• Transparent Background with a Modal UIViewController

  - by Mick Walker

  I have a dilema, I want to present to the user a semi-transparent view. I found out by experimenting that if I simply pushed the transparent view to the top of my NavigationController's stack, that it would not render the transparency level I wanted. So I decided to simply add the view as a subview of the current view at the top of the stack. This solution works, the view below is still visible, and the View is 'semi-modal'. The problem is, if the parent view inherits from UITableViewController (as mine does), then the view I 'push' onto it, does not cover the navigation bar at the top. I really don't want to get into a situation where I am forced to enable / disable controls on the navigation bar every time I push this view, so I was wondering, if anyone knew of any solutions that I could use so that the view I push onto the UITableViewController will actually 'push over' the navigation bar?

• Updatepanel refresh messing up JqueryUI in IE7

  - by o-logn

  Hey everyone, This is a bit of a long shot as I don't have access to the code at the moment. However, there's nothing 'special' about the code. I'm using a combination of JqueryUI and ASP.NET UpdatePanels. If I click any of the trigger controls (asp.net button), the partial-postbacks are fine. However, if I click on a trigger control after clicking on a JQueryUI button, then the entire layout messes up and a lot of the content moves upwards. I can just about reach a JQueryUI button, and when I click that, the layout returns to normal and everything's fine until I click the trigger control again. The page works fine in all latest browsers, but this problem appears in IE 7. I hope maybe someone has come across a similar problem in IE 7 and found a workaround/solution. I've been trying to fix it for a couple of days, but no luck. Thanks for any advice.

• ASP.NET GridView and UpdatePanel

  - by Echilon

  I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.

• Data import wizard library for .Net?

  - by Phil

  Does anyone know of a 3rd party data import wizard that can be embedded into applications? It should import from Excel, Access, SQLServer, csv, tab-separated flat file, XML, Oracle etc. We have a fixed data structure within our application and the user should be able to configure the wizard to match his/her import fields to our own data structure. The wizard should be a library of sorts – preferably a .Net type library. We may want to have it both web-based and desktop based (hence we may need an ASP.Net controls version and a Winforms version). We may also want integration with WPF and Silverlight. If there’s no UI wizard available, does anyone know of a non-UI library that supports easily configurable import from many, many different datasources?

• Modifying setup file with PHP

  - by Paul Lammertsma

  I have an application that needs branding when downloaded in certain continents. When installed in North America, for instance, the application, when run, displays a different logo and company name than in Europe. The setup file is provided through a PHP script. Presently there is a Inno Setup executable for Windows and a DMG for Mac OS X. I have seen that when downloading Google Chrome, you can specify whether or not it should send usage statistics. A brief look at the JavaScript that controls it reveals that this is simply sent back to the server with &usagestats=0 or &usagestats=1. How would I go about influencing the installation based upon settings specified via the PHP download page?

• When do I need to use automatic poperties and when properties with propertychanged event ?

  - by Honey

  Hello, I am using wpf and its C sharp! I have this in my Animal.cs clas private string _animalName; public string AnimalName { get { return _animalName; } set { if(_animalName!= value) { _animalName= value; this.NotifyPropertyChanged("AnimalName"); } } } I could also write: public string AnimalName {get;set;} There is no difference in binding and validation. Everythings works as before when I exchange the code. Is this due to the fact that I only create new animals but I do not allow to update the animals name in my application ? So I need to call the propertyChanged("AnimalName"); only when I want to change its property value? I am a c# beginner ;)

• Options for non-native form inputs for the web?

  - by Sam Lee

  I'm wondering if there are any good non-native form inputs for web development? I am currently using the built in <input> controls. They work just fine, but for my application they are too big (especially on OS X). I am wondering if there are any libraries that I can drop in as replacements. I am especially interested in ones that: Are a close to native control behavior as possible. Support for tabbing, highlighting current textbox, pressing up/down in <select>, etc. Have something that replicates <select> Look good and are compact I am aware that you can use CSS for some styling, but it's pretty minimal and looks different depending on the browser. Thanks for your help.

• Rough/near equivalents of Java and .NET technologies/frameworks

  - by Paul Sasik

  I work in a shop that is a mix of mostly Java and .NET technologists. When discussing new solutions and architectures we often encounter impedance in trying to compare the various technologies, frameworks, APIs etc. in use between the two camps. It seems that each camp knows little about the other and we end up comparing apples to oranges and forgetting about the bushels. While researching the topic I found this: Java -- .Net rough equivalents It's a nice list but it's not quite exhaustive and is missing the key .NET 3.0 technologies and a few other tidbits. To complete that list: what are the near/rough equivalents (or a combination of technologies) in Java to the following in .NET? WCF WPF Silverlight WF Generics Lambda expressions Linq (not Linq-to-SQL) ...have i missed anything else? Note that I omitted technologies that are already covered in the linked article. I would also like to hear feedback on whether the linked article is accurate. Thanks. (Will CW if requested.)

• InstallShield setup and Click-Once

  - by QQQ

  Hi InstallShield 10 apparently can create an installer and integrate with click once, but this feature is not active in trial version. Anyway I tried to create a click once deployment by hand (using mage) and succeed with a sample wpf application, what I want to do is click once with an installShield setup.exe file, buy it seems that it's not a .net application and I can't use it for click once. Does anyone know how installShield manages this with it's click once feature? or how can I create click once with the regular setup.exe file. Thanks.

• Event handler of Dropdownlist inside Gridview

  - by hotcoder

  I've added Dropdownlist in Gridview at RowDataBound event. The code is: if (e.Row.RowType == DataControlRowType.DataRow) { DropDownList ddlSeason = new DropDownList(); ddlSeason.DataSourceID = "odsRoomSeason"; ddlSeason.DataTextField = "SeasonTittle"; ddlSeason.DataValueField = "SeasonID"; ddlSeason.AutoPostBack = true; ddlSeason.SelectedIndexChanged += new EventHandler(ddlSeason_SelectedIndexChanged); TableCell tcSeason= new TableCell(); tcSeason.Controls.Add(ddlSeason); e.Row.Cells.AddAt(e.Row.Cells.Count, tcSeason); } The event handler I've added is: protected void ddlSeason_SelectedIndexChanged(object sender, EventArgs e) { // } But the problem is that the event handler function doesn't catch the event. Please tell me how to write the correct event handler, also I need to get the row from which the Dropdownlist's event has fired.

• WinForm Text Control that displays current character/character limit

  - by Refracted Paladin

  I need a way to display, like you see in some web apps, the current characters/character limit for a Text Control(i.e. 3/500). I usually see this as a label residing directly above or below the Text Control. How is this 'normally' accomplished? Should I override my Text Control somehow? Do I just manually add labels by every Text Control and 'bind' them to properties of the Text Control? Do I need to create a composite control that has the Text Control & Label Controls together to accomplish what I need? Any direction or help will be greatly appreciated.

• FTP in NetBeans 6.1

  - by Ross

  Is there an FTP browser hiding away in NetBeans 6.1? The help manual doesn't even suggest FTP exists. All I've been able to find so far is a tree viewer in the Services panel (no edit controls) and the ability to upload projects, folders and specific files from the Projects/Files views. Is there anywhere to delete or rename or will I have to keep switching back to my browser? I can see from the previews that there's a nice FTP controller in 6.5 but I'm not desperate enough to completely convert to a beta (yet).

• How to spin an independent dispacher thread for a Silverlight UserControl

  - by ondesertverge

  I am trying to move a lot of different elements by 1 pixel very often and in parallel. Trying to do this on one dispatcher thread means that the elements are visited one after another. The result is that the more elements I have the slower they will all move. In WPF I was able to use a HostVisual as described here to solve this. I can't seem to find anything similar in Silverlight. Is this a drawback of the lightweight framework or is there something I haven't stumbled upon yet? I am using SL4.

• Winform BindingSources - Question

  - by Stephen Patten

  I have a windows form (net 2.0) with controls on it bound to an entity (w/ INotifyPropertyChanged) through a BindingSource..works. On the same form I have a drop down list that is also wired up through a BindingSource..works Here's a sample of the relevant code: m_PlanItemLookupBindingSource.DataSource = GetBusinessLogic().RetrievePaymentPlanLookups(); // Collection of PaymentPlans paymentPlanType.Properties.DataSource = m_PlanItemLookupBindingSource; paymentPlanType.Properties.DisplayMember = "Name"; paymentPlanType.Properties.ValueMember = "ID"; paymentPlanType.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "PaymentPlanID", true, DataSourceUpdateMode.OnPropertyChanged, null, "D")); agencyComission.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "AgencyCommission", true, DataSourceUpdateMode.OnPropertyChanged, null, "P1")); billingType.DataBindings.Add(new Binding("Text", m_PlanBindingSource, "BillingType")); So when I change a value in the drop down list I thought that the m_PlanItemLookupBindingSource Current property would change along with the PaymentPlanID property of the entity which does change. Just a bit confused. Thanks in advance, Stephen

• How to change handedness of coordinates?

  - by 742

  How to convert from Euler's coordinates E1 = (x1, y1, z1, yaw1, pitch1, roll1) to E2 = (x2, y2, z2, yaw2, pitch2, roll2) where x, y, z are the coordinates of a point and yaw, pitch, roll the direction/orientation of a vector which origin is the point. yaw is around y, pitch around x, roll around z. They are performed in that order. Yaw 0 is normal to the plan xy (opposite to z in E1 and equal to z in E2). E1 uses a right handed space and E2 a left handed space. Both have the same origin, the same direction for y (top) and z (into the screen). They differ by x which is to the left on E1 and to the right on E2. They also differ by their direction of positive rotations. I've a custom type to hold the scalar representation and to convert from and to the equivalent WPF Matrix3d representation.

• How to programmatically determine name of CKEditor instance

  - by ChrisA

  I've added a CKEditor instance programmatically to my page in the code-behind of my ASP.NET page: VB.NET: itemEditor = New CkEditor cell.Controls.Add(itemEditor) ... which works fine. I can get the HTML on the postback and do stuff with it. However, I also want to do some client-side stuff with it, specifically take a selected item out of another control, and insert it into the text by handling the onchange event. So, how can I get the name of the editor instance in the JavaScript, so that I can do stuff like: function GetCkText() { var htmlFromEditor = CKEDITOR.instances['editorName'].getData(); // do stuff with htmlFromEditor }

• Auto scrolling or shifting a bitmap in .NET

  - by mikej

  I have a .NET GDI+ bitmap object (or if it makes the problem easier a WPF bitmap object) and what I want to to is shift the whole lot by dx,dy (whole pixels) and I would ideally like to do it using .NET but API calls are ok. It has to be efficient bacause its going to be called 10,000 times say with moderately large bitmaps. I have implemented a solution using DrawImage - but its slow and it halts the application for minutes while the GC cleans up the temp objects that have been used. I have also started to work on a version using ScrollDC but so far have had no luck getting it to work on the DC of the bitmap (I can make it work buy creating an API bitmap with bitmap handle, then creating a compatible DC asnd calling ScrollDC but then I have to put it back into the bitmap object). There has to be an "inplace" way of shifting a bitmap. mikej

• How to disable listbox's click event

  - by StupidDeveloper

  I have a listbox which acts as a list of items. If you click on some item, it's contents are shown in the panel on the right (few textboxes etc.). I need to have a validation on these controls as all of them are required fields. And I do have it. The problem is that, even when the validators are not valid, user can click the listbox and change active index (that doesn't have impact on the panel on the right, as SelectedIndexChanged isn't fired). The validators are standard RequiredFieldValidator with their Display property set to "Dynamic". So, what I want is to disallow the user clicking on the listbox and changing the index untill all validators are Valid. What would be your solution for that? Is that even possible?

• Show different sub-sets in edit view

  - by Martin R-L

  In the context of C# 4, ASP.NET MVC 2, and NHibernate; I've got the following scenario: Let's assume an entity Product that have an association to ProductType. In a product edit view; how do I implement that only a sub-set of the product's properties are shown in an elegant and DRY way? Use a product view model builder, and from different view models automagically generate the view with my own Html.EditorForModel() (including drop-downs and other stuff not out-of-the-box)? Attribute the properties of one view model and use the Html.EditorForModel() way aforementioned? Use one model, but implement different web controls (view strategies) (can it be done DRY?)? Something else entirely?

• Jabber .net rostertree error

  - by Farooq

  Hi, Whenever I add the rostertree control to my form, I can see that the PresenceManager and RosterManager property values for it have this error listed: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.ComponentModel.Component'." I can compile the solution and all but this error keeps popping up randomly. Can someone advice when this may happen. I'm thinking it has to do with the controls not being added properly. I'm using Visual Studio 2008. Thanks.

• rdlc - phantom page break, what to check?

  - by Antonio Nakic Alfirevic

  I have a RDLC report which has some controls on the first page, which are inside a rectangle and which display ok. Beneath the rectangle, i have a matrix, which spans more than one page both in width and in height. I want the matrix to start rendering on the second page. If I enable "insert break before" on the matrix, there is an extra blank page before the matrix(in print layout), which is my problem. If I reduce the amount of data, so the matrix does not span more than one page in width, there is no blank page, and all is well. I checked the Page and Body sizes, they are ok. Any tips? This has been driving me crazy all day, what can I check? Thx

• Is it feasible to write a Firefox plugin to make use of ActiveX control on Windows?

  - by Gary B2312321321

  I use an ActiveX control called TAPIEx enabling TAPI phone system integration using MS Access 2000 (+Visual Basic). I want to turn this Access database into a web app with the clients running Firefox (all on internal network). Since Firefox doesnt support ActiveX is it feasible for me to write a Firefox plugin that in turn utilizes the ActiveX control? With regard to how plugins work - Would I be able to call 'functions' of the plugin from page script (eg dial call specifying phone number, check if calls in process)? Would adding these functions to the Firefox right click menu 'globally' inside Firefox be easier? Hope you guys can help. Note I'm not a fulltime programmer; I just need to know how steep the learning curve will be or even if my idea is possible! Ive now found a project to allow using activex controls in firefox that seems to be quite up to date at: http://code.google.com/p/ff-activex-host/
