• WPF - DataGrid Column's ToolTip visibility based on the column's data length

  - by S.C.Vidhya

  In my application, i have tried to implement the visibility of tooltip based on the dataGrid Column's text length by using a converter. I am facing some problems in displaying the toolTip text. In the ToolTip, TextBlock's text binding is not working. If its binded with some hard coded strings, it works fine. Here below is the code that i have added for the grid column... <Custom:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Text}"> <TextBlock.ToolTip> <ToolTip DataContext="{Binding Path=PlacementTarget, RelativeSource={x:Static RelativeSource.Self}}" Visibility="{Binding Converter={StaticResource ToolTipVis}}"> <TextBlock Text="{Binding Text}"> </ToolTip> </TextBlock.ToolTip> </TextBlock> </DataTemplate> </Custom:DataGridTemplateColumn.CellTemplate>

• UISegmentedControl selected segment color

  - by Mike

  Is there any way to customize color of selected segment in UISegmentedControl? I've found segmentedController.tintColor property, which lets me customize color of the whole segmented control. The problem is, when I select bright color for tintColor property, selected segment becomes almost unrecognizable (its color is almost the same as the rest of segmented control, so its hard to distinguish selected and unselected segments). So I cannot use any good bright colors for segmented control. The solution would be some separate property for selected segment color but I cannot find it. Did anyone solve this?

• ADO Entity Framework 4 to WPF Datagrid. DatagridComboBox nightmare.

  - by Jason

  The WPF datagrid -seems- like it's going to work, but the combobox implementation does not work straight from the designer. So I'm left wandering around in the XAML randomly changing things trying to get it to work. The problems are numerous. I want to display a foreign key relationship (with drop down) instead of a bunch of numbers for a selection. It seems like it shouldn't be this hard. I can get the right values to show up (their description instead of an ID), but the table freaks out thinking that all the values have been modified. If I select a drop down, it refuses to allow me to edit anything else. I want to chalk this up as a .NET bug, but since I'm new to WPF datagrids, it's probably just me. Here is the code. <DataGridComboBoxColumn Header="Make Up" ItemsSource="{Binding Source={StaticResource materialMakeUpTypesViewSource}}" DisplayMemberPath="Description" TextBinding="{Binding Path=MaterialMakeUpType.Description}" SelectedItemBinding="{Binding Path=MaterialMakeUpType.Description}" SelectedValueBinding="{Binding Path=MaterialMakeUpType.ID}" />

• VMware Converter errors when creating Boot Camp VM

  - by Ryan Giglio

  I just got a new computer. My old computer had a Boot Camp installation of Windows 7, with VMWare running the Boot Camp installation in a virtual machine. On my new computer, I want Windows to strictly be a VM, so I downloaded the VMWare Converter software to create a virtual machine out of the Boot Camp partition. After finishing 95% of the converting process, I get a few messages Warning: Failed while updating boot.ini on the target machine's system volume. Warning: Failed while updating drive letters for the target volume layout. Error: Reconfiguration failed. And then it fails with FAILED: Unable to find the system volume, reconfiguration is not possible. I'm not sure what the problem is or how to fix it...I don't know much about virtualization or dual booting other than the simple instructions on how to set it up the first time.

• Improving ANTLR DSL parse-error messages

  - by Dan Fabulich

  I'm working on a domain-specific language (DSL) for non-programmers. Non-programmers make a lot of grammar mistakes: they misspell keywords, they don't close parentheses, they don't terminate blocks, etc. I'm using ANTLR to generate my parser; it provides a nifty mechanism for handling RecognitionExceptions to improve error handling. But I'm finding it pretty hard to develop good error-handling code for my DSL. At this point, I'm considering ways to simplify the language to make it easier for me to provide users with high-quality error messages, but I'm not really sure how to go about this. I think I want to reduce the ambiguity of errors somehow, but I'm not sure how to implement that idea in a grammar. In what ways can I simplify my language to improve parse-error messages for my users? EDIT: Updated to clarify that I'm interested in ways to simplify my language, not just ANTLR error-handling tips in general. (Though, thanks for those!)

• Delphi 2010 Professional and remote database access

  - by Kico Lobo

  Hi, When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Does this mean that we'll only face this restriction if we choose to use the native vcl components for database access we'll face this restriction. And what if we choose to use ADO components instead of those? In this case, how can Delphi avoid us to access remote database servers? Did anyone here ever tried this? Going even further: if we choose to use a database like Firebird, which is just one file, and used a network mapped drive. Could we be facing the same limitation? Supposing we opt for ADO, what will be the main consequences?

• C# - Recursive / Reflection Property Values

  - by tyndall

  What is the best way to go about this in C#? string propPath = "ShippingInfo.Address.Street"; I'll have a property path like the one above read from a mapping file. I need to be able to ask the Order object what the value of the code below will be. this.ShippingInfo.Address.Street Balancing performance with elegance. All object graph relationships should be one-to-one. Part 2: how hard would it be to add in the capability for it to grab the first one if its a List< or something like it.

• How to insert a date to an Open XML worksheet?

  - by Manuel

  I'm using Microsoft Open XML SDK 2 and I'm having a really hard time inserting a date into a cell. I can insert numbers without a problem by setting Cell.DataType = CellValues.Number, but when I do the same with a date (Cell.DataType = CellValues.Date) Excel 2010 crashes (2007 too). I tried setting the Cell.Text value to many date formats as well as Excel's date/numeric format to no avail. I also tried to use styles, removing the type attribute, plus many other pizzas I threw at the wall... Can anyone point me to an example inserting a date to a worksheet? Thanks,

• Windows "known folders": is there any one of them which is reliably read/write for all users on all

  - by Stabledog

  SHGetKnownFolderPath() and its cohorts accept one of the constants defined here (http://msdn.microsoft.com/en-us/library/dd378457%28v=VS.85%29.aspx ), returning the path to a directory. I'm looking for one of these folders which is reliably writable by all users (including LocalSystem) on XP, Vista, and Windows 7... but I think I'm striking out. It appears that, in fact, there is no single location on the hard drive anymore where you can put a file and be assured that all users can write to it on all these OS versions, without fiddling the permissions first. Is this true?

• How To Draw More Precise Lines using Core Graphics and CALayer

  - by user308444

  Hello I am having a hard time making this UI element look the way I want (see screenshot). Notice the image on the right--how the line width and darkness looks inconsistent compared to the image on the left (which happens to be a screen grab from safari) where the border width is more consistent. How does apple make their lines so perfect? I'm using a CALayer and the Core Graphics API to draw the image on the right. Is it possible to draw such perfect lines with the standard apis?

• Quick way to get an NSDictionary from an XML NSData representation?

  - by dontWatchMyProfile

  I've loaded an XML file as NSData into memory and parse over the elements using NSXMLParser. Although it works, it's a very ugly and hard to maintain code since there are about 150 different elements to parse. I know there are nice third-party solutions, but I want to keep it with the iPhone SDK for purpose of practice and fun. So I thought: Why not convert that XML file into an NSDictionary? Having this, I could use fast enumeration to go over the elements. Or is it just the same amount of ugly code needed to parse and process an XML right away with NSXMLParser? Would I build up an NSDictionary for every found node in the XML and create a huge one, containing the whole structure and data? Or is there an even simpler way?

• Comparison of the multiprocessing module and pyro?

  - by fivebells

  I use pyro for basic management of parallel jobs on a compute cluster. I just moved to a cluster where I will be responsible for using all the cores on each compute node. (On previous clusters, each core has been a separate node.) The python multiprocessing module seems like a good fit for this. I notice it can also be used for remote-process communication. If anyone has used both frameworks for remote-process communication, I'd be grateful to hear how they stack up against each other. The obvious benefit of the multiprocessing module is that it's built-in from 2.6. Apart from that, it's hard for me to tell which is better.

• Bogus InvalidOperationException (in a DataServiceRequestException)

  - by Andrei Rinea

  I am having a hard time with ADO.NET Data Services (formerly code-named Astoria) as it gives me a bogus exception when I try to insert a new entity from the silverlight client and trying in a clean project (the same code) doesn't. In both cases, however, data is correctly inserted into the database. Using Fiddler (an HTTP debugger I could see that there is no problem in the HTTP communication as I will show later in this question. The code : var ctx = new MyProject123Entities(new Uri("http://andreiri/MyProject.Data/Data.svc")); var i = new Zone() { Data = DateTime.Now, IdElement = 1 }; ctx.AddToZone(i); i.StareZone = new StareZone() { IdStareZone = 1 }; ctx.AttachTo("StareZone", i.StareZone); ctx.SetLink(i, "StareZone", i.StareZone); i.TipZone = new TipZone() { IdTipZone = 1 }; ctx.AttachTo("TipZone", i.TipZone); ctx.SetLink(i, "TipZone", i.TipZone); i.User = new User() { IdUser = 2 }; ctx.AttachTo("User", i.User); ctx.SetLink(i, "User", i.User); ctx.BeginSaveChanges(r =] ctx.EndSaveChanges(r), null); when run the last line (ctx.EndSaveChanges(r)) will throw the following exception : System.Data.Services.Client.DataServiceRequestException was unhandled by user code Message="An error occurred while processing this request."

• HTML form -> Flash submit button -> Set a PHP variable in flash button -> Submit form

  - by RobHardgood

  Okay, I'm sorry that this is pretty complicated, but it shouldn't be that hard to solve... Here's what I want to do. I have an HTML form that I want to upload to MySQL with PHP. That part's easy, but the thing is I want the submit button to be a Flash object. Somehow I need the Flash button to submit the form, but I think I can figure that out. The tricky part is that I need it to set another PHP variable before submitting the form. The variable will be determined by a bunch of stuff, but I can code that in actionscript later. I just need to figure out how to pass the variable back to the webpage. A $_POST variable would probably be fine. Thanks!! Let me know if I need to clarify more...

• Should I be afraid of Linux server administration?

  - by markle976

  I've been trying to figure out what to focus on. I finally realized that the root of my quandary is that I am unsure about learning Linux server administration. I have been getting pretty good with PHP/MySQL and web development, but I am not very familiar with Linux. Is it hard to learn? What would I need to know in order to manage a LAMP stack? Also, which version is most used in enterprises? I think I have also hesitated to dive in because it seems like it is mostly used in small companies, but I guess that could be a good thing.

• Choosing between Berkeley DB Core and Berkeley DB JE

  - by zokier

  I'm designing a Java based web-app and I need a key-value store. Berkeley DB seems fitting enough for me, but there appears to be TWO Berkeley DBs to choose from: Berkeley DB Core which is implemented in C, and Berkeley DB Java Edition which is implemented in pure Java. The question is, how to choose which one to use? With web-apps scalability and performance is quite important (who knows, maybe my idea will become the next Youtube), and I couldn't find easily any meaningful benchmarks between the two. I have yet to familiarize with Cores Java API, but I find it hard to believe that it could be much worse than Java Editions, which seems to be quite nice. If some other key-value store would be much better, feel free to recommend that too. I'm storing smallish binary blobs, and keys probably will be hashes of the data, or some other unique id.

• ODBC Connection Setup in Java

  - by Jessica

  I want to write a Java program that automates the work that the ODBC Data Source Administrator does in Windows. That is, given an ODBC connection name and a path to the database on the hard drive, I want it to create the connection. I really have no idea where to even begin with this. I looked at this but it said it was for C and I don't think that's very helpful. If anyone could point me in the right direction for this at all, I would appreciate it. (I realize this question is REALLY vague, but that's all the information I was given.)

• not using partial mocking? do they also mean in web-app?

  - by 01

  Im learning Mockito and in chapter 16 they say you should not use partial mocking in new system. I disagree, for example in one of my actions i use partial mocking for static framework methods, sql calls, etc. I extracted the stuff into methods and then mock it in tests. Most of those methods are specific to this action and wont be call from other actions, so it not worth to extract special components. I agree that you shouldn't using partial mocking in frameworks, but not in hard to mock actions. What are minuses of using partial mocking in web-app?

• How do I use a datetime variable with createparameter in classic ASP?

  - by Frank Schmitt

  I'm having a heck of a time trying to create a parameterized query that binds a date variable into a stored procedure call: twoyearsago = dateadd("yyyy", -2, date()) DataConn.ConnectionString = myConnectionString DataConn.Open Set rs = Server.CreateObject("ADODB.Recordset") Set DataCmd = Server.CreateObject("ADODB.Command") DataCmd.ActiveConnection = DataConn DataCmd.CommandText = "exec myStoredProc ?, ?" DataCmd.Parameters.Append DataCmd.CreateParameter("@start", adDate, , 10, date()) DataCmd.Parameters.Append DataCmd.CreateParameter("@end", adDate, , 10, twoyearsago) rs.Open DataCmd The stored proc returns nothing (indicating the dates aren't making it through). If I hard code dates in the query, e.g.: DataCmd.CommandText = "exec myStoredProc '01/01/2008', '01/01/2010'" I get the results I would expect. Calling CStr on my dates (if that makes a difference) returns them in the above format.

• How To AutoScroll a DataGridView during Drag and Drop

  - by Mason

  One of the forms in my C# .NET application has multiple DataGridViews that implement drag and drop to move the rows around. The drag and drop mostly works right, but I've been having a hard time getting the DataGridViews to AutoScroll - when a row is dragged near the top or bottom of the box, to scroll it in that direction. So far, I've tried implementing a version of this solution. I have a ScrollingGridView class inheriting from DataGridView that implements the described timer, and according to the debugger, the timer is firing appropriately, but the timer code: SendMessage(Handle, WM_VSCROLL, (IntPtr)scrollDirectionInt, IntPtr.Zero); doesn't do anything as far as I can tell, possibly because I have multiple DataGridViews in the form. I also tried modifying the AutoScrollOffset property, but that didn't do anything either. Investigation of the DataGridView and ScrollBar classes doesn't seem to suggest any other commands or functions that will actually make the DataGridView scroll. Can anyone help me with a function that will actually scroll the DataGridView, or some other way to solve the problem?

• Alternatives to using WebClient.BaseAddress to get base url in Silverlight

  - by Martin Liversage

  In a Silverlight application I sometimes need to connect to the web site where the application is hosted. To avoid hard coding the web site in my Silverlight application I use code like this: WebClient webClient = new WebClient(); Uri baseUri = new Uri(webClient.BaseAddress); UriBuilder uriBuilder = new UriBuilder(baseUri.Scheme, baseUri.Host, baseUri.Port); // Continue building the URL ... It feels very clunky to create a WebClient instance just to get access to the URL of the XAP file. Are there any alternatives?

• Three ways to upload/post/convert iMovie to YouTube

  - by user351686

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB.
