• Simple string encryption in .NET and Javascript

  - by jonathanconway

  I'm developing an ASP.NET MVC application in which I want to encrypt a short string on the server, using C#, and send it to the client-side. Then on the client-side it will be decrypted through Javascript code. Any thoughts on how to implement this? Do you know of a simple encryption algorithm (doesn't have to be bullet-proof secure) that can be easily translated from C# to Javascript or vice-versa? NOTE: I could do this entirely in C# and do the decryption through Ajax, but I'd prefer not to do it this way, as I want to reduce website traffic as much as possible.

• ASP.NET How expensive is it to call an Application Variable many times?

  - by Matias Nino

  The short of it is: Is it costly to check an Application Variable such as Application("WebAppName") more 10-20 times each time a page loads? Background: (feel free to critique) Some includes in my site contain many links and images which cannot use relative urls due to their inclusion in different paths. Hence these includes contain frequent instances of <img src="<%=Application("Webroot")%>images\image.gif"> Is it expensive to keep calling an Application variable like this? Should I just put the Application value in some local variable to use where needed? IMPORTANT NOTE: I need my webapp to run fine on a server whether it be in the root web ("/") or in a virtual subweb ("/app"). Thanks in advance for any wisdom shared.

• PHP urlencode() tacking on ?SID=xxx ... Why?

  - by retailevolved

  I am trying to output a simple link. This works great: $url = 'http://www.google.com'; echo $url; This doesn't work great: $url = 'http://www.google.com'; echo urlencode($url); The second example tacks on "?SID=xxx" to the end of the URL for some reason. How do I prevent this from happening? Note: The code to generate the URL has been changed to protect the innocent.

• How to determine Jet database Engine Type programmatically

  - by MZB

  I have a program which needs to upgrade any Access (Jet) database it opens to JET Version4.x if it isn't already that version. (This enables use of SQL-92 syntax features) Upgrading is (relatively) easy. A call to the JRO.JetEngine object's CompactDatabase method (as described here) should do the trick, but before I do this I need to determine whether an upgrade is required. How do I determine the Jet OLEDB:Engine Type of an existing database? Can this be determined from an open OleDBConnection? Note: I'm talking about database versions, not Jet library versions. C# or .Net solution greatly appreciated.

• SerialPort not taking input. It throws it back at me!

  - by Mashew

  When I try to write an AT command to my GSM modem, it does not seem to take the command. I have used PuTTY to check that the command words, it does. I have checked to see if the port is opening, it does. What could I possibly be doing wrong? NOTE: The "lol" part is for debugging purposes. ;3 SerialPort sp = new SerialPort("COM3"); sp.BaudRate = 9600; sp.DataBits = 8; sp.StopBits = StopBits.One; sp.Parity = Parity.None; sp.Open(); if (sp.IsOpen == false) { sp.Open(); } Thread.Sleep(1000); sp.WriteLine("AT+CMGF=1"); Thread.Sleep(1000); string lol = sp.ReadExisting(); sp.Close(); return lol;

• How do I consume a COM+ local server from C#?

  - by Mystere Man

  I have a web application from a company that has gone out of business. We're looking to extend the web app a bit with some asp.net functionality. The web app was written as an ISAPI application in Delphi, and uses COM+ to talk to the SQL Server and handles things like session management and authentication. So, in order to get the current user and other details, I have to use the undocument COM+ components. I was able to dig out the type library and auto generated IDL, but at this point i'm lost in creating a .NET proxy class for this. Is there a way to autogenerate the .net COM+ proxy either from the .dll itself (extracting the typelib info) or from the IDL? Note: These seem to be simple COM style objects hosted in COM+ servers, no subscriptions or transaction monitoring..

• How can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

  - by firoso

  Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.

• How to call regular JS function with params within jQuery ?

  - by Kim

  Is there another way to run a regular JS function with params passed than what I use below ? It seems redundant use a on-the-way function to do this. function regularJSfunc(param1,param2) { // do stuff } $(document).ready(function(){ $('#myId').change(function(){ regularJSfunc('data1','data2'); }); } Using a .bind event seems much better, however I am not sure how to access the params. Note: Example below doesnt work. $(document).ready(function(){ $('#myId').bind('change',{'data1','data2'},regularJSfunc); }

• Subversion: svn protocol with HTTP/HTTPS proxy

  - by Neeraj

  Hi all, I need to do a svn checkout,say svn checkout svn://XYZ.com/trunk. I am using the svn client from behind the proxy. I had accessed other repositries using the http protocol in past but with svn protocol,it fails with "Connection Refused", reason I think being the port not allowed by the proxy.Nonetheless, the HTTP protocol is not supported on the server. However, svn+ssh gets connected but it prompts for an account at that server which I don't have? Is there any way out other than requesting for an account? Note that I can't affect the settings of the proxy server.

• Ruby class instance variables and inheritance

  - by rlandster

  I have a Ruby class called LibraryItem. I want to associate with every instance of this class an array of attributes. This array is long and looks something like ['title', 'authors', 'location', ...] Note that these attributes are not really supposed to be methods, just a list of attributes that a LibraryItem has. Next, I want to make a subclass of LibraryItem called LibraryBook that has an array of attributes that includes all the attributes of LibraryItem but will also include many more. Eventually I will want several subclasses of LibraryItem each with their own version of the array @attributes but each adding on to LibraryItem's @attributes (e.g., LibraryBook, LibraryDVD, LibraryMap, etc.). So, here is my attempt: class LibraryItem < Object class << self; attr_accessor :attributes; end @attributes = ['title', 'authors', 'location',] end class LibraryBook < LibraryItem @attributes.push('ISBN', 'pages'] end This does not work. I get the error undefined method `push' for nil:NilClass

• Is it safe to catch an access violation in this scenario?

  - by Eloff

  I've read a lot, including here on SO that suggests this is a very bad idea in general and that the only thing you can do safely is exit the program. I'm not sure that this is true. This is for a pooling memory allocator that hands off large allocations to malloc. During pool_free() a pointer needs to be checked it it belongs to a pool or was allocated with malloc. By rounding the address down to the nearest 1MB boundary, I get a pointer to the beginning of a block of memory in the pool, or undefined if malloc was used. In the first case I can easily verify that the block of memory belongs to the pool, but, if it does not I will either fail this verification, or I will get an access violation (note that this is a read-only process). Could I not catch this with SEH (Windows) or handle the signal (POSIX) and simply treat it as a failed verification? (i.e. this is only possible if malloc was used, so pass the ptr to free())

• Program crashes in debugger before anything happens

  - by Tim

  I'm building an application for Windows XP using the MinGW tool chain and it sometimes crashes unexpectedly. So, I'm trying to use a debugger (Gdb) but the program exits with code 03 before anything happens. In fact, all I see from GDB is: [New thread 3184.0x7b8][New thread 3184.0xef8] Program exited with code 03. My suspicion is that there is some failed dynamic linking of a dependency (which are Qt, VTK, and ITK, all built with MinGW). However, this does not happen when I just run the program normally. Or if it happens, it appears to be intermittent and well after the program is launched and running. NOTE: I'm also using Cmake for cross compiling. What should I do? What can I try?

• .NET Framework - Possible memory-leaky classes?

  - by Robert Fraser

  Just the other day I was investigating a memory leak that was ballooning the app from ~50MB to ~130MB in under two minutes. Turns out that the problem was with the ConcurrentQueue class. Internally, the class stores a linked list of arrays. When an item is dequeued from the ConcurrentQueue, the index in the array is bumped, but the item remains in the array (i.e. it's not set to null). The entire array node is dropped after enough enqueues/dequeues, so it's not technically a leak, but if storing only a few large objects in the ConcurrentQueue, this can get out of hand fast. The documentation makes no note of this danger. I was wondering what other potential memory pitfalls are in the Base Class Library? I know about the Substring one (that is, if you call substring and just hold onto the result, the whole string will still be in memory). Any others you've encountered?

• Security sandbox violation when connecting to Socket from flex

  - by KensoDev

  Hi, I am using a Socket (not xmlSocket) connection between flex applications and the server pushing messages. Now, when I connect from the local machine to the server everything is working file and running, connection is succesful and I get data back and forth. When I upload the application (flex) to the server and run it from there, I get a security sandBox violation message. Note: 1. I do have a crossdomain file with * wildcard both on port and on domain. 2. I created a Securiy.allowDomain("*") as well. Another thing. I also created another listener on that same server, listening to connections for port 843 (default) and this service just waited for a connection send policy file to the client and that's it. That did not solve the problem as well... That's next? What should I do to fix the problem? Appreciate your help. Avi

• C#: Hook up all events from object in single statement.

  - by David

  In my domain layer all domain objects emit events (of type InvalidDomainObjectEventHandler) to indicate invalid state when the IsValid property is called. On an aspx codebehind, I have to manually wire up the events for the domain object like this: _purchaseOrder.AmountIsNull += new DomainObject.InvalidDomainObjectEventHandler(HandleDomainObjectEvent); _purchaseOrder.NoReason += new DomainObject.InvalidDomainObjectEventHandler(HandleDomainObjectEvent); _purchaseOrder.NoSupplier += new DomainObject.InvalidDomainObjectEventHandler(HandleDomainObjectEvent); _purchaseOrder.BothNewAndExistingSupplier += new DomainObject.InvalidDomainObjectEventHandler(HandleDomainObjectEvent); Note that the same method is called in each case since the InvalidDomainobjectEventArgs class contains the message to display. Is there any way I can write a single statement to wire up all events of type InvalidDomainObjectEventHandler in one go? Thanks David

• Bind Data to Multiple Labels From Multiple DataSources

  - by Steven

  I have two AccessDataSources each returning one row. I want to use the data in each row to populate content on my page, so I figured I would use a Repeater or FormView. However, I would not necessarily want the labels bound to a particular DataSource placed together. For example, I might want labels from the following columns in order (DataSourceName.ColumnName): TestSetup.TestType, TestSummary.FormattedValue, TestSetup.DeviceChannel, TestSummary.CompletedOn. How do I handle this? Do I just have a separate Repeater/FormView for each value? Can I have both Repeater's/FormView's in 'scope' at the same time? Note: No language preference (C#/VB).

• Creating combinations that have no more one intersecting element

  - by khuss

  I am looking to create a special type of combination in which no two sets have more than one intersecting element. Let me explain with an example: Let us say we have 9 letter set that contains A, B, C, D, E, F, G, H, and I If you create the standard non-repeating combinations of three letters you will have 9C3 sets. These will contain sets like ABC, ABD, BCD, etc. I am looking to create sets that have at the most only 1 common letter. So in this example, we will get following sets: ABC, ADG, AEI, AFH, BEH, BFG, BDI, CFI, CDH, CEG, DEF, and GHI - note that if you take any two sets there are no more than 1 repeating letter. What would be a good way to generate such sets? It should be scalable solution so that I can do it for a set of 1000 letters, with sub set size of 4. Any help is highly appreciated. Thanks

• minimum enclosing rectangle of fixed aspect ratio

  I have an Image with many rectangles at different positions in the image and of different sizes (both overlapping and non-overlapping). I also have a non-negative scores associated with each of these rectangles. My problem now is to find one larger rectangle *of a fixed (given) aspect ratio* that encloses as many of these rectangles as possible. I am looking for an algorithm to do this, if anyone has a solution, even a partial one it would be helpful. Please note that the positions of the rectangles in the image is fixed and cannot be moved around and there is no orientation issue as all of them are upright.

• Problem drawing a polygon on data clusters in MATLAB

  - by Hossein

  Hi, I have some data points which I have devided into them into some clusters with some clustering algorithms as the picture below:(it might takes some time for the image to appear) Each color represents different cluster. I have to draw polygons around each cluster. I use convhull for this reason. But as you can see the polygon for the red cluster is very big and covers a lot of areas, which is not the one I am looking for. I need to draw lines(ploygons) exactly around my data sets. For example in the picture above I want a polygon that is drawn exactly the same(and around) as the red cluster with the 3 branches. In other words, in this case I need a polygon with 3 branches to cover my red clusters not that big polygon that covers the whole area. Can anyone help me with this? Please Note that the solution should be general, because the clusters will change in each run of the algorithm, so it needs to be in a way that is general.
