would like to have it for spreadsheets. One solution would be to interface my website with GoogleDoc and have the users edit the files using GoogleDoc's spreadsheet, and some how get the sheet back when they are done, but I do not know if this is possible at all.

• send multiple file over TCP with C# using TcpClient

  - by xnoor

  I'm trying to send multiple files over TCP using C# TcpClient, for a single file it works great, but when I have multiple files, it sends only the first one. Here is my code: SENDING FILES try { TcpClient tcpClient = new TcpClient(); NetworkStream networkStream; FileStream fileStream = null; tcpClient.Connect(appUpdateMessage.receiverIpAddress, 12000); networkStream = tcpClient.GetStream(); byte[] byteSend = new byte[tcpClient.ReceiveBufferSize]; string startupPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6); DirectoryInfo directoriesInfo = new DirectoryInfo(startupPath); DirectoryInfo[] directories = directoriesInfo.GetDirectories(); FileInfo[] files = directoriesInfo.GetFiles(); for (int iLoop = 0; iLoop < directories.Length; iLoop++) { FileInfo[] subdirectoryFiles = directories[iLoop].GetFiles(); foreach (FileInfo fi in subdirectoryFiles) { fileStream = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read); BinaryReader binFile = new BinaryReader(fileStream); FileUpdateMessage fileUpdateMessage = new FileUpdateMessage(); fileUpdateMessage.fileName = fi.Name; fileUpdateMessage.fileSize = fi.Length; fileUpdateMessage.targetDirectory = fi.Directory.Name; MessageContainer messageContainer = new MessageContainer(); messageContainer.messageType = MessageType.FileProperties; messageContainer.messageContnet = SerializationManager.XmlFormatterObjectToByteArray(fileUpdateMessage); byte[] messageByte = SerializationManager.XmlFormatterObjectToByteArray(messageContainer); networkStream.Write(messageByte, 0, messageByte.Length); int bytesSize = 0; byte[] downBuffer = new byte[2048]; while ((bytesSize = fileStream.Read(downBuffer, 0, downBuffer.Length)) > 0) { networkStream.Write(downBuffer, 0, bytesSize); } fileStream.Close(); } } tcpClient.Close(); networkStream.Close(); return true; } catch (Exception ex) { //logger.Info(ex.Message); return false; } finally { } RECEIVING FILES try { TcpClient tcpClient = c as TcpClient; NetworkStream networkstream = tcpClient.GetStream(); FileStream fileStream = null; byte[] _data = new byte[1024]; int _bytesRead = 0; _bytesRead = networkstream.Read(_data, 0, _data.Length); MessageContainer messageContainer = new MessageContainer(); messageContainer = SerializationManager.XmlFormatterByteArrayToObject(_data, messageContainer) as MessageContainer; switch (messageContainer.messageType) { case MessageType.FileProperties: FileUpdateMessage fileUpdateMessage = new FileUpdateMessage(); fileUpdateMessage = SerializationManager.XmlFormatterByteArrayToObject(messageContainer.messageContnet, fileUpdateMessage) as FileUpdateMessage; string startupPath = @"d:updatefolder";//System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6); DirectoryInfo mainDirectory = new DirectoryInfo(startupPath); DirectoryInfo targetDirecotry = new DirectoryInfo(startupPath + "\\" + fileUpdateMessage.targetDirectory); if (!targetDirecotry.Exists) { mainDirectory.CreateSubdirectory(fileUpdateMessage.targetDirectory); } fileStream = new FileStream(startupPath + "\\" + fileUpdateMessage.targetDirectory + "\\" + fileUpdateMessage.fileName, FileMode.Create, FileAccess.Write, FileShare.ReadWrite); long filezie = fileUpdateMessage.fileSize; int byteSize = 0; byte[] downBuffer = new byte[2048]; while ((byteSize = networkstream.Read(downBuffer, 0, downBuffer.Length)) > 0) { fileStream.Write(downBuffer, 0, byteSize); if (this.InvokeRequired) { this.Invoke((MethodInvoker)delegate { //progressBar1.Value = Convert.ToInt32((byteSize * 100) / fileUpdateMessage.fileSize); progressBar1.Value = Convert.ToInt32((fileStream.Length * 100) / fileUpdateMessage.fileSize); lblFileName.Text = fileUpdateMessage.fileName; }); } else { //progressBar1.Value = Convert.ToInt32((byteSize * 100) / fileUpdateMessage.fileSize); lblFileName.Text = fileUpdateMessage.fileName; } } fileStream.Close(); networkstream.Close(); break; } } catch (Exception ex) { //logger.Error(ex.Message); } Any idea what I am doing wrong?

• Webclient using download file to grab file from server - handling exceptions

  - by baron

  Hello everyone, I have a web service in which I am manipulating POST and GET methods to facilitate upload / download functionality for some files in a client/server style architecture. Basically the user is able to click a button to download a specific file, make some changes in the app, then click upload button to send it back. Problem I am having is with the download. Say the user expects 3 files 1.txt, 2.txt and 3.txt. Except 2.txt does not exist on the server. So I have code like (on server side): public class HttpHandler : IHttpHandler { public void ProcessRequest { if (context.Request.HttpMethod == "GET") { GoGetIt(context) } } private static void GoGetIt(HttpContext context) { var fileInfoOfWhereTheFileShouldBe = new FileInfo(......); if (!fileInfoOfWhereTheFileShouldBe.RefreshExists()) { throw new Exception("Oh dear the file doesn't exist"); } ... So the problem I have is that when I run the application, and I use a WebClient on client side to use DownloadFile method which then uses the code I have above, I get: WebException was unhandled: The remote server returned an error: (500) Internal Server Error. (While debugging) If I attach to the browser and use http://localhost:xxx/1.txt I can step through server side code and throw the exception as intended. So I guess I'm wondering how I can handle the internal server error on the client side properly so I can return something meaningful like "File doesn't exist". One thought was to use a try catch around the WebClient.DownloadFile(address, filename) method but i'm not sure thats the only error that will occur i.e. the file doesn't exist.

• input type file alternative and file upload best practice

  - by Ioxp

  Background: I am working on a file upload page that will extend an existing web portal. This page will allow for an end user to upload files from there local computer to our network (the files will not be stored on the web server, rather a remote workstation). The end user will have the ability to view the data that they have submitted by hyper-linking the files that have been uploaded on this page. Question 1: Is there an ASP.net alternative to the <input type="file" runat="server" /> HTML tag? The reason for asking is i would rather use an image button and display the file as an asp label on the portal to keep with a consistent style. Question 2: So i understand that giving the end user the ability to upload files to the server and then turn around to show them the data that they posted poses a security threat. So far i am using the id.PostedFile.ContentType and the file extension to reject the data if its not an accepted format (i.e. "text/plain", "application/pdf", "application/vnd.ms-excel", or "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"). Also the location where the files are uploaded to has a sufficient amount of virus and malware protection and this is not a concern. What, from the C# point of view, additional steps should i take to ensure that the end user cant take advantage and compromise the system in regards to allowing them to upload files?

• What file format can represent an uncompressed raster image at 48 or 64 bits per pixel?

  - by finnw

  I am creating screenshots under Windows and using the LockBits function from GDI+ to extract the pixel data, which will then be written to a file. To maximise performance I am also: Using the same PixelFormat as the source bitmap, to avoid format conversion Using the ImageLockModeUserInputBuf flag to extract the pixel data into a pre-allocated buffer This pre-allocated buffer (pointed to by BitmapData::Scan0) is part of a memory-mapped file (to avoid copying the pixel data again.) I will also be writing the code that reads the file, so I can use (or invent) any format I wish. However I would prefer to use a well-known format that existing programs (ideally web browsers) are able to read, because that means I can visually confirm that the images are correct before writing the code for the other program (that reads the image.) I have implemented this successfully for the PixelFormat32bppRGB format, which matches the format of a 32bpp BMP file, so if I extract the pixel data directly into the memory-mapped BMP file and prefix it with a BMP header I get a valid BMP image file that can be opened in Paint and most browsers. Unfortunately one of the machines I am testing on returns pixels in PixelFormat64bppPARGB format (presumably this is influenced by the video adapter driver) and there is no corresponding BMP pixel format for this. Converting to a 16, 24 or 32bpp BMP format slows the program down considerably (as well as being lossy) so I am looking for a file format that can use this pixel format without conversion, so I can extract directly into the memory-mapped file as I have done with the 32bpp format. What raster image file formats support 48bpp and/or 64bpp?

• Display a input type=file over another input type=file

  - by Kevin Sedgley

  WARNING: Lengthy description coming up! I have written an uploader based upon APC progress uploader for PHP. This works fine and dandy, but the script as a whole (apc etc) is intended to be used only for those with Javascript. To achieve this, I have searched for any input type=file, and replaced these with an absolutely positioned form that appears over the original area where the old file input area was. The reasons for this are so the new uploader can submit to a hidden in page IFrame has to be in a seperate <form> in order to submit to the APC reciever to display the progress upload bar. allows it to be used within any form with an input type=file throughout the site I have used JQuery to do this, with the following code: Original HTML form code: <div><input type="file" name="media" id="media" /></div> Find position of div block code: // get the parent div, and properties thereof parentDiv = $(this).closest('div'); w = $(parentDiv).width(); h = $(parentDiv).height(); loc = $(parentDiv).offset(); Locate new block over old block: $('#_sender').appendTo('body').css({left:loc.left,top:loc.top,position:'absolute',zIndex:400,height:h,width:w}).show(); This works fine, and shows over the old block OK. The problem: When other elements in the DOM before or above it change (in this case a "tree view" selector is pushing the old block down) the new upload form gets moved over other elements. Is there a JQuery (or JS) method for changing this upon DOM change? Some kind of .onchange for the page?! Or an .onmove for the original block? Thanks in advance you lovely people Before DOM change: . After: .

• Create Folders from text file and place dummy file in them using a CustomAction

  - by Birkoff

  I want my msi installer to generate a set of folders in a particular location and put a dummy file in each directory. Currently I have the following CustomActions: <CustomAction Id="SMC_SetPathToCmd" Property="Cmd" Value="[SystemFolder]cmd.exe"/> <CustomAction Id="SMC_GenerateMovieFolders" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (echo %a)" /> <CustomAction Id="SMC_CopyDummyMedia" Property="Cmd" ExeCommand="for /f &quot;tokens=* delims= &quot; %a in ([MBSAMPLECOLLECTIONS]movies.txt) do (copy [MBSAMPLECOLLECTIONS]dummy.avi &quot;%a&quot;\&quot;%a&quot;.avi)" /> These are called in the InstallExecuteSequence: <Custom Action="SMC_SetPathToCmd" After="InstallFinalize"/> <Custom Action="SMC_GenerateMovieFolders" After="SMC_SetPathToCmd"/> <Custom Action="SMC_CopyDummyMedia" After="SMC_GenerateMovieFolders"/> The custom actions seem to start, but only a blank command prompt window is shown and the directories are not generated. The files needed for the customaction are copied to the correct directory: <Directory Id="WIX_DIR_COMMON_VIDEO"> <Directory Id="MBSAMPLECOLLECTIONS" Name="MB Sample Collections" /> </Directory> <DirectoryRef Id="MBSAMPLECOLLECTIONS"> <Component Id="SampleCollections" Guid="C481566D-4CA8-4b10-B08D-EF29ACDC10B5" DiskId="1"> <File Id="movies.txt" Name="movies.txt" Source="SampleCollections\movies.txt" Checksum="no" /> <File Id="series.txt" Name="series.txt" Source="SampleCollections\series.txt" Checksum="no" /> <File Id="dummy.avi" Name="dummy.avi" Source="SampleCollections\dummy.avi" Checksum="no" /> </Component> </DirectoryRef> What's wrong with these Custom Actions or is there a simpler way to do this?

• Control pdb file output from build defintion file

  Hello, I am trying to generate a release build with no pdb files generated. I have seen numerous posts that suggest right-clicking on the project, selecting Properties, going to the Build tab and then to the Advanced... butoon and changing Debug Info to none. This works and all, but I need to do this for a build of ~50 solutions which contain ~25 projects each! Other posts mention editing the appropriate .csproj file, but again, with so many projects, this would take a long time. Is there any way to achieve this via the TFSBuild.proj file? I have tried adding the following to the TFSBuild.proj file, with no luck. <PropertyGroup> <Configuration>Release</Configuration> <Platform>AnyCPU</Platform> </PropertyGroup> <PropertyGroup> <DebugSymbols>false</DebugSymbols> <DebugType>none</DebugType> <Optimize>true</Optimize> </PropertyGroup> The following line prints out Release|AnyCPU, none, and false, but I still see .pdb file in the $(OutputDir) folder. <Message Text="$Configuration|Platform): $(Configuration)|$(Platform)" /> <Message Text="DebugType is: $(DebugType)"/> <Message Text="DebugSymbols is: $(DebugSymbols)"/> Thanks in advance, Urvi

• Define a swig interface file for generation of wrapper to every type from some header file

  - by Dmitriy Matveev

  Hi! We're using some C library in our Java project. Several years ago some other developer which has retired few years ago (as always) has created all the wrappers for us. The wrappers were generated by the swig, but the interface file is lost now. The basic idea of library and the wrappers for it is following: There only one function which returns pointer to some complex object. And there are wrapper for that function. The complex object is a tree-like structure with dozens of node kinds and types (C structures) used to represent them. There are hundreds of wrappers for every field of every type and we're trying to use them all. The library was updated some time ago and now there are some new data we unaware of which yet, but would like to use. This data is contained in some of the objects indirectly contained or referenced from the object created by the function we call (Some new fields and types were added). I know that I shouldn't make any changes to the wrappers by hand and should rather modify the interface, but as I already wrote it's missing. For now I only want to generate wrappers some few types which are added/changed and them to our old wrappers, but later I want to start creation of interface file which will define "what and how should be wrapped". All the definitions necessary for us are defined in single header file. Is it possible to tell swig to generate wrappers for every type in this header? If so, how can I write such interface file?

• Handling file uploads with JavaScript and Google Gears, is there a better solution?

  - by gnarf

  So - I've been using this method of file uploading for a bit, but it seems that Google Gears has poor support for the newer browsers that implement the HTML5 specs. I've heard the word deprecated floating around a few channels, so I'm looking for a replacement that can accomplish the following tasks, and support the new browsers. I can always fall back to gears / standard file POST's but these following items make my process much simpler: Users MUST to be able to select multiple files for uploading in the dialog. I MUST be able to receive status updates on the transmission of a file. (progress bars) I would like to be able to use PUT requests instead of POST I would like to be able to easily attach these events to existing HTML elements using JavaScript. I.E. the File Selection should be triggered on a <button> click. I would like to be able to control response/request parameters easily using JavaScript. I'm not sure if the new HTML5 browsers have support for the desktop/request objects gears uses, or if there is a flash uploader that has these features that I am missing in my google searches. An example of uploading code using gears: // select some files: var desktop = google.gears.factory.create('beta.desktop'); desktop.openFiles(selectFilesCallback); function selectFilesCallback(files) { $.each(files,function(k,file) { // this code actually goes through a queue, and creates some status bars // but it is unimportant to show here... sendFile(file); }); } function sendFile(file) { google.gears.factory.create('beta.httprequest'); request.open('PUT', upl.url); request.setRequestHeader('filename', file.name); request.upload.onprogress = function(e) { // gives me % status updates... allows e.loaded/e.total }; request.onreadystatechange = function() { if (request.readyState == 4) { // completed the upload! } }; request.send(file.blob); return request; } Edit: apparently flash isn't capable of using PUT requests, so I have changed it to a "like" instead of a "must".

• using ini file in vb6, problem with path to file

  - by DrPut

  I have read many articles about how to use an INI file within my VB6 project. I don't have a problem with the methods, my problem is how to make the EXE file find the INI file. I don't want to hard code the path in the program. I simply want the EXE to expect the INI file to be present in the same folder the EXE is executed from. When I run the program from inside VB6 IDE, the INI is found and processed. When I compile the program and run the EXE, nothing is found. My code looks like: gServer = sGetINI(sINIFile, "TOOLBOM", "ServerName", "?") where TOOLBOM is the [Section] and "ServerName" is the key for the value. I obtained the following code for the API: Rem API DECLARATIONS Declare Function GetPrivateProfileString Lib "kernel32" Alias _ "GetPrivateProfileStringA" (ByVal lpApplicationName _ As String, ByVal lpKeyName As Any, ByVal lpDefault _ As String, ByVal lpReturnedString As String, ByVal _ nSize As Long, ByVal lpFileName As String) As Long Declare Function WritePrivateProfileString Lib "kernel32" Alias _ "WritePrivateProfileStringA" (ByVal lpApplicationName _ As String, ByVal lpKeyName As Any, ByVal lpString As Any, _ ByVal lpFileName As String) As Long Public Function sGetINI(sINIFile As String, sSection As String, sKey _ As String, sDefault As String) As String Dim sTemp As String * 256 Dim nLength As Integer sTemp = Space$(256) nLength = GetPrivateProfileString(sSection, sKey, sDefault, sTemp, _ 255, sINIFile) sGetINI = Left$(sTemp, nLength) End Function Public Sub writeINI(sINIFile As String, sSection As String, sKey _ As String, sValue As String) Dim n As Integer Dim sTemp As String sTemp = sValue Rem Replace any CR/LF characters with spaces For n = 1 To Len(sValue) If Mid$(sValue, n, 1) = vbCr Or Mid$(sValue, n, 1) = vbLf _ Then Mid$(sValue, n) = " " Next n n = WritePrivateProfileString(sSection, sKey, sTemp, sINIFile) End Sub

• Is it possible to specify Jquery File Upload to post back only once (for multiple files)?

  - by JaJ

  When I upload multiple files (per bluimp jquery file upload) the [httppost] action is entered once per file. Is it possible to specify one and only one postback with an enumerated file container to iterate?

• Windows 2003 R2 zip program blocking EXE file

  - by Harvey Kwok

  I have a Windows 2003 R2 Enterprise Edition SP2 32-bit machine with all latest patch (as of 1-6-2011). It's a VM. I have a zip file, including a pdf file, a txt file and a exe file. If I copy the zip file onto the machine via a shared network drive, I can unzip all the files properly without problems. If I put the zip file on my web server and then I download it from there, I can only unzip the pdf file and txt file. The exe file is silently ignored. I searched the web and found somebody reporting similar issue on XP. If I right click on the zip file downloaded from the web server, at the bottom of the general page, it has a warning message saying that "This file came from antoher computer and might be blocked to help protect this computer" I understand that I can solve the problem by simply clicking the "Unblock" button and extract the file again. The things that bothering me is that why the warning message says "might be blocked"? I tried downloading the same zip file from the same web server on to my Windows 7 box with latest patch. It also shows the same warning message. However, even with the warning message, I can extract all the files properly without clicking the "Unblock" button. Is it a bug in Windows 2003 R2 SP1? Is there any security settings controlling this? How likely will the end user seeing this problem? I want to dig into this because I am worrying people downloading my zip file from my web server might see similar problems. The first thought coming to the user's mind will be the zip file is somehow corrupted. Honestly, I didn't know this "Unblock" feature in Windows before I run into this problem. EDIT I just tried it on another Windows 2003 R2 SP1 machine. The zip program doesn't block the EXE file on that machine either. Both Windows 2003 R2 SP1 machines are joining to the same forest.
