  • Help with editing data in entity framework.

    - by Levelbit
    Title of this question is simple because there is no an easy explanation for what I'm trying to ask you. I hope you'll understand in the end :). I have to tables in my database: Company and Location (relationship:one to many) and corresponding entity sets. In my wpf application I have some datagrid which I want to fill with locations and to be able to edit every row in separate window as some form of details view (so I don't want to edit my data in datagrid). I did this by accessing Location entity from selected row and creating a new Location entity and then I copy properties from original entity to newly created. Something like cloning the object. After editing if I press OK changed data is copied to original object back, and if I press Cancel nothing happens. Of course, you probably thinking I could use NoTracking option and AttachAsModified method as was mentioned as solution in some earlier questions(see:http://stackoverflow.com/questions/803022/changing-entities-in-the-entityframework) by Alex James, but lets say I had some problems about that and I have my own reasons for doing this. Finally, because navigation property(Company) of my location entity is assigned to newly created location object(during cloning) from some reason in object context additional object as copy of object I want to edit from datagrid is created without my will(similar problem :http://blogs.msdn.com/alexj/archive/2009/12/02/tip-47-how-fix-up-can-make-it-hard-to-change-relationships.aspx). So, when I do ObjectContext.SaveChanges it inserts additional row of data into my database table Location, the same as the one i wanted to edit. I read about sth like this, but I don't quite understand why is that and how to block or override this. I hope I was clear as I could. Please, solutions or some other ideas.

  • Push different views from a table.

    - by Tanner
    Hello All, Ive been following a tutorial to implement a search bar ( http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html ) However I cant seem to push different views. Here is what my didsSelectRowAtIndexPath looks like. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *selectedCountry = nil; if(searching) selectedCountry = [copyListOfItems objectAtIndex:indexPath.row]; else { NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section]; NSArray *array = [dictionary objectForKey:@"Countries"]; selectedCountry = [array objectAtIndex:indexPath.row]; } //Initialize the detail view controller and display it. if ([[listOfItems objectAtIndex:indexPath.row] isEqual:@"neon"]){ Neon *abo = [[Neon alloc] initWithNibName:@"Neon" bundle:nil]; //dvController.selectedCountry = selectedCountry; [self.navigationController pushViewController:abo animated:YES]; [abo release]; } } And here is the debuger message when I click on neon: 2010-05-09 08:47:27.516 iTeachU[3821:307] * Terminating app due to uncaught exception 'NSRangeException', reason: ' -[NSMutableArray objectAtIndex:]: index 60 beyond bounds [0 .. 0]' ** Call stack at first throw: terminate called after throwing an instance of 'NSException' Program received signal: “SIGABRT”. If anyone has a way to push views based on the cells text it would be greatly appreciated. Thanks

  • java recursion on array

    - by user69514
    I have to create a program that finds all the possible ways of filling a board of size 3xN You place a domino which takes up 2 spaces to completely fill the board. So far, this is my thought process on how it should be done based on what the teacher has said as well as my own thoughts. Get input and check if its even or odd If it's odd, the board can't be filled all the way and the program ends If it's even, place a domino horizontally in the top right corner of the board Test if you can place a domino vertically in that spot. Repeat those two steps as many times as possible. The problem is I don't know how to code it to the point where you can remember the placements of each domino. I can get it to where it fills the board completely once and maybe twice, but nothing past that. I also know that I'm supposed to use recursion to figure this out fwiw. Here is the code I started on so far. There is also a main method and I have the initial even/odd check working fine. This is the part I have no idea on. public void recurDomino(int row, int column) { if (Board[2][x - 1] != false) { } else if(Board[1][x-1]!=false) { } else { for (int n=0; n < x - 1; n++) { Board[row][column] = true; Board[row][column+1] = true; column++; counter++; } recurDomino(1, 0); recurDomino(2, 0); } } Thank you for any help you guys can give me.

  • Changing Positions of the Chart When Creating Multiple Charts Automatically via Vbasic in Excel 2007

    - by McVey
    I am creating a new chart for each row of data in an Excel spreadsheet. I have the Vbasic working properly, but I want to change the position of the chart on the sheet that is added for each row. Below is my code, what do I need to do to change the position of the chart on the page automatically? Ideally, I would like it to be in the upper left hand corner of each sheet. Sub DrawCharts() Dim Ws As Worksheet Dim NewWs As Worksheet Dim cht As Chart Dim LastRow As Long Dim CurrRow As Long Set Ws = ThisWorkbook.Worksheets("Sheet1") LastRow = Ws.Range("A65536").End(xlUp).Row For CurrRow = 2 To LastRow Set NewWs = ThisWorkbook.Worksheets.Add NewWs.Name = Ws.Range("A" & CurrRow).Value Set cht = ThisWorkbook.Charts.Add With cht .ChartType = xl3DColumnClustered .SeriesCollection.NewSeries .SeriesCollection(1).Values = "=" & Ws.Name & "!R" & CurrRow & "C3:R" & CurrRow & "C8" .SeriesCollection(1).Name = "=" & Ws.Name & "!R" & CurrRow & "C2" .SeriesCollection(1).XValues = "Sheet1!R1C3:R1C8" .Axes(xlValue).MinimumScale = 0 .Axes(xlValue).MaximumScale = 1 .Axes(xlValue).MajorUnit = 0.2 .SetElement (msoElementDataLabelShow) .SetElement (msoElementLegendNone) .Location Where:=xlLocationAsObject, Name:=NewWs.Name End With Next CurrRow End Sub Any help is appreciated.

  • Simple grid layout question

    - by Matt H.
    I can't believe I'm back to this after working with WPF for 3 months :) Consider very common setup: How do I configure the rowheights so that the top and bottom rows (menu bar and status bar) size to fit the height of their content, and the middle row (main content), fills the remaining available space in the program? I can't fix the height of the top/bottom rows because the height of their content can vary. <Window> <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Menu Grid.Row=0> ...menuitems </Menu> <Grid Grid.Row=1> ...main application content here (like most programs) </Grid> <StatusBar> ...statusbaritems </StatusBar> </Grid> </Window>

  • question about InnoDB deadlock in MySQL?

    - by WilliamLou
    I found this kind of interesting problem in MySQL InnoDB engine, could anyone explain why the engine always claim it's a deadlock. First, I created a table with a single row, single column: CREATE TABLE `SeqNum` (`current_seq_num` bigint(30) NOT NULL default '0', PRIMARY KEY (`current_seq_num`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 | Now, I have two MySQL connector threads, In thread1: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; Query OK, 1 row affected (0.00 sec) Now, in thread2, I did the exactly same: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; before the default innodb_lock_wait_timeout, the thread2 just wait for thread1 to release its exclusive lock on the table, and it's normal. However, in thread1, if I input the following update query: mysql> update SeqNum set `current_seq_num` = 8; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction Now, thread2 get the select query finished because thread1 quits. In addition, in thread1, if I input the update query with a where clause, it can be executed very well: mysql> update SeqNum set `current_seq_num` = 8 where `current_seq_num` =5 Query OK, 1 row affected (0.00 sec) Could anyone explain this?

  • JQGRID Master detail on different pages

    - by dennisg
    Hello, I need some help on next things. I was trying to do next few things. I have one grid_test.php (that creates jqgrid) and index_grid.php (just to display grid.php). jQGrid in grid.php have custom button named 'Prikazi'. I want the user to select one row from that grid and when press custom button 'Prikazi' to redirect to another page to show subgrid (and to pass parameter which is the id of the selected row). Subgrid is in the file detail_test.php and also I have file called index_detail.php (for displaying the file detail_test.php with jqgrid). These php files communicate by passing parameter id_reda (or id) that is id of the selected row in grid_test.php. I have tried many ways to achieve that but I wasn't able. Subgrid php file (detail_test.php) receives that parameter but when I add that to sql statement in subgrid file it shows next error: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 0, 0' at line 16' in C:\Zend\Apache2\htdocs\jqSuitePHP3811SourceRadna\php\jqGridPdo.php:62 I really don't know what am I doing wrong. Maybe the passing of parameter is wrong and maybe subgrid can't create colModel properly. Or it has something to do with sql statements. Actually my work was based on one of your examples masterdetail, but I wanted to have master grid on one page and when user clicks custom button, goes to another page with detail grid. You can see my example on next page: http://pljevlja.org/grid/index_test.php. And all my php files are here: -http://pljevlja.org/grid/TXT.zip<- Thanks in advance,

  • Apache POI Comment Excel

    - by Marquinio
    I need to add a comment to an HSSF Cell in Excel. Everything works fine the very first time but if I open the same file and run the code again it corrupts the file. I've also noticed that I need to create a Drawing object on a Sheet only once: _sheet.createDrawingPatriarch(); If the line above gets executed more than once comments will not work. So has anyone tried adding comments to Cells, closing the file, opening the file again and trying to add more comments to different cells? The below code works but if I open the file again then comments are not added, plus the file gets corrupted!!! Is there a way to get the existing Drawing object from a Sheet? Any ideas appreciated. Thanks!! _drawing = (HSSFPatriarch) _sheet.createDrawingPatriarch(); Row row = _sheet.getRow(rowIndex_); Cell cell = row.getCell(0); CreationHelper factory = _workbook.getCreationHelper(); HSSFAnchor anchor = new HSSFClientAnchor(0, 0, 0, 0, (short)4, 2, (short)6, 5); org.apache.poi.ss.usermodel.Comment comment = _drawing.createComment(anchor); RichTextString str = factory.createRichTextString("Hello, World "+rowIndex_); comment.setString(str); cell.setCellComment(comment);

  • How to update QStandartItemModel without freezing the main UI

    - by user1044002
    I'm starting to learn PyQt4 and have been stuck on something for a long time now and can't figure it out myself: Here is the concept: There is a TreeView with custom QStandartItemModel, which gets rebuild every couple of seconds, and can have a lot (hundreds at least) of entries, there also will be additional delegates for the different columns etc. It's fairly complex and the building time for even plain model, without delegates, goes up to .3 sec, which makes the TreeView to freeze. Please advice me for the best approach on solving this. I was thing of somehow building the model in different thread, and eventually sending it to the TreeView, where it would just perform setModel() with the new one, but couldn't make that work. here is some code that may illustrate the problem a bit: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys, os, re, time app = QApplication(sys.argv) REFRESH = 1 class Reloader_Thread(QThread): def __init__(self, parent = None): QThread.__init__(self, parent) self.loaders = ['\\', '--', '|', '/', '--'] self.emit(SIGNAL('refresh')) def run(self): format = '|%d/%b/%Y %H:%M:%S| ' while True: self.emit(SIGNAL('refresh')) self.sleep(REFRESH) class Model(QStandardItemModel): def __init__(self, viewer=None): QStandardItemModel.__init__(self,None) self.build() def build(self): stTime = time.clock() newRows = [] for r in range(1000): row = [] for c in range(12): item = QStandardItem('%s %02d%02d' % (time.strftime('%H"%M\'%S'), r,c)) row.append(item) newRows.append(row) eTime = time.clock() - stTime outStr = 'Build %03f' % eTime format = '|%d/%b/%Y %H:%M:%S| ' stTime = time.clock() self.beginRemoveRows(QModelIndex(), 0, self.rowCount()) self.removeRows(0, self.rowCount()) self.endRemoveRows() eTime = time.clock() - stTime outStr += ', Remove %03f' % eTime stTime = time.clock() numNew = len(newRows) for r in range(numNew): self.appendRow(newRows[r]) eTime = time.clock() - stTime outStr += ', Set %03f' % eTime self.emit(SIGNAL('status'), outStr) self.reset() w = QWidget() w.setGeometry(200,200,800,600) hb = QVBoxLayout(w) tv = QTreeView() tvm = Model(tv) tv.setModel(tvm) sb = QStatusBar() reloader = Reloader_Thread() tvm.connect(tvm, SIGNAL('status'), sb.showMessage) reloader.connect(reloader, SIGNAL('refresh'), tvm.build) reloader.start() hb.addWidget(tv) hb.addWidget(sb) w.show() app.setStyle('plastique') app.processEvents(QEventLoop.AllEvents) app.aboutToQuit.connect(reloader.quit) app.exec_()

  • WPF ComboBox binding

    - by Budda
    Here is peace of the XAML code from my page: <ComboBox Grid.Row="2" Grid.Column="1" Name="Player2" MinWidth="50" ItemsSource="{Binding PlayersTest}" DisplayMemberPath="ShortName"> custom object is binded to the page data context: page.DataContext = new SquadViewModel(); Here is part the source code of 'SquadViewModel' class: public class SquadViewModel { public SquadViewModel() { PlayersTest = new ObservableCollection<SostavPlayerData>(); PlayersTest.Add(new SostavPlayerData { ShortName = "A. Sereda", }); PlayersTest.Add(new SostavPlayerData { ShortName = "D. Sereda", }); } public readonly ObservableCollection<SostavPlayerData> PlayersTest; public string TestText { get { return "Binding works perfectly!"; } } } As a result ComboBox should display a list of objects, but it is empty. Do you know why and how to get this list? Thank you. P.S. I've tried another XAML markup <ComboBox Grid.Row="1" Grid.Column="1" Name="Player1" MinWidth="50" ItemsSource="{Binding PlayersTest}"> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding ShortName}"/> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> It doesn't work also, but binding to simple text block: <TextBlock Grid.Row="2" Grid.Column="1" Text="{Binding TestText}"/> Works perfectly.

  • PHP Variable with Array

    - by Crays
    Hi guys, i'm trying to make a "update user's power" page. It is something similar to those you can find in say, invisionfree forums. I need it to generate a list of members with checkbox [done] Add an option for it [done] What i don't know how to do is to update, to say, give all the selected users the selected power. Then i went searching for something and found most of them uses array to do this, but i never found one that actually explains how it works. The example i took (with my own modification) was this: while($row = mysql_fetch_array($result)) { echo '<tr>'.$id[]=$rows['id'].''; echo '<td width="50px" align="center" class="TableFormCell"><input type="checkbox" name="option[]" /></td>'; echo '<td width="170px" align="center" class="TableFormCell">'.$row['uname'].'</td>'; echo '</tr>'; } I'm not sure what exactly $id[]=$rows['id'] does I know after the row, my option[] would become an array of option[1], option[2], option[3] for what power should be given, i've got no problem with that but on how to update the database i'm got no clue... for($i=0;$i<$count;$i++){ $sql1="UPDATE ninos SET power='$power' WHERE id='$option[$i]'"; $result1=mysql_query($sql1); } So Say i have 5 users, Aye, Bee, Cee, Dee, Eee with IDs of 1,2,3,4,5 how can i make it so that my script would run like $sql1="UPDATE ninos SET power = '$power' Where id='1','2','3','4','5'"; Please help, thanks.

  • Why do I have to unserialize this serialized value twice?

    - by 55skidoo
    What am I doing wrong here? I'm serializing a value, storing it in a database (table bb_meta), retrieving it... OK so far... but then I have to unserialize it twice.

  • NSTableView Drag and Drop not working

    - by macatomy
    Hi, I'm trying to set up very basic drag and drop for my NSTableView. The table view has a single column (with a custom cell). The column is bound to an NSArrayController, and the array controller's content array is bound to an NSArray on my controller object. The data displays fine in the table. I connected the dataSource and delegate outlets of the table view to my controller object, and then implemented these methods: - (BOOL)tableView:(NSTableView *)aTableView writeRowsWithIndexes:(NSIndexSet *)rowIndexes toPasteboard:(NSPasteboard *)pboard { NSLog(@"dragging"); return YES; } - (NSDragOperation)tableView:(NSTableView*)tv validateDrop:(id <NSDraggingInfo>)info proposedRow:(NSInteger)row proposedDropOperation:(NSTableViewDropOperation)op { return NSDragOperationEvery; } - (BOOL)tableView:(NSTableView *)aTableView acceptDrop:(id <NSDraggingInfo>)info row:(NSInteger)row dropOperation:(NSTableViewDropOperation)operation { return YES; } I also registered the drag types in -awakeFromNib: #define MyDragType @"MyDragType" - (void)awakeFromNib { [super awakeFromNib]; [_myTable registerForDraggedTypes:[NSArray arrayWithObjects:MyDragType, nil]]; } The problem is that the -tableView:writeRowsWithIndexes:toPasteboard: method is never called. I've looked at a bunch of examples and I can't figure out anything I'm doing wrong. Could the problem be that I'm using a custom cell? Is there something I'm supposed to override in the cell subclass to enable this functionality? EDIT: Confirmed. Switching the custom cell for a regular NSTextFieldCell made dragging work. Now, how do I make drag and drop work with my custom cell?

  • Script working with mysql and php into a textarea and back

    - by Tribalcomm
    I am trying to write a custom script that will keep a list of strings in a textarea. Each line of the textarea will be a row from a table. The problem I have is how to work the script to allow for adding, updating, or deleting rows based on a submit. So, for instance, I currently have 3 rows in the database: john sue mark I want to be able to delete sue and add richard and it will delete the row with sue and insert a row for richard. My code so far is as follows: To query the db and list it in the textarea: $basearray = mysql_query("SELECT name FROM mytable ORDER BY name"); <textarea name="names" cols=6 rows=12>'); <?php foreach($basearray as $base){ echo $base->name."\n"; } ?> </textarea> After the submit, I have: <?php $namelist = $_REQUEST[names]; $newarray = explode("\n", $namelist); foreach($newarray as $name) { if (!in_array($name, $basearray)) { mysql_query(DELETE FROM mytable WHERE word='$name'"); } elseif (in_array($name, $basearray)) { ; } else { mysql_query("INSERT INTO mytable (name) VALUES ("$name")"); } } ?> Please tell me what I am doing wrong. I am not getting any functions to work when I edit the contents of the textarea. Thanks!

  • Reading a CSV with file_get_contents in PHP

    I am reading a 'kind' of csv file and exploding it and storing it in array. The file I am reading has this structure Id,Log,Res,File mydb('Test1','log1','Pass','lo1.txt'). mydb('Test2','log2','Pass','lo2.txt'). mydb('Test3','log3','Pass','lo3.txt'). Now what I am trying to do is : reading the last record in my database, get the Name, lets say in this case 'Test1' and then I am searching through my file and where I can find the position of 'Test1' and get the next lines in the file, extract the ID,s and add it to database. I am getting the position of desired string in the file, but I am not sure how to get the next lines too. Here's my code so far. <?php mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("testing") or die(mysql_error()); $result = mysql_query("select ID from table_1 order by S_no DESC limit 1") or die(mysql_error()); $row = mysql_fetch_array( $result ); $a = $row['ID']; echo 'Present Top Row is '.$a.'<br>'; $addresses = explode("\n", file_get_contents('\\\\fil1\\logs\\tes.pl')); foreach($addresses as $val) { $pos = strstr($val, $a); if ($pos === false) { } else { echo "The string <br> '$a' <br>was found in the string <br>'$val' <br>"; echo " and exists at position <br>$pos<br>"; } }

  • HELP with XML to XML transformation using XSLT.

    - by kaniths
    Am a rookie trying XSLT and XML tranformations for the first time. To start off, i tried a simple sample programs. I expected the Output in Tree format (maintaining the hierarchy) instead i just get " KING" in single line... What could be the problem? PS: I use XMLSpy. Any guideline would be great full. Thanks :) Input XML: <ROWSET> <ROW> <EMPNO>7839</EMPNO> <ENAME>KING</ENAME> </ROW> </ROWSET> XSL used for transformation: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="no"/> <xsl:template match="/"> <Invitation> <To> <xsl:value-of select="ROWSET/ROW/ENAME"/> </To> </Invitation> </xsl:template>

  • Windows Phone 7 ListBox uncustomizable?

    - by Roy
    I've just recently started development using Visual Studio 2010 Express for Windows Phone and I put in a ListBox. I can't seem to manipulate the formatting. No matter what I do, the background is black/gray, the selected items have a blue border, and there is padding between the items in the listbox (i'm using images). Here is my code: Xaml: <Grid x:Name="ContentGrid" Grid.Row="1"> <Grid Name="gallery"> <Grid.RowDefinitions> <RowDefinition Height="370" /> <RowDefinition Height="150" /> </Grid.RowDefinitions> <Border BorderBrush="Red" Width="450" CornerRadius="4" BorderThickness="2" Background="Red" Margin="10,30,20,10" Padding="6,6,6,6"> <Image Grid.Row="0" Grid.Column="0" Height="360" x:Name="imgPreview"/> </Border> <ListBox x:Name="lbScrollGallery" Grid.Row="1" Grid.Column="0" Padding="0" VerticalAlignment="Top" Width="450" SelectionChanged="ScrollerSelectionChanged" d:LayoutOverrides="HorizontalAlignment" ScrollViewer.HorizontalScrollBarVisibility="Hidden"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.ItemTemplate> <DataTemplate> <Image Width="100" Height="100" Stretch="Fill" Name="imgSource" VerticalAlignment="Center" Source="{Binding Path=Url}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> </Grid> Is there some way I can customize the listbox? Like change the background to red or make the padding between different items 0?

  • using fopen on uploaded file with php

    - by Patrick
    Im uploading a file, and then attempting to use fgetcsv to do things to it. This is my script below. Everything was working fine before i added the file upload portions. Now its not showing any errors, its just not displaying the uploaded data. Im getting my "file uploaded" notice, and the file is saving properly, but the counter for number of entries is showing 0. if(isset($_FILES[csvgo])){ $tmp = $_FILES[csvgo][tmp_name]; $name = "temp.csv"; $tempdir = "csvtemp/"; if(move_uploaded_file($tmp, $tempdir.$name)){ echo "file uploaded<br>"; } $csvfile = $tempdir.$name; $fh = fopen($csvfile, 'r'); $headers = fgetcsv($fh); $data = array(); while (! feof($fh)) { $row = fgetcsv($fh); if (!empty($row)) { $obj = new stdClass; foreach ($row as $i => $value) { $key = $headers[$i]; $obj->$key = $value; } $data[] = $obj; } } fclose($fh); $c=0; foreach($data AS $key){ $c++; $phone = $key->PHONE; $fax = $key->Fax; $email = $key->Email; // do things with the data here } echo "$c entries <br>"; }

  • Sort on DataView does not work if DataTable has zero rows

    - by BigBlondeViking
    We have a WPF app that has a DataGrid insode a ListView. private DataTable table_; We do a bunch or dynamic column generation ( depending on the report we are showing ) We then do the a query and fill the DataTable row by row, this query may or may not have data.( not the problem, an empty grid is expected ) We set the ListView's ItemsSource to the DefaultView of the DataTable. lv.ItemsSource = table_.DefaultView; We then (looking at the user's pass usage of the app, set the sort on the column) Sort Method below: private void Sort(string sortBy, ListSortDirection direction) { var dataView = CollectionViewSource.GetDefaultView(lv.ItemsSource); dataView.SortDescriptions.Clear(); var sd = new SortDescription(sortBy, direction); dataView.SortDescriptions.Add(sd); dataView.Refresh(); } In the Zero DataTable rows scenario, the sort does not "hold"? and if we dynamically add rows they will not be in sorted order. If the DataTable has at-least 1 row when the sort is applied, and we dynamically add rows to the DataTable, the rows com in sorted correctly. I have built a standalone app that replicate this... It is an annoyance and I can add a check to see if the DataTable was empty, and re-sort... Anyone know whats going on here, and am I doing something wrong? FYI: What we based this off if comes from the MSDN as well: http://msdn.microsoft.com/en-us/library/ms745786.aspx

  • SQL ORACLE - Datatable in where clause

    - by Gage
    Currently I have a sql call returning a dataset from a MSSQL database and I want to take a column from that data and return ID's based off that column from the ORACLE database. I can do this one at a time but that requires multiple calls, I am wondering if this can be done with one call. String sql=String.Format(@"Select DIST_NO FROM DISTRICT WHERE DIST_DESC = '{0}'", row.Table.Rows[0]["Op_Centre"].ToString()); Above is the string I am using to return one ID at a time. I know the {0} can be used to format your value into the string and maybe there is a way to do that with a datatable. Also to use multiple values in the where clause it would be: String sql=String.Format(@"Select DIST_NO FROM DISTRICT WHERE DIST_DESC in ('{0}')", row.Table.Rows[0] ["Op_Centre"].ToString()); Although I realize all of this can be done I am wondering if theres an easy way to add it all to the sql string in one call. As I am writing this I am realizing I could break the string into sections then just add every row value to the SQL string within the "WHERE DIST_DESC IN (" clause... I am still curious to see if there is another way though, and because someone else may come across this problem I will post a solution if I develop one. Thanks in advance.

  • SqlLite/Fluent NHibernate integration test harness initialization not repeatable after large data se

    - by Mark Rogers
    In one of my main data integration test harnesses I create and use Fluent NHibernate's SingleConnectionSessionSourceForSQLiteInMemoryTesting, to get a fresh session for each test. After each test, I close the connection, session, and session factory, and throw out the nested StructureMap container they came from. This works for almost any simple data integration test I can think, including ones that utilize Fluent NHib's PersistenceSpecification object. When I test the application's lengthy database bootstrapping process, which creates and saves thousands of domain objects, I start seeing issues. It's not that the setup and tear down fails, in fact, the test successfully bootstraps the in-memory database as the application would bootstrap the real database in the production environment. The problem occurs when the database bootstrapping occurs a second time on a new in-memory database, with a new session and session factory. The error is: NHibernate.StaleStateException : Unexpected row count: 0; expected: 1 The row count is indeed Unexpected, the row that the application under test is looking for should be in the session. You see, it's not that any data from the last integration test is sticking around, it's that for some reason the session just stops working mid-database-boostrap. And I've looked everywhere for a place I might be holding on to an old session and I can't find one. I've searched through the code for static singleton objects, but there are none anywhere near the code in question. I have a couple StructureMap InstanceScope singleton's but they are getting thrown out with each nested container that is lost after every test teardown. I've tried every possible variation on disposing and closing every object involved with each test teardown and it still fails on this lengthy database bootstrap. But non-bootstrap related database tests appear to work fine. I'm starting to run out of options and may have to surrender lengthy database integration tests in favor of WatiN-based acceptance tests. Can anyone give me any clue about how I can figure out why some of my SingleConnectionSessionSourceForSQLiteInMemoryTesting aren't repeatable? Any advice at all, about how to make an NHibernate SqlLite database integration test harness repeatable?
