• OpenGL Wrapper in .Net

  - by Ngu Soon Hui

  This question is similar to the one here. But I feel that the answers recommended ( such as Tao and OpenTK) are not good enough because they are just a direct port from OpenGL, with no OOP design, and hard to use. What I'm looking for is a .Net OpenGL wrapper that is written in clear OOP principles, easy to use ( easy to apply textual and lighting, easy to debug etc), able to rotate the 3D diagram with mouse ( a feature that is critically missing from OpenGL and TAO), and the ability to export to other file formats ( such as dwg or dxf or Google Map file format). Any suggestion? Both Open source or commercial components would do.

• Slow SQL Sync with Microsoft Sync Framework on Mobile Client

  - by Malkier

  Hello, we are developing an application which uses MS Sync Framework to sync data between Windows CE 6.0 with SQL CE 3.5 SP1 Clients and an SQL 2008 Database. Our major problem is a slow sync time up to 1 minute for 15 tables which are totally empty. Here's a break down of our components: Server: Sql Server 2008 15 tables with activated change tracking WCF Service with endpoint for the mobile sync (uses Sync Framework 2.0) Client (Mobile) Windows CE 6.0 NET Application using Sync Framework for Devices (CTP 1) which starts the sync As I mentioned above, the sync takes up to 1 minute without any changes and empty tables. The mobile device is in its dock. This is a deal breaker for a production environment. Does anybody have any experience in this field? Is there a way to improve things? Thanks for any responses.

• Good embedded database solution (like SQLite) for .Net

  - by vfilby

  I am looking for file based storage solutions that I can use with a .Net project. THey need to have a sql-like interface for storing and retrieving data. They need to have relatively little overhead and must not require any additional components installed by the end user. I am hopping for a .dll that I can reference and use. Cool points awarded if it is closely tied to an ORM. My current favourite is SQLite, are there any better ones out there that I should know about? I have a (health?) bias against access because I feel it is overcomplicated for what I need, I am open to being convinced otherwise though. PS: "No, there is nothing better than SQLite" is a perfectly good answer.

• run .net consolapp out of a cgi script

  - by Nico

  Hello there, i have written a simple cgi python script which looks like this #!c:/Python25/python.exe -u import cgi import os def main(): print "Content-type: text/html\n" form = cgi.FieldStorage() print form["firstname"].value os.execvp("D:\\path\\to\\my\\consolapp.exe", [""]) main() As you can se i'd like to start a consoleapp which i have written in .net. But my consoleapp crashs when i call the cgi script. So i did a little debuging and write a text file after some actions i do in my .net program. The result was that my programm crash everytime i'd like to open a access mdb file. It told me that i need the Microsoft Data Access Components (MDAC). But i cant belive this message because my .net consoleapp runs without errors if i start it from my own. So can anybody give me some advise how i can call my .net consol ab through a webscript. I'm happy for every advise So it don't have to be a solution using a cgi script. Regards, Nico

• Objective-C and Android

  - by Tom R

  I've just finished a relatively large project for the Android, and it's left a bitter taste in my mouth with the knowledge that it will never run on one of the most ubiquitous handsets this side of the solar system (the one by that fruity little club). So, for my next project, I want to write it in a way that makes most of the components easily transportable between the iPhone and Android platforms. The way I'm thinking of doing this is by coding most of it in Objective-C, and then adding the platform-specific parts in more Objective-C and Java respectively. On the Android side, this will require using the the NDK. My knowledge of C is good, but my knowledge of Objective-C is close to zero, and I have no desire to learn C++. How sane is the approach above, and is there a better one? Is there any way I can code in Java and still reach the un-hacked iPhone market? And how likely is it that the people I know (iPhone users) will have an Android phone by next year?

• FLEX: is PopupManager working with mouseover / mouseout events ?

  - by Patrick

  hi, I want to make work PopupManager as a Tooltip. So I want to create a popup everytime I move the mouse over my component and make it disappear when I move the mouse out. Moreover, I have many components in my canvas, so I need it not to be too expensive. Also, when I move the mouse out from the component, but over the pop-up, it should not disappear, because I want to click on the buttons inside it. I need something similar to gmail chat popups. Is it doable with PopupManager ? thanks

• Implementing google dashboard type interface in asp.net

  - by Sam_Cogan

  I'm looking at implementing a Google IG type dashboard in a .net app. There are a number of options I've found to do this, and i'm trying to establish what is going to be the best to use, in terms of speed, versatility etc. So far the options I am looking at are either to use asp.net webparts and .net Ajax, this would make it quicker to build, but I'm concerned this is going to make the application bulky and slow, or using JQuery, and either .net MVC or Webforms, to custom build an interface. Does anyone have any thoughts on what the best option may be, or any options I may have missed? All I want to do here is to allow users to customise a dashboard with a number of components (which will be user controls). I do also have access to Telerik controls, but I'm not sure if they would be any use here.

• Is there a performance advantage in using a 64bit version of openCV+Emgu instead of 32bit?

  - by Jelly Amma

  Hello, I am developing an application that processes images captured in real time by a Point Grey camera (http://www.ptgrey.com/). The Point Grey SDK is a .net wrapper and can be either 32bit or 64bit. Then to process the captured images, I'm using a wrapper for openCV called Emgu CV (http://www.emgu.com/) that comes in both 32bit or 64bit flavors as well. Now, being on Vista64 I went for the 64bit versions of FlyCapture (Point Grey's SDK) and Emgu CV (which includes openCV in its install) hoping to maximize performance. Recently I've been wanting to call my FlyCapture+Emgu DLL code from XNA, which unfortunately only exists in 32bit, and I realize that I may have to reinstall all those components in 32bit as I don't really want to go through IPC, remoting, etc. Apart from the obvious limit to memory space inherent to 32bit, is there also a performance loss I should be expecting? How dramatic would that be and why ? Thanks in advance for any advice or explanation.

• Any good lightbox for a modal dialog?

  - by aximili

  There are thousands of lightbox components and the likes. I've looked at about 10 of them, but couldn't find what I need. Just wondering if anyone know a lightbox like component that: can popup an inline div (that is initially hidden) can be modal (eg. you must select a radio button or you can't close the box) can be called dynamically, eg. so that I can call Popup('myDiv'); on page load without the user clicking anything has sufficient documentation/examples to allow me do the above easily Thanks in advance

• Should my connected web parts support IWebPartField, IWebPartRow and IWebPartData?

  - by Javaman59

  I've been writing some simple webparts, and they communicate via a custom interface type. That's working fine. I've got one ConnectionProvider, with a variety of ConnectionConsumers. I see that the OOTB SharePoint webparts provide many standard connections, apparently through IWebPartField and IWebPartRow (IWebPartData seems less supported). I've tried to add a IWebPartRow interface to a provider, and found that it's not actually useful (apparently), unless it's shareing data that the OOTB components use, such as images, urls and users. Well, that's the impression I got, anyway... I've only done a quick experiment, and found it quite difficult to implement and test. Is there any point in spending time trying to add support for the standard webpart interfaces?

• Migrating test cases & defects from Quality Center to TFS 2008/2010

  - by stackoverflowuser

  Tool that can be used to migrate (or even better..synchronize) test cases and bugs between: TFS 2008 and Quality Center 9.2 (or later) TFS 2010 and Quality Center 9.2 (or later) I am aware of the following tools: Test Case Migrator (Excel/MHT) Tool TFS Bug Item Synchronizer 2.2 for Quality Center Also shai raiten mentions on his blog about QC 2 Team System 2010 migration tool that he has been working on and its done. But could not find any link for downloading the tool. http://blogs.microsoft.co.il/blogs/shair/archive/2009/12/31/quality-center-migration-to-team-system-2010-done.aspx Before jumping on coding with TFS SDK and QC components to come up with my own tool I need some inputs from the stackoverflow community.

• UIPickerView selectedRowInComponent: returns stale data after code adjusts it

  - by Eric Lloyd

  I have a UIPickerView with multiple components. Some values are grayed out, and my pickerView:didSelectRow:inComponent honors this by shifting the picker component in question to the nearest valid value, much as UIDatePicker moves from "30" to "28" when you select "February". Then it calls a delegate method to announce the adjusted value. When my adjuster method calls my UIPickerView's selectRow:inComponent:animated:YES, the value on screen is correct, but the values from selectedRowInComponent: are stale (from before the adjustment for gray values). However, if I call selectRow:inComponent:animated:NO, the returned values are correct, but the lack of animation is jarring. I've tried wrapping the adjustment in a beginAnimations:/commitAnimations block and catching the values in UIView's +animationDidStopSelector, but I still get stale values. Has anyone run into this before?

• Path for Delphi libraries

  - by Wouter van Nifterick

  Where do you guys store 3rd party (and your own) components? Do you keep separate copies per Delphi version? For years I've been using c:\program files\borland\delphi7\lib\, even for Delphi 2006, 2007, 2009 and 2010, like this: c:\program files\borland\delphi7\lib\AggPas\ c:\program files\borland\delphi7\lib\DeHL\ c:\program files\borland\delphi7\lib\DevExpress\ c:\program files\borland\delphi7\lib\FastCode\ c:\program files\borland\delphi7\lib\FastMM\ c:\program files\borland\delphi7\lib\Fundamentals\ c:\program files\borland\delphi7\lib\Graphics32\ c:\program files\borland\delphi7\lib\JCL\ c:\program files\borland\delphi7\lib\JVCL\ c:\program files\borland\delphi7\lib\OmniThread\ c:\program files\borland\delphi7\lib\Raize\ c:\program files\borland\delphi7\lib\TeeChartPro\ c:\program files\borland\delphi7\lib\TurboPower\ c:\program files\borland\delphi7\lib\VirtualTreeView\ c:\program files\borland\delphi7\lib\Zeos\ However, nowadays I don't even use Delphi7 anymore (what can it do that 2010 can't?), so this path doesn't make much sense anymore. I'm about to install windows7 on my home machine, so I'm thinking on something like this: c:\src\DelphiLib\ Any better ideas?

• Flex 3.5 Accordion and TabNavigator selectedIndex Bug

  - by majgis

  I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Once this behavior has been evoked, even trying to set the selectedIndex programmatically does not end in the desired result. Specifically, if set the selectedIndex to zero (or click on the first tab/header) it might temporarily hop to that index but then will finish on a different index. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

• jQueryUI Ajax.NET Postback Bug

  - by nigative

  Hi, I have this ASP.NET page with ASP.NET UpdatePanel and jQueryUI droppable and sortable components. The page works fine in all browsers, but doesn't in Internet Explorer (IE8 tested). After I try to call ASP.NET AJAX event (by pressing my asp.net button inside the UpdatePanel) my sortable list stops working properly inside IE browser and the browser throws the following error: Message: Unspecified error. Line: 145 Char: 186 Code: 0 URI: http://code.jquery.com/jquery-1.4.2.min.js I found out that the problem is caused by the code on line 66: $("#droppable").droppable(); If I comment it out, the sortable list works fine after ajax postbacks. But it doesn't make sense. Does anyone know what could be wrong? Thanks. P.S. I am using jQueryUI 1.8.1 and jQuery 1.4.2

• Sending binary data with Indy through TCP\IP, how?

  - by Wodzu

  Hello. How to send a binary data with Indy components? Which of them is most suitable for this task? I've tried to use TIdTcpClient but it allows only to send strings. I've found one reponce for that problem here but I don't get it. It says about method Write(TIdBytes), but the answer is not clear for me. Does he meant Write to some instance of TIdBytes, and how to connect that instance with TIdTcpClient? Thanks for any help.

Has anyone gone through the same experience with it ?

• Scala Actors with Java interop to underlying COM libraries

  - by wheaties

  I'm working on a JVM project which uses ESRI components (COM based, wrapped with JIntegra.) The client has requested the JAR files we produce work on the JVM and be accessible to Java code. I'd like to use Scala but I'm worried about how well the library will play with Scala's actors. Particularly I'm worried about the different mechanisms COM and Java employ to pass objects from one thread to another. Does anyone have any experience with this? Will they play nice? Edit: for clarification I noticed that when performing I/O on the ESRI DB that the CPU utilization is roughly 15%. I'd like to read each row and pass that row over to another actor for parsing. Then I could have several threads reading from the DB at once. The problem is that each row retrieved using ESRI's library is actually a Java wrapped COM object.

• Add transparent JPanel upon AWT Component to paint on

  - by Gambrinus

  Hi, I've got a Problem: In my Java application I've got an AWT Component (cannot change that one) that streams and shows an avi-file. Now I want to draw upon this movie and thought about putting a transparent JPanel above it and draw on that one. This does not work since I either see the avi-stream or the drawn lines but not both. I read somewhere that AWT does not support transparency of components - but the panel is a JPanel which is able to do so. Can someone please help me with this one - thanks in advance.

• UIWebView/MPMoviePlayerController and the "Done" button

  - by David Sowsy

  I am using the UIWebView to load both streaming audio and video. I have properly set up the UIWebView delegate and I am receiving webViewDidStartLoading and webViewFinishedLoading events perfectly. The webview launches a full screen window (likely a MPMoviePlayerController) Apple's MoviePlayer example gets the array of Windows to determine which window the moviePlayerWindow is for adding custom drawing/getting at the GUI components. I believe this to be a bad practice/hack. My expectation is that I should be able to figure out when that button was clicked by either a delegate method or an NSNotification. It may also be the case that I have to poke around subviews or controllers with isKindOf calls, but I don't think those are correct approaches. Are my expectations incorrect, and if so, why? What is the correct way to bind an action to that "Done" button?

• Introducing Ajax support in a MyFaces (JSF) + Tomahawk application

  - by Abel Morelos

  Hi, we have a project we we are using MyFaces + Tomahawk, recently I have been requested to provide enhancements to many of the existing screens by using AJAX and provide functionality such as partial refresh. As I see, Tomahawk's components don't have special support for Ajax, so it may be a lot of work to hack Tomahawk in order to use Ajax. Now, I have seen that there are other frameworks such as Trinidad, ajax4jsf, RichFaces, etc. I'm specially interested in Trinidad since it is also a MyFaces project and it has built-in Ajax support, but I'm not still convinced about Trinidad since the other frameworks also have very promising features. Considering that I have a MyFaces+Tomahawk application, what move would you suggest to take in order to introduce Ajax support? Hack with Tomahawk or directly with JSF/MyFaces? Use Trinidad? Use/Add a different framework? Thanks.
