• .NET Development Dynamically remove textbox

I need code sample. Thanks Arun Hi Arun, When you dynamically add a control to a form, you should always add the control to the Controls collection of the form (this will ensure proper cleanup of all references when the form closes). To remove a control from the form, you can simply remove it from the controls collection. Here's an example (it's in C#, let me know if you need a VB sample): ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Disposing Resources?

  Hi, I've been working on a few game components in my XNA project but I've become curious what is the correct way to dispose of resources that the component loads I load these resources either in LoadGraphicsContent or a load method of my own, but when the component is disposed, UnloadGraphicsContent is not called. I assume UnloadGraphicsContent is only called when the graphics device is reset. Now, the question is, where to I dispose my resources (spritebatch, textures, IO streams) - in the Disposed event If so, how can I detect whether the class is disposed and throw ObjectDisposedExceptions when a public member handling a resource is attempted to be accessed Thanks in advance for any help...

• SQL Server Management Studio: UNWANTED Firing of Triggers

  I have a trigger on a table that updates a 'date_modified' field anytime a row is changed. Like so : CREATE TRIGGER mytrigger ON mytable FOR UPDATE NOT FOR REPLICATION AS UPDATE mytable SET date_modified = GetDate() WHERE keyid = mytable.keyid When the table is opened in Management Studio and only ONE ITEM changed, the trigger fires as expected. BUT once the window is closed, M. Studio is firing the trigger for all rows. Does anyone know a way to prevent this I only want the trigger fired for the one row that was changed AND this includes when the table is viewed in M. Studio. thanks, Running SQL 2005. Don't you need to use the special tables Inserted/Deleted i.e. (note: n ...Show All

• SQL Server Query much slower on 2005 compared to 2000

  We have a database developed using SQL Server 2000. We are in the process of testing it on SQL Server 2005. So far i've not done much testing but it has become apparant quickly that quite a lot of queries are performing much slower in SQL Server 2005. I am currently trying to figure out why a particular query is not performing well. One SQL Server 2000 it runs in around 6 seconds. On SQL Server 2005 it takes around 50 seconds. The query is this... SELECT StartBase, StartPoint, PickupPoint, PickupInstructions, SingleJourney, Destination FROM vwJobs WHERE StartDateTime BETWEEN '2006-09-01' AND '2006-09-23' vwJobs is a view in our database. The view includes many UDF's and also has a UNION which combines two seperate table structures ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA - Microsoft lack of vision

  Its real sad that Microsoft, once again, shows this lack of vision for a games development tool: 1: Get visual: Don't force users to write such a lot of code to do just very little. It reminds the Charles Petzold's "Hello Window" hell of code days. 2: Provide visual tools: Let users choose the components, change their properties and write just the required code for the events. 3: Quick development means quick prototype and minimum learning curve. XNA has a lot of things to learn. Definetively it is NOT for students and hobbists. We will have to wait until someone encapsulates XNA framework into a group of visual components, that can be easily drag & dropped, inspected and tested very easily without having to learn lots of n ...Show All

• Software Development for Windows Vista Custom persistence service and timer activities

  Hello. I have a question regarding how should I recreate the TimerEventSubscription (I use DelayActivities and a custom delay activity) on the Start method of my custom persistence service. I believe that the service is the one that must do that task, am i right If so... how :) Thanks in advance, Matias You don't recreate the subscription - you fire the timer by asking the WorkflowRuntime to load that particular workflow from your store. When you implement a persistence service and persist an instance that has a timer - you must create you own timer mechanism. The SqlWorkflowPersistenceService does this by writing the timeout stamp to the database and has a background thread that polls the databa ...Show All

• Software Development for Windows Vista Get just the current workflow data

  Hello, I have a workflow with several activities. And when I do a SqlTrackingQuery on a current workflow, I get four instances of ActivityTrackingRecord, because there are four activities in my workflow. But I just want to get one instance with the current values of the workflow properties. How can I implement that Thanks for your help. You will need to create a tracking profile and add an WorkflowDataTrackingExtract for all the properties that you would like to access the value for. Like the following: System.Workflow.Runtime.Tracking. WorkflowDataTrackingExtract workflowDataTrackingExtract = new System.Workflow.Runtime.Tracking.

• SQL Server Convert SQLExpress db to Sql Anywhere

  Hi, Is there any way that an existing database in SQL Express can be converted to a SQL Anywhere regards Hi Dharam, SSIS transfers data table by table from a data source to SQL Mobile database.
