• Lotus Notes rich text field to RTF File - VB

  - by user236105

  Here is my problem, I am doing a data migration from Lotus notes to another type of software that does not support Rich Text Fields. I am trying to write a VB 2005 program that will take any rich text fields that are found and place them into an RTF file - which will be uploaded as an attachment in the new software. I cannot get the program to take the rich text formating or objects to the RTF file, only the plain text. I have tried everything under the sun using the COM library to get these objects out to no avail. Any ideas or suggestions? Thank you in advance Bryan

• WIX will not add HKLM registry setting during Windows 7 install

  - by Scott Boettger

  Good Morning, I have written a WiX installer that works perfectly with Windows XP but when installing to a Windows 7 box I am running into difficulty with Registry Entries. What I need to do is add a HKLM entry as well as the registry entry for the program to show in the start menu. Here is the code i am using for both types of entry: <!-- Create the registry entries for the program --> <DirectoryRef Id="TARGETDIR"> <Component Id="RegistryEntriesInst" Guid="..."> <RegistryKey Root="HKLM" Key="Software\$(var.Manufacturer)\$(var.ProductName)" Action="createAndRemoveOnUninstall"> <RegistryValue Type="string" Name="installed" Value="true" KeyPath="yes"/> </RegistryKey> </Component> <Component Id="RegistryEntriesVer" Guid="..."> <RegistryKey Root="HKLM" Key="Software\$(var.Manufacturer)\$(var.ProductName)" Action="createAndRemoveOnUninstall"> <RegistryValue Type="string" Name="version" Value="$(var.ProductVersion)" KeyPath="yes"/> </RegistryKey> </Component> </DirectoryRef> <!-- To add shortcuts to the start menu to run and uninstall the program--> <DirectoryRef Id="ApplicationProgramsFolder"> <Component Id="ApplicationShortcut" Guid="..."> <Shortcut Id="ApplicationStartMenuShortcut" Name="$(var.ProductName)" Description="..." Target="[SERVERLOCATION]$(var.Project.TargetFileName)" WorkingDirectory="SERVERLOCATION"/> <Shortcut Id="UninstallProduct" Name="Uninstall $(var.ProductName)" Description="..." Target="[System64Folder]msiexec.exe" Arguments="/x [ProductCode]"/> <RemoveFolder Id="SERVERLOCATION" On="uninstall"/> <RegistryValue Root="HKCU" Key="Software\$(var.Manufacturer)\$(var.ProductName)" Name="installed" Type="integer" Value="1" KeyPath="yes"/> </Component> </DirectoryRef> Any help/suggestions that can be given will be appreciated. On a side note the registry permissions are the same on the XP and 7 computers. Thanks

• Hardware Emulator / Simulator for Winforms .Net Application

  - by Suneet

  I have a WinForms .Net HMI software which talks to hardware over USB. I check for communication with the hardware at Load time and if communication is active then run it (The hardware manufacturer has provided a communication library to talk over USB). I want to build an emulator for cases when communication with hardware is not possible (not connected) and want the software to run in simulated mode by providing dummy values for different states of hardware. Has anyone implemented something similar? Any pointers will be helpful. Are there any design patterns to handle such implementations. TIA

• Conflicting PACKAGE_NAME and other macros when using autotools.

  - by baol

  When using autotools (with a config.h file) for both a library and a software built on that library the compiler complains about a redefinition of some macros (PACKAGE_NAME, PACKAGE_TARNAME and so on). How can I prevent this? The config.h file is needed in the library to propagate it's setting to the software that use it. Right now I have a wrapper script library_config.h that includes the original config.h and provides defaults when the user is not using autotools, but even undefining the macros in that package I get the redefinition warning from gcc. #ifndef LIB_CONFIG_H #define LIB_CONFIG_H #ifdef HAVE_CONFIG_H # include "config.h" # undef PACKAGE # undef PACKAGE_BUGREPORT # undef PACKAGE_NAME # undef PACKAGE_STRING # undef PACKAGE_TARNAME # undef PACKAGE_VERSION # undef VERSION #else # if defined (WIN32) # define HAVE_UNORDERED_MAP 1 # define TR1_MIXED_NAMESPACE 1 # elif defined (__GXX_EXPERIMENTAL_CXX0X__) # define HAVE_UNORDERED_MAP 1 # else # define HAVE_TR1_UNORDERED_MAP 1 # endif #endif #endif I believe the best option would be to have a library without that macros: How can I avoid the definition of PACKAGE, PACKAGE_NAME and so on in the library when using autotools?

• Repairing malformatted html attributes using c#

  - by jhoefnagels

  I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>

• Does anyone know of a library in Java that can parse ESRI Shapefiles?

  - by KingNestor

  I'm interested in writing a visualization program for the road data in the 2009 Tiger/Line Shapefiles. I'd like to draw the line data to display all the roads for my county. The ESRI Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products.1 A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required. Does anyone know of existing libraries for parsing and reading in the line data for Shapefiles?

• PHP File unreadable after being downloaded

  - by Drew

  Hi I have a script that creates a file and stores it on the server. The file is encoded in UTF-8 and is a kind of xml file for the cmap software. If i open the file directly from the server then there is no problem and the file can be read. I am forcing a download of this file when a user goes to a specific url. After such a download, the file is unreadable by the cmap software. I have to go into my text editor (notepad++) and change the encoding from UTF-8 to UTF-8 without BOM. Am I sending the wrong headers? Is php doing something to the file when it is downloading it? Any advice on this would really be appreciated. Cheers Drew

• C#: Why Decorate When You Can Intercept

  - by James Michael Hare

  We've all heard of the old Decorator Design Pattern (here) or used it at one time or another either directly or indirectly.  A decorator is a class that wraps a given abstract class or interface and presents the same (or a superset) public interface but "decorated" with additional functionality.   As a really simplistic example, consider the System.IO.BufferedStream, it itself is a descendent of System.IO.Stream and wraps the given stream with buffering logic while still presenting System.IO.Stream's public interface:   1: Stream buffStream = new BufferedStream(rawStream); Now, let's take a look at a custom-code example.  Let's say that we have a class in our data access layer that retrieves a list of products from a database:  1: // a class that handles our CRUD operations for products 2: public class ProductDao 3: { 4: ... 5:  6: // a method that would retrieve all available products 7: public IEnumerable<Product> GetAvailableProducts() 8: { 9: var results = new List<Product>(); 10:  11: // must create the connection 12: using (var con = _factory.CreateConnection()) 13: { 14: con.ConnectionString = _productsConnectionString; 15: con.Open(); 16:  17: // create the command 18: using (var cmd = _factory.CreateCommand()) 19: { 20: cmd.Connection = con; 21: cmd.CommandText = _getAllProductsStoredProc; 22: cmd.CommandType = CommandType.StoredProcedure; 23:  24: // get a reader and pass back all results 25: using (var reader = cmd.ExecuteReader()) 26: { 27: while(reader.Read()) 28: { 29: results.Add(new Product 30: { 31: Name = reader["product_name"].ToString(), 32: ... 33: }); 34: } 35: } 36: } 37: }            38:  39: return results; 40: } 41: } Yes, you could use EF or any myriad other choices for this sort of thing, but the germaine point is that you have some operation that takes a non-trivial amount of time.  What if, during the production day I notice that my application is performing slowly and I want to see how much of that slowness is in the query versus my code.  Well, I could easily wrap the logic block in a System.Diagnostics.Stopwatch and log the results to log4net or other logging flavor of choice: 1:     // a class that handles our CRUD operations for products 2:     public class ProductDao 3:     { 4:         private static readonly ILog _log = LogManager.GetLogger(typeof(ProductDao)); 5:         ... 6:         7:         // a method that would retrieve all available products 8:         public IEnumerable<Product> GetAvailableProducts() 9:         { 10:             var results = new List<Product>(); 11:             var timer = Stopwatch.StartNew(); 12:             13:             // must create the connection 14:             using (var con = _factory.CreateConnection()) 15:             { 16:                 con.ConnectionString = _productsConnectionString; 17:                 18:                 // and all that other DB code... 19:                 ... 20:             } 21:             22:             timer.Stop(); 23:             24:             if (timer.ElapsedMilliseconds > 5000) 25:             { 26:                 _log.WarnFormat("Long query in GetAvailableProducts() took {0} ms", 27:                     timer.ElapsedMillseconds); 28:             } 29:             30:             return results; 31:         } 32:     } In my eye, this is very ugly.  It violates Single Responsibility Principle (SRP), which says that a class should only ever have one responsibility, where responsibility is often defined as a reason to change.  This class (and in particular this method) has two reasons to change: If the method of retrieving products changes. If the method of logging changes. Well, we could “simplify” this using the Decorator Design Pattern (here).  If we followed the pattern to the letter, we'd need to create a base decorator that implements the DAOs public interface and forwards to the wrapped instance.  So let's assume we break out the ProductDAO interface into IProductDAO using your refactoring tool of choice (Resharper is great for this). Now, ProductDao will implement IProductDao and get rid of all logging logic: 1:     public class ProductDao : IProductDao 2:     { 3:         // this reverts back to original version except for the interface added 4:     } 5:  And we create the base Decorator that also implements the interface and forwards all calls: 1:     public class ProductDaoDecorator : IProductDao 2:     { 3:         private readonly IProductDao _wrappedDao; 4:         5:         // constructor takes the dao to wrap 6:         public ProductDaoDecorator(IProductDao wrappedDao) 7:         { 8:             _wrappedDao = wrappedDao; 9:         } 10:         11:         ... 12:         13:         // and then all methods just forward their calls 14:         public IEnumerable<Product> GetAvailableProducts() 15:         { 16:             return _wrappedDao.GetAvailableProducts(); 17:         } 18:     } This defines our base decorator, then we can create decorators that add items of interest, and for any methods we don't decorate, we'll get the default behavior which just forwards the call to the wrapper in the base decorator: 1:     public class TimedThresholdProductDaoDecorator : ProductDaoDecorator 2:     { 3:         private static readonly ILog _log = LogManager.GetLogger(typeof(TimedThresholdProductDaoDecorator)); 4:         5:         public TimedThresholdProductDaoDecorator(IProductDao wrappedDao) : 6:             base(wrappedDao) 7:         { 8:         } 9:         10:         ... 11:         12:         public IEnumerable<Product> GetAvailableProducts() 13:         { 14:             var timer = Stopwatch.StartNew(); 15:             16:             var results = _wrapped.GetAvailableProducts(); 17:             18:             timer.Stop(); 19:             20:             if (timer.ElapsedMilliseconds > 5000) 21:             { 22:                 _log.WarnFormat("Long query in GetAvailableProducts() took {0} ms", 23:                     timer.ElapsedMillseconds); 24:             } 25:             26:             return results; 27:         } 28:     } Well, it's a bit better.  Now the logging is in its own class, and the database logic is in its own class.  But we've essentially multiplied the number of classes.  We now have 3 classes and one interface!  Now if you want to do that same logging decorating on all your DAOs, imagine the code bloat!  Sure, you can simplify and avoid creating the base decorator, or chuck it all and just inherit directly.  But regardless all of these have the problem of tying the logging logic into the code itself. Enter the Interceptors.  Things like this to me are a perfect example of when it's good to write an Interceptor using your class library of choice.  Sure, you could design your own perfectly generic decorator with delegates and all that, but personally I'm a big fan of Castle's Dynamic Proxy (here) which is actually used by many projects including Moq. What DynamicProxy allows you to do is intercept calls into any object by wrapping it with a proxy on the fly that intercepts the method and allows you to add functionality.  Essentially, the code would now look like this using DynamicProxy: 1: // Note: I like hiding DynamicProxy behind the scenes so users 2: // don't have to explicitly add reference to Castle's libraries. 3: public static class TimeThresholdInterceptor 4: { 5: // Our logging handle 6: private static readonly ILog _log = LogManager.GetLogger(typeof(TimeThresholdInterceptor)); 7:  8: // Handle to Castle's proxy generator 9: private static readonly ProxyGenerator _generator = new ProxyGenerator(); 10:  11: // generic form for those who prefer it 12: public static object Create<TInterface>(object target, TimeSpan threshold) 13: { 14: return Create(typeof(TInterface), target, threshold); 15: } 16:  17: // Form that uses type instead 18: public static object Create(Type interfaceType, object target, TimeSpan threshold) 19: { 20: return _generator.CreateInterfaceProxyWithTarget(interfaceType, target, 21: new TimedThreshold(threshold, level)); 22: } 23:  24: // The interceptor that is created to intercept the interface calls. 25: // Hidden as a private inner class so not exposing Castle libraries. 26: private class TimedThreshold : IInterceptor 27: { 28: // The threshold as a positive timespan that triggers a log message. 29: private readonly TimeSpan _threshold; 30:  31: // interceptor constructor 32: public TimedThreshold(TimeSpan threshold) 33: { 34: _threshold = threshold; 35: } 36:  37: // Intercept functor for each method invokation 38: public void Intercept(IInvocation invocation) 39: { 40: // time the method invocation 41: var timer = Stopwatch.StartNew(); 42:  43: // the Castle magic that tells the method to go ahead 44: invocation.Proceed(); 45:  46: timer.Stop(); 47:  48: // check if threshold is exceeded 49: if (timer.Elapsed > _threshold) 50: { 51: _log.WarnFormat("Long execution in {0} took {1} ms", 52: invocation.Method.Name, 53: timer.ElapsedMillseconds); 54: } 55: } 56: } 57: } Yes, it's a bit longer, but notice that: This class ONLY deals with logging long method calls, no DAO interface leftovers. This class can be used to time ANY class that has an interface or virtual methods. Personally, I like to wrap and hide the usage of DynamicProxy and IInterceptor so that anyone who uses this class doesn't need to know to add a Castle library reference.  As far as they are concerned, they're using my interceptor.  If I change to a new library if a better one comes along, they're insulated. Now, all we have to do to use this is to tell it to wrap our ProductDao and it does the rest: 1: // wraps a new ProductDao with a timing interceptor with a threshold of 5 seconds 2: IProductDao dao = TimeThresholdInterceptor.Create<IProductDao>(new ProductDao(), 5000); Automatic decoration of all methods!  You can even refine the proxy so that it only intercepts certain methods. This is ideal for so many things.  These are just some of the interceptors we've dreamed up and use: Log parameters and returns of methods to XML for auditing. Block invocations to methods and return default value (stubbing). Throw exception if certain methods are called (good for blocking access to deprecated methods). Log entrance and exit of a method and the duration. Log a message if a method takes more than a given time threshold to execute. Whether you use DynamicProxy or some other technology, I hope you see the benefits this adds.  Does it completely eliminate all need for the Decorator pattern?  No, there may still be cases where you want to decorate a particular class with functionality that doesn't apply to the world at large. But for all those cases where you are using Decorator to add functionality that's truly generic.  I strongly suggest you give this a try!

• Keyboard Simulation not working with Keyboard hook for modifier keys

  - by Eduardo Wada

  I have a piece of software that is being used to simulate a certain device on a touchscreen, this device already runs an application that receives keyboard input from the device. My software (reffered to as simulator) displays a virtual keyboard and runs the application. Thus, the simulator sends keys with input simulator: http://inputsimulator.codeplex.com/ And the applciation listens to keys with the following keyboard hook: https://svn.cyberduck.io/tags/release-4-1/source/ch/cyberduck/core/GlobalKeyboardHook.cs My problem is, what some keys from the device's hardware actually do is to sent a key combination (ex: left-alt + 1) to the application and a weird scenario is occurring: The application listens to normal keyboard inputs The simulator sends keys to other applications (ie: visual studio responds to the keys sent when debugging) The simulator can send single keys to the application (I can type) The simulator CANNOT send key combinations to the application (alt+1 is received as just 1 in the application) This started happenning when we imported the application's dll into the same process from the simulator. Could there be any reason why I can't simulate key combinations for a hook in the same process? Is there any easy fix for this?

• Registry in .NET: DeleteSubKeyTree says the subkey does not exists, but hey, it does!

  - by CharlesB

  Hi, Trying to delete a subkey tree: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.hdr. .hdr subkey has one subkey, no values. So I use this code: RegistryKey FileExts = Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts"); RegistryKey faulty = FileExts.OpenSubKey(".hdr"); Debug.Assert (faulty != null && faulty.SubKeyCount != 0); faulty.Close(); FileExts.DeleteSubKeyTree(".hdr"); And I get the ArgumentException with message "Cannot delete a subkey tree because the subkey does not exist." WTF? I checked and asserted it did exist?

• How to get httrack to work with SSL on mac os x? (libssl.so not found)

  - by cwd

  I'm trying to use httrack website copier but the program is running and reporting "no-ssl" (ie: it does not have the capability to copy secure sites). From looking over this thread, it seems that the problem is either when I make & configure the program, or when I run the program, it is not finding the lib-ssl / open-ssl that I have installed. I think it is looking for /var/root/lib/libssl.so.1.0 The user on that forum states that he created a symlink which allowed httrack to find the ssl library in the non-default location. Perhaps that's what I need to do - but where do I create the link from and to? I'm not seeing that I have any libssl.so files installed on my system. Do I need the development package? If so, how do I install that? I used macports to install the current version of openssl that I have. I'm running OS X 10.6. Reserch I have run this command to try and debug: dtruss httrack 2&1 | grep ssl and that outputs this: stat64("libssl.so.1.0\0", 0x7FFF5FBFEE30, 0x7FFF5FBFF470) = -1 Err#2

• Integrate flex 3.5 projects in flash builder 4 beta 2

  - by Cyrill Zadra

  Hi I'm currently using Flex Builder 3 and Flex SDK 3.5 for my projects. But I'd like to try out the new Flash Builder 4. So I downloaded and installed the new software, configured all the additional software like subversion, server adapter .. and finally a importet my 2 projects. 1) Main Project (includes a swc generated by the Library Project) (flex sdk 3.5) 2) Library Project (flex sdk 3.4) After the import and project cleanup the project is running perfectly. But as soon as I replace the existing LibraryProject.swc through a new one (compiled with flash builder 4 beta 2 sdk 3.4) VerifyError: Error #1014: class mx.containers::Canvas not found. VerifyError: Error #1014: class mx.containers::HBox not found. VerifyError: Error #1014: class IWatcherSetupUtil not found. ... and several others not found errors. Does anyone has the same error. How can I get my project running again? thanks & regards cyrill

• Disable debug output in libxml2 and xmlsec

  - by ereOn

  Hi, In my software, I use libxml2 and xmlsec to manipulate (obviously) XML data structures. I mainly use XSD schema validation and so far, it works well. When the data structure input by the client doesn't match the XSD schema, libxml2 (or xmlsec) output some debug strings to the console. Here is an example: Entity: line 1: parser error : Start tag expected, '<' not found DUMMY<?xml ^ While those strings are useful for debugging purposes, I don't want them to appear and polute the console output in the released software. So far, I couldn't find an official way of doing this. Do you know how to suppress the debug output or (even better) to redirect it to a custom function ? Many thanks.

• How to get users to read error messages?

  - by FX

  If you program for a nontechnical audience, you find yourself at a high risk that users will not read your carefully worded and enlightening error messages, but just click on the first button available with a shrug of frustration. So, I'm wondering what good practices you can recommend to help users actually read your error message, instead of simply waiving it aside. Ideas I can think of would fall along the lines of: Formatting of course help; maybe a simple, short message, with a "learn more" button that leads to the longer, more detailed error message Have all error messages link to some section of the user guide (somewhat difficult to achieve) Just don't issue error messages, simply refuse to perform the task (a somewhat "Apple" way of handling user input) Edit: the audience I have in mind is a rather broad user base that doesn't use the software too often and is not captive (i.e., not an in-house software or narrow community). A more generic form of this question was asked on slashdot, so you may want to check there for some of the answers.

• Check firebird databases present

  - by Ronaldo Junior

  Our software installer install firebird if it is not present on the system and, as we are pursuing Win certificate the uninstaller should remove it but, we want to make sure that even if it was the installer that put it there, if any new software is using it now with a new database, we would not remove it (Firebird). The question is: Is it possible to query the server and ask what are the databases running on it? This is it so that we can decide, automatically if we can remove the database or not. A few extra info: Our installer is Innosetup and it does a good job already - we just trying to make it smarter because of the "Developed by" or "Compatible with" windows logo.

• Testing harness for online teaching?

  - by candeira

  I have been asked to teach an online programming course, and I am looking for a test harness especially geared to education. Some students will have significant coding experience, but others will be total newbies. The course is an introduction to software development, mostly taught in C with some C++ and Java thrown in. In any case, I would like to read their source code only after a test suite has made sure that it compiles and executes properly. The students will also benefit from having a tool they can check their code against before submitting it. However, the Learning Management System my employer is using doesn't have such a system. Do you know of any LMS software that includes this feature? Which testing harness would you recommend in case I have to roll my own?

• How can I reprogram a USB "easy button"?

  - by Shawn Simon

  I have a USB "easy button"- is a USB cable attached to a large button. It appears as a keyboard to the computer. When I push the button, it sends the keys Start+R and then quickly types in a pre-configured URL. I am fairly certain that the company that produces these buttons sets the URL via some sort of software over USB. How could I reprogram the button myself? What sort of software would I need? Here is a link to the website: http://www.usbsmartbuttons.com/

• Do you know any alternative to NDepend for architects?

  - by ifesdjeen

  Hi! do you know any software similar to NDepend? I've got it just recently, and found it very useful. It helped me a lot, but for now i don't have a possibility to buy a proffessional version. So, is there any alternative (maybe, open-source)? Preferrably, free. But not necessarily. Maybe, with a little bit more fitting price for a single-developer, not a team. Requirements for this software: Build dependency diagrams Retrieve code metrics Display comments coverage (so far)

• Are there any famous one-man-army programmers?

  - by DFectuoso

  Lately I have been learning of more and more programmers who think that if they were working alone, they would be faster and would deliver more quality. Usually that feeling is attached to a feeling that they do the best programming in their team and at the end of the day the idea is quite plausible. If they ARE doing the best programming, and worked alone (and more maybe) the final result would be a better piece of software. I know this idea would only work if you where enough passionate to work 24/7, on a deadline, and great discipline. So after considering the idea and trying to learn a little more, I wonder if there are famous one-man-army programmers that have delivered any (useful) software in the past?

• WAN Optimization Resources

  - by Paul

  I'm looking for resources on writing software to do WAN optimization. I've googled this and searched SO, but there doesn't seem to be much around. The only things I've found are high-level articles in tech magazines, and info for network admins on how to make use of existing WAN optimization products. I'm looking for something on the techniques etc. used to write WAN optimization software. It seems to be a dark art, and the people who know how to do it, guard their secrets closely. Any suggestions?

• Stress Test tool for Password Protected Website

  - by Jason

  We need to run a stress test on a password protection section of a website we host. What tool (paid or free) would be best for us to use for this? We'd like to be able to create several 'scripts' and then have the stress test simulate X number of users. Each script will have us login as a specific user and then click on some links and submit forms to simulate an actual user. Ideally the software would also create some nice data exports/charts. Server is a linux web server, but we could run this on linux or Windows so software that will run on either is fine.

• Handling User Authentication in C#.NET?

  - by Daniel

  I am new to .NET, and don't have much experience in programming. What is the standard way of handling user authentication in .NET in the following situation? 1.In Process A, User inputs ID/Password 2.Process A sends the ID/Password to Process B over a nonsecure public channel. 3.Process B authenticates the user with the recieved ID/Password what are some of the standard cryptographic algorithms I can use in above model? The users(customers that bought my company's software) will be running the software(Process A) locally in their computer(connected to internet). I need to authenticate the users so that only registered users can run the program. Thank You!
