• Visual Studio 2008 (Pre-release) vote for extension properties

  I was playing with extension methods the other day, and I find it really exciting. The natural language expressiveness is great, epecially when creating a Domain Specific Language for an app or framework. Some uses were natural for methods, such as a Behavior-Driven Development style of testing method like: public static bool ShouldBeEmpty( this ICollection coll ) { return coll.Count == 0; } // var x = new ArrayList(); x.ShouldBeEmpty(); returns true Other uses were not so natural, where the parentheses get in the way. public static TimeSpan Months( this int number ) { var now = DateTime.Now; return now.AddMonths( number ) - now; } public static DateTime FromNow( this TimeSpan span ) { return DateTime.Now + span; } ...Show All

• SharePoint Products and Technologies Programmatic Audience Compilation

  Is there a way to fire off the audience compilation process through c# Specifically, if I wanted to compile just one audience but not the rest, is it possible to do this through code Thanks in advance for any help offered. Dez Actually, it seems that the audience compilation is possible through the object model. The AudienceJob class has a static method called RunAudienceJob that provides a way to start and stop incremental and full compilation. Althoug, it requires some parameters I can't find. Here is the SDK : public static int RunAudienceJob ( string [] args ) Parameters args Takes the following four arguments: ApplicationID ...Show All

• Community Chat Connect to a database

  Can anyone give me simple code for visual studios.net 2003 for a connection to a database. I have trawled through sites for 2 days now to no joy whatsoever! thanks. Your questions is probably best handled on the SQL site for future reference. That said, there are lots of examples of the code on MSDN if you look at the official documentation associated with any of the classes related to accessing SQL. For example, there's a pretty simple example that I think should be compatible with both VS2003 and VS2005 here: http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqldataadapter.aspx ...Show All

• Visual Basic Printout is not what I expected

  I need some help with the following problem. I have made a simple pos system that will let the user push buttons that represent the menu items and those items show up on the reciept. I am using formatting zones to line up the items. This part of the program works fine and the display on the screen keeps everything lined up. My data is contained inside of a sorted list and my objects come from a menuitem class the properties are : name - holds the name of the menuitem price- holds the price cost - holds price * Quantity Quantity - how many key - so each entry into the sorted list is unique The name of my sorted list is itemcoll And my theory is that i can loop through the sorted list and print each element until r ...Show All

• Windows Forms databound listbox

  I have 2 list boxes. Both are databound. I have an add button and remove button. when the add button is pressed the selected record should be moved from list box 1 to list box 2. When the remove button is presse the selected record should be moved from list box 2 to list 1. It works pretty well - unless one of the list boxes are empty then I have all sorts of problems adding the new row (no primary key, no columns, etc..) I set the databound listboxes with: list.DisplayMember = DisplayName; list.ValueMember = ValueName; DataColumn [] dtCol = new DataColumn [1]; dtCol[0] = dtSrc.Columns[ValueName]; dtSrc.PrimaryKey = dtCol; list.DataSource = dtSrc; My remove button code is: private void cmdR ...Show All

• Windows Forms MonthCalendar Control XP Themes --- How do you disable?

  From MSDN note: Using the MonthCalendar with visual styles enabled will cause a selection range for the MonthCalendar control to not paint correctly and today's date to be contained in a square if ShowTodayCircle is set to true . How do you turn of xp themes for just the month calendar control I have been able to turn off for applciation but once you set it for one form then the month control on other forms begin messing up. There has to be an easy solution. Is there a hotfix we can apply Thanks, Aaron The classic fix, calling UxTheme.dll's SetWindowTheme(), sadly doesn't work. It just changes the month scroll buttons, not the rest of the control. I don't think there is (and couldn't fin ...Show All

• SQL Server Closing a conversation later on and Microsoft Service Broker Interface (sample)

  In a messaging application, a client sends a message to the server. The server uses Service Broker Interface, and is CLR based. On the server, the message has a life cycle - going throughout multiple transitions until is final (Pending, In Transit, Delivered, TimedOut, Undeliverable). As the server receives the message, it sends back to the client a reply status message of In Transit. It does so using the same message’s conversation. It also saves – along with the message – its conversation handle. The dialog is not closed. After a while, the server may decide that the message has gotten to a final state (Delivered or TimedOut). I would like at that time to send a reply status message (Final State) back to the client and also close th ...Show All

• Windows Forms CheckBoxList does not contain a public definition of 'GetEnumerator' error

  Hi, I have a CheckboxList on a web form. I want to cycle through the checkboxes in the list to determine which boxes have been checked. Seems easy enough..but I'm getting an error that the "CheckBoxList does not contain a public definition of 'GetEnumerator'". Here's my code: foreach ( CheckBox cb in cbSRlist) { // get Sales Region the user has access privs for if (cb.Checked){ Response.Write(cb.Text + "<BR>" ); } } ...the error is actually caused by the foreach statement which can't operate on the checkboxlist because it doesn't have a public def of 'getEnumerator. The same error occurs if I replace 'CheckBox' with 'ListItem' in the above foreach stmt. what am I missing th ...Show All
