• [WPF] selected item in listbox unreadable because of the color !

  - by Anna

  I dynamically create a collection of stackpanels in my listbox. In this stackpanel are contained labels and checkbox horizontally aligned. The problem is when I click on a stackpanel, the selection is unreadable because the line become dark-blue whereas the letters stay black so black on blue, you see nothing... how can I dynamically change the forecolor of the selected elements in the stackpanel ? I say dynamically and not in the xml file, because all those elements are dynamically created, base on a database... thanksssss!!

• Trying to speed up a SQLITE UNION QUERY

  - by user142683

  I have the below SQLITE code SELECT x.t, CASE WHEN S.Status='A' AND M.Nomorebets=0 THEN S.PriceText ELSE '-' END AS Show_Price FROM sb_Market M LEFT OUTER JOIN (select 2010 t union select 2020 t union select 2030 t union select 2040 t union select 2050 t union select 2060 t union select 2070 t ) as x LEFT OUTER JOIN sb_Selection S ON S.MeetingId=M.MeetingId AND S.EventId=M.EventId AND S.MarketId=M.MarketId AND x.t=S.team WHERE M.meetingid=8051 AND M.eventid=3 AND M.Name='Correct Score' With the current interface restrictions, I have to use the above code to ensure that if one selection is missing, that a '-' appears. Some feed would be something like the following SelectionId Name Team Status PriceText =================================== 1 Barney 2010 A 10 2 Jim 2020 A 5 3 Matt 2030 A 6 4 John 2040 A 8 5 Paul 2050 A 15/2 6 Frank 2060 S 10/11 7 Tom 2070 A 15 Is using the above SQL code the quickest & efficient?? Please advise of anything that could help. Messages with updates would be preferable.

• jList in Scrollpane, seeking and displaying value of selectedIndex

  - by Mech Software

  I have a JList inside a Scrollpane. If you click on the list and move the arrow keys up and down it works like you expect, you can move your selection index and display around just fine. Now, what I want to do is basically have a text box and i'm typing in the text box like "comic" and want it to seek to the index of that value. This WORKS just fine. Where the problem is when the value of the list box is below, or above the viewable area. When it is, the selected index seeks, but does not change the position of the scrollable region. However, if I press the up or down arrows and requestFocus() to the list, and move up and down it seeks to the right viewable area. What am I missing to make this happen WITHOUT changing focus. I want to be able to just type in the list all I want and have it show me what is selected. I feel i'm missing something obvious here.

• Embedded Prolog Interpreter/Compiler for Java

  - by Sami

  I'm working on an application in Java, that needs to do some complex logic rule deductions as part of its functionality. I'd like to code my logic deductions in Prolog or some other logic/constraint programming language, instead of Java, as I believe the resulting code will be significantly simpler and more maintainable. I Googled for embedded Java implementations on Prolog, and found number of them, each with very little documentation. My (modest) selection criteria are: should be embeddable in Java (e.g. can be bundled up with my java package instead of requiring any native installations on external programs) simple interface to use from Java (for initiating deductions, inspecting results, and adding rules) come with at least a few examples on how to use it doesn't necessarely have to be Prolog, but other logic/constraint programming languages with the above criteria would suit my needs, too. What choices do I have and what are their advantages and disadvantages?

• grouping draggable objects with jquery-ui draggable

  - by Jim Robert

  Hello, I want to use jquery draggable/droppable to let the user select a group of objects (each one has a checkbox in the corner) and then drag all the selected objects as a group... I can't figure out for the life of me how to do it haha. Here is what I'm thinking will lead to a usable solution, on each draggable object, use the start() event and somehow grab all the other selected objects and add them to the selection I was also considering just making the dragged object look like a group of objects (they're images, so a pile of photos maybe) for performance reasons. I think using the draggable functionality might fall over if you drag several dozen objects at once, does that sound like a better idea?

• Examples of good IDEs to analyze for custom Form/Report designer

  - by Paul Sasik

  I am working on a basic form/report designer. Some of the features i'm looking to implement are: Single or multiple selection of objects Alignment of objects (when several are selected) Same-sizing of objects (when several are selected) Moving/dragging of selected object(s) Selected object resizing in eight directions (using object grips) For features and look-and-feel I've analyzed and used a mixture of ideas from: MS Visual Studio 200x (most useful so far) Visio Crystal Reports My question is: Have I overlooked some other IDEs that provide these kinds of features that are better and user-friendlier examples of what to do than others i've looked at? (They don't have to be Microsoft products. That's just what i have ready access to.)

• Outline view from UITableView

  - by Raj

  Hi guys, I need to implement a 1 level outline view out of UITableView. The cells which have children in them will have a '+' symbol and if user taps on it, the cells below it should slide down and the children cells of current selected row should appear. The sliding of cells should be visible and if the user taps '-' button of the already expanded row, the children cells should slide back into the parent. I have tried googling but did not find any pointers. How should I start, should I subclass UITableView? Or should I implement my own view sub-class and handle all the stuff there? I somehow feel it would be easier to sub-class UITableView because it will handle all the row selection for us, but I cannot figure out how to do it. Thanks and Regards, Raj

• Opening popup links in UIWebView, possible?

  - by Jasarien

  Hey guys, I have a UIWebView which I'm using as an embedded browser within my app. I've noticed that links in webpages that open new windows are ignored without any call into my code. I've tried breakpointing on - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType and then selecting a link that would open a popup window, and the breakpoint is never hit. Is there anything I can do to intercept that selection of the popup link and get the URL and just load it normally? I'm not interested in displaying a popup window in the app itself, I just want the URL of whatever is going to be loaded in the popup window to load in the main webview itself. Is this possible? Thanks!

• click feature in Qt

  - by Solitaire

  Hi, I just want to clarify, weather the feature is present or not in Qt. The scenario is like this, I have a list view with items, I want to place the icon to the listview when the item is selected. The selection I mean is, first time when I click item should be selected, next time if I click the same item then it should be selected. Please note It is not the double click. So is there any feature which handles this feature by default, any property or flag which I need to set to listview to behave like this or manual implementation Is required for this.

• Installing a new SQL Server instance fails

  - by Rubio

  I've previously in my setup installed SQL Server Express 2005. Now I've switched to SQL Server Express 2008. I updated the command line parameters to those documented for the latter. If the comp already has SQL Server Express 2008 installed, my installer should create a new instance. The command line parameters are as follows: /ACTION=Install /FEATURES=SQLEngine /QS /INSTANCENAME=ABCD /SECURITYMODE=SQL /SAPWD=CunningPassword The requested instance name does not exist on the target machine. This will end in an error -2068643838. The logs show the following error: "No features were installed during the setup execution. The requested features may already be installed." If I remove the /QS parameter and try to install interactively, I'll get as far as the Feature Selection page. The UI shows three options, Instance Features, Shared Features and Redistributable Features. Whatever I select, clicking Next results in the same error (There are validation errors on this page). Any ideas anyone? Thanks, -- Rubio

• LabVIEW: converting numeric array to string array

  - by JaysonFix

  Using LabVIEW 2009, I have a VI that outputs an array of U64 integers. I'd like the user to be able to perform discrete selection from among the elements of this array. I'm thinking of accomplishing this by programmatically populating a Menu Ring (as shown at http://digital.ni.com/public.nsf/allkb/FB0409491FAB16FA86256D08004FCE7E). However, I apparently need to convert my array of U64 ints to an array of strings, as it is an array of strings that is used to populate the Menu Ring. My question: how can I convert the array of U64 ints to an array of strings?

• Core Data Image Won't Load Into NSTableView Image Cell

  - by jcady

  In my code I am storing an image into my Core Data model (works fine). If I set up my view to have an NSImageView and bind its Data to Controller Key: selection and modelKeyPath: myImagePath, it works. It will show each image for the selected row. I then create a new column in my NSTableView and drag an image cell onto the column. However, I cannot get my Core Data bindings to have the image show up in the cell. I have tried binding both value and data, but no luck. Since I am sure the image is stored properly, what am I doing wrong in my binding to prevent the image from showing up in the table cell? Thanks so much. (My background: new Cocoa developer who has recently gone through the entire Hillegass book.)

• Visual Studio - "attach to particular instance of the process" macro

  - by Steve

  I guess prety much everyone who does a lot of debugging have a handy macro in Visual Studio (with shortcut to it on a toolbar) which when called automatically attaches to a particular process (identified by name). it saves a lot of time rather than clicking "Debug" - "Attach to the process ...", but it only works if one is running a single instance of the process one wants to attach to. If theres is more than one instance of particular process in memory - the first one (with a smaller PID?) is being choose by debugger. Does anyone have a macro which shows a dialog (if more that 1 process with a specified name running) and lets developer to select to one he/she really wants to attach to. I guess the selection could be made based on a windwow caption text (which would be suffice in most of cases) and when the particular instance is selected macro passes the PID of the process to the Debugger object? If someone has that macro or knows how to write it - please share. Thanks.

• iPhone development: Best method to allow user to chose search scope

  - by Mark Pemburn

  Hi, I'm developing my first iPhone app and want to allow the user to select the scope of their search in a more complex way than the 'scope buttons' permit. The app is related to wines and I want to the user to be able to select the 'color' (Red, White, Blush, etc.) first, and then select the type/varietal within that category. Right now, I'm using the UISearchBar's scope buttons for the colors and tapping the button opens a view with the selection of colors. This is okay except that once the 'Red' button has been selected, I can't select it a second time to change my choice of type (e.g., change from 'Merlot' to 'Syrrah', etc.) If there's a better way to do this, I'm willing to scrap my method and start from scratch. Thanks!

• Word 2007 Question

  - by Lijo

  Hi Team, While preparing a Word 2007 document, I made a mistake. (Not to say I don't have any other copy of the document) While formatting (as a try) I applied the style "Apply Style to Body to match selection". This caused the document to go totally in a wronfg format - having numbers even in tables. Have you ever faced this? Could you please tell how to correct it? Hope you would be kind enough to answer this even though it is not striclty technical. Thanks Lijo

• Manage Foreign key and Drop downlist for optional field in .NET

  - by Brij

  What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

How would i go about this? Cheers.

• Generic Text Only printer driver mangles control codes

  - by Terry

  If an escape character (or most other characters < 0x20) is sent to the generic / text only printer it gets printed as a period. Using the code in the WinDDK is it possible to 'correct' this behaviour so that it passes it through unmodified? The general scenario for this is that some application ('user app') outputs a document to a windows printer. My application requires this data in plain text form and so what I do is run a generic / text only printer that talks to a virtual com port. This generally works fine except where the 'user app' outputs binary data to the print queue without using the correct mechanism (which seems to work fine on some printer drivers, such as the Epson POS ones, but not the generic / text only one). I've tried changing the print processor selection without success and also tried looking at the gtt files to see if I could readily map in these characters as though they were printable, but the minidriver tool won't let me do that. Any suggestions?

• Oracle Apex:Why is this dynamic action not getting triggered/fired ?

  - by Sathya

  I'm using Application Express 4.0.0.00.25 ( Apex 4.0 EA2 ). I've created a tabular form, with few fields. Each of the field are not direct entry, but rather a LOV picker is attached to these, and on selecting the LOV value, the id gets stored in the field. I have a dynamic action associated to the field, ( event - change in item, condition - always, action - Set value via SQL query ). However, on selecting the value from the LOV, the dynamic action doesn't get triggered. If I select the dynamic action to be fired on page load, then it works but not upon selection of an item from the LOV. Why is this so, is it by design or a bug ?

This view will have a single row selection and a button to delete, edit the current selected row in a popup Form and a insert button that will use the same Form as well.

After the event I get the row that was selected before. Other thing I dont understand yet in C# how to have a single recordSet and know wich is the current record even if its a new being inserted in a way that once in the Form all data being entered will show up at the same time in the DataGridView.
