• None of my Win Forms buttons work

  - by nectarines

  I have a windows form which connects to a SQL Server though a dataset. The form was working fine since my last compile. All of a sudden, none of my buttons work! The data is loaded on the form, all the tabs work fine, drop down boxes work fine, but the buttons are literally unresponsive to any clicks. I added a test button and I get the same results. I can visually see the button getting clicked but no events. Any ideas?

• How do I create custom Controls for my VS2005 toolbox?

  - by end-user

  Ok, this question might more about design theory. I have successfully created controls that show up in my toolbox, so I'm pretty sure I have the process right. Also, my "AutoToolboxPopulate" is set to true, so things are showing up as I create them. My question is this: I'm sub-classing a native Control for specialized use. When I derive my class from an exposed concrete class, such as BulletedList, my custom Control appears in my Toolbox. However, when I drop it back to the parent, such as ListControl, my Control is not listed (actually it's grayed out when I "List All"). What am I missing?

• Generating incremental numeric column values during INSERT SELECT statement

  - by Charles

  I need to copy some data from one table to another in Oracle, while generating incremental values for a numeric column in the new table. This is a once-only exercise with a trivial number of rows (100). I have an adequate solution to this problem but I'm curious to know if there is a more elegant way. I'm doing it with a temporary sequence, like so: CREATE SEQUENCE temp_seq START WITH 1; INSERT INTO new_table (new_col, copied_col1, copied_col2) SELECT temp_seq.NEXTVAL, o.* FROM (SELECT old_col1, old_col2 FROM old_table) o; DROP SEQUENCE temp_seq; Is there way to do with without creating the sequence or any other temporary object? Specifically, can this be done with a self-contained INSERT SELECT statement? There are similar questions, but I believe the specifics of my question are original to SO.

• html links & hover events over certain locations on an image.

  - by Tommy

  So i created a web site a long time ago using a designer alot like frontpage + expression design put together, and since then Ive gotten more into coding, and I'm learning html, CSS, and all that good stuff.. and i have this re-designed header that Ive made here: http://prntscr.com/8zct So what I need to know, is how i can get it so that when a user clicks on one of the links in the header design it will redirect to a page. and also if possible, how to make it so when a user hovers over a link a drop down may appear with other options. As me being quite new to this sort of stuff, could anybody help me achieve this? PS. I'm working in Visual Studio with ASP. but that doesn't change anything about the html and css stuff. just letting you guys know.

• Is there a Silverlight week picker control?

  - by Jason Young

  We have a report that compares data between weeks, and it seems like this is the exception and not the rule in the reporting world. I'm looking for an elegant way of selecting "a week" in a Silverlight control. I'd prefer not to spend the time building it ourselves, so it would be nice if I could buy a well polished control that does this. Sure, I could use a drop down list, but I would like a way to easily navigate through potentially years worth of weeks. Any existing controls out there? Any clever ways of using basic controls to achieve our goal? Thank you!

• Co-opt popular abandonware opensource project? Thoughts?

  - by Mike Bouck

  Here's the scenario: A popular open source project is used/loved by many but has become stale due to the fact that the last drop came out nearly a year ago. Many bugs/feature requests/fixes have been logged in the interim and everyone is getting by via downloading the trunk and building custom/private builds with the changes incorporated. The copyright is simple -- there is none and the code is in the public domain. The project owner spins the project as community open source and has setup a sourceforge site, but to date (5 years running now) has yet to accept one contributor. In otherwords the "community" is a community of one. The project owner takes great pride in the project and has obviously contributed a lot of time/effort but for whatever reason has has seemingly abandoned the project and is unresponsive when offers of help are made. So, the question, should the community fork the codebase, setup a new community site, and take matters in their own hands?

• Mysql: how do I make an exact working copy of a table?

  - by epo

  I am working on a restructuring of a legacy database and its associated applications. To keep old and new working in parallel I have created a development database and copied the tables of interest to it, e.g. create database devdb; drop table if exists devdb.tab1; CREATE TABLE devdb.tab1 like working.tab1; insert into devdb.tab1 select * from working.tab1; Having done this I notice that triggers affecting tab1 have not been copied over. Is there any way in which I can produce a working copy of tab1, i.e. data, permissions, triggers, everything?

• References/walkthroughs for maintaining database schemas with Visual Studio 2010?

  - by user206356

  I have Visual Studio 2010 Beta 2 and SQL Server 2008 installed. I'm working with a populated database and want to modify various column types. SQL Server Management Studio requires me to drop tables to do this, and get pretty finicky given my moderate level of knowledge of SQL Server. However, I heard the new database project type supports changing the database schema to the desired format and it will handle creating and running all the scripts to implement the changes. I've created a VS2010 database project using the existing database as the source, but so far haven't had much luck figuring out the appropriate method to make the changes without getting an error. As a result, I'm looking for any reference info I can find on using VS2010's capabilities in this area. Any suggestions?

• LINQ to SQL DB Connections not closing

  - by Joe

  I am using LINQ to SQL in an asp.net mvc application. I am calling stored procedures via ajax calls. The active connections for 2-3 users goes to 100 active connections. and then server timeouts happen. I then used IOC -autofac to resuse the same repository that has a datacontext. now tho i get an active connection on the SQL server per loggedin user plus one. I have never seen this before. Why wouldnt Lin2sql not drop a connection when not in use? would calling a stored procedure in an ajax call in a loggedin session creat an a new active connection? Could a Stored Procedure with loops and or a waitfor hold open a connection??

• How can I create an enum using numbers?

  - by Jordan S

  Is it possible to make an enum using just numbers in C#? In my program I have a variable, Gain, that can only be set to 1, 2, 4, and 8. I am using a propertygrid control to display and set this value. If I were to create an enum like this... private enum GainValues {One, Two, Four, Eight} and I made my gain variable of type GainValues then the drop-down list in the propertygrid would only show the available values for the gain variable. The problem is I want the gain values to read numerically an not as words. But I can not create an enum like this: private enum GainValues {1,2,4,8} So is there another way of doing this? Perhaps creating a custom type?

• How to build a sentence parser using only the c++ standared library?

  - by CiM

  Hello everyone, I am designing a text based game similar to Zork, and I would like it to able to parse a sentance and draw out keywords such TAKE, DROP ect. The thing is, I would like to do this all through the standard c++ library... I have heard of external libraries (such as flex/bison) that effectively accomplish this; however I don't want to mess with those just yet. What I am thinking of implementing is a token based system that has a list of words that the parser can recognize even if they are in a sentence such as "take sword and kill monster" and know that according to the parsers grammar rules, TAKE, SWORD, KILL and MONSTER are all recognized as tokens and would produce the output "Monster killed" or something to that effect. I have heard there is a function in the c++ standard library called strtok that does this, however I have also heard it's "unsafe". So if anyone here could lend a helping hand, I would greatly appreciate it.

• What's a very easy C++ profiler (VC++)?

  - by John

  I've used a few profilers in the past and never found them particularly easy. Maybe I picked bad ones, maybe I didn't really know what I was expecting! But I'd like to know if there are any 'standard' profilers which simply drop in and work? I don't believe I need massively fine-detailed reports, just to pick up major black-spots. Ease of use is more important to me at this point. It's VC++ 2008 we're using (I run standard edition personally). I don't suppose there are any tools in the IDE for this, I can't see any from looking at the main menus?

• More swing design & actions

  - by takoi

  Im pretty new to gui programming so i've been reading through every post on this site about swing and design. Whats been answered over and over again is that one should have a class which handles all the action. Like this: (GUI being some JFrame) Now, this works great for one-way actions, like OpenDialog. But the actions for buttons in DialogA and B will have to have access to all the components (there will be many) in its dialog, and the controller. This is where im stuck. The only sane way i can see is to put it in DialogA/B but i would then need to pass the controller all the way down, through classes that dont even need it, and it'll get all spaghetti. Really dont want that. Someone must have encountered this problem before. So where should i put this Action? Or should i just drop the whole design?

• Using * Width & Precision Specifiers With boost::format

  - by John Dibling

  I am trying to use width and precision specifiers with boost::format, like this: #include <boost\format.hpp> #include <string> int main() { int n = 5; std::string s = (boost::format("%*.*s") % (n*2) % (n*2) % "Hello").str(); return 0; } But this doesn't work because boost::format doesn't support the * specifier. Boost throws an exception when parsing the string. Is there a way to accomplish the same goal, preferably using a drop-in replacement?

• PHP 5.3 Namespaces should i use every PHP function with backslash?

  - by lhwparis

  Hi, im now using namespaces in PHP 5.3 now there is a fallback mechanism for functions which dont exist in the namespace. so php every time checks if the function exists in namespace and then tries to load it from global space. So what about all php internal functions? strstr for example? Should i now use every php internal function with a \ ? to avoid php first checking the namespace? is this fallback a huge performance drop? what do you think?

• Process for Upgrading from RedBean 3.5 to RedBean 4

  - by Jay Haase

  I am currently using RedBean version 3.5. I think I would like to move to the latest version of RedBean, version 4. I have found no documentation about upgrade process and have a number of significant questions: Is my RedBean 3.5 database schema compatible 4, or will up have to migrate all of the tables to some new format? Is any of my RedBean 3.5 code compatible with version 4, or wouldI need to rewrite all of my code that uses RedBean 3.5? Would it make more sense to upgrade to Doctrine? As a side note, I am also feeling concerned about RedBean's drop of support for Composer, which I have found to be über helpful in managing the various versions of libraries I am using.

• How do I get the sequence of numbers in a sorted-set that are between two integers in clojure?

  - by Greg Rogers

  Say I have a sorted-set of integers, xs, and I want to retrieve all the integers in xs that are [x, y), ie. between x and y. I can do: (select #(and (>= % x) (< % y)) xs) But this is inefficient - O(n) when it could be O(log n), I expect the number of elements returned to be small. Using take-while and drop-while would let me exit once I've reached y, but I still can't jump to x efficiently. I am just learning clojure so here is how I would do it in C++: set<int>::iterator first = xs.lower_bound(x); set<int>::iterator last = xs.lower_bound(y); for (; first != last; ++first) // do something with *first Can I do this in clojure?

• How do I make TODO comments show up in the task list for C++ projects in Visual Studio 2010?

  - by Chris Simmons

  I'm trying to get my TODO comments to show up in the task list in Visual Studio 2010 for a C++ project, but they don't. I looked at this, but see no caveats other than the TODO comments need to be in the currently-open file. For example, creating a new Win32 console app places this: // TODO: reference additional headers your program requires here in a new file, stdafx.h. However, there's nothing in the task list. I have "Comments" chosen from the drop-down in the task list, but it's always empty. And it's not this problem; I can open the file and be looking at the TODO comment in the code editor and no task is shown. This is not a problem for C# projects as TODO comments show up as designed in those projects; this appears to be an issue specific to C++ projects. What else can I check?

• SQL Server 2005: When clicking "Add" database I keep getting 'verify that the path or file exists'

  - by Code Sherpa

  When I right click on "databases" in Sql Server 2005 Management Studio and then Attach... Add I get the following error: C:\Documents and Settings\Administrator\My Documents\SQL Server Management Studio\ Projects\Path\To\MDF\And\LDF\Files\ cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. The answer is easy - the MDF and LDF files where removed when Nant (by way of my dev machine) issued a drop command. But, after replacing the MDF and LDF files, I want to reattach the database but the above error keeps coming up when I select "Add". Also, I have already "unattached" the database in question and it no longer appears on the left under "databases". I have tried to replace a copy of the MDF and LDF files in the folder being referenced and that didn't work. Any ideas as to how to gracefully get rid of this error?

• Execute query stored in variable in a very specific way

  - by niao

  Greetings, I have a problem as follows: I have an SQL variable declared: DECLARE @myVariable nvarchar(max) a third party library set a value for this variable. To simplify, lets say that the value is as follows: SET @myVariable = 'Select ROWGUID from MySampleTable' Now, I want to execute the following query: SELECT ROWGUID FROM myTable WHERE ROWGUID in (exec sp_executesql @myVariable ) However, the above statement does not work because it returns an error telling me that I can't execute stored procedure in that way. I made a workaround and this is what I wrote: create table #temptable (ID uniqueidentifier null) if(@myVariable is not null AND @myVariable !='') insert into #temptable exec sp_executesql @myVariable SELECT ROWGUID FROM myTable WHERE ROWGUID in (select * from #temptable) DROP TABLE #temptable This works fine.However I don't think it is a good idea to use temporary table. How can I achieve the same result without necessity of creating temporary tables? I am using SQL SERVER 2005

• Possibly simple PHP/MYSQL issue with retrieving and showing data

  - by envoys

  I have been racking my brains over this for a while now. Here is the data i have in the sql data base as an example: ID | TYPE | DATA 1 | TXT | TEST 2 | PHP | php 3 | JS | JAVASCRIPT That is just an example, there are multiple listing for TXT, PHP and JS throughout the table. What I want to do is retrive all the data and display it all into separate drop down/select boxes. Meaning, select box one would list all data with type TXT, select box two would list all data with type PHP and select box 3 would list all data with type JS. The only way I have came about doing this is doing individual sql queries for each different type. I know there is a way to do it all in 1 query and then display it the way I want to but I just can't seem to figure out how and I know its going to drive me nuts when someone helps and I see just how they did it. Thanks for the input.

• How can I convince IE to simply display application/json rather than offer to download it?

  - by Cheeso

  While debugging jQuery apps that use AJAX, I often have the need to see the json that is being returned by the service to the browser. So I'll drop the URL for the JSON data into the address bar. This is nice with ASPNET because in the event of a coding error, I Can see the ASPNET diagostic in the browser: But when the server-side code works correctly and actually returns JSON, IE prompts me to download it, so I can't see the response. Can I get IE to NOT do that, in other words, to just display it as if it were plain text? I know I could do this if I set the Content-Type header to be text/plain. But this is specifically an the context of an ASPNET MVC app, which sets the response automagically when I use JsonResult on one of my action methods. Also I kinda want to keep the appropriate content-type, and not change it just to support debugging efforts.
