• Visual Studio DomainClass XXX is not abstract, and is neither a root of the model nor embedded within it.

  How I can solution this warning : DomainClass FormElement is not abstract, and is neither a root of the model nor embedded within it. The DomainClass FormElement inherits from abstract class. Thank you so much. In your domain model, every concrete DomainClass except one must be (either directly or indirectly via inheritance) the target of an embedding relationship. The one that is not - the Root - must be mapped to the diagram and marked as the root class of the editor. Unless these constraints are satisfied, the tool that you are building cannot create connected models that can be serialized. ...Show All

• Windows Forms How do I install to a custom location on client PC with VS 2005 ClickOnce?

  I can't seem to figure out how to set things up so that after I have published the app and the user actually installs the windows app on their machine it installs to a location I desire.

• .NET Development BaseNumberConverter throws Exception of type System.Exception (BUG in framework?)

  Last months I try to improve my programming style so that I only catch Exceptions related to the method I execute. I had a small discussion about that in following forum http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=806282&SiteID=1 and you find a lot of other resources why you should do that. Today I was converting Padding to string and back to Padding. And when I tried to convert an invalid string, I received an exception of the type System.Exception . I looked a bit deeper in the Framework and the exception is thrown in the method FromStringError of BaseNumberConvertor . internal virtual Exception FromStringError ( string failedText, Exception innerException) { return new Exception ( SR .

• .NET Development Is there an object for this?

  Hi, I'm trying to find an object to use, not sure if it exists. I need to have a collection where I can add objects (Windows Forms), and navigate through the collection.

• .NET Development Handling UniqueConstriant Exceptions at DataTable level?

  The example below will cause a ConstarintException to occur. I would like to handle these exceptions at the Table level so that I can determine what constraint was violated on what column and provide a more helpful user friendly message to the end user by putting some text in the RowError and ColumnError fields... The problem is, I cannot use a try catch block because I will not be adding the new row programmatically. I will be using a DataGridView which handles the NewRow() and Rows.Add() process. When the error bubbles up to the DataGridView I can catch it in the DataGridView.DataError event. However this only works if an existing row is changed to hold values that violate the constraint. If a new row causes the violation, the ...Show All
