• WF - Creating a selective list

  - by Michael Bendtsen

  I have a stupid question. I have created a workflow Designer host where I publish my own activities. I also have a property grid which only displays the properties decorated with a special attribute. This designer is going to be used by none IT staff. What I want is that on an activity the user can select a property value from a list. I know I just could create an Enum but I would like it to be dynamic. I.e. all events on a specific interface (extracted using reflection). Is this at all possible or am I stuck with enums?

  - by Jack

  Hi, I am creating a Rails app and have added a form: <div class="field"> <%= f.label :title %><br /> <%= f.text_field :title %> </div> <div class="field"> <%= f.label :client_id %><br /> <%= collection_select(:project, :client_id, Client.all, :id, :contact_name, {:prompt => "Select a Client"}) %> </div> This currently displays the contact_name of the client.

• Is there a way to be notified when the user makes changes in a wxStyledTextCtrl?

  - by George Edison

  I have a wxWidgets application that has a wxStyledTextCtrl. But for the life of me, I cannot figure out how to get notified of modification events. I have the following code: void CMainWindow::OnDocumentModified(wxStyledTextEvent & event) { wxString msg; msg << event.GetModificationType(); wxMessageBox(msg); } This gets called for EVT_STC_MODIFIED. When I run the application and press a key, the message box displays 1040 and 8209. When I call SetText the same two messages are displayed. How can I differentiate between user events and programmatically-generated events?

• How to change the size of NSImageView control from within program?

  - by Adam

  The following line of code displays an image on my application window, within an NSImageView control named outputImageView. I used Interface Builder to put the NSImageView control onto the window, initially (then bound it to outputImageView). How do I change the size of the NSImageView control within my program, so that it matches the size of the actual image I am displaying (which may change, periodically)? And what if I wanted to change the anchor point for the image (i.e., centered, left edge, bottom right, or whatever? Thanks in advance! [outputImageView setImage: outputImage];

• Problems with viewing site in Internet Exploder

  - by Kevin

  I built a site and I'm just about finished. It displays properly in all the browsers I have (Safari, Chrome, and Firefox) but my client is not computer savvy at all and still uses Internet Explorer, so that's all he's using to view the site. I don't have IE to test the site so I've been using BrowserStack.com and I see in IE that the site is broken. The navigation bar has a white background and is pushed down a line, and the logo isn't appearing. Could anybody please assist me with figuring out why the site isn't displaying properly in IE, and how to fix it? Help is greatly appreciated. Thanks Site: WebuildCAhomes dot com

• How to build a LINQ query from text at runtime?

  - by Danvil

  I have a class A { public int X; public double Y; public string Z; // and more fields/properties ... }; and a List<A> data and can build a linq query like e.g. var q = from a in data where a.X > 20 select new {a.Y, a.Z}; Then dataGridView1.DataSource = q.ToList(); displays the selection in my DataGridView. Now the question, is it possible to build the query from a text the user has entered at runtime? Like var q = QueryFromText("from a in data where a.X > 20 select new {a.Y, a.Z}"); The point being, that the user (having programming skills) can dynamically and freely select the displayed data.

  I am having a really annoying bug, which yet I don't know how to trace it. I have an activity with 3 tabs, each populated by adapters build by asynctasks. They are displaying well, navigation is fine. I've extended TabActivity. But whenever I hit the Back/Menu/Search button it halts, then after a while the OS displays me this warning: Sorry Activity Contacts (in application MyApp) is not responding. Force close or Wait. How can I trace this problem on the phone?

• Android Contact Picker

  - by user1066398

  I was wondering: Is it possible to customize the Android Contact Picker so that it can also allow adding a new contact as a menu option in the default contact list? At the moment, if I invoke the contact picker from my activity, it only displays the default contact list. I would also like the user to be able to create a new contact if it did not exist already. I have searched this quite a lot but do not find appropriate API to do this. There is nothing in ContactContract as far as I can see.

• What is the correct way to customize Icon and Text position of items in a QListView?

  - by petermcg

  I'm using C++ and Qt's (4.6) model/view framework and wondering what is the correct way to change the display of items in a QListView or a class derived from QListView from: to: I'm not concerned about the sort order or Flow, I'm interested in the best way to correctly position the text to the right of the icon. If this can only be done by writing a custom QStyledItemDelegate that's totally fine, I want to rule out whether this is the correct approach or whether it's best to look at setLayout or similar, example code would help. The example application I'm looking at is the 'interview' example from qtdemo which amongst other things displays icons and text in a QListView.

• Setting Frame.Content doesn't always work

  - by dan gibson

  I have a Frame control and I'm setting the Content property. If I set it twice, first to one control then to another, it shows the first control instead of the second. If I display a message box after setting it the first time then it works fine (ie it displays the second control). It's like I can only set Content once until the screen has been repainted. Calling Frame.UpdateLayout also doesn't help. What should I call after setting Content so that I can be sure that Content is actually set to what I specify?

• Swing: Programmatically select a text

  - by HH

  Hey everyone, I have a very simple Swing GUI with just a JTetxtArea. I am trying to programmatically select a part of text using: textArea.select(startSelection,endSelection); This work. However as soon as I add some other components to the GUI I do not see selection anymore frame.getContentPane().add(button); frame.getContentPane().add(textArea); textArea.select(startSelection,endSelection); I suspect that during layouting the gui, some event causes the text to be deselected. Am I right? And could anybody suggest a solution? My goal is to have a program which displays a text, and allows the user to input start and end selection position, and a selection appears between these two position. Thank you.

  var spaces="----"; var category_name="category"; var category_text=spaces+category_name; alert(category_text); $('select').append($("<option>").attr({'value' : inserted_id , 'label' : category_name}).text(category_text)); This code includes option to my listbox. The problem in Internet Explorer 7. The option is included, but the expected display is '----category'. But Internet Explorer 7 displays only category in options. Since I am using tree order I need to have hyphens before some category. How can I solve it in Internet Explorer 7?

• how to avoid storing several times a repeated field of a Symfony form?

  - by user454760

  Hello everybody, I am working with Symfony 1.4 and Doctrine. I have a model A with an email field. The form of A displays an input in which the user should insert the email correctly. But as everybody knows, sometimes they don't do it. To fix this I have inserted an extra field in the model (and in the form), called *repeat_email* to prevent the misspellings. Then, in the validation process, after validating all the fields, i use a global validator to compare the data of the two fields. This works, but I don't want to have the email stored two times in the database (I don't want the *repeat_email*). Is there any mechanism to use it in the validation process, but not to store it in the database? Thanks,

• which one consume less resources? opening text file or make an sql query,both a thousand times ?

  - by imin

  hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

• sorting extendeddatatable in richfaces

  - by user414597

  Hello All, does anyone know how exactly the default sorting works in richfaces datatable columns? (using sortby) My problem is that once a sort has been performed, the new data order is never preserved in my backing's bean data model (which makes me wonder where is this new order now stored?), that is the actual datamodel always contains just the original data.. So if say user goes to a another page and returns to what should be sorted data (using back button) , the data displays as original, not sorted.. Has anyone come across this? also, is there a way to do server side sorting, i.e. call my own sort method upon clicking the header..? many thanks for any advice!

• Accessing loop iteration in a sub-function?

  - by DisgruntledGoat

  I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?
