• Visual Studio Express Editions DataGridView Before Update Event ?

  In a DataGridView, is there an event before update we can used to perform some tasks, like updating fields of the current DataGridView or updating other tables that are not link to the current view Tanks for your answer the datagridview only shows the data being bound from the datasource, or directly added to it. That's all. In terms of doing operations before the update event, wherever you are placing the code to update the database, only there would be the chance for you to do your editing on wherever it needs to be done as far as I can understand. Sorry if I misunderstood ...Show All

• Visual C# Move objects between System.Collections.List

  Hi! I have two Lists (System.Collections) and I want to move (or copy) objects from the first to the second one. This is my code for(int x = 0;x < list1.Count;x++) { list2.Add(list1[x]) } But every time C# gives this error: Object reference not set to an instance of an object. How can this problem be resolved Thank you! Yes of course, I always make that mistake.

• Windows Forms Readonly databinding with a business object

  I tried to bind a property of a business object to a TextBox control. I used a BindingSource component to accomplish this task. So far so good :-) The property of the business object is a read only property. I thought that data binding recognize this and set the TextBox control to read only. I was wrong. But it's even worse. If I change the text in the TextBox control I can't leave the focus from the TextBox anymore. The focus is trapped in the TextBox control and the user doesn't get any error message. Is it possible that data binding recognize the read only property and set the bound control to read only Can I prevent the TextBox to trap the focus I think the usability for trapping the focus in a control if the validation ...Show All

  Hello, I'm just getting into WCF and would like to host a WFC Service inside a Windows Service but I can't quite figure out how. I can successfully create and use each part independently but merging the two eludes me.

  Hello, I am trying to use a recordable CD as the storage medium for a comma delimited flat file destination in an SSIS package. I am running the developer edition of SQL Server 2005 on Windows XP SP2. I discovered that in the file connection manager for a flat file, the path to the file can point to a directory on the CD-R.
