• Windows Forms DataGridView CustomComboColumn BackColor turning black when DataBound

  My issue is that i am creating a Custom Combo Cell that inherits DataGridViewComboBoxCell, that will set its datasouce from the business object that the DataGridView is bound to. I am using the OwningRow property to get to the business object and the OwningColumn to get the DataPropertyName. The properties of the the BO are actually what we call "SmartObjects", They provide the meta data from the database and so on. These objects also have methods to get lists of valid values for each field. These methods are returning a DataTable and that is what is eventually becoming the DataSource of the Combo Box Editing Control. The list is bing populated with the correct value but for some reason the backcolor of the editing control is black. ...Show All

• SQL Server Backup database with encrypted column data

  Hi, I have database with encrypted column data in my customer server. Sometime, I might need to backup their database back to office for troubleshooting. How could I backup/restore master key, symmetric and asymmetric key created for my database Thank you You don't need to backup or restor any key, to be able to use your database backup on another machine. You just need to know the password protecting the database master key. On the machine on which you restore the database, you will have to reencrypt this master key with the service master key of the database server. You can do this with the following statements: OPEN MASTER KEY DECRYPTION BY PASSWORD = 'password' ALTER MASTER KEY ADD ENCRYPTION B ...Show All

• Software Development for Windows Vista Security Shield "Unidentified Publisher"

  After searching everyplace I could think of, this is the last hope. When installing my application on Vista (every version so far) I get a dialog box that pops up stating "An unidentified program wants access to your computer". On this dialog box, it states "Unidentified Publisher". I don't mind the "...program wants access to your computer" part. I just want to try and switch the "Unidentified Publisher" to state my companies name. Does anyone know how this is done Is it done by the installer software, or is this what "digital signing" is supposed to handle If it is done by the installer software, does anyone know which installers currently support this I currently have acces ...Show All

• Windows Forms Change column type DataGrid

  Hello, I'm a Costa Rican student of systems eng. C# I have a DataGrid bounded to a DataTable, and I want to change the DataGrid column type from int to String but I can't do it like this: dt.Columns[7].DataType = typeof(System.String); because the DataTable is filled already. Is there anyway that I can do that The thing is that I want to change the int value "0" (or "1" or "2") fom the database's table to a String in the DataGrid. Because those numbers have a meaning, and I need to translate those numbers into text. 0 means "frecuent" cust 1 means "credit" cust 2 means "black list" cust I need to put those strings into the DataGrid.

• SQL Server Question on Internal Activiation

  Hi Could it be assumed that a stored procedure, activated internally by Service Broker, is executed under the same environmental variables (resource allocation specifically) than when that same stored procedure is executed via an EXEC statement from a non-Service Broker procedure When I have 10 of these procedures running (somewhat concurrently) overall performance is not even close as to when I let Service Broker activate the procedure via 10 messages on the queue. If all variables are equal than I am not sure why this is. Or is it possible that everything is not equal Thanks Paul Are you certain that all 10 are actually firing up at the same time via SSB   It's possible tha ...Show All
