• ASP.NET HTTPHandler not throwing exception when one is expected

  - by josephj1989

  I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is written. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"}); If I put a breakpoint on the File.WriteAllLines statement and then step over it I can see an exception occurring.

• How to convert JavaScript dictionary into Python syntax

  - by Sputnix

  Writing out javascript dictionary from inside of JavaScript- enabled application (such as Adobe) into external .jsx file (or any other .txt file) the context of resulted file dictionary looks like: ({one:"1", two:"2"}) (Please note that each dictionary keys are written as they are the variables name (which is not true). A next step is to read this .jsx file with Python. I need to find a way to convert ({one:"1", two:"2"}) into Python dictionary syntax such as: {'one':"1", 'two':"2"} It has been already suggested that instead of using JavaScript's built-in dict.toSource() it would make more sense to use JSON which would write a dictionary content in similar to Python syntax. But unfortunately using JSON is not an option for me. I need to find a way to convert ({one:"1", two:"2"}) into {'one':"1", 'two':"2"} using Python alone. Any suggestions on how to achieve it? Once again, the problem mostly in dictionary keys syntax which inside of Python look like variable names instead of strings-like dictionary keys names: one vs "one"

• property not updating in object when page is posted

  - by Jared

  Hi I have set a property in a constructor like so function __construct() { $this->count = count(@$_SESSION['filearray']); //count how many files in array } and using it in condition statements if($this->count > 10) //then do something but it appears the count isn't being updated when I use another method of injecting values into this 'filearray' until I refresh the page. am I doing something wrong? I thought that my constructor would detect a change had been made in the session and whenever I call $this-count I would get the current count value but it seems to be 1 step behind until I refresh the page. If this is all vague I can include my form page that has all the method calls, but this is the jist of my question, why is my property not updating and how do I fix it :) TIA

• VS 2008 Profiler - Caller/Callee view showing bottom of stack

  - by Ncc

  Hello, I am currently trying to profile a class contained in a different assembly. To do this I created a small console application which calls into the public entry point of the class I want to profile. This enrty point is called Run(). This is working fine when I run my Console application in Debug mode and I can step into the Run() method. The Run() method calls a variety of other methods in its own assembly and other assemblies. However, when I create a new profiler of type "Instrumentation" in VS 2008, and run the profiler, the report shows my Main() function calling Run(), but in turn, when viewing the Caller/Callee report for my Run() method the report shows that the Run() method is the bottom of the stack. This is clearly not the case - could anyone please suggest why this is happening? Thanks.

• Save/restore git/cvs checkout changes when switching branches?

  - by Dale Forester

  Using cvs, git or another technique (file system level?), I would like to: Make modifications on branch A Checkout branch B: Changes to branch A are "stowed away" (by name would be nice), branch B is checked out such that my branch A changes are gone Make modifications on branch B Checkout branch A: Changes to branch B are "stowed away" (by name would be nice), branch A is checked out such that my branch B changes are gone but now my "saved" branch A changes from Step #2 are back Git-stash does not appear to fit the flow I'm describing although my impression could be wrong. Techniques involving RCS's or file system or command-line tools or otherwise are welcome.

• ado.net slow updating large tables

  - by brett

  The problem: 100,000+ name & address records in an access table (2003). Need to iterate through the table & update detail with the output from a 3rd party dll. I currently use ado, and it works at an acceptable speed (less than 5 minutes on a network share). We will soon need to update to access 2007 and its 'non jet' accdb format to maintain compatability with clients. I've tried using ado.net datsets, but updating the records takes hours! We process 5-10 of these tables per day - so this cannot be a solution. Any ideas on the fastest way to update individual records using ado.net? Surely we didn't take such a hugh backward step with ado.net? Any help would be appreciated.

• Dynamically loading hi-res images into UIScrollView

  - by Jeff

  I've been looking into creating a gallery mode in my application. The functionality will be identical to the built in Photos App. Here's the flow: 1. You touch on a thumbnail and ... 2. a modal view displays a large detail version of the image 3. You have the ability to scroll horizontally through all the images in the gallery while in this modal view I'm stuck on step 3. How do I dynamically load hi res images into a scroll view? I understand I need to set the contentSize for the the scrollView but how do I do that when I've only selected and loaded one image? What delegate methods do I need to implement and what does the heavy lifting look like? Thanks in advance!

• Combining SpecFlow table and Moq mocked object

  - by Confused

  I have a situation where I want to use a mocked object (using Moq) so I can create setup and expectations, but also want to supply some of the property values using the SpecFlow Table. Is there a convenient way to create a mock and supply the table for the seed values? // Specflow feature Scenario Outline: MyOutline Given I have a MyObject object as | Field | Value | | Title | The Title | | Id | The Id | // Specflow step code Mock<MyObject> _myMock; [Given(@"I have a MyObject object as")] public void GivenIHaveAMyObjectObjectAs(Table table) { var obj = table.CreateInstance<MyObject>(); _myMock = new Mock<MyObject>(); // How do I easily combine the two? }

  - by Verrtex

  Hi All, I am trying to install MySQLdb package. I found the source code here. I did the following: gunzip MySQL-python-1.2.3c1.tar.gz tar xvf MySQL-python-1.2.3c1.tar cd MySQL-python-1.2.3c1 python setup.py build As the result I got the following: Traceback (most recent call last): File "setup.py", line 5, in ? from setuptools import setup, Extension ImportError: No module named setuptools Does anybody knows how to solve this problem? By the way, if I am able to do the described step, I will need to do the following: sudo python setup.py install And I have no system-administrator-rights. Do I still have a chance to install MySQLdb? Thank you.

• Newbie Question: Read and Process a List of Text Files

  - by johnv

  I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET): Dim tRead As System.IO.StreamReader Public Function ReadFile() As String Dim EntireFile As String tRead = File.OpenText("c:\textexample\00001.txt") EntireFile = tRead.ReadToEnd Return EntireFile End Function Public Function Step1() ..... End Function Public Function Step2() ..... End Function .............. I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file. Any help is greatly appreciated. ReplyQuote

• Push origin master error on new repository.

  - by thaiyoshi

  I just started using git with github. I followed their instructions and ran into errors on the last step. I'm checking in an existing directory that isn't currently source-controlled (project about a week old). Other than that, my use case should be pretty run of the mill. Here's what's happening: $ git push origin master error: src refspec master does not match any. fatal: The remote end hung up unexpectedly error: failed to push some refs to '[email protected]:{username}/{projectname}.git' Github's instructions: Global setup: Download and install Git git config --global user.name "Your Name" git config --global user.email {username}@gmail.com Next steps: mkdir projectname cd projectname git init touch README git add README git commit -m 'first commit' git remote add origin [email protected]:{username}/{projectname}.git git push origin master

• How can I put double quotes inside a string within an ajax JSON response?

  - by karlthorwald

  I receive a JSON response in an Ajax request from the server. This way it works: { "a" = "1", "b" = "hello 'kitty'" } But I did not succeed in putting double quotes around kitty. When I convert " to \x22 in the Ajax response, it is still interpreted as " by JavaScript and I cannot parse the JSON. Should I also escape the \ and unescape later (which would be possible)? How to do this? Edit: I am not sure if i expressed it well: I want this string inside of "b" after the parse: hello "kitty" If necessary I could also add an additional step after the parse to convert "b", but I guess it is not necessary, there is a more elegant way so this happens automatically?

• Removing entity bug

  - by Greg

  hello, I am trying out the ria services and I am experiencing this problem that seems very strange to me. I am creating a new entity of type "House" and add it to context without saving the context so the id of the new entity is 0, after i remove this entity and add another new entity of type "House" again and again without saving the context, here comes the weird part, now I have an entity of type "City" which holds entityset of all "Houses" in that city, so to put the newly created entity "House" into the city i do something like this - house.City = city, where house is type "House" and city is type "City", afte this step a check the context and suddenly there are 2 entities of type "House" with id 0, one of them is the one I have deleted at the beginning. Any idea what is causing this and how to fix it?? thank you Greg

• How to schedule daily backup in MSSQL Server 2008 Web Edition

• Core dump utility for .NET

  - by Dave

  In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

• Order hybrid mixed mysql search result in one query?

  - by Fredrik

  This problem is easy fixed clientside. But for performance I want to do it directly to the database. LIST a +------+-------+-------+ | name | score | cre | +------+-------+-------+ | Abe | 3 | 1 | | Zoe | 5 | 2 | | Mye | 1 | 3 | | Joe | 3 | 4 | Want to retrieve a joined hybrid result without duplications. Zoe (1st higest score) Joe (1st last submitted) Abe (2nd highest score) Mye (2nd last submitted) ... Clientside i take each search by itself and step though them. but on 100.000+ its getting awkward. To be able to use the LIMIT function would ease things up a lot! SELECT name FROM a ORDER BY score DESC, cre DESC; SELECT name FROM a ORDER BY cre DESC, score DESC;

• What's the best way to handle web.config file versions in ASP.Net?

  - by MusiGenesis

  I have an ASP.Net web site (ASPX and ASMX pages) with a single web.config file. We have a development version and a production version. Over time, the web.config files for development and production have diverged substantially. What is the best practice for keeping both versions of web.config in source control (we use Tortoise SVN but I don't think that matters)? It seems like I could add the production web.config file with a name like "web.config.prod", and then when we turnover all the files we would just add the step of deleting the existing web.config and renaming web.config.prod to web.config. This seems hackish, although I'm sure it would work. Is there not some mechanism for dealing with this built in to Visual Studio? It seems like this would be a common issue, but I haven't found any questions (with answers) about this.

• CRM plugin to execute when opportunity is reopened

  - by splatto

  I need to write a plugin for Dynamics CRM 4.0 that executes when a closed opportunity is reopened in order to change the salesstagecode. My questions are: When I register a new step to the plugin, what attribute(s) should I filter on? What property on the entity should I check the value of? and What should I look for the value of this entity to be so I can determine if the plugin execution should continue? I've typically written asynchronous workflows and my experience writing plugins is still developing, so I'd appreciate any help and clarification that can be offered. Please see below the plugin skeleton I've written public void Execute(IPluginExecutionContext context) { if (context.InputParameters.Properties.Contains("Target") && context.InputParameters.Properties["Target"] is DynamicEntity) { ICrmService service = context.CreateCrmService(false); DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties["Target"]; if (entity.Name == EntityName.opportunity.ToString()) { if (entity.Properties.Contains(/*What Property Should I Check Here?*/)) { //And what value should I be looking for in that property? } } } }

• MOSS Collect Data from user custom email

  - by nav

  Hi, I am trying to send out a custom email, after the Collect Data from user step in my primary workflow which starts when an item in list X is created. I have created a secondary workflow to start when a new Task item is created (this is created by the Collect Data from user action in the primary workflow). But I am having problem how I retrieve the information on the list X. I know the ID of the referenced item in List X is stored in a URL within the "Link" column in the Tasks lists. But can't see any string manipulation function that will grab this ID so I can use it to link back to relevant item in List X. Is there an easier way to do this? Many Thanks, Nav

• "Attach to process" missing from Delphi 7's Run menu

  - by glob

  I have to resurrect an ancient Delphi 7 application, which means I have to use the D7 IDE. Upgrading the project to a more recent version of Delphi unfortunately isn't an option. My new D7 installation's Run menu is missing Attach to Process. Aside from the missing menu item, the debugger works fine (I can debug normal Delphi executables started with Run). I know D7 supported this feature (it's in the help file), so does anyone have any idea what I've missed? The installation is Delphi 7 Enterprise (Version 7.0 Build 4.453). Current Run menuitems: Run Parameters... - Step Over Trace Into Trace to next Source line Run to Cursor Run Until Return Show Execution Point Program Pause Program Reset - Evaluate/Modify Add Watch Add Breakpoint

• Visual Studio debugger problem

  - by Alexandre Pepin

  In Visual Studio 2008, after debugging about 1-2 minutes, when I press F10 (Step Over), the debugger hangs and Visual Studio freezes for 5-10 seconds and then go to the next line. Then whatever I do (F10, F5, F11, etc), the debugger continues the execution as if i pressed F5 and all my forms that I was debugging close. I always have to restart the application. It is very hard to reproduce and it does not occurs every time I want to debug something. Does anyone has a solution ?

• How to import a macro file (previously exported as .bas file) to Microsoft Word using command line?

  - by Nam Gi VU

  I'm writing a command-line program that has a step in which I need to replace text in a Word file. The replacing task is accomplished using Word macro. What I need to do now is to call this macro from command-line. At the moment we can do this by using the -mMacroName parameter of 'winword.exe', i.e. \winword.exe -mMacroName. But this need the macro to be already available as a global macro. Since I need to run the program on another computer, I need to import the above replacing macro programatically... and I don't know how to do this. Please help.

• Best way to use SFTP folder as concurrent work queue

  - by Gabe Moothart

  I am writing a c# windows service which will be polling an SFTP folder for new files (one file = one job) and processing them. Multiple instances of the service may be running at the same time, so it is important that they do not step on each other. I realize that an SFTP folder does not make an ideal queue, but that's what I have to work with. What do I need to do to either use this SFTP folder as a concurrent message queue, or safely represent it in a way that can be used concurrently?
