  • Why does my app crash when I add an row to the table view?

    - by mystify
    I'm adding a row like this, when a button is pressed. It must be the very first row in the first section: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; I don't call anything else here. No -reloadData. I keep getting this: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (6) must be equal to the number of rows contained in that section before the update (6), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).'

    - by atricapilla
    I have many .sql files with lots of empty lines e.g. WITH cteTotalSales (SalesPersonID, NetSales) AS ( SELECT SalesPersonID, ROUND(SUM(SubTotal), 2) FROM Sales.SalesOrderHeader WHERE SalesPersonID IS NOT NULL GROUP BY SalesPersonID ) SELECT sp.FirstName + ' ' + sp.LastName AS FullName, sp.City + ', ' + StateProvinceName AS Location, ts.NetSales FROM Sales.vSalesPerson AS sp INNER JOIN cteTotalSales AS ts ON sp.BusinessEntityID = ts.SalesPersonID ORDER BY ts.NetSales DESC Is ther a way to remove these empty lines in SQL Server Management Studio?

  • How to delete just one LINE of text (NOT a table-row!) with a single KEYBOARD shortcut in Microsoft Office Word 2010?

    - by Sk8erPeter
    Are there any shortcuts to delete just one row (which is NOT a table row, just a single row in a text) in Microsoft Office Word 2010? If not, how can I assign one to do it? In worst case, can I make a macro (in VB) which could do the same with a custom shortcut? To clarify my problem: I would like to avoid multiple clicks and/or pushing multiple buttons, even if I click in the middle of the line of text. :) For example, in Notepad++ I can delete the entire current line with Ctrl+L, in NetBeans, I can delete an entire line with Ctrl+E, in Eclipse, I can delete current line with Ctrl+D, etc., where it doesn't really matter where my mouse cursor is actually... so there are these simple solutions, which I look for in Word too. It really would simplify my work in huge documents.

  • Internet Explorer background-color hover problem

    - by danilo
    I have a strange Problem with table formating using IE 7. My table looks like this: In IE, when using border-collapse, the borders don't get displayed correctly. That's why I used this fix: .table-vmlist td { border-top: 1px solid black; } td.col-vm-status, tr.row-details td { border-left: 1px solid black; } td.col-vm-rdp, tr.row-details td { border-right: 1px solid black; } .table-vmlist { border-bottom: 1px solid black;} When hovering over the row, it gets highlighted with CSS: .table-vmlist tr.row-vm { background-color: #A4C3EF; } .table-vmlist tr.row-vm:hover { background-color: #91BAEF; } Now, in IE 7, when moving the mouse from the top to the bottom of the list, every row gets highlighted correctly and no problems happen. But if I move my mouse pointer from the bottom of the list to the top, every second row seems to loose the border. Can someone explain what the problem is, and how to solve it? This is my markup: <tr class="row-vm"> <td class="col-vm-status status-1"><img title="Host Down" alt="Down" src="/Technik/vm-management/img/hoststatus_1.png"></td> <td class="col-vm-name">V1-VM-1</td> <td class="col-vm-stati"> <img title="Ping" alt="Ping status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="CPU" alt="CPU status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="RAM" alt="RAM status" src="/Technik/vm-management/img/servicestatus_3.png"> <img title="C:\ Diskspace" alt="Disk space status" src="/Technik/vm-management/img/servicestatus_3.png"> </td> <td class="col-vm-owner">kus</td> <td class="col-vm-purpose">Citrix Testserver</td> <td class="col-vm-ip">-</td> <td class="col-vm-uptime">-</td> <td class="col-vm-rdp">&nbsp;</td> </tr> And the CSS: /* VM-Tabelle formatieren */ .table-vmlist { border-collapse: collapse; } .table-vmlist tr { border: 1px solid black; } .table-vmlist tr.row-header { border: none; } .table-vmlist tr.row-vm { background-color: #A4C3EF; } .table-vmlist tr.row-vm:hover { background-color: #91BAEF; } .table-vmlist th { text-align: left; } .table-vmlist td { } .table-vmlist th, table td { padding: 2px 0px; } /* Spaltenbreite der VM-Tabelle festlegen */ .table-vmlist #col-status { width: 25px; } .table-vmlist #col-stati { width: 90px; } .table-vmlist #col-owner { width: 90px; } .table-vmlist #col-ip { width: 100px; } .table-vmlist #col-uptime { width: 70px; } .table-vmlist #col-rdp { width: 25px; } .table-vmlist tr.row-details td { padding: 0px 10px; } /* Kein Rahmen um verlinkte Bilder */ a img { border-width: 0px; } /* Für Einschaltknopf Hand-Cursor anstatt normalen Pfeil anzeigen */ td.status-1 img { cursor: pointer; } img.ajax-loader { margin-left: 2px; } IE fix: .table-vmlist td { border-top: 1px solid black; } td.col-vm-status, tr.row-details td { border-left: 1px solid black; } td.col-vm-rdp, tr.row-details td { border-right: 1px solid black; } .table-vmlist { border-bottom: 1px solid black;}

  • Antlr MismatchedSetException During Interpretation

    - by user1646481
    I am new to Antlr and I have defined a basic grammar using Antlr 3. The grammar compiles and ANTLRWorks generates the Parser and Lexer code without any problems. The grammar can be seen below: grammar i; @header { package i; } module : 'Module1'| 'Module2'; object : 'I'; objectType : 'Name'; filters : EMPTY | 'WHERE' module; table : module object objectType; STRING : ('a'..'z'|'A'..'Z')+; EMPTY : ' '; The problem is that when I interpret the table Parser I get a MismatchedSetException. This is due to having the EMPTY. As soon as I remove EMPTY from the grammar, the interpretation works. I have looked on the Antlr website and some other examples and the Empty space is ' '. I am not sure what to do. I need this EMPTY. As soon as I change the EMPTY to be the following: EMPTY : ''; instead of: EMPTY : ' '; It actually interprets it. However, I am getting the following Exception: Interpreting... [10:57:23] problem matching token at 1:4 NoViableAltException(' '@[1:1: Tokens : ( T__4 | T__5 | T__6 | T__7 | T__8 | T__9 | T__10 | T__11 | T__12 | T__13 | T__14 | T__15 | T__16 );]) [10:57:23] problem matching token at 1:9 NoViableAltException(' '@[1:1: Tokens : ( T__4 | T__5 | T__6 | T__7 | T__8 | T__9 | T__10 | T__11 | T__12 | T__13 | T__14 | T__15 | T__16 );]) When I take out the EMPTY, there are no problems at all. I hope you can help.

  • Empty Recycle Bin error "Cannot Delete Dc12: Access denied."

    - by Chris Noe
    The Dc number can vary. The error is a sporadic, but when it happens it prevents the contents of the recycle bin from being deleted. It can also occur when the recycle bin appears to be empty, yet it has the crumpled paper indicator. Rebooting makes the problem go away, but it can also magically go away by just waiting a long time, like over night. But the problem keeps recurring with no rhyme or reason. What is causing this? I really don't want to reinstall Windows.

  • Compact matlab matrix indexing notation

    - by AnnaR
    I've got an nxk sized matrix, containing k numbers per row. I want to use these k number as indexes to k-dimensional matrix. Is there any compact way of doing so in matlab or must I use a for-loop? This is what I want to do (in matlab-pseudo code), but in a more matlabish way. for row=1:1:n finalTable(row) = kDimensionalMatrix(indexmatrix(row, 1),... indexmatrix(row, 2),...,indexmatrix(row, k)) end

  • Using an empty keystore password used to be possible?

    - by TomTasche
    When signing an apk after a long break from Android development I was surprised that I'm no longer able to enter an empty keystore password to unlock it. Is it just me or has this been possible before? If so, when did that change and how can I manage to unlock the keystore anyway? Some background: maybe I'm just crazy and didn't use an empty password for the keystore before, but the one and only possible password that I could have been using instead doesn't work either (I swear, there's no chance I'd have used another password!).

  • What is the default value for Empty Temporary Internet Files when browser is closed in IE8?

    - by schellack
    We have four different machines that all have "Empty Temporary Internet Files when browser is closed" set to true (checked) in IE8's Internet Options (located under the Security section in the Advanced tab). No one remembers checking that checkbox to turn on the setting. What is the default value supposed to be? I'm specifically interested in Windows 7 and Windows XP. I have run rsop.msc on one of the corporate machines—3 of the 4 are members of a corporate network/domain—and see this under User Configuration, which makes the current scenario seem even stranger: The Local Group Policy Editor (gpedit.msc) also shows the Configure Delete Browsing History on exit setting to be Not configured (under Computer ConfigurationAdministrative TemplatesWindows ComponentsInternet ExplorerDelete Browsing History).

  • Why does my excel document have 960,000 empty rows?

    - by C-dizzle
    I have an excel document, Office 2007, on a Windows 7 machine (if that part matters any, I'm not sure but just throwing it out there). It is a list of all employee phone numbers. If I need to generate a new page, I can click on page 2 and the table will automatically generate again. The problem is, someone messed it up since it's on a network drive and now shows I have over 960,000 rows of data, when I really don't! I did CTRL+END to see if any data was in the last cell, so I cleared it out, deleted that row and column, but still didn't fix it. It almost seems like it duplicates itself after the deletion. How can I fix this instead of recreating the entire document?

  • How to get null when use head funtion with a empty list in cypher?

    - by PeaceMaker
    I have a cypher query like this. START dep=node:cities(city_code = "JGS"), arr=node:cities(city_code = "XMN") MATCH dep-[way:BRANCH2BRANCH_AIRWAY*0..1]->()-->arr RETURN length(way), transfer.city_code, extract(w in way: w.min_consume_time) AS consumeTime The relationship named "way" is a optional one, so the property named "consumeTime" will be a empty list when the relationship "way" not exsit. The query result is: | 0 | "JGS" | [] | | 1 | "SZX" | [3600] | When I want to use the head function with the property "consumeTime", it return a error "Invalid query: head of empty list".

  • Why the vertical scroll bar moves automatically ?

  • Listing issue, GROUP mysql

    - by SethCodes
    Here is a mock-up example of Mysql table: | ID | Country | City | ________________________________ | 1 | Sweden | Stockholm | | 2 | Sweden | Stockholm | | 3 | Sweden | Lund | | 4 | Sweden | Lund | | 5 | Germany | Berlin | | 6 | Germany | Berlin | | 7 | Germany | Hamburg | | 8 | Germany | Hamburg | Notice how both rows Country and city have repeated values inside them. Using GROUP BY country, city in my PDO query, the values will not repeat while in loop. Here is PDO for this: $query = "SELECT id, city, country FROM table GROUP BY country, city"; $stmt = $db->query($query); while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : The above code will result in an output like this (some editing in-between). GROUP BY works but the country repeats: Sweden - Stockholm Sweden - Lund Germany - Berlin Germany - Hamburg Using bootstrap collapse and above code, I separate the country from the city with a simple drop down collopase. Here is code: <li> <a data-toggle="collapse" data-target="#<?= $row['id']; ?>" href="search.php?country=<?= $row['country']; ?>"> <?= $row['country']; ?> </a> <div id ="<?= $row['id']; ?>" class="collapse in"> //collapse div here <a href="search.php?city=<?= $row['city']; ?>"> <?= $row['city']; ?><br></a> </div> //end </li> It then looks something like this (once collapse is initiated): Sweden > Stockholm Sweden > Lund Germany >Berlin Germany >Hamburg Here is where I face the problem. The above lists the values Sweden and Germany 2 times. I want Sweden and Germany to only list one time, and the cities listed below, so the desired look is to be this: Sweden // Lists one time > Stockholm > Lund Germany // Lists one time >Berlin >Hamburg I have tried using DISTINCT, GROUP_CONTACT and other methods, yet none get my desired output (above). Suggestions? Below is my current full code in action: <? $query = "SELECT id, city, country FROM table GROUP BY country, city"; $stmt = $db->query($query); while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : ?> <li> <a data-toggle="collapse" data-target="#<?= $row['id']; ?>" href="search.php?country=<?= $row['country']; ?>"> <?= $row['country']; ?> </a> <div id ="<?= $row['id']; ?>" class="collapse in"> //collapse div here <a href="search.php?city=<?= $row['city']; ?>"> <?= $row['city']; ?><br></a> </div> //end </li> <? endwhile ?>

  • Would this prevent the row from being read during the transaction?

    - by acidzombie24
    I remember an example where reads in a transaction then writing back the data is not safe because another transaction may read/write to it in the time between. So i would like to check the date and prevent the row from being modified or read until my transaction is finish. Would this do the trick? and are there any sql variants that this will not work on? update tbl set id=id where date>expire_date and id=@id Note: dateexpire_date happens to be my condition. It could be anything. Would this prevent other transaction from reading the row until i commit or rollback?
