  • Word VBA - Find text between delimiters and convert to lower case

    - by jJack
    I would like to find text which is between the < and characters, and then turn any found text into "normal" case, where first letter of word is capitalized. Here is what I have thus far: Function findTextBetweenCarots() As String Dim strText As String With Selection .Find.Text = "<" ' what about <[^0-9]+> ? .Find.Forward = True .Find.Wrap = wdFindContinue End With Selection.Find.Execute ' Application.Selection. ' how do I get the text between the other ">"? findCarotSymb = Application.Selection.Text End Function Or, is there a better way of doing this? I also approached the problem using the VBScript Regex 5.5 library, which worked on simple documents, but not on certain documents with complex tables. For example, trying to just bold the text (for simplicity): Sub BoldUpperCaseWords() Dim regEx, Match, Matches Dim rngRange As Range Set regEx = New RegExp regEx.Pattern = "<[^0-9]+>" regEx.IgnoreCase = False regEx.Global = True Set Matches = regEx.Execute(ActiveDocument.Range.Text) For Each Match In Matches ActiveDocument.Range(Match.FirstIndex, Match.FirstIndex + Len(Match.Value)).Bold = True Next End Sub would not work in a document with tables. In fact, it would not even bold the correct text (the text between the <. This leads me to believe I have a broader issue here that I am missing. Here is what a sample doc looks like. Notice the wrong text is bold:

  • Firefox drags div like it was an image, javascript event handlers possibly to blame

    - by user281434
    Hi, I'm using this HTML,CSS and Javascript code (in one document together if you want to test it out): <style type="text/css"> #slider_container { width: 200px; height: 30px; background-color: red; display:block; } #slider { width: 20px; height: 30px; background-color: blue; display:block; position:absolute; left:0; } </style> <script type="text/javascript" src="../../js/libs/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#slider").mousedown(function() { $(document).mousemove(function(evnt) { $("#test").html("sliding"); }).mouseup(function() { $("#test").html("not sliding"); $(document).unbind("mousemove mouseup"); });}); }); </script> <div id="test">a</div> <div id="slider_container"> <div id="slider"></div> </div> Everything (surprisingly) works fine in IE, but firefox seems to totally clusterf*ck when this javascript is used. The first "slide" is okay, you drag, it says "sliding", you drop, it says "not sliding". On the second "slide" (or mousedown if you will), firefox suddenly thinks the div is an image or link and wants to drag it around. Screenshot of the dragging: http://i.imgur.com/nPJxZ.jpg Obviously the blue div half-positioned in the red div is the one being dragged. Windows does not capture the cursor when you take a screenshot, but it's a stop sign. Is there someway to prevent this default behaviour?

  • SQL Server 2008 alternative for SQL-DMO

    - by alexdelpiero
    Hi! I previously was using SQL-DMO to automatically generate scripts from the database. Now I upgraded to SQL Server 2008 and I don’t want to use this feature anymore since Microsoft will be dropping this feature off. Is there any other alternative I can use to connect to a server and generate scripts automatically from a database? Any answer is welcome. Thanks in advance. This is the procedure i was previously using: CREATE PROC GenerateSP ( @server varchar(30) = null, @uname varchar(30) = null, @pwd varchar(30) = null, @dbname varchar(30) = null, @filename varchar(200) = 'c:\script.sql' ) AS DECLARE @object int DECLARE @hr int DECLARE @return varchar(200) DECLARE @exec_str varchar(2000) DECLARE @spname sysname SET NOCOUNT ON -- Sets the server to the local server IF @server is NULL SELECT @server = @@servername -- Sets the database to the current database IF @dbname is NULL SELECT @dbname = db_name() -- Sets the username to the current user name IF @uname is NULL SELECT @uname = SYSTEM_USER -- Create an object that points to the SQL Server EXEC @hr = sp_OACreate 'SQLDMO.SQLServer', @object OUT IF @hr <> 0 BEGIN PRINT 'error create SQLOLE.SQLServer' RETURN END -- Connect to the SQL Server IF @pwd is NULL BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname IF @hr <> 0 BEGIN PRINT 'error Connect' RETURN END END ELSE BEGIN EXEC @hr = sp_OAMethod @object, 'Connect', NULL, @server, @uname, @pwd IF @hr <> 0 BEGIN PRINT 'error Connect' RETURN END END --Verify the connection EXEC @hr = sp_OAMethod @object, 'VerifyConnection', @return OUT IF @hr <> 0 BEGIN PRINT 'error VerifyConnection' RETURN END SET @exec_str = 'DECLARE script_cursor CURSOR FOR SELECT name FROM ' + @dbname + '..sysobjects WHERE type = ''P'' ORDER BY Name' EXEC (@exec_str) OPEN script_cursor FETCH NEXT FROM script_cursor INTO @spname WHILE (@@fetch_status <> -1) BEGIN SET @exec_str = 'Databases("'+ @dbname +'").StoredProcedures("'+RTRIM(UPPER(@spname))+'").Script(74077,"'+ @filename +'")' EXEC @hr = sp_OAMethod @object, @exec_str, @return OUT IF @hr <> 0 BEGIN PRINT 'error Script' RETURN END FETCH NEXT FROM script_cursor INTO @spname END CLOSE script_cursor DEALLOCATE script_cursor -- Destroy the object EXEC @hr = sp_OADestroy @object IF @hr <> 0 BEGIN PRINT 'error destroy object' RETURN END GO

  • How can I get a distinct list of elements in a hierarchical query?

    - by RenderIn
    I have a database table, with people identified by a name, a job and a city. I have a second table that contains a hierarchical representation of every job in the company in every city. Suppose I have 3 people in the people table: [name(PK),title,city] Jim, Salesman, Houston Jane, Associate Marketer, Chicago Bill, Cashier, New York And I have thousands of job type/location combinations in the job table, a sample of which follow. You can see the hierarchical relationship since parent_title is a foreign key to title: [title,city,pay,parent_title] Salesman, Houston, $50000, CEO Cashier, Houston, $25000 CEO, USA, $1000000 Associate Marketer, Chicago, $75000 Senior Marketer, Chicago, $125000 ..... The problem I'm having is that my Person table is a composite key, so I don't know how to structure the start with part of my query so that it starts with each of the three jobs in the cities I specified. I can execute three separate queries to get what I want, but this doesn't scale well. e.g.: select * from jobs start with city = (select city from people where name = 'Bill') and title = (select title from people where name = 'Bill') connect by prior parent_title = title UNION select * from jobs start with city = (select city from people where name = 'Jim') and title = (select title from people where name = 'Jim') connect by prior parent_title = title UNION select * from jobs start with city = (select city from people where name = 'Jane') and title = (select title from people where name = 'Jane') connect by prior parent_title = title How else can I get a distinct list (or I could wrap it with a distinct if not possible) of all the jobs which are above the three people I specified?

  • Algorithms for finding a numerical record in a list of ordered numbers

    - by Ankur
    I have a list of incomplete ordered numbers. I want to find a particular number with as few steps as possible. Are there any improvements on this algorithm, I assume you can count the set size without difficulty - it will be stored and updated every time a new item is added. Your object is to get your cursor over the value x The first number (smallest) is s, and the last number (greatest) is g. Take the midpoint m1 of the set: calculate is x < m1, If yes then s <= x < m1 If no then m1 < x <= g If m1 = x then you're done. Keep repeating till you find x. Basically dividing the set into two parts with each iteration till you hit x. The purpose is to retrieve a numerical id from a very large table to then find the associated other records. I would imagine this is the most trivial kind of indexing available, are there improvements?

  • WPF Designer has bug with parsing generic control with overrided property

    - by Ivan Laktyunkin
    I've created a generic lookless control with virtual property: public abstract class TestControlBase<TValue> : Control { public static readonly DependencyProperty ValueProperty; static TestControlBase() { ValueProperty = DependencyProperty.Register("Value", typeof(TValue), typeof(TestControlBase<TValue>)); } protected TestControlBase() { Focusable = false; Value = default(TValue); } public virtual TValue Value { get { return (TValue)GetValue(ValueProperty); } set { SetValue(ValueProperty, value); } } } Then I've made a control derived from it and overrided Value property: public class TestControl : TestControlBase<int> { public override int Value { get { return base.Value; } set { base.Value = value; } } } So I use it in a Window XAML: <TestControls:TestControl /> When I open window in designer all is OK, but when I put mouse cursor to this line, or to this control in designer I receive exception: Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) Ambiguous match found. at System.RuntimeType.GetPropertyImpl(String name, BindingFlags bindingAttr, Binder binder, Type returnType, Type[] types, ParameterModifier[] modifiers) at System.Type.GetProperty(String name) at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsDirect() at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsAttached() at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties(Attribute[] attributes) at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultExtendedTypeDescriptor.System.ComponentModel.ICustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute[] attributes, Boolean noCustomTypeDesc, Boolean noAttributes) at System.ComponentModel.TypeDescriptor.GetProperties(Object component) at MS.Internal.Model.ModelPropertyCollectionImpl.GetProperties(String propertyNameHint) at MS.Internal.Model.ModelPropertyCollectionImpl.<GetEnumerator>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.Model.ModelPropertyMerger.<GetFirstProperties>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.PropertyInspector.UpdateCategories(Selection selection) at MS.Internal.Designer.PropertyEditing.PropertyInspector.OnSelectionChangedIdle() Who know this problem?

  • Logging exceptions during bean injection

    - by Marc W
    I think this is a pretty basic question, but after Googling around I can't seem to find the answer. What I need is a way to log some custom output with log4j during Spring bean construction. I have a factory class called ResponderFactory (being used as an instance factory in Spring) with a factory method that can throw 2 different types of exception. public CollectorResponder collectorResponder(String inputQueueName) throws ConfigurationException, BrokerConnectionException {} Now, normally I could wrap a call to this method in a try-catch block with 2 catch clauses to handle the logging situations for each of the exceptions. However, if I'm using Spring to inject this CollectorResponder, created with the factory, into another class I don't see how this is possible. <bean id="responderFactory" class="com.package.ResponderFactory"> <constructor-arg index="0" ref="basicDispatcher" /> <constructor-arg index="1" value="http://localhost:9000" /> </bean> <bean id="collectorResponder" class="com.package.CollectorResponder" factory-bean="responderFactory" factory-method="collectorResponder"> <constructor-arg value="collector.in" /> </bean> <bean id="collectorConsumer" class="com.package.CollectorConsumer"> <constructor-arg ref="collectorResponder" /> </bean> Again, I want to catch these exceptions when the collectorResponder bean is instantiated. Right now I'm dealing with this is CollectorConsumer when I instantiate using new CollectorResponder(...). Is there any way I can do this?

  • How do set up jquery to exclude classes in a function?

    - by user1497158
    I essentially only understand how to read bits of javascript and make modifications. I am using grid-slider, a script I purchased, but the code writer is mia at the moment, so hopefully someone here can help me. Basically, it's a slider and there are options to have links open like normal or to have links open in a panel on the same page. I want some links to open in a panel and others to open in the parent window. It seems to me that all that would be required to do this would be to activate the panel display function (which I've done) and then set up an exclude function to exclude certain uls or lis with a specific class from the function. I've read about the .not selector, but I don't see how to make it applicable to this code: enter code hereelse { enter code here if (this._displayOverlay) { if ($item.find(">.content").size() > 0) { $item.data("type", "static"); } else { var contentType = this.getContentType($link); var url = $link.attr("href"); $item.data({type:contentType, url:(typeof url != "undefined") ? url : ""}); } $item.css("cursor", "pointer").bind("click", {elem:this, i:i}, this.openOverlay); } $link.data("text", $item.find(">div:first").html()); $img = $link.find(">img"); } Can anyone help based on looking at this? Here's a link to the demo of the code: http://codecanyon.net/item/jquery-grid-style-slider/full_screen_preview/1204040 Thank you.

  • How do I keep child elements together with parent jQuery sortable.

    - by unknowndomain
    I have a list of items like this... <ol> <li> <span></span> <img src="image.png" /> <p>Image Caption</p> </li> </ol> And I want to be able to sort the LI's but not the sub elements, they should just move with their parent. I am using the jQuery to do that... $('ol li').sortable({ 'cursor': 'move' }); And its working but not moving the whole lot just the element you clicked i.e. the <p>, <img> or <span> I can't figure out how to solve this so I looked about and found an option called 'items': '> li' which was recommended but upon using this nothing drags any more but using firebug + jquery plugin I can see there is a sortable on the <li> still. Not sure what to do, example here: http://clareshilland.unknowndomain.co.uk/ Press ctrl+l to login. Enter the login details: Username: clarePassword: demo Select 'edit' from under then 'image' portion of the menu. The sortables should be those polaroids. Thanks in advance, another one I've been banging my head on the table with.

  • css hover vs. javascript mouseover

    - by John
    There are times when I have a choice between using a css element:hover or javascript onmouseover to control the appearance of html elements on a page. Consider the following scenario where a DIV wraps an INPUT <div> <input id="input"> </div> I want the input to change background color when the mouse cursor hovers over the div. The CSS approach is <style> input {background-color:White;} div:hover input {background-color:Blue;} </style> <div><input></div> The javascript approach is <div onmouseover="document.getElementById('input').style.backgroundColor='Blue';"> <input id="input"> </div> What are the advantages and disadvantages of each approach? Does the CSS approach work well with most web browsers? Is javascript slower than css?

  • Fancybox close button not showing when using different template

    - by VeraG
    I have a page where I need to use 2 different FancyBox styles for different elements on the page. To achieve that, I added tpl option and modified stylesheet accordingly. Here is what I have: $(document).ready(function() { $(".login").fancybox({ closeClick : false, closeBtn : true, tpl: { wrap : '<div class="fancybox-wrap1" tabIndex="-1"><div class="fancybox-skin1"><div class="fancybox-outer"><div class="fancybox-inner"></div></div></div></div>', closeBtn : '<a title="Close" class="fancybox-item fancybox-close" href="javascript:;"></a>' } }); }); In my CSS, I added new styles for .fancybox-wrap1 and .fancybox-skin1. Styles work great BUT on the FancyBox with modified template "close" button completly disappears! I tried both adding and deleting closeBtn from tpl but it doesn't seem to make any difference. I also have a demo here (eventually I will need different background-images for FancyBox, not just background-color, that's why I'm doing it). What am I doing wrong? Any help will be greatly appreciated!

  • Jqplot ajax request

    - by Moozy
    I'm trying to do a dynamic content load for JQplot charts, but something is wrong: this is my javascript code: $(document).ready(function(){ var ajaxDataRenderer = function(url, plot, options) { var ret = null; $.ajax({ // have to use synchronous here, else the function // will return before the data is fetched async: false, url: url, dataType:"json", success: function(data) { ret = data; console.warn(data); } }); return ret; }; // The url for our json data var jsonurl = "getData.php"; var plot1 = $.jqplot('chart1', jsonurl, { title:'Data Point Highlighting', dataRenderer: ajaxDataRenderer, dataRendererOptions: { unusedOptionalUrl: jsonurl }, axes:{ xaxis: { renderer:$.jqplot.DateAxisRenderer, min: '11/01/2012', max: '11/30/2012', tickOptions:{formatString:'%b %#d'}, tickInterval:'5 days' }, yaxis:{ tickOptions:{ formatString:'%.2f' } } }, highlighter: { show: true, sizeAdjust: 7.5 }, cursor: { show: false } }); }); </script> and it is displaying the chart, but it is not displaying the values, looklike its not getting my data. output of: console.warn(data); is: [["11-01-2012",0],["11-02-2012",0],["11-03-2012",0],["11-04-2012",0],["11-05-2012",0],["11-06-2012",0],["11-07-2012",0],["11-08-2012",0],["11-09-2012",0],["11-10-2012",0],["11-11-2012",0],["11-12-2012",0],["11-13-2012",0],["11-14-2012",0],["11-15-2012",2],["11-16-2012",5],["11-17-2012",0],["11-18-2012",1],["11-19-2012",0],["11-20-2012",0],["11-21-2012",0],["11-22-2012",0],["11-23-2012",0],["11-24-2012",0],["11-25-2012",1],["11-26-2012",0],["11-27-2012",0],["11-28-2012",0],["11-29-2012",0],["11-30-2012",0]]

  • NetBeans Tips and Tricks

    - by cdmckay
    I just saw an Eclipse tips & tricks post and was wondering if anyone had any tips & tricks for my IDE of choice: NetBeans. Here's a few I know and find to be useful: Removing a package: After you remove a package in NetBeans, it sticks around as a grayed-out package in your Project view. To get rid of that, switch to Files view and delete the directory. Alt-Insert (in Windows) opens up a Generate submenu at your cursor. A nice shortcut for quickly generating getters/setters (among other things). Selecting a chunk of code, right-clicking and then clicking "Refactor Introduce Method" will have NetBeans introduce a method, complete with arguments and return value. Of course you have to make sure the chunk of code only has one return value. Sometimes when you run a build and it crashes, the Java window sticks around at the bottom. I used to just click X until Windows let me End Task, but there's a nicer way to get rid of them. Click "Run Stop Build/Run" and NetBeans will close the window for you. It'll even let you close multiple applications at once. These may seem obvious to grizzled NetBeans developers, but I thought they might be useful for NetBeans newbs like me. Anyone else have any tips/tricks to share? Here are some from the comments: NetBeans allows for code templates. You can even add yours on the Code Templates tab under the Editor settings on the Options window. Some examples: Type sout and hit the tab key as a shorcut for System.out.println("") Type psvm and hit the tab key as a shorcut for public static void main(String args[]) {} Ctrl Shift C: Comments out the selected block of code. Alt Shift F: Formats the selected block of code. Ctrl E: Deletes current line. Ctrl Shift I: Fixes your imports, handy if you've just written a piece of code that needs a lot of packages imported.

  • How to refactor use of the general Exception?

    - by Colin
    Our code catches the general exception everywhere. Usually it writes the error to a log table in the database and shows a MessageBox to the user to say that the operation requested failed. If there is database interaction, the transaction is rolled back. I have introduced a business logic layer and a data access layer to unravel some of the logic. In the data access layer, I have chosen not to catch anything and I also throw ArgumentNullExceptions and ArgumentOutOfRangeExceptions so that the message passed up the stack does not come straight from the database. In the business logic layer I put a try catch. In the catch I rollback the transaction, do the logging and rethrow. In the presentation layer there is another try catch that displays a MessageBox. I am now thinking about catching a DataException and an ArgumentException instead of an Exception where I know the code only accesses a database. Where the code accesses a web service, then I thought I would create my own "WebServiceException", which would be created in the data access layer whenever an HttpException, WebException or SoapException is thrown. So now, generally I will be catching 2 or 3 exceptions where currently I catch just the general Exception, and I think that seems OK to me. Does anyone wrap exceptions up again to carry the message up to the presentation layer? I think I should probably add a try catch to Main() that catches Exception, attempts to log it, displays an "Application has encountered an error" message and exits the application. So, my question is, does anyone see any holes in my plan? Are there any obvious exceptions that I should be catching or do these ones pretty much cover it (other than file access - I think there is only 1 place where we read-write to a config file).

  • Connection details & timeouts in a java web service client

    - by f1sh
    Hello fellow Coders, I have to implement a webservice client to a given WSDL file. I used the SDK's 'wsimport' tool to create Java classes from the WSDL as well as a class that wrap's the webservice's only method (enhanceAddress(auth, param, address)) into a simple java method. So far, so good. The webservice is functional and returning results correcty. The code looks like this: try { EnhancedAddressList uniservResponse = getWebservicePort().enhanceAddress(m_auth, m_param, uniservAddress); //Where the Port^ is the HTTP Soap 1.2 Endpoint }catch (Throwable e) { throw new AddressValidationException("Error during uniserv webservice request.", e); } The Problem now: I need to get Information about the connection and any error that might occur in order to populate various JMX values (such as COUNT_READ_TIMEOUT, COUNT_CONNECT_TIMEOUT, ...) Unfortunately, the method does not officially throw any Exceptions, so in order to get details about a ConnectException, i need to use getCause() on the ClientTransportException that will be thrown. Even worse: I tried to test the read timeout value, but there is none. I changed the service's location in the wsdl file to post the request to a php script that simply waits forever and does not return. Guess what: The web service client does not time out but waits forever as well (I killed the app after 30+ minutes of waiting). That is not an option for my application as i eventually run out of tcp connections if some of them get 'stuck'. The enhanceAddress(auth, param, address) method is not implemented but annotated with javax.jws.* Annotations, meaning that i cannot see/change/inspect the code that is actually executed. Do i have any option but to throw the whole wsimport/javax.jsw-stuff away and implement my own soap client?

  • How to modify the style of jQuery DatePicker's disabled dates?

    - by Clay
    Given this page: http://jqueryui.com/demos/datepicker/#min-max And viewing its source: http://jqueryui.com/themeroller/css/parseTheme.css.php I can change the following line (using Chrome's inspect element feature) and see those changes reflected: .ui-state-disabled, .ui-widget-content .ui-state-disabled { opacity: .35; filter:Alpha(Opacity=35); background-image: none; } However, if I try to override my own test page with something like... .ui-state-disabled, .ui-widget-content .ui-state-disabled { opacity: .99 !important; filter:Alpha(Opacity=99) !important; background-image: none !important; color:Red !important; } ...I do not see my changes reflected in the calendar. I can make other changes in my own test page and those are reflected for other classes in the datepicker. So, I'm not having any kind of path issue to the .js or .css files. What am I missing here?

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

  • Best approach to storing image pixels in bottom-up order in Java

    - by finnw
    I have an array of bytes representing an image in Windows BMP format and I would like my library to present it to the Java application as a BufferedImage, without copying the pixel data. The main problem is that all implementations of Raster in the JDK store image pixels in top-down, left-to-right order whereas BMP pixel data is stored bottom-up, left-to-right. If this is not compensated for, the resulting image will be flipped vertically. The most obvious "solution" is to set the SampleModel's scanlineStride property to a negative value and change the band offsets (or the DataBuffer's array offset) to point to the top-left pixel, i.e. the first pixel of the last line in the array. Unfortunately this does not work because all of the SampleModel constructors throw an exception if given a negative scanlineStride argument. I am currently working around it by forcing the scanlineStride field to a negative value using reflection, but I would like to do it in a cleaner and more portable way if possible. e.g. is there another way to fool the Raster or SampleModel into arranging the pixels in bottom-up order but without breaking encapsulation? Or is there a library somewhere that will wrap the Raster and SampleModel, presenting the pixel rows in reverse order? I would prefer to avoid the following approaches: Copying the whole image (for performance reasons. The code must process hundreds of large (= 1Mpixels) images per second and although the whole image must be available to the application, it will normally access only a tiny (but hard-to-predict) portion of the image.) Modifying the DataBuffer to perform coordinate transformation (this actually works but is another "dirty" solution because the buffer should not need to know about the scanline/pixel layout.) Re-implementing the Raster and/or SampleModel interfaces from scratch (but I have a hunch that I will be unable to avoid this.)

  • How to best show progress info when using ADO.NET?

    - by Yadyn
    I want to show the user detailed progress information when performing potentially lengthy database operations. Specifically, when inserting/updating data that may be on the order of hundreds of KB or MB. Currently, I'm using in-memory DataTables and DataRows which are then synced with the database via TableAdapter.Update calls. This works fine and dandy, but the single call leaves little opportunity to glean any kind of progress info to show to the user. I have no idea how much data is passing through the network to the remote DB or its progress. Basically, all I know is when Update returns and it is assumed complete (barring any errors or exceptions). But this means all I can show is 0% and then a pause and then 100%. I can count the number of rows, even going so far to cound how many are actually Modified or Added, and I could even maybe calculate per DataRow its estimated size based on the datatype of each column, using sizeof for value types like int and checking length for things like strings or byte arrays. With that, I could probably determine, before updating, an estimated total transfer size, but I'm still stuck without any progress info once Update is called on the TableAdapter. Am I stuck just using an indeterminate progress bar or mouse waiting cursor? Would I need to radically change our data access layer to be able to hook into this kind of information? Even if I can't get it down to the precise KB transferred (like a web browser file download progress bar), could I at least know when each DataRow/DataTable finishes or something? How do you best show this kind of progress info using ADO.NET?

  • How do i transfer this unmanaged code from asp to asp.net 2/mvc?

    - by melaos
    hi guys, i'm a newbie to ASP.net interop features, so what i have right here is some unmanaged dll that i need to call from my asp.net mvc app. the dll name is CTSerialNumChecksum.dll set CheckSumObj = Server.CreateObject("CTSerialNumChecksum.CRC32API") validSno = CheckSumObj.ValidateSerialNumber(no) i know it's unmanaged because when i try to add reference to the dll it doesn't work. i try to follow some tutorials on interop and marshalling but thus far i wasn't able to get the code to work. i'm trying to wrap the object into another static class and just let the rest of the app to call the code. using System; using System.Runtime.InteropServices; namespace OnlineRegisteration.Models { public static class SerialNumberChecksum { [DllImport("CTSerialNumChecksum")] public static extern int ValidateSerialNumber(string serialNo); } } Questions: How do i write the class? And what tool can i use to identify what type of dll a particular file is, i.e. unmanaged c++, etc? Also i intend to make use jquery to do ajax call later so i can use this to validate my form pre-submission. Is there a better way to handle this?

  • Database Error Handling: What if You have to Call Outside service and the Transaction Fails?

    - by Ngu Soon Hui
    We all know that we can always wrap our database call in transaction ( with or without a proper ORM), in a form like this: $con = Propel::getConnection(EventPeer::DATABASE_NAME); try { $con->begin(); // do your update, save, delete or whatever here. $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } This way would guarantee that if the transaction fails, the database is restored to the correct status. But the problem is that let's say when I do a transaction, in addition to that transaction, I need to update another database ( an example would be when I update an entry in a column in databaseA, another entry in a column in databaseB must be updated). How to handle this case? Let's say, this is my code, I have three databases that need to be updated ( dbA, dbB, dbc): $con = Propel::getConnection("dbA"); try { $con->begin(); // update to dbA // update to dbB //update to dbc $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } If dbc fails, I can rollback the dbA but I can't rollback dbb. I think this problem should be database independent. And since I am using ORM, this should be ORM independent as well. Update: Some of the database transactions are wrapped in ORM, some are using naked PDO, oledb ( or whatever bare minimum language provided database calls). So my solution has to take care this. Any idea?

  • Problem creating socket with C++ in winsock2

    - by Ash85
    Hi, I'm having the weirdest problem causing me headaches. Consider the following code: // Create and bind socket std::map<Connection, bool> clients; unsigned short port=6222; struct sockaddr_in local_address, from_address; int result; char buffer[10000]; SOCKET receive_socket; local_address.sin_family = AF_INET; local_address.sin_addr.s_addr = INADDR_ANY; local_address.sin_port = htons(port); receive_socket = socket(AF_INET,SOCK_DGRAM,0); What's happening is receive_socket is not binding, I get SOCKET_ERROR. When I debug the program and check receive_socket, it appears to just be garbled crap. I put a breakpoint on the 'std::map' line. When I step into each line of the above code, the debug cursor jumps straight from the 'unsigned short port' line to the first 'local_address.sin' line, even though I am using step into (F11), it does not stop at struct, int, char or SOCKET lines, it jumps straight over them. At this point I hover my mouse over local_address, from_address, result, buffer and receive_socket. They are all full of garbled crap. Is this because I have not defined these variables yet? I've also noticed that when I reach the bottom of the above code, local_address.sin_port is set to 19992, but it should be 6222?

  • NSUndoManager with Core Data - Redo not working

    - by CJ
    I have a Core Data document-based app which support undo/redo via the built-in NSUndoManager associated with the NSManagedObjectContext. I have a few actions set up which perform numerous tasks within Core Data, wrap all these tasks into an undo group via beginUndoGrouping/endUndoGrouping, and are processed by the NSUndoManager. Undo works fine. I can perform several successive actions, and each then undo each one of them successively and my app's state is maintained correctly. However, the "Redo" menu item is never enabled. This means that the NSUndoManager is telling the menu that there are no items to redo. I am wondering why the NSUndoManager is seemingly forgetting about items once they are undone, and not allowing redos to occur? One thing I should mention is that I'm disabling undo registration after a document is opened/created. When I perform an action, I call enableUndoRegistration, beginUndoGrouping, perform the action, then call processPendingChanges, setActionName:, endUndoGrouping, and finally disableUndoRegistration. This makes sure that only specific actions are undoable, and any other data changes I make outside of these go unnoticed to the NSUndoManager. This may be a part of the issue, but if so I'm wondering why it's affecting redo? Thanks in advance.

  • How do you update table row background color in IE using Javascript/CSS ?

    - by giulio
    I have a table that i want to "highlight" during onmouseover/onmouseout. I already know this is required in IE but not in other browsers. I have managed to detect the events triggering and this TR tag effectively works. (Note that the originating class "contentTableRow" doesn't seem to be causing any issues.) class="contentTableRow" onclick="openForm('SomeID');" onmouseover="highlight('someRowID', true);" onmouseout="highlight('someRowID', false);" id="someRowID" All is fine and dandy, the "highlight" function fires and actually sets the appropriate class. It's just that IE won't process the CSS class name change. Here is a snippet of the CSS I am using to make the change. .HighlightOn { cursor:pointer; background-color: #D1DFFF; } .HighlightOff { background-color: #E1EEFE; } I can see that the Class names are getting updated when I debug it, and also check it in Firebug. But it seems that IE doesn't like this usage of classes with a TR tag.. Is it the way I am structuring the class for Tables ? Any advice ?
