• Silverlight (formerly WPF/E) rich User experience

  I guess we are at one of those times when there really is not a clear answer to a key problem and that is the delivery of rich ui experience in a browser. By this I do not mean animations and SVG but professional looking forms(input), trees, menus and dialogs. These are the artifacts that of course WinForms have and of course one can deliver much the same experience in a Web App but the energy to deliver it is tremendous. We write a lot of Javascript and CSS and then battle with the thankless and sometimes unsolvable cross browser issues. Recently we have started using controls from Telerik and I must say they are impressive. However they are just taking away some of the pain , what we really need is to have these capabilities in WPF/E as ...Show All

• Software Development for Windows Vista Design pattern for enlisting a "plain old API call" in a transaction?

  We have a third-party workflow server process that exposes a plain old managed .NET API with the following the following methods: 1. Connecting to the server 2. Setting datafields within the server 3. Causing the datafields to be updated within server 4. Closing the server We have a business object with a UpdateServer() method that accepts a collection of datafield values and calls the above methods to store them in the workflow server. We want to include the call to UpdateServer() amongst some database update calls. We need to have these calls to execute as a single transactions - i.e. the UpdateServer() and database updates are all executed; or they are all aborted/rolled back. In EnterpriseServices, I p ...Show All

• Visual Basic Validate textstring as DateTime

  Hello , Can this be done in VB2005Xpress Form elements: one TextBox, one Label (TextBox is used to receive Birthdate input, Label displays "<1", "1" "the age which is calculated from Today's Date - Birthdate" or " "). The age formula and the If statement for "<1", "1", "age" and " " is done. Here the TextBox is the choice for Birthdate entry. It is the most cost effective.

• .NET Development Shell Hooks in .NET

  I'm trying to play around with using a Windows hook to tell when different application windows are openned or activated. It's not working right; I'm not sure what's wrong. When I first run my application, there is at most one call to ShellProc. Here's what's really confusing me: if I change the argument to SetWindowsHookEx from WH_SHELL to WH_KEYBOARD_LL, then I get every single keyboard event that happens even in other applications. This is correct behavior. But when using WH_SHELL I never get more than one event, and sometimes not even that. Does anyone have any suggestions Win32 .

• Windows Forms [c#]ToolStripProgressBar on a BindingNavigator

  Hi all :) I would like to learn something about the ProgressBar. I have a form, with a datagridview that show some records of a database.

• Game Technologies: DirectX, XNA, XACT, etc. Problem installing XNA Game Studio Beta 2

Ran Visual C# then closed it 3. Tried to install beta 2 However when I try to install beta 2, it gets through most of the install, but after it does "installing DirectX redist" it goes to "rolling back action" and tells me that the install ended prematurely due to an error.

• SQL Server trigger for running totals

  Hello, I haven't had a lot of experience with triggers and I am trying to create a statement that will update one table with totals from columns in another table.

• SQL Server PPV's, Loops & Child Packages - Bug or By Design

  It would appear that if a Child package is called more than once from a Parent using the 'Execute Package' task, then after the first execute the Parent Package Variables are not applied to child package. I.E we build dimensions in a master database and these are then loaded to a number of topic specific datamarts. We simply pass Parent variables to the child that hold source & target connection strings, the first time the package is called the correct database is accessed, subsequent Executes ignore the variables and use the original values. Manipulating the (our) event queue to run the package once results in the correct behaviour Are packages cached when they are called from a Parent if so is there a flag that I have missed to fo ...Show All

• SQL Server Pre-Generating snapshots not working

  Hi I have setup my web synchronisation with very few problems until now. Initially I set the snapshots to generated by the subscriber when they first synchronise, this worked perfectly every time until a bottleneck occured after I reinitialised all the subscribers. When more than one subscriber then initialises the snapshot agent, the snapshot jobs fail because there is already a job running for user distributor_admin. The agent then retries etc, etc.. until all retries have failed. Ultimately only one of the snapshots is successfully created only after all other jobs have failed and run out of retries, it is then left alone to carry out its job. Following this I made the decision to run with pre-generated snapshots instead so that I can s ...Show All
