  • Creating secure .exe files in C#

    - by George
    Hi, I have heard some mutterings about C# being quite easy to "crack" and/or reverse engineer. Is this the case and if so, how can I go about preventing this, if possible ? Or at least making it more difficult ? Thanks, George.

  • Split a complex GUI window into several files in Netbeans

    - by Hectoret
    After building the application GUI, I realised it was a little bit too complex and I could reuse some of the Swing components. The result is a complex class with many anidated JPanels. My question is: does Netbeans provide a way to split a JPanel and its children components into a different class? If I do it by hand, will the GUI designer still work? Thanks!

  • Apache mod_rewrite - prefer files over directories with pretty URLs

    - by Jesse
    I want to have pretty urls so http://www.domain.com/foo will return http://www.domain.com/foo.php The issue is that there is a directory that has the same name. I have another page at http://www.domain.com/foo/bar/baz and right now my server just returns the directory listing of foo when I request http://www.domain.com/foo Pseudocode: If the request plus ".php" is a file rewrite out the file instead of the directory Actual Code: RewriteEngine On RewriteBase / RewriteCond %{SCRIPT_FILENAME}\.php -f RewriteRule (.*) $1.php [NC,L]

  • Improve performance of sorting files by extension

    - by DxCK
    With a given array of file names, the most simpliest way to sort it by file extension is like this: Array.Sort(fileNames, (x, y) => Path.GetExtension(x).CompareTo(Path.GetExtension(y))); The problem is that on very long list (~800k) it takes very long to sort, while sorting by the whole file name is faster for a couple of seconds! Theoretical, there is a way to optimize it: instead of using Path.GetExtension() and compare the newly created extension-only-strings, we can provide a Comparison than compares starting from the LastIndexOf('.') without creating new strings. Now, suppose i found the LastIndexOf('.'), i want to reuse native .NET's StringComparer and apply it only to the part on string after the LastIndexOf('.'). Didn't found a way to do that. Any ideas?

  • How to add new object to an IList mapped as a one-to-many with NHibernate?

    - by Jørn Schou-Rode
    My model contains a class Section which has an ordered list of Statics that are part of this section. Leaving all the other properties out, the implementation of the model looks like this: public class Section { public virtual int Id { get; private set; } public virtual IList<Static> Statics { get; private set; } } public class Static { public virtual int Id { get; private set; } } In the database, the relationship is implemented as a one-to-many, where the table Static has a foreign key pointing to Section and an integer column Position to store its index position in the list it is part of. The mapping is done in Fluent NHibernate like this: public SectionMap() { Id(x => x.Id); HasMany(x => x.Statics).Cascade.All().LazyLoad() .AsList(x => x.WithColumn("Position")); } public StaticMap() { Id(x => x.Id); References(x => x.Section); } Now I am able to load existing Statics, and I am also able to update the details of those. However, I cannot seem to find a way to add new Statics to a Section, and have this change persisted to the database. I have tried several combinations of: mySection.Statics.Add(myStatic) session.Update(mySection) session.Save(myStatic) but the closest I have gotten (using the first two statements), is to an SQL exception reading: "Cannot insert the value NULL into column 'Position'". Clearly an INSERT is attempted here, but NHibernate does not seem to automatically append the index position to the SQL statement. What am I doing wrong? Am I missing something in my mappings? Do I need to expose the Position column as a property and assign a value to it myself? EDIT: Apparently everything works as expected, if I remove the NOT NULL constraint on the Static.Position column in the database. I guess NHibernate makes the insert and immediatly after updates the row with a Position value. While this is an anwers to the question, I am not sure if it is the best one. I would prefer the Position column to be not nullable, so I still hope there is some way to make NHibernate provide a value for that column directly in the INSERT statement. Thus, the question is still open. Any other solutions?

  • Sending files using Winsock - optimal send() data length?

    - by Meta
    I am using Winsock with non-blocking sockets to send a file to a client. The way I'm doing it right now is that I read a chunk of 8192 bytes from the file, and then loop until all of it successfully goes through send() (obviously handling WSAEWOULDBLOCK as it occurs). I then move on and read the next 8192 bytes, and so on... Although I can use any other number than 8192 when I test the transfer on my local machine, once I try it over a network, it seems like 8191 is the largest number I can use. When I try to use any number higher than 8191 (starting with 8192), the file transfer becomes extremely slow (about 5 times slower). Is there any reason why 8191 is so special? I've done some more testing and it turns out that using 8000 is slightly faster (by 0.5%). If you understand why 8191 is so special, can you tell me if there is a number better than the others (better than 8000)? I have a feeling that it has something to do with the fact that the default send buffer allocated to the socket by Winsock is 8KB, but I don't understand why. It might also have something to do with the Nagle algorithm, but again, I'm not sure how. Note that I have not modified the SO_SNDBUF option nor the TCP_NODELAY option. Or am I doing this all wrong? What's the best way of sending a file over a non-blocking socket?

  • Interop Structure: Should Unsigned Short be Mapped to byte[]?

    - by Ngu Soon Hui
    I have such a C++ structure: typedef struct _FILE_OP_BLOCK { unsigned short fid; // objective file ID unsigned short offset; // operating offset unsigned char len; // buffer length(update) // read length(read) unsigned char buff[MAX_BUFF_SIZE]; } FILE_OP_BLOCK; And now I want to map it in .Net. The tricky thing is that the I should pass a 2 byte array for fid, and integer for len, even though in C# fid is an unsigned short and len is an unsigned char I wonder whether my structure ( in C#) below is correct? public struct File_OP_Block { [MarshalAs(UnmanagedType.ByValArray, SizeConst = 2)] public byte[] fid; public ushort offset; public byte length; [MarshalAs(UnmanagedType.ByValArray, SizeConst = 240)] public char[] buff; }

  • Web development - relative URLs without duplicating files

    - by eshriek
    I have a site with index.php in the root folder, images in /img , and overview.php in /content . I have a sidebar.php file that is included in both index.php and overview.php . How should I refer to /img/image.gif if I include a link in each file? The location of image.gif changes relative to the location of the file that references it. Using /img/image.gif in sidebar.php will work in index.php, but it fails for the file located at /content/overview.php. The only solution that I can see is to either include a seperate sidebar.php in each subdirectory, or include an /img directory in every sub-directory. The best suggestion that I can find is to use the <base html tag as suggested here: Change relative link paths for included content in PHP However, in the same link, SamGoody suggests that the <base tag "is no longer properly supported in Internet Explorer, since version 7." I'd like some insight on the matter before committing to a course of action. Thanks. EDIT: I am using the wrong approach below with "../" Example- root/index.php: ... <link rel="stylesheet" type="text/css" href="style.css" /> <title>title</title> </head> <body> <?php include('include/header.php'); ?> <?php include('include/menu.php'); ?> ... root/include/header.php: ... <div id="header"> <span class="fl"><img src="img/dun1.png"/></span><span class="fr"><img src="img/dun2.png"/></span> ... root/content/overview.php: ... <link rel="stylesheet" type="text/css" href="../style.css" media="screen" /> <title>Overview</title> </head> <body> <?php include('../include/header.php'); ?> <?php include('../include/menu.php'); ?> ...

  • FDF-files not opening properly

    - by Flyhard
    We have created a servlet that provides a FDF file for our clients. The FDF file is created by iText and the output looks fine. Whenever we open the FDF either from the Servlet, or from a local file, AcrobatReader starts, asks if the PDF should be downloaded, we allow that and then we see the PDF - without the values we filled in the form. One thing that seems strange is, that regardless of the Browser, we get prompted about what to do with the PDF file that Adobe has tried to load. Anything else that clicking "open" will result in a empty Acrobat viewer window. I suspect that Acrobat forgets what to do with the PDF - but I have run out of ideas. Anyone got an idea where to look further?

  • Where should I keep my log files?

    - by ripper234
    We keep most of our logs in a dedicated database table. We have written custom appenders for log4j and log4net, have a fixed log schema with lots of handy columns, and are quite happy with it. Is that the "best practice" (for sites smaller in scale than Facebook, where a simple DB table just won't scale)?

  • Access Profile Provider property values in ASPX files

    - by AsM
    We have several companies using one web application. Companies may decide to display different values in Labels. e.g. CompanyA - ZipCodeCaption = "Zip Code" CompanyB - ZipCodeCaption = "Pin Code" CompanyA - USDSymbolCaption = "USD" CompanyB - USDSymbolCaption = "$" We are using profile provider to store each company's settings. We would like to access these profile values in ASPX to assign values to Label's text properties just like Web Config app settings are accessed in aspx. e.g. " Is this possible? Is there a better way to go about doing this?

  • Create Excel files from C# without office

    - by tbischel
    I am writing a program that generates excel reports, currently using the Microsoft.Interop.Excel reference. My dev computer has Excel on it, but the end user may or may not have Office installed. Will this tool fail if Office isn't installed on the end users computer, or is this interop service separate from the actual application?

  • Error when loading YAML config files in Rails

    - by ZelluX
    I am configuring Rails with MongoDB, and find a strange problem when paring config/mongo.yml file. config/mongo.yml is generated by executing script/rails generate mongo_mapper:config, and it looks like following: defaults: &defaults host: 127.0.0.1 port: 27017 development: <<: *defaults database: tc_web_development test: <<: *defaults database: tc_web_test From the config file we can see the objects development and test should both have a database field. But when it is parsed and loaded in config/initializers/mongo.db, config = YAML::load(File.read(Rails.root.join('config/mongo.yml'))) puts config.inspect MongoMapper.setup(config, Rails.env) the strange thing comes: the output of puts config.inspect is {"defaults"=>{"host"=>"127.0.0.1", "port"=>27017}, "development"=>{"host"=>"127.0.0.1", "port"=>27017}, "test"=>{"host"=>"127.0.0.1", "port"=>27017}} which does not contain database attribute. But when I execute the same statements in a plain ruby console, instead of using rails console, mongo.yml is parsed in a right way. {"defaults"=>{"host"=>"127.0.0.1", "port"=>27017}, "development"=>{"host"=>"127.0.0.1", "port"=>27017, "database"=>"tc_web_development"}, "test"=>{"host"=>"127.0.0.1", "port"=>27017, "database"=>"tc_web_test"}} I am wondering what may be the cause of this problem. Any ideas? Thanks.

  • How to implement a download for dynamic files in asp.net with masterpages

    - by Tim
    Hello, the title says it all. I have seen some similar questions on SO like this or this, but either i have overlooked something or my requirement is different, neither works. My situation is following: i have a Masterpage one of its contentpage is called MasterData.aspx MasterData has an asp.net ajax tabcontainer control with one usercontrol in every tabpanel these usercontrols(f.e. MD_Customer.ascx)hold the main content(like a normal page) they all have GridViews in it and i want to provide an Excel-Export-Button What i've tried is is to use an iframe like here. But the function that adds the iframe to the document gets never called and therefore i never see the save-as-dialog. Maybe this is caused by using a MasterPage. Does somebody has an idea on how to provide a button in an UpdatePanel that causes an async postback, so that i can generate a CSV dynamically in codebehind and write it to the response? Thank you in advance. aspx-markup: <asp:UpdatePanel ID="UpdGridInfo" runat="server" > <ContentTemplate> <asp:Label ID="LblInfo" Font-Underline="false" runat="server" CssClass="content" ></asp:Label>&nbsp;&nbsp; <asp:ImageButton ToolTip="export to Excel" style="vertical-align:bottom" ID="BtnExcelExport" ImageUrl="~/images/excel2007logo.png" runat="server" /> </ContentTemplate> </asp:UpdatePanel> and the BtnExportExcel codebehind handler(of course it cannot work to write the csv to the response of this page): Private Sub BtnExcelExport_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles BtnExcelExport.Click Dim csv As String = tableToCsv(DirectCast(Me.GridSource, DataTable)) Response.AddHeader("Content-disposition", "attachment; filename=RuleConfigurationFile.csv") Response.ContentType = "application/octet-stream" Response.Write(csv) Response.End() End Sub

    I am trying to update my text file by matching the first column to another updated file's first column, after match it, it will update the old file.

Thanks!

  • app.config files of referenced dlls

    I have a Web Project (VS 2008) that references a bunch of DLLs. The DLLs are built separately, so the project references binaries and not DLL projects. Some of the DLLs have their own app.config, which I want to be copied autmatically to the web project's output directory. Is there any suitable generic way to achieve this?

  • Compare output of program to correct program using bash script, without using text files

    - by Doug
    I've been trying to compare the output of a program to known correct output by using a bash script without piping the output of the program to a file and then using diff on the output file and a correct output file. I've tried setting the variables to the output and correct output and I believe it's been successful but I can't get the string comparison to work correctly. I may be wrong about the variable setting so it could be that. What I've been writing: TEST=`./convert testdata.txt < somesampledata.txt` CORRECT="some correct output" if [ "$TEST"!="$CORRECT" ]; then echo "failed" fi

  • Generation of .tlb Files in Windows 7 Pro 32-bit

    - by aF
    I have a C++ DLL that imports a .tlb file generated in a C# project. The C++ DLL is a wrapper DLL containing functions that call the corresponding C# functions. When I call the C++ functions on the computer that I built the projects, all works well. But when I copy the DLL's and generated tlb's to another computer with the same exact version of Windows and installed programs andI call the C++ functions, it breaks with a COM error. However, after recompiling the projects on the new computer, everything works again. I already checked the "Work on All Computers" for both projects but this keeps happening. What else do I need to do for the DLL's to work on all computers?

  • VB.NET 2008, Windows 7 and saving files

    - by James Brauman
    Hello, We have to learn VB.NET for the semester, my experience lies mainly with C# - not that this should make a difference to this particular problem. I've used just about the most simple way to save a file using the .NET framework, but Windows 7 won't let me save the file anywhere (or anywhere that I have found yet). Here is the code I am using to save a text file. Dim dialog As FolderBrowserDialog = New FolderBrowserDialog() Dim saveLocation As String = dialog.SelectedPath ... Build up output string ... Try ' Try to write the file. My.Computer.FileSystem.WriteAllText(saveLocation, output, False) Catch PermissionEx As UnauthorizedAccessException ' We do not have permissions to save in this folder. MessageBox.Show("Do not have permissions to save file to the folder specified. Please try saving somewhere different.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) Catch Ex As Exception ' Catch any exceptions that occured when trying to write the file. MessageBox.Show("Writing the file was not successful.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) End Try The problem is that this using this code throws an UnauthorizedAccessException no matter where I try to save the file. I've tried running the .exe file as administrator, and the IDE as administrator. Is this just Windows 7 being overprotective? And if so, what can I do to solve this problem? The requirements state that I be able to save a file! Thanks.
