• SQL Server Allow Blank in parm not working

  I am using RS2005. I have a data driven parm that I have checked "allow blank" as a value. I cant allow null so that isnt checked. I have even entered a space in the area where you can provide a default value. When I preview the report ... this parameter has <Select a Value> in the combo box. All other parms are filled in with defaults so the report should run. I hit "View Report" and get an error message "Please select a value for the parameter 'ParameterX' " which is the parameter I have said could be blank. Of course if I drop down the list there isnt a blank value to select - and I dont see why I would want to add one and force a selection of spaces ... seems like something is wrong here.

• .NET Development ADO.NET Update Did Not Update DB

  Hi, I am using C# and .NET 2.0 and ADO.NET 2.0 in Visual Studio.NET 2005 running on Windows XP. I am creating an application that reads from a SQL Server 2000 DB using OleDB connections, allow user to do some updates on screen, and then save those updates back to DB. The data I read, most of them I bind to DataGridView on my forms, but there is one form that I bind the data to various text boxes. I load the data into a DataSet, and I go through the DataAdapter and BindingDataSource to bind the data onto the controls. I am also using the OleDBCommandBuilder to build the sql commands. The problem is: when I try to save the changed data back to DB, when I make the Update call on the DataAdapter class, none of the data is updated. ...Show All

• SQL Server Cube usage by users

  Hi, What would be the correct way to generate some kind of log or report that will tell me which user used which cube in which database along with the number of times the user connected to each cube each day The number of queries sent by each user to each cube by day would be ok. I am not interested by the query content for this exercise. I just want Userid, DB name, Cube name and Hits. Then I can take it from there and create a report for our security/sox guy with User name, Cube name, Week of year and number of hits by week, meaning if the users send 36 queries to Cube A on Monday and 2 queries on Friday, it counts for 2 cube accesses for that week. This assume that I use only TCP/IP access but if the same mechanism would work f ...Show All

• .NET Development Database

  It is necessary to use a database on a local computer that will advise, that like Microsoft Access databases can be located any where. having it local has its advantages but more disadvantages. local Advantage: faster access   local disadvantage: you would have to update other databases that other users maybe using, this is a painful job everyone will have their own copy of the database therefore inconsistant records/data   Remote Advantage: everyone uses the same database therefore everything is up to date and everything is stored in one central location backups easily made (to a certain extent) since all data is in one location rather than spread out over se ...Show All
