• How do I convert a windows forms app from C# to VB ?

  - by SLC

  I've been converting all kinds of other things, classes, interfaces, ASP.NET MVC apps, and WPF applications, but I am stumped as to how to convert a windows forms application, as the whole structure seems to be different. Does anyone have any advice on how to tackle this problem? I see essentially that you have two files, Form1.cs and Form1.Designer.cs. Literally translating them from C# to VB doesn't work because of some intricacies or other of how Visual Basic works. I think you /might/ be able to convert Form1.cs in this way, as it's just a constructor plus event handlers, but the designer contains the references to the controls etc. and I am not sure how to go about doing that. I am using Visual Studio 2010 Beta 2.

• How Do I Pull Info from String

  - by Russ Bradberry

  I am trying to pull dynamics from a load that I run using bash. I have gotten to a point where I get the string I want, now from this I want to pull certain information that can vary. The string that gets returned is as follows: Records: 2910 Deleted: 0 Skipped: 0 Warnings: 0 Each of the number can and will vary in length, but the overall structure will remain the same. What I want to do is be able to get these numbers and load them into some bash variables ie: RECORDS=?? DELETED=?? SKIPPED=?? WARNING=?? In regex I would do it like this: Records: (\d*?) Deleted: (\d*?) Skipped (\d*?) Warnings (\d*?) and use the 4 groups in my variables.

• How to add sort function for the table via ajax in ASP.NET MVC?What is the best practice.

  - by Eric Wang

  How to add sort function for the table via ajax in ASP.NET MVC?What is the best practice. If not use Ajax, it maybe much easier, just return View, but if use AJAX, what data structure should return?I just use Json to return the data, but i found each JSON data model return to the client browser, the JS have to use different code to parse it, remove the originally table rows, add the new data rows(because the column is different) etc. It make me crazy, is there any better way to do that? Thank you for any advice.

• How do you handle large repeated UI elements with JQuery

  - by jpoz

  Howdy, Here's the situation: You have a very complex UI element that is repeated in a list. Each has a menu on it, buttons, it hides and shows subelements, buttons for switch it's state, etc, etc. The elements are populated via JSON so you have to construct the elements and the functionality of the fly. What's the best way to accomplish this with JQuery? Where would you save the reusable template for the DOM structure? How would you add the behavior on? $().live? .livequery? onclick? manual after every JSON get? I guess I just see a lot of people doing different things. What's your experience with performance? Any insight would be much appreciated. Thanks, JPoz

• Get entire text of document as a string using javascript

  - by Tom Dignan

  I am developing a firefox extension and ideally would be able to get the whole darn DOM as a string.. forget any data structure. I just want what I see in "view source" in a buffer. I have been checking out javascript references and HTMLDocument etc. with no avail. Ideally I would be able to write to this buffer as well (seems possible i.e. document.writeLn()) I wish there was a document.read()? Am I just a js noob?

• Web design process with CSS - during or after?

  - by SyaZ

  Which is the better practice? Add CSS during web designing you can see the result (or close) as early as possible and make required changes. You also know how many divs or spans you might need (eg to make curved cross-browser hover background). But as you add more and more components to the page sometimes things get hack-ish as you need to patch here and there to get the exact design required. Add CSS after finishing page design you can see the page overall structure as it is well, without styles. You get to see how accessible your site is, and modify it right away if it's not good enough (unlike the former case where you may break multiple CSS rules). Plus after you finished it, you only need to spend most of the time to alter only the CSS file, which is good to get the momentum going. Granted I have never tried the latter approach, but am seriously considering it for my next project if I can see convincing reasons -- or if it's no good at all. Thanks.

• Haskell Ord instance with a Set

  - by mvid

  I have some code that I would like to use to append an edge to a Node data structure: import Data.Set (Set) import qualified Data.Set as Set data Node = Vertex String (Set Node) deriving Show addEdge :: Node -> Node -> Node addEdge (Vertex name neighbors) destination | Set.null neighbors = Vertex name (Set.singleton destination) | otherwise = Vertex name (Set.insert destination neighbors) However when I try to compile I get this error: No instance for (Ord Node) arising from a use of `Set.insert' As far as I can tell, Set.insert expects nothing but a value and a set to insert it into. What is this Ord?

• python: list modules within the package

  - by ak

  I have a package with a few modules, each module has a class (or a few classes) defined within it. I need to get the list of all modules within the package. Is there an API for this in python?

• How to implement arrays in an interpreter?

  - by Ray

  I have managed to write several interpreters including Tokenizing Parsing, including more complicated expressions such as ((x+y)*z)/2 Building bytecode from syntax trees Actual bytecode execution What I didn't manage: Implementation of dictionaries/lists/arrays. I always got stuck with getting multiple values into one variable. My value structure (used for all values passed around, including variables) looks like this, for example: class Value { public: ValueType type; int integerValue; string stringValue; } Works fine with integers and strings, but how could I implement arrays? (From now on with array I mean arrays in my experimental language, not in C++) How can I fit the array concept into the Value class above? Is it possible? How should I make arrays able to be passed around just as you could pass around integers and strings in my language, using the class above? Accessing array elements or memory allocation wouldn't be the problem, I just don't know how to store them.

• How to compile these 2 java files correctly?

  - by user198729

  I'm following the steps here, it's basically : Compile the DataSource and LiveStream classes: javac -d . DataSource.java LiveStream.java Run using JMStudio: java JMStudio screen://0,0,160,120/10 But when I compile them, got lots of errors like javax.media doesn't exist and so on. Here's the directory structure: D:\>dir 2010-06-11 22:25 <DIR> . 2010-06-11 22:25 <DIR> .. 2010-06-11 22:25 3,730 DataSource.java 2010-06-11 22:25 6,860 LiveStream.java Can someone give more detailed steps how to set up the environment correctly to compile correctly?

• Is there a way to add an elmah rss feed to google reader?

  - by Jason Irwin

  Elmah has an rss feed and rss digest feature. My feeds are working just fine from within my brwoser. However I would like to add them to google reader as this is my feed reader of choice. The problem is that Elmah uses an AXD handler to server its information - therefore the path to the RSS feed is not a physical one. For example the RSS feed for my site is located at: http://www.mysite.com/errors/elmah.axd/rss This is not a file nor does the folder structure exist - it is all part of the beauty of Elmah. When I attempt to add this virtual path as a feed in google reader i get: Your search did not match any feeds Any help would be greatly appreciated, Thanks Jason

• Track each request to the website

  - by stacker

  I want to save each request to the website. In general I want to include the following information: User IP, The web site url. Response time, response success-failed status. Is it reasonable to collect the 1 and 2 in the same action? (like same HttpModule)? Do you know about any existing structure that I can follow that track every request/response-status to the website? The data need to be logged to sql server.

• Single Large v/s Multiple Small MySQL tables for storing Options

  - by Prasad

  Hi there, I'm aware of several question on this forum relating to this. But I'm not talking about splitting tables for the same entity (like user for example) Suppose I have a huge options table that stores list options like Gender, Marital Status, and many more domain specific groups with same structure. I plan to capture in a OPTIONS table. Another simple option is to have the field set as ENUM, but there are disadvantages of that as well. http://www.brandonsavage.net/why-you-should-replace-enum-with-something-else/ OPTIONS Table: option_id <will be referred instead of the name> name value group Query: select .. from options where group = '15' - Since this table is expected to be multi-tenant, the no of rows could grow drastically. - I believe splitting the tables instead of finding by the group would be easier to write & faster to execute. - or perhaps partitioning by the group or tenant? Pl suggest. Thanks

• How to merge data from two separate access 2007 databases

  - by DiegoMaK

  Hi, I have two identical databases with same structure, database a in computer a and database b in computer b. The data of database a*(a.accdb)* and database b*(b.accdb)* are different. then in database a i have for example ID:1, 2, 3 and in database B i Have ID:4,5,6 Then i need merge these databases data in only one database(a or b, doesn't matter) so the final database looks like. ID:1,2,3,4,5,6 I search an easy way to do this. because i have many tables. and do this by union query is so tedious. I search for example for a backup option for only data without scheme as in postgreSQl or many others RDBMS, but i don't see this options in access 2007. pd:only just table could be have duplicate values(I guess that pk doesn't allow copy a duplicate value and all others values will be copied well). if i wrong please correct me. thanks for your help.

• How to index a string like "aaa.bbb.ddd-fff" in Lucene?

  - by user46703

  Hi, I have to index a lot documents that contain reference numbers like "aaa.bbb.ddd-fff". The structure can change but it's always some arbitrary numbers or characters combined with "/","-","_" or some other delimiter. The users want to be able to search for any of the substrings like "aaa" or "ddd" and also for combinations like "aaa.bbb" or "ddd-fff". The best I have been able to come up with is to create my own token filter modeled after the synonym filter in "Lucene in action" which spits out multiple terms for each input. In my case I return "aaa.bbb", "bbb.ddd","bbb.ddd-fff" and all other combinations of the substrings. This works pretty well but when I index large documents (100MB) that contain lots of such strings I tend to get out of memory exceptions because my filter returns multiple terms for each input string. Is there a better way to index these strings?

• Fast read of certain bytes of multiple files in C/C++

  - by Alejandro Cámara

  I've been searching in the web about this question and although there are many similar questions about read/write in C/C++, I haven't found about this specific task. I want to be able to read from multiple files (256x256 files) only sizeof(double) bytes located in a certain position of each file. Right now my solution is, for each file: Open the file (read, binary mode): fstream fTest("current_file", ios_base::out | ios_base::binary); Seek the position I want to read: fTest.seekg(position*sizeof(test_value), ios_base::beg); Read the bytes: fTest.read((char *) &(output[i][j]), sizeof(test_value)); And close the file: fTest.close(); This takes about 350 ms to run inside a for{ for {} } structure with 256x256 iterations (one for each file). Q: Do you think there is a better way to implement this operation? How would you do it?

• Order database results by bayesian rating

  - by One Trick Pony

  I'm not sure this is even possible, but I need a confirmation before doing it the "ugly" way :) So, the "results" are posts inside a database which are stored like this: the posts table, which contains all the important stuff, like the ID, the title, the content the post meta table, which contains additional post data, like the rating (this_rating) and the number of votes (this_num_votes). This data is stored in pairs, the table has 3 columns: post ID / key / value. It's basically the WordPress table structure. What I want is to pull out the highest rated posts, sorted based on this formula: br = ( (avg_num_votes * avg_rating) + (this_num_votes * this_rating) ) / (avg_num_votes + this_num_votes) which I stole form here. avg_num_votes and avg_rating are known variables (they get updated on each vote), so they don't need to be calculated. Can this be done with a mysql query? Or do I need to get all the posts and do the sorting with PHP?

• Wordpress Taxonomy

  - by ninusik

  I am creating a Wordpress blog (no live link yet because it's still at a planning stage). I want to set up the following tag structure: Category 1: Services Tags: Web design, logo design, print design, etc etc. Category 2: Type of clients Tags: small businesses, large companies So each post will be tagged with one or more tags from Category 1, and one tag from Category 2. However, I heard that using more than one Category per post is a bad idea in terms of SEO? But then, how can I go about it? I don't want any SEO penalties, but I will need to somehow categorize each post using these 2 distinct categories. Should I create some custom taxonomies? That seems like an overkill to me. The solution is probably something rather simple but it just escapes me. I'm not very experienced with taxonomies so I'll appreciate any suggestions.

• How do I detect a loop in this linked list?

  - by jjujuma

  Say you have a linked list structure in Java. It's made up of Nodes: class Node { Node next; // some user data } and each Node points to the next node, except for the last Node, which has null for next. Say there is a possibility that the list can contain a loop - i.e. the final Node, instead of having a null, has a reference to one of the nodes in the list which came before it. What's the best way of writing boolean hasLoop(Node first) which would return true if the given Node is the first of a list with a loop, and false otherwise? How could you write so that it takes a finite amount of space and a reasonable amount of time?

• Why do Pascal control structures appear to be inconsistent?

  - by 70Mike

  Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

• Mimic property/list changes on an object on another object

  - by soundslike

  I need to mimic changes (property/list) changes on an object and then apply it to another object to keep the structure/property the same. In essence it's like cloning etc. the biz rules require certain properties to not be applied to the other object, so I can't just clone the object otherwise this would be easy. I've already walked the source object to get INotifyPropertyChanged and IListChanged events, so I have the "source" and the args (Property or List) changed event notifications. Given that I guess I could build a reflection "hierarchy path" starting from the top level of the source object to get to the Property or List changed "source" (which could be several levels deep). Ignoring for the moment that certain object properties should not propagate to the other object, what's a way to build this "path"? Is a brute force top level down to build the "path" (and discard on the way back up if we don't hit the original changed event "source") the only way to do it? Any clever ideas on how to mimic changes from one object to another object?

• Git Status Across Multiple Repositories on a Mac

  - by eapen

  I have been searching for a solution to this for a while and have not found quite what I need. I have several Git Repositories in a folder on my Mac (OSX 10.6) and would like a script or tool that will loop through all the repositories and let me know if any of them needs "commit"-ing. This is my structure Sites   /project1   /project2   /project3 I want the tool to do a "git status" in Sites/project1, Sites/project2, Sites/project3 and let me know if Sites/project2 and Sites/project3 have changes or new files and needs to be Staged/committed The closest script I found that might be hackable is here: http://gist.github.com/371828 but even that script wouldn't run and I get an error: "syntax error near unexpected token `do" which might have been written for *nix.

• Check whether Excel file is Password protected

  - by Torben Klein

  I am trying to open an Excel (xlsm) file via VBA. It may or may not be protected with a (known) password. I am using this code: On Error Resume Next Workbooks.Open filename, Password:=user_entered_pw opened = (Err.Number=0) On Error Goto 0 Now, this works fine if the workbook has a password. But if it is unprotected, it can NOT be opened. Apparently this is a bug in XL2007 if there is also workbook structure protection active. (http://vbaadventures.blogspot.com/2009/01/possible-error-in-excel-2007.html). On old XL2003, supplying a password would open both unprotected and password protected file. I tried: Workbooks.Open filename, Password:=user_entered_pw If (Err.Number <> 0) Then workbooks.open filename This works for unprotected and protected file. However if the user enters a wrong password it runs into the second line and pops up the "enter password" prompt, which I do not want. How to get around this?

• C++ Class Inheritance architecture - preventing casting

  - by Some One

  I have a structure of base class and a couple of inherited classed. Base class should be pure virtual class, it should prevent instantiation. Inherited classes can be instantiated. Code example below: class BaseClass { public: BaseClass(void); virtual ~BaseClass(void) = 0; }; class InheritedClass : public BaseClass { public: InheritedClass1(void); ~InheritedClass1(void); }; class DifferentInheritedClass : public BaseClass { public: DifferentInheritedClass(void); ~DifferentInheritedClass(void); }; I want to prevent the following operations to happen: InheritedClass *inherited1 = new InheritedClass(); DifferentInheritedClass *inherited2 = new DifferentInheritedClass (); BaseClass *base_1 = inherited1; BaseClass *base_2 = inherited2; *base_1 = *base_2;

• When to alter a function vs when to just write a new one...?

  - by Andrew Heath

  /is n00b Through the gift of knowledge and expertise encoded here, I am doing my best to avoid n00b mistakes as I learn the basics of programming. I use functions when I (think I) can in PHP, and keep them somewhat sorted in different includes. The n00b problem I'm running into now is situations where perhaps 4/5th of an existing function is relevant to a new need. Maybe there are a slightly different set of inputs, or an additional calculation or two in the series, or output needs a different format/structure... but the core of the function is still applicable. Is there a good rule of thumb regarding when one should bolt-on crap to an original function and when one should (literally) copy & paste most of it into a new function and tweak to fit the situation? On the one hand I feel bad duping code, on the other I feel bad cluttering up an existing function with stuff not always needed...
