datasource

问题 In Dashcode, if I have a dataSource that has, for example, 2 fields called 'FirstName' and 'Last Name', how do I concatenate the 2 fields into one text field in a list view? I'm fairly sure it must be to use a value transformer, so say that I assign the 'FirstName' field to the textfield, and add a value transformer... how do I then add the 'LastName' value to the 'value' variable in the transformer. I'm sure it's to do with dashcode.getDataSource and valueForKeyPath and I think I'm close to

问题 The db password expired and it needs to be updated, how do I update the password for a Cognos Data Source? 回答1: In Cognos Administration, under Configuration tab, the Data Source Connections section (on the left): Clicking on the Data Source name will bring give you the Connection for that Data Source (the Connection might have the same name as the Data Source).

问题 I have created an application in Visual Studio (C#) that makes use of a datagridview. Now, when I assign the DataSource of that datagridview, it automatically selects the first row, and executes my code for selection. Since I frequently reassign that datasource, this is not desireable. Is there any way to change it so it doesn't automatically make that first select, and only relies on the user's selections? Thanks! In response to the comment of Darshan Joshi: Apart from the auto-generated

问题 I have an ASP.Net Web site that displays various SSRS reports using the Microsoft Report Viewer Control. I need to be able to specify a data source at runtime. It seems like I should be able to just specify the name of a "shared" data source when I render the report, but I sure can't find a way to do that. The only thing I've found so far that works is to use an "embedded" data source. I'm not real crazy about that, but if that's my only option it will have to do. Anybody know how to specify
