• Send bulk email from SQL Server 2008

  - by dbnewbie

  Hi, I am relatively new to databases,so please forgive me if my query sounds trivial. I need to send bulk email to all the contacts listed in a particular table. The body of the email is stored in a .doc file which begins as Dear Mr. _. The SQL server will read this file, append the last name of the contact in the blank space and send it to the corresponding email address for that last name. Any thoughts on how to proceed with this? Any insights,suggestions,tips will be greatly appreciated. Thanks!

• Sharing memory among YACC, Lex, and C files

  - by sczizzo

  I have a YACC (Bison) grammar, a Lex (Flex) tokenizer, and a C program among which I need to share a struct (or really any variable). Currently, I declare the actual object in the grammar file and extern it wherever I need it (which is to say, my C source file), usually using a pointer to manipulate it. I have a shared header (and implementation) file between the C file and the grammar file with functions useful for manipulating my data structure. This works, but it feels a little uncomfortable. Is there a better way to share memory between the grammar and program?

• TextToSpeech setOnUtteranceCompletedListener always returns -1 error?

  - by Robert Nekic

  I've been working with Android's TTS functions with general success however, one piece of it refuses to work for me; I can not successfully assign an OnUtteranceCompletedListener to my TextToSpeech object. I've tried implementing OnUtteranceCompletedListener in one of my classes and I've tried creating a new, stand-alone OnUtteranceCompletedListener instance. Both approaches are simple enough to implement and appear to yield proper listeners without exceptions...yet setOnUtteranceCompleteListener(myListener) ALWAYS returns -1 (ERROR). The documentation for this seems straight forward. Has anyone gotten this to work? I'm targeting SDK 4. Are there known issues with this with SDK4/v1.6?

• Why won't the VisualVM Profiler profile my application?

  - by Luke

  I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

• fast algorithm to sort very small set

  - by aaa

  hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions only. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

• Best Method for Minimizable Fullscreen Window

  - by kaykun

  Hi, I'm coding a short game in C++ and Win32, and I want to be able to make it in fullscreen with a fixed size. I also want the user to be able to switch focus between the game window and other windows as much as he/she wants without any weird screen glitches. So far I know of the ChangeDisplaySettings function and creating the window with the WS_POPUP style at initialization to make it fullscreen. To detect the user switching focus to other windows by way of alt+tab or otherwise, what messages should I be handling on the window's WndProc or should I be using another function? When loss of focus is detected should I only call ChangeDisplaySettings(NULL, 0); or are there other functions I should call as well? And what method should I use to handle focus back into the window? Also can anyone give me some info on how to make it work smoothly for different screen sizes? Thanks for any help.

• Data Structure Behind Amazon S3s Keys (Filtering Data Structure)

  - by dimo414

  I'd like to implement a data structure similar to the lookup functionality of Amazon S3. For those of you who don't know what I'm taking about, Amazon S3 stores all files at the root, but allows you to look up groups of files by common prefixes in their names, therefore replicating the power of a directory tree without the complexity of it. The catch is, both lookup and filter operations are O(1) (or close enough that even on very large buckets - S3's disk equivalents - both operations might as well be O(1))). So in short, I'm looking for a data structure that functions like a hash map, with the added benefit of efficient (at the very least not O(n)) filtering. The best I can come up with is extending HashMap so that it also contains a (sorted) list of contents, and doing a binary search for the range that matches the prefix, and returning that set. This seems slow to me, but I can't think of any other way to do it. Does anyone know either how Amazon does it, or a better way to implement this data structure?

• An expression of non-boolean type specified in a context where a condition is expected, near 'END'.

  - by Mike Keller

  So maybe someone can point me in the right direction of what is causing this error? I've been fighting with this for a couple of hours and searching the web, and I can't figure out what I'm doing wrong here. It's included as part of a stored procedure, I don't know if that matters, if it does I can include that as well. Tables and field names have been changed to protect the innocent... meaning my job. Thanks. SELECT /* The fields are here*/ FROM /* my joins are here */ WHERE (Table.Field = stuff) AND (Table.Field2 = otherstuff) AND (Table2.Field3 = someotherstuff) AND CASE @param1 WHEN 0 THEN 'Table.Field IS NULL' WHEN 1 THEN 'Table.Field2 IS NOT NULL' ELSE '' END

• C# settings using ApplicationSettingsBase - roaming and common

  - by Mark Pim

  I'm using the Windows Forms Application settings architecture (or however you're supposed to refer to it) and am successfully saving user settings to AppData. What I want to do is have some settings common to all users of a particular machine and some settings which roam with users across machines. For example I have some settings relating to a peripheral attached to the computer (model, settings etc.) and some user preferences like user interface colours. The colours preferences should roam with the user, but the peripheral settings should stay on the local computer no matter who's logged on. How can I mark these types of settings so that some get stored in /AppData/... and some in /AppData? Note that I don't want Application level settings - each computer the app will be installed on will have different settings. I'm targetting .Net 3.0 if that makes a difference.

• jquery dynatree class methods

  - by Jj Zhang

  I'm a new user of dynatree plugin. When I read the documentation, I found the list of tree and node class member functions, such as tree.getRoot(), node.countChildren().

• ASP with Crystal Report 9 hangs on .NET framework 3.5

  - by Chris Yang

  We have an ASP (not ASP.NET) application running on Windows 2003 server. One of the functions of the application is to generate reports using Crystal Report 9. It has been working without any problem with .NET Framework 2.0 and now it is required to install .NET Framework 3.5 SP1 on the server but after we installed the 3.5 SP1, every time we run the application the Crystal report is not generated and the web page hangs so we have to recycle the application pool in IIS to get the application back going. Does anyone have any idea/solution to this problem? Any help will be greatly appreciate.

• Using LINQ to SQL with multiple databases

  - by Stuart Ferguson

  I am working on a new project and hoping to use LINQ to SQL for the data access but have come across the following issue. I need to have my application access 3 databases with similar but not the same table structure, for example Database1 and Database 2 has a table called tblCustomer with 2 columns CustomerKey and CustomerName Database2 has a table called tblCustomer with 3 columns CustomerKey, CustomerName and CustomerPostCode I am looking for a solution that will allow me a query all three databases without the need for 3 GetCustomerList functions as Database1 and Database2 could use the same function as are the same structure, with an override function for database 3 to bring back the additional field. Is there a way i can declare a base datacontext class to handle Database 1 and 2 with an inherited version for Database 3. Thanks In Advance Stuart Ferguson

• Problem using SQLDMO/Vb6 against SQL Server 2008

  - by E.J. Brennan

  I have a client, that uses SQLDMO for a portion of a custom application that was written against SQL Server 2000, and they recently upgraded to SQL Server 2008. The majority of the app still runs fine (doesn't use SQLDMO), but the admin functions which rely on SQLDMO stopped working. I installed the SQL2005 backward compatibility pack, and now SQLDMO partially works, i.e. I can run "select" type queries, but any "Update" queries fail with the error message: to connect to the server you must use SQL Server management studio or sql server management objects (SMO) Any thoughts? Should the backward compatibility pack give me ALL the functionality back, or is this a known issue? BTW: I realize SQLDMO has been deprecated and will go away next release, none-the-less I need to do what I can to solve the problem at hand.

• Security flaw in this code approach

  - by Alec Smart

  Hello, Am wondering if there would be any security flaw in this approach. I am writing a piece of code which allows users to upload files and another set to download those files. These files can be anything. User uploads the file (any file including .php files), it is renamed to an md5 hash (extension removed) and stored on server. A corresponding mySQL entry is made. The user trying to download the file, uses say download.php to download the file where the md5 file is sent (with the original name). Is there someway in which anyone can exploit the above scenario?

• Python 3: timestamp to datetime: where does this additional hour come from?

  - by Beau Martínez

  I'm using the following functions: # The epoch used in the datetime API. EPOCH = datetime.datetime.fromtimestamp(0) def timedelta_to_seconds(delta): seconds = (delta.microseconds * 1e6) + delta.seconds + (delta.days * 86400) seconds = abs(seconds) return seconds def datetime_to_timestamp(date, epoch=EPOCH): # Ensure we deal with `datetime`s. date = datetime.datetime.fromordinal(date.toordinal()) epoch = datetime.datetime.fromordinal(epoch.toordinal()) timedelta = date - epoch timestamp = timedelta_to_seconds(timedelta) return timestamp def timestamp_to_datetime(timestamp, epoch=EPOCH): # Ensure we deal with a `datetime`. epoch = datetime.datetime.fromordinal(epoch.toordinal()) epoch_difference = timedelta_to_seconds(epoch - EPOCH) adjusted_timestamp = timestamp - epoch_difference date = datetime.datetime.fromtimestamp(adjusted_timestamp) return date And using them with the passed code: twenty = datetime.datetime(2010, 4, 4) print(twenty) print(datetime_to_timestamp(twenty)) print(timestamp_to_datetime(datetime_to_timestamp(twenty))) And getting the following results: 2010-04-04 00:00:00 1270339200.0 2010-04-04 01:00:00 For some reason, I'm getting an additional hour added in the last call, despite my code having, as far as I can see, no flaws. Where is this additional hour coming from?

• C# and T-SQL command-line Utility

  - by Chad Sellers

  Group, Part 1: I'm currently working on a command line utility that can take args and update a local database. The only issue I have is once i established a "Data connection"..how can I use those args for queries and searches. For example: ~//arrInput.exe "parm1" "pram2" "pram3" Part 2: I would like to take in command line args and use them as input parms for a "stored proc". Once finished execution....used the same inputs crate a log file. For example output file: mm-dd-yyyy hh:mm:ss - pram1,pram2,... pram1: updated/failed pram2: update/failed Thanks, Chad

• Why array size in llvm created by llvm's internal tools is not good enough for llvm?

  - by vava

  I'm getting strange error message from the following code: ArrayType * arrayType = ArrayType::get(Type::getInt32Ty(ctx), 0); stack = builder->CreateAlloca(arrayType, ConstantArray::get(arrayType, std::vector<Constant *>())); This code compiles fine but it gives me llvm::Value* getAISize(llvm::LLVMContext&, llvm::Value*): Assertion `Amt-getType() == Type::getInt32Ty(Context) && "Malloc/Allocation array size is not a 32-bit integer!"' failed. during execution. What's interesting, is that I never said of what type array size should be, it was created somewhere inside helper functions. So I naturally see no good reason for assert to be there. But I must be doing something wrong anyway, can you help me spot the problem? Thanks in advance. PS. LLVM, as good as it is, lacking documentation tremendously.

• JavaScript setTimeout setInterval within one function

  - by dagoof

  I think I might be overtired but I cannot for the life of me make sense of this, and I think it's due to a lack of knowledge of javascript var itv=function(){ return setInterval(function(){ sys.puts('interval'); }, 1000); } var tout=function(itv){ return setTimeout(function(){ sys.puts('timeout'); clearInterval(itv); }, 5500); } With these two functions I can call a=tout(itv()); and get a looping timer to run for 5.5 seconds and then exit, essentially. By my logic, this should work but it simply is not var dotime=function(){ return setTimeout(function(){ clearInterval(function(){ return setInterval(function(){ sys.puts("interval"); }, 1000); }); }, 5500); } any insight in this matter would be appreciated.

• Java simple encryption

  - by Ran

  Hello, I would like to encrypt a textual (configuration) file stored on disk. Trying to use DES encryption I've had fatal error on client machines, I later found out caused because the algorithm could not handle accented characters (!) I suspect that was because I was using old packages (sun.misc.BASE64Decoder) - but I'm not sure that is the reason. However, I'm looking for a simpler solution - I need a really simple encryption (I know some people would not agree on that) - not RSA of 128 bit keys or so, just obscuring the text from curious eyes. It is really weird that I could not find on the web a simple trivial solution. Any idea, anyone ? Thanks, Ran

• Execute a function when a <link> element has finished loading

  - by nornagon

  I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

• JavaScript: Keeping track of eventListeners on DOM elements

  - by bobthabuilda

  What is the best way to keep track of eventListener functions on DOM elements? Should I add a property to the element which references the function like this: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; elem.listeners = { click: [clickFn, function(){}] }; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Or should I store it in my own variable in my code like below: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; // Using window for the sake of brevity, otherwise I wouldn't =D // DOM elements and their listeners are referenced here in a paired array window.listeners = [elem, { click: [clickFn, function(){}] }]; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Obviously the second method would be less obtrusive, but it seems it could get intensive iterating through all those possibilities. Which is the best way and why? Is there a better way?

• is it possible to issue dynamic include in asp-classic?

  - by opensas

  I mean, like php'h include... something like my_file_to_be_included = "include_me.asp" -- for what I've seen so far, there are a couple of alternatives, but every one of them has some sort of shortcoming... what I'm trying to figure out is how to make a flexible template system... without having to statically include the whole thing in a single file with a loooooong case statement... here there are a couple of links a solution using FileSysmemObject, just lets you include static pages idem yet another one same thing from adobe this approach uses Server.Execute but it has some shortcomings I'd like to avoid... seems like (haven't tried yet) Server.Execute code runs in another context, so you can't use it to load a functions your are planning to use in the caller code... nasty... same thing I think this one is the same this looks promising!!! I'm not sure about it (couldn't test it yet) but it seems like this one dinamycally handles the page to a SSDI component... any idea???

• Checking to see if a generic class is inherited from an interface

  - by SnOrfus

  I've got a class that inherits from an interface. That interface defines an event that I'd like to subscribe to in the calling code. I've tried a couple of things, but they all resolve to false (where I know it's true). How can I check to see if a class implements a specific interface. Here's what I've tried (note, the object in question is a usercontrol that implements MyInterface, stored in an array of controls, only some of which implement MyInterface - it is not null): if (this.controls[index].GetType().IsSubclassOf(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType().IsAssignableFrom(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType() == typeof(MyInterface)) ((MyInterface)this.controls[index]).Event += this.Handler; All to no avail.
