• fixed vertical positioning of css within an iframe

  - by Jake Rider

  I am trying to get my bottom header to stick to the bottom of the screen inside of my iframe application and have it always appear in view for the user even when the page is scrolling. I have no control over the outer iframe as it is on a different domain. The header itself must be inside of the iframe as I have no control outside the iframe. The iframe always expands to the height of its contents so that it has no scrollbars, but the bar still has to be visible in the viewport at all times.

• Getting Started on Isometric Board Game port

  - by Jehosephat

  I have developed a (off-line) board game that I would like to translate to an online/social game in an isometric grid perspective. My background is in .NET web development, so I'm very comfortable with C#, HTML, jQuery/javascript. Still getting my feet wet with HTML5. I have familiarity with Flash, but I haven't worked with it in years. I'm also interested in working with Azure for hosting the back-end. Ultimately I'd like this game to have persistent leaderboard/achievements and therefore be able to log in through FB and Kong and the like. Obviously, I'm not looking for 'here's exactly how to do all of this'. But I would love some opinions on where to start, particularly given my background and goals. Would be happy to share more details if it makes answering easier! Thanks!

• How to set width of textbox to be same as MaxLength in ASP.NET

  - by John Galt

  Is there a way I can limit the width of a textbox to be equal to the MaxLength property? In my case right now, the textbox control is placed in a table cell as in this snippet: <td class=TDSmallerBold style="width:90%"> <asp:textbox id="txtTitle" runat="server" CausesValidation="true" Text="Type a title here..be concise but descriptive. Include price." ToolTip="Describe the item with a short pithy title (most important keywords first). Include the price. The title you provide here will be the primary text found by search engines that index Zipeee content." MaxLength="60" Width="100%"> </asp:textbox> (I know I should not use HTML tables to control layout..another subject for sure) but is there a way to constrain the actual width to the max number of characters allowed in the typed box?

• Deformation of Sphere using Transformations

  - by Mert Toka

  I have a graphic related question. I need to have a transformation matrix that I have no idea about what it is. The problem is to create right image from the right sphere. I created those images in Maya, but I need some matrices for the graphics course. Here is the image: Our professor told us to use some sine and cosine in our transformations, but I have no idea what he meant. I thought of intersecting a plane from the grid(that is xz plane) and sphere, and then scaling down the resulting circle. Would that work? I also checked this paper, however it looks like a bit advanced for me. Another thing is I guess that paper is not about the same type of information I was looking for. It would be great if you could help me.

• My map callouts don't display the image when clicked

  - by Neelam Khan

  I am developing an iPhone application for a university project and I'm new to iPhone development. I have looked through Apple's MapCallouts code but it doesn't seem feasible to implement it. So far my code displays a map, drops annotations, displays the title and it displays the right call out button. But this is where I encounter problems. When I press on the callout button, it displays a blank view controller but it should display a different image for every callout that's tapped and this isn't happening so far. I have added my code below: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { //NSUInteger tag = ((UIButton *)control).tag; if (self.detailController==nil) { DetailViewController* detailViewController = [[DetailViewController alloc] init]; [self.navigationController pushViewController:detailViewController animated:YES]; } // self.detailController.tag =1; //to identify image required // self.detailController.tag = tag; [self.navigationController pushViewController:detailController animated:YES]; }

• ServerControl randomly null

  - by Sascha

  Hi, I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment. Anyone an idea how to find more info to find what's happening? Or has someone had a similar error? Thanks. sa

• Providing help documentation in VB.NET?

  - by blerh

  I have written up troubleshooting documents for my project and would like them included in my program. I remember in VB6 there was a very easy way to do this with a control, where it already has the help document tree set up on the left and you just set it to point to certain files. Does something like this exist for .NET? I am aware of the HelpProvider control but as far as I know this just puts in tooltips and opens documents on a button press? Thanks for any help. :)

• Strange tab ordering when creating controls after postback

  - by Crackerjack

  I have a button that opens a panel in a popup window and then performs a postback to retrieve data from the server and render some controls. Some of the controls are textboxes and some are dropdown lists and can be in any order. Everything works fine when tabbing through the textbox controls. But when tabbing from the first dropdown contorl found, the tab order 'gets lost' and it starts tabbing from the first control again. When I tab to the same dropdown list the second time 'round, it correctly tabs to the next control. Does anyone know what might be going on? Example: TextBox1 (Tab -> focus set to 'TextBox2') TextBox2 (Tab -> focus set to 'DropDown1') DropDown1 (Tab -> focus goes back up to 'TextBox1' - wtf?) TextBox3 Update: The TabIndex attribute is set on all controls.

• Is there a way to put Setter elements inside EventTrigger?

  - by Dennis Delimarsky

  Working on a WPF application, I started working on a custom ControlTemplate. I reached the point where I need to change some control properties when an event occurs. For this purpose, there are Setter elements. Seems all good, but I cannot use them inside EventTrigger elements. For example, if a simple Trigger, that can be bound to control properties, is used then Setter elements can be used inside. However, I do not want to bind to a property change but rather to an event. Is there a way to do this in pure XAML or will I have to work in the code-behind?

• Difference between Popup's IsOpen and Visibility properties?

  - by cfouche

  I've played around with the WPF Popup Control and as far as I can see, the Visibility property is superfluous. If you have a Popup with IsOpen = True, it will be visible even if its Visibility = Collapsed. If you have a Popup with IsOpen = False, then its Visibility will be Collapsed, and will remain "Collapsed" when IsOpen changes to true, and it will appear. (i.e. you'll have something that appears on your screen, even though Snoop says it is Collapsed.) Why does the Popup control have both these properties? Am I missing something here?

• "Initializing - Busy - Stopping" LOOP issue in Azure deployement

  - by Kushal Waikar

  Hi folks, I am trying to deploy an azure cloud application on Windows Azure. Application specifications are -- It has one WebRole - ASP.Net MVC Application (ASP.Net charting control is used in this MVC application) It does not contain any worker role. Third party references are set with property "copy Local" to "true"(MVC,ASP Charting control & ASP Provider DLLs) There is no DiagnosticsConnectionString in service configuration file It uses ASP provider for session state management. This application runs successfully on local dev fabric but when I try to deploy it on Windows Azure it gets stuck in a loop with status being changed between Initializing, Busy, Stopping states. It never goes into READY state. It seems that there are no ERROR logs for conveying the deployment issues to user. So is there any way to diagnose deployment issues ? Is there any way to get deployment ERROR logs ? Any kind of help will be appreciated. Thanks, Kushal

• VS2010 Publish Profiles -- Where are they stored?

  - by Jeff S

  We have set up a few Publish Profiles that are used to deploy web apps to various servers, and it all works great with 1-click deployment. However, w find that even though the entire solution is under source control (svn), the profiles do not seem to be carried over, so we need to re-create the profiles on each developer's machine manually. It seems, since the profiles only exist for the solution currently loaded, that they must be stored in the solution files somewhere, but they do not carry over when someone else does an update to pull down the code. I'm guessing whatever file they're in is one we aren' covering in the source control project, but I haven't been able to figure out which one. Someone must know where the Publish Profiles are stored -- is there any way to copy them from machine to machine so we don't have to retype them for each developer?

• HTTP caching confusion

  - by Keith

  I'm not sure whether this is a server issue, or whether I'm failing to understand how HTTP caching really works. I have an ASP MVC application running on IIS7. There's a lot of static content as part of the site including lots of CSS, Javascript and image files. For these files I want the browser to cache them for at least a day - our .css, .js, .gif and .png files rarely change. My web.config goes like this: <system.webServer> <staticContent> <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" /> </staticContent> </system.webServer> The problem I'm getting is that the browser (tested Chrome, IE8 and FX) doesn't seem to be caching the files as I'd expect. I've got the default settings (check for newer pages automatically in IE). On first visit the content downloads as expected HTTP/1.1 200 OK Cache-Control: max-age=86400 Content-Type: image/gif Last-Modified: Fri, 07 Aug 2009 09:55:15 GMT Accept-Ranges: bytes ETag: "3efeb2294517ca1:0" Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET Date: Mon, 07 Jun 2010 14:29:16 GMT Content-Length: 918 <content> I think that the Cache-Control: max-age=86400 should tell the browser not to request the page again for a day. Ok, so now the page is reloaded and the browser requests the image again. This time it gets an empty response with these headers: HTTP/1.1 304 Not Modified Cache-Control: max-age=86400 Last-Modified: Fri, 07 Aug 2009 09:55:15 GMT Accept-Ranges: bytes ETag: "3efeb2294517ca1:0" Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET Date: Mon, 07 Jun 2010 14:30:32 GMT So it looks like the browser has sent the ETag back (as a unique id for the resource), and the server's come back with a 304 Not Modified - telling the browser that it can use the previously downloaded file. It seems to me that would be correct for many caching situations, but here I don't want the extra round trip. I don't care if the image gets out of date when the file on the server changes. There are a lot of these files (even with sprite-maps and the like) and many of our clients have very slow networks. Each round trip to ping for that 304 status is taking about a 10th to a 5th of a second. Many also have IE6 which only has 2 HTTP connections at a time. The net result is that our application appears to be very slow for these clients with every page taking an extra couple of seconds to check that the static content hasn't changed. What response header am I missing that would cause the browser to aggressively cache the files? How would I set this in a .Net web.config for IIS7? Am I misunderstanding how HTTP caching works in the first place?

• How to disable the auto resizing of Windows when you touch the top or bottom

  - by L. D. James

  Can someone tell me how to stop the autoresizing behavior of Windows in Ubuntu 14.04 when you touch the top or bottom when resizing the window. There is an undesirable effect of the the bottom resizing all the way to the bottom when you only want to resize the top, or vice-versa. In the past it was possible to disable this effect by unchecking grid in CCSM. Then came Unity Tweak tool which made it easy to remove. You could remove it by turning off Window snapping and Hotcorners. Now in Ubuntu 14.04 I have all those feature turned off and yet I can't resize only the top or only the bottom without the other end automatically moving.

• Context module for block visibility

  - by calebthorne

  I have a site built in Drupal 6 that requires a number of blocks that are only visible to certain roles or on specific pages. Normally, I would use the block configuration settings to control page and role visibility. However I recently ran across the context module that effectively splits the site into "sections" or "groups" of related attributes. My question is: When is it appropriate to control block visibility from context rather than the block configuration settings? Should I only use one or the other or a combination of both?

• Square game map rendered as sphere

  - by Roflha

  For a hobby project of mine I have created a finite voxel world (similar to Minecraft), but as I said, mine is finite. When you reach the edge of it, you are sent to the other side. That is all working fine along with rendering the far side of the map, but I want to be able to render this grid as a sphere. Looking down from above, the world is a square. I basically want to be able to represent a portion of that square as a sphere, as if you were looking at a planet. Right now I am experimenting with taking a circular section of the map, and rendering that, but it look to flat (no curvature around the edges). My question then, is what would be the best way to add some curvature to the edges of a 2d circle to make it look like a hemisphere. However, I am not overly attached to this implementation so if somebody has some other idea for representing the square as a planet, I am all ears.

• .NET ORM and Security

  - by Sphynx

  We're going to use an ORM tool with a .NET desktop application. The tool allows creation of persistent classes. It generates all database tables automatically. In addition to other data, our system needs to store user credentials, and deliver access control. The question is, is there any possibility of access control by means of ORM, without creating the database authentication mechanisms manually? Is there any product on the market which allows this? We thought of limiting the access in the program itself, but users can easily access the database directly, and bypass the program limitations. Thanks.
