  • C# internal VS VBNET Friend

    - by Will Marcouiller
    To this SO question: What is the C# equivalent of friend?, I would personally have answered "internal", just like Ja did among the answers! However, Jon Skeet says that there is no direct equivalence of VB Friend in C#. If Jon Skeet says so, I won't be the one telling otherwise! ;P I'm wondering how can the keyword internal (C#) not be the equivalent of Friend (VBNET) when their respective definitions are: Friend VBNET The Friend (Visual Basic) keyword in the declaration statement specifies that the elements can be accessed from within the same assembly, but not from outside the assembly. [...] internal C# Internal: Access is limited to the current assembly. To my understanding, these definitions mean quite the same to me. Then, respectively, when I'm coding in VB.NET, I use the Friend keyword to specify that a class or a property shall be accessible only within the assembly where it is declared. The same in C#, I use the internal keyword to specify the same. Am I doing something or anything wrong from this perspective? What are the refinements I don't get? Might someone please explain how or in what Friend and internal are not direct equivalences? Thanks in advance for any of your answers!

  • Highlight image borders with Ajax request.

    - by Tek
    First, some visualization of the code. I have the following images that are dynamically generated from jquery. They're made upon user request: <img id="i13133" src="someimage.jpg" /> <img id="i13232" src="someimage1.jpg" /> <img id="i14432" src="someimage2.jpg" /> <img id="i16432" src="someimage3.jpg" /> <img id="i18422" src="someimage4.jpg" /> I have an AJAX loop that repeats every 15 seconds using jQuery and it contains the following code: Note: The if statement is inside the Ajax loop. Where imgId is the requested ID from the Ajax call. //Passes the IDs retrieved from Ajax, if the IDs exist on the page the animation is triggered. if ( $('#i' + imgId ).length ) { var pickimage = '#i' + imgId; var stop = false; function highlight(pickimage) { $(pickimage).animate({color: "yellow"}, 1000, function () { $(pickimage ).animate({color: "black"}, 1000, function () { if (!stop) highlight(pickimage); }); }); } // Start the loop highlight(pickimage); } It works great, even with multiple images. But I had originally used this with one image. The problem is I need an interrupt. Something like: $(img).click(function () { stop = true; }); There's two problems: 1.)This obviously stops all animations. I can't wrap my head around how I could write something that only stops the animation of the image that's clicked. 2.)The Ajax retrieves IDs, sometimes those IDs appear more than once every few minutes, which means it would repeat the animations on top of each other if the image exists. I could use some help figuring out how to detect if an animation is already running on an image, and do nothing if the animation is already triggered on an image.

  • Python and Unicode: How everything should be Unicode

    - by A A
    Forgive if this a long a question: I have been programming in Python for around six months. Self taught, starting with the Python tutorial and then SO and then just using Google for stuff. Here is the sad part: No one told me all strings should be Unicode. No, I am not lying or making this up, but where does the tutorial mention it? And most examples also I see just make use of byte strings, instead of Unicode strings. I was just browsing and came across this question on SO, which says how every string in Python should be a Unicode string. This pretty much made me cry! I read that every string in Python 3.0 is Unicode by default, so my questions are for 2.x: Should I do a: print u'Some text' or just print 'Text' ? Everything should be Unicode, does this mean, like say I have a tuple: t = ('First', 'Second'), it should be t = (u'First', u'Second')? I read that I can do a from __future__ import unicode_literals and then every string will be a Unicode string, but should I do this inside a container also? When reading/ writing to a file, I should use the codecs module. Right? Or should I just use the standard way or reading/ writing and encode or decode where required? If I get the string from say raw_input(), should I convert that to Unicode also? What is the common approach to handling all of the above issues in 2.x? The from __future__ import unicode_literals statement? Sorry for being a such a noob, but this changes what I have been doing for a long time and so clearly I am confused.

  • C: 8x8 -> 16 bit multiply precision guaranteed by integer promotions?

    - by craig-blome
    I'm trying to figure out if the C Standard (C90, though I'm working off Derek Jones' annotated C99 book) guarantees that I will not lose precision multiplying two unsigned 8-bit values and storing to a 16-bit result. An example statement is as follows: unsigned char foo; unsigned int foo_u16 = foo * 10; Our Keil 8051 compiler (v7.50 at present) will generate a MUL AB instruction which stores the MSB in the B register and the LSB in the accumulator. If I cast foo to a unsigned int first: unsigned int foo_u16 = (unsigned int)foo * 10; then the compiler correctly decides I want a unsigned int there and generates an expensive call to a 16x16 bit integer multiply routine. I would like to argue beyond reasonable doubt that this defensive measure is not necessary. As I read the integer promotions described in 6.3.1.1, the effect of the first line shall be as if foo and 10 were promoted to unsigned int, the multiplication performed, and the result stored as unsigned int in foo_u16. If the compiler knows an instruction that does 8x8-16 bit multiplications without loss of precision, so much the better; but the precision is guaranteed. Am I reading this correctly? Best regards, Craig Blome

  • Is NUnit's ExpectedExceptionAttribute only way to test if something raises an exception?

    - by Dariusz Walczak
    Hello, I'm completely new at C# and NUnit. In Boost.Test there is a family of BOOST_*_THROW macros. In Python's test module there is TestCase.assertRaises method. As far as I understand it, in C# with NUnit (2.4.8) the only method of doing exception test is to use ExpectedExceptionAttribute. Why should I prefer ExpectedExceptionAttribute over - let's say - Boost.Test's approach? What reasoning can stand behind this design decision? Why is that better in case of C# and NUnit? Finally, if I decide to use ExpectedExceptionAttribute, how can I do some additional tests after exception was raised and catched? Let's say that I want to test requirement saying that object has to be valid after some setter raised System.IndexOutOfRangeException. How would you fix following code to compile and work as expected? [Test] public void TestSetterException() { Sth.SomeClass obj = new SomeClass(); // Following statement won't compile. Assert.Raises( "System.IndexOutOfRangeException", obj.SetValueAt( -1, "foo" ) ); Assert.IsTrue( obj.IsValid() ); } Edit: Thanks for your answers. Today, I've found an It's the Tests blog entry where all three methods described by you are mentioned (and one more minor variation). It's shame that I couldn't find it before :-(.

  • Downloading attachments to directory with IMAP in PHP, randomly works

    - by Nick
    I found PHP code online to download attachments to a directory using IMAP from here. http://www.nerdydork.com/download-pop3imap-email-attachments-with-php.html I modified it slightly changing $structure = imap_fetchstructure($mbox, $jk); $parts = ($structure->parts); to $structure = imap_fetchstructure($mbox, $jk); $parts = ($structure); to get it to run properly, as otherwise I got an error about how stdClass doesn't define a property called $parts. Doing that, I was able to download all the attachments. I tested it again recently though, and it didn't work. Well, it didn't work 6 times, worked the 7th, and then hasn't worked since. I'm thinking it has something to do with me screwing up the parts handling, since count($parts) keeps returning 1 for each message, so it's not finding any attachments I think. Since it downloaded the attachments at one point with no issues, I feel confident that the area things are getting screwed up is right here. Before this block of code is a for loop that goes through each message in the box, and after it is loop that just goes through $parts for each imap structure. Thanks for any help you can provide. I looked at the imap_fetchstructure page on php.net and can't figure out what I'm doing wrong. Edit: I just double-checked the folder after typing up my question and it all popped up. I feel like I'm going nuts. I hadn't run the code since a few minutes before I started typing this, and it doesn't make sense to me that it would take this long to trigger. I have some 800 messages in the mailbox, but I figured since it printed my statement at the very end of the PHP that all of the file creation work was done.

  • LEFT OUTER JOIN with a WHERE clause

    - by Wesley
    I have two tables. indRailType contains a list of the names paired with an ID value that I use in other tables to indicate the rail type. WO_BreakerRail contains a date column and a rail code colume that corresponds to the same code in indRailType and some other data. There's a row in WO_BreakerRail for any activity on each rail type, for every date. So I could have 3 rows dated for 3/19/2010, each row indicates a different rail code, and what happened. When I use the following LEFT OUTER JOIN, I get a table with all the types of rail, with nulls in the rows where nothing happened on the 19th. Now, this is only working because I only have one date represented in my WO_BreakerRail table right now, the 19th. When I add more rows with different dates, things will go haywire. This is my SQL statement, which right now gives me exactly the results I want: SELECT WO_BreakerRail.ID, indRailType.RailType, WO_BreakerRail.CreatedPieces, WO_BreakerRail.OutsideSource, WO_BreakerRail.Charged, WO_BreakerRail.Rejected, WO_BreakerRail.RejectedToCrop FROM indRailType LEFT OUTER JOIN WO_BreakerRail ON indRailType.RailCode = WO_BreakerRail.RailCode Now, when I add in a WHERE WO_BreakerRail.Date = @Date clause I lose all the rows in the JOIN which nothing happened. I don't want that. From reading up, it sounds like a FULL OUTER JOIN is what I want, but SQL Server Compact Edition doesn't support FULL OUTER JOINs. Is there a way around this, or am I looking for something else entirely?

  • Search for a date between given ranges - Lotus

    - by Kris.Mitchell
    I have been trying to work out what is the best way to search for gather all of the documents in a database that have a certain date. Originally I was trying to use FTsearch or search to move through a document collection, but I changed over to processing a view and associated documents. My first question is what is the easiest way to spin through a set of documents and find if a date stored in the documents is greater than or less than a specified date? So, to continue working I implemented the following code. If (doc.creationDate(0) > cdat(parm1)) And (doc.creationDate(0) < CDat(parm2)) then ... end if but the results are off Included! Date:3/12/10 11:07:08 P1:3/1/10 P2: 3/5/10 Included! Date:3/13/10 9:15:09 P1:3/1/10 P2: 3/5/10 Included! Date:3/17/10 16:22:07P1:3/1/10 P2: 3/5/10 You can see that the date stored in the doc is not between P1 and P2. BUT! it does limit the documents with a date less than P1 correctly. So I won't get a result for a document with a date less than 3/1/10 If there isn't a better way than the if statement, can someone help me understand why the two examples from above are included?

  • confusing fork system call

    - by benjamin button
    Hi, i was just checking the behaviour of fork system call and i found it very confusing. i saw in a website that Unix will make an exact copy of the parent's address space and give it to the child. Therefore, the parent and child processes have separate address spaces #include <stdio.h> #include <sys/types.h> int main(void) { pid_t pid; char y='Y'; char *ptr; ptr=&y; pid = fork(); if (pid == 0) { y='Z'; printf(" *** Child process ***\n"); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); sleep(5); } else { sleep(5); printf("\n ***parent process ***\n",&y); printf(" Address is %p\n",ptr); printf(" char value is %c\n",y); } } the output of the above program is : *** Child process *** Address is 69002894 char value is Z ***parent process *** Address is 69002894 char value is Y so from the above mentioned statement it seems that child and parent have separet address spaces.this is the reason why char value is printed separately and why am i seeing the address of the variable as same in both child and parent processes.? Please help me understand this!

  • Grails , how do I get an object NOT to save

    - by user350325
    Hello I am new to grails and trying to create a form which allows a user to change the email address associated with his/her account for a site I am creating. It asks for the user for their current password and also for the new email address they want to use. If the user enters the wrong password or an invalid email address then it should reject them with an appropriate error message. Now the email validation can be done through constraints in grails, but the password change has to match their current password. I have implemented this check as a method on a service class. See code below: def saveEmail = { def client = ClientUser.get(session.clientUserID) client.email = params.email if(clientUserService.checkPassword(session.clientUserID , params.password) ==false) { flash.message = "Incorrect Password" client.discard() redirect(action:'changeEmail') } else if(!client.validate()) { flash.message = "Invalid Email Address" redirect(action:'changeEmail') } else { client.save(); session.clientUserID = null; flash.message = "Your email address has been changed, please login again" redirect(controller: 'clientLogin' , action:'index') } } Now what I noticed that was odd was that if I entered an invalid email then it would not save the changes (as expected) BUT if I entered the wrong password and a valid email then it would save the changes and even write them back into the database even though it would give the correct "invalid password" error message. I was puzzled so set break points in all the if/else if/else blocks and found that it was hitting the first if statement as expected and not hitting the others , so it would never come accross a call to the save() method, yet it was saved anyway. After a little research I came accross documentation for the discard() method which you can see used in the code above. So I added this but still no avail. I even tried using discard then reloading the client object from the DB again but still no dice. This is very frustrating and I would be grateful for any help, since I think that this should surely not be a complicated requirement!

  • Programming Concepts: What should be done when an exception is thrown?

    - by Dooms101
    This does not really apply to any language specifically, but if it matters I am using VB.NET in Visual Studio 2008. I can't seem to find anything really that useful using Google about this topic, but I was wondering what is common practice when an exception is thrown and caught but since it has been thrown the application cannot continue operating. For example I have exceptions that are thrown by my FileLoader class when a file cannot be found or when a file is deemed corrupt. The exception is only thrown within the class and is not handled really. If the error is detected, then the exception is thrown and whatever function is was thrown is basically quits. So in the code trying to create that object or call one of its members I use a Try...Catch statement. However, I was wondering, what should even do when this exception is caught? My application needs these files to be intact, and if they are not, the application is almost useless. So far I just pop up a message box telling the user their is an error and to reinstall. What else can I do, or better, what's common practice in these situations?

  • Assigning console.log to another object (Safari issue)

    - by Trevor Burnham
    I wanted to keep my logging statements as short as possible while preventing console from being accessed when it doesn't exist; I came up with the following solution: var _ = {}; if (console) { _.log = console.debug; } else { _.log = function() { } } To me, this seems quite elegant, and it works great in Firefox 3.6 (including preserving the line numbers that make console.debug more useful than console.log). But it doesn't work in Safari 4. (Haven't tested in other browsers yet.) If I follow the above with console.debug('A') _.log('B'); the first statement works fine in both browsers, but the second generates a "TypeError: Type Error" in Safari. Is this just a difference between how Firebug and the Safari Web Developer Tools implement console? If so, it is VERY annoying on Apple's part. (I get the same results in both browsers if I bind the console function to a prototype and then instantiate, rather than binding it directly to the object.) I could, of course, just call console.debug from an anonymous function assigned to _.log, but then I'd lose my line numbers. Any other ideas?

  • Passing NSArray Pointer Rather Than A Pointer To a Specific Type

    - by mattmccomb
    I've just written a piece of code to display a UIActionSheet within my app. Whilst looking at the code to initialise my UIActionSheet something struck me as a little strange. The initialisation function has the following signature... initWithTitle:(NSString *)title delegate:(id UIActionSheetDelegate)delegate cancelButtonTitle:(NSString *)cancelButtonTitle destructiveButtonTitle:(NSString *)destructiveButtonTitle otherButtonTitles:(NSString *)otherButtonTitles As you can see the otherButtonTitles parameter is a pointer to a String. In my code I set it as follows... otherButtonTitles: @"Title", @"Date", nil Although this compiles fine I don't really understand how it works. My reading of the statement is that I have created an inline array containing two elements (Title and Date). How come this then compiles? I'm passing a NSArray* in place of a NSString*. I know from a little of understanding of C++ that an array is really a pointer to the first element. So is this inline array that I'm creating a C array as opposed to a NSArray? What I'm hoping to achieve is to be able to pass a static NSArray* used elsewhere in my class to the otherButtonTitles parameter. But passing the NSArray* object directly doesn't work.

  • Access 2007 DAO VBA Error 3381 causes objects in calling methods to "break".

    - by MT
    ---AFTER FURTHER INVESTIGATION--- "tblABC" in the below example must be a linked table (to another Access database). If "tblABC" is in the same database as the code then the problem does not occur. Hi, We have recently upgraded to Office 2007. We have a method in which we have an open recordset (DAO). We then call another sub (UpdatingSub below) that executes SQL. This method has its own error handler. If error 3381 is encountered then the recordset in the calling method becomes "unset" and we get error 3420 'Object invalid or no longer set'. Other errors in UpdatingSub do not cause the same problem. This code works fine in Access 2003. Private Sub Whatonearth() Dim rs As dao.Recordset set rs = CurrentDb.OpenRecordset("tblLinkedABC") Debug.Print rs.RecordCount UpdatingSub "ALTER TABLE tblTest DROP Column ColumnNotThere" 'Error 3240 occurs on the below line even though err 3381 is trapped in the calling procedure 'This appears to be because error 3381 is encountered when calling UpdatingSub above Debug.Print rs.RecordCount End Sub Private Sub WhatonearthThatWorks() Dim rs As dao.Recordset set rs = CurrentDb.OpenRecordset("tblLinkedABC") Debug.Print rs.RecordCount 'Change the update to generate a different error UpdatingSub "NONSENSE SQL STATEMENT" 'Error is trapped in UpdatingSub. Next line works fine. Debug.Print rs.RecordCount End Sub Private Sub UpdatingSub(strSQL As String) On Error GoTo ErrHandler: CurrentDb.Execute strSQL ErrHandler: 'LogError' End Sub Any thoughts? We are running Office Access 2007 (12.0.6211.1000) SP1 MSO (12.0.6425.1000). Perhaps see if SP2 can be distributed? Sorry about formatting - not sure how to fix that.

  • Need help running Python app as service in Ubuntu with Upstart

    - by GreeenGuru
    I have written a logging application in Python that is meant to start at boot, but I've been unable to start the app with Ubuntu's Upstart init daemon. When run from the terminal with sudo /usr/local/greeenlog/main.pyw, the application works perfectly. Here is what I've tried for the Upstart job: /etc/init/greeenlog.conf # greeenlog description "I log stuff." start on startup stop on shutdown script exec /usr/local/greeenlog/main.pyw end script My application starts one child thread, in case that is important. I've tried the job with the expect fork stanza without any change in the results. I've also tried this with sudo and without the script statements (just a lone exec statement). In all cases, after boot, running status greeenlog returns greeenlog stop/waiting and running start greeenlog returns: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.61" (uid=1000 pid=2496 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) Can anyone see what I'm doing wrong?

  • Where Not In OR Except simulation of SQL in LINQ to Objects

    - by Thinking
    Suppose I have two lists that holds the list of source file names and destination file names respectively. The Sourcefilenamelist has files as 1.txt, 2.txt,3.txt, 4.txt while the Destinaitonlist has 1.txt,2.txt. I ned to write a linq query to find out which files are in SourceList that are absent in DestinationFile list. e.g. here the out put will be 3.txt and 4.txt. I have done this by a foreach statement. but now I want to do the same by using LINQ(C#). Edit: My Code is List<FileList> sourceFileNames = new List<FileList>(); sourceFileNames.Add(new FileList { fileNames = "1.txt" }); sourceFileNames.Add(new FileList { fileNames = "2.txt" }); sourceFileNames.Add(new FileList { fileNames = "3.txt" }); sourceFileNames.Add(new FileList { fileNames = "4.txt" }); List<FileList> destinationFileNames = new List<FileList>(); destinationFileNames.Add(new FileList { fileNames = "1.txt" }); destinationFileNames.Add(new FileList { fileNames = "2.txt" }); IEnumerable<FileList> except = sourceFileNames.Except(destinationFileNames); And Filelist is a simple class with only one property fileNames of type string.

  • PHP / Zend Framework: Force prepend table name to column name in result array?

    - by Brian Lacy
    I am using Zend_Db_Select currently to retrieve hierarchical data from several joined tables. I need to be able to convert this easily into an array. Short of using a switch statement and listing out all the columns individually in order to sort the data, my thought was that if I could get the table names auto-prepended to the keys in the result array, that would solve my problem. So considering the following (assembled) SQL: SELECT user.*, contact.* FROM user INNER JOIN contact ON contact.user_id = user.user_id I would normally get a result array like this: [username] => 'bob', [contact_id] => 5, [user_id] => 2, [firstname] => 'bob', [lastname] => 'larsen' But instead I want this: [user.user_id] => 2, [user.username] => 'bob', [contact.contact_id] => 5, [contact.firstname] => 'bob', [contact.lastname] => 'larsen' Does anyone have an idea how to achieve this? Thanks!

    I'm a newb when it comes to javascript. Perhaps somebody could help me with this. I assume it is not very complicated. This is what I would like: <SCRIPT type=text/javascript> var StandardURL = "http://site/Lists/test/AllItems.aspx"; </script> <SCRIPT type=text/javascript> var FilterURL = "http://site/Lists/test//AllItems.aspx?FilterField1=Judge&FilterValue1="; </script> var DynamicURL = FilterURL + DynamicUserInf (no space between it should be like one url link), dynamicuserinf contains different value depending on the user that is logged in no need to worry what is in it. It already contains a value befor this runs Get current URL in [var CurrentURL] <script language="JavaScript" type="text/javascript"> if (CurrentURL == StandardURL) { location.href= (DynamicURL);} </script> ElSE do nothing (i assume this is not neccarry with only one if statement) Hopefully not much of a mess.

  • Slow Python HTTP server on localhost

    - by Abiel
    I am experiencing some performance problems when creating a very simple Python HTTP server. The key issue is that performance is varying depending on which client I use to access it, where the server and all clients are being run on the local machine. For instance, a GET request issued from a Python script (urllib2.urlopen('http://localhost/').read()) takes just over a second to complete, which seems slow considering that the server is under no load. Running the GET request from Excel using MSXML2.ServerXMLHTTP also feels slow. However, requesting the data Google Chrome or from RCurl, the curl add-in for R, yields an essentially instantaneous response, which is what I would expect. Adding further to my confusion is that I do not experience any performance problems for any client when I am on my computer at work (the performance problems are on my home computer). Both systems run Python 2.6, although the work computer runs Windows XP instead of 7. Below is my very simple server example, which simply returns 'Hello world' for any get request. from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer class MyHandler(BaseHTTPRequestHandler): def do_GET(self): print("Just received a GET request") self.send_response(200) self.send_header("Content-type", "text/html") self.end_headers() self.wfile.write('Hello world') return def log_request(self, code=None, size=None): print('Request') def log_message(self, format, *args): print('Message') if __name__ == "__main__": try: server = HTTPServer(('localhost', 80), MyHandler) print('Started http server') server.serve_forever() except KeyboardInterrupt: print('^C received, shutting down server') server.socket.close() Note that in MyHandler I override the log_request() and log_message() functions. The reason is that I read that a fully-qualified domain name lookup performed by one of these functions might be a reason for a slow server. Unfortunately setting them to just print a static message did not solve my problem. Also, notice that I have put in a print() statement as the first line of the do_GET() routine in MyHandler. The slowness occurs prior to this message being printed, meaning that none of the stuff that comes after it is causing a delay.

  • PDCurses TUI with C++ Win32 console application

    - by Bach
    I have downloaded pdcurses source and was able to successfully include curses.h in my project, linked the pre-compiled library and all good. After few hours of trying out the library, I saw the tuidemo.c in the demos folder, compiled it into an executable and brilliant! exactly what I needed for my project. Now the problem is that it's a C code, and I am working on a C++ project in VS c++ 2008. The files I need are tui.c and tui.h How can I include that C file in my C++ code? I saw few suggestions here but the compiler was not too happy with 100's of warnings and errors. How can I go on including/using that TUI pdcurses includes!? Thanks EDIT: I added extern "C" statement, so my test looks like this now, but I'm getting some other type of error #include <stdio.h> #include <stdlib.h> using namespace std; extern "C" { #include <tui.h> } void sub0(void) { //do nothing } void sub1(void) { //do nothing } int main (int argc, char * const argv[]) { menu MainMenu[] = { { "Asub", sub0, "Go inside first submenu" }, { "Bsub", sub1, "Go inside second submenu" }, { "", (FUNC)0, "" } /* always add this as the last item! */ }; startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); return 0; } Although it is compiling successfully, it is throwing an Error at runtime: 0xC0000005: Access violation reading location 0x021c52f9 at line startmenu(MainMenu, "TUI - 'textual user interface' demonstration program"); Not sure where to go from here. thanks again.

  • Advantage Database Server ORDER BY behaviour

    - by ie
    I'm using ADS v10 beta. I'm trying to numerate ordered resultset. 1) ORDER BY in nested queries. I need to use nested SELECT for some calculations: SELECT Name, Value, ROWNUM() FROM (SELECT * FROM MainTable WHERE Value > 0 ORDER BY Value) a And I'm getting Expected lexical element not found: ) There was a problem parsing the table names after the FROM keyword in your SELECT statement. Everything is working well when the ORDER BY is removed. Although, I found the sample in the Help, it looks like my query (more complex, indeed): SELECT * FROM (SELECT TOP 10 empid, fullname FROM branch1 ORDER BY empid) a UNION SELECT empid, fullname FROM branch2 ORDER BY empid 2) ORDER BY + ROWNUM(). I used the nested query in the example above, to numerate ordered rows. Is there are any chance to avoid nested query? In the SQL Server I can do something like this: SELECT Name, Value, ROW_NUMBER() OVER(ORDER BY Value) FROM MainTable WHERE Value > 1 ORDER BY Value Please advice. Thanks.

  • Windows SQL wildcards and ASP.net parameters

    - by Vinzcent
    Hey In my SQL statement I use wildcards. But when I try to select something, it never select something. While when I execute the querry in Microsoft SQL Studio, it works fine. What am I doing wrong? Click handler protected void btnTitelAuteur_Click(object sender, EventArgs e) { cvalTitelAuteur.Enabled = true; cvalTitelAuteur.Validate(); if (Page.IsValid) { objdsSelectedBooks.SelectMethod = "getBooksByTitleAuthor"; objdsSelectedBooks.SelectParameters.Clear(); objdsSelectedBooks.SelectParameters.Add(new Parameter("title", DbType.String)); objdsSelectedBooks.SelectParameters.Add(new Parameter("author", DbType.String)); objdsSelectedBooks.Select(); gvSelectedBooks.DataBind(); pnlZoeken.Visible = false; pnlKiezen.Visible = true; } } In my Data Acces Layer public static DataTable getBooksByTitleAuthor(string title, string author) { string sql = "SELECT 'AUTHOR' = tblAuthors.FIRSTNAME + ' ' + tblAuthors.LASTNAME, tblBooks.*, tblGenres.GENRE " + "FROM tblAuthors INNER JOIN tblBooks ON tblAuthors.AUTHOR_ID = tblBooks.AUTHOR_ID INNER JOIN tblGenres ON tblBooks.GENRE_ID = tblGenres.GENRE_ID " +"WHERE (tblBooks.TITLE LIKE '%@title%');"; SqlDataAdapter da = new SqlDataAdapter(sql, GetConnectionString()); da.SelectCommand.Parameters.Add("@title", SqlDbType.Text); da.SelectCommand.Parameters["@title"].Value = title; DataSet ds = new DataSet(); da.Fill(ds, "Books"); return ds.Tables["Books"]; } Thanks, Vincent
