    Hello. I have a control with two buttons (zoom in, zoom out). Both buttons have onClick event that handle the zoom. When any of the button is pressed, the button gets focus and bolds its border and text. Is there a way to disable/remove focus? Actually the solution im looking for would be that on mouseDown the button would receive focus and would lose it on mouseUp. thanx !

  • Configure ERP conectivity to a Flex application via a web service

    - by James
    I am developing a Flex application that will need to 'pull' information from an ERP system such as SAP or Peoplesoft via the clients web service. My application will need to pass credentials & query to a Query_URL and receive the returned data. I saw a Flash Builder 4 presentation where the Adobe evangelist created a similar application using Twitter. Insights or links to example code would be appreciated.

  • Looking for downloadable demo of a .Net service accessed through a pure JavaScript client, without r

    - by blueberryfields
    I am told that the configuration below is possible, but have had significant difficulty in finding instructions on how to set it up. While I'm trying to muddle my way through this on my own, maybe stack-overflow knows of better sources for documentation: I am looking for a walkthrough, including a downloadable, working example, for setting up the following configuration: Server-side .net application (For .net 2.0 or higher), installed/deployed as a windows' service (that is, not served through IIS), and accessed by a client tool that is completely implemented in JavaScript.

  • Build a custom drawn control for .net compact framework

    - by Hinek
    I just started on the .net compact framework. I want to draw a Sudoku field on the screen. So I put down a PictureBox and defined a method for the Paint event: private void pictureBoxPlayfield_Paint(object sender, PaintEventArgs e) { // use e.Graphics to draw the grid, numbers and cursor } This works, but you can see as the grid is drawn. So my question is, what is the right/better way to create such a custom control? Is there maybe a way to enable double buffering?

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • open source custom tooltip (callout) control/code for asp.net

    - by dotnetcoder
    Looking for a custom tooltip (typical yellow baloon callout) on click of an anchor tag. The tooltip should appear and remain in view until the cross button on the tooltip is clicked. Just looking for a tried and tested open source solution. Tried googling this but most of the tooltip [...missing info?...] Ajax control toolkit has the calloutvalidator which seems like a good choice but is tied up to be used for validation tooltips.

  • Access static Method in GDB

    - by Besi
    I recently discovered the GDB in Xcode which makes up for some functionality which IMHO seems to be lacking in Xcode. So I can do the following in GDB: (gdb) po [LoginManager sharedSession].loginToken 20D52FE9-3573-437E-9A65-846572B63726 However, I have another Service class, which is currently not loaded so I get the following error: (gdb) po [SessionService displaySessionInfoForToken:@"XXX"] No symbol "SessionService" in current context. I don't understand why the LoginManager can be loaded but not the SessionService.
