• Windows Forms Implements IBindingListView Problem

  Does anyone have a VB sample of a collection implementing the  IBindingListView interface. I need to make the filter option availabe from the BindingSource for my objects. Thanks Ken Fair point about declaring unfilteredItems as List<Of T>. I missed that one. Thanks Also, extremely good point about using the proper interface! I guess I've always been a bit rebellious when it comes to following rules. I like to consider myself as "thinking outside the box" ;-) I hope to learn a great deal from you in the future. Cheers. In case anyone is still interested in the dele ...Show All

• .NET Development Data Access Layer; how-to use List<> collection obj. w/o reference to specific type

  Here's my scenario: 1. I have a DAL 2. In my DAL, I want ONE function that will transform an ADOReader resultset into a strong data entity object that I will call an Info entity (e.g. WorkerInfo). My info entity contains only properties, and each field of each row of my Reader will provide the content for the property attributes of my object. 3. I can do this easily for each of my different data entities, but I don't want to have to create a new function for each of them. Instead, I would like to pass to my function what Type of entity is getting filled, as well as my params and proc name needed to fill the ADOReader. 4. Here's a ...Show All

• Visual C# Cannot read from a text file - FileNotFound Exception, although file is there

  Hey guys, For some reason, I keep getting a FileNotFound exception while trying to read from a text file, although the path that the StreamReader is looking in is correct - which I know for a fact. Here is the method that does the reading: public void setDescription(String file) { string currentDir, desc; try { currentDir = Directory.GetCurrentDirectory(); // Read the file as one string. System.IO.StreamReader myFile = new System.IO.StreamReader(currentDir + "\\" + file); desc = myFile.ReadToEnd(); myFile.Close(); label11.Text = desc; } catch(IOExce ...Show All

• Visual Studio How to access reporting dataset after report is run?

  How do you access the dataset that the current instance of the report is run on outside of the report The reason I want to do this is because I have created my own parameter toolbar and want to be able to populate the dropdown menus with data that is returned from the dataset. Specifically, I want to be able to extract things like the UserIDs and/or the Status fields that are returned inside the dataset. I assume you are using server mode, since in local mode you have to supply the data to the report object. In server mode, the viewer never gets the underlying dataset from the server, so it can't return ...Show All
