• Silverlight (formerly WPF/E) error handling?

  When a XAML element has an attribute that it doesn't support, nothing renders and there's no alert. I also tried specifying my own error handler, instead of the null argument in the new agHost(...) call. That wasn't called either. I hope this isn't the intended behavior, because it sure makes debugging difficult. If that's not the normal behavior, could someone suggest how I can get it to work, or at least allow it to render the whole XAML document ignoring the offending element Actually, I would expect that both the error handler would be called and everything else would be rendered and the offending attribute would be ignored. Perhaps the non-rendering behavior is due to over-zealous validation, but I don't think that is a wise ...Show All

• .NET Development Logging Data Truncation While Using SQLBulkCopy

  Hi, I am using SQLBulkCopy class of .Net 2.0 to copy data from excel to SQL 2000 database. My problem is that I want to log records whose data was been truncated as the field length in the database was not sufficient enough to hold data present in the excel file. For example suppose there is a column called 'Employee Name' in the database as varchar (30) now if I try to insert data using SQLBulkCopy class from excel file having data of more than 30 characters for some rows then somewhere I want a log which helps me to identify that row number 10 & column number 20's data was truncated due to field length.

• Windows Forms OWC in a windows forms app?

  Hey all, I know this may seem strange, but is there any reason I can't use an office web component in a windows forms application Alternatively, can someone suggest a way i can display pie charts / bar graphs etc... in a winform app without using the OWCs Thanks! There are many great chart components, but they are really expensive. Comparing them with chart from office is not an issue, believe me.

• Visual Studio Team System CTP7 BUG - Database Role Membership is not Compared

  I have created a custom database Role with grants and denies in the securables and one Role Member. When I do a schema compare the role membership is not considered regardless of the settings of the IDE (schema settings, project settings). When updates are written the role is created and the grants and denies are written (the latter if ignore permissions is not checked). HOWEVER - 1. The membership is never written meaning the user is stranded without a role membership. I assume that the SQL for this should appear in the RoleMemberships.sql but it doesn't. AFAIK there are no UI Settings that affect this behaviour (ignore permissions on or off has no affect). 2. The SSMS UI view of the role does not show the securables or the schem ...Show All

• SQL Server sp_xml_preparedocument VS nodes()

  I am considering converting a stored proc which uses sp_xml_preparedocument to a select using the node() syntax. I made two sql scripts, one of each method with identical input xml and ran a query plan on each of them. To my surprise, the Sp_xml_preparedocument seemed to produce the better query plan. The Estimated subtree cost for sp_xml... was 3.36433 for 10000 rows and the estimated subtree cost for nodes() was 421.126 for 60 rows. Am I missing something or is sp_xml_preparedocument still the best method to shred an xml document sp_xml code: DECLARE @idoc INT , @trans_id int , @after_doc xml , @record_type int , @sm_session_id nvarchar ( 50 ), @trigger_start_time datetime , @user_id int , @fo ...Show All

• Smart Device Development How could I lock and unlock the keypad on smartphone

  Hi, I'm writting a program that have to lock the keypad when it is inactive and can unlock the keypad by pressing a single key.But how can I do that,Is there any APIs Thx! BOOL EnableHardwareKeyboard(BOOL bEnable ) will allow you to disable and enable the keyboard. As for getting it to come alive again, you'll only be able to press certain buttons, ones that won't be blocked by disabling the hardware keyboard. Things like the call buttons shouldn't get blocked, so you'll have to catch these button presses to enable the keyboard again. I'm not positive how to do that, I guess you could RegisterHotKey one of those buttons, but I don't the virtual key codes (or if you are allowed to). ...Show All
