  • Help with HTML hyperlink please

    - by liz
    Hello, Can someone help me with this problem: I have a table in a jsp page, with the text in one column being hyperlinks. Whenever anyone of these hyperlinks is clicked the whole table should refresh and repopulate based on the value of the hyperlink clicked. My problem is currently when the hyperlink is clicked the page refreshes with an empty table. I have the following line of HTML code for performing this in my jsp page: <TD><A href="http://localhost:8080/pmweb/gui.jsp" onclick="getResults(param)">hyperlinktext</A></TD>; Below is my getResults function in javascript in the same JSP page: <script type="text/javascript"> var httpRequest; function getResults(param) { var url = "http://localhost:8080/pmweb/api/GetResultsByParam?param=" + param; httpRequest = new XMLHttpRequest(); httpRequest.open("GET", url, true); httpRequest.onreadystatechange = function() {processRequest(); } ; httpRequest.send(null); } I have verified that the getResults function above is working fine itself. When I debugged it I noticed that this getResults function is not entered when the hyperlink is clicked. Anyone know how to get the hyperlink calling the javascript function properly? Thanks very much in advance!

  • SQL string manipulation to return multiple rows

    - by Andy Jacobs
    I'm an experienced programmer, but relatively new to SQL. We're using Oracle 10 and 11. I have a system in place using SQL that combines actual rows with virtual rows (e.g. "SELECT 1 from DUAL") doing unions and intersects as needed, which all seems to work. My problem is that I need to combine this system which is expecting rows of data, with new data that will have the data in (let's say for simplification) comma delimited strings. So I think what I need is a way to convert a string like: "5,6,7,8" into 4 rows with one column each, with "5" in the first row, "6" in the second, etc. In other languages, I'd do a "Split" with comma as the delimiter. Of course, the data won't always have 4 entries. There's a second question, but I'll ask it separately. But I suspect it will simplify things, if possible, if the solution to the above could be used as a table in another SQL statement (i.e., to work with my existing system). Thanks for any help.

  • IE8 claims my page has an error, firefox doesn't, and I can't find any error. Help!

    - by Bears will eat you
    This is something of a follow-up question to my question here. You can find the HTML source in a text file here. When I load that page in IE8, I get the "Done, but with errors on page." message in my status bar. The detail view shows Expected identifier sms Line: 147 Code: 0 Char: 67 and I see absolutely no problems anywhere near there. In IE8, the page is still behaving erratically w/r/t the randomly losing focus as mentioned in my other question. When I load the same exact page in Firefox (using Firebug) the console shows no errors and the page works perfectly. Any thoughts on what's going on here? This is driving me nuts and making me want to give up on even trying to write an IE friendly page. Edit: Thanks for all the comments! This page is written as a JSP, so I edit in Eclipse. I found an Eclipse warning about the onblur event for the username field. I switched it from onblur="alert(document.activeElement + ' class:' + document.activeElement.class)" to onblur="alert(document.activeElement)" and that made the bizarre IE page error vanish. I had been trying to give more info (namely, its CSS class) about specifically which element is stealing focus - to my own detriment, apparently, since Javascript was interpreting the '.class' part in the Java(script) sense. And, no, the page doesn't validate. But the errors were mostly/all ones that just didn't make sense, such as Line 14, Column 41: Attribute "LANGUAGE" is not a valid attribute. Did you mean "language"? to which I say, WTF?! But I'm still stuck trying to figure out why, as I enter text in the username & password fields, focus randomly switches to a div (working on figuring out which div currently). Edit 2: It's the div between the two "global nav" comments, at the very top of the body. Still no idea why it's happening, though.

  • Is ADO.NET Entity framework database schema update possible?

    - by fyasar
    I'm working on proof of concept application like crm and i need your some advice. My application's data layer completely dynamic and run onto EF 3.5. When the user update the entity, change relation or add new column to the database, first i'm planning make for these with custom classes. After I rebuild my database model layer with new changes during the application runtime. And my model layer tie with tightly coupled to my project for easy reflecting model layer changes (It connected to my project via interfaces and loading onto to application domain in the runtime). I need to create dynamic entities, create entity relations and modify them during the runtime after that i need to create change database script for updating database schema. I know ADO.NET team says "we will be able to provide this property in EF 4.0", but i don't need to wait for them. How can i update database changes during the runtime via EF 3.5 ? For example, i need to create new entity or need to change some entity schema, add new properties or change property types after than how can apply these changes on the physical database schema ? Any ideas ?

  • How to include many "sub"-queries in a SQL statement to generate file paths for images?

    - by Zachary
    Greetings, I have three fields in legacy MySQL database/application. image_type image_of_bush image_prefix I need to extract the data into a full image file path, into a .CSV file, where each combination (mentioned below) is a column. Can it all be done in SQL? Or can you recommend a better way? Currently using PHP to display the combinations on the product page. this is also part of a larger query, which is extracting data from an OS Commerce mySQL database. CASE ONE One Horizontal Image image_type = "Horizontal Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) CASE TWO One Vertical Image image_type = "Vertical Image" image_of_bush = "No Image of Bush" IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) CASE THREE Two Horizontal Images image_type = "Horizontal Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg) CASE FOUR Two Vertical Images image_type = "Vertical Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FOUR One Horizontal and One Vertical Image image_type = "Horizontal Image" image_of_bush = "Vertical Image of Bush" FIRST IMAGE NAME: image_prefix + _s + .jpg (Example: Albertine_s.jpg) SECOND IMAGE NAME: image_prefix + _bv + .jpg (Example: Albertine_bv.jpg) CASE FIVE One Vertical and One Horizontal Image image_type = "Vertical Image" image_of_bush = "Horizontal Image of Bush" FIRST IMAGE NAME: image_prefix + _v + .jpg (Example: Albertine_v.jpg) SECOND IMAGE NAME: image_prefix + _bs + .jpg (Example: Albertine_bs.jpg)

  • codegen:nullValue vs msprop:nullValue

    - by Ken
    Ok, I have datasets that I created way back in 1.1 framework to which we used codegen:nullValue within the XSD to handle null values. However if I open one of these datasets with vs 2005 (i.e. 2.0 framework) and add a column, it removes the codegen setting from the entire xsd but adds in msprop:nullValue However, unlike previous years, I noticed this time the proper property code was NOT over riden from returning the null value specified in codegen as it was doing in the past. Meaning the msprop appears to be creating the proper code behind the scenes (See example). Anyone know of any other differnces? Should I be concerned with deploying a new xsd, WITHOUT the codegen code but instead with the msprop xml? Example: Original creates _ Public Property ParentID() As Integer Get If Me.IsParentIDNull Then Return -1 Else Return CType(Me(Me.tableCompany.ParentIDColumn),Integer) End If End Get Set Me(Me.tableCompany.ParentIDColumn) = value End Set End Property New creates _ Public Property ParentID() As Integer Get If Me.IsParentIDNull Then Return -1 Else Return CType(Me(Me.tableCompany.ParentIDColumn),Integer) End If End Get Set Me(Me.tableCompany.ParentIDColumn) = value End Set End Property BUT is there anything else that might be occuring that I am NOT seeing thus MAKING me re-enter all the codegen settings? THANKS!

  • Exporting WPF DataGrid to a text file in a nice looking format. Text file must be easy to read.

    - by Andrew
    Hi, Is there a simple way to export a WPF DataGrid to a text file and a .csv file? I've done some searching and can't see that there is a simple DataGrid method to do so. I have got something working (barely) by making use of the ItemsSource of the DataGrid. In my case, this is an array of structs. I do something with StreamWriters and StringBuilders (details available) and basically have: StringBuilder destination = new StringBuilder(); destination.Append(row.CreationDate); destination.Append(seperator); // seperator is '\t' or ',' for csv file destination.Append(row.ProcId); destination.Append(seperator); destination.Append(row.PartNumber); destination.Append(seperator); I do this for each struct in the array (in a loop). This works fine. The problem is that it's not easy to read the text file. The data can be of different lengths within the same column. I'd like to see something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 And of course, I get something like: 2007-03-03 234238423823 823829923 2007-03-03 66 99 It's not surprising giving that I'm using Tab delimiters, but I hope to do better. It certainly is easy to read in the DataGrid! I could of course have some logic to pad short values with spaces, but that seems quite messy. I thought there might be a better way. I also have a feeling that this is a common problem and one that has probably been solved before (hopefully within the .NET classes themselves). Thanks.

  • [PHP] Kohana-v3 ORM parent relationship

    - by VDVLeon
    Hi all, I just started with the version 3 of the Kohana Framework. I have worked a little with the $_has_many etc. Now I have the table pages. The primary key is pageID. The table has a column called parentPageID. Now I want to make a ORM model who, when accesed like this $page->parent->find() returns the page identified by parentPageID. I have the following already: // Settings protected $_table_name = 'pages'; protected $_primary_key = 'pageID'; protected $_has_one = array( 'parent' => array( 'model' => 'page', 'foreign_key' => 'parentPageID', ), ); But that does not work, it simply returns the first page from the table. Last query says this: SELECT `pages`.* FROM `pages` ORDER BY `pages`.`pageID` ASC LIMIT 1 Does somebody know how to solve this? I know this can: $parent = $page->parent->find($page->parentPageID); but it must be and can be cleaner (I think).

  • Advice Please: SQL Server Identity vs Unique Identifier keys when using Entity Framework

    - by c.batt
    I'm in the process of designing a fairly complex system. One of our primary concerns is supporting SQL Server peer-to-peer replication. The idea is to support several geographically separated nodes. A secondary concern has been using a modern ORM in the middle tier. Our first choice has always been Entity Framework, mainly because the developers like to work with it. (They love the LiNQ support.) So here's the problem: With peer-to-peer replication in mind, I settled on using uniqueidentifier with a default value of newsequentialid() for the primary key of every table. This seemed to provide a good balance between avoiding key collisions and reducing index fragmentation. However, it turns out that the current version of Entity Framework has a very strange limitation: if an entity's key column is a uniqueidentifier (GUID) then it cannot be configured to use the default value (newsequentialid()) provided by the database. The application layer must generate the GUID and populate the key value. So here's the debate: abandon Entity Framework and use another ORM: use NHibernate and give up LiNQ support use linq2sql and give up future support (not to mention get bound to SQL Server on DB) abandon GUIDs and go with another PK strategy devise a method to generate sequential GUIDs (COMBs?) at the application layer I'm leaning towards option 1 with linq2sql (my developers really like linq2[stuff]) and 3. That's mainly because I'm somewhat ignorant of alternate key strategies that support the replication scheme we're aiming for while also keeping things sane from a developer's perspective. Any insight or opinion would be greatly appreciated.

  • jquery - array problem help pls.

    - by russp
    Sorry folks, I really need help with posting an array problem. I would imaging it's quite simple, but beyond me. I have this JQuery function (using sortables) $(function() { $("#col1, #col2, #col3, #col4").sortable({ connectWith: '.column', items: '.portlet:not(.ui-state-disabled)', stop : function () { serial_1 = $('#col1').sortable('serialize'); serial_2 = $('#col2').sortable('serialize'); serial_3 = $('#col3').sortable('serialize'); serial_4 = $('#col4').sortable('serialize'); } }); }); Now I can post it to a database like this, and I can loop this ajax through all 4 "serials" $.ajax({ url: "test.php", type: "post", data: serial_1, error: function(){ alert(testit); } }); But that is not what I want to do as it creates 4 rows in the DB table. I want/need to create a single "nested array" from the 4 serials so that it enters the DB as 1 (one) row. My "base" database data looks like this: a:4:{s:4:"col1";a:3:{i:1;s:6:"forums";i:2;s:4:"chat";i:3;s:5:"blogs";}s:4:"col2";a:2:{i:1;s:5:"pages";i:2;s:7:"members";}s:4:"col3";a:2:{i:1;s:9:"galleries";i:2;s:4:"shop";}s:4:"col4";a:1:{i:1;s:4:"news";}} Therefore the JQuery array should "replicate" and create it (obviously will change on sorting) Help please thanks in advance

  • How to restrict a content of string to less than 4MB and save that string in DB using C#

  • Building Stored Procedure to group data into ranges with roughly equal results in each bucket

    - by Len
    I am trying to build one procedure to take a large amount of data and create 5 range buckets to display the data. the buckets ranges will have to be set according to the results. Here is my existing SP GO /****** Object: StoredProcedure [dbo].[sp_GetRangeCounts] Script Date: 03/28/2010 19:50:45 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_GetRangeCounts] @idMenu int AS declare @myMin decimal(19,2), @myMax decimal(19,2), @myDif decimal(19,2), @range1 decimal(19,2), @range2 decimal(19,2), @range3 decimal(19,2), @range4 decimal(19,2), @range5 decimal(19,2), @range6 decimal(19,2) SELECT @myMin=Min(modelpropvalue), @myMax=Max(modelpropvalue) FROM xmodelpropertyvalues where modelPropUnitDescriptionID=@idMenu set @myDif=(@myMax-@myMin)/5 set @range1=@myMin set @range2=@myMin+@myDif set @range3=@range2+@myDif set @range4=@range3+@myDif set @range5=@range4+@myDif set @range6=@range5+@myDif select @myMin,@myMax,@myDif,@range1,@range2,@range3,@range4,@range5,@range6 select t.range as myRange, count(*) as myCount from ( select case when modelpropvalue between @range1 and @range2 then 'range1' when modelpropvalue between @range2 and @range3 then 'range2' when modelpropvalue between @range3 and @range4 then 'range3' when modelpropvalue between @range4 and @range5 then 'range4' when modelpropvalue between @range5 and @range6 then 'range5' end as range from xmodelpropertyvalues where modelpropunitDescriptionID=@idmenu) t group by t.range order by t.range This calculates the min and max value from my table, works out the difference between the two and creates 5 buckets. The problem is that if there are a small amount of very high (or very low) values then the buckets will appear very distorted - as in these results... range1 2806 range2 296 range3 75 range5 1 Basically I want to rebuild the SP so it creates buckets with equal amounts of results in each. I have played around with some of the following approaches without quite nailing it... SELECT modelpropvalue, NTILE(5) OVER (ORDER BY modelpropvalue) FROM xmodelpropertyvalues - this creates a new column with either 1,2,3,4 or 5 in it ROW_NUMBER()OVER (ORDER BY modelpropvalue) between @range1 and @range2 ROW_NUMBER()OVER (ORDER BY modelpropvalue) between @range2 and @range3 or maybe i could allocate every record a row number then divide into ranges from this?

  • Can I flow divs down the page instead of across it?

    - by Brabster
    If I have a collection of div elements, I can use CSS to have them flow across the page and overflow onto the next line. Here's a simple example: <html> <head> <title>Flowing Divs</title> <style type="text/css"> .flow { float: left; margin: 4em 8em; } </style> </head> <body> <div class="container"> <div class="flow">Div 1</div> <div class="flow">Div 2</div> <div class="flow">Div 3</div> <div class="flow">Div 4</div> <div class="flow">Div 5</div> <div class="flow">Div 6</div> <div class="flow">Div 7</div> <div class="flow">Div 8</div> </div> </body> </html> Is it possible to have the divs flow down the page instead of across it, so that they would flow down columns not along lines, but still occupy the same space as they would if they flowed across? So for the example above, if they flowed into two lines of four divs, could I get the first column to contain Div1 and Div2 instead of Div1 and Div5?

  • How to use Nhibernate Validator + NHib component + ddl

  • SharePoint: Filtering a List that has Folders

    - by Gary McGill
    I have a SharePoint document library that has a folder structure used for organizing the documents (but also for controlling access, via permissions on the folders). The documents in the library are updated every month, and we store every month's version of the document in the same folder; there's a "month" column used for filtering that will contain values like Jan 09, Feb 09, etc. It looks like this: Title Month ----- ----- SubFolder 1 SubFolder 2 [] Interesting Facts Jan 09 [] Interesting Facts Feb 09 [] Interesting Facts Mar 09 [] Fascinating Numbers Jan 09 [] Fascinating Numbers Feb 09 ... Now, because users will generally be most interested in the 'current' month, I'd like them to be able to apply a filter, and select (say) Mar 09. However, if they do this using the built-in filtering, it also filters out the folders, and they can no longer navigate the folder hierarchy. This is no good - I want them to be able to move between folders with the filter intact, so that they don't need to keep switching it off and on again. I figured I might be able to use a custom view (selecting where type=folder or month=[month]), and to an extent that does work. However, I can only get it to work for a fixed month, whereas I need the user to be able to select the month - perhaps via a drop-down control on the page (and I don't want to create 60 views for 5 years' worth of months, nor do I want to have to create a new view every month). I thought it might be possible to create a view in code (rather than via the UI), but I've not been able to figure out how to get a dynamic value (a user-specific setting) into the CAML query. Any pointers gratefully appreciated! And by the way, I am aware of the dogma that folders are bad, and that everything should just be a list. However, having considered the alternatives, I still favour using folders - if I can solve this problem. Thanks in advance.

  • R : remove columns from dataframe where ALL values are NA

    - by Sophomore
    hello everybody! I'm having some trouble with my huge data frame and couldn't really resolve that question myself: The dataframe has some properties as columns and each row represents one data set. I've done some sanatizing to this dataframe (e.g. get rid of datasets which are not to be included in evaluation). (Whoever might be interested: Beforehand I aggregate around 5000 single text files and put them in a tsv, some of the proerties have a sequence number like "button.pressed.1" ... ""button.pressed.n". Some of the sets excluded had really high numbers for n but got excluded, all sets left have much smaller numbers for n but the property "button.presed.50" is still there and all remaining sets have an NA in that column. Actually its a different property but the example should clarify my intention...) So the question is quite simple (for some sophisticated R pro): I need to get rid of columns where for ALL rows the value is NA. Could someone please help me out? (All I have managed to get rid of columns where at least one NA exists which dropped about half my columns)...

  • A "smart" (forgiving) date parser?

    - by jdmuys
    I have to migrate a very large dataset from one system to another. One of the "source" column contains a date but is really a string with no constraint, while the destination system mandates a date in the format yyyy-mm-dd. Many, but not all, of the source dates are formatted as yyyymmdd. So to coerce them to the expected format, I do (in Perl): return "$1-$2-$3" if ($val =~ /(\d{4})[-\/]*(\d{2})[-\/]*(\d{2})/); The problem arises when the source dates moves away from the "generic" yyyymmdd. The goal is to salvage as many dates as possible, before giving up. Example source strings include: 21/3/1998, March 2004, 2001, 3/4/97 I can try to match as many of the examples I can find with a succession of regular expressions such as the one above. But is there something smarter to do? Am I not reinventing the wheel? Is there a library somewhere doing something similar? I couldn't find anything relevant googling "forgiving date parser". (any language is OK).

  • How do I bind arrays to columns in a WPF datagrid

    - by user1432917
    I have a Log object that contains a list of Curve objects. Each curve has a Name property and an array of doubles. I want the Name to be in the column header and the data below it. I have a user control with a datagid. Here is the XAML; <UserControl x:Class="WellLab.UI.LogViewer" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="500" d:DesignWidth="500"> <Grid> <StackPanel Height="Auto" HorizontalAlignment="Stretch" Margin="0" Name="stackPanel1" VerticalAlignment="Stretch" Width="Auto"> <ToolBarTray Height="26" Name="toolBarTray1" Width="Auto" /> <ScrollViewer Height="Auto" Name="scrollViewer1" Width="Auto" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Visible" CanContentScroll="True" Background="#E6ABA4A4"> <DataGrid AutoGenerateColumns="True" Height="Auto" Name="logDataGrid" Width="Auto" ItemsSource="{Binding}" HorizontalAlignment="Left"> </DataGrid> </ScrollViewer> </StackPanel> </Grid> In the code behind I have figured out how to create columns and name them, but I have not figured out how to bind the data. public partial class LogViewer { public LogViewer(Log log) { InitializeComponent(); foreach (var curve in log.Curves) { var data = curve.GetData(); var col = new DataGridTextColumn { Header = curve.Name }; logDataGrid.Columns.Add(col); } } } I wont even show the code I tried to use to bind the array "data", since nothing even came close. I am sure I am missing something simple, but after hours of searching the web, I have to come begging for an answer.

  • Tree data in MySql database table

    - by Robert Koritnik
    I have a table that uses Adjacency list model for hierarchy storage. My most relevant columns in this table are therefore: ItemId // is auto_increment ParentId Level ParentTrail // in the form of "parentId/../parentId/itemId" then I created a before insert tigger, that populates columns Level and ParentTrail. Since the last column also includes current item's ID I had to use a trick in my trigger because auto_increment columns are not available in the before insert trigger. So I get that value from the information_schema.tables table. All works fine, until I try to write an update trigger, that would update my item and its descendants when the item changes its parent (ParentId has changed). But I can't make an update on my table inside the update trigger. All I can do is to change current record's values but not other's. I could use a separate table for hierarchy data, but that would mean that I would also have to create a view that would combine these two tables (1:1 relation) and I would like to avoid this is at all possible. Is there a way to have all these in the same table so that these fields (Level and ParetTrail) set/update themselves automagically using triggers?

  • DataGridView with row-specific DataGridViewComboBoxColumn contents

    - by XXXXX
    So I have something like the following data structure (constructors omitted) class Child { public string Name { get; set; } public int Age { get; set; } } class Parent { public string Name { get; set; } public List <Child> Children { get; private set; } // never null; list never empty public Child FavoriteChild { get; set; } // never null; always a reference to a Child in Children } List < Parent > Parents; What I want to do is show a DataGridView where each row is a Parent from Parent list. Each row should have two columns: a text box showing the parent's name and a DataGridViewComboBoxColumn containing that parent's children, from which the user can select the parent's favorite child. I suppose I could do the whole thing manually, but I'd like to do all this with more-or-less standard Data Binding. It's easy enough to bind the DataGridView to the list of parents, and easy enough to bind the selected child to the FavoriteChild property. The part that's giving me difficulty is that it looks like the Combo Box column wants to bind to one data source for all the combo-box's contents on all rows. I'd like each instance of the combo box to bind to the list of each parent's children. I'm fairly new to C#/Windows Forms, so I may well be missing something obvious. Or it could be that "you can't get there from here." It's not too tough to make a separate list of all the children and filter it by parent; I'm looking into that possibility right now. Is this feasible, or is there a better way?

  • Getting wierd issue with TO_NUMBER function in Oracle

    - by Fazal
    I have been getting an intermittent issue when executing to_number function in the where clause on a varchar2 column if number of records exceed a certain number n. I used n as there is no exact number of records on which it happens. On one DB it happens after n was 1 million on another when it was 0.1. million. E.g. I have a table with 10 million records say Table Country which has field1 varchar2 containing numberic data and Id If I do a query as an example select * from country where to_number(field1) = 23 and id 1 and id < 100000 This works But if i do the query select * from country where to_number(field1) = 23 and id 1 and id < 100001 It fails saying invalid number Next I try the query select * from country where to_number(field1) = 23 and id 2 and id < 100001 It works again As I only got invalid number it was confusing, but in the log file it said Memory Notification: Library Cache Object loaded into SGA Heap size 3823K exceeds notification threshold (2048K) KGL object name :with sqlplan as ( select c006 object_owner, c007 object_type,c008 object_name from htmldb_collections where COLLECTION_NAME='HTMLDB_QUERY_PLAN' and c007 in ('TABLE','INDEX','MATERIALIZED VIEW','INDEX (UNIQUE)')), ws_schemas as( select schema from wwv_flow_company_schemas where security_group_id = :flow_security_group_id), t as( select s.object_owner table_owner,s.object_name table_name, d.OBJECT_ID from sqlplan s,sys.dba_objects d It seems its related to SGA size, but google did not give me much help on this. Does anyone have any idea about this issue with TO_NUMBER or oracle functions for large data?

  • WPF ContextMenu bind some property to another property of the same control

    - by bebicasoft
    I have a ContextMenu and a ColumnHeaderStyle defined in Window.Resource section witch i use-it to a DataGrid ColumnHeader. My code is something like this: <ContextMenu x:Key="cm_columnHeaderMenu"/> <Style x:Key="DefaultColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Setter Property="ContextMenu" Value="{StaticResource cm_columnHeaderMenu}" /> </Style> <DataGrid Grid.Column="2" Grid.Row="1" x:Name="dgridFiles" IsReadOnly="True" ColumnHeaderStyle="{StaticResource DefaultColumnHeaderStyle}"> I want to know if I can (and if the answer it true, then HOW I could do it) bind the ContextMenu Visibility property to same control ContextMenu Items.Count>0 property. Initially based on some other treeView control selections made there shoud be no items in the context menu, but i wish to add dinamically items in ContextMenu based on selection in treeView. This part is done, the context has those items. On some selections there are no-items, but still on the grid it appears an empty ContextMenu. So I believe the easiest part it would be to bind the Visibility to Items.Count property of the same control. Sorry if my english is not good enought, I'll try to explain better if i didnt make clear 1st time.

  • Cannot open database "DataDir" requested by the login. The login failed

    Hi, I have a single user software that uses SQL Server database 2005. My computer was crushed while my software was on. I saved a copy of my database after I rescued my computer.
