• Windows Forms Override how GridView gets data from DataRow

  I have an app that uses several GridViews, and I was recently asked to encrypt only a few columns in my database. I already have custom classes that extend the DataRow, is there a method or version of the [] accessor I can override that is called by the GridView I need to check if the column being accessed is one of the encrypted ones or not. Thanks. Moving from .NET Framework Data Access and Storage to Windows Forms Data Controls and Databinding . ...Show All

• Smart Device Development Read and write XML files

  Hi, I want to build a software for pc pocket on Windows Mobile 5.0 using VS 2005. I create solutions and add one xml file item into the project, called "data.xml".

• Software Development for Windows Vista Urgent: Scheduling service in Sharepoint workflows

  Hi, Hosting a workflow in sharepoint yields in major scheduling service issue. The manual scheduler service can't be controled and thus the delay activity in turn isn't feasible. A possible walkaround was to create a task with a duedate. A windows service will run on timely basis and checks all the tasks with expiry date and updates them. In theory, updating a task will cause the workflow to trigger the OnTaskChanged method, but in practise, this wasn't the result. When this task is updated, the workflow isn't affected, whereas when manually updating the task an error occurs "event isn't received". The reason is due to the fact that the updated workflow in the windows service doesn't run the scheduler and as aresult, the workf ...Show All

• SQL Server Bulk Insert vs. Data Flow Task (different row results using flat file source)

  I'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination). With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table. I used two different flat file sources and got the following: Flat file 1: Bulk Import Task = 12,649,499 rows; Data Flow Task = 4,215,817 rows Flat file 2: Bulk Import Task = 3,403,254 rows; Data Flow Task = 1,134,359 rows Anyone have any guess as to why this is happening Yeah, thanks for the reply. I've checked the preview and it looks fine. I've also tracked down some of the skipped ...Show All

• SQL Server Key Maintenance and Stored Procedures

  Basically I would like to ask whether parameters can be used to pass the value of the 'symmetric key id', 'certificate' and optionally 'password' to a stored procedure that uses encryption functions. The reason this is appealing is that when encryption keys etc change over time (we have a requirement to decrypt data, destroy and create new keys, then encrypt data every time we lose a staff - don't ask), as we would be passing the value of keys, passwords and certificates as parameters to a standard stored procedure. Hardcoded Example (Working) USE PSS GO CREATE PROC insert_payer_ba -- define parameters @param_rec_id NVARCHAR ( MAX ), @param_bsb NVARCHAR ( MAX ), @param_account NVARCHAR ( MAX ), ...Show All

• Smart Device Development Where is the Active Sync device name located?

  Posted on: 02/22/2007 08:15:24 Not sure if this is the correct place to post but I didn't know where else to ask this question. Unable to program for my device with VS 2005 unless the OS is upgraded. I've had problems with my Viewsonic V37 Pocket PC. I had obtained an OS upgrade CD via ebay. I attempted to upgrade the OS from 2002 to 2003 and it didn't work - for some reason the USB port was unable to detect the device and I had to reset it several times, once for each attempt. I'm still back to the original OS. With each new attempt, I had to rename the device in my computer by a new name as the previous name was still there. How can the old names be removed Where is the device name association located ...Show All

• Software Development for Windows Vista Workflow Persistence, Idle Workflows and External Events

  I've been doing some thinking about how the default workflow persistence services work and how it affects those of us writing complex event-activities (i.e. IEventActivity implementations), and I was curious about something. I was reading Paul Andrew's comment on how the default workflow persistence service will only load persisted workflows that are "ready to run", and how it worked with locking when multiple runtime instances across a farm were using the same persistence database (all very informative stuff). However, what I'm not quite clear on yet is what the "readiness to run" of a persisted workflow is determined. Could someone expand on this a little bit Here's what I'm trying to find out: For example, if an act ...Show All

• Audio and Video Development UserOps again...

  Any help in finding documentation on how to use AVRCP in C# CF 2 appreciated :) Microsoft BT stack APIs are described here  (WM 5.0) and here  (CE 6). I’m not sure if this profile is even supported though and if it is it might be up to OEM to support it or not. If you happen to have 3 rd party BT stack you’d need to contact that 3 rd party to obtain documentation and/or SDK. Link #3 points to one of these manufactures. ...Show All
