• Strange WndProc bug in .Net. VB.Net more specifically.

  - by Jules

  ETA: I use visual studio 2008 express edition. If I override WndProc and mess up somehow, I'll usually backtrack by commenting out code until it works again. The strange thing with WndProc though is you can strip it down to: Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) MyBase.WndProc((m)) End Sub and it still throws the error. I have to remove the code and retype it in to reset the error. Anyone else experienced this?

• use doctest and logging in python program

  - by Luke

  #!/usr/bin/python2.4 import logging import sys import doctest def foo(x): """ foo (0) 0 """ print ("%d" %(x)) _logger.debug("%d" %(x)) def _test(): doctest.testmod() _logger = logging.getLogger() _logger.setLevel(logging.DEBUG) _formatter = logging.Formatter('%(message)s') _handler = logging.StreamHandler(sys.stdout) _handler.setFormatter(_formatter) _logger.addHandler(_handler) _test() I would like to use logger module for all of my print statements. I have looked at the first 50 top google links for this, and they seem to agree that doctest uses it's own copy of the stdout. If print is used it works if logger is used it logs to the root console. Can someone please demonstrate a working example with a code snippet that will allow me to combine. Note running nose to test doctest will just append the log output at the end of the test, (assuming you set the switches) it does not treat them as a print statement.

• Permanently Delete MailMessage in Outlook with VBA?

  - by eidylon

  Hello all, I am looking for a way to permanently delete a MailMessage from Outlook 2000 with VBA code. I'd like to do this without having to do a second loop to empty the Deleted items. Essentially, I am looking for a code equivalent to the UI method of clicking a message and hitting SHIFT+DELETE. Is there such a thing? TIA!

• WCF XmlSerializer assembly not speeding up first request

  - by Matt Dearing

  I am generating proxy classes to a clients java webservice wsdls and xsd files with svcutil. The first call made to each service proxy class takes a very long time. I was hoping to speed this up by generating the XmlSerializers assembly myself (based on the article How to: Improve the Startup Time of WCF Client Applications using the XmlSerializer), but when I do the first call to each service still takes the same amount of time. Here are the steps I am following: //generate strong name key file sn -k Blah.snk //generate the proxy class file svcutil blah.wsdl blah2.wsdl blah3.wsdl ... base.xsd blah.xsd ... /UseSerializerForFaults /ser:XmlSerializer /n:*,SomeNamespace /out:Blah.cs //compile the class into an assembly signing it with the strong name key file csc /target:library /keyfile:Blah.snk /out:Blah.dll Blah.cs //generate the XmlSerializer code this will give us Blah.XmlSerializers.dll.cs svcutil /t:xmlSerializer Blah.dll //compile the xmlserializer code into its own dll using the same key to sign it and referencing the original dll csc /target:library /keyfile:Blah.snk /out:Blah.XmlSerializers.dll Blah.XmlSerializers.dll.cs /r:Blah.dll I then create a standard Console application that references both Blah.dll and Blah.XmlSerializers.dll. I will then try something like: //BlahProxy is one of the generated service proxy classes BlahProxy p = new BlahProxy(); //this call takes 30ish seconds p.SomeMethod(); BlahProxy p2 = new BlahProxy(); //this call takes < 1 second p2.SomeMethod(); //BlahProx2y is one of the generated service proxy classes BlahProxy2 p3 = new BlahProxy2(); //this call takes 30ish seconds p3.SomeMethod(); BlahProxy2 p4 = new BlahProxy2(); //this call takes < 1 second p4.SomeMethod(); I know that the problem is not server side because I don't see the request made in Fiddler until around 29 seconds. Subsequent calls to each service take < 1 second, so thats why I was hoping the main slow down was the .net runtime generating the xmlserializer code itself, compiling it and loading the assembly. I figured this would be the reason the first call to each service is slow and the rest are fast. Unfortunatley, me generating the code myself is not speeding anything up. Does anyone see what I am doing wrong?

• Multiple Headers in asp.net

  - by digiguru

  I'm running code that seems to hit the "AppendHeader" twice in the code. Response.Filter = New DeflateStream(Response.Filter, CompressionMode.Compress, True) Response.AppendHeader("Content-encoding", "deflate") ... Response.AppendHeader("Content-encoding", "deflate") I have tried using the following.... Response.Headers("Content-encoding") = "deflate" But it says This operation requires IIS integrated pipeline mode. How do I check for a headers existence, and overwrite it rather than appending it.

• OpenSSL: how to setup an OCSP server for checking third-party certificates?

  - by StackedCrooked

  I am testing the Certificate Revocation functionality of a CMTS device. This requires me to setup a OCSP responder. Since it will only be used for testing I assume that the minimal implementation provided by OpenSSL should suffice. I have extracted the a certificate from a cable modem, copied it to my PC and converted it to the PEM format. Now I want to register it in the OpenSSL OCSP database and start a server. I have completed all these steps, but when I do a client request my server invariably responds with "unknown". It seems to be completely unaware of my certificate's existence. I would greatly appreciate if anyone would be willing to have a look at my code. For your convenience, I have created a single script consisting of a sequential list of all used commands, from setting up the CA until starting the server: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/AllCommands.sh You can also find the custom config file and the certificate that I am testing with: http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/ Any help would be greatly appreciated.

• List all possible combinations of k integers between 1...n (n choose k)

  - by Asaf R

  Hi, Out of no particular reason I decided to look for an algorithm that produces all possible choices of k integers between 1...n, where the order amongst the k integer doesn't matter (the n choose k thingy). From the exact same reason, which is no reason at all, I also implemented it in C#. My question is: Do you see any mistake in my algorithm or code? And, more importantly, can you suggest a better algorithm? Please pay more attention to the algorithm than the code itself. It's not the prettiest code I've ever written, although do tell if you see an error. EDIT: Alogirthm explained - We hold k indices. This creates k nested for loops, where loop i's index is indices[i]. It simulates k for loops where indices[i+1] belongs to a loop nested within the loop of indices[i]. indices[i] runs from indices[i - 1] + 1 to n - k + i + 1. CODE: public class AllPossibleCombination { int n, k; int[] indices; List<int[]> combinations = null; public AllPossibleCombination(int n_, int k_) { if (n_ <= 0) { throw new ArgumentException("n_ must be in N+"); } if (k_ <= 0) { throw new ArgumentException("k_ must be in N+"); } if (k_ > n_) { throw new ArgumentException("k_ can be at most n_"); } n = n_; k = k_; indices = new int[k]; indices[0] = 1; } /// <summary> /// Returns all possible k combination of 0..n-1 /// </summary> /// <returns></returns> public List<int[]> GetCombinations() { if (combinations == null) { combinations = new List<int[]>(); Iterate(0); } return combinations; } private void Iterate(int ii) { // // Initialize // if (ii > 0) { indices[ii] = indices[ii - 1] + 1; } for (; indices[ii] <= (n - k + ii + 1); indices[ii]++) { if (ii < k - 1) { Iterate(ii + 1); } else { int[] combination = new int[k]; indices.CopyTo(combination, 0); combinations.Add(combination); } } } } I apologize for the long question, it might be fit for a blog post, but I do want the community's opinion here. Thanks, Asaf

  I want to build a custom control to reuse in my project which consists of two UITextFields that are linked together + a label. It is starting to become repetitive across my App and smells of code duplication ;) However, I wonder what is the best aproach here. Is it best do everything by code in a controller or is posible do a visual thing like the ones built-in in Xcode?

• SmtpClient.Send() complains of incorrect no of overloads when passing in MailMessage object

  - by dotnetdev

  Hi, I have this code written in .NET 4.0 using VS2010 Ultimate Beta 2: smtpClient.Send(mailMsg); smtpClient is a reference to SmtpClient (I have the relevant references added), and likewise for mailMsg (is MailMessage) - there are no errors stating anything like check for missing assemblies. However, I keep getting an error saying that I have the incorrect no of overloads, when SmtpClient takes either a MailMessage object or the To address, From address, Subject, etc. Why doesn't this code work? Totally confused. Thanks

• Java REPL shell

  - by Don

  Hi, I'm looking for a REPL shell that I can use to test out snippets of Java code. Either a desktop app, or a web app (like the Groovy web console). Ideally, commonly used Java packages like: java.io.* java.util.* should be automatically imported, so that I can copy and paste code from a class without having to add a bunch of imports. Does such a thing exist? Thanks, Donal

• Session Objects not Updating ASP.NET

• Turing-Complete language possibilities?

  - by I can't tell you my name.

  In every Turing-Complete language, is it possible to create a working Compiler for itself which first runs on an interpreter written in some other language and then compiles it's own source code? (Bootstrapping) Standards-Compilant C++ compiler which outputs binaries for, e.g.: Windows? Regex Parser and Evaluater? World of Warcraft clone? (Assuming the language gets the necessary API bindings as, for example, OpenGL and the WoW source code is available) (Everything here theoretical) Let's take Brainf*ck as an example language.

• Get directory contents in date modified order

  - by nevan

  Is there an method to get the contents of a folder in a particular order? I'd like an array of file attribute dictionaries (or just file names) ordered by date modified. Right now, I'm doing it this way: get an array with the file names get the attributes of each file store the file's path and modified date in a dictionary with the date as a key Next I have to output the dictionary in date order, but I wondered if there's an easier way? If not, is there a code snippet somewhere which will do this for me? Thanks.

• What are the differences between GIT and SVN when it comes to merge conflicts solving.

  - by chalup

  I keep hearing that branching in git is so much easier than in SVN, because it's easier to merge the branch back to trunk/master. I've read some tutorials, but they only covered basic merge conflicts ("Alice changed line 8 of code.cpp and at the same time Bob changed line 8 of code.cpp...") and there are no differences between SVN and all other distributed source control systems. Can you give me the examples of changes in branch that would cause troubles in SVN repository, but would be handled gracefully by git?

• Best strategy for HTML partial rendering based on multiple dropdown values

  - by pv2008

  I have a View that renders something like this: "Item 1" and "Item 2" are <tr> elements from a table. After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...". I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example. But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.
