• Windows Forms Calculated fields in dataset

  Hi, I need to add custom calculated fields to DataTable of Dataset in following scenario (simplified): There is in-memory cached data as Dictionary<Guid, string>. There is DataTable with columns Id (Guid) and Name (string). Id is being filled by DataAdapter. I need Name field to be calculated (taken from Dictionary object). Is there any way to accomplish that I created DataSet object with DataAdapter. DataTable's OnRowChanging/OnRowChanged are overriden already, so I can't override them in partial DataTable declaration. I can use OnChange event created by DataSet, but doing so I'd have to provide method that creates DataSet, attaches event handler and returns it to the caller. This makes DataSet object inconsistent - ...Show All

• Visual Studio Express Editions Learn about dlls

  I would really love to learn what a dll is, how it is used and in what kind of circumstanses I would need to use one. Here is what I do know about them 1) dll = dynamic link library and that's it (and I am not really sure if that is correct) Does anyone have a test dll that I can look at or at least a reference to where I can learn more aobut them. Thanks in advanced. So, if I understand you correctly, a dll is the same as a module, but it can be used in mulitple different applications. For instance, if I have a function that I have created that I want to use, and I know that it would apply in multiple different then I could create a class library to use that function in the different applications ...Show All

• Software Development for Windows Vista Exception on raising an event

  Hello, I'm developing an example project very similar to expense reporting (lab01), with two event handlers. I can fire the first one (submitted event) without any problems, but when I try to raise the second event (reviewed event) I get an exception that sais: "EventDeliveryFailedException was unhandled" and the message is "Event "RevisatCOF" on interface type "WorkflowValidacio.Interficie" for instance id "ef46e5fa-64c7-4343-9d3c-c62b829f9c37" cannot be delivered." I followed exactly the example in expense reporting, so I have the event declared in my interface and in the implementation class, and I raise the event like this: RevisatCOFEventArgs e = new RevisatCOFEven ...Show All

• Visual Basic Editing Listview subitem contents

  Hi all, Hope someone can help me with this. I have a Listview (details view) with 5 columns. It looks like I can only edit the first column text (with labeledit=true) as the listview control won't let me select the text in the other columns. Is this a limitation in Listview or am I missing something Should I use the DataGridView control instead Thanks in advance. I just did a quick test and changed the column names right in the IDE: (Maybe I missed what you were asking..)

• SQL Server No checkboxes on the Server Roles page for Logins

  Hi, There are no checkboxes when I view the Server Roles page under Security --> Login properties. The page does work. If I highlight a role and click OK, the role is granted.

• Windows Forms lose TreeView events after placing on SplitterContainer Panel

  If I drop a treeview control onto a Windows.Forms.UserControl, when I click on a node, it fires the AfterSelect event. But after cutting it from the primary surface and pasting it into a SplitContainer control (Panel1), the treeview gets populated with nodes but the AfterSelect handler doesn't work. Why is that Is this an object hierachy problem with the controls Or is the panel within a splittercontainer not really a container to host a control. Seems like I have had to actually drop a panel control into the splitcontainer before to host a control, but it doesn't seem like I should have to. Thanks, -Greg When you are cutting and pasting the control from one container to another t ...Show All

• Visual C# How-to: Read Image from database into pictureBox control using a bindingSource.

  Hi all, I am a noobie to C# and have been trying to write an application using sqlce and C# for a Windows Mobile 5.0 device. After much searching, I have not been able to find any examples to assist me. I have a form that is using a BindingSource bound to a table from a SQLCE database. One of the columns in my table is of type Image. I would like to read/write an image to this column and show it in a pictureBox on the form. I understand that the Image is stored as a byte[] in the database and needs to be converted to and from this format, however, I have not been able to find any samples of how to do this with a BindingSource object. For example, I have a table Options that contains the following columns Options { optionId int, companyName ...Show All
