• Visual Studio 2008 (Pre-release) Hard to do exact positioning.

  I've just learned the basics of WPF and XAML but I find it very hard to do exact positioning in my programs. I've found out that you can use a Canvas and then use the item .SetValue( Canvas .LeftProperty, double); -function to place things, but thats a real hassle. Adding another canvas inside a canvas with exact layout doesn't work at all. I'm looking for the easiest way to place things X% from the left (relative from the usercontrols left edge, not the windows) with a width of Y%, i want my programs to work in fullscreen on all resolutions. Could you please give an example of how to animate a percentual ColumnDefinition Width. I had a similar problem like the OP and never managed to get anim ...Show All

• SQL Server What is Best way to Count the number of records in a table - Sql Server 2005

  I have a table with 54 million records But it take lot of time when i am using Count(*) or Count (ColumnName). What is best way to Count the records in Sql server 2005 Regards Vasanth select count(*) , select count(1) and select count(field) will all be the same. Try it, you will see. I am very happy to be wrong on this though If you want up to the minute counts that return very fast, look at creating an indexed view with the count in, inserts will take longer with this, but it depends on what your requirements are. I have a table with 235525 rows, this is that stats : SQL Server Execution Times:    CPU time = 47 ms,  elapsed time = 43 ms. (1 row(s) affected) Table 'FilePlanItem'. ...Show All

• SQL Server Encryption related overflow?

  Recently restored a SQL 2000 database to a SQL 2005 Server. The database contains a series of user stored procs (one calls upto 5 other sps) which are all encrypted using 'WITH ENCRYPTION' clause. When run on SQL 2000 Server this runs without error. When run on SQL 2005 Server it reports an error: Msg 565, Level 18, State 1, Procedure SPDM_MP1_SOURCE59, Line 5143 A stack overflow occurred in the server while compiling the query. Please simplify the query. Investigating the error line reported does not reveal any problems with the sp and the error line number reported is not always consistent. However, altering the stored procs so they are not encrypted and it all runs without error. Is there a compatibility issue running SPs e ...Show All

• Software Development for Windows Vista Tracking and Dependency Properties

  I have recently changed one of my Custom Activity Properties into a Dependency Property so I can use DataBinding.  However, now my tracking is messed up. The same property is used in both UserTracking and ActivityDataExtract, but the actual data that is emitted to tracking is just the Type Name of the property and not the serialized object itself. Now I have also made other changed that could have caused this, but anyone know if this sounds familiar or problematic Thanks, Dave ...Show All

• Visual Basic Skipping lines in a test file

  I routinely work with text files with well over 3200 lines of text. I am trying to write a routine that will parse the file and skip lines (example every 3 rd line) and save the new smaller text file. I am not a college kid trying to get someone to do his homework for him. I am just trying to teach myself to write simple programs that I find useful.

• Software Development for Windows Vista Timers in a Workflow hosted in ASP.Net

  Hi I'm building a web based workflow application and need to monitor the progress of the requests entered into the application and if a request hasn't been actioned after a period of time; send a notification email. I've read several posts and bloggs that state the Persistence service is responsible for monitoring Workflows that are in an idle state and then responding to delays within the Workflow that expire. I realise that because of the nature of ASP.Net the runtime is unloaded after each call, so I'm confused as to how, if the service isn't instantiated, it can perform this task. Thanks for any help. DB So if no one is using the application (over night for example) and a delay expires the ...Show All

• SharePoint Products and Technologies WSS 3.0. Should I upgrade?

  Hi, We have got WSS 2.0 installed with TFS v1 installation. Ever since we are using this system for our document library and collaboration. While using the system we discovered many issues in WSS 2.0 that can cause data loss. Given below are two main issues: 1) If a user (intentionally/unintentionally) deletes a document in WSS 2.0, all its versions get deleted with no option to recover. 2) It allows a second user to checkin document that is checked out by first user. That too without first user's knowledge. Now that WSS 3.0 is out, I'm wondering if it makes any sense to upgrade Does it solve issues like above Cheers! D2 Andrew, Thanks for your post.
