  • Error details in embedded IronPython

    - by Achim
    Hi, I'm executing IronPython in my application. A script produces an UnboundNameException with the message "name 'source' is not defined". Because the script is correct in my opinion I would need more error information, but I'm not able to get them from the exception. The exception itself seems not to contain any information about line number of the source of the exception or something like this. I searched on Google, but all available information seems to be outdated. The Data dictionary of my exception is empty which means that Data["PythonExceptionInfo"] does not exist. The file version of my IronPython assembly is 2.0.20209.0 Any hint how to get more error details? cheers, Achim

  • Microsoft Quotation

    - by Asad Jibran Ahmed
    I don't know if this is the right place to ask this question, but I honestly have exhausted my self searching for the last hour. I am looking for a quotation made about Microsofts software. It goes something along the lines of: "They may make 2nd grade crappy software, but by God they know how to design interfaces" It was by a somewhat popular open source personality about the lack of good interface design in open source software. Does any one know the exact quotation? It will be a great help if someone can point me in the right direction.

  • .Net Compact Framework 2.0 touch and nice controls [.netcf 2.0]

    - by eridem
    Hello! I would like to know if somebody knows free custom nice controls for .NET Compact Framework 2.0. There are nice controls as Manila Interface SDK (http://forum.xda-developers.com/showthread.php?t=566188), Sense Interface SDK (http://forum.xda-developers.com/showthread.php?t=648906) and so on for free, but they work only on .NET CF 3.5. Furthermore, there are others that you have to pay for them and for .NET CF 2.0 and 3.5 (Resco or Touch Control Suite). And there is one called Fluid (http://fluid.codeplex.com/) but it's so complicated, there are not exactly controls (are classes added to a host control) and there is not much documentation to work with it. Any nice controls for free and working in .NET CF 2.0? And with list sliders if it's possible? Thanks!

  • Translate ImageButton from C# to XAML

    - by Bill
    I worked out the C# code to create an ImageButton (below) that has three images (one base-image and two overlays) and three text boxes as the face of the button. I am inheriting from the Button class, which unfortunately includes several components that I didn't realize would surface until after coding and need to remove, namely the bright-blue surrounding border on IsMouseOver, and any visible borders between the buttons, as the buttons will end up in a wrapPanel and the borders need to be seamless. Now that the format has been worked out in C#, I expect that I need to translate to XAML so that I can create a ControlTemplate to get the functionality necessary, however I am not certain as to the process of translating from C# to XAML. Can anyone steer me in the right direction? public class ACover : Button { Image cAImage = null; Image jCImage = null; Image jCImageOverlay = null; TextBlock ATextBlock = null; TextBlock AbTextBlock = null; TextBlock ReleaseDateTextBlock = null; private string _TracksXML = ""; public ACover() { Grid cArtGrid = new Grid(); cArtGrid.Background = new SolidColorBrush(Color.FromRgb(38, 44, 64)); cArtGrid.Margin = new System.Windows.Thickness(5, 10, 5, 10); RowDefinition row1 = new RowDefinition(); row1.Height = new GridLength(225); RowDefinition row2 = new RowDefinition(); row2.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row3 = new RowDefinition(); row3.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row4 = new RowDefinition(); row4.Height = new GridLength(0, GridUnitType.Auto); cArtGrid.RowDefinitions.Add(row1); cArtGrid.RowDefinitions.Add(row2); cArtGrid.RowDefinitions.Add(row3); cArtGrid.RowDefinitions.Add(row4); ColumnDefinition col1 = new ColumnDefinition(); col1.Width = new GridLength(0, GridUnitType.Auto); cArtGrid.ColumnDefinitions.Add(col1); jCImage = new Image(); jCImage.Height = 240; jCImage.Width = 260; jCImage.VerticalAlignment = VerticalAlignment.Top; jCImage.Source = new BitmapImage(new Uri(Properties.Settings.Default.pathToGridImages + "jc.png", UriKind.Absolute)); cArtGrid.Children.Add(jCImage); cArtImage = new Image(); cArtImage.Height = 192; cArtImage.Width = 192; cArtImage.Margin = new System.Windows.Thickness(3, 7, 0, 0); cArtImage.VerticalAlignment = VerticalAlignment.Top; cArtGrid.Children.Add(cArtImage); jCImageOverlay = new Image(); jCImageOverlay.Height = 192; jCImageOverlay.Width = 192; jCImageOverlay.Margin = new System.Windows.Thickness(3, 7, 0, 0); jCImageOverlay.VerticalAlignment = VerticalAlignment.Top; jCImageOverlay.Source = new BitmapImage(new Uri( Properties.Settings.Default.pathToGridImages + "jc-overlay.png", UriKind.Absolute)); coverArtGrid.Children.Add(jCImageOverlay); ATextBlock = new TextBlock(); ATextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); ATextBlock.Margin = new Thickness(10, -10, 0, 0); cArtGrid.Children.Add(ATextBlock); AlTextBlock = new TextBlock(); AlTextBlock.Margin = new Thickness(10, 0, 0, 0); AlTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(AlTextBlock); RDTextBlock = new TextBlock(); RDTextBlock.Margin = new Thickness(10, 0, 0, 0); RDTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(RDTextBlock); Grid.SetColumn(jCImage, 0); Grid.SetRow(jCImage, 0); Grid.SetColumn(jCImageOverlay, 0); Grid.SetRow(jCImageOverlay, 0); Grid.SetColumn(cArtImage, 0); Grid.SetRow(cArtImage, 0); Grid.SetColumn(ATextBlock, 0); Grid.SetRow(ATextBlock, 1); Grid.SetColumn(AlTextBlock, 0); Grid.SetRow(AlTextBlock, 2); Grid.SetColumn(RDTextBlock, 0); Grid.SetRow(RDTextBlock, 3); this.Content = cArtGrid; } public string A { get { if (ATextBlock != null) return ATextBlock.Text; else return String.Empty; } set { if (ATextBlock != null) ATextBlock.Text = value; } } public string Al { get { if (AlTextBlock != null) return AlTextBlock.Text; else return String.Empty; } set { if (AlTextBlock != null) AlTextBlock.Text = value; } } public string RD { get { if (RDTextBlock != null) return RDTextBlock.Text; else return String.Empty; } set { if (RDTextBlock != null) RDTextBlock.Text = value; } } public ImageSource Image { get { if (cArtImage != null) return cArtImage.Source; else return null; } set { if (cArtImage != null) cArtImage.Source = value; } } public string TracksXML { get { return _TracksXML; } set { _TracksXML = value; } } public double ImageWidth { get { if (cArtImage != null) return cArtImage.Width; else return double.NaN; } set { if (cArtImage != null) cArtImage.Width = value; } } public double ImageHeight { get { if (cArtImage != null) return cArtImage.Height; else return double.NaN; } set { if (cArtImage != null) cArtImage.Height = value; } } }

  • How do I load SciLexer.dll in Visual Studio 2008 Designer, on Windows 7 64-bit?

    - by Filini
    We develop a WinForm application using Scintilla.NET (1.7) component, which uses SciLexer.dll (unamnaged). At run-time, we distribute both 32bit and 64bit SciLexer.dll, and we load the correct one when the application starts (everything works fine). On our new development environments (Windows 7 64-bit), all our solutions build and run just fine, but the WinForm visual designer does not load our forms/controls which use Scintilla.NET, because it cannot load the correct SciLexer.dll: Window class name is not valid. at System.Windows.Forms.NativeWindow.WindowClass.RegisterClass() at System.Windows.Forms.NativeWindow.WindowClass.Create(String className, Int32 classStyle) at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg, IntPtr wParam, IntPtr lParam) at Scintilla.ScintillaControl.SendMessageDirect(UInt32 msg) at Scintilla.ScintillaControl.get_CodePage() at Scintilla.ScintillaControl..ctor(String sciLexerDllName) at Scintilla.ScintillaControl..ctor() Where does Visual Studio 2008 look for unmanaged libraries? I tried putting the 64-bit SciLexer.dll in SysWOW64, in the folder where ScintillaNET.dll is referenced, adding a folder in PATH system variable, adding a folder reference in the project, but I keep getting this error. Any help is appreciated.

  • SQL Server Compact 'Data Directory' macro in Connection String - more info needed

    - by codeulike
    So, as described on this msdn page, when you define a Connection String for SQL Server Compact 3.5, you can use the "Data Directory" macro, like this: quote from this msdn page: Data Directory Support SQL Server Compact 3.5 now supports the Data Directory macro. This means that if you add the string |DataDirectory| (enclosed in pipe symbols) to a file path, it will resolve to the path of the database. For example, consider the connection string: "Data Source= c:\program files\MyApp\Mydb.sdf" When using Data Directory, you can instead use the following connection string: "Data Source = |DataDirectory|\Mydb.sdf" For more information, see How to: Deploy a SQL Server Compact 3.5 Database with an Application. However, the 'for more information' link on msdn doesn't actually give any more information. So my question is: How does the |Data Directory| macro translate at run time? For WinForm apps, it seems to just give the location of the executable. Or is it more complicated than that?

  • how to invoke onclick function in html from vb.net or C#

    - by vbNewbie
    I am trying to invoke the onclick function in an html page that displays content. I am using the httpwebreqest control and not a browser control.

  • Cross Thread Exception in PropertyChangedEvent in WPF

    - by Ashish Ashu
    I have a ListView that is binded to my custom collection. At run time , I am updating the certain properties of my entity in my custom collection in my ViewModel. At the same time , I am also doing the custom sorting in the listview. The custom sorting is applicable when I click on the any column header of the listview. For example, I am updating the current datetime on my entity on every 5 seconds and simulaneously , I am applying custom sorting based on DateTime. (The Listview is third party control). Hence I am doing two operations on my custom collection at the same time. Should I pass the dispatcher of my control in the view model and call any methods ( which updates any entity in my custom collection ) through UI dispatcher ?

  • Django vs. Pylons

    - by Kenneth Reitz
    I've recently become a little frustrated with Django as a whole. It seems like I can't get full control over anything. I love Python to death, but I want to be able (and free) to do something as simple as adding a css class to an auto-generated form. One MVC framework that I have really been enjoying working with is Grails (groovy). It has a FANTASTIC templating system and it lets you really have full control as you'd like. However, I am beyond obsessed with Python. So I'd like to find something decent and powerful written in it for my web application development. Any suggestions? Pylons maybe?

  • SSIS DTS Package flat file error - "The file name specified in the connection was not valid"

    - by MisterZimbu
    I have a pretty basic SSIS package that is attempting to read a file hosted on a share, and import its contents to a database table. The package runs fine when I run it manually within SSIS. However, when I set up a SQL Agent job and attempt to execute it, I get the following error: Executed as user: DOMAIN\UserName. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 64-bit Copyright (C) Microsoft Corp 1984-2005. All rights reserved. Started: 10:14:17 AM Error: 2010-05-03 10:14:17.75 Code: 0xC001401E Source: DataImport Connection manager "Data File Local" Description: The file name "\10.1.1.159\llpf\datafile.dat" specified in the connection was not valid. End Error Error: 2010-05-03 10:14:17.75 Code: 0xC001401D Source: DataAnimalImport Description: Connection "Data File Local" failed validation. End Error DTExec: The package execution returned DTSER_FAILURE (1). Started: 10:14:17 AM Finished: 10:14:17 AM Elapsed: 0.594 seconds. The package execution failed. The step failed. This leads me to believe it's a permissions issue, but every attempt I've made to fix it has failed. What I've tried so far: Run as the SQL Agent account (DOMAIN\SqlAgent) - yields same error. DOMAIN\SqlAgent has "Full Control" permissions on both the share and the uploaded file. Set up a proxy account with a different account's credentials (DOMAIN\Account) - yields same error. Like above, "Full Control" permissions were given over the share to that account. Gave "Everyone" full control permissions over the share (temporarily!). Yielded same error. Manually copied the file to a local path and tested with the SQL Agent account. Worked properly. Added an ActiveX script task that would first copy the remotely hosted file to a local path, and then have the DTS package reference the local file. Gave a completely nondescriptive (even by SSIS standards) error when trying to run the script. Set up a proxy account, using my own personal account's credentials - worked correctly. However, this is not an acceptable solution as there are password policies in place on my account, as well as being a bad practice to set things up this way in general. Any ideas? I'm still convinced it's a permissions issue. However, what I've read from various searches more or less says giving the executing account permissions on the share should work. However, this is not the case here (unless I'm missing something obscure when I'm setting up permissions on the share).

  • WPF Pass MenuItem selected as MethodParameter to ObjectDataProvider

    - by Shravan
    I am trying to pass Selected MenuItem's Text/Header string as the MethodParameter to my ObjectDataProvider. I have seen examples like these on the internet but haven't been able to adapt it to the Menu Control specifically. I am new to WPF and need some help accomplish this.

  • How can a component at designtime determine the project directory

    - by Heinz Z.
    Hello, I write a component which should store some information relative to the project directory. Every time a property of my component is changed it should write a file. So how can a component determine the current project directory at design time. Thanks in advance EDIT: I want to generate a delphi source file every time a property of my component is changed, so that I always get the latest version when I compile my code. Think of it as a kind of code generator. At the moment I set whole path and filename where the source should be stored but I prefer a relative path to the project (or the form/datamodule which contains my component) to make it easier to copy the project on different developer machines.

  • How can I provide a different rendering target to Direct2D?

    - by fingerprint211b
    I'm using Direct2D in C# to render a small gui framework for my research project. I'm not very used to working on Windows or with DirectX. I'm using a Windows Forms control to create a render target, and msdn warns that since it uses BindDC, a the larger the rendering target, the worse the performance will be (which turned out to be a dramatic difference, when I maximize the window, I get around 15 fps). What would be a better way to create a render target for Direct2D? Is there a way to create a window and render directly to it, instead of rendering to a control's buffer first, and then rendering that? If so, how? Sorry if my English sucks, not my native language.

  • Avoid painting over nested controls

    - by Cobus Kruger
    I am writing a toolbar-style control and use the ThemeServices unit to paint the background required by the toolbar. Like so: ThemeServices.DrawElement(Canvas.Handle, ThemeServices.GetElementDetails(trRebarRoot), ARect); I then drop child controls onto the toolbar and voila - instant toolbar. Except that every now and again I notice that the nested (child) controls don't repaint as well. So my control paints its background and the child controls disappear until you move the mouse over them. Some of the edit controls show their client area (no border) and some of them are just gone altogether. This happens mostly when I place a window from another application over the toolbar and move it away. I keep thinking this has to be very easy to cure, that perhaps I'm somehow preventing the paint message from reaching the child controls, or missing an override but I have been unable to figure it out.

  • URL Routing with WebForms, what to do with additional querystrings like page number, filter, etc?

    - by Scott
    I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

  • Good implementations of reinforced learning?

    - by Paperino
    For an ai-class project I need to implement a reinforcement learning algorithm which beats a simple game of tetris. The game is written in Java and we have the source code. I know the basics of reinforcement learning theory but was wondering if anyone in the SO community had hands on experience with this type of thing. What would your recommended readings be for an implementation of reinforced learning in a tetris game? Are there any good open source projects that accomplish similar things that would be worth checking out? Thanks in advanced Edit: The more specific the better, but general resources about the subject are welcomed. Follow up: Thought it would be nice if I posted a followup. Here's the solution (code and writeup) I ended up with for any future students :). Paper / Code

  • ASP.NET AJAX UpdatePanel problem

    - by Velika
    I'll try and be concise: 1) I have a dropdownlist with Autopostback set to TRUE 2) I have an UpdatePanel that contains a Label. 3) When the downdownlist selection is changed, I want to update the label. Problem: Focus is lost on the dropdownlist, forcing the user to click on the dropdownlist to reset focus back to the control. My "solution": In the DropDownList_SelectionChanged event, set focus back to the drop down list: dropdownlist1.focus() Problem: While this works great in IE, Firefox and Chrome change the scroll position such that the control which was assigned focus is positioned at the bottom on the visible portion of the browser window. This is often a very disorientating side effect. How can this be avoided so it works in FF as it does in IE?

  • How do I make a textbox that only accepts numbers?

    - by Mykroft
    I have a windows forms app with a textbox control that I want to only accept integer values. In the past I've done this kind of validation by overloading the KeyPress event and just removing characters which didn't fit the specification. I've looked at the MaskedTextBox control but I'd like a more general solution that could work with perhaps a regular expression, or depend on the values of other controls. Ideally this would behave such that pressing a non numeric character would either produce no result or immediately provide the user with feedback about the invalid character.

  • uzing libgz to inflate a gz input

    - by Pierre
    Hi all, I'm currently trying to use the zlib to inflate a source of gzipped data. It seems that the inflate API in zlib cannot inflate a gzipped data ( The example http://www.zlib.net/zpipe.c fails to read a gzipped file: "zpipe: invalid or incomplete deflate data" ). I noticed that there is a gzopen function in this API, but , as far as I understand, it only works with a filename or a file descriptor. Can I use this API if my source of gzipped data is stored in memory, in a sql blob, etc... ? Many Thanks Pierre

I have never EVER in my whole life worked with ASP.Net, nor HTML and I never ever did a web page or web application before. I certainly find myself worried that I will lose all the comfort and joy I live every day coding in WPF. And in the other hand I understand and have seen in these 3/4 months of job hunting that there's a LOT of ASP.Net and really really little or no WPF in the job market (at least here), so I somehow feel forced towards it. So, my question is: Can anybody who had to go thru this type of change tell me the pros and cons of working with these technologies from a developer's perspective? I don't care about open-source / non-microsoft or non-desktop, I care about REAL development experience in every day working with these techs, and whether ASP.Net MVC 4 + HTML + JS is as crappy as I think it is comparing it to WPF.

  • Linq Query Help Needed

    - by Randy Minder
    Say I have the following LINQ queries: var source = from workflow in sourceWorkflowList select new { SubID = workflow.SubID, ReadTime = workflow.ReadTime, ProcessID = workflow.ProcessID, LineID = workflow.LineID }; var target = from workflow in targetWorkflowList select new { SubID = workflow.SubID, ReadTime = workflow.ReadTime, ProcessID = workflow.ProcessID, LineID = workflow.LineID }; var difference = source.Except(target); sourceWorkflowList and targetWorkflowList have the exact same column definitions. But they both contain more columns of data than what is shown in the queries above. Those are just the columns needed for this particular issue. difference contains all rows in sourceWorkflowList that are not contained in targetWorkflowList Now what I would like to do is to remove all rows from sourceWorkflowList that do not exist in difference. Could someone show me a query that would do this? Thanks very much - Randy
