  • Inline Conditional Statement in Stored Procedure

    - by Jason
    Here is the pseudo-code for my inline query in my code: select columnOne from myTable where columnOne = '#variableOne#' if len(variableTwo) gt 0 and columnTwo = '#variableTwo#' end I would like to move this into a stored procedure but am having trouble building the query correctly. I assume it would be something like select columnOne from myTable where columnOne = @variableOne CASE WHEN len(@variableTwo) <> 0 THEN and columnTwo = @variableTwo END This is giving me a syntax error. Could someone tell me what I've got wrong. Also, I would like to keep it to only one query and not just have one if statement. Also, I do not want to build the sql in the stored procedure and run Exec() on it.

  • How do I return the rows from an Oracle Stored Procedure using SELECT?

    - by Calanus
    I have a stored procedure which returns a ref cursor as follows: CREATE OR REPLACE PROCEDURE AIRS.GET_LAB_REPORT (ReportCurTyp OUT sys_refcursor) AS v_report_cursor sys_refcursor; report_record v_lab_report%ROWTYPE; l_sql VARCHAR2 (2000); BEGIN l_sql := 'SELECT * FROM V_LAB_REPORT'; OPEN v_report_cursor FOR l_sql; LOOP FETCH v_report_cursor INTO report_record; EXIT WHEN v_report_cursor%NOTFOUND; END LOOP; CLOSE v_report_cursor; END; I want to use the output from this stored procedure in another select statement like: SELECT * FROM GET_LAB_REPORT() but I can't seem to get my head around the syntax. Any ideas?

  • How can I use linq to build an object from 1 row of data?

    - by Hcabnettek
    Hi All, I have a quick linq question. I have a stored proc that should return one row of data. I would like to use a lambda to build an object. Here's what I'm currently doing which works, but I know I should be able to use First instead of Select except I can't seem to get the syntax correct. Can anyone straighten me out here? Thanks for any help. var location = new GeoLocationDC(); DataSet ds = db.ExecuteDataSet(dbCommand); if(ds.Tables[0].Rows.Count == 1) { var rows = ds.Tables[0].AsEnumerable(); var x = rows.Select( c => new GeoLocationDC { Latitude = Convert.ToInt32(c.Field<string>("LATITUDE")), Longitude = Convert.ToInt32(c.Field<string>("LONGITUDE")) }).ToList(); if(x.Count > 0 ) { location = x[0]; } Cheers, ~ck }

  • Update Facebook Page's status using pyfacebook

    - by thornomad
    I am attempting to add functionality to my Django app: when a new post is approved, I want to update the corresponding Facebook Page's status with a message and a link to the post automatically. Basic status update. I have downloaded and installed pyfacebook - and I have read through the tutorial from Facebook. I have also seen this suggestion here on SO: import facebook fb = facebook.Facebook('YOUR_API_KEY', 'YOUR_SECRET_KEY') fb.auth.createToken() fb.login() # THIS IS AS FAR AS I CAN GET fb.auth.getSession() fb.set_status('Checking out StackOverFlow.com') When I get to the login() call, however, pyfacebook tries to open lynx so I can login to Facebook 'via the web' -- this is, obviously, not going to work for me because the system is supposed to be automated ... I've been looking, but can't find out how I can keep this all working with the script and not having to login via a web browser. Any ideas?

  • Lazy evaluation with ostream C++ operators

    - by SavinG
    I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

  • Software Protection: Shuffeling my application?

    - by Martijn Courteaux
    Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

  • Accessing form's resources (resx file) from code

    - by kzen
    If I have a form Frm1.cs that is using some icons, images or other resources, these resources get stored in the form's resx file (Frm1.resx). My simple question is how do I access these resources from code? As a workaround I can store these resources in the Project resource file and they will be available via Properties.Resources.resourcename. However, similar syntax does not work for the resources stored in the form's resource file. While searching for a solution I have come across several references to ResourceManager class but was not able to find a way to use that to access the form's resources...

  • WYSIWYG text editor in Java

    - by Aaron Digulla
    I'd like to collect all WYSIWYG text editors for Java here. Some rules for entries: There must be a link to the project/product You must state whether it's open source or commercial Is it possible to extend the editor (add new features like a "violet centered sudoku")? Is that simple or complex? Does it come with lots of features (fancy character and paragraph styles with online spell checking for several languages in the same document) or just the basics (bold, italics, no underline)? List important dependencies (does it run on bare Java with Swing? SWT? MacOS?) Your personal opinion This list should help developers determine which editor to choose. I'm not looking for "the best" but more "what's there".

  • Crystal Report Function for converting Seconds to Timespan format.

    - by arakkots
    I have a crystal report where it shows the Agent's activities throughout the day with a pie chart. In the details section it is displaying: Activity [string] StartedAt [DateTime] EndedAt [DateTime] Duration [The difference between EndedAt and StartedAt in seconds - Integer] Report data is GroupedBy Activity and summarized by Duration. Currently Duration is shown in seconds but I need to format it 02h:30m:22s:15ms. For that I wrote a custom function in Crystal Report in the Formula Workshop editor as follows, but it looks like the syntax is not right (Error message on keyword Long: "A variable type (for example, 'String') is missing."). Can someone help? Function GetTimeSpanString(seconds as Long) Dim ts As TimeSpan = TimeSpan.FromSeconds( seconds ); GetTimeSpan = string.Format("{0:D2}h:{1:D2}m:{2:D2}s:{3:D3}ms", ts.Hours, ts.Minutes, ts.Seconds, ts.Milliseconds) End Function

  • How do I programmatically set property of control in aspx file ?

    - by Thomas Wanner
    This may be a very dumb question but I can't seem to get it working. I use at many places the following syntax for dynamically binding a property of a control in aspx file to the resource entry, e.g. <SomeFunnyControl Text="<%$ Resources : ResClass, ResEntry %>" /> I want to do a similar thing with a class containing some constants, something like <SomeFunnyControl Text="<%= MyConstantsClass.MyStringConstant %>" /> But this doesn't seem to work, it simply sets the text to the exact expression without evaluating it. I am using ASP.NET 3.5 btw. I have tried the databinding approach but I get an HttpParseException saying Databinding expressions are only supported on objects that have a DataBinding event.

  • How to prevent the beep sound caused by alt key pressed in a WinForms TextBox?

    - by Michael Johnson
    I'm creating a routine that allows the user to replicate keyboard shortcuts into a textbox for 'custom keyboard shortcuts' customization, but every time the alt key is pressed with another letter, it produces another sound. I'm capturing the keys in the textbox_keydown event to parse the modifiers + other keys into a readable Shift + A or Ctrl + Shift + B manner into that very same textbox. Should I be doing this in a different event like textbox_previewkey instead of textbox_keydown? How can I prevent the alt modifier key + a letter or number causing the Beep sound? the textbox is just a normal .net 3.5 textbox with the only edited properties of it being the ReadOnly property to false. Is there a better way I could re-do this? I'm currently just checking that if any modifiers keys are pressed and then + a-z or 0-9, then to go ahead and input the appropriately pressed keys into that same textbox like Shift + A or Ctrl + Shift + Y.

  • js regexp problem

    - by Alexander
    I have a searching system that splits the keyword into chunks and searches for it in a string like this: var regexp_school = new RegExp("(?=.*" + split_keywords[0] + ")(?=.*" + split_keywords[1] + ")(?=.*" + split_keywords[2] + ").*", "i"); I would like to modify this so that so that I would only search for it in the beginning of the words. For example if the string is: "Bbe be eb ebb beb" And the keyword is: "be eb" Then I want only these to hit "be ebb eb" In other words I want to combine the above regexp with this one: var regexp_school = new RegExp("^" + split_keywords[0], "i"); But I'm not sure how the syntax would look like. I'm also using the split fuction to split the keywords, but I dont want to set a length since I dont know how many words there are in the keyword string. split_keywords = school_keyword.split(" ", 3); If I leave the 3 out, will it have dynamic lenght or just lenght of 1? I tried doing a alert(split_keywords.lenght); But didnt get a desired response

  • Is there any short way to load data to the properties of a class, for each column name matching the properties of the class?

    - by Ugur Gümüshan
    I want to load data to an instance of an object using its constructor and I write $this->property=$row["colname"] each time for each property. the mysql_fetch_object function fetches the data as an object but I am not sure if the instance of an object can be assigned to some object from inside. othwerwise I would use __construct($object) { $this=$object; } //doesn't give any syntax error Maybe I should look into iteration of properties and use foreach($object as $key => $value) $value=$object[$key]; or can I assign like $this=$object; within the constructor?

  • Mac OS X: Best way to do runtime check for retina display?

    - by Todd Ditchendorf
    Given a Cocoa application which runs on Mac OS X 10.7 and later: What is the best way to check, at runtime, if your app is currently running on a Mac with at least one retina display attached? If checking for this sort of thing is just really wrong-headed, I fully welcome a well-reasoned explanation of why. But I'd still like to know :). It seems likely you could just do a check specifically for the new Mac Book Pro "Retina" hardware (the only Mac at this time which currently has a retina display), but ideally, I'd really prefer a more general/generic/future-proof way to check than this. Ideally, I'd like to know how to detect the retina display, not the specific Mac model which currently happens to ship with a retina display.

  • hibernate versioning parent entity

    - by Priit
    Consider two entities Parent and Child. Child is part of Parent's transient collection Child has a ManyToOne mapping to parent with FetchType.LAZY Both are displayed on the same form to a user. When user saves the data we first update Parent instance and then Child collection (both using merge). Now comes the tricky part. When user modifies only Child property on the form then hibernate dirty checking does not update Parent instance and thus does not increase optimistic locking version number for that entity. I would like to see situation where only Parent is versioned and every time I call merge for Parent then version is always updated even if actual update is not executed in db.

  • Conditional Regex Replace in C# without MatchEvaluator

    - by Buttink
    So, Im trying to make a program to rename some files. For the most part, I want them to look like this, [Testing]StupidName - 2[720p].mkv But, I would like to be able to change the format, if so desired. If I use MatchEvaluators, you would have to recompile every time. Thats why I don't want to use the MatchEvaluator. The problem I have is that I don't know how, or if its possible, to tell Replace that if a group was found, include this string. The only syntax for this I have ever seen was something like (?<group>:data), but I can't get this to work. Well if anyone has an idea, im all for it.

  • For Qt 4.6.x, how to auto-size text to fit in a specified width?

    - by darenchow
    Inside of my QGraphicsRectItem::paint(), I am trying to draw the name of the item within its rect(). However, for each of the different items, they can be of variable width and similarly names can be of variable length. Currently I am starting with a maximum font size, checking if it fits and decrementing it until I find a font size that fits. So far, I haven't been able to find a quick and easy way to do this. Is there a better, or more efficient way to do this? Thanks! void checkFontSize(QPainter *painter, const QString& name) { // check the font size - need a better algorithm... this could take awhile while (painter->fontMetrics().width(name) > rect().width()) { int newsize = painter->font().pointSize() - 1; painter->setFont(QFont(painter->font().family(), newsize)); } }

  • UITableView loading before variables being set

    - by Sheehan Alam
    I have a label on a UITableView. When clicked it will refresh my tableview and set the top cell's height. When I am setting the cell height, I am checking if a certain variable is TRUE. If true it will show the large height, if false, the smaller height. At the time of cell height creation, my variable is always false. It is a member variable and its value is being set when the user clicks on the label. How can I make sure that the variable is set before the table refreshes?

  • Calculating terrain height in 3d-space

    - by Jonas B
    Hi I'm diving into 3d programming a bit and am currently learning by writing a procedural terrain generator that generates terrain based on a heightmap. I would also want to implement some physics and my first attempt at terrain collision was by simply checking the current position vs the heightmap. This however wont work well against small objects as you'd have to calculate the height by taking the heightdifference of the nearest vertices of the object and doing this every colision check is pretty slow. Beleive me I tried googling for it but there's simply so much crap and millions of blogs posting ripped-of newbie tutorials everywhere with basically no real information on the subject, I can't find anything that explains it or even names any generally used techniques. I'm not asking for code or a complete solution, but if anyone knows a particular technique good for calculating a high-res heightmap out of the already generated and smoothed terrain I would be very happy as I could look into it further when I know what I'm looking for. Thanks
