• What's the ROI of using a build tool like ant or nant?

  - by leeand00

  To me this sounds like a really stupid question. Why would you not use a build tool? However, I need to explain my co-worker why he should be using a build tool of some sort. He's getting really into the idea of working as a team with more programmers, but he isn't understanding the bigger picture of what needs to change in the build process in order to work with a larger team; (i.e. defensive programming/unit testing your code, having a bug database, programming modular libraries, and using sub-repositories to store modules in version control. This is a rather large stack of technologies that I need to prove the ROI of...so I figured I'd start with the ROI of using a build tool rather than just...say...clicking compile.

• How to make autocompleting textbox in vb6 like this one?

  - by Amit Kumar Jha

  hey all, well i want to have an autocompleting textbox like the one in the image below: this screenshot is from an accounting software. whenever the user focuses on a textbox and starts typing something the suggestions just popup under the control (as seen in the image under the Purc type textbox).This autosuggest functionality even works in the cells of the grid shown in the picture.Moreover the fields in which this autosuggest is enabled allows only values from the autosuggest list to be filled up and nothing else. i want to emulate similar functionality in my app in vb6. so if you could please guide me in the right direction i would be very grateful. thanks in advance to all those who take out time to reply.

• WPF DataGrid Vs Windows Forms DataGridView

  - by Mrk Mnl

  I have experience in WPF and Windows Forms, however have only used the Windows Forms DataGridView and not the WPF DataGrid (which was only included in .Net 4 or could be added to .Net 3.5 from Codeplex, I understand). I am about to devlop an app using one of these controls heavily for large amounts of data and have read performance is an issue with the WPF DataGrid so I may stick to the Windows Forms DataGridView.. Is this the case? I do not want to use a 3rd party control. Does the Windows Forms DataGridView offer significant performance over the WPF DataGrid for large amounts of data? If I were to use WPF I would prefer to use .Net 3.5S SP1, unless the DataGrid in the .Net 4 is significantly better? Also I want to use ADO with DataTable's which I feel is better suited to Windows Forms..

• scrollable tab bar widget solution

  - by opensas

  I have a web page that I use to update a fairly complex data structure. The page itself has lots of information, so I developed some simple Tab-page control, with plain html. Each tab is a different page, so when the user click on a tab a post is issued to the new page. Fairly simply. The problem is that the page has about 10 tabs, so it no longer fits on screens. I'd like to know if you can advice some way to develop a scrollable tab bar or any other way to overcome this situation. maybe a widget or something... thanks a lot saludos sas

• Fluid Columns with matching height and background image

  - by JamesArmes

  I'm working on a new layout for my site that uses a header, footer and two column center region. The two columns consist of the main content area which is fluid height and width and a right sidebar which is fluid height and fixed width. I have done similar layouts before, but this one depends on using two different background images (one for the sidebar and one for the content area). Is there any way to implement this, using proper HTML & CSS, so that the background images of the two columns are always the same height, regardless of which columns content is longer? I've tried using JavaScript to simulate this, but it doesn't work so well if there are images in the content area. I would really prefer not to use this method any way. Any help is greatly appreciated. I have setup a staging environment at http://staging.jamesarmes.net/jimmyssandbox to provide an example. This environment is not my finished product, but I want to get the containers under control before I move any further

• Cross-platform GUI toolkits with WPF-style composition capabilities

  - by Alexey Romanov

  A huge advantage of WPF over, say, WinForms is its composability. To quote Programming WPF: One level up, WPF provides its “content model,” which allows any control to host any group of other controls. You don’t have to build special BitmapButton or IconComboBox classes; you put as many images, shapes, videos, 3D models, or whatever into a Button (or a ComboBox, ListBox, etc.) as suit your fancy. Are there any cross-platform GUI frameworks (preferably with Java bindings) out there which also let you do this?

• What are the app pool identity and account for anonymous access for?

  - by apollodude217

  I understand what the two are used for, except I don't know what each does--i.e. what one is for vs. what the other is for. (I usually set them to the same account anyway.) If you're not sure what accounts I'm talking about, in the IIS manager thingy: Right-click on the app pool in question, go to Properties, and click the Identity tab to see the App Pool Identity. Right-click a Web site, go to Properties - Directory Security, and click Edit under Anonymous Access and authentication control to view the Account for anonymous access.

• Surely there is a better grid than DataGrid for the .NET Compact Framework...

  - by PavelR

  Having spent a couple of days wrestling with DataGrid in .NET CF, especially controlling the look and feel, I'm looking for alternatives. I don't mind purchasing a solution. I'm looking for Redistributable to our enterprise customers. We control the hardware so it doesn't have to work perfectly on every device. Display strings and numbers in columns with headings. Scrollable, but no paging. Don't row editing. Need to add and delete rows. User re-sizable column widths, and a way to persist that. Work with .NET CF 2.0 or 3.5 on Windows CE 6.0 Any suggestions on grids or toolkits?

• Keyboard event issue

  - by Petar Minchev

  Hello guys! I have to capture the following keyboard event in a TextBox - SHIFT + 8(on the numpad). This also means the NumLock will be on. When I try the following, nothing is printed: private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Shift && e.KeyCode == Keys.NumPad8) Console.WriteLine("SHIFT + UP"); } But CTRL + 8(on the numpad) is working. private void textBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.NumPad8) Console.WriteLine("CTRL + UP"); } Could someone explain me, why SHIFT + 8 isn't fired, but CTRL + 8 is working? P.S. I wrote + UP, because the user wants to navigate with the numpad arrows and the SHIFT key, but his NumLock will also be on. That's why I catch Keys.NumPad8. All the best, Petar

• Ajaxcontroltoolkit VS. jQuery

  - by Jonesy

  hi folks, I asked a question a few days ago about how to customise the calendar extender of the ajaxcontroltoolkit library and got a response saying I should ditch the control kit for jQuery. I have to say I've heard jQuery being mentioned quite a bit and more importantly I've seen it as a requirement for an increasing number of web development job vacancies. I do like the ajaxcontroltoolkit with its simplicity and integration with Visual Studio. Does anyone have an opinion on the two of these? I'd love to hear from developers with experience with both these ajax solutions. -- Jonesy

• Invalid Memory Acess for JavaFX ScrollBar

  - by Mike Caron

  I created the following JavaFX script, which when run, generates an Invalid memory access. What is it about javafx.scene.control.ScrollBar that is causing a memory failure?

• dynamic silverlight content

  - by Jeremy

  I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

• Making the shadow from a ScatterViewItem a different shape

  - by Vargen

  I am developing a program for Surface using Expression Blend and Visual Studio. I have a custom user control with an ellipse and a label in a grid. This will need to be placed in a scatterViewItem. My problem is that the scatterviewitem will cast a rectangle shaped shadow under the ellipse shaped content. I can disable the shadow completely, but is there any way to make the shadow inherit the shape from its parent? Or can i set the shape of the scatterviewItem itself in any way?

• FOR XML PATH Query results to file with SSIS

  - by whimsql

  In SSMS I've gotten my for xml path query written and it's beautiful. I put it in an "Execute SQL Task" in the Control Flow, set the resultset to XML. Now how to I get the results into an actual xml file that I can turn around and FTP to a third party? This should have been so easy! I would put the XML into a variable but we are looking at a HUGE file, possibly 100mb+ Do I need to use a Script Task? (I'd like to avoid that if there is another option.)

• Protect files from svn commit.

  - by chrsk

  Hey, imagine a plain webapp with a log4j.properties which is under version control. I can't add it to svn:ignore because its a mandatory file. If i make custom changes for development and i don't want to commit them, i have to watch out for accidently commits. For one file it's easy to handle, with 3 or more files it becomes creepy. Is there a way to disable these files temporary from svn commit? So its easiert to commit? I'm working with svn and subclipse.

• NHibernate and SetSessionAuth audit columns

  - by user86431

  We have audit columns set by triggers. For obscure security reasons predating my tenure and out of my control, we log in with a generic user, and do a 'set session authorization' to change the user to the db user of the user who is logged in. When we converted to NHibernate, it creates a whole new session and jacks everything up when we try to do a set session auth, so we turned the set session auth off... Now we are trying to find out a way to get NHibernate to let us do 'set session authorization' without recycling the session on us, so we can use our existing trigger based audit column stuff with both legacy apps, and our new NHibernate apps. It's not a ideal soloution, or the best way to do it even, but is it possible? I was hoping there was a alternate interface that allowed this kind of access. Does anyone know how to do it, or can you point me towards and good hints? Thanks, Eric-

• How can you configure or extend BITS (Background Intelligent Transfer Service) to read files from a

  - by Mark

  I have a ASP .NET load balanced application (webservice and website). It runs on SQL server. I need to be able to provide large files for download. However, because of the load balancing situation, the files are stored in the SQL database as opposed to the file system. BITS seems to be the best approach. I have full control of the client. However, i don't know how to configure BITS to read the file from the database. I know how to write the C# code for that, but i don't know how to get BITS to hook into it as opposed to reading the file from the file system. Any ideas?

• How a servlet can get the absolute path to a file outside of the servlet?

  - by WolfmanDragon

  We have been using System.getProperties("user.dir") to get the location of a properties file. Now that it has been deployed on Tomcat(via servlet), the System call is giving the location as tomcat and not at the location at where the properties file exist. How can we call the the properties file dynamically? Given: Tomcat is not the only way the app will be deployed We have no control on where the app may be placed. Relative paths will not work as that Vista is being used and Vista breaks relative paths. This must work on all OS, including(but not limited to) Linux, XP and Vista. EDIT I implied this, but in case I was not clear enough, I have no way of knowing the path String.

  Hi, while trying to use the "InfoStrat"-Bing-Maps-Control in Expression Blend 4 for my Surface Application, I get the error message: "Mixed mode assembly is built against version v2.0.50527 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information" I already found out that I need to write this configfile: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> But Expression Blend doesn't seem to recognize that it is there. So how can I solve this problem?

Can anybody say why this could happen?

• What documents/requirements do you need from clients to develop web projects ?

  - by kacalapy

  I have an interview coming up where I would be a consultant to a small advertising agency. They crank out web sites for clients using DNN. tTe company owner/ operator asked me what I need in order to run with something and get it done, and eluded to wire frames and a site map. I am more used to having more detailed work and in a full time company environment but in these times it looks like we all need to be a bit more flexible. Typically I have functional and non-functional specifications defined for development work. This way I can control what is in scope, manage expectations, get sign offs, track deliverables and so on. Are there any contractors out there who develop web sites andcan advise me on the best approach to this so that I don't look foolish and get burned or taken advantage of? thanks

• Distinguish UI change to variable from code-behind change

  - by Jay

  Like the title says I am trying to architecture into my application a way to distinguish the source of a variable change, either from UI or code-behind. My problem is that I need to trigger some action after a property changed its value, but I only need to do this when the change comes from the UI because otherwise I don-t want to perform that action. I am having some trouble because, for example when a checkbox(two way binding), changes state, my binded property gets updated and then I use the checked and uncheked events to trigger that action.The problem is that when I change the property in codebehind it also triggers those events and I do not want that. Right now, i am using a flag that enables, or not, the actions at the event handlers but I do not feel that this is a good idea. Any sugestions or ideas? I am considering using only one-way binding and control everything my self, using commands.

• ASP.NET (AJAX) UI Design Tools for Artistically Challenged?

  - by davemackey

  I'm building an application but I'm artistically challenged and I'd rather not spend my time writing widgets (e.g. ability to collapse/expand/close/drag-drop) if there is already controls available. I've worked with the Microsoft AJAX Control Toolkit - but these tools still require a lot of work to get a working widget (which in my case, won't look too pretty). The CollapsiblePanel is pretty nice - but then you have to program in the minimize button, close button, maximize button, etc. Looking for suggestions that will help me design better UI faster...
